Abstract
The utility model discloses a tail gas recycling device of an open-fire heating thermal treatment furnace, which belongs to the technical field of tail gas treatment of an open-fire furnace. The tail gas recycling device comprises a smoke hood which is arranged at a gas exhaust end of a furnace body, wherein the smoke hood is provided with a heat exchange component, heat exchange medium flows in the heat exchange component, heat exchange is carried out between the heat exchange component and a heated body through a pipeline, and the pipeline is connected with a heat exchange medium conveying pump and a heat exchange medium storage box. According to the tail gas recycling device of the open-fire heating thermal treatment furnace, disclosed by the utility model, the heat exchange medium in the heat exchange medium storage box can be pumped into the heat exchange component through a pump, a heating component in the heat exchange component can be heated through the heat exchange, the heat exchange medium which is heated can be used for other heat supply devices, the heat exchange medium which is cooled can flow back to the heat exchange medium storage box, not only is the structure simple and the implementation easy, but also the heat of tail gas of the open-fire furnace is reasonably utilized, energy-saving and emission-reducing effects are realized, and the production cost is reduced to a certain degree.
Description
Technical field
The utility model belongs to direct-fired heater vent gas treatment technical field, relates in particular to a kind of open firing heat-treatment furnace tail gas recycling device.
Background technology
At present, the mode of direct-fired heater exhaust emissions, adopt directly discharged more, and exist and cause heat not recycle like this, to resource, be a kind of waste, be unfavorable for energy-saving and emission-reduction.
The utility model content
The purpose of this utility model is to provide a kind of open firing heat-treatment furnace tail gas recycling device, it collects recycling for the tail gas by direct-fired heater, to solve direct-fired heater tail gas in prior art, directly discharge wasting energy of existing, be unfavorable for the problem of energy-saving and emission-reduction.
For reaching this purpose, the utility model by the following technical solutions:
A kind of open firing heat-treatment furnace tail gas recycling device, it comprises the petticoat pipe that is installed on the body of heater exhaust end, wherein, on described petticoat pipe, be provided with heat exchanger components, fluid interchange medium in described heat exchanger components, and described heat exchanger components carries out heat exchange by ducted heat transferring medium and heated object, on described pipeline, is connected with heat transferring medium delivery pump and heat transferring medium storage bin.
Especially, described heat exchanger components is heat exchange coil, and described heat exchange coil is close to the petticoat pipe setting.
Especially, described heat transferring medium is any of heat-exchanging water or conduction oil.
Especially, described heat transferring medium delivery pump is horizontal pump.
The beneficial effects of the utility model are, compared with prior art described open firing heat-treatment furnace tail gas recycling device by pump by in the heat transferring medium suction heat exchanger components in the heat transferring medium storage bin, by heat exchange, heat the heat transferring medium in the heat exchanger components in heat exchanger components, heating heat transferring medium later is for other heating equipments, cooling heat transferring medium later passes back into the heat transferring medium storage bin, not only simple in structure, be easy to realize; And reasonably having utilized the tail gas heat quantity of direct-fired heater, energy-saving and emission-reduction, reduced production cost to a certain extent.
The accompanying drawing explanation
Fig. 1 is the structural representation of the open firing heat-treatment furnace tail gas recycling device that provides of the utility model specific embodiment 1.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.
Refer to shown in Figure 1, in the present embodiment, a kind of open firing heat-treatment furnace tail gas recycling device comprises the petticoat pipe 2 that is installed on body of heater 1 exhaust end, on described petticoat pipe 2, be fixed with heat exchange coil 3, described heat exchange coil 3 is close to petticoat pipe 2 and is arranged, fluid interchange water in described heat exchange coil, and described heat exchange coil 3 carries out heat exchange by pipeline 4 and heated object 5, on described pipeline 4, is connected with horizontal pump 6 and storage tank 7 for delivery of heat-exchanging water.
During work, by horizontal pump 6 by in the heat-exchanging water suction heat exchange coil 3 in storage tank 7, by with petticoat pipe 2 in high-temperature gas carry out the heat-exchanging water in heat exchange heating heat exchange coil 3, heating heat-exchanging water later is for heating heated object 5, cooling heat-exchanging water later passes back into storage tank 7, and so circulation is heated heated object 5.
Above-mentioned open firing heat-treatment furnace tail gas recycling device has reasonably utilized the tail gas heat quantity of direct-fired heater, and energy-saving and emission-reduction have reduced production cost to a certain extent.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-mentioned example; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
