Abstract

The utility model provides an energy-saving waste heat recovery air heater of a boiler. The air heater is divided into a first airflow partition region and a second airflow partition region, wherein the first airflow partition region and the second airflow partition region are independent and separated from each other. The first airflow partition region is composed of a smoke inlet channel, an upper smoke chamber, a plurality of heat exchange pipes, a lower smoke cavity and a lower smoke discharging pipe. The smoke inlet channel is used for being connected with a smoke discharging channel of the boiler. The second airflow partition region is composed of an air inlet pipe, an upper heat exchange chamber, a hot air induced pipeline, a hot air induced draft fan, a heat exchange pipe chamber and a hot air exhaust pipe opening. The heat exchange pipes of the first airflow partition region are arranged inside the heat exchange pipe chamber of the second airflow partition region.

Description

Boiler energy-saving waste heat recovery fan heater
Technical field
The utility model relates to the energy-saving emission-reducing apparatus field that is applied to Industrial Boiler, and what be specifically related to is a kind of boiler energy-saving waste heat recovery fan heater.
Background technology
Industrial Boiler can produce a large amount of flue gases in production and application, the exhaust gas temperature that boiler is in operation is generally all more than 300 ℃, and this temperature is called as waste heat, and the waste heat great majority are all by chimney, directly to be discharged in atmosphere to go, cause the waste of fuel, affected simultaneously environment.At present also do not have a kind of device to process recycling to these heat energies that slattern.
Summary of the invention
The purpose of this utility model is to provide a kind of boiler energy-saving waste heat recovery fan heater of the heat recovery recycling that boiler exhaust gas can be discharged.
To achieve these goals, the utility model provides following technical scheme:
a kind of boiler energy-saving waste heat recovery fan heater, this fan heater is divided into independently air-flow one subregion and air-flow two subregions, isolation mutually, wherein, air-flow one subregion is by flue, upper smoke chamber, some heat exchanger tubes, lower smoke cavity, the down smoke-discharging pipe forms, flue is for being connected with the smokejack of boiler, air-flow two subregions are by blast pipe, upper thermal exchanging chamber, the hot blast air inducing pipeline, hot-air draught fan, the heat exchanger tube chamber, the hot blast air draft mouth of pipe forms, some heat exchanger tubes of air-flow one subregion are placed in the heat exchanger tube chamber of air-flow two subregions, the principle of this fan heater heat recovery is: the high-temperature flue gas of boiler emission is entered by flue, high-temperature flue gas fully absorbs heat by upper thermal exchanging chamber and heat exchanger tube, blast pipe enter the low temperature pure air by upper thermal exchanging chamber's heat exchange after by hot air inducing pipeline to hot-air draught fan, by the hot-air draught fan drum, advance the heat exchange chamber again, at heat exchange chamber drag effects end, do to stop and by the hot blast air draft mouth of pipe, discharged again.
Further, described blast pipe place is provided with air regulating board.
The beneficial effect that the utility model brings is: the amount of heat recycling that boiler exhaust gas can be given off.
The accompanying drawing explanation
Fig. 1 is the utility model structure and principle schematic.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1, a kind of boiler energy-saving waste heat recovery fan heater, this fan heater are divided into independently air-flow one subregion and air-flow two subregions, mutually isolation.In figure, solid arrow is depicted as air current flow direction in air-flow one subregion, and dotted arrow is depicted as air current flow direction in air-flow two subregions.
wherein, air-flow one subregion is by flue 1, upper smoke chamber 12, some heat exchanger tubes 6, lower smoke cavity 8, down smoke-discharging pipe 9 forms, flue 1 is for being connected with the smokejack of boiler, air-flow two subregions are by blast pipe 3, upper thermal exchanging chamber 2, hot blast air inducing pipeline 11, hot-air draught fan 10, heat exchanger tube chamber 7, the hot blast air draft mouth of pipe 5 forms, some heat exchanger tubes 6 of air-flow one subregion are placed in the heat exchanger tube chamber 7 of air-flow two subregions, the principle of this fan heater heat recovery is: the high-temperature flue gas of boiler emission is entered by flue 1, high-temperature flue gas fully absorbs heat by upper thermal exchanging chamber 2 and heat exchanger tube 6, blast pipe 3 enter Cryogenic air by upper thermal exchanging chamber's 2 heat exchange after by hot air inducing pipeline 11 to hot-air draught fan 10, by hot-air draught fan 10 drums, advance heat exchange chamber 7 again, at heat exchange chamber 7 drag effects ends, do to stop again and discharged by the hot blast air draft mouth of pipe 5, the hot-air of discharging is that pure hot-air can utilize and does oven dry, sterilization etc.The down smoke-discharging pipe 9 cigarette main induced draft fan that runs in, discharge low temperature waste gas.
At the mouth of pipe place of blast pipe 3, designed an air regulating board 4.Can regulate as required the purpose that air regulating board 4 can be realized the temperature of regulation output hot blast.
The above; it is only the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
