Problems solved by technology

[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

Embodiment 1

[0021] Such as Figure 1-2 As shown, an air desulfurization and dust reduction equipment for underground engineering construction includes an air intake box 1 and a desulfurization box 2 fixedly connected to the upper end of the air intake box 1, and the air intake box 1 is fixedly communicated with the desulfurization box 2 through a one-way communication pipe 3, The one-way communication pipe 3 only allows the air in the air intake box 1 to enter the desulfurization box 2, and the upper end of the desulfurization box 2 is fixedly connected with an exhaust pipe 4, and a thermoelectric power generation chip 5 is installed on the side wall of the exhaust pipe 4 to further The air box 1 is fixedly connected with a vertical partition 6, and the partition 6 divides the air intake box 1 into an electrostatic chamber 7 and a dust removal chamber 8, wherein the bottom of the electrostatic chamber 7 is fixedly connected with an air intake pipe 14, and the dust removal chamber 8 The lo...

Embodiment 2

[0027] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is: the corona wire 12 is fixedly sleeved with a permanent magnet ring 16, and the side wall of the dust removal chamber 8 is fixedly connected to a horizontally arranged bar magnet 17, and the bar magnet The two ends magnetic poles of 17 are opposite.

[0028] In this embodiment, when the turntable 10 drives the corona wire 12 to rotate, the permanent magnetic ring 16 on the corona wire 12 is close to the two ends of the bar magnet 17 in turn, and under the action of the magnetic force, the bar magnet 17 is opposite to the corona. The permanent magnet ring 16 on the wire 12 produces periodically changing attractive and repulsive forces, which cause the corona wire 12 to vibrate slightly, which is beneficial to the capture and adsorption of the dust in the air by the corona wire 12 passing through the current, and at the same time, the corona wire 12 can capture and absorb dust in the air...

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...
