The waste gas treatment and heat supply system of the color steel plate production line comprises a surface coating furnace (1), a bottom coating furnace (2), a waste gas pre-heater (3), an incinerator (4) and a pretreatment liquid heating device (5), and is characterized in that exhaust ports of the surface coating furnace (1) and exhaust ports of the bottom coating furnace (2) are communicated to the waste gas pre-heater (3) through waste gas exhaust pipelines, a gas outlet of the waste gas pre-heater (3) is communicated to the incinerator (4), a gas outlet of the incinerator (4) is communicated to gas inlets of the surface coating furnace (1) and gas inlets of the bottom coating furnace (2) through tail gas exhaust pipelines, and part of tail gas of the incinerator (4) passes through the pretreatment liquid heating device (5) through a tail gas exhaust branch pipeline and then is led to a smoke exhaust fan (6), a coating furnace (7) and a hot air drying device (8). The waste gas treatment and heat supply system of the color steel plate production line has the advantages of energy conservation and emission reduction.
Description
Technical field
The utility model relates to a kind of exhaust-gas treatment heating system of color steel sheet production line, belongs to color steel printing technology.
Background technology
Color steel sheet is that a kind of building material just growing up in recent years is both at home and abroad decorated and household electrical appliances plate, of many uses.The including of production line of tradition color steel sheet is coated with stove, face is coated with stove, primary coat stove, hot blast drying device, tail gas burning furnace, pre-treatment liquid heater etc., traditional change is coated with stove, face is coated with stove, primary coat stove and hot blast drying device needs the independent hot blast that feeds, face is coated with stove, primary coat stove and tail gas burning furnace meeting discharging waste gas, and pre-treatment liquid heater needs the independent heat energy that feeds to heat.Because equipment is various, between various device, do not have systematic energy recycling, cause energy consumption larger, improve the pollution of enterprise's production cost and environment.The exhaust-gas treatment heating system of color steel sheet production line of therefore seeking a kind of energy-saving and emission-reduction is particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of exhaust-gas treatment heating system of color steel sheet production line of energy-saving and emission-reduction is provided.
The purpose of this utility model is achieved in that
A kind of exhaust-gas treatment heating system of color steel sheet production line, it comprises that face is coated with stove, primary coat stove, heat economizer, incinerator and pre-treatment liquid heater, the exhaust outlet that it is characterized in that described painting stove and primary coat stove leads to heat economizer by exhaust emission pipe, incinerator is led in the gas outlet of described heat economizer, the air inlet that face is coated with stove and primary coat stove is led to by exhaust emission pipeline in the gas outlet of described incinerator, some leads to respectively smoke exhaust fan by an exhaust emissions branch pipe(tube) after by pre-treatment liquid heater the tail gas of incinerator, change and be coated with stove and hot blast drying device.Between described exhaust emission pipe and exhaust emission pipeline, be connected with a safety corridor, on safety corridor, be provided with a motor-driven valve.
Compared with prior art, the beneficial effects of the utility model are:
The exhaust-gas treatment heating system of the utility model color steel sheet production line has advantages of energy-saving and emission-reduction, has not only protected environment, has reduced enterprise's production cost simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the exhaust-gas treatment heating system of the utility model color steel sheet production line.
Wherein:
Face is coated with stove 1, primary coat stove 2, heat economizer 3, incinerator 4, pre-treatment liquid heater 5, smoke exhaust fan 6, changes painting stove 7, hot blast drying device 8.
The specific embodiment
Referring to Fig. 1, the exhaust-gas treatment heating system of a kind of color steel sheet production line that the utility model relates to, it comprises that face is coated with stove 1, primary coat stove 2, heat economizer 3, incinerator 4 and pre-treatment liquid heater 5, the exhaust outlet of described painting stove 1 and primary coat stove 2 leads to heat economizer 3 by exhaust emission pipe (in Fig. 1, solid line represents), on described exhaust emission pipe, be provided with exhaust gas fan, incinerator 4 is led in the gas outlet of described heat economizer 3, the air inlet that face is coated with stove 1 and primary coat stove 2 is led to by exhaust emission pipeline (in Fig. 1, dotted line represents) in the gas outlet of described incinerator 4, at air inlet, place is provided with circulating fan, between exhaust emission pipe and exhaust emission pipeline, be connected with a safety corridor, on safety corridor, be provided with a motor-driven valve, when the hot-gas temperature in exhaust emission pipeline arrives certain value, motor-driven valve is opened, cryogenic gas in exhaust emission pipeline does not directly enter exhaust emission pipeline by heat economizer 3 and incinerator 4, high-temperature gas is wherein carried out to temperature neutralization, thereby protective surface is coated with stove 1 and primary coat stove 2, the tail gas of incinerator 4 some by an exhaust emissions branch pipe(tube) by the rear smoke exhaust fan 6 that leads to respectively of pre-treatment liquid heater 5, change and be coated with stove 7 and hot blast drying device 8.
Claims (2)
1. the exhaust-gas treatment heating system of a color steel sheet production line, it comprises that face is coated with stove (1), primary coat stove (2), heat economizer (3), incinerator (4) and pre-treatment liquid heater (5), the exhaust outlet that it is characterized in that described painting stove (1) and primary coat stove (2) leads to heat economizer (3) by exhaust emission pipe, incinerator (4) is led in the gas outlet of described heat economizer (3), the air inlet that face is coated with stove (1) and primary coat stove (2) is led to by exhaust emission pipeline in the gas outlet of described incinerator (4), some leads to respectively smoke exhaust fan (6) by an exhaust emissions branch pipe(tube) after by pre-treatment liquid heater (5) tail gas of incinerator (4), change and be coated with stove (7) and hot blast drying device (8).
