Description
技术领域technical field
本发明涉及污水污泥处理领域,具体地说是一种污水污泥高效深度减量化处理装置。The invention relates to the field of sewage sludge treatment, in particular to a high-efficiency deep reduction treatment device for sewage sludge.
背景技术Background technique
污泥是污水处理后的产物,当前污水处理后产生的大量污泥需要进一步处理,而脱水是污泥处理的重要环节,其目的是将污泥内大部分水分脱除,使固体高度富集,大幅减少污泥体积以节省污泥处理的成本,提高污泥热值和节约能源,对于污泥的减量化及后续处置具有重要意义。机械脱水是最有效、能耗最少的脱水方式,当前采用调理及机械方法对污泥进行深度脱水一般情况下可使含水率达到80%-60%。Sludge is the product of sewage treatment. At present, a large amount of sludge produced after sewage treatment needs further treatment, and dehydration is an important part of sludge treatment. Its purpose is to remove most of the water in the sludge and make the solids highly enriched. , significantly reduce the volume of sludge to save the cost of sludge treatment, increase the calorific value of sludge and save energy, which is of great significance for the reduction and subsequent disposal of sludge. Mechanical dehydration is the most effective dehydration method with the least energy consumption. Currently, deep dehydration of sludge by conditioning and mechanical methods can generally make the moisture content reach 80%-60%.
机械脱水方式及设备主要有带式过滤脱水、离心脱水、板框压滤脱水三大类。对于市政污泥而言,带式过滤机、叠螺脱水机、离心机脱水后的滤饼含水率约在75%-80%,隔膜板框压滤机脱水的污泥含水率一般在60%左右。Mechanical dehydration methods and equipment mainly include three categories: belt filter dehydration, centrifugal dehydration, and plate and frame filter dehydration. For municipal sludge, the moisture content of the filter cake dewatered by belt filter, stacked screw dehydrator, and centrifuge is about 75%-80%, and the moisture content of sludge dewatered by diaphragm plate and frame filter press is generally 60%. about.
超高压弹性压榨机是一种压力更大,效率更高的压滤设备和固液分离设备,整个过程主要分为进料--弹性压榨--接液--卸料等四个过程。该设备压力直接来自液压油缸的压力,为直接压榨,压榨压力可达到5-7 MPa单批次工作周期为1.0~1.5h,工作效率为隔膜压滤机的3-4倍,脱水后污泥含水率可以达到50%左右。但存在能耗大、设备成本高、压榨弹簧需要经常更换等问题。The ultra-high pressure elastic press is a filter press and solid-liquid separation equipment with higher pressure and higher efficiency. The whole process is mainly divided into four processes: feeding - elastic pressing - receiving liquid - unloading. The pressure of the equipment comes directly from the pressure of the hydraulic cylinder. It is direct pressing. The pressing pressure can reach 5-7 MPa. The moisture content can reach about 50%. However, there are problems such as large energy consumption, high equipment cost, and frequent replacement of pressing springs.
由上述可知,可将污泥含水率将至60%以下的隔膜板框压滤机及超高压弹性压榨机,其工作流程都是先腔体内进料,然后再压榨,进料和压榨是分先后进行的,而且拉板的时候需要单块或者分批拉板,导致工作周期过长,工作效率不高,以至隔膜板框压榨机一个工作周期需要2-3小时。另外,污泥脱水后的含水率一般是根据经验来确定,很难达到一个较为准确的含水率及目标的含水率,可预测性较差,给污泥的后续使用带来一定的影响,难以实现低成本、高效率的污泥减量化处理。It can be seen from the above that the working process of the diaphragm plate frame filter press and the ultra-high pressure elastic press that can reduce the moisture content of the sludge to less than 60% is to feed the material in the cavity first, and then press it. The feeding and pressing are divided into two steps: It is carried out one after another, and when pulling the plate, it needs to be pulled individually or in batches, resulting in a long working cycle and low work efficiency, so that a working cycle of the diaphragm plate frame press takes 2-3 hours. In addition, the moisture content of sludge after dehydration is generally determined based on experience, and it is difficult to achieve a more accurate moisture content and target moisture content, and the predictability is poor, which will have a certain impact on the subsequent use of sludge. Realize low-cost and high-efficiency sludge reduction treatment.

本实施例所涉及的电气结构部分可以通过统一的控制器10予以控制,即所述的控制器10与水分在线检测仪2.5、电磁换向阀1.3、推拉油缸5、快开驱动油缸9电气连接;同时在每个脱水单元的进料口设置进料管阀门连接,也与控制器10电气连接,所述的每个脱水单元上的进料口设有进料管,并与一根总的进料管相连。The electrical structure part involved in this embodiment can be controlled by a unified controller 10, that is, the controller 10 is electrically connected with the moisture online detector 2.5, the electromagnetic reversing valve 1.3, the push-pull cylinder 5, and the quick-opening drive cylinder 9 ; At the same time, the feeding port of each dehydration unit is provided with a feed pipe valve to connect with the controller 10. The feeding tube is connected.
