In addition, the second outer case 200 may have a receiving space formed therein to receive the purifying unit 300, which will be described later.

Referring to FIGS. 1 and 3, a purifier 300 may be provided inside the second outer case 200. The purifier 300 is configured to neutralize the acidic gas (hereinafter referred to as acidic gas) generated from the hazardous material when the operator handles the hazardous material in the first outer case 100 by receiving the acidic gas from the first outer case 100 .

Referring to FIGS. 1 and 2, a first duct 400 for moving the acid gas from the first outer case 100 to the purifier 300 is provided. One side of the first duct 400 passes through the upper surface of the first outer case 100 and is connected to the space S to communicate therewith. The other side of the first duct 400 is connected to the inside of the purifier 300 through the rear side of the purifier 300. Thus, the acidic gas existing in the first outer case 100 can be moved to the purifying unit 300 through the first duct 400.

Referring to FIGS. 1 and 2, a second duct 500 is spaced apart from the first duct 400 by a predetermined distance. One end of the second duct 500 is inserted through the second outer case 200 and is connected to the inner space of the purifier 300. At this time, the other side of the second duct 500 is preferably exposed to the outside of the building. Therefore, the neutralized acid gas in the purifier 300 can be discharged to the outside.

Referring to FIG. 2, the other side of the second duct 500 may be exposed to the outside, and the other duct may be provided with a separate blowing unit 600 for providing a suction force to the first outer case 100.

In addition, the blowing unit 600 may be configured as a ventilator provided outside the building.

Referring to FIG. 3, the purifier 300 can retrieve the purifier 300 from the second outer case 200 when the purifier 300 is replaced or major parts inside the purifier 300 are old and need to be repaired or replaced. The bottom surface of the purifier 300 may be provided with a sliding part 700 or a driving wheel for drawing the purifier 300 from the second outer case 200. The purifier 300 Is easily detached / drawn out from the second outer case 200, which is advantageous in that it is easy to manage.

Referring to FIGS. 3 and 4, the first and second ducts 400 and 500 are connected to the connection part for connecting the first and second ducts 400 and 500 to the purifying part 300, And a gap adjusting unit 900 for tightening and fastening the unit 300. When the purifier 300 is moved from the second outer case 200 to the original position to replace or repair the purifier 300, To guide the movement of the purifier 300 to move to the position of the purifier 300. [ That is, the interval adjusting unit 900 is provided on both sides of the purifying unit 300 and is connected to the first and second ducts 400 and 500 when the drawn purge unit 300 is again drawn into the second outer case 200 The connection portion of the purifier 300 can be fastened. In addition, since the gap adjusting unit 900 fixes the first and second ducts 400 and 500, it is possible to prevent a phenomenon such as a widening of the connecting portion due to an external shock or vibration.

4 to 8, the purifying unit 300 includes a first reaction unit 310, a first nozzle 320, a first receiving unit 330, and a first dehumidifying unit 350.

First, the first reaction part 310 receives the acidic gas from the test case 100 and has a hollow shape to hold the acidic gas in a predetermined space. It is preferable that the first reaction part 310 is located below the experimental case 100. An inlet 311 communicating with the inside of the first reaction part 310 is formed at one side of the first reaction part 310 in the back direction to receive acid gas from the experimental case 100. The inlet 311 is connected to the other side of the suction duct 200 and can receive acid gas from the inner case 310.

In addition, a partition wall 313 is provided in the first reaction part 310 to guide the movement path of the acid gas. Since the partition wall 313 is provided in the first reaction part 310, the first reaction part 310 can be partitioned into a movement path 312 for moving the acid gas.

The nozzle 320 can spray the neutralizing liquid in a predetermined radius in the form of a mist in order to neutralize the acidic gas contained in the first reaction part 310. The nozzle 320 can be located on the upper side of the first reaction part 310 desirable.

Referring to FIG. 7, the first receptacle 330 is located at the lower end of the inner case 310, that is, the lower end of the lower end of the first reaction part 330. The neutralizing liquid in which the neutralizing agent is dissolved is accommodated in the first accommodating portion 330 and the neutralizing liquid accommodated in the first accommodating portion 330 may be supplied to the nozzle 320.

At this time, the nozzle 320 and the first accommodating part 330 are connected to each other through a separate connection pipe 321. One side of the connection pipe 321 passes through one side of the first accommodating portion 330 and the other side is connected to the nozzle 320 so that the neutralizing liquid can be supplied to the nozzle 320. At this time, it is preferable that a pump P is formed in the connection pipe 321 to supply the neutralizing liquid to the nozzle 320.

