Abstract
The invention relates to a heating device, and particularly provides a boiler. The boiler comprises a boiler body and a hearth. The lower portion of the hearth communicates with a ventilation channel. The hearth communicates with an air feeder through a conveying pipeline. A fireproof layer and an insulating layer are sequentially arranged on the outer side of the hearth from interior to exterior. The hearth further communicates with a smoke treatment device. An air inlet pipeline of the smoke treatment device communicates with the hearth. An air outlet pipeline of the smoke treatment device communicates with an air inlet pipe of an induced draft fan. An air outlet pipe of the induced draft fan communicates with the atmosphere. The boiler is reasonable in structure, the insulating layer is arranged on the outer side of the fireproof layer of the hearth, and the combustion condition of fuel close to the fireproof layer is effectively improved. The air feeder feeds air into the hearth, coal is sufficiently combusted accordingly, and coal resources are saved. In addition, a coal gas treatment device is arranged, and pollution to the atmosphere from the waste gas is avoided. The production cost is reduced, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of firing equipment, be specifically related to a kind of boiler.
Background technology
Boiler is as a kind of energy conversion, in boiler, energy is inputted by the chemical energy in coal, electric energy, the form such as heat energy of high-temperature flue gas, and change through boiler, outwards output has the steam of certain heat energy, high-temperature water or organic heat carrier, and wherein the boiler for coal combustion is the most universal.
Boiler includes burner hearth and hot water locker room; burning coal in burner hearth, the produced heat of burning sends the hot water reservoir above burner hearth to, but insufficient situation of burning often occurs in the coal in existing burner hearth; cause the waste of coal resource and heat, add cost.
It addition, the EGT that coal combustion produces is higher, possibly together with substantial amounts of heat, heat is directly discharged from chimney, thus causes the loss of heat.Containing substantial amounts of flue dust in flue gas, it is directly discharged in air, environment is caused pollution.
Summary of the invention
It is an object of the invention to overcome the defect of prior art, it is provided that a kind of boiler that can reduce the wasting of resources and environmental pollution can be reduced.
To this end, the invention provides a kind of boiler, including body of heater and burner hearth, described burner hearth is connected with pressure fan by conveyance conduit；The outside of described burner hearth is sequentially provided with flame retardant coating and heat-insulation layer from inside to outside.Also being communicated with flue gas processing device on burner hearth, the admission line of described flue gas processing device connects with burner hearth, and outlet pipe connects with the air inlet pipe of air exhauster, the escape pipe of air exhauster and atmosphere.
As the improvement in structure, the escape pipe of described air exhauster being communicated with arm, described arm connects with burner hearth.
As the improvement in structure, described flue gas processing device is hermetic container, is provided with spray equipment in flue gas processing device, and described spray equipment is 3 grades of spray equipments and setting of mutually staggering.
As the improvement in structure, in described flue gas processing device, it is provided with at least two-layer column plate, the hole that for flue gas or water pass through on described column plate, is distributed.
As the improvement in structure, also including the fire grate being fixed on burner hearth bottom, described fire grate is made up of multiple fire grate segments being independently arranged side by side, and each fire grate segment is provided with multiple air vent.Each fire grate segment is provided with multiple air vent, is beneficial to ventilate, and high temperature resistance is effective, owing to fire grate segment is independently arranged, if a fire grate segment damages, it is only necessary to changing the fire grate segment broken down, convenient maintenance uses, and reduces cost.
As preferably, the shower nozzle that described spray equipment is used is spiral nozzle.Using spiral nozzle, in the case of can avoiding having a power failure or shutting down, the situation of dust blocking, does not interferes with dust removing effects.
Beneficial effects of the present invention: this boiler that the present invention provides, rational in infrastructure, it is provided with heat-insulation layer in the outside of burner hearth flame retardant coating, effectively improve the burning condition of fuel at the flame retardant coating, and be air-supply in burner hearth by pressure fan so that coal fully burns, and has saved coal resource；It addition, be provided with coal gas processing device, it is to avoid air is polluted by waste gas.Reduce production cost, improve production efficiency.

Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, it is further elucidated with the present invention.
Embodiment:
A kind of boiler as shown in Figure 1, including body of heater 1 and burner hearth 12, described burner hearth 12 is connected with pressure fan 14 by conveyance conduit 13；Pressure fan 14 carries air in burner hearth 12 so that coal is fully contacted with oxygen, and coal fully burns in burner hearth 12.The outside of described burner hearth 12 is sequentially provided with flame retardant coating 3 and heat-insulation layer 2 from inside to outside.Coal burns in burner hearth 12, and the water of body of heater 1 absorbs heat by flame retardant coating 3, and owing to flame retardant coating 3 is outside equipped with heat-insulation layer 2, heat-insulation layer 2 can reduce scattering and disappearing of heat, not only reduces the waste of the energy, and enables to coal and be prone to fully burn.Also being communicated with flue gas processing device 5 on burner hearth 12, the admission line 4 of described flue gas processing device 5 connects with burner hearth 12, and outlet pipe 8 connects with the air inlet pipe of air exhauster 9, the escape pipe 10 of air exhauster 9 and atmosphere.Described flue gas processing device 5 is hermetic container, is provided with spray equipment 6 in flue gas processing device 5, and described spray equipment 6 is 3 grades of spray equipments and setting of mutually staggering.The shower nozzle that spray equipment is used is spiral nozzle.Using spiral nozzle, in the case of can avoiding having a power failure or shutting down, the situation of dust blocking, does not interferes with dust removing effects.Being communicated with arm 11 on the escape pipe 10 of described air exhauster 9, described arm 11 connects with burner hearth 12.
The useless flue gas that coal combustion in burner hearth 12 produces enters in flue gas processing device 5, at least two-layer column plate 7 it is provided with in described flue gas processing device 5, the hole that for flue gas or water pass through is distributed on described column plate 7, the contact area of flue gas and shower water can be increased, flue dust is fully absorbed by spray equipment 6, flue gas with moisture is extracted out by air exhauster 9, a part is discharged into outside air, another part enters in burner hearth 12, flue gas with water forms water gas in burner hearth 12, promotes the abundant burning of coal further.
