Boiler flue dust purification system

Abstract

The present invention discloses a boiler flue dust purification system, which comprises a flue exhaust pipeline connected with a steam boiler, a flue exhaust air blower, a water purification pool, and a bottom-free flue dust purification device positioned on the water purification pool, wherein the side surface on the lower end of the flue dust purification device is connected with the flue exhaust pipeline, the flue dust purification device is sequentially provided with a flue dust filtration device, a spraying device and a harmful gas filtration device from bottom to top, the top portion of the flue dust purification device is provided with a purified gas discharge port, the spraying device is connected with a submersible pump positioned in the water purification pool through a water supply pipe, the outer periphery of the submersible pump is provided with a filtration screen, and the water purification pool edge positioned on one side of the submersible pump is provided with a water supply valve. According to the present invention, the boiler flue dust purification system has characteristics of low investment cost, complete purification of flue dust, sulfur dioxide and other harmful gases in boiler waste gas, and broad development prospects.

Description

technical field [0001] The invention relates to a smoke and dust purification system, in particular to a small boiler smoke and dust purification system. Background technique [0002] At present, the living environment of human beings has been severely damaged, and the whole society is calling for the protection of the living environment and looking for countermeasures. There are many factors that destroy the living environment. Among them, the gas emission from boiler combustion has played a great role in the destruction of the environment, and the resulting boiler smoke purification equipment is also emerging in endlessly. [0003] The various soot purification equipment that have emerged in the past two decades are mainly suitable for the soot purification of large boilers. There are very few equipments for the soot purification of small steam and gas-water dual-purpose boilers, and generally have a single purification function. To achieve the effect of thorough purifica...

AI Technical Summary

Problems solved by technology

[0003]In the past two decades, all kinds of soot purification equipment are mainly suitable for the soot purification of large boilers, and for the soot purification of small steam and gas-water dual-purpose boilers There are very few equipments, and generally they all have a single purification function, which cannot achieve a thorough purification effect, because the smoke and dust of the boiler not only contains PM2.5 dust, but also contains harmful gases such as sulfur dioxide

The investment in large-scale smoke and dust purification equipment is very large, and the supporting small steam and gas-water dual-purpose boilers cannot be used at all
