Description
본 발명은 수처리용 고체약품 투입기에 관한 것으로, 특히 정수장의 정수처리를 위하여 이취미(異臭味)제거용 활성탄 및 응집보조제용 소석회를 일정 농도로 용해하여 용해수를 수처리장의 원수에 연속적으로 공급하기 위하여 설치되는 수처리용 고체약품 투입기에 관한 것이다.The present invention relates to a solid chemical injector for water treatment, and in particular, dissolves deodorizing activated carbon and coagulant aid lime at a constant concentration to purify the purified water plant, and continuously supplies dissolved water to the raw water of the water treatment plant. It relates to a solid chemical input device for water treatment is installed to.
여러가지 요인으로 점차 수질이 악화되어 일반적인 약품과 정수처리과정으로는 한계가 있어 활성탄, 소석회 투입 및 고도 정수처리방법이 요구되는 실정에 있다.Due to various factors, the water quality deteriorates gradually, and thus there is a limit to general chemicals and water treatment processes, and activated carbon, slaked lime input, and advanced water treatment methods are required.
일반적인 정수처리 약품인 염소로는 일반조류를 제거할 수 있으나, 갈수기에 발생하는 남조류에 염소를 투입하게 되면 오히려 이취미가 발생하여 일반가정에서 음용하기가 어려움으로 이러한 이취미를 제거하기 위하여 활성탄을 투입하게 되는 것이다.Chlorine, which is a general water treatment chemical, can remove general algae, but when chlorine is introduced into the algae generated during the dry season, odors are generated, which makes it difficult to drink them at home. It will be committed.
또한, 소석회는 정수처리과정중 응집보조제로 사용하여 정수생산의 효율성을 확보하기 위한 것으로, 침전과정중 중금속이나 비중이 큰 조류제거에 사용되고 있다.In addition, slaked lime is used as a coagulant aid during the water treatment process to secure the efficiency of water purification, and is used to remove heavy metals or algae having a high specific gravity during the precipitation process.
이들 활성탄과 소석회는 고체약품으로 분류되고 있으며, 함수율이 60%정도 포함되어 있는 고체입자 또는 분말상태로 수처리용 고체약품 투입기의 용해조에 투입하여 용해한 후 혼화지 또는 착수정 등에 공급하여 원수를 정화하게 된다.These activated carbons and slaked lime are classified as solid chemicals.They are put into the dissolution tank of solid chemical feeder for water treatment in the form of solid particles or powder containing about 60% water content, dissolved, and then supplied to mixed papers or watering wells to purify raw water. .
활성탄과 소석회는 동시에 투입하는 경우보다 각각 별도로 대부분 동시에 투입하는 경우보다 각각 별도로 투입하는 경우가 많다. 그러나 원수 수질이 악화되면 활성탄과 소석회를 동시에 투입하여야 하는 경우도 있다.Activated carbon and slaked lime are often added separately from each other than simultaneously. However, when raw water quality deteriorates, activated carbon and slaked lime may need to be added at the same time.
그리고 이들 약품들은 원수유량에 비례하여 연속적으로 투입하여야 하며, 필요에 따라 투입량의 변화가 가능하여야 한다.These drugs should be injected continuously in proportion to the amount of raw water flow, and the amount of input should be changeable as needed.
도 1은 종래의 수처리용 고체약품 투입기를 나타낸 것으로, 그 구성과 작동은 다음과 같다.1 shows a conventional solid chemical injector for water treatment, the configuration and operation of which are as follows.
도 1에 도시한 바와같이, 최상측으로부터 하측에 이르기까지 호퍼(10)와 정량공급부(20)와 용해조(30)로 대별된다.As shown in FIG. 1, it is divided roughly into the hopper 10, the fixed-quantity supply part 20, and the dissolution tank 30 from the uppermost side to the lower side.
