Description
Technical Field
The utility model relates to a boiler, specifically speaking are be used for energy-concerving and environment-protective coal fired boiler drum induced air equipment, belong to boiler drum induced air equipment field.
Background
The combustion mode of the domestic industrial pulverized coal boiler is mainly layer combustion, the mode is that coal forms a fuel layer with a certain thickness above a fire grate, and air passes through the coal layer through the fire grate and carries out combustion reaction with fuel. The domestic industrial pulverized coal boiler is suitable for a wide range of coal types, and can effectively burn high-ash low-volatile low-calorific-value stone coal, coal gangue, lignite, inferior anthracite and the like. The method has the outstanding defects of high dust concentration of discharged smoke, high carbon content of fly ash, high power consumption in operation, serious equipment abrasion and the like, and is limited in application. The chinese patent invention entitled "an industrial pulverized coal boiler" with application number "CN 201610425282.9" discloses an industrial pulverized coal boiler, which comprises: a chimney; a boiler body; a coaling conveyor belt for conveying pulverized coal into the boiler body for combustion, one end of the coaling conveyor belt being arranged in the boiler body; one end of the gas pipeline is connected with one side surface of the boiler body; and the dust removal device comprises an induced draft fan, an air blower and dust collectors respectively connected with the two ends of the induced draft fan and the air blower, the air blower is connected with the boiler body, and the induced draft fan is connected with the chimney. However, the equipment needs to be provided with a dust remover for removing dust, so that the equipment investment is increased, and the exhausted flue gas also carries heat to cause waste of heat energy.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model designs a be used for energy-concerving and environment-protective coal fired boiler drum induced air equipment, simple structure, convenient to use, the cost is reduced has practiced thrift the energy.
The technical scheme of the utility model is that:
The utility model provides a furnace that is used for energy-concerving and environment-protective coal fired boiler drum induced air equipment, includes the air-blower, the exit end of air-blower is linked together with coal fired boiler's furnace, coal fired boiler's furnace still is connected with the outlet flue, the outlet flue is linked together with the outlet flue pipe, the outlet flue pipe is the spiral coil that the level set up, spiral coil's bottom through first draught fan with the entry end of air-blower is linked together through the smoke return pipe, and the flue gas is the spiral flow in spiral coil, and the impurity that dust, particulate matter etc. are not burnt can be blanked to spiral coil's bottom gradually, and then introduces coal fired boiler through first draught fan in, the reburning to atmospheric pollution has been.
And the bottom of each spiral coil is communicated with the inlet end of the first induced draft fan.
The spiral coil pipe coils in the periphery of induced air pipeline to flue gas through the spiral coil pipe heats the air in the induced air pipeline, the induced air pipeline through the second draught fan with the entry end of air-blower is linked together, and the air after the heating is introduced in coal fired boiler's furnace by the second draught fan, supports combustion, simultaneously, because the air is heated in advance, has reduced the heat loss in furnace, has practiced thrift the energy, moreover, has reduced the temperature that the interior discharge of spiral coil removed the flue gas for impurity's deposit in the flue gas has improved the purifying effect of flue gas.
The first draught fan and the connecting pipeline of the second draught fan are provided with control valves, so that the gas flow is convenient to control, and the gas regulation of the coal-fired boiler is realized.
The utility model has the advantages that: simple structure, convenient use, reduced cost and energy conservation.
The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is not intended to limit the invention.
Example 1
As shown in fig. 1, a be used for energy-concerving and environment-protective coal fired boiler drum induced air equipment, including the air-blower, the exit end of air-blower 1 is linked together with coal fired boiler 2's furnace 3, coal fired boiler's furnace still is connected with the outlet flue, the outlet flue is linked together with outlet flue pipe 4, outlet flue pipe 4 is the spiral coil that the level set up, spiral coil's bottom through first draught fan 5 with the entry end of air-blower 1 is linked together through return flue pipe 6, and the flue gas is at spiral coil internal spin flow, and the bottom to spiral coil can be blanked gradually to the impurity that does not burn to the greatest extent such as dust, particulate matter, and then in introducing coal fired boiler's furnace through first draught fan, the reburning to atmospheric pollution has been reduced.
And the bottom of each spiral coil is communicated with the inlet end of the first induced draft fan.
The spiral coil pipe coils in the periphery of induced air pipeline 7 to heat the air in the induced air pipeline through the flue gas in the spiral coil pipe, induced air pipeline 7 through second draught fan 8 with the entry end of air-blower 1 is linked together, air after the heating is introduced coal fired boiler's furnace by the second draught fan in, combustion-supporting, simultaneously, because the air is heated in advance, has reduced the heat loss in furnace, has practiced thrift the energy, moreover, has reduced the temperature that the interior discharge of spiral coil removed the flue gas for the precipitation of impurity in the flue gas, has improved the purifying effect of flue gas. The connecting pipeline of the first draught fan 5 and the second draught fan 8 is provided with a control valve 9, so that the gas flow can be controlled conveniently, and the gas regulation of the coal-fired boiler can be realized.
