A kind of fume recovery heater

Technical field

The utility model is related to a kind of fume recovery heater, belongs to waste heat recovery device technical field.

Background technology

Boiler is a kind of energy conversion, there is chemical energy, electric energy in fuel, boiler output to the energy of boiler input Steam with certain heat energy, high-temperature water or organic heat carrier；The original meaning of pot refers to the water container heated on fire, and stove refers to burning The place of fuel, boiler includes pot and stove two large divisions；The hot water produced in boiler or steam can be directly industrial production and people The people's livelihood is lived and provides required heat energy, also can be converted to mechanical energy by Steam Power Equipment, or passes through generator again by mechanical energy turn It is changed to electric energy；The boiler for providing hot water is referred to as hot-water boiler, is mainly used in life, also there is a small amount of application in industrial production；Produce The boiler of steam is referred to as steam boiler, is often simply called boiler, is used for thermal power station, ship, locomotive and industrial and mining enterprises；The master of boiler The water for wanting operation principle to be that the waste heat in the heat energy or industrial production discharged after a kind of utilization fuel combustion is passed in container, makes Water reach required for temperature or certain pressure steam heat power equipment；But existing boiler is in running, consume energy it is higher, And environmental pollution is serious, the hot gas smog that it is produced directly is discharged from chimney, it is impossible to is obtained secondary utilization, is wasted therein Heat energy.

Utility model content

（One）The technical problem to be solved

To solve the above problems, the utility model proposes a kind of fume recovery heater, after boiler combustion Smog is heated, energy-conserving and environment-protective.

（Two）Technical scheme

Fume recovery heater of the present utility model, including buffer box body；The buffer box body top is respectively arranged with Water inlet and delivery port；The buffer box body side is provided with gas approach；The buffer box body lower section is connected with tube bank；It is described Tube bank lower section is provided with ash disposal cylinder；The ash disposal cylinder side is provided with exhanst gas outlet, and after the internal SP pipes of heating, the gas of cooling leads to Cross exhanst gas outlet discharge；The ash disposal cylinder bottom offers cleaning door；Many SP pipes are installed in the buffer box body and tube bank.

As preferred embodiment, shoot door is installed at the cleaning door, flue gas is contained within dust, dust after cooling Can be dropped accumulation, be discharged from the cleaning door of bottom through shoot door.

Further, the gas approach is connected to boiler, and burning in boiler hot gas smog out is entered by gas approach Enter buffer box body.

Further, the water inlet is connected with cold water inlet.

Further, the delivery port is connected with hot water outlet pipe.

（Three）Beneficial effect

Compared with prior art, fume recovery heater of the present utility model, burning in boiler hot gas smog out is led to Cross gas approach and enter buffer box body, SP pipes are heated, obtain hot water so that the calory burning of boiler can be obtained fully Utilization, and the dust cooled down in flue gas is processed by cleaning door, reduce pollutant emission, reduce environmental pollution, ring Protect energy-conservation.

Description of the drawings

Fig. 1 is overall structure diagram of the present utility model.

Fig. 2 is positive structure diagram of the present utility model.

Fig. 3 is present invention looks up structural representation of the present utility model.

Part in accompanying drawing is labeled as：1- buffer box bodies, 2- water inlets, 3- delivery ports, 4- gas approach, 5- tube banks, 6- Ash disposal cylinder, 7- exhanst gas outlets, 8- cleaning doors, 9-SP pipes, 10- shoot doors.

Specific embodiment

Fume recovery heater as shown in Figure 1 to Figure 3, including buffer box body 1；The top of the buffer box body 1 is respectively It is provided with water inlet 2 and delivery port 3；The side of the buffer box body 1 is provided with gas approach 4；The connection of the lower section of the buffer box body 1 There is tube bank 5；The lower section of tube bank 5 is provided with ash disposal cylinder 6；The side of ash disposal cylinder 6 is provided with exhanst gas outlet 7, the internal SP of heating After pipe 9, the gas of cooling is discharged by exhanst gas outlet 7；The bottom of ash disposal cylinder 6 offers cleaning door 8；The buffer box body 1 Many SP pipes 9 are installed with tube bank 5.

Shoot door 10 is installed, flue gas is contained within dust at the cleaning door 8, dust can drop accumulation after cooling, passes through Shoot door 10 is discharged from the cleaning door 8 of bottom.

The gas approach 4 is connected to boiler（It is not shown）, by boiler（It is not shown）Burn the hot gas smog for coming and pass through cigarette Gas import 4 enters buffer box body 1.

The water inlet 2 is connected with cold water inlet.

The delivery port 3 is connected with hot water outlet pipe.

Fume recovery heater of the present utility model, enters slow by burning in boiler hot gas smog out by gas approach Casing is rushed, the water inlet being connected with cold water inlet, and the water outlet being connected with hot water outlet pipe are provided with the top of buffer box body Mouthful；And by arranging many SP pipes in buffer box body and tube bank, many SP are managed using the hot gas smog from burning in boiler out Heated, obtained hot water；After the internal SP pipes of heating, the gas of cooling is discharged by exhanst gas outlet；Flue gas is contained within dust, cold But dust can drop accumulations after, through shoot door from the cleaning door discharge of bottom.

Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality New spirit and scope are defined.On the premise of without departing from the utility model design concept, this area ordinary person couple Various modifications and improvement that the technical solution of the utility model is made, all should drop into protection domain of the present utility model, this reality With the new technology contents being claimed, all record in detail in the claims.