상기한 호퍼(10)는 활성탄이나 소석회가 최초 투입되어 일시저장되는 곳으로 상부에는 약품투입구(11)가 형성되어 있으며 내부의 상측에는 스크린(12)이 설치되고 내부 중앙에는 배출기(13)가 설치되어 있고 외측에는 바이브레이터(14)가 설치되어 있다. 그리고 호퍼(10)의 상단부에는 집진기(15)를 연결하여 분진을 제거할 수 있도록 하고 있다.The hopper 10 is a place where activated carbon or slaked lime is first stored and temporarily stored, and a chemical inlet 11 is formed at an upper portion thereof, and a screen 12 is installed at an upper side thereof, and an ejector 13 is installed at an inner center thereof. The vibrator 14 is provided outside. And the upper end of the hopper 10 is connected to the dust collector 15 to remove the dust.
상기한 정량공급부(20)에는 스크류컨베어(21)가 설치되어 호퍼(10)로부터 낙하되는 약품을 용해조(30)에 정량적으로 공급할 수 있도록 하고 있다.The above-mentioned fixed quantity supply part 20 is provided with a screw conveyor 21 to supply the chemicals falling from the hopper 10 to the dissolution tank 30 quantitatively.
상기한 용해조(30)에는 교반기(31)가 설치되어 용해조(30)에 공급되는 약품을 정수와 혼합하여 원활하게 용해할 수 있도록 하고 있다.The agitator 31 is provided in the dissolution tank 30 to mix the chemicals supplied to the dissolution tank 30 with purified water so that the dissolution can be smoothly dissolved.
미설명 부호 32는 "정수공급관"이며, 33은 "펌프", 34는 "배출관", 35는 "분배조"이다.Reference numeral 32 is a "water supply pipe", 33 is a "pump", 34 is a "discharge pipe", 35 is a "distribution tank".
이와같은 구성으로 된 종래의 수처리용 고체약품 투입기의 작동은 다음과 같다.The operation of the conventional water treatment solid chemical injector having such a configuration is as follows.
정수공급관(32)을 통하여 용해조(30)에 정수를 충만시키고 집진기(15)를 가동한 후에 호퍼(10)의 상부에 있는 약품투입구(11)를 통하여 호퍼(10) 내에 약품을 투입하고, 배출기(13), 바이브레이터(14), 스크류컨베어(21), 교반기(31)를 작동시킨다.After filling the dissolution tank 30 with purified water through the purified water supply pipe 32 and operating the dust collector 15, the chemicals are introduced into the hopper 10 through the chemical inlet 11 at the upper portion of the hopper 10, and the ejector is discharged. (13), the vibrator 14, the screw conveyor 21, and the stirrer 31 are operated.
호퍼(10)에 투입되어 스크린(12)을 통과한 약품은 모터의 구동에 의하여 회전되는 배출기(13)의 배출익(13a)에 의하여 호퍼(100)의 하측으로 배출되면서 정량공급부(20)로 투입된다. 정량공급부(20)로 투입된 약품은 스크류컨베어(21)에 의하여 정량적으로 용해조(30)에 투입되어 모터에 의하여 구동되는 교반기(31)의 임펠러(31a)에 의하여 정수에 용해된 후 일정 농도의 용해수는 배출관(34)을 통하여 분배조(35)로 공급되고, 이 분배조(35)에 의하여 도시하지 않은 정수장의 착수정, 혼화지, 침전지 등의 원수(오염수)에 투입된다.The chemicals introduced into the hopper 10 and passed through the screen 12 are discharged to the lower side of the hopper 100 by the discharge blades 13a of the ejector 13 rotated by the driving of the motor to the fixed-quantity supply unit 20. Is committed. The chemicals injected into the fixed-quantity supply unit 20 are quantitatively introduced into the dissolution tank 30 by the screw conveyor 21 and dissolved in the purified water by the impeller 31a of the stirrer 31 driven by the motor. Water is supplied to the distribution tank 35 through the discharge pipe 34, and the distribution tank 35 is supplied to raw water (polluted water) such as a water well, a mixed paper, and a sedimentation basin of a water purification plant not shown.
