Technical field

The present invention relates to gas purifying equipment technical field more particularly to a kind of underground engineering construction dust and sour gas Body self-purging filter plant.

Background technique

Domestic city development is just increasingly faced with: soil is in short supply, congested in traffic, environmental pollution, energy shortage, fragility of taking precautions against natural calamities The problems such as.City spatial colonization mode just turns to " solid " from " ground ", more and more municipal works and civil engineering selection Develop to underground, and has created large number of Large Underground Structure object.

During underground construction, a large amount of dust and sour gas (such as SO can be generated₂), and the air in underground construction environment It circulating unsmooth, it will aggravation machinery causes fuel burning insufficient because of anoxic, and content of acid gas increases in the tail gas of discharge, To reduce machine power, the health of operator is compromised, shortens mechanical service life；Existing technology In, air is passed through in alkaline solution by most wind collecting machine, and the mode for reacting sour gas with alkaline solution removes dust and acid Property gas, and the work of blower also need fuel burning drive, can not only consume the oxygen in underground construction environment, cause to lack The problem of oxygen, occurs, while can also generate a large amount of sour gas, increases the burden of acid gas purifying.

The air being discharged after being purified by alkaline solution, the water that portable alkaline solution evaporation generates at high operating temperatures Vapour, and contain a large amount of alkali in steam, secondary pollution easily is caused to air, and equally cause damages to the health of construction personnel.

For this purpose, we have proposed a kind of underground engineering construction dust and sour gas self-purging filter plants.

Summary of the invention

The purpose of the present invention is to solve dust in underground engineering construction environment in the prior art and sour gas to be difficult to The problem of purification, and propose it is a kind of can self-purging dust and sour gas underground engineering construction dust and sour gas Self-purging filter plant.

To achieve the goals above, present invention employs following technical solutions: a kind of underground engineering construction dust and acid Property gas self-purging filter plant, including inlet cylinder, dust cleaning case and purifying box, the inlet cylinder and dust cleaning case fixed peace side by side Mounted in the bottom of purifying box, air bag and memory spring, the gas have been respectively fixedly connected on the inner sidewall of the inlet cylinder two sides Capsule is fixedly connected with memory spring, and fixation is communicated with one-way intake pipe and one-way exhaust pipe, the list on the side wall of the air bag Run through the side wall of inlet cylinder to air intake duct and extend to outside inlet cylinder and be arranged, the one-way exhaust pipe, which extends in dust cleaning case, to be set It sets；

It is rotatably connected to Dust-proof rotary drum on the inner sidewall of the dust cleaning case, is offered on the side wall of the Dust-proof rotary drum multiple The inner sidewall in the dust filtering hole being placed equidistant with, the dust cleaning case is equipped with dedusting mechanism, and one end of the Dust-proof rotary drum is coaxially fixed Fan is installed, the other end fixation of the Dust-proof rotary drum is communicated with unidirectional gas-guide tube, and the other end of the unidirectional gas-guide tube prolongs Setting in purifying box is extended to, the upper end of the purifying box is equipped with venthole.

In above-mentioned underground engineering construction dust and sour gas self-purging filter plant, the side of the inlet cylinder The heat release hole of multiple annular array settings is offered on wall.

In above-mentioned underground engineering construction dust and sour gas self-purging filter plant, set in the purifying box There are two heat conductive rods, the lower end of the heat conductive rod sequentially passes through purifying box and inlet cylinder and extends to setting in inlet cylinder.

In above-mentioned underground engineering construction dust and sour gas self-purging filter plant, the bottom of the dust cleaning case Portion is hinged with hermatic door.

In above-mentioned underground engineering construction dust and sour gas self-purging filter plant, the one-way exhaust pipe Outlet end and the central axes of fan be in same level.

In above-mentioned underground engineering construction dust and sour gas self-purging filter plant, the purifying box it is upper Side is equipped with lime set case, and the upper end of the venthole is fixed to be communicated with two escape pipes, and two escape pipes are in about lime set case The inverted L-shaped pipe of center symmetric setting is arranged, and the outlet end of two escape pipes is connected to the two sides of lime set case respectively, described solidifying The lime set web plate being vertically arranged is fixedly connected on the inner sidewall of liquid case, the upper end of the lime set case is equipped with delivery pipe, described solidifying The lower end fixation of liquid case is communicated with the return pipe being connected to purifying box.

Compared with prior art, the present invention has the advantages that

1, in the present invention, purifying box is provided with alkaline solution, and neutralization reaction, reaction can occur with sour gas for alkaline solution Equation is SO₂+ 2NaOH=Na₂SO₃+H₂O, alkaline solution the sour gas in air can be dissolved and react generate salt and Water, avoid sour gas in the construction environment of underground machinery and staff cause damages.

2, in the present invention, when room temperature, memory spring be in elongation state, alkaline solution and sour gas generation in purifying box Neutralization reaction generates a large amount of heat, is heated by heat conductive rod to memory spring, then memory spring shortens, and pulls air bag swollen It is swollen, it lower end of the memory spring far from purifying box and is radiated at this time by heat release hole, then the memory spring for restoring room temperature extends again, Air bag is compressed, and so on, periodically compression and stretching repeatedly is carried out to air bag, then air bag constantly will with dust and The air of sour gas is discharged into dust cleaning case.

3, in the present invention, air enters in dust cleaning case, and the dust-filtering in air can be prevented dust from entering by Dust-proof rotary drum In purifying box, alkaline solution is polluted, to guarantee the effect of alkaline solution purification of acidic gas.

4, in the present invention, the air of one-way exhaust pipe blowout blows to fan, and fan rotation is driven then to drive Dust-proof rotary drum Rotation, then can be struck off the dust that Dust-proof rotary drum surface is adhered to by dedusting mechanism, prevent Dust-proof rotary drum from being caused by dust covering Blocking.

5, it in the present invention, is discharged simultaneously from two escape pipes by the purified air of purifying box, two escape pipes go out Mouth end is met at lime set case, then two strands of air-flows converge in lime set case and mutually clash, then the air pressure of river outlet increases, and is promoted The liquefying power of gas, the then alkaline solution carried in air liquefy at lime set web plate, and by being back to by return pipe In purifying box, the waste of alkaline solution is avoided, while avoiding alkaline solution from being mingled with and the body of staff is caused in air Harm.
