technical field

The utility model relates to the technical field of waste gas treatment, in particular to a stereotyped waste gas electrostatic treatment device.

Background technique

In the prior art, electrostatic adsorption is generally used for the treatment of shaped waste gas. However, due to the large amount of moisture contained in the shaped waste gas, the adsorption capacity will decrease during the electrostatic adsorption process, so that the exhaust gas cannot be thoroughly treated.

Utility model content

The purpose of the present utility model is to provide a stereotyped exhaust gas electrostatic treatment device which is simple in structure and can treat exhaust gas more thoroughly and reliably in order to solve the deficiencies of the above-mentioned technologies.

The output end is provided with an air outlet pipe, a humidity detector is set in the No. 1 circulating pipe at the connection between the No. 1 circulating pipe and the connecting pipe, and the No. 1 circulating pipe and the connecting pipe at the connection between the No. The No. 1 control valve is provided. The No. 1 control valve on the No. 1 circulation pipe is located between the connecting pipe and the input end of the dryer. It also includes a No. 1 controller. The No. 1 controller is connected to a humidity detector and two No. 1 control valves. A No. 1 fan is arranged on the No. 1 circulating pipe at the output end of the dryer; the electrostatic generator in the treatment box is connected with the power supply outside the treatment box.

In the above technical solution, in the actual use process, the waste gas is first dewatered through the dryer, and the moisture is removed in the process of the exhaust gas passing through the dryer, and then the humidity is detected in the No. 1 circulating pipe, and the No. 1 controller is controlled in real time according to the detection data. No. 1 controller, when the detected humidity reaches the required requirements, the No. 1 control valve on the connecting pipe will be opened, the No. 1 control valve on the No. 1 circulating pipe will be closed, and the exhaust gas will enter the treatment box for electrostatic adsorption. When the humidity reaches the required requirements, the No. 1 control valve on the connecting pipe is closed, and the No. 1 control valve on the No. 1 circulating pipe is opened, and the exhaust gas is recirculated for drying treatment until the detected humidity reaches the standard and then electrostatic adsorption treatment is performed; here During the process, the No. 1 controller receives the signal in real time and controls the corresponding No. 1 control valve action, the stability of the system operation is higher, and the waste gas after dewatering is treated more thoroughly in the electrostatic adsorption process, ensuring the reliability of waste gas treatment. .

A No. 2 circulating pipe is arranged on the air outlet pipe. The No. 2 circulating pipe is connected to the input end of the treatment box. An exhaust gas indicator detector is arranged in the air outlet pipe where the air outlet pipe and No. 2 circulating pipe are connected. The No. 2 control valve is set on the air outlet pipe and No. 2 circulating pipe at the connection of the circulation pipe. The No. 2 control valve on the air outlet pipe is located at the outlet end of the air outlet pipe. The No. 2 controller is also connected to the exhaust gas indicator. The detector and two No. 2 control valves are provided with a No. 2 fan on the outlet pipe of the output end of the processing box. In the design of this structure, the indicator of the exhaust gas is detected in the exhaust pipe of the exhaust gas treated by electrostatic adsorption. If the indicator of the exhaust gas meets the requirements, the No. 2 control valve on the No. 2 circulating pipe is closed under the control of the No. 2 controller, and the output is discharged. The No. 2 control valve on the trachea is opened to discharge exhaust gas. When the exhaust gas index does not meet the requirements, the No. 2 control valve on the outlet pipe is closed, and the No. 2 control valve on the No. 2 circulation pipe is opened, and the exhaust gas enters the treatment again. The box is subjected to electrostatic adsorption treatment to ensure the standard output of exhaust gas. The exhaust gas indicator detector may be a device sensor for detecting a certain indicator in the exhaust gas, or a sum of sensors for comprehensively detecting multiple indicators in the exhaust gas.

The stereotyped exhaust gas electrostatic treatment device obtained by the utility model can effectively realize the electrostatic adsorption after drying the exhaust gas through reasonable structural design, thereby effectively improving the electrostatic adsorption performance of the exhaust gas and ensuring that the exhaust gas is discharged up to the standard.
