Description

UPWARD-OPEN AND HORIZONTAL TYPE WET SCRUBBER TOWER [0002]

A wet scrubbing column (or scrubber) is a device for collecting solid or liquid particles suspended in an exhaust gas using a liquid.

Such a wet scrubbing tower is a spray type in which a cleaning liquid is sprayed to collect dust or contaminants contained in exhaust gas, a water jet type which uses depressurization by injection of high-pressure water, a centrifugal centrifugal force Inertial system that collects particles by inertia and inertia, Filtration system that collects particles by filter medium, Thin film system that flows liquid on collecting surface and collects dust, Mechanical system that injects liquid by rotating blades, And a packed column type in which the liquid is sprayed from the liquid.

In addition, the wet scrubbing tower can be divided into a vertical type and a horizontal type. The vertical type is to vertically erect the housing and to remove the contaminants contained in the exhaust gas by the cleaning liquid which is sprayed on the upper part while the exhaust gas flowing into the lower part moves upward. On the other hand, a horizontally-shaped housing is horizontally installed, and contaminants contained in the exhaust gas are removed by a cleaning liquid that is sprayed on the upper portion of the exhaust gas flowing from one side of the housing.

Although the present invention relates to a packed tower type washing tower and a horizontal type washing tower in a horizontal type wet cleaning tower, a vertical type wet cleaning tower or a vertical type wet cleaning tower has been mainly used in the past. For example, FIG. 11 shows an example of a vertical-charge tower wet cleaning tower according to the prior art. As shown in the drawing, the conventional wet scrubbing tower has a gas inlet 11 formed in a lower portion of a vertical housing 10, a gas outlet 12 formed in an upper portion thereof, and a gas inlet 11 The contaminated exhaust gas flows into the filling layer during the upward movement of the exhaust gas, and the harmful gas component and the malodorous component are removed from the filling solution layer and then discharged through the gas outlet 12 at the upper part. To this end, at least one packing layer 80 is formed in the housing 10, and a rinse solution inflow pipe 61 for supplying rinse solution is installed.

However, in the wet cleaning tower according to the related art, since the filling layer 80 is installed in the upper part of the housing 10, it is very difficult to replace the filling material. That is, when the cleaning tower is operated for a long time, if the contaminants are adhered to the surface of the packing material filled in the packing material layer 80, the pores become narrow and the gas and the cleaning liquid flow smoothly and the treatment efficiency becomes poor. Therefore, the conventional wet scrubbing column requires a manhole for accessing the filler layer 80. Therefore, it is necessary for the person to carry out the work of removing the filler through the manhole and filling the filler again There is a problem that much time and cost are used accordingly.

In addition, since the wet cleaning tower according to the related art has a vertically installed housing and a high height, it is difficult to install the wet cleaning tower in a room with a low ceiling. Particularly, when a hoist is installed on the upper part of the vertical cleaning tower to mechanize the maintenance, a working space of the hoist must be sufficiently secured. However, the conventional vertical wet cleaning tower has a limitation in lowering the height thereof.

A gas inlet chamber 33, a cleaning chamber 34, and a baffle chamber 35 are formed in this order in the cleaning tank 3 in the horizontal direction. In the spray tank 5, a minute mist 54 is formed.

The cleaning chamber 34 is located at an upper portion of the water receiving chamber 24 and a charging box 63 filled with a plurality of fillers 61 is installed therein. The filling material 61 serves to extend the contact time between the gas and the cleaning liquid and to increase the contact area to improve the gas purification efficiency. As shown in FIGS. 8 to 10, the filling material 61 according to the present invention is formed of a plate in which a plurality of circular rods 61a are arranged at regular intervals. At this time, a certain distance is formed between the circular rods 61a, and a plurality of projections 61b are formed to protrude from the outer circumferential surface of the circular rod 61a. The filling cell 61 is filled with a plastic square frame having a predetermined size. Then, a plurality of charging cells 62 are filled in a square box to form a filling box 63. [

The baffle chamber 35 is located at the upper portion of the water receiving chamber 24, and a plurality of baffle plates 71 are vertically installed therein. The obstruction plate 71 interrupts the flow of gas to remove water contained in the gas. A lattice plate 21 or a perforated plate is installed on the bottom of the washing chamber 34 and the bellows chamber 35 so as to be connected to the receiving chamber 24. A plurality of through holes are formed in the grid plate 21 and the perforated plate so that the cleaning liquid can freely fall.

The partition wall (54) is located above the cleaning chamber (34). The jetting header 81 is horizontally installed inside the jetting section 54. A plurality of injection nozzles 82 are provided at the lower end of the injection header 81. A cleaning liquid is jetted from the jetting header 81 through the opening 101 between the branch chamber 54 and the cleaning chamber 34 so that the cleaning liquid injected from the jetting header 81 flows into the cleaning chamber 34, Of the filling material 82.

Then, a cleaning liquid circulation pipe 6 for supplying a cleaning liquid is connected between the water supply chamber 24 and the mist separator 54. A jetting header 81 provided at the branching part 54 is connected to the tip of the cleaning liquid circulation pipe 6. A circulation pump (11) connected to the water receiving chamber (24) is provided at the lower end of the washing liquid circulating pipe (6).

A cleaning header 91 is installed horizontally on the bottom of the inlet chamber 33, which is a gas. A plurality of jet nozzles 92 are installed behind the cleaning header 91. The washing header 91 is provided with a washing water circulation pipe 8 for supplying a washing liquid connected to the washing liquid circulating pipe 6.