그러나, 종래의 고체약품 투입기는 다음과 같은 단점이 있는 것이다.However, the conventional solid drug injector has the following disadvantages.
첫째, 종래에는 호퍼(10)에 약품이 과대투입됨에 따라 호퍼(10)에 충만된 양에 비례하여 정량공급부(20)에 이르기 까지 큰 하중이 작용함에 따라 스크루컨베어(21)의 상부에 있는 약품의 응집력과 밀도가 커지게 된다. 따라서 도2에 도시한 바와같이 스크류컨베어(21)의 상부에 적층된 약품층에 동공(hole)현상이 발생하게 되고 약품이 불규칙적으로 스크류컨베어(21)에 공급된다. 결국, 약품이 스크류컨베어(21)의 회전수비에 따른 정량적 투입이 않되어 용해수의 농도를 일정하게 유지시킬 수 없으며, 응집된 약품이 스크류컨베어(210)에 일시에 하중을 가하여 불규칙적으로 과부하가 걸려 스크류컨베어(20)의 구동계통에 손상을 초래하게 된다.First, in the prior art, the drug in the upper portion of the screw conveyor 21 as a large load to the quantitative supply portion 20 in proportion to the amount filled in the hopper 10 as the drug is excessively injected into the hopper 10. The cohesion and density of becomes large. Therefore, as shown in FIG. 2, a hole phenomenon occurs in the chemical layer stacked on the upper portion of the screw conveyor 21, and the chemical is irregularly supplied to the screw conveyor 21. As a result, the chemicals cannot be quantitatively injected according to the rotational ratio of the screw conveyor 21, so that the concentration of the dissolved water cannot be kept constant. This will cause damage to the drive system of the screw conveyor 20.
둘째, 종래에는 용해조(30)에 설치된 교반기(31)는 모터에 의해 회전되는 임펠러(31a)에 의하여 약품을 용해하는 방식이므로 모터를 구동시키기 위한 별도의 동력원(전력)이 소요되었다.Second, the conventional stirrer 31 installed in the dissolution tank 30 is a method of dissolving the drug by the impeller 31a rotated by the motor, so a separate power source (power) was required to drive the motor.
셋째, 종래에는 정수의 공급을 단순히 수동으로 조작하여 정량적으로 용해조(30)에 공급하게 됨으로 약품의 양과 조건의 변화에 따라 정수의 공급량을 적당히 조절하여 용해수의 농도를 일정하게 유지시키기 어려운 단점이 있었다.Third, in the related art, the supply of purified water is quantitatively supplied to the dissolution tank 30 simply by manually manipulating the purified water, so that it is difficult to maintain the concentration of the dissolved water by adjusting the amount of purified water appropriately according to the amount of chemicals and the conditions. there was.
본 발명의 목적은 호퍼에 있는 약품의 하중이 정량공급부로 전달되지 않도록 함으로써 동공현상에 따른 용해조에 투입되는 약품의 양을 일정하게 유지함과 동시에 스크류컨베어에 불규칙한 과부하가 걸리지 않도록 하는데 있다.An object of the present invention is to prevent the load of the drug in the hopper to be delivered to the metered supply portion to maintain a constant amount of chemicals injected into the dissolution tank according to the pupil phenomenon and to prevent the overload of the screw conveyor.
본 발명의 또다른 목적은 용해조에 공급되는 정수가 용해조에서 분무되도록 함으로써 별도의 동력이 소요되는 교반기를 배제하는데 있다.Another object of the present invention is to exclude the stirrer that requires a separate power by allowing the purified water supplied to the dissolution tank is sprayed in the dissolution tank.
