Small-sized multilayer dust removal and desulfurization device

Abstract

The invention discloses a small-sized multilayer dust removal and desulfurization device which comprises a tank body, wherein a water bath is arranged at the inner bottom of the tank body; multiple spraying layers are arranged in the tank body; an air inlet pipe is arranged on the outer wall of the tank body; a spiral air compressor is arranged at one end of the air inlet pipe, and the other end of the air inlet pipe is communicated with an aerator pipe arranged at the bottom of the water bath to press dusty sulfur-containing flue gas into the water bath; a water inlet pipe is also arranged on the outer wall of the tank body; one end of the water inlet pipe is communicated with the bottom of the water bath, and the other end of the water inlet pipe is communicated with a lifting pump arranged on the outer wall of the tank body; the lifting pump is communicated with the spraying layers through a pipeline arranged on the outer wall of the tank body, so that an alkaline desulfurization solution in the water bath is delivered into the spraying layers for spraying operation through the lifting pump; a tapered flow guide cover is arranged at the top of the tank body; a ring-shaped exhaust opening is formed in the upper part of the tapered flow guide cover. The device is compact and simple in structure, relatively high in desulfurization efficiency and convenient in post-maintenance.

Description

technical field [0001] The invention belongs to a flue gas treatment device, in particular to a small multi-layer dust removal and desulfurization device. Background technique [0002] At this stage, coal fuel has become one of the indispensable energy sources in our country. Whether it is heating people's homes in winter or the daily production of some factories and enterprises, a large amount of coal needs to be burned. The combustion of coal will emit a large amount of flue gas into the air, which contains a large amount of dust and sulfur-containing oxides. If the untreated flue gas is directly discharged into the air, it will not only cause serious damage to the air and the environment. It will cause great damage to human respiratory system health. However, once sulfur-containing oxides contact with moisture in the air, acid rain will form, which will not only cause further pollution to the environment, but also corrode some buildings, posing a threat to people's lives...

AI Technical Summary

Problems solved by technology

The combustion of coal will emit a large amount of flue gas into the air, which contains a large amount of dust and sulfur-containing oxides. If the untreated flue gas is directly discharged into the air, it will not only cause serious damage to the air and the environment. Great damage, and will have an extremely adverse impact on the health of the human respiratory system

However, once sulfur-containing oxides contact with moisture in the air, acid rain will form, which will not only cause further pollution to the environment, but also corrode some buildings, posing a threat to people's lives and property

[0003] Therefore, with the continuous development of the economy, most of the dust removal and desulfurization methods are used for the flue gas after coal combustion in my country. A large amount of clean water is a waste of water resources
