Description

TECHNICAL FIELD

[0001] The utility model relates to waste gas treatment equipment technical field, especially a kind of waste gas treatment equipment for chemical production with convenient recycling. BACKGROUND

[0002] In the chemical production process, waste gas treatment is a crucial link, especially for the waste gas containing sulfur dioxide (SO2). Sulfur dioxide is a common atmospheric pollutant, which has potential harm to the environment and human health. Therefore, it has important environmental protection and economic value to effectively treat the waste gas containing sulfur dioxide and recycle the sulfur dioxide therein.

[0003] Currently, in chemical waste gas treatment, activated carbon adsorption is a commonly used method. Activated carbon can effectively adsorb sulfur dioxide and other pollutants in waste gas due to its large specific surface area and good adsorption performance. However, activated carbon adsorption method has a significant disadvantage, i.e. activated carbon needs to be replaced or regenerated after adsorption saturation, which not only increases the treatment cost, but also requires secondary recovery of sulfur dioxide adsorbed on activated carbon, which greatly increases the cost and efficiency of recycling. Therefore, a waste gas treatment equipment for chemical production with convenient recycling is needed to solve the above problems. SUMMARY

[0004] The utility model aims to solve at least one of the technical defects.

[0005] Therefore, one object of the utility model is to provide a waste gas treatment equipment for chemical production with convenient recycling to solve the problems mentioned in the background art and overcome the deficiencies in the prior art.

[0006] To achieve the above-mentioned object, an embodiment of the utility model provides a waste gas treatment equipment for chemical production with convenient recycling, which comprises a treatment box, a top plate is fixedly installed on the top surface of the treatment box by bolts, an assembly frame is fixedly installed on the inner wall of the treatment box by bolts, a plurality of V-shaped frames are fixedly connected to the inner wall of the assembly frame, one V-shaped zeolite molecular sieve is fixedly connected to the inner wall of each V-shaped frame, an air inlet pipe is fixedly connected to the outside of the treatment box, a gas guide frame is fixedly connected to the output end of the air inlet pipe, the gas guide frame is located inside the treatment box, a plurality of through holes are formed in the side surface of the gas guide frame, a water delivery pipe is fixedly connected to the side surface of the treatment box, a flow guide pipe is fixedly connected to the input end of the water delivery pipe, a plurality of spray heads are fixedly connected to the bottom surface of the water delivery pipe, and the plurality of spray heads correspond to the V-shaped zeolite molecular sieves in an up-down manner.

[0007] Preferably, the top surface of the top plate is fixedly connected with an exhaust pipe, the bottom surface of the processing box is fixedly connected with a collecting hopper, the bottom surface of the collecting hopper is fixedly connected with a recovery pipe, and one side of the recovery pipe is provided with a valve.

[0008] Preferably, the top surface of the collecting hopper is fixedly connected with a partition plate, and the partition plate and the processing box are fixedly connected with an arc-shaped flow guide plate corresponding to the through hole.

[0009] Preferably, the inner wall of the processing box is fixedly connected with a support frame through bolts, the top surface of the support frame is fixedly connected with a positioning pin, and the positioning pin is slidingly connected with the assembling frame.

[0010] Preferably, one end of the air guide frame away from the air inlet pipe is fixedly connected with the processing box, the top of the air guide frame is fixedly connected with an arc-shaped flow distribution plate corresponding to the V-shaped zeolite molecular sieve.

[0011] Preferably, the bottom surface of the top plate is fixedly connected with a limiting ring, and the limiting ring is fixedly connected with the water conveying pipe.

[0012] Compared with the prior art, the present application has the following advantages and beneficial effects:

[0013] When the chemical production waste gas needs to be treated, the waste gas can be discharged into the air guide frame through the air inlet pipe, and then the waste gas will flow to the arc-shaped flow guide plate through the through hole. The waste gas will float upward along the arc of the arc-shaped flow guide plate. At this time, the waste gas can be dispersed, so that the waste gas can fully contact with the V-shaped zeolite molecular sieve. The sulfur dioxide in the waste gas can be adsorbed by the V-shaped zeolite molecular sieve. The remaining waste gas flows into the next processing equipment through the exhaust pipe. During the waste gas treatment process, the water pump can be used to inject clean water into the water conveying pipe through the flow guide pipe. The clean water is sprayed onto the V-shaped zeolite molecular sieve through the spray head. At this time, the adsorbed sulfur dioxide will mix with the clean water to form a sulfurous acid solution, and flow to the collecting hopper for collection. The recycling of sulfur dioxide can be carried out at the same time as the waste gas treatment operation. The adsorbed sulfur dioxide does not need to be recovered again, which greatly reduces the cost of recycling. Moreover, the adsorption performance of the zeolite molecular sieve is less affected by humidity. Even in the wet condition, the adsorption efficiency can be maintained at a high level, and the effect of waste gas treatment will not be affected. BRIEF DESCRIPTION OF DRAWINGS
