Description

Technical Field

[0001] The present invention relates to the technical field of waste gas collection and treatment, and in particular to a waste gas collection and treatment device for the production of hazardous chemicals. Background Art

[0002] Waste gas treatment refers to the pre-treatment of waste gas generated in industrial sites and factory workshops before external discharge to meet the national standards for waste gas discharge. Generally, waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid and alkali waste gas treatment, odor waste gas treatment and air sterilization and purification. Different process technologies are used to recycle or remove and reduce harmful components in exhaust gas to protect the environment and purify the air, so that our environment is not polluted. The waste gas treatment devices currently used usually have a small gas-liquid contact area during the reaction, and the gas discharge position is fixed, which leads to a decrease in the liquid treatment efficiency near the discharge port and a poor treatment effect on the waste gas. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention provides a waste gas collection and treatment device for the production of hazardous chemicals, which solves the problem that the currently used waste gas treatment devices usually have a small gas-liquid contact area during the reaction and a fixed gas discharge position, resulting in a decrease in the liquid treatment efficiency near the discharge port and poor waste gas treatment effect.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a waste gas collection and treatment device for hazardous chemical production, specifically comprising: A processing box, the bottom of which is fixedly connected to a support frame, and one side of the processing box is connected to an air inlet pipe; An exhaust device, which is arranged inside the processing box, and one side of the exhaust device is connected to the air inlet pipe; An air outlet device, which is arranged on the top of the processing box, and the bottom of the air outlet device is connected to the inside of the processing box; The exhaust device comprises: An air disc, one side of the air disc is connected to an air outlet, and the side of the air disc away from the air outlet is connected to a connecting pipe; A fixed frame is arranged inside the gas disk, one side of the fixed frame is fixedly connected with an arc-shaped baffle, both ends of the arc-shaped baffle are fixedly connected with cleaning brushes, and an arc-shaped baffle is provided. When the gas disk rotates, the arc-shaped baffle can block the gas outlet located at the top of the gas disk, so that the gas disk can only be discharged through the gas outlet at the bottom, thereby avoiding the situation that the exhaust gas discharged from the upper gas outlet has a short contact time with the reaction liquid, resulting in an incomplete reaction; A rotating shaft, one end of which is fixedly connected to a side of the gas disc away from the connecting pipe, and the end of the rotating shaft away from the gas disc is fixedly connected to a driving shaft of a driving motor; The wind scoop is arranged on one side of the air disc, and the side surface of the wind scoop is fixedly connected to the air disc.

[0005] When in use, exhaust gas enters the connecting pipe inside the exhaust device through the air inlet, and enters the air disk through the connecting pipe. The exhaust gas inside the air disk is discharged into the treatment box through the air outlet. The exhaust gas reacts with the reaction liquid inside the treatment box to neutralize the harmful substances in the exhaust gas. When the air disk is discharging exhaust gas, the driving motor drives the air disk to rotate through the rotating shaft, and the air disk drives the air outlet to rotate.

When the air disk rotates, the filter screen can be cleaned by cleaning brushes at both ends of the arc baffle to avoid clogging of the filter screen. In addition, a plug and a tensioning spring are provided. Only when the air pressure inside the air disk reaches a certain level, the plug can be pushed to disengage from one end of the air outlet pipe, thereby preventing the reaction liquid inside the treatment box from entering the interior of the air disk through the air outlet pipe, thereby conveniently protecting the components inside the air disk.

The waste gas enters the connecting pipe inside the exhaust device through the air inlet, and enters the gas disk through the connecting pipe. The waste gas inside the gas disk is discharged into the treatment box through the air outlet. The waste gas reacts with the reaction liquid inside the treatment box to neutralize the harmful substances in the waste gas. When the gas disk discharges the waste gas, the driving motor drives the gas disk to rotate through the rotating shaft, and the gas disk drives the air outlet to rotate. The waste gas can be released from different areas inside the treatment box through the rotating air outlet, so that the waste gas can react with the reaction liquid in different areas, avoiding the situation where the local reaction liquid treats more waste gas and the treatment effect is reduced.

[0018] (5) This waste gas collection and treatment device for hazardous chemical production is provided with a gas storage device. When the waste gas reacts with the reaction liquid inside the treatment box and rises to the top of the inner wall of the treatment box, the gas on the top of the inner wall of the gas treatment box can be detected by a detector. When the detector detects that the gas reaches the emission standard, the electric telescopic rod shrinks, and the gas inside the treatment box enters the diverter pipe through the gas outlet. The gas pressure inside the diverter pipe gradually increases, pushing the piston to move in the direction of the electric telescopic rod. When the piston passes over the exhaust pipe, the gas inside the diverter pipe can be discharged through the exhaust pipe. The purity of the treated gas can be detected. The emission channel is opened only when the emission standard is reached.