本装置的工作原理如下:The working principle of this device is as follows:
工作开始时,推拉油缸驱动支撑板运动到一定位置,快开机构关闭限位顶块,支撑板被固定在一个位置脱水筒体的外侧一端,支撑板和挤压板形成一个压滤腔,含水率90%-99%的污水污泥通过螺杆泵或者隔膜泵输送同时进入双向油缸其中一侧(如左侧)所有的脱水单元,此时左侧进料口的阀门打开,右侧进料口关闭,污泥进入,经过滤布水分通过挤压板和支撑板的流体通道进入到封板的排水管中排出,而污泥停留在压滤腔内,随着进入的污水污泥越来越多,压滤腔内的污泥也越来越多,这一阶段为进料脱水,脱水压力为螺杆泵或者隔膜泵的工作压力,约0.6-0.8MPa。When the work starts, the push-pull cylinder drives the support plate to move to a certain position, the quick-opening mechanism closes the limit top block, the support plate is fixed at the outer end of the dehydration cylinder at a certain position, the support plate and the extrusion plate form a press filter chamber, and the water The sewage sludge with a rate of 90%-99% is transported by a screw pump or a diaphragm pump and simultaneously enters all the dehydration units on one side (such as the left side) of the two-way cylinder. At this time, the valve of the left feed port is opened, and the right feed port Closed, the sludge enters, and the filtered water enters the drain pipe of the sealing plate through the fluid channel of the squeeze plate and the support plate to be discharged, while the sludge stays in the filter press chamber, as the incoming sewage sludge becomes more and more There are more and more sludge in the press filter cavity. This stage is feed dehydration, and the dehydration pressure is the working pressure of the screw pump or diaphragm pump, about 0.6-0.8MPa.
另一方面,进料压力对双向油缸的左侧活塞杆也施加0.6-0.8MPa的压力,此时双向油缸不主动加压,为自然状态,该压力通过高压油缸的活塞及右侧活塞杆施加到右侧的挤压板上,从而实现对污泥的低压压榨脱水,右侧污泥被压缩,左右活塞杆、左右脱水单元的挤压板同时向右端运动,左侧的压滤腔空间逐渐加大,进泥量也进一步增大,为一种可变腔体的脱水过程,随着左侧进泥量逐渐增大,脱水后的污泥已经充满左端的压滤腔,右侧的污泥经过长时间的0.6-0.8MPa的压力压榨,水分很难再被挤出,此时,双向油缸左腔通入高压油压,使得右脱水单元的压榨压力达到5-7MPa,右脱水单元在高压压榨下进一步脱水被被进一步压缩,此阶段为高压压榨脱水阶段,左右活塞杆、左右脱水单元的挤压板继续向右侧运动,左侧的压滤腔进一步变大,污水污泥可通过左侧进泥管继续进入到左侧脱水单元进一步脱水,水分通过左右两侧的排水管排出。此时,污泥水分在线检测仪实时检测右侧污泥的含水率,当污泥达到所要求的含水率时,控制器发出信号给快开装置,快开装置打开,控制器同时发出信号给推拉油缸,推拉油缸将支撑板拉开,同时双向油缸推动右侧活塞杆,将污泥推送出去,污泥掉落到物料输送装置上输送出去。污泥输送完成后,右侧推拉油缸将支撑板推回到脱水筒体上,同时快开装置关闭。On the other hand, the feed pressure also exerts a pressure of 0.6-0.8 MPa on the left piston rod of the two-way oil cylinder. At this time, the two-way oil cylinder does not actively pressurize and is in a natural state. The pressure is applied through the piston of the high-pressure oil cylinder and the right piston rod. to the extrusion plate on the right, so as to realize the low-pressure press dehydration of the sludge, the sludge on the right is compressed, the left and right piston rods, and the extrusion plates of the left and right dehydration units move to the right end at the same time, and the space of the pressure filter chamber on the left gradually It is a variable cavity dehydration process. As the amount of sludge on the left side gradually increases, the dehydrated sludge has filled the pressure filter chamber at the left end, and the sludge on the right side After the mud has been squeezed under the pressure of 0.6-0.8MPa for a long time, the water is difficult to be squeezed out. At this time, the left chamber of the two-way oil cylinder is connected with high-pressure oil pressure, so that the pressing pressure of the right dehydration unit reaches 5-7MPa. Further dehydration under high-pressure pressing is further compressed. This stage is the high-pressure pressing dehydration stage. The left and right piston rods and the extrusion plates of the left and right dehydration units continue to move to the right, and the pressure filter chamber on the left becomes larger, and the sewage sludge can pass through. The left mud inlet pipe continues to enter the left dehydration unit for further dehydration, and the water is discharged through the drain pipes on the left and right sides. At this time, the online sludge moisture detector detects the moisture content of the sludge on the right side in real time. When the sludge reaches the required moisture content, the controller sends a signal to the quick-opening device. When the quick-opening device is opened, the controller sends a signal to the Push-pull oil cylinder, the push-pull oil cylinder pulls the support plate apart, and at the same time, the two-way oil cylinder pushes the right piston rod to push the sludge out, and the sludge falls to the material conveying device to be transported out. After the sludge conveying is completed, the push-pull oil cylinder on the right pushes the support plate back to the dewatering cylinder, and at the same time, the quick-opening device is closed.