A plurality of inlets 340 communicating with the hollow interior space of the first reaction part 310 are formed at the upper end of the first accommodating part 330 in the first accommodating part 330. This is because the residual neutralizing liquid injected from the first reaction part 310 flows into the inlet 340 again so that the neutralizing liquid can be recirculated. It is preferable that the inlet port 340 extends vertically and the lower end of the inlet port 340 is submerged to a predetermined depth in the neutralized liquid received in the first receiving portion 330. Accordingly, it is possible to prevent the acidic gas contained in the first reaction part 310 from flowing into the first accommodating part 330.

8, the upper end of the first accommodating portion 330 has a shape inclined at a predetermined angle? In the direction of the inlet 340. This is to allow the remaining neutralized liquid of the first reaction part 310 to flow smoothly into the inlet 340. There is a further advantage that the dissolving rate of the neutralizing agent can be improved as the residual neutralizing liquid flowing into the inlet 340 drops to the first containing portion 330.

6 and 9, the first dehumidifying part 350 receives the neutralized acid gas in the first reaction part 310 to separate the moisture or residual neutralizing liquid contained in the acid gas, (400) to remove acidic gas from which moisture has been removed. That is, the first dehumidifying part 350 communicated with the first reaction part 310 receives the acidic gas to one side and transfers the acidic gas to the exhaust duct 400 through the outlet 351 provided at the other side. At this time, the first dehumidifier 350 is provided with a first desiccant 352 for separating moisture or residual neutralizing liquid from the acidic gas, and the first dehumidifier 350 is divided into the inside A partition 350-1 may be provided. Therefore, the acid gas moves in a 'U' shape.

The first desiccant 352 is composed of a plurality of meshes of fibers, and the acidic gas passes through the first desiccant 352, so that the moisture containing the acidic gas in the plurality of meshes and the remaining neutralized liquid are formed into a liquid do.

The first dehumidifying part 350 is provided at the upper end of the first receiving part 330 with the lower end opened and when the remaining neutralizing liquid formed in the first desiccant 352 falls downward due to gravity, (340) along the sloping top of the second chamber (330).

Referring to FIGS. 4 and 5, the partition 313 of the first reaction unit 310 includes a first partition 313-1 and a second partition 313-2. The first partition 313-1 extends from one side to the other side of the inner side of the first reaction part 310 with respect to the plane. At this time, it is preferable that the end of the first partition 313-1 is spaced apart from the inner surface of the first reaction part 310 by a predetermined distance so that the acidic gas can be moved. The second barrier ribs 313-2 are spaced apart from the first barrier ribs 313-1 by a predetermined distance and extend in a direction symmetrical to the first barrier ribs 313-1. As a result, the distance of the moving path 312 can be increased, and the acid gas flowing into the inlet 311 moves in an 'S' character. Accordingly, the time for which the acid gas stays in the first reaction unit 310 is increased, and the neutralization ratio can be improved.

Referring to FIGS. 4 and 8, a plurality of first filling parts 360 are spaced apart from each other by a predetermined distance in the movement path 312. In the first filling part 360, a plurality of air rings may be provided to improve the contact ratio between the acidic gas and the neutralizing liquid. This makes it possible to reduce the moving speed of the acidic gas passing through the moving passage 312.

That is, when the acid gas passing through the first filling part 360 enters the small holes of the plurality of air pellets filled in the first filling part 360, the instantaneous moving speed increases but the first filling part 360 passes through The moving speed of the acid gas is remarkably reduced. Since a plurality of first filling parts 360 are provided and a plurality of spaced spaces are arranged between the first filling parts 360, the above-mentioned phenomenon is repeated, and the contact efficiency between the acid gas and the neutralizing liquid can be improved .

The first nozzles 320 are disposed in the spaced-apart spaces between the first filling parts 360 to spray the neutralizing liquid. At this time, the jetting direction of the first nozzle 320 may be the direction of the first filling part 360, or the direction opposite to the traveling path of the acid gas.

When an experiment is performed using an aqueous solution of hydrochloric acid having a high concentration in the interior of the first outer case 100, acid gas mixed with hydrochloric acid and other aqueous solution to be evaporated flows through the first duct 100, (400) and moves to the purifier (300). At this time, the acid gas is strongly acidic.

