Abstract
Novel mobile ventilation equipment for tunnels is characterized in that a small-size axial-flow ventilator, two liquid tanks and a powder reagent box are mounted on a mobile light load diesel truck. Harmful gas sucked by the small-size ventilator is delivered into three degradation boxes step by step through air ducts, the primary degradation box contains water mixed with foaming agent and sizing agent in a certain quantity, the mixture of the water, the foaming agent and the sizing agent is sprayed to the harmful gas through a water pump and is mainly used for removing dust in the harmful gas, the secondary degradation box contains chemical reagent which is sprayed for degradingCO2, the tertiary degradation box contains powder materials containing molecular sieves for absorbing CO, and finally fresh airflow is exhausted from an air outlet pipe. The mobile ventilation equipment has the advantages of high maneuverability, absorption efficiency and practicability, and is suitable to be used as main ventilation equipment for short-distance tunnels shorter than 300m, and is also suitable to be used as auxiliary ventilation equipment for long-distance tunnels longer than 3000m.
Description
Technical field:
The present invention designs a kind of ventilation equipment, is specially adapted to the traffic tunnel construction field, also is applicable to the mine working construction field that no gas is gushed out.
Background technology:
At present, during the tunnel piercing behind the drilling and blasting, during loading vehicles transportation ballast and during the whitewashing of combined bolting and shotcrete, can produce amounts of dust; Behind the drill bursting construction explosive charge and during the vehicle operating of shipment quarrel, can produce carbon monoxide (CO), carbon dioxide (CO
2), nitric oxide (NO), nitrogen dioxide (NO
2) wait pernicious gas, for growing, because the increase of flowing resistance and the variation of elevation apart from the tunnel.Existing method of ventilation can't in time be discharged less than 300m short distance and the long requirement of satisfying construction apart from the tunnel pernicious gas of big 3000m.Apart from the increasing of tunnel, construction environment, drafting efficiency, air quality are proposed increasingly high requirement, and existing method of ventilation can not satisfy the requirement of constructing tunnel along with long.
Summary of the invention:
The purpose of this invention is to provide a kind of movably, power is little, use cost is low, the ventilation equipment of the pernicious gas of directly degrading, to satisfy the quality requirement of tunneling operation to the cleaning with fresh air of tunneling construction work plane.
The present invention constitutes like this: it comprises chemical agent 10, the adsorption box chemical agent of placing in the chemical agent 6 placed in light-duty load-carrying lorry 15, small-sized axial fan 2, first order degraded case 20, second level degraded case 21, adsorption box 22, first order degraded case air chimney 3, second level degraded case air chimney 7, adsorption box air chimney 11, first order degraded case water pump 4, second level degraded case 8 and the first order degraded box body, the second level degraded box body 12.It is characterized in that being in small-sized axial fan 2, first order degraded case 20, the second level degraded case 8 that the spray chemical agent reacts pernicious gas and chemical agent and degrades, the adsorption box 22 devices NaY molecular sieve that contains Cu salt further purifies air then; Small-sized axial fan 2 is driven by small diesel engine 14, and the pernicious gas that small-sized axial fan 2 sucks is through first order degraded case air chimney 3 input first order degraded case degraded dust and NO
X, once more through second level degraded case airduct 7 entering second level degraded case 21 degraded CO
2, get into adsorption box 22 through the adsorption box air chimney then and absorb CO, after exhaust duct 13 is discharged fresh distinguished and admirable; Pernicious gas that sucks and dust enter first order degraded case 20 through first order degraded case air chimney 3, in first order degraded case vent passageway, shower nozzle 5 are installed, and the liquid of spray is to implement through the first order degraded case 20 outer pump of installing 4 suction liquid 6; Gas through first order degraded case 20 is degraded case airduct 7 entering second level degraded case 21 through the second level; And the fountain head of in second level degraded case airduct 7, installing 9, the liquid reagent of ejection is implemented through the second level degraded case 21 outer jet pump 8 suction liquid reagents 10 of installing; After Cu salt NaY molecular sieve 12 in the adsorption box 22 reacted with pernicious gas, Cu salt NaY molecular sieve adopted the method for heating to reuse.
Owing to adopted technique scheme, the present invention to adopt brand-new harmful gas removing technology; It changes draft type the mode of direct degraded into, compares with traditional tunnel piercing draft type, and the advantage of following several respects is arranged:
1) mobility strong, the efficient of degraded pernicious gas is high
Degeneration system of the present invention is installed on the jubilee wagen, and the work to the flue dust district of directly going after development end is blown out sucks pernicious gas with small-sized ventilation fan, through the chemical agent reaction chamber, effectively reduces the pernicious gas pollution range.Pernicious gas and dust for loader, haulage vehicle in the shipment rock ballast process produce can carry out movable type degraded pernicious gas and dust through moving this equipment; For the grit that the lining cutting whitewashing produces, only need first order degraded work of the present invention just can accomplish the effect of catching dirt, depositing dust.
2) easy to use, running cost is low
When ventilation fan of the present invention ventilated, only needing regularly annotates in fluid box contained the aqueous solution of chemical agent, adds NaY molecular sieve reagent in the powder case; Regularly add thermal reduction; Regularly get rid of mud.Since the each 2～3kg that only needs of the chemical agent that adds in the aqueous solution, 3～5 yuan/kg of reagent, and powder case reagent can add thermal reduction and reuse, and therefore adopts running cost of the present invention lower.
The present invention and prior art are relatively; The present invention has mobility strong, drafting efficiency is high, use cost is low; Be applicable to less than 300m short distance tunnel as main ventilation equipment; Also be applicable to length greater than 3000m apart from the tunnel as secondary ventilation equipment, and be applicable to that national defence chamber driving flue dust does not go out the hole, the advantage that the hidden construction in cavern needs.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention.
The specific embodiment:
Embodiments of the invention: in the present embodiment; Small-sized axial fan 2 is fixed on the light-duty load-carrying lorry 15 through cradling piece 1; Its power supply adopts miniature diesel generator 14 to drive; Connect through first order degraded case air chimney 3 with first order degraded case 20, first order degraded case air chimney 3 is fixed on the casing of first order degraded case 20, and the pernicious gas of suction and dust enter first order degraded case 20 through one-level degraded case air chimney 3; In first order degraded case vent passageway, shower nozzle 5 is installed, the liquid of spray is implemented through the first order degraded case 20 outer pump of installing 4 suction liquid 6; Gas through first order degraded case 20 is degraded case air chimney 7 entering second level degraded case 21 through the second level; And in second level degraded case air chimney 7, fountain head 9 is installed; The liquid reagent of ejection is implemented through the second level degraded case 21 outer jet pump of installing 8 suction reagent 10; The electric energy of pump 4, jet pump 8 is provided by miniature diesel generator 14, and the mud that produces in the first order degraded case 20 is washed by pipe valve 17 after blowdown pipe valve 16 is discharged; The mud that produces in the second level degraded case 21 is washed after middle blowdown pipe valve 18 is discharged by middle pipe valve 19.The gas that second level degraded case 21 is discharged gets into adsorption boxes 22 through adsorption box air chimney 11, and after reative cell 12 reactions of immersing the NaY molecular sieve of Cu salt through the 3rd road again purified, clean air was sent among the tunnel through exhaust duct 13.
