Description
Technical field
The present invention relates to the water tank type heat exchanger, especially a kind of high energy-saving residual-heat exchanger.
Background technology
Chinese patent CN86204390U discloses a kind of " back yard industry stove residue heat water heater ", it is to increase some parallel to each other or cross pipes on existing jacket type waste-heated water-tank, be connected on that the cylindrical cavity surface is on one section smoke discharging pipe of chimney within the water tank, the connecting leg that its cross section is ellipticity and has a fin constitutes.The cold water that enters casing through tank shell and connecting leg heat exchange rapidly intensification face become can be for producing or the hot water output of life usefulness.But this water heater also has the following disadvantages: (one) high-pressure cold water directly injects from bottom half, is easy to generate eddy current and causes hot and cold water to be mixed, and reduces leaving water temperature; (2) some water delivery connecting legs that are parallel to each other or intersect of oblique layout and fin have increased the resistance that flue gas is flowed in the flue, occur clogging phenomenon easily; (3) traditional cylindrical flue heat exchange area is less.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of improved, its structure is more reasonable, heat exchange efficiency is higher, can save the high energy-saving residual-heat exchanger of a large amount of fuel; The present invention also aims to make this residual-heat exchanger safer, guarantee effluent characteristics, be easy to observe, be convenient to the blowdown deashing.
The technical solution adopted in the present invention is: high energy-saving residual-heat exchanger, contain staving, water inlet pipe, outlet pipe, blast pipe, air bleeding valve, the boiler flange, flue flange, its design feature is that the lower end of described staving is provided with lower cover, the upper end is provided with loam cake, be connected enclosure under the reverse frustoconic between lower cover and the boiler flange, be connected enclosure on the truncated cone-shaped between loam cake and the flue flange, on, affixed some spiral flues between the lower cover, the top of lower cover is provided with the cold water dispenser of the aperture that gathers, spiral flue passes cold water dispenser and seals affixedly with it, and the bucket between lower cover and the cold water dispenser is connected to water inlet pipe on the wall.
On the water inlet pipe of the present invention check valve is housed.Be connected to blow-off pipe and blowoff valve on the bucket wall between described lower cover and the cold water dispenser, thermometer also is equipped with on the top of bucket wall.On the upper end of described upward enclosure and the circle ring column between the flue flange thermal insulation valve is housed.Described go up have in the enclosure several inspection sockets and thereon the configuration inspection mouth renovate, renovate to be equipped with and renovate snap close.
The invention has the beneficial effects as follows: (1) is owing to be provided with the cold water dispenser 5 of iris type above lower cover 3, then formed a cold water cavity in the bottom of staving 10, its restriction high-pressure cold water can only be movable in cold water cavity, avoid producing eddy current, prevent that hot and cold water from mixing, reducing leaving water temperature, water sees through aperture also can reduce hydraulic pressure, make cold water be evenly distributed on the bottom of staving, distinguish the hot and cold water level; (2) flue 11 of many spiral trends can increase the frictional force of hot gas and flue, increase to attach property, makes the heat of flue gas pass to walling of flue more fully and carries out heat exchange, and the cold water in the staving is heated rapidly; (3) the following enclosure 6 of reverse frustoconic is equivalent to a distributor, the pyrotechnics that it will discharge in the boiler is distributed in each spiral flue 11 that is contained on the lower cover 3, because the diameter of lower cover 3 equals the diameter of bore in the enclosure 6 down, so size is bigger, a plurality of spiral flues 11 can be set on it, general each flue intracavity section amasss the sectional area of sum greater than former flue, thereby flue gas resistance is descended; And the last enclosure 7 of truncated cone-shaped is equivalent to a smoke-collecting apparatus, and it will put together from next flue gas in the spiral flue 11 again, discharge from chimney by flue flange 9; (4) effect of thermal insulation valve 17 is the combustion chamber door can be closed after boiler pressure reaches operating pressure, thermal insulation valve 17 is closed to be incubated simultaneously, heat is stored in the staving, thereby reaches fuel-saving purpose; Check valve 2 can prevent the high-pressure pump aqueous reflux in the staving of back that quits work, and avoids anhydrous empty the burning; Air bleeding valve 14 is closed when operation, air bleeding valve should be opened when out of service; Blowoff valve 16 can regularly be discharged dirt impurity in the staving.

Fig. 2 is the A-A cutaway view after Fig. 1 removes water pipe.
Fig. 3 is the B-B cutaway view after Fig. 1 removes water pipe.
The specific embodiment
As shown in the figure, present embodiment comprises water inlet pipe 1, check valve 2, lower cover 3, loam cake 4, cold water dispenser 5, enclosure 6 down, goes up enclosure 7, boiler flange 8, flue flange 9, staving 10, spiral flue 11, outlet pipe 12, blast pipe 13, air bleeding valve 14, blow-off pipe 15, blowoff valve 16, thermal insulation valve 17, inspection socket renovate 18, renovate snap close 19, thermometer 20.
Operation principle of the present invention is: the scorching hot boiler pyrotechnics of introducing from boiler flange 8 disperses the back to enter smoke-collecting apparatus from spiral flue 11 by distributor, discharges through chimney behind the fume centralized again; High-pressure hydraulic pump injects cold water cavity to cold water from water inlet 1, and the aperture thick by cold water dispenser also up permeates the water under high pressure decompression uniformly, and hot water is extruded delivery port 12, supplies with and uses.Cold water in 11 pairs of stavings of screw type flue heats, and inspection socket is renovated 18 with inspection socket at ordinary times and covered inspection socket for checking that deashing uses, and adds and renovate snap close 19 and lock, with anti-gas-leak.
