Abstract
The utility model relates to an air heater, composed of a medium heat pipe boiler with a burning chamber, a ventilator and an air duct. The condensing section of the medium heat pipe boiler is designed into a finned pipe heat exchanger which is installed in the air duct, the medium inlet end of the upper part of the heat exchanger is communicated with the upper part of the evaporating section of the heat pipe boiler, the medium outlet end of the lower part of the heat exchanger is communicated with the bottom of the evaporating section of the heat pipe boiler, an exhaust valve is arranged on a return pipe, and the boiler and the base of a fan are arranged on the upper part of a wheel drawing device. The utility model has simple structure, small size, high heat efficiency, low manufacturing cost and low running and maintaining cost.
Description
The utility model relates to a kind of hot air apparatus, particularly a kind of mandatory medium heat tubular type hot air apparatus.
Hot blast is widely used in national economy and the people's lives.Provide its structure of equipment of hot blast varied at present, but all do not break away from the form of flue gas and the heat exchange of air partition, flue gas and air partition heat exchange structure, not only the coefficient of heat transfer is little, and metal consumption is big, and scaling loss very easily after being heated, equipment life is short, the air-heater electrisity consumption is big, the equipment investment height, and difficulty maximizes.And provide the warm-air drier of thermal source with common steam boiler or hot-water boiler, and the former condensate water loss is bigger, and the power consumption of latter's water circulating pump is higher.Above-mentioned various structures are fixed, and are not removable.
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of coefficient of heat transfer big, and metal consumption is little, and is safe and reliable, and operation and maintenance cost is low, moves packaged type hot air apparatus easily.
The purpose of this utility model is to realize like this.Mainly by the medium heat pipe boiler of band combustion chamber and be placed on ventilation blower on the base and air duct interconnects and forms.Its main points are to be connected with on the ventilation blower air duct, the section of condensing of medium heat pipe boiler is a finned tube exchanger, it is installed in the air duct, the upper collecting chamber medium inlet end of finned tube exchanger is communicated with by steam guiding tube with heat pipe boiler evaporator section top, its next part case media outlet is communicated with by liquid back pipe with heat pipe boiler evaporator section bottom, on this liquid back pipe exhaust-valve is housed.
The utility model is simple in structure, volume is little, equipment manufacturing cost and operation and maintenance cost are low, the heat transfer efficiency height, no burning problems, stable, safe and reliable, also can arbitrarily move operating location, be not only applicable to heating, more be applicable to thawing of oven dry such as cereal, vegetables, food, timber, material and cold district winter construction ground, the heating of construction material, mine ventilation etc., compare metal consumption with air dividing wall type hot-blast stove with traditional flue gas and reduce more than 30%, increase by 500 above service life.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of finned tube exchanger.
The accompanying drawings preferred embodiment of the utility model.As shown in Figure 1, 2, the utility model mainly is made up of with air duct 2 the medium heat pipe boiler 1 of band combustion chamber, the ventilation blower 14 that is placed on the base 23.Air duct is connected in turn by path uiform section section 17, divergent segment 16, big footpath uiform section section 24, converging transition 18 and hot-blast outlet 19, and the path section is linked to each other with ventilation blower, and adjusting valve 15 is housed herein, and thermometer 20 is equipped with at hot-blast outlet section place.Core of the present utility model is that the section of condensing with medium heat pipe boiler 1 is designed to high-efficiency fin heat exchange of heat pipe 4, and is installed in the big footpath uiform section section of air duct.Finned tube exchanger 4 is made up of finned tube element 7, upper collecting chamber 8, next part case 9 and housing 10, upper collecting chamber 8 is communicated with by steam guiding tube 11 with the top of medium heat pipe boiler 1 evaporator section 5, next part case 9 is communicated with by liquid back pipe 12 with medium heat pipe boiler evaporator section bottom, and deaeration valve 13 is housed on the liquid back pipe.The utility model can be placed on tugboat device 3 tops with medium heat pipe boiler and ventilation blower base, and the tugboat device is made up of chassis 21 and castor 22, and this structure can arbitrarily be moved operating location.
The utility model is when needing hot wind supply, at first start medium heat pipe boiler 1, open exhaust-valve 13 simultaneously, adopt the hot type method that the air in the medium heat pipe boiler is discharged, meet the demands to vacuum, close exhaust-valve immediately, this moment, the medium heat pipe boiler entered normal operating conditions, the medium that heat pipe boiler uses, the liquid that the liquid that can be made up of water and anticolodal according to purposes or water, anticolodal and organic antifreeze are formed.Medium 6 heat absorption boilings, the steam that produces in evaporator section 5 is sent into rapidly in the finned tube exchanger 4 along steam guiding tube 11, its wall temperature is raise, at this moment start ventilation blower 14, Cryogenic air is heated after skimming over high-efficiency fin heat exchange of heat pipe 4 at a high speed, and the steam in the finned tube exchanger is condensed into liquid medium after heat exchange, and sends the bottom of medium heat pipe boiler 1 evaporator section 5 back to along liquid back pipe 12, again be heated evaporation again, so go round and begin again.Heated air is given the hot blast user along hot air duct.
