Abstract
The present invention relates to a multifunctional environment protection boiler which belongs to the field of mechanical manufacture. In view of the problems of high coal consumption, serious pollution, the existence of explosion hidden trouble, etc. existing in the traditional coal boilers, a new-type boiler is designed. The present invention is composed of a boiler body, a feeding port, a coal gas generating chamber and a coal gas combustion chamber and is characterized in that coal is added to the coal gas generating chamber and is conveyed to the coal gas combustion chamber after being gasified, and the converted heat of coal gas after complete combustion is exchanged in a heat exchange chamber. An auxiliary heat exchange chamber is arranged, and waste gas can be discharged through a chimney after dust is removed from the waste gas and the waste gas is desulphurized. The present invention has the characteristics of no smoke, no dust, no pollution, high utilization rate of the coal, no explosion hidden trouble and good trial effect, and is deeply welcomed by users.
Description
Technical field
The present invention relates to mechanical manufacturing field, is a kind of novel environment-friendly boiler specifically.
Background technology
Many defectives such as coal-burning boiler ubiquity coal consumption is big, efficient is low, the billowing contaminated environment of flue dust; Along with progress of science and technology,, but still can't obtain the essence solution though foregoing problems has obtained some progress.
Summary of the invention
A kind of invention of multifunctional environment protection boiler its objective is the problem that exists at above-mentioned traditional coal-burning boiler, has developed a kind of boiler of new structure, and it is that clean-burning way improves coal utilization efficient, reaches the reduction coal consumption after adopting coal to gasify in advance; Sulphur removal before abundant burning by coal gas, the flue gas emptying, dedusting reach the colourless free of contamination purpose of flue gas.
A kind of multifunctional environment protection boiler is to be made of each parts of charging aperture, gas generating chamber, combustion chamber, Heat Room, dirt pocket and chimney, it is characterized in that:
A) gas generating chamber is arranged on the boiler middle part, and the bottom of fire grate is the gas burner, and the rear portion of gas generating chamber and combustion chamber is the main heat exchange chamber, and gas generating chamber and top, main heat exchange chamber are provided with secondary Heat Room;
B) be provided with water sprinkler and an airduct in the gas generating chamber;
C) the indoor secondary air channel that is provided with of gas-fired.
Coal drops into sealed gas generating chamber through charging aperture, coal after the gasification forms fuel gas and enters the combustion chamber, the combustion chamber is under the condition of secondary air channel air feed, after coal gas fully burns in the combustion chamber, enter the main heat exchange chamber, waste heat enters secondary Heat Room and continues the heating heat exchanger tube, and waste gas enters atmosphere through chimney.
Good effect of the present invention is that coal gasifies in gas generator, makes the gas-fired heat supply, has improved coal utilizaton rate effectively, and economizing on coal to reach 70～80%; Heat Room water jacket top is provided with atmospheric communicating pipe, and the assurance boiler is worked under normal pressure, guarantees that boiler operatiopn is safe and reliable; The emptying flue dust makes boiler operatiopn avoid atmosphere pollution after dedusting, desulfurizer are handled.

The specific embodiment
Structure of the present invention and operation mechanism further specify as follows in conjunction with the accompanying drawings:
As seen from Figure 1, the middle part of multifunctional environment protection boiler of the present invention is provided with gas generating chamber 5, and its bottom is a water pipe furnace grate 4, and the fire grate bottom is gas burner 3; The rear portion of gas generating chamber and combustion chamber is main heat exchange chamber 14; Front end in the bottom of combustion chamber and main heat exchange chamber is provided with except that grit chamber 1, and rearward end is provided with dirt pocket 17; Gas generating chamber 5 and 14 tops, main heat exchange chamber are provided with secondary Heat Room 6; Secondary Heat Room top is provided with the air supply line 10, chimney 11 and the rear portion that are communicated with atmosphere and is provided with sulphur removal chamber 12; Be provided with water sprinkler and an airduct 18 in the gas generating chamber 5; Be provided with secondary air channel 20 in the gas burner 3; The heat exchanger tube 15 of main heat exchange chamber 14 is provided with heat-insulation layer; Be provided with water jacket 13 around the body of heater, its water inlet is in the body of heater bottom, and outlet pipe 9 is at the body of heater top, and the body of heater top also is provided with temperature meter base 7 and pressure gauge stand 8.
Operation of the present invention and operation mechanism are as follows: after the ignition of the boiler, drop into closed gas generating chamber 5 gradually by the charging aperture coal that will loose, indoorly be provided with an airduct oxygen supply, also have water jet; The coal that looses forms coal seam, oxide layer, reducing zone, drying layer and destructive distillation layer in gas generating chamber 5; Coal is at high temperature, drying under the sealing condition, destructive distillation, reduction, oxidation, decompose gasification and be fuel gas, enter gas burner 3, and under the condition of secondary air channel oxygen supply, fully burning, produce high temperature, carry out thermal power transfer through main heat exchange chamber 14 by heat exchanger tube 15, can be by pipeline for user's heating, bathing, Saunas uses, and for making full use of heat energy, the heat exchanger tube 15 of main heat exchange chamber 14 is provided with heat-insulation layer, so that minimizing heat loss, the heat that runs off is provided with secondary Heat Room 6 simultaneously for further recycling, through after twice thermal energy exchange, waste gas enters atmosphere by flue through chimney after dirt pocket and the processing of sulphur removal chamber.Because burning is fuel gas, the waste gas of discharge is handled through dedusting, desulfurization, so, by the gas of chimney emptying, though the fuel that boiler is used is coal, emptying be the gas of smokeless and dust free.Fire grate is a water pipe furnace grate, and the cinder of gas generating chamber, is discharged by removing cinder notch 1 after gas burner 3 enters slag removal tank by water pipe furnace grate 4.Environmental pollution has not only been avoided in the coal gasification after-combustion, and simultaneously, the thermal efficiency of coal improves greatly, and through measuring and calculating, coal saving rate is 70～80%.
