Air desulfurization and dust reduction equipment for underground engineering construction

Abstract

The invention belongs to the field of underground engineering construction and relates to air desulfurization and dust reduction equipment for underground engineering construction. The device comprises a gas inlet box and a desulfurization box fixedly connected to the upper end of the gas inlet box, the gas inlet box is fixedly communicated with the desulfurization box through a one-way communicating pipe, an exhaust pipe is fixedly communicated with the upper end of the desulfurization box, a thermoelectric power generation chip goes through the side wall of the exhaust pipe, a vertically-arranged partition plate is fixedly connected into the gas inlet box and divides the gas inlet box into an electrostatic cavity and a dust removal cavity, and a rotating shaft is rotatably connected to the inner top surface of the gas inlet box. According to the equipment, heat generated by a neutralization reaction can be converted into electric energy through the thermoelectric power generation chip, dust in the air is adsorbed through corona wires so that the dust falling effect is achieved, meanwhile, a small amount of dust carries negative charges to enter the desulfurization box along withthe air so that formation of large bubbles is restrained and therefore the contact area of the air and an alkaline solution is increased and the desulfurization effect of the air is greatly improved.

Description

technical field [0001] The invention belongs to the field of underground engineering construction, and in particular relates to an air desulfurization and dust reduction equipment for underground engineering construction. Background technique [0002] In order to effectively protect the ecological environment on the ground and develop and utilize underground space resources, more and more underground engineering buildings appear in people's production and life to meet people's various needs. [0003] During the construction of underground engineering, a large amount of acidic and harmful gases (such as SO 2 etc.) and dust, harmful gas and dust will not only cause harm to the health of construction workers, but also affect the normal operation of construction machinery, so it is often necessary to discharge harmful gas and dust through ventilation fans to ensure the safety of the construction environment With the extension of the tunnel or roadway and the increase of operati...

[0003] During the construction of underground engineering, a large amount of acidic and harmful gases (such as SO 2 etc.) and dust, harmful gas and dust will not only cause harm to the health of construction workers, but also affect the normal operation of construction machinery, so it is often necessary to discharge harmful gas and dust through ventilation fans to ensure the safety of the construction environment With the extension of tunnels or roadways and the increase of operating machinery, the difficulty of ventilation increases and the efficiency decreases, and the harmful gases and dust discharged will also pollute the external environment
