Inlet gas filter device and boiler provided with same

Abstract

The invention relates to the technical field of purifying, in particular to an inlet gas filter device and a boiler provided with same. The inlet gas filter device provided by the invention is arranged at an air inlet of a first object, and comprises a filter mechanism and a water curtain forming mechanism, wherein the filter mechanism is provided with a gas inlet, a gas outlet, and at least a primary filter screen arranged between the gas inlet and the gas outlet; the gas outlet communicates with the gas inlet; and the water curtain forming mechanism is used for forming a water curtain on each stage of the filter screen. According to the inlet gas filter device provided by the invention, the water curtain is formed on each stage of the filter screen through the water curtain forming mechanism, so that the water curtain on the filter screen is in sufficient contact with inlet air of a first object, adhesion and filtration on dust in inlet air is realized by utilizing the adhesion of water; circulating water continuously flushes the filter screen, so that the filter screen is kept transparent, and therefore, the filter screen is prevented from being blocked as a result of too much dust; and the device does not need to dismount for maintaining, and circulating water only needs to change, so that maintenance is relatively simple, and maintenance cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of purification, in particular to an intake air filter device and a boiler with the same. Background technique [0002] At present, with the development of the economy, boilers and other equipment are needed in the production process of many living and industrial fields. The fuels of boilers such as coal, gas, and fuel oil are mainly composed of hydrocarbons. A large amount of fresh air is needed in the process. For example, if 1 volume of natural gas is burned, 5-10 times more air needs to be added to make the combustion complete. Because of the presence of water molecules in the combustion products, it can be used under low temperature conditions. , the water molecules in the combustion products may condense on the heat exchanger, dust and other foreign matter in the air will be adsorbed on the condensed water, block the air circulation channel and even corrode the heat exchanger, and even affect whether t...
