Description

Liquid Dispenser {LIQUID SPLITTER}

The present invention relates to a liquid dispensing apparatus, and more particularly, to a liquid dispensing apparatus capable of precisely adjusting the supply ratio of liquid and continuously supplying a constant ratio of liquid.

In general, a liquid distributor is a liquid distributor used in petroleum refining, petrochemical and fine chemicals, washing towers and absorption towers based on distillation, absorption, and cooling for the removal of harmful gases or organics.

A device for distillation, absorption and cooling, which is currently used industrially, is a column, which separates a desired substance through gas-liquid contact. Recently, a distillation wall type distillation column is used to save energy and reduce investment costs. It is a structure that combines the functions of two or more columns into one column, and the liquid at the upper side must be distributed at a desired ratio to the lower two separation sections. In this case, the liquid distribution device adjusts the supply ratio of the liquid.

However, the above conventional liquid dispensing device rotates the feeder to both sides by a set angle through the rotational movement of the shaft, and supplies liquid according to the ratio of the time stopped on one side and the time stopped on the other side for a certain time. It has a structure in which the ratio is determined. Therefore, there is a problem in that the continuous supply of the liquid is not made while the feeder is rotated from one side to the other side, causing pulsation and degrading the performance of the packing.

In addition, the continuous rotational movement of the shaft increases the consumption of compressed air and the durability is low, so the main parts must be replaced during operation for a certain period of time, and the shaft rotates to the left and right to supply the liquid while the set time stays, and to adjust the distribution ratio. There is a problem that a difference occurs in the ratio and the distribution ratio, so that the difference must always be corrected through the liquid in advance.

When the elliptical hole formed in the oblique direction shown in FIG. 5 (e) is adopted in the shape of a flow adjusting hole, the area of the portion where the first flow adjusting holes 135 and 136 and the second flow adjusting holes 145 and 146 communicate with each other is finely formed. It can be adjusted to more precisely control the rate of liquid supply.

In addition, as shown in FIG. 4, the second communication hole 143 and the second flow rate adjusting holes 145 and 146 formed in the rotating body 141 are integrally formed by continuously drilling the upper and lower parts of the rotating body 141. It is preferable to form or to form a plurality of intermittently intermittent upper and lower parts to the rotating body 141.

Here, the 'intermittently' the second flow rate adjusting holes (145, 146) are formed so that there is a portion that is broken when forming by machining, the shape (c), (d), (e) shown in FIG. do. When the second flow rate adjusting holes 145 and 146 are formed in the rotating body 141 so that there is an interrupted portion, the strength of the distribution control valve 130 may be reinforced.

The valve member 147 may operate to adjust an opening degree of the second flow rate adjusting holes 145 and 146 with respect to the first flow rate adjusting holes 135 and 136.

The valve member 147 is connected to one side of the rotating body 141 and serves to rotate the rotating body 141. The rotating body 141 rotates by the rotation of the valve member 147 and the rotating body 141. The second flow rate adjusting holes 145 and 146 may communicate with the first flow rate adjusting holes 135 and 136 of the fixed body 131 to distribute the liquid introduced into the upper space 117 into the lower space 119.

A chimney tray, one or more discharge means provided in the chimney tray and discharging the liquid descending from the top to the bottom, and an overflow wall 103 through which excess liquid that is not discharged through the discharge means can overflow. .

The shape of the overflow wall 103 may be variously configured as a flat plate, a cylinder, a square cylinder and the like.

Discharge means is to install a distribution control valve 130 for controlling the discharge of the liquid in the pipe (160). The chimney tray overflows the role of the first partition plate 113 in FIGS. 10 and 11, in which an excess of the liquid supplied to the first space may flow in, acting as a first space in which the discharge of liquid is controlled. The wall 103 replaces it. In addition, the side space where the liquid overflows the overflow wall 103 serves as the second space 121 in FIGS. 10 and 11.

The liquid dispensing device of the other embodiment shown in FIG. 13 is a case where it is provided in a column, and the distribution control valve 130 is attached to the chimney tray and overflows in the space separated by the separating wall 15 in the second column. The discharge pipe is formed to discharge into the space separated from the space from which the liquid beyond the wall 103 is directly discharged.

12 and 13, the liquid passing through the overflow wall 103 temporarily stays, while a pipe serving as a first pan and a seal pan 154 to enable continuous operation when the discharge pipe is blocked ( The second concept 155a is a relative concept with respect to 160.

In this case, the second column of the dividing wall distillation column is spatially divided by the dividing wall 15, and the number of the divided spaces in the second column = the number of overflow walls + the number of distribution control valves. For example, if there is one overflow wall and the number of distribution regulating valves is two, the divided space is three in total, two separated by the distribution regulating valve and one separated by the overflow wall.

The scope of the present invention is not limited to the embodiments described above, but is defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self evident.
