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

The invention discloses a circulating water-washing type waste gas treatment device. The circulating water-washing type waste gas treatment device comprises a pre-filter assembly, a water-washing assembly, a draught fan and a gas exhausting assembly which are connected in sequence through a pipeline, wherein the gas exhausting assembly comprises two outlets, one outlet is used for exhausting gas, and the other outlet is connected with the pre-filter assembly; an air supplementing valve is arranged between the pre-filter assembly and the water-washing assembly; the gas exhausting assembly comprises at least one sensor for detecting the gas content, a gating outlet control unit and an opening-closing unit for two outlets; the sensor is arranged at an inlet of the gas exhausting assembly; the output end of the sensor is connected with the control unit; the control unit is connected with the opening-closing unit. The circulating water-washing type waste gas treatment device adopts a circulating detection function to perform circulating when the waste gas emission does not reach the standard, so that the quality of the exhausted gas is further improved.
Description
technical field [0001] The invention relates to a circulating water washing waste gas treatment device. 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...
