Description

technical field [0001] The invention relates to the field of environmental protection, specifically a gas purification method and equipment thereof, more specifically a gas purification method and device thereof combining liquid flow cleaning and electrostatic adsorption. Background technique [0002] At present, gas purification is generally divided into wet and dry methods. Among them, the wet method is generally cleaned by water washing, spraying and flushing, while the dry method uses physical filtration combined with electrostatic adsorption. However, the cleaning efficiency of the traditional wet cleaning method is directly affected by the contact time and method of gas-liquid. Generally speaking, the high-pressure atomization method of gas-liquid contact has a high cleaning efficiency, but this method has high requirements for equipment and liquid loss. Large, easy to block, high maintenance costs and other disadvantages, in addition, in the case of fast gas flow rate...

However, the cleaning efficiency of the traditional wet cleaning method is directly affected by the contact time and method of gas-liquid. Generally speaking, the high-pressure atomization method of gas-liquid contact has a high cleaning efficiency, but this method has high requirements for equipment and liquid loss. Large, easy to block, high maintenance costs and other disadvantages, in addition, in the case of fast gas flow rate, it will cause secondary pollution

At present, electrostatic adsorption technology is divided into two categories: wet method and dry method. The wet method mainly includes tube type, honeycomb type, and casing type, and the dry method mainly includes plate type, tube curtain type and double-zone type. Influenced by factors such as the flow rate of the purified gas, the concentration of the dust content, and the accumulation of the electrostatic dust collection plate, the phenomenon of plate voids and gas leakage occurs, which reduces the purification efficiency and causes secondary pollution. Moreover, the equipment is large in size and occupies a large area. High equipment investment cost
