Description

Hydrogen dioxy liquid gasification environment-friendly energy-saving hot-blast stove

Technical field

The utility model relates to a kind of normal-pressure boiler, relates in particular to hydrogen dioxy liquid gasification environment-friendly energy-saving hot-blast stove.

Background technology

Existing boiler has normal-pressure boiler, forms such as steam boiler, and normal-pressure boiler comprises high-temperature gasification formula, versions such as combustion-type, heat energy return-stroke type, fully automatic fuel-oil, combustion gas, combustion electricity formula repeatedly, and these boiler environment-friendly functions fall behind, and the thermal efficiency is low.For example, just there are five big shortcomings in the present hot-blast stove that uses: (1) can not hydrogen dioxy liquid gasification, and combustion, wastes huge.(2) do not have the design of dust-removal and desulfurizing, the environmental protection rate is low.(3) its design be up and down repeatedly, forced circulation heats mode, so the blower power that needs is very big.Power consumption is considerable.(4) its designed solid cast fire bars hundreds of jin that weighs, and often burnt out, not only waste but also heavy, (5) its function singleness, specially stove special use can not supply boiling water simultaneously when sending hot blast, cause the waste of considerable heat energy.

The utility model content

For overcoming above-mentioned shortcoming, the purpose of this utility model is to provide a kind of hydrogen dioxy liquid gasification environment-friendly energy-saving hot-blast stove.

For achieving the above object, the technical solution of the utility model realizes as follows: hydrogen dioxy liquid gasification environment-friendly energy-saving hot-blast stove, comprise body of heater, be provided with the water containing chamber body in the body of heater, the body of heater bottom is provided with gasification combustion chamber, the bottom, combustion chamber is provided with groove shape drawing and pulling type fire bars, the fire bars center is provided with tank, tank is communicated with tap by pipeline, be provided with annular fire resistant heat preserving circle around the fire bars of bottom, combustion chamber, insulation ring top is provided with annular cellular Gasifying corer, and top, combustion chamber is provided with the high temperature resistant cement distributor, and Gasifying corer top is provided with spiral ascending manner warm-air pipe, the warm-air pipe end is provided with hot-blast outlet, body of heater is provided with air blast outward, and air blast is connected spiral warm-air pipe and gasification combustion chamber by three-way pipe with by-pass cock, and the body of heater top is provided with outlet flue, outlet flue top is provided with down pot form drag device and dirt pocket, be provided with in the dirt pocket and purify waste water, the dirt pocket top is provided with the buck shower nozzle, and the buck shower nozzle is connected with alkaline-water box.

The utility model can be used for cold zone, the icing elimination of underground mineral exploitation well head, supplies boiling water simultaneously, has solved because of freezing well head is dwindled the continuous difficult problem of elevator accident.And the large space of units such as megastore, workshop, supermarket, school, hospital, hotel heating wind problem.The utility model compared with prior art has five big advantages: first point: the gasification of hydrogen dioxy liquid makes bituminous coal smokeless combustion, environmental protection and energy saving.Second point: be provided with the dust-removal and desulfurizing facility, the course of work of its smoke dispersal, dust removal and desulphurization is as follows, the high-temperature flue gas in the burner hearth by outlet flue, go out and run into located in the above falling on the pot form drag device, earlier the bulky grain flue dust is returned in the entry, its waste heat is absorbed by resistance gauge.Turn to outlet flue after the residue flue gas is obstructed, at this moment be located at the buck shower nozzle on outlet flue top, buck is met head on spray down, and be sprinkled upon the top of resistance gauge, because of resistance gauge has high temperature, produce alkaline steam at once, the acidic flue gas of residue sulfur-bearing is comprehensively clean, discharge out of the furnace by the chimney of increasing again.What be seen is the white vapor that smokeless and dust free does not have sulphur.Thirdly: the helix tube of this stove design is to heat mode along rotating rising naturally, so the blower power that needs is little, wind-force is big, and heat is imitated height, saving coal electric energy.The 4th point: the cast iron stove strip of this stove design is a groove shapes, the commutative use in two, its center is provided with intake chamber, one end is bar shaped, be used for the burning of blocks such as lump coal, timber, cow dung, horsehit, the other end is the honeycomb aperture, inserts tiny fuel such as flammable fine flour coal, sawdust, wheat bran in the stove.Fire bars is connected by the tap on communicating pipe and the outside body of heater, make water enter high temperature groove shape fire bars inside, produce steam at once, rush at the combustion chamber ejection on top, rapidly steam is resolved into hydrogen and oxygen by the high temperature in the burner hearth, mix the coal gas of high temperature in the burner hearth again, produce active combustion at once, similarly be to add fuel to the flames, the boundary that reaches a high degree of excellence.Be provided with cover plate above the fire bars, cover plate is provided with cellular aperture, discharge for steam, and because of the protection of water is arranged in the fire bars, thus be not easy to be burnt out, therefore durable in use.The 5th point: this stove is in the periphery of spiral warm-air pipe, be provided with the water containing chamber body, utilized the residue heat energy that washes away the spiral warm-air pipe, the water in the cavity is boiled, therefore when sending hot blast, can supply boiling water, do not need the stove that boils water in addition, thereby province's coal, power saving economizes stoker personnel wage, one stove is dual-purpose, saves considerable.Therefore the utlity model has environmental protection and energy saving, characteristics multiple functional, easy to use.
