The utility model at first with normal temperature air from blast pipe, reversal valve enters the heat-accumulator tank of a side, air is from flow through from bottom to top heat storage in the heat-accumulator tank of heat-accumulator tank, air is heated to 850 ℃-1200 ℃, when entering body of heater, be sprayed onto corresponding heat-exchanging chamber in the body of heater with the fuel mix burning of Bunker lower end discharge and through the bright eruption mouth, the flue gas that burning produces can only enter the heat-exchanging chamber of opposite side by the perforate on vertical clapboard top, again through the interior heat storage that is provided with of the heat-accumulator tank of opposite side, flue gas passes through heat storage from top to bottom in heat-accumulator tank, with the heat transferred heat storage of flue gas and be accumulated in the heat storage, and by once more in stove reverse flow to the heat storage of opposite side, promptly between two heat storages, carry out heat release back and forth, be cooled to below 100 ℃ up to flue gas, after reaching the low-temperature values of setting, cigarette is by the emptying of circulation line process reversal valve in the stove, after the reversal valve commutation, the reversal valve of another strand cold air after commutation enters another heat-accumulator tank by another circulation line and carry out exothermic process once more between two heat storage.Be 20s-200s (adjustable by concrete condition) commutating period of reversal valve, the reversal valve that operating temperature is not high switches with certain frequency, make the heat-accumulator tank of body of heater both sides be in the alternation state of accumulation of heat and heat release accumulation of heat and heat release, thereby reach energy-conservation and reduction NO
xThe purpose of discharge capacity, its basic purpose are to allow fuel fully burning under high-temperature low-oxygen concentration, and temperature efficiency is up to 95%, and heat recovery rate reaches more than 80%.Therefore, the utility model pollutes little, the efficiency of combustion height, and consume fuel is few.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a sectional structure schematic diagram of the present utility model.
The specific embodiment
A kind of solid fuel heat accumulating type high-temperature air burning gasification furnace, comprise the bright eruption mouth 6 and the ashes bucket that are equipped with in body of heater 1, ashes bucket bottom is being provided with cleaning door, body of heater 1 inner chamber middle part is separated into the left and right heat-exchanging chamber 3,4 of symmetry by vertical dividing plate 10, the top of left and right heat-exchanging chamber 3,4 is interconnected by through hole 2, and the bottom of left and right heat-exchanging chamber 3,4 is being provided with left and right ashes bucket 9,12 respectively; The left side of symmetry is being set on the outer furnace wall of body of heater 1, right Bunker 5,11 and left, right heat-accumulator tank 7,18, a left side, right heat-accumulator tank 7, heat storage 8 is being set respectively in 18, a left side, right heat-exchanging chamber 3,4 perforate and left sides by being provided with on the furnace wall respectively, right Bunker 5,11 lower ending opening, a left side, right heat-accumulator tank 7,18 upper end open interconnect, a left side, right heat-accumulator tank 7,18 lower ending openings respectively with a left side, right circulation line 17,13 connect, a left side, right circulation line 17,13 the other end separately is connected with two commutation air outlets of reversal valve 15 respectively, air inlet by reversal valve 15 is communicated with blast pipe 14, and the other end of blast pipe 14 is connected with the air outlet of frequency conversion fan.
