Description
technical field:
The present invention relates to a kind of technical field of heat treatment, particularly relate to the purifier of N2shielded heat-treatment stove furnace lining atmosphere.
background technology:
the N2shielded heat-treatment stove of prior art mostly adopts organic hydrocarbon compounds fuel as protection gas raw material in order to protective atmosphere, in stove, cracking process is a kind of reversible balance cracking reaction, oxygenatedchemicals water can be produced in cracking process, because water can have oxidation to part in stove, thus unfavorable factor is played to the surface cleaning of part, a large amount of moisture is contained in furnace lining in addition when masonry heater seals, moisture after also having blowing out in air is absorbed by furnace lining, large quantity of moisture can be evaporated to furnace lining outer wall through high temperature and be discharged in stove in stove, very large to part oxidation hazards, thus affect surface quality of workpieces.
summary of the invention:
Technical problem to be solved by this invention is, provides a kind of stove to seal atmosphere purification device, from withdrawing moisture in furnace lining, and can purify furnace air and recycle, thus both having solved washy problem in stove, also reaching the object of energy-conserving and environment-protective.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of stove envelope atmosphere purification device, be provided with heat-treatment furnace, described heat-treatment furnace includes shell and furnace lining.
Conveniently bleed from furnace lining, further, described furnace lining is provided with multiple bleeding point.
In order to can out waste gas be facilitated, further, the side of described furnace lining arranges waste gas burning mouth.
In order to the object of purification can be reached, further, described bleeding point arranges a set of purifier.Described purifier includes many one end and is connected to exhaust tube on bleeding point.
In order to the cooling of extracting air can be facilitated, further, the other end of described exhaust tube is connected on condenser.
Conveniently cooled water discharge, more further, the bottom of described condenser is fixedly connected with fluid reservoir.
In order to gas can be made in inner loop, more further, the side of described fluid reservoir is fixedly attached to the side of aspiration pump, and the opposite side of described aspiration pump is fixedly attached to waste gas burning mouth.
In order to the flow of taken out waste gas can be monitored in real time, more further, between described aspiration pump and waste gas burning mouth, be also provided with flowmeter.
In order to conveniently control the flow of air, further, between described flowmeter and aspiration pump, be provided with control valve, the top of described condenser is provided with discharge outlet, and bottom is provided with water inlet, and described water inlet and discharge outlet are respectively arranged with control valve.
Compared with prior art, usefulness of the present invention is: provide a kind of stove to seal atmosphere purification device, from withdrawing moisture in furnace lining, and can purify furnace air and recycle, thus both solved washy problem in stove, also reach the object of energy-conserving and environment-protective.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is front view of the present invention.
In figure: 1, heat-treatment furnace; 2, shell; 3, furnace lining; 4, bleeding point; 5, waste gas burning mouth; 6, purifier; 7, exhaust tube; 8, condenser; 9, fluid reservoir; 10, aspiration pump; 11, flowmeter; 12, control valve; 13, discharge outlet; 14, water inlet.
detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments: a kind of stove envelope atmosphere purification device according to Fig. 1, be provided with heat-treatment furnace 1, described heat-treatment furnace 1 includes shell 2 and furnace lining 3, described furnace lining 3 is provided with multiple bleeding point 4, the side of described furnace lining 3 arranges waste gas burning mouth 5, described bleeding point 4 arranges a set of purifier 6, described purifier 6 includes many one end and is connected to exhaust tube 7 on bleeding point 4, the other end of described exhaust tube 7 is connected on condenser 8, the bottom of described condenser 8 is fixedly connected with fluid reservoir 9, the side of described fluid reservoir 9 is fixedly attached to the side of aspiration pump 10, the opposite side of described aspiration pump 10 is fixedly attached to waste gas burning mouth 5, flowmeter 11 is also provided with between described aspiration pump 10 and waste gas burning mouth 5, control valve 12 is provided with between described flowmeter 11 and aspiration pump 10, the top of described condenser 8 is provided with discharge outlet 13, bottom is provided with water inlet 14, described water inlet 14 is respectively arranged with control valve 12 with discharge outlet 13.
During use, aspiration pump 10 starts, by the steam in stove and air from sucking-off bleeding point 4, in stove, steam and air are sucked out from bleeding point 4, enter into inside condenser 8 through exhaust tube 7, by condenser 8 by steam and air setting, the water produced after condensation enters into fluid reservoir 9 from the bottom of condenser 8, then enter into control valve 12 and flowmeter 11 through aspiration pump 10 through condensed air to enter into waste gas burning mouth 5 and burn, burning creates fiery curtain and is sealed by waste gas burning mouth 5, and then outside malaria is blocked, by this purifier, not only the air in stove and steam are carried out purifying and drying, also form fiery curtain by burnt gas, the air of outside is blocked, both air had been purified, reach again the object of energy-conserving and environment-protective.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
