Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and relates to a water washing and dust filtering box for incineration waste gas. Background Art

[0002] After the waste gas generated by the rotary kiln furnace for hazardous waste incineration treatment generally passes through the way of showering for filtration and neutralization treatment, that is, a spraying device is arranged at the top of the waste gas tower to shower the waste gas from bottom to top. The showering efficiency is relatively low. There is a situation that part of the waste gas is directly discharged without contacting the cleaning liquid, and the exhaust resistance is relatively large. Content of the Utility Model

[0003] The purpose of the utility model is to provide a water washing and dust filtering box for incineration waste gas aiming at the above problems existing in the prior art. The technical problem to be solved by the utility model is how to improve the water washing efficiency.

[0004] The purpose of the utility model can be realized by the following technical solutions: A water washing and dust filtering box for incineration waste gas, characterized in that it includes a box body, a runner, a cover plate, an air inlet pipe and an air outlet pipe. The cover plate is buckled at the opening of the box body. The circumference of the runner passes through the center of the cover plate. The runner is rotatably connected to the box body. The runner is driven by a reduction motor. A plurality of partition plates are evenly distributed in the circumferential direction on the runner. A plurality of water collecting notches are sealed on the partition plates. A water outlet hole is arranged in the middle of the water collecting notch. The water tank is filled with a showering liquid whose liquid level is below the axis of the runner. The air inlet pipe is located below the liquid level, and the air outlet pipe is located above the liquid level.

[0005] The waste gas enters the water tank through the air inlet pipe. After preliminary water washing, it enters the lower part of the cover plate above the liquid level. During the rotation of the runner, due to the existence of the water outlet holes on the runner, a water curtain can be formed after the partition plates on the runner exceed the liquid level. The water curtain performs secondary cleaning on the waste gas. At the same time, the dripping water curtain on the liquid surface can break and disperse the bubbles emerging from the water surface. In addition, part of the waste gas is re-entered into the water by the partition plates. Therefore, the waste gas can be washed with water and washed by the water curtain for multiple times. Compared with the traditional method, the exhaust resistance of the gas is relatively small. Brief Description of the Drawings

[0009] The following are specific embodiments of the present utility model and, in conjunction with the accompanying drawings, further describe the technical solutions of the present utility model. However, the present utility model is not limited to these embodiments.

[0010] As Figure 1 and Figure 2 shown, the water-washing and dust-filtering box for incineration waste gas includes a box body 1, a runner 2, a cover plate 3, an air inlet pipe 4, and an air outlet pipe 5. The cover plate 3 is buckled at the opening of the box body 1. The circumference of the runner 2 passes through the center of the cover plate 3. The runner 2 is rotatably connected to the box body 1. The runner 2 is driven by a reduction motor. A plurality of partition plates 6 are evenly distributed in the circumferential direction on the runner 2. A plurality of water-collecting notches 7 are sealed on the partition plates 6. A water outlet hole 8 is provided in the middle of the water-collecting notch 7. The water tank is filled with a flushing liquid whose liquid level is below the axis of the runner 2. The air inlet pipe 4 is located below the liquid level, and the air outlet pipe 5 is located above the liquid level.

[0011] The waste gas enters the water tank through the air inlet pipe 4 and enters the space below the cover plate 3 above the liquid level after preliminary water washing. During the rotation of the runner 2, due to the existence of the water outlet holes 8 on the runner 2, a water curtain can be formed after the partition plates 6 on the runner 2 exceed the liquid level. The water curtain performs secondary cleaning on the waste gas. At the same time, the dripping water curtain on the liquid level can break and disperse the bubbles emerging from the water surface. In addition, part of the waste gas is re-entrained into the water by the partition plates 6. Thus, the waste gas can be washed with water and the water curtain for multiple times. Compared with the traditional method, the resistance to gas emission is relatively small.

[0012] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
