Also do not overcome at present the device of above-mentioned defect.
Summary of the invention
The purpose of this utility model is the defect that overcomes prior art, a kind of recycling that utilizes heat-treatment furnace fume afterheat to carry out fume afterheat is provided, fully improved heat recovery efficiency, improved energy utilization rate, reduce production costs, effectively reduce the heat-treatment furnace flue gas waste heat utilization device of exhaust emission simultaneously.
The utility model is realized in the following way:
A kind of heat-treatment furnace flue gas waste heat utilization device, comprise a heat-treatment furnace and chimney, it is characterized in that: on above-mentioned heat-treatment furnace, be connected with a fume pipe, the fume pipe other end is connected with successively pipe heat exchanger and heat exchange of heat pipe, between fume pipe and heat-treatment furnace, near heat-treatment furnace smoke outlet, MOD a is set, between the outlet of heat exchange of heat pipe and chimney, be connected with successively MOD b and air-introduced machine, between the outlet of above-mentioned pipe heat exchanger and chimney, by hot-flow flue, be connected;
On described heat exchange of heat pipe, be connected with air blast;
Described heat-treatment furnace is by least three series connection, and the exhanst gas outlet of every heat-treatment furnace is arranged a described MOD a;
Described fume pipe is the stainless steel circle flue of diameter 500mm, and rock wool heat-preservation felt or the super glass wool insulation quilt that 130mm is thick is set is incubated;
Described hot-flow flue is the carbon steel circle air channel of diameter 400mm, and rock wool heat-preservation felt or the super glass wool insulation quilt that 100mm is thick is set is incubated.
The utility model has following effect:
1) utilize heat-treatment furnace fume afterheat to carry out the recycling of fume afterheat, fully improved heat recovery efficiency, improved energy utilization rate, reduce production costs: the utility model comprises a heat-treatment furnace and chimney, it is characterized in that: on above-mentioned heat-treatment furnace, be connected with a fume pipe, the fume pipe other end is connected with pipe heat exchanger and heat exchange of heat pipe successively, between fume pipe and heat-treatment furnace, near heat-treatment furnace smoke outlet, MOD a is set, between the outlet of heat exchange of heat pipe and chimney, be connected with successively MOD b and air-introduced machine, between the outlet of above-mentioned pipe heat exchanger and chimney, by hot-flow flue, be connected, described fume pipe is connected with heat-treatment furnace, between arranges MOD a near heat-treatment furnace smoke outlet, and when heat-treatment furnace waste heat supply temperature reaches, when more than 400 ℃, MOD a opens automatically, open air-introduced machine, high-temperature flue gas discharges with fume pipe simultaneously, the fume pipe other end connects described pipe heat exchanger, flue gas is carried out to one-level heat exchange herein, and pipe heat exchanger absorbs a part of heat, and flue-gas temperature decreases, pipe heat exchanger is connected with heat exchange of heat pipe, and flue gas drains into heat exchange of heat pipe and carries out secondary heat exchange, and temperature continues to reduce, and when reaching discharge standard, MOD b opens, and residual air is discharged by free-standing chimney.Described air blast is inputted normal temperature air with certain air quantity to heat exchange of heat pipe, and air is absorbed heat, heated by heat exchange of heat pipe and pipe heat exchanger secondary respectively, when temperature rises to 200-250 ℃, by hot air duct, discharges, and is sent to and uses focus.The action of exhanst gas outlet MOD a is by heat-treatment furnace exhaust gas temperature signal controlling, when exhaust gas temperature during higher than 400 ℃ MOD a automatically open, when exhaust gas temperature during lower than 380 ℃ MOD a automatically close, utilize heat-treatment furnace fume afterheat heating cold wind, the hot-flow flue being incubated by band is delivered to by the mode of focus and is undertaken.
2) reduce production costs, effectively reduce exhaust emission simultaneously: because the operation of separate unit heat-treatment furnace is discontinuous, the heat-treatment furnace bootstrap system that the utility model provides is particularly useful for 3 above heat-treatment furnaces, to improve the utilization rate of heat exchanger.The exhanst gas outlet of every heat-treatment furnace is arranged a MOD a.Fume pipe is used the stainless steel circle flue of diameter 500mm, and rock wool heat-preservation felt or the super glass wool insulation quilt that 130mm is thick is set is incubated.Hot-flow flue is used the carbon steel circle air channel of diameter 400mm, and rock wool heat-preservation felt or the super glass wool insulation quilt that 100mm is thick is set is incubated.
3) the utility model is mainly to overcome that existing heat-treatment furnace waste heat directly discharges, wastes energy, the defect of contaminated environment, and a kind of heat-treatment furnace smoke waste heat utilization system is provided.As utilize the tail gas of heat-treatment furnace, after absolutely empty heat exchange, cause that mold pit dries sandbox and replace existing mould drying machine.Not only reduce energy consumption, avoided scene handling dryer back and forth simultaneously, easy-to-operate, and reduce environment and interfere, improve energy utilization rate, reduce production costs.
