Embodiment Construction

[0013] As shown in the figure, the harmful dust-laden gas is fed into the upper part of the tubular water film filter, and then discharged after being adsorbed by the vertically arranged filter tubes. , and become clean air exhaust. The filter tube is filled with flowing alkaline water, the alkaline water is pumped into the tube of the filter tube in the tubular water membrane filter, and the alkaline water in the tube is filtered through the filter screen to the filter tank and returned to the alkaline tank. The alkali water tank should maintain a certain alkali content and temperature, and there is a dosing port for adding alkali materials. The outlet of the pump is provided with a check valve and a regulating valve to prevent the backflow of lye and adjust the outlet flow. At the same time, there is also a pressure gauge, a water outlet and a water outlet, and the water outlet is communicated with the alkali water tank.

[0014] The upper part of the tubular water membran...

Abstract

The invention relates to a device for filtering sulfur dioxide with tubular aqueous film, and a relative method, wherein the lower part of buck groove has water pump verticall to the tubular filter tube; the lower part has filter network and sewage valve. And said method comprises: harmful gas enters into the filter tube, to be adsorbed and remove dust; the liquid adsorbed with harmful gas and dust flows inside the filter tubular tube, via buck groove-water pump-filter tube-filter network-filter pot-buck groove. The invention can filter harmful gas as sulfur dioxide, with high efficiency; better dedust effect, simple structure and stable operation.

Description

technical field [0001] The invention relates to an environmental protection device and a process method, in particular to a device for filtering harmful sulfur dioxide gas by using a tubular water film technology and a filtering process method thereof. Background technique [0002] At present, most of the filtration devices and methods for harmful sulfur dioxide gas use adsorption devices and methods, that is, the harmful gas is filtered and adsorbed by water to adsorb the harmful components in the gas, and then the adsorption liquid is processed in the next step. When the adsorption liquid contains a lot of dust and harmful substances, it requires a lot of equipment and multiple processes, such as precipitation treatment in the filter tank, water filtration devices, etc., especially after repeated treatment, so the investment in equipment is large, and the floor space is also very large. big. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to pr...
