Description
Technical field
The present invention relates to a kind of coal-burning boiler, particularly relate to a kind of atmospheric gasification hot-water boiler.
Background technology
The hot-water boiler of prior art, its operation principle is lower furnace body combustor combust fuel heat release, heat energy is absorbed by upper furnace body heat sink, though the thermal efficiency can be effectively improved through technological improvement, but cannot fundamentally release coal fire discharged thing pollution on the environment, although some product utilization Coal Gasification Technology, but operation is complicated and vaporizer is in pressure-bearing duty, there is certain potential safety hazard, and effect is on the low side.
Summary of the invention
Present invention aim to address the deficiencies in the prior art, it is provided that a kind of thermal efficiency energy-conservation normal-pressure hot-water boiler higher, more environmentally friendly.
The present invention includes front furnace body and rear furnace body, for horizontal forebody-afterbody structure, its body of heater includes front furnace body 1, rear furnace body 24, hooks slag door 4 and exhaust opening 21, wherein front furnace body 1 is provided with combustion gasification room, rear furnace body is provided with purification absorption chamber, water inlet 20 is arranged on rear furnace body outer wall, and outlet 14 is arranged on rear furnace body upper end；Combustion gasification room in described front furnace body 1 is divided into the left and right combustor 27,26 on top and the left and right vaporizer 29,28 of bottom by the partition 25 being arranged in the middle of heat-utilizing stove comb 7, coal filling hole 2,3 it is respectively equipped with above left and right combustor 27,26, and communicate by being arranged on the burner 9 of crossing bottom partition, the purification absorption chamber in described rear furnace body 24 is divided into secondary combustion chamber 15, upper smoke-box 16, ash removing opening 17 and 18 4 smoke dust ducts of lower smoke-box by upper and lower two partitions 23；In described combustion gasification chamber interior walls upper end with rear furnace body 24, purify absorption chamber junction set vent 10 and 11, complete the connection of fire road, described front furnace body and the outside disjunctor water pipe 6 by top of rear furnace body connect as one, the internal rear furnace body multitube reciprocation cycle water pipe 19 that passes through communicates with heat-utilizing stove comb 7, completes water route connection.
Described heat-utilizing stove comb is best in water cycle performance when being 30 degree of angles with horizontal line downwards.
Above described disjunctor water pipe, drain tap 12 can be set, the stifled impact that water circulation is caused of gas can be avoided.
Can arrange lower fire grating 22, shoot door 5, sewage draining exit 8 below described combustion gasification room, lower fire grating effect is to realize lime-ash to separate.
Water temperature probe 13, the convenient size observing water temperature can be set above described outlet.
It is to burn the carbon-coating that descending pyrotechnics introduces another combustor up with hot react counter that the present invention crosses the effect of burner 9, and crossing vent 10 and 11 be control left and right combustor and the controllable turnover door of the mutual phase transformation of left and right vaporizer effect.Owing to using said structure, after combustion process is coal combustion heat release, burn waste gas CO2And little granule carbon granules enters vaporizer, occurring reduction reaction to generate CO gas, reaction product enters secondary combustion chamber, and burning particles precipitates further at upper and lower smoke-box, combustion heat release, ultimately produce for pure CO2Waste gas, thus emission colorless and odorless, pure transparent, efficiently solve the smoke contamination that fire coal causes, and by reversible chemical reaction, the combustion heat release value of fuel is improve 20%.Water circulation is the high humidity district entering combustion gasification outdoor floor after cold water first enters the heat absorption of multitube reciprocation cycle, exhalant region is entered finally by disjunctor water pipe, discharged by outlet, heat can be absorbed to greatest extent, waste gas exhaust temperature is less than 100 DEG C, has the more energy-conserving and environment-protective of more similar energy-conserving product.
Accompanying drawing explanation
Fig. 1 is body of heater top view, Fig. 2 be front furnace body along I-I sectional view, Fig. 3 is front furnace body rear wall sectional view along II-II body of heater, and Fig. 4 is that body of heater is along III-III side sectional view.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is elaborated:
As shown in Fig. 1,2,3 and 4, its body of heater includes front furnace body 1, rear furnace body 24, hooks slag door 4 and exhaust opening 21, and wherein front furnace body 1 is provided with combustion gasification room, and rear furnace body 24 is provided with purification absorption chamber, water inlet 20 is arranged on rear furnace body outer wall, and outlet 14 is arranged on rear furnace body upper end；Combustion gasification room in described front furnace body 1 is divided into the left and right combustor 27,26 on top and the left and right vaporizer 29,28 of bottom by the partition 25 being arranged in the middle of heat-utilizing stove comb 7, coal filling hole 2,3 it is respectively equipped with above combustion gasification room, and communicate by being arranged on the burner 9 of crossing bottom partition, the purification absorption chamber in described rear furnace body 24 is divided into secondary combustion chamber 15, upper smoke-box 16, ash removing opening 17 and 18 4 smoke dust ducts of lower smoke-box by upper and lower two partitions 23；In described combustion gasification chamber interior walls upper end with rear furnace body, purify absorption chamber junction set vent 10 and 11, complete the connection of fire road, described front furnace body and the outside disjunctor water pipe 6 by top of rear furnace body connect as one, the internal rear furnace body multitube reciprocation cycle water pipe 19 that passes through communicates with heat-utilizing stove comb 7, and heat-utilizing stove comb 7 is preferably in being downwards 30 ° of angles with horizontal line, completes water route and connects.Drain tap 12 can be set above disjunctor water pipe 6, lower fire grating 22, shoot door 5, sewage draining exit 8 can be set below combustion gasification room, water temperature probe 13 can be set above outlet 14.
When the present invention adds fuel, by coal filling hole 2,3 simultaneously toward combustor coal and light, through the combustion-supporting burning of air inducing, simultaneously close off stove gate 2, hook slag door 4, shoot door 5 and cross vent 11, now fire is burnt descending through heat-utilizing stove comb 7, vaporizer 28 by the right combustor of coal filling hole 3 26, then enters left vaporizer 29 at burner 9 by crossing, and pyrotechnics is up through the right hot carbon-coating of combustor 27, dust is filtered, CO2It is reduced into CO by hot carbon-coating, passed through vent 10 enter secondary combustion chamber 15 and come downwards to lower smoke-box 18 along multitube reciprocation cycle water pipe 19, then upper smoke-box 16 of turning back back comes again downwards to lower smoke-box 18, discharge finally by exhaust opening 21, secondary combustion chamber, on the flue dust that precipitates further of smoke-box and lower smoke-box cleared up by ash removing opening 17.
When right combustor 26 coal burns to incandescent state, then simultaneously close off stove gate 3, hook slag door 4, shoot door 5, cross vent 10, open stove gate 2 and cross vent 11, now fire is instead burnt by left combustor 27 under pass through heat-utilizing stove comb 7, left vaporizer 29, cross burner 9 enter right vaporizer 28, pyrotechnics up through right combustor 26 hot carbon-coating generation reduction reaction and through vent 11 enter rear furnace body purify absorption chamber complete purify and heat absorption circulate；Water circulation then enters the high-temperature region of combustion gasification outdoor layer by water inlet 20 after multitube reciprocation cycle is absorbed heat, and is discharged by outlet 14 finally by disjunctor water pipe 6.
