Safe and reliable circulating water washing type waste gas treatment system

Abstract

The invention discloses a safe and reliable circulating water washing type waste gas treatment system which comprises an upper computer, a plurality of PLC (Programmable Logic Controller) cabinets and a plurality of waste gas treatment devices, wherein the upper computer is connected with the PLC cabinets; the PLC cabinets are connected with the waste gas treatment devices; each waste gas treatment device comprises a pre-filtering component, a water washing component, an induced draft fan and an exhaust component that are sequentially connected by pipelines; each exhaust component comprises a sensor for detecting a gas content, a control unit gating outlets and opening and closing units of the two outlets; the sensors are arranged at inlets of the exhaust components; output ends of the sensors are connected with the control units; and the control units are connected with the opening and closing units. According to the system, the upper computer controls the PLC cabinets, the PLC cabinets remotely control the waste gas treatment devices, and the system is safe and reliable, and can remotely control the organic waste gas treatment devices to improve efficiency.

Description

technical field [0001] The invention relates to a safe and reliable 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 gener...

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
