Background technology

Existing vapourizing furnace is as main take fire coal, the coal combustion release of heat, the vapourizing furnace body rolls the water jacket that is welded by steel plate, water in the water jacket absorbs the heat of coal combustion release and produces water vapor, water molecules in the water vapor is sent into furnace bottom by pipeline again, with the main component carbon of coal, add by a certain percentage in addition air, generate coal gas with airborne major ingredient oxygen reaction.Because water leg structure must adopt doughnut-shaped steel plate, cost is high, and bearing capacity is low, so existing vapourizing furnace is all worked under low-pressure state, steam quality is low, and the output gas quality is low.

Summary of the invention

The shortcoming that exists for solving existing vapourizing furnace, thereby the utility model is saved cost with the pipe frame structure that water jacket makes annular header and pipe into, improve bearing capacity, improve combustion gas quality, the integral gasifier of the fuel such as other biomass that not only can coal combustion can also burn.

The purpose of this utility model is realized by following technical scheme: a kind of integral gasifier, it comprises vapourizing furnace 26 and pot 24 two portions, wherein vapourizing furnace 26 is by gasifier water-cooling wall pipe 14, connect on the vapourizing furnace, lower

annular header

10,19, the pipe frame structure of looping header and pipe, vapourizing furnace water outlet base 11 is set on the annular header 10 on the vapourizing furnace, vapourizing furnace water inlet pipe 18 is set on the annular header 19 under the vapourizing furnace, vapourizing furnace blowdown base 27, coal filling hole 28 is set on the body of heater, total blast pipe 17 connects respectively solar or lunar halo 13, upcast ventilation pipe 12, lower solar or lunar halo 16, blast inlet 22 under lower air conduit 15 and the stove, the burner hearth 29 interior rotating grates 20 that arrange, rotating grate 20 is welded on the ash-pan 21; The pot 24 that arranges on the vapourizing furnace 26 is by pot water wall tube 5 and pot convection bank 6, connect up and down drum 30, the lower annular header 8 of pot, on the lower annular header 8 of pot pot water inlet pipe 9, pot blow-off pipe 7 are set, pot water lever mark rest 3, pot blowdown base 4, steam outlet pipe 2, pot safety valve base 1, pot tensimeter base 23 are set on the drum 30.

The utility model is rational in infrastructure, the vapourizing furnace body rolled to be welded by steel plate make gasifier water-cooling wall pipe 14 into, connect the upper and lower annular header 10 of vapourizing furnace, 19, the pipe frame structure of looping header and pipe, saved widely manufacturing firm and user's cost, improve bearing capacity and steam quality, the inflammable gas quality that produces improves, not only can coal combustion can also the burn integral gasifier of the fuel such as other biomass, it is simple to operate, cost, easy to maintenance, thermo-efficiency is high.

Description of drawings

Fig. 1 is the utility model cross-sectional schematic;

Fig. 2 is that the external structure synoptic diagram is looked on the utility model left side.

Embodiment

The below utilizes drawings and Examples that the utility model is further described.

With reference to Fig. 1-2, a kind of integral gasifier, it comprises vapourizing furnace 26 and pot 24 two portions, wherein vapourizing furnace 26 is by gasifier water-cooling wall pipe 14, connect on the vapourizing furnace, lower

annular header

10,19, the pipe frame structure of looping header and pipe, vapourizing furnace water outlet base 11 is set on the annular header 10 on the vapourizing furnace, vapourizing furnace water inlet pipe 18 is set on the annular header 19 under the vapourizing furnace, vapourizing furnace blowdown base 27, coal filling hole 28 is set on the body of heater, and total blast pipe 17 connects respectively solar or lunar halo 13, upcast ventilation pipe 12, lower solar or lunar halo 16, blast inlet 22 under lower air conduit 15 and the stove, the burner hearth 29 interior rotating grates 20 that arrange, rotating grate 20 is welded on the ash-pan 21; The pot 24 that arranges on the vapourizing furnace 26 is by pot water wall tube 5 and pot convection bank 6, connect up and down drum 30, the lower annular header 8 of pot, on the lower annular header 8 of pot pot water inlet pipe 9, pot blow-off pipe 7 are set, pot water lever mark rest 3, pot blowdown base 4, steam outlet pipe 2, pot safety valve base 1, pot tensimeter base 23 are set on the drum 30.

Its principle of work is: water enters annular header 19 under the vapourizing furnace by vapourizing furnace water inlet pipe 18, water is heated along gasifier water-cooling wall pipe 14 absorption burner hearths 29 heats and rises to annular header 10 on the vapourizing furnace, hot water continues to draw along vapourizing furnace water outlet base 11, introduced in the lower annular header 8 of pot by pot water inlet pipe 9, if want the high steam of pressure, water should be drawn from vapourizing furnace water outlet base 11 rear by after the hot water pump pressurization, enter again a pot lower annular header 8, hot water continues to rise after pot water wall tube 5 and pot convection bank 6 heat absorptions, part water becomes steam and enters drum 30, in continuous endothermic process, water becomes steam and reaches rated pressure from steam outlet pipe 2 discharges.A part is delivered to the hot system that uses, and sub-fraction input rotating grate 20 times is used for vapourizing furnace 26 gas making.Pot water lever mark rest 3 is set on the drum 30, thereby can observes the moisturizing of water level control water pump, pot blowdown base 4 is for dirt, the body refuse got rid of in the drum 30, and pot safety valve base 1, pot tensimeter base 23 are used for controlling, observe pot 24 interior vapor pressures.
