Description

Environment-friendly hot-water boiler

Affiliated technical field.The utility model relates to a kind of being placed on to be used on the combustion furnace, and available coke or anthracite are made fuel but can be protected the water heater of atmospheric environment.

Background technology.Warming is the living condition of northern resident's indispensability, in the big city, the resident mostly adopts central heating, but in suburbs, little county town, small towns and vast rural area, the place that does not have the central heating condition generally all with coal stove or be equipped with " native heating installation " and warm oneself, is used coal stove to warm oneself and is given off volume of smoke and pernicious gas, pollutant atmosphere is that environmental administration is unallowable.I have designed a kind of main use combustion gas in November, 2000 and have made " energy-saving hot water stove " (seeing patent ZL00253207.7) of fuel and also can use coke or anthracite to make fuel, but when using coke or anthracite to make fuel, flue dust major part in the tail gas falls into heating recirculated water and causes heating installation pipeline dust to stop up, for solving environmental pollution and the heater unit blockage problem that the tail gas dustiness is brought greatly, I am on the basis of " energy-saving hot water stove ", design again and a kind ofly act as a fuel with coke or anthracite, but can avoid flue dust to fall into recirculated water, avoid " environment-friendly hot-water boiler " of contaminated environment.

Summary of the invention.The purpose of this utility model is to provide a kind of: (1) can make the flue dust in most of tail gas not fall into recirculated water, avoids the heating installation pipeline to stop up; (2) most of pernicious gas avoids atmosphere contaminated in the energy eccysis tail gas; (3) can reclaim part of waste heat in the tail gas, improve heat utilization efficiency; (4) can warm oneself and can provide life with the water heater of hot water.

For achieving the above object, the technical scheme that the utility model is taked is: at a column body of heater middle part that coats heat-insulation layer, be provided with water injection pipe, overflow water pipe, the bottom of body of heater is provided with blow-off pipe.The top of stove is provided with bell, there is exhaust outlet at the lid center, establishes exhaust blower on the exhaust outlet, and the sieve plate that is welded with an endless belt sieve aperture below the bell constitutes storage tank on the ring-type with cover plate, this storage tank and heating installation return pipe join, and make whole bell constitute a ring-type spray equipment.The bottom of burner hearth is provided with down the big little cone-shaped hood of, the end opening of cover welds mutually with the body of heater end opening, and the inboard of cone-shaped hood is as passage of flame, and the outside constitutes the lower water tank of water heater with body of heater, the outside of cone-shaped hood is welded with serpentine duct, and furnace body outer wall is stretched out at the conduit two ends.Deploy cyclone dust collectors on the cone-shaped hood, fuse with cone-shaped hood, cone-shaped hood opening from the side suitable for reading has pipeline to communicate with the deduster inlet, and gas enters from the tangential direction of deduster.The first half that the central tube gas outlet of deduster is positioned at burner hearth is higher than body of heater and overflows water pipe, tail gas directly enters among the furnace chamber, for preventing that furnace roof from spraying the water that gets off and falling into deduster, central tube is established bucker on the gas outlet, and the bottom of deduster is provided with cement output tank and stretches out furnace body outer wall.Flue dust flows directly in the refuse bag that the user provides for oneself.

Below in conjunction with accompanying drawing and example the utility model is further specified.

Description of drawings.Please referring to Fig. 1, environment-friendly hot-water boiler comprises the outer column body of heater (4) that heat-insulation layer (8) is arranged, and what be provided with in the body of heater that water injection pipe (7) communicates with radiator overflows water pipe (6), and the bottom is provided with blow-off pipe (19).Furnace roof has slotting lid formula bell (11), exhaust outlet (12) is arranged in the middle of the lid, establish exhaust blower (13) on the exhaust outlet, the sieve plate (14) that is welded with an endless belt sieve aperture below the lid constitutes storage tank (15) on the ring-type with cover plate, this storage tank communicates with an end of return pipe (16), the other end of return pipe joins with heating recirculated water delivery side of pump, when water is sent in the pump circulation, backwater is gone into the ring-type storage tank, and spray among furnace chamber from the sieve aperture outflow continuously, treat that furnace chamber bottom storage tank (18) water is full, just flow into the radiator circulation and so forth from overflowing the mouth of a river.After stove used a period of time, regularly bell and blow-off pipe valve open, flushing burner hearth dirt kept the furnace chamber cleaning that heat transfer is normally carried out.

The Lower Half of burner hearth is provided with a big down little cone-shaped hood (2), the end opening of cover welds mutually with the body of heater end opening, constitute lower water tank (18), the inboard of cover is as passage of flame, the outside of cover is welded with its two-port (1 of serpentine duct (3), 5) stretch out furnace body outer wall, mainly be the device of supply life with hot water, need only from (5) suitable for reading when needing hot water and feed cold water, it is for people to use that lower port (1) promptly flows out warm water, conduit is empty during without hot water, making to increase heat transfer area uses, the burner hearth first half is established the top that cyclone dust collectors (9) are positioned at cone-shaped hood, fuse with cone-shaped hood, cone-shaped hood opening from the side suitable for reading, there is pipeline and cyclone dust collectors inlet to join, gas enters from the tangential direction of deduster, dust is stayed in the device, tail gas enters among the furnace chamber from central tube is suitable for reading, tail gas is drained into outdoor in furnace chamber by exhaust blower after the water washing under the furnace roof spray, the central tube gas outlet is positioned at the burner hearth first half and is higher than body of heater and overflows water pipe (6), and the gas outlet is provided with bucker (10), prevents that furnace roof from spraying the water that gets off and falling into deduster, the deduster bottom has cement output tank (17) to stretch out furnace body outer wall, uses for the dust in the remover.

The specific embodiment.When using this stove water heater is placed on the combustion furnace, hot water entrance pipe be connected with heating system appropriate after, fill with water, start heating with water circulating pump and exhaust blower, continuously spray and continuous overflow are gone in the radiator in stove to make water, ignition combustion stove then, the thermal current that combustion furnace produces is when passage of flame, heat is passed to the water in the passage outside, the thermal current that does not have enough time to pass away enters cyclone dust collectors from the communicating pipe of passage upside with tangential direction, and the effect of deduster has two: one, and the water spray back that sprayed by furnace roof to get off raises water temperature when reducing in the device gas temperature; The 2nd, the flue dust in the air-flow settle down avoid falling into the heating water, tail gas after the dedusting rushes at bucker from central tube, waste heat is passed to the water of spray on bucker, residual gas overflows around bucker, with spray the direct contact heat-exchanging of heating installation backwater that gets off from furnace roof, waste heat in the residual gas is passed to water as much as possible, and the pernicious gas in the eccysis residual gas, residual gas is gone in the atmosphere by the exhaust blower forced-ventilated then.

In recirculated water, add 1% soda ash (Na during having sulfur (S) suggestion heating in coke or the anthracite ₂CO ₃) the heating phase finishes water emptying.
