Description

Technical Field

[0001] This application belongs to the field of chemical waste gas treatment technology, specifically a device for the safe treatment of chemical waste gas filtration. Background Technology

[0002] Chemical waste gas refers to complex gas mixtures generated during chemical production processes, typically containing harmful substances such as volatile organic compounds, sulfides, nitrogen oxides, and particulate matter. These waste gases mainly originate from incomplete combustion during chemical reactions, raw material volatilization, by-products, and equipment leaks. Due to their complex composition and high toxicity, direct emission of chemical waste gas without effective treatment can severely pollute the atmosphere, leading to air quality deterioration, acid rain formation, and exacerbation of the greenhouse effect. It also poses direct health risks, such as causing respiratory diseases, increasing the risk of cancer, or damaging the nervous system. Therefore, the treatment of chemical waste gas is a crucial task for the modern chemical industry, typically employing a combination of physical, chemical, and biological methods to ensure emissions meet standards.

[0003] As disclosed in CN218794901U, a safety treatment device for chemical waste gas filtration includes a filter box. Several limiting mechanisms are fixedly connected to the upper and lower front ends of the filter box. An exhaust pipe is fixedly connected to the middle left end of the filter box. Support feet are fixedly connected to the four corners of the lower end of the filter box. A water tank is fixedly connected to the middle lower end of the filter box. A gas supply mechanism is movably connected to the middle right end of the water tank. A water inlet pipe is fixedly connected to the upper right end of the water tank. A drain pipe is fixedly connected to the lower front end of the water tank. An air inlet pipe is fixedly connected to the middle left end of the water tank. This safety treatment device for chemical waste gas filtration, by setting limiting mechanisms and locking strips, facilitates the disassembly and replacement of the purification filter plates. By setting an air supply mechanism and a water tank, the filtration effect of the waste gas can be enhanced, making it suitable for widespread use.

[0004] However, in actual use, it was found that the traditional wet oxidation method involves introducing the gas to be treated into a pool and then allowing the gas to come into contact with the liquid. However, this method has limited capacity and processing speed. Therefore, it is necessary to switch to a treatment tower. However, the processing speed in the treatment tower is mainly controlled by the spraying speed of the treatment reagent. Therefore, a mechanical structure is needed to control the spraying speed of the reagent. Utility Model Content

[0005] The purpose of this application is to provide a safe treatment device for chemical waste gas filtration in order to solve the problem of controlling the spraying speed with a mechanical device mentioned above.

[0006] The technical solution adopted in this application is as follows: A safety treatment device for chemical waste gas filtration, wherein an air inlet pipe is fixedly inserted into the side surface of the treatment tower, an air outlet pipe is fixedly inserted into one end of the treatment tower opposite to the air inlet pipe, a spray pipe is fixedly inserted into the side surface of the treatment tower, a nozzle is fixedly connected to the side surface of the spray pipe, a flow control pipe is fixedly connected to one end of the spray pipe opposite to the nozzle, a plurality of supporting upright plates are fixedly connected to the side surface of the flow control pipe, a driving rod is slidably inserted into the side surface of the supporting upright plate, a plug-in plate is fixedly connected to the side surface of the driving rod, a plurality of limiting plates are fixedly connected to the side surface of the supporting upright plate, and a plurality of limiting holes are opened on the side surface of the limiting plates, and limiting bolts are slidably inserted into the limiting holes through the opened slots.

[0015] By adopting the above technical solution, the inlet metal mesh is used as a simple mesh component to prevent some solids in the treated gas from entering the treatment tower, and then the outlet pipe shut-off valve is used as the switch to control the outlet pipe.

[0016] In a preferred embodiment, a recovery tank is provided on the bottom surface of the processing tower, and a filter screen is provided on the inner side surface of the recovery tank.

[0017] By adopting the above technical solution, a recycling pool is used as a collection component to collect the treated liquid, while a filter screen is used as a filtration component to prevent a large amount of solid matter from entering below and causing blockage.

[0018] In a preferred embodiment, a discharge pipe is fixedly inserted into the bottom surface of the recycling pool, and a discharge pipe shut-off valve is provided on the side surface of the discharge pipe.

[0019] By adopting the above technical solution, the liquid is discharged through the discharge pipe and then controlled by the discharge pipe shut-off valve.

[0020] In a preferred embodiment, the outer side surface of the recycling pool is fixedly connected to multiple supports, and the side surface of the processing tower is provided with a cleaning port.

[0021] By adopting the above technical solution, the entire device is supported by a bracket to raise it, and then the cleaning port is used as a cleaning pipe for water injection and rinsing.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0025] In this application, the treatment tower serves as the main component for gas treatment. Gas enters the tower through the inlet pipe, undergoes treatment, and is ultimately discharged through the outlet pipe. The spray agent used to treat the waste gas is sprayed outwards through a flow control pipe, spray pipe, and nozzle. After spraying, the downward-facing treatment agent comes into contact with the upward-facing air to achieve treatment. A flow control assembly, consisting of a supporting vertical plate, a drive rod, a plug-in plate, a limiting plate, limiting holes, and limiting bolts, is used to control the spraying speed of the agent, allowing for controlled and sufficient contact time between the agent and the gas. The entire process is characterized by large gas throughput and high efficiency.
