Problems solved by technology

This type of equipment has a large internal space. In order to ensure the effect of water mist, it must be equipped with a lot of conical nozzles. Small, easy to block, resulting in heavy maintenance work; this type of device has a large air resistance, and a higher pressure fan must be selected, so generally the fan power is larger and the cost is higher; because the water and air contact surface is smaller, the treatment effect is better. Poor; the equipment occupies a large area, the cost is high, and the amount of waste water generated is large and many other problems

Abstract

The invention discloses a circulatory rinsing type waste gas treatment system which comprises a plurality of waste gas treatment devices and a PLC (Programmable Logic Controller) control cabinet, wherein the waste gas treatment devices conduct remote opening-closing control through the PLC control cabinet. Each waste gas treatment device comprises a pre-filtering assembly, a rinsing assembly, a draught fan and an exhausting assembly which are connected through pipes in sequence. Each exhausting assembly comprises two outlets, wherein one is used for exhausting gases, and the other one is connected with the corresponding pre-filtering assembly. Each exhausting assembly comprises a sensor for detecting the gas content, a control unit of a strobe outlet and an opening-closing unit of two outlets. The output end of each sensor is connected with the corresponding control unit which is connected with the corresponding opening-closing unit. The circulatory rinsing type waste gas treatment system controls the waste gas treatment devices through the PLC control cabinet in a remote control way, is safe and reliable and can further improve the quality of exhausted gases due to the provided circulatory detection function.

Description

technical field [0001] The invention relates to a circulating water washing waste gas treatment system. Background technique [0002] Exhaust gas purification mainly refers to the treatment of industrial waste gas such as dust particles, flue gas, odorous gas, and toxic and harmful gases generated in industrial places. Common exhaust gas purification includes factory smoke and dust exhaust gas purification, workshop dust exhaust gas purification, organic waste gas purification, Exhaust gas odor purification, acid-base exhaust gas purification, chemical waste gas purification, etc. At present, the more commonly used exhaust gas treatment devices are exhaust gas treatment towers. [0003] The water absorption method is a relatively common waste gas treatment method at present. The equipment used in this method is relatively simple, the use cost is low, and it is suitable for treating gaseous and liquid pollutants. Traditional water absorption equipment generally adopts a hori...
