Abstract
The utility model discloses a hot-air supply device taking steam as heat source, comprising an insulation case equipped with a cold air inlet and a hot air outlet. A plurality of steam heaters are arranged in the insulation case, wherein the upper ends of the steam heaters are connected with an upper collector which is connected with a main steam duct, and the lower ends of the steam heaters are connected with a lower collector which is connected with a drain pipe and a return pipe. A hot water preheater is arranged in the insulation case at the side of the cold air inlet, an upper end of the hot water preheater is connected with the return pipe, and a lower end of the hot water preheater is connected with an upper hose of boiler. The benefit of taking steam as heat source is that steam supply quantity, temperature and pressure are stable, thereby stabilizing temperature of hot air, and ensuring water uniformity of dried grain. High-temperature return water of steam heaters are led to the hot water preheater to preheat cold air, thereby realizing reutilization of high-temperature return water, thoroughly utilizing hot energy, and discharging return water with temperature reaching to 60 DEG C.
Description
Technical field
The utility model relates to a kind of air heating apparatus, especially a kind of air heating apparatus that hot blast is provided for foodstuff drying device.
Background technology
Along with the development of northern alcohol, starch, oils industry, these industries all need a large amount of corns or soybean as processing raw material every year in recent years.Because the corn of new results or soybean moisture height are unsuitable for directly processing and store,, it is reached be convenient to the moisture processing and store so must handle through oven dry.These industries mostly extensively adopt the drying plant of tower dryer as corn and soybean at present, but these dryers mainly all are to provide thermal source by independent supporting coal-fired hot-blast stove, these hot-blast stoves exist hot blast temperature wayward, can be when hot blast temperature is too high with the grain charing, even initiation fire, simultaneously, also make these users face problems such as investment is big, occupied ground is big, increase pollution sources.
The utility model content
The technical problem that utility model will solve, the technical problems to be solved in the utility model provide a kind of with steam be thermal source provide the device of hot blast for foodstuff drying device.
The technical scheme that the technical solution problem is taked: a kind of is the hot wind supply device of thermal source with steam, include the insulation casing of inlet of cold air and hot air outlet, a plurality of steam heaters are arranged in the casing, the upper end of steam heater links to each other with the upper set device, the upper set device connects main steam line, the lower end of steam heater links to each other with following collector, following collector connects blow-off pipe and return duct, inlet of cold air side in casing is provided with the hot water preheater, described hot water preheater upper end links to each other with return duct, and the lower end links to each other with boiler feed water pipe.
As improvement of the present utility model, on return duct, be provided with water separator.
Described water separator is made of bypass pipe and the steam trap in parallel with bypass pipe.
As further improvement of the utility model, the upper set device is provided with thermometer and Pressure gauge.
On the pipeline of hot water preheater lower end, also be provided with the hot water pipeline pump as of the present utility model further the improvement again.
As preferred implementation of the present utility model, described steam heater and hot water preheater are finned heat exchanger tube.
Beneficial effect: owing to be thermal source with steam, benefit is that evaporation capacity for engine, temperature and pressure are more stable, makes the hot blast temperature substantially constant like this, make grain heat-drying after the moisture uniformity be guaranteed; Owing to adopted high-temperature tempering importing hot water preheater that cold air is carried out preheating with steam heater, realized that high-temperature tempering utilizes again, make full use of heat energy, discharge return water temperature at last and can reach 60 ℃; Owing to be provided with the hot water pipeline pump and make the return water system forced circulation, avoid the winter pipeline to freeze; Owing to adopt finned heat exchanger tube, make the utility model heat exchange efficiency height, floor space little, in addition, adopt the utility model to provide hot blast for foodstuff drying device, do not need to join in addition hot-blast stove, reduced investment, eliminated pollution sources, energy-conserving and environment-protective, simple to operate.
