In the work process, the fuel can be sent onto the first row of heat exchange tubes 14 from a fuel filling opening 9, and then, the fuel can combust. The fume can be exhausted from a fume outlet 7 finally. The cold air can enter in the stove from an air inlet 13. After the cold air flows through an air passage 12 and the four rows of heat exchange tubes, the cold air can be exhausted from an air outlet 18.

Description

A kind of novel hot-blast stove

The utility model belongs to the boiler in the thermo-mechanical machine class.

The hot-blast stove that uses in the current industrial, generally be to be fuel with coal, fuel oil, can not be with the offal such as the wood shavings of bavin leather, straw and industrial processes factory in the agricultural, saw is smeared etc. and to be used as fuel, make some to discard in vain, cause the waste of the energy as the material of fuel utilization.

It is the hot-blast stove of fuel that the purpose of this utility model provides a kind of straw with plant, faggot, wood chip etc., makes full use of the heat energy of combustible, and its architectural feature is to have adopted the backfire burning and the multilayer pipe heat exchange structure of more roomy burner hearth.

Be described with reference to the accompanying drawings structure of the present utility model.Fig. 1 is a structural representation of the present utility model, and tube 1 is the supporting part of full stove in the body of heater.The main composition portion of stove all links together with it, and it is a cylindrical element.Body of heater urceolus 2 is to be enclosed within the body of heater an outer cylindrical element of tube, the lower end by under encircle the end 19 with its with body of heater in tube welded together, in it and the body of heater tin between toroidal cavity be air channel 12.Body of heater inner core 3 is to be contained in the cylindrical element in the tube in the body of heater, and it links to each other with tube in the body of heater by first, second, third and fourth row's heat exchanger tube.Baffle plate 4 is the rings that 1/4th breach are arranged, and is welded in the body of heater on the tube, is used for controlling the glide path of air.External spiral plate 5 is to be welded in the spiral plate that being used on the tube outer surface in the body of heater guides air glide path.Inside spin plate 6 is to be welded in the body of heater on the tube inner surface, the spiral plate of guiding flue gas flow direction.Exhanst gas outlet 7 is pipes that penetrate air channel 12, and it is drawn the flue gas in the gas flue outside the stove, top cover 8 be in body of heater inner core, the body of heater tube and the body of heater urceolus between connector.Fuel fill mouth 9 is fuel used input ports, is a flaring cone part.Furnace chamber 10 is fuel combustion spaces in body of heater.Gas flue 11 be in the body of heater tube and the body of heater inner core between annular chamber, when high-temperature flue gas flows through heat passed to tube and inside spin plate thereof in the body of heater in this chamber, air channel 12 is cavitys between tube and the body of heater urceolus in the body of heater, when cold air flows through in this chamber from body of heater tube and external spiral plate absorption heat and be heated.Air intake 13 is imports of the cold air sent here by air blast.First row's heat exchanger tube 14, second row's heat exchanger tube 15, the 3rd row's heat exchanger tube 16 and the 4th row's heat exchanger tube 18 are the part of main heat exchange element of the present utility model.Every row's heat exchanger is made up of a plurality of pipes, and its quantity can be 4,5, also can be 6 that the axis phase angle difference between each row is 90 °, they pass gas flue 11 and opening in air channel 12.Air outlet slit 17 is that the air after being heated is drawn thus.Encircle the end 19 down and be the end that is connected of tube and body of heater urceolus lower end in the body of heater.Ash port 20 is to fall into bottom of furnace body thus after burning bavin ash later etc. sees through gap of each row's heat exchanger tube, is removed by cleaning door 21 again.

Fig. 2 is replenishing of Fig. 1, and it has shown the ring with 1/4th big or small breach that is shaped as of baffle plate 4.

Fig. 3 is new second structural representation of this practicality, also be the additional figure of Fig. 1, it be among Fig. 1 baffle plate 4 lower surfaces with the vertical view of lower part, its median septum 1, dividing plate 2 25 and dividing plate 3 27 are three rectangular steel plates, they stand upright on, and the lower end is welded in down ring at the end 19 in the air channel 12, by a face down bonding of tube 1 in the body of heater in body of heater on the tube 1, the upper end is welded on the baffle plate 4, its angle branch position is dividing plate 1 and dividing plate 2 25, just in time aim at two ends of 1/4th breach of baffle plate 4, dividing plate 3 27 and dividing plate 1 are on same diameter, and such three dividing plates are divided into i.e. first district 22, three districts to the air channel 12 of baffle plate below 4 in this situation, second district 24 and the 3rd district 26.In the course of the work, air enters first and arranges heat exchanger tube 14 and the 3rd row's heat exchanger tube 16 from second district 24, and inflow first district 22 enters second row's heat exchanger tube 15 again and the 4th row's heat exchanger tube 18 flows in the 3rd district 26, after air outlet slit 17 discharges.
