Small-sized multilayer dust removal and desulfurization device

Abstract

The invention discloses a small multi-layer dust removal and desulfurization device, which comprises a tank body, a water bath is arranged at the bottom of the tank body, a multi-layer spray layer is arranged inside the tank body, an air inlet pipe is arranged on the outer wall of the tank body, and an air inlet pipe is arranged at one end of the air inlet pipe. There is a spiral air compressor, and the other end is connected with the aeration pipe installed at the bottom of the water bath to pressurize the dusty and sulfur-containing smoke into the water bath. There is also a water inlet pipe on the outer wall of the tank, and one end of the water inlet pipe is connected to the water bath. The bottom is connected, and the other end is connected with the lifting pump arranged on the outer wall of the tank. The lifting pump is connected with the spray layer through the pipe arranged on the outer wall of the tank, so that the alkaline desulfurization liquid in the water bath is sent to the spraying layer through the lifting pump. The spraying operation is carried out on the top of the tank body, and the top of the tank body is equipped with a conical diversion cover, and the upper part of the conical diversion cover is provided with a ring-shaped exhaust port; the device has a compact and simple structure, high desulfurization efficiency, and convenient maintenance in the later period.

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
