Description
Technical field
The utility model belongs to bulk curing barn energy-conserving and emission-cutting technology field, is specifically related to a kind of bulk curing barn waste heat of chimney of tobacco flue-curing bulk curing barn waste heat of chimney that utilizes and utilizes heat exchanger.
Background technology
Tobacco flue-curing is on the one hand the Biochemical changes process of the conversion of organic substance, decomposition and some condensation, reflects the change procedure of tobacco leaf intrinsic chemical composition, the physical process being moisture content in leaves evaporation on the other hand and scattering and disappearing.And this chemistry and physical change process, need outside certain leaf texture's temperature and environment temperature, also need the envionmental humidity reduced gradually.The place that current China mainly adopts and promote bulk curing barn to modulate as tobacco flue-curing, by coal combustion heat change to the state of tobacco leaf environmental condition is provided.
Tobacco leaf toasts in the process of modulation in bulk curing barn, and the consumption of heat can be divided into effective heat dissipation and invalid heat dissipation two broad aspect.Get rid of the heat that in tobacco leaf, moisture consumes and the atmosphere temperature rising heat dissipation for hydrofuge when effective heat dissipation refers to baking tobacco leaves, generally account for 20% ~ 35%.Invalid heat dissipation comprises hydrofuge heat loss, heat loss due to exhaust gas, building enclosure radiation loss, non-complete combustion of fuel loses, radiation heat loss becomes estranged other heat loss etc.
The research such as Gong Changrong shows, the thermal loss that chimney emission is taken away is called heat loss due to exhaust gas, and main relevant with exhaust gas temperature and exhaust smoke level, China's bulk curing barn chimney emission temperature is generally at 150 DEG C.This heat loss is generally 15% ~ 25%, and as improper in made a fire, air excess is more, can reach more than 25%.
Utility model content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of bulk curing barn waste heat of chimney to utilize heat exchanger
, it cangather the waste heat of chimney emission, can be used for heating barn hydrofuge air, increase the dehumidification by condensation temperature difference to be separated to realize hydro-thermal, also can be used for preheating the air entered from barn cold-air flap, improve the coal-fired heat collecting efficiency of hothouse hearth, to reduce heat loss due to exhaust gas, reach the object reducing coal consumption, energy-saving and emission-reduction.
The utility model solves the technical scheme that its technical problem adopts: a kind of bulk curing barn waste heat of chimney utilizes heat exchanger, comprise one and be installed at heat exchanger shell square between the burner hearth radiating tube of existing bulk curing barn and chimney, be provided with in this housing some establish adopt heat pipe, be respectively equipped with in the top and bottom that these adopt heat pipe and adopt hot pipe assembly for what be communicated with that each adopts heat pipe, respectively be provided with one respectively for what adopt that hot pipe assembly externally stretches out at the upper and lower surface of this housing and adopt heat pipe installing hole, wherein be positioned at the extension adopting hot pipe assembly of upper end for adopting heat pipe air outlet, be positioned at the extension adopting hot pipe assembly of lower end for adopting heat pipe air inlet, adopt heat pipe air inlet and connect barn moistureproof window, adopt heat pipe air outlet and connect barn dehumidifier.
The left and right sides is on the housing respectively equipped with air inlet and the air outlet of outwardly convex, and wherein air inlet connects with burner hearth radiating tube, and air outlet then connects with chimney.
The beneficial effects of the utility model are: before the flue gas of bulk curing barn burner hearth combustion coal generation directly discharges chimney, by UTILIZATION OF VESIDUAL HEAT IN heat exchanger, flue gas is carried out to the double absorption of heat energy, and again recycle, improve the collecting efficiency of coal-fired heat, decrease the heat-energy losses of smoke evacuation, can coal consumption be saved in bake process, have and improve the coal-fired heat collecting efficiency of hothouse hearth, reduce heat loss due to exhaust gas, reduce the feature of coal consumption, energy-saving and emission-reduction.