The neutralizing liquid dissolved in calcium hydroxide (Ca (OH) 2) provided at the lower end of the purifying part 300 reacts with the acidic gas to generate a precipitate of water (2H 2 O) and calcium chloride (CaCl 2) Is neutralized.

Referring to FIG. 7, a cooling part 370 for cooling the neutralizing liquid is provided in the first accommodating part 330. When the neutralizing agent is dissolved in the neutralizing liquid, the temperature of the neutralizing liquid is increased. The calcium hydroxide used as the neutralizing agent is preferably lowered in the temperature of the solution to be dissolved, since the dissolution rate of the calcium hydroxide is remarkably decreased when the temperature of the solution to be dissolved is high. In order to solve this problem, the first accommodating part 330 is provided with a cooling part 370 for lowering the temperature of the neutralizing liquid.

The cooling unit 370 is provided between the plurality of cooling plates 371 and the cooling plate 371 having a predetermined thickness and spaced apart from each other by a predetermined distance in the vertical direction to cool the cooling plate 371 A compressor 373 connected to the refrigerant moving pipe 372 and the refrigerant moving pipe 372, and a heat exchanger 374. The cooling plate 371 is formed in a wide plate shape so that heat exchange with the neutralizing liquid can be smoothly performed. The refrigerant is accommodated in the refrigerant moving pipe 372. The refrigerant is converted into gas and the refrigerant converted into gas is transferred to the compressor 373 and converted into liquid. Thereafter, the refrigerant moves to the heat exchanger 374 and is cooled, and the cooled refrigerant moves to the refrigerant pipe 371 again. As the process is repeatedly circulated, the neutralizing liquid can always be maintained at a constant temperature (0 to 20 ° C). The cooling unit 370 corresponds to a cooling method used in a general refrigerator.

Referring to FIG. 9, the second duct 500 is provided with a second dehumidifying part 380. The second dehumidifying part 380 is provided for the purpose of removing residual moisture of the acidified gas discharged from the first dehumidifying part 350. That is, the second dehumidifier 380 removes the remaining moisture that is not removed yet, so that only the completely dried air is discharged.

The second dehumidifying part 380 includes a second desiccant 381 through which the acid gas passes and a third desiccant 383 separated from the second desiccant 381 by a predetermined distance. The second desiccant 381 and the third desiccant 383 are made of the same material and structure as those of the first desiccant 351.

The rotation bar 930 penetrates through each support base 920 and extends in the same direction as the longitudinal direction of the bracket 910. At this time, the rotation bar 930 is rotatable to one side or the other side of the support base 920, and one end of the rotation bar 930 can be inserted into the coupling hole 210 and fastened. Finally, the control lever 940 is formed at the other end of the rotation bar 930 and is used as a kind of handle that allows the user to easily rotate the rotation bar 930.

Accordingly, when the control lever 940 is operated to rotate the rotation bar 930 to be inserted into the fastening hole 210, the inner case 310 moves backward to press the sealing ring 800, The gap between the outlet 312 and the first duct 400 and the second duct 500 becomes narrow.

The acidic gas purifying apparatus according to the present invention has a structure in which the acid gas is leaked into the fine gaps between the first and second ducts 400 and 500 and the purifying unit 300, It is possible to prevent the phenomenon of threatening safety and to easily draw the purifier from the second outer case, which is an advantage of easy maintenance.

Hereinafter, another embodiment of the present invention will be described in detail.

Referring to FIG. 12, the sliding portion 700 includes a rail 710, a driving wheel 720, and a stopper 730. The rail 710 is seated on the inner bottom surface of the second outer frame 200. At this time, the end of the rail 710, that is, the direction in which the rail 710 extends extends in a direction in which the purifier 300 moves (draws). The drive wheel 720 is formed on the lower surface of the purifier 300. It is preferable that a plurality of driving wheels 720 are provided to support the purifier 300. Thereafter, a stopper 730 is provided in front of or behind the rail 710. The stopper 730 may be formed at the front and rear of the rail 710, respectively, or at the same time to control the forward and backward movement of the purifier 300. The stopper 730 formed at the front of the rail 710 prevents the purge unit 300 from being completely drawn out from the second outer frame 200 and the stopper 730 formed at the rear prevents the purge unit 300 from being drawn It is possible to prevent collision with the rear side wall of the second outer frame 200.