또한, 본 발명의 목적은 정수의 공급량을 자동적으로 조정할 수 있도록 하는데 있다.It is also an object of the present invention to automatically adjust the supply amount of purified water.

호퍼(100)에 투입된 약품은 스크린(120)을 통과한 약품은 모터의 구동에 의하여 회전되는 배출기(130)의 배출익(130a)에 의하여 호퍼(100)의 하측으로 가압되고 로터리 밸브의 회전에 의하여 일정량씩 정량공급부(200)의 스크류컨베어(210)에 투하된다.The chemical injected into the hopper 100 is passed through the screen 120 is pressed by the discharge blade 130a of the ejector 130 is rotated by the drive of the motor to the lower side of the hopper 100 and to the rotation of the rotary valve By a predetermined amount is dropped into the screw conveyor 210 of the metering unit 200.
정량공급부(200)로 투입된 약품은 스크류컨베어(210)에 의하여 정량적으로 용해조(300)에 투입되면서 노즐(510)에 의하여 분사되는 정수와 접촉하면서 용해되고, 용해조(300)에 정수가 충만된 경우에는 회오리 물살에 의하여 약품이 고르게 교반되어 원활이 용해된다.The chemicals injected into the fixed-quantity supply unit 200 are dissolved in contact with the purified water injected by the nozzle 510 while being quantitatively introduced into the dissolution tank 300 by the screw conveyor 210, and the purified water is filled in the dissolution tank 300. The chemicals are evenly stirred and smoothly dissolved by the whirlwind.
약품이 용해된 용해수는 용해조(300)의 한단부에 있는 배출관(340)을 통하여 분배조(350)로 공급되고, 이 분배조(350)에 의하여 도시하지 않은 정수장의 착수정, 혼화지, 침전지 등의 원수(오염수)에 투입된다.Dissolved water in which the chemical is dissolved is supplied to the dispensing tank 350 through the discharge pipe 340 at one end of the dissolution tank 300, and the dispensing tank, the mixed paper and the sedimentation basin of the water purification plant not shown by the dispensing tank 350. It is injected into raw water (contaminated water).
상술한 바와같이 본 발명은 호퍼(100)의 하단부에 로터리 밸브에 의하여 약품의 하중이 정량공급부(200)로 전달되지 않도록 함으로써 정량공급부(200)에서 약품층에 동공현상이 발생되는 것을 방지하고 스크류컨베어(210)에 의하여 용해조(300)에 투입되는 약품의 양을 일정하게 유지되도록 함과 동시에 스크류컨베어(210)가 불규칙한 과부하 없이 원활이 작동되는 장점이 있다.As described above, the present invention prevents pupils from occurring in the chemical layer in the fixed-quantity supply unit 200 by preventing the load of the chemicals from being transferred to the fixed-quantity supply unit 200 by the rotary valve at the lower end of the hopper 100 and the screw. Conveyor 210 to maintain the amount of the chemicals injected into the dissolution tank 300 and at the same time has the advantage that the screw conveyor 210 is smoothly operated without irregular overload.
그리고, 본 발명은 분사관(500)에 의하여 정수를 용해조(300)에서 분사되도록 함으로써 별도의 동력이 없이 기존의 펌프구동에 의하여 자연적으로 약품을 용해 및 교반할 수 있는 장점이 있다.In addition, the present invention has the advantage that by dispensing the purified water from the dissolution tank 300 by the injection tube 500 can naturally dissolve and stir the chemicals by the conventional pump drive without a separate power.
또한, 본 발명은 정수공급관(320)에 자동 유량조절밸브(600)를 설치하여 정수의 공급량을 자동적으로 조정할 수 있도록 함으로서 용해수의 농도를 일정하게 조정할 수 있는 장점이 있다.In addition, the present invention has the advantage that it is possible to constantly adjust the concentration of the dissolved water by installing the automatic flow rate control valve 600 in the purified water supply pipe 320 to automatically adjust the supply amount of purified water.
