The utility model discloses a be connected with heat transfer device at the exhaust port with the retort, the flue gas that produces in the biological charcoal production process carries out the heat exchange with cold water in heat transfer device, and the flue gas of flue gas cooling after, discharges through purifying the back, and the cold water heat absorption intensifies and becomes hot water, and hot water can supply people's heating bathing to use to reach the purpose of the waste heat in the recycle flue gas, energy saving and emission reduction.
Description
technical field:
The mechanical equipment technical field that the utility model charcoal is manufactured, is specifically related to a kind of charring furnace with function of recovering waste heat.
background technology:
Charcoal, be bio-organic materials (biomass) in anoxic or anoxybiotic environment, the solid product generated after Low Temperature Thermal cracking.Charcoal both can be used as the high-quality energy, soil improvement agent, also can be used as reductive agent, fertilizer slow release carrier and carbon dioxide sequestration agent etc., be widely used in carbon fixation and emission reduction, water source purifying, heavy metal adsorption and soil improvement etc., can to a certain extent for the hot issue that the whole world such as climate change, environmental pollution and soil function degeneration are deeply concerned provides solution.
Charcoal in process of production, have a large amount of flue gases to produce, at present these flue gases or be directly discharged in air, be discharged in air again after purifying treatment, but the temperature of the flue gas produced in charcoal production process is more than 200 DEG C, even have more than 500 DEG C, containing a large amount of heats in these flue gases, be discharged in air at this point, cause a large amount of heat wastes.
utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of charring furnace with function of recovering waste heat, and it is being connected with heat-exchanger rig by the smoke outlet of charring furnace, and the flue gas produced in charcoal production process carries out heat exchange with cold water in heat-exchanger rig, flue gas cool-down cools, after flue gas through purification after discharge, cold water heat absorption intensification become hot water, hot water can for people's heating and bathing, thus reach the object of the waste heat recycled in flue gas, energy-saving and emission-reduction.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of charring furnace with function of recovering waste heat, wherein: comprise charring furnace, the smoke outlet of described charring furnace is communicated with the inlet mouth of heat transfer tube, described heat transfer tube comprises interior pipe and outer tube, and interior pipe installs within the outer tube, is exhaust gases passes in interior pipe, interior pipe one end is inlet mouth, the other end is air outlet, and be pipelined channel between interior pipe and outer tube, outer tube two ends arrange water-in and water outlet respectively.
Further, described inner tube outer surface is fixed with radiating fin, and radiating fin is arranged in the pipelined channel between interior pipe and outer tube.
Further, described outer tube outer surface is enclosed with thermal insulation layer.
Further, described radiating fin is helical fin, and in pipelined channel, the flow direction of current is identical with the rotation direction of radiating fin.
The beneficial effects of the utility model are:
1, the utility model is being connected with heat-exchanger rig by the smoke outlet of charring furnace, the flue gas produced in charcoal production process carries out heat exchange with cold water in heat-exchanger rig, flue gas cool-down cools, after flue gas through purification after discharge, cold water heat absorption intensification becomes hot water, hot water for people's heating and bathing, thus can reach the object of the waste heat recycled in flue gas, energy-saving and emission-reduction.
2, the outside surface of interior pipe of the present utility model arranges spiral heat dissipation fin, and the radiating efficiency of inner tube smoke in increasing, increases the contact area of current and interior pipe, improves the thermal absorption efficiency of current.
3, the utility model structure is simple, easy to use, cheap, and the heat in the flue gas that can effectively produce in organism-absorbing charcoal production process, waste heat recovery recycling, reaches the object of energy-saving and emission-reduction.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of heat transfer tube of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of charring furnace with function of recovering waste heat, comprises charring furnace 1, and the smoke outlet 2 of described charring furnace 1 is communicated with the inlet mouth 8 of heat transfer tube 3, and described heat transfer tube 3 comprises interior pipe 4 and outer tube 6, and outer tube 6 outside surface is enclosed with thermal insulation layer 13.Interior pipe 4 is installed in outer tube 6, and be exhaust gases passes 5 in interior pipe 4, interior pipe 4 one end is inlet mouth 8, and the other end is air outlet 9, and be pipelined channel 7 between interior pipe 4 and outer tube 6, outer tube 6 two ends arrange water-in 10 and water outlet 11 respectively.Interior pipe 4 outside surface is fixed with radiating fin 12, and radiating fin 12 is arranged in the pipelined channel 7 between interior pipe 4 and outer tube 6.Radiating fin 12 is helical fin, and in pipelined channel 7, the flow direction of current is identical with the rotation direction of radiating fin 12.
During use, charring furnace 1 is produced the flue gas produced in charcoal process and is discharged from smoke outlet 2, then the inlet mouth 8 through heat transfer tube 3 enters interior pipe 4, flow along interior pipe 4 to air outlet 9, cold water enters the pipelined channel 7 between interior pipe 4 and outer tube 6 from the water-in 10 that outer tube 6 is arranged, spiral working direction along spiral heat dissipation fin 12 flows, in flow process, absorb the heat that flue gas distributes, water temperature raises, the water outlet 11 of outer tube 6, by pipeline communication bathroom or heating radiator, for people's bathing or heating, thus reaches the object of waste heat recovery recycling.
