The salt bath furnace waste gas treatment device is simple in structure; because the volume space of the closed chamber is far larger than that of an absorption tower, the manufacturing cost of the whole device is very low, and the device is suitable for being used in actual conditions of medium-sized and small enterprises, can be constructed in each enterprise and is convenient to use.
Description
Technical field
The present invention relates to a kind for the treatment of apparatus, particularly relate to a kind of salt bath furnace emission-control equipment.
Background technology
Tool industry high-speed steel tool is the general salt bath furnace quench hot that adopts in quenching, and the salt bath furnace that heat treatment is used is mainly with barium chloride, and sodium chloride is working media.They can distribute a large amount of chlorine under high temperature fused state, the salt fog that hydrogen chloride gas and barium chloride etc. form, and these salt fog medium-sized and small enterprises one photographed in chimney stack straight through air blast and were discharged in air again, and this can cause environmental pollution on a large scale.Environmental requirement is now more and more higher, do not allow salt fog arbitrarily to discharge, the method that the administration way of environmental protection factory generally adopts neutralization to absorb, by blower fan waste gas suck out deliver in smog absorption tower be attached to absorption tower in the aqueous slkali on packing layer surface contact neutralization reaction occur, make the harmful substance in smog deposit to get off to be pooled in solution pool, in the atmosphere of finally purified gas being clapped, go.
Factory generally uses smoke stack emission waste gas now, do not meet environmental requirement, certainly need to improve, the salt fog absorption tower pipeline multiple footprint that environmental protection factory is used is large, the salt fog tower volume that can play neutralization reaction is little, neutralization is not ideal, and equipment cost is also high, and medium-sized and small enterprises generally can not afford.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of salt bath furnace emission-control equipment, it is simple in structure, because secret room volume space is much larger than absorption tower, the manufacturing expense of whole setting is very low, be applicable to the actual conditions of medium-sized and small enterprises, each enterprise afford to make, and uses also easily, and cost is also low.
The present invention solves above-mentioned technical problem by following technical proposals: a kind of salt bath furnace emission-control equipment, it is characterized in that, it comprises aspiration channel, induced-draught fan, watch window, shower, exhaust outlet, spray valve, sewage draining valve, blowdown ditch, aqueous slkali pond, spray pump, door, slag blocking wall, confined chamber, the centre of aspiration channel is connected with induced-draught fan, one end of aspiration channel is stretched in aqueous slkali pond, watch window is positioned at the top of induced-draught fan and is arranged on confined chamber, exhaust outlet is positioned at the top of confined chamber, a part for shower is arranged in confined chamber, another part of shower is positioned at outside confined chamber, spray valve, sewage draining valve is all arranged on shower, blowdown ditch, spray pump is all connected with shower, slag blocking wall is positioned at aqueous slkali pond, door is positioned at aqueous slkali pond and is arranged on the bottom of confined chamber.
Preferably, the other end of described aspiration channel is connected with a salt bath furnace.
Positive progressive effect of the present invention is: the present invention is simple in structure, and because secret room volume space is much larger than absorption tower, the manufacturing expense of whole setting is very low, is applicable to the actual conditions of medium-sized and small enterprises, and each enterprise afford to make, and uses also easily, and cost is also low.
Brief description of the drawings
Fig. 1 is the structural representation of salt bath furnace emission-control equipment of the present invention.
Detailed description of the invention
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
As shown in Figure 1, salt bath furnace emission-control equipment of the present invention comprises aspiration channel 2, induced-draught fan 3, watch window 4, shower 5, exhaust outlet 6, spray valve 7, sewage draining valve 8, blowdown ditch 9, aqueous slkali pond 10, spray pump 11, door 12, slag blocking wall 13, confined chamber 14, the centre of aspiration channel 2 is connected with induced-draught fan 3, one end of aspiration channel 2 is stretched in aqueous slkali pond 10, watch window 4 is positioned at the top of induced-draught fan 3 and is arranged on confined chamber 14, exhaust outlet 6 is positioned at the top of confined chamber 14, a part for shower 5 is arranged in confined chamber, another part of shower 5 is positioned at outside confined chamber, spray valve 7, sewage draining valve 8 is all arranged on shower 5, blowdown ditch 9, spray pump 11 is all connected with shower 5, slag blocking wall 13 is positioned at aqueous slkali pond 10, door 12 is positioned at aqueous slkali pond 10 and is arranged on the bottom of confined chamber 14.The other end of aspiration channel 2 is connected with a salt bath furnace 1.
The poisonous salt fog that the present invention produces salt bath furnace is thrown in an aqueous slkali pond of containing aqueous slkali by induced-draught fan sucking-off by side-draught hood and pipeline, above aqueous slkali pond, change a confined chamber that has 50m3 space, in confined chamber, load onto part shower, aqueous slkali in aqueous slkali pond (containing the caustic soda of 2% concentration) can be atomised to space by spray pump, when being flushed in aqueous slkali pond at a high speed under the effect of salt fog at induced-draught fan.A part and aqueous slkali directly react, remaining gas with very low speed upwards floating be atomised to airborne aqueous slkali and fully contact generation neutralization reaction.For extending the service life of confined chamber, interior walls is all coated anticorrosive paint, and will there be sealing effectiveness in room simultaneously, and gas can not leak.Staff is led to aqueous slkali pond outside closed chamber, and outdoor section separates with wall, opens the door in bottom, forms " U " type tube effect inside and outside in the time that water level pushes up higher than door, in wall, is separated and forms sealing by water.Spray pump dress gets final product safety operation without, can observe at any time again water level height, detects alkaline concentration.While needing scarfing cinder, spray pump arranges solution in aqueous slkali pond into Bilge.Personnel enter and clear up from bottom door.
The salt fog that salt bath furnace produces, is thrown in the aqueous slkali pond of containing aqueous slkali through exhaust duct waste gas by induced-draught fan sucking-off by air-suction duct.Open spray valve, shut sewage draining valve, spray pump is started working.Aqueous slkali by valve enter shower the atomization of liquid be enclosed in backroom waste gas and fully contact generation neutralization reaction.Chlorine deposits in aqueous slkali pond together with other impurity with water for neutral salt with hydrogen chloride gas neutralization.Treated waste gas is discharged in atmosphere and goes through exhaust outlet.Slag blocking wall is used for preventing that waste residue from being sucked by spray pump.Watch window observable shower working condition.While using a period of time to clear up waste residue, shut spray valve, open sewage draining valve pump and start working, the aqueous slkali in aqueous slkali pond enters after the discharge totally of blowdown ditch, enters cleaning aqueous slkali pond sweep waste residue from door.In work, to note often observing water level height, will add water in time lower than warning line.Use PH detection paper alkaline concentration simultaneously, while being neutrality, will add in time caustic soda.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect to solution of the present invention further describe; institute is understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
