Exhaust gas filtering device

Abstract

A waste gas filtering device comprises a double filtering device composed of an exhaust pipe connected with a waste gas generating device, a water tank filtering device and a filter which are connected with the other end of the exhaust pipe, and the filter is in the middle of an outlet pipe which connects said water tank and filter.

Description

technical field [0001] The invention relates to an exhaust gas filtering device. Background technique [0002] Various existing exhaust gas devices are generally used to filter the exhaust gas produced by internal combustion engines on ships and vehicles or high-heat boilers used in power plants and factories. Dry filters are usually used, and the commonly used filtering method Such as: winding pipeline method, multi-layer paper or wire mesh method, mineral mesh layer method, etc. [0003] However, according to the above-mentioned exhaust gas filtering methods, there is a problem that the devices that filter the exhaust gas cannot reliably eliminate or filter the harmful substances contained in the exhaust gas produced by petrochemical products or coal after combustion. Direct discharge of gas to the outside will still pollute the atmosphere to a certain extent, destroying forests, building surfaces, human health, etc. In addition, the above exhaust gas filtering devices g...

Problems solved by technology

[0003] However, according to the above-mentioned exhaust gas filtering methods, there is a problem that the devices that filter the exhaust gas cannot reliably eliminate or filter the harmful substances contained in the exhaust gas produced by petrochemical products or coal after combustion. The direct discharge of gas to the outside will still pollute the atmosphere to a certain extent, destroying forests, building surfaces, human health, etc.

In addition, the above exhaust gas filtering devices generally have complex structures, large volumes, high costs, and narrow applicability, and are not suitable for filtering indoor air in ordinary families.
