Abstract
The utility model discloses a kind of energy-saving coal fired boiler, including boiler body and filter mantle, the blast pipe of boiler is connected with air-introduced machine, the smoke exhaust pipe of boiler and the threaded one end of filter mantle connect, the other end of filter mantle is threaded with the smoke inlet of air blower, and gas flowmeter is installed in smoke inlet, the outlet flue of air blower is connected by exhaust gases passes with the blast pipe, the exhaust gases passes are also connected with oxygen generator by oxygen cathete, the junction of oxygen cathete and exhaust gases passes is provided with magnetic valve, also include a controller, the input of controller is connected with gas flowmeter, output end is connected with magnetic valve and oxygen generator.The utility model can be substantially reduced forced draft induced draft amount, and flue gas ceaselessly reuses, and take full advantage of the heat of flue gas, while the flue gas for discharging chimney will be seldom, can mitigate the burden of the dedusting of desulfurization, few, the energy-conserving and environment-protective that denitration becomes.
Description
Technical field
It the utility model is related to energy-conserving and environment-protective field, and in particular to a kind of energy-saving coal fired boiler.
Background technology
Coal-burning boiler is to be transmitted to interstitial water using heat caused by the oxygen in air and coal generation chemical reaction, passes through water
Heat and energy are transmitted to user, the processing of flue gas in the prior art easily causes pollution mostly using the form directly discharged
While, these heats are wasted significantly.
Utility model content
To solve the above problems, the utility model provides a kind of energy-saving coal fired boiler, the heat of flue gas is taken full advantage of,
Energy-conserving and environment-protective.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of energy-saving coal fired boiler, including boiler body and filter mantle, the blast pipe of boiler are connected with air-introduced machine, boiler
The threaded one end of smoke exhaust pipe and filter mantle connects, and the other end of filter mantle is threaded with the smoke inlet of air blower, and smoke inlet
Gas flowmeter is inside installed, the outlet flue of air blower is connected by exhaust gases passes with the blast pipe, the exhaust gases passes
Oxygen generator is also connected with by oxygen cathete, the junction of oxygen cathete and exhaust gases passes is provided with magnetic valve, in addition to a controller,
The input of controller is connected with gas flowmeter, and output end is connected with magnetic valve and oxygen generator.
Preferably, the filter mantle 5 includes a cylinder cover body and the screen pack being fixedly mounted in cover body.
Preferably, the controller is single-chip microcomputer.
The utility model has the advantages that：
Forced draft induced draft amount can be substantially reduced, flue gas ceaselessly reuses, and takes full advantage of the heat of flue gas, simultaneously
The flue gas for discharging chimney will be seldom, can mitigate the burden of the dedusting of desulfurization, few, the energy-conserving and environment-protective that denitration becomes.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of filter mantle in the utility model embodiment.
Embodiment
In order that the purpose of this utility model and advantage are more clearly understood, the utility model is entered with reference to embodiments
Row is further described.It should be appreciated that specific embodiment described herein is only to explain the utility model, and do not have to
In restriction the utility model.
As Figure 1-Figure 2, the utility model embodiment is provided including boiler body 1 and filter mantle 5, the air intake of boiler
Pipe 2 is connected with air-introduced machine 3, and the smoke exhaust pipe 4 of boiler is connected with the threaded one end of filter mantle 5, the other end threaded connection of filter mantle 5
There is the smoke inlet of air blower 7, the setting of filter mantle can avoid substantial amounts of flue dust from leading into gas flowmeter, air blower, flue gas
Can very easily it be changed using the connected mode of screw thread so as to result in blockage in road；And gas stream is installed in smoke inlet
Gauge 6, the monitoring of exhaust smoke level on the one hand can be realized, so as to control oxygenerator to carry out the supply of demand oxygen, on the other hand
It can also find that filter mantle whether there is blockage problem in time, so as to realize the timely replacing of filter mantle；The outlet flue of air blower 7
It is connected by exhaust gases passes 9 with the blast pipe 2, the exhaust gases passes 9 are also connected with oxygen generator 10 by oxygen cathete, oxygen therapy
The junction of pipe and exhaust gases passes 9 is provided with magnetic valve 8, in addition to a controller, input and the gas flowmeter 6 of controller
It is connected, output end is connected with magnetic valve 8 and oxygen generator 10.
The filter mantle 5 includes a cylinder cover body 51 and the screen pack 52 being fixedly mounted in cover body.
The controller is single-chip microcomputer.
The air blower 7 includes air blower body and the smoke-intake pipe and pipe positioned at air blower body both ends, described
Pipe is connected with the threaded one end of exhaust gases passes 9, and check valve is also equipped with the oxygen cathete, can only allow oxygen from system
Oxygen machine enters exhaust gases passes 9；The exhaust gases passes 9 are wrapped with heat-insulation layer, reduce heat damage of the flue gas in course of conveying
Lose.
This specific implementation carries out the supply of oxygen, and the flue gas mixing of boiler by oxygenerator, as long as reaching coal-burning boiler
Oxygen dosage just can meet requirement, forced draft induced draft amount can be so substantially reduced, flue gas ceaselessly reuses, and heat is not lost
Lose, the flue gas for discharging chimney will be seldom, can mitigate the burden of the dedusting of desulfurization, few, the forced draft induced draft that denitration becomes
Significantly save.Heat loss due to exhaust gas also greatly reduces.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