右侧脱水单元完成了进料脱水、初步压榨脱水、以及高压压榨脱水过程,而左侧有脱水单元只完成了进料脱水。此时,右侧进泥管阀门打开,左侧的进泥管阀门关闭,污水污泥进入到右侧脱水单元,水分通过滤布及挤压板、支撑板上的流体通道进入到封板及排水管排出,污泥则被截留在压滤腔内,右侧的进料压力通过高压油缸的活塞杆对左侧已经过前期进料脱水的污泥进行低压压榨脱水,左侧污泥被压缩,高压油缸的左右活塞杆、左右脱水单元的挤压板向左侧运动,随着脱水的进行,右侧腔体充满脱水污泥,此时,控制器发出信号给电磁换向阀,高压油进入到高压油缸的左侧腔体,对左侧污泥进行高压压榨脱水,污泥被进一步脱水及压缩,双向油缸的左右活塞杆、左右脱水单元的挤压板继续向左侧运动,此时右侧的压滤腔体进一步增大,污水污泥可继续进入。当污泥水分在线检测仪实时检测到左侧污泥的含水率达到要求时,控制器发出信号给左侧的快发装置及推拉油缸,快开装置打开,推拉油缸将支撑板拉开,挤压板推动污泥向做运动将污泥推出脱水筒体,污泥掉落到污泥输送器输出。一个周期完成,如此往复循环。The dehydration unit on the right completes the feed dehydration, preliminary press dehydration, and high-pressure press dehydration, while the dehydration unit on the left only completes the feed dehydration. At this time, the valve of the mud inlet pipe on the right is opened, the valve of the mud inlet pipe on the left is closed, the sewage sludge enters the dehydration unit on the right, and the water enters the sealing plate and the The sludge is discharged from the drain pipe, and the sludge is trapped in the filter chamber. The feed pressure on the right passes through the piston rod of the high-pressure cylinder to perform low-pressure dehydration on the sludge that has been dehydrated by the previous feed, and the sludge on the left is compressed. , the left and right piston rods of the high-pressure oil cylinder and the extrusion plates of the left and right dehydration units move to the left. As the dehydration progresses, the cavity on the right side is filled with dewatered sludge. At this time, the controller sends a signal to the electromagnetic reversing valve, and the high-pressure oil Enter the left cavity of the high-pressure oil cylinder, press and dehydrate the sludge on the left under high pressure, and the sludge is further dehydrated and compressed. The left and right piston rods of the two-way oil cylinder and the extrusion plates of the left and right dehydration units continue to move to the left. The pressure filter cavity on the right is further enlarged, and the sewage sludge can continue to enter. When the sludge moisture online detector detects in real time that the moisture content of the sludge on the left reaches the requirement, the controller sends a signal to the quick-release device and the push-pull cylinder on the left, the quick-release device opens, and the push-pull cylinder pulls the support plate apart to squeeze The pressure plate pushes the sludge to move to push the sludge out of the dewatering cylinder, and the sludge falls to the sludge conveyor for output. One cycle is completed, and so on.
快开装置工作原理为,快开油缸推动快开主杆、快开连杆带动换向圈转动,换向圈转动同时内部的凸轮线型推动限位顶块向下运动,实现限位,当快开油缸反向运动时,带动换向圈反向转动,此时,限位顶块在弹簧作用下打开。The working principle of the quick-opening device is that the quick-opening oil cylinder pushes the quick-opening main rod and the quick-opening connecting rod to drive the reversing ring to rotate, while the reversing ring rotates and the internal cam line pushes the limit top block to move downward to realize the limit. When the quick opening oil cylinder moves in reverse, it drives the reversing circle to rotate in reverse, and at this time, the limit jack is opened under the action of the spring.
