Abstract
The utility model relates to an atmospheric pressure vertical coal gas cyclone boiler with double boiler hearth, and belongs to the fluid heater field of the heat-generation device. The utility model is provided with two boiler hearths. The top of the coal gas generation boiler hearth is provided with an evacuation valve. The top of the combustion boiler hearth is provided with a smoke outlet throat opening. A boiler hearth connecting pipe is arranged between the two boiler hearths. The utility model has the advantages of simple structure, convenient operation and thorough combustion. The utility model overcomes the defect caused by the existing periodic combustion condition, conforms to the environmental protection requirements, is suitable for a plurality of coal types and breaking power coal, reduces the combustion cost, and improves the combustion efficiency.
Description
The utility model atmospheric vertical double-hearth gas cyclone furnace belongs to generally the fluid heater of heat-generating device field, and it is the normal-pressure boiler of a kind of heating, heat supply water.
Existing vertical boiler is when adding coal combustion, owing to be subjected to the restriction of other factors, be easy to generate that burning is insufficient, boiler exhaust gas exceeds standard, and adopts general twin furnace to add coal combustion, can not solve the periodicity that smoke evacuation has when adding coal combustion, vertical boiler requires high to the burning of coal classification.
The purpose of this utility model is to solve weak point of the prior art, provides a kind of and avoids adding coal combustion time smoke evacuation to exceed standard, and is suitable for the atmospheric vertical double-hearth gas cyclone furnace of multiple coal and broken smalls.
The purpose of this utility model reaches by following measure, it is by boiler jacket, flue, burner hearth, exceedingly high pipe, advance compositions such as return pipe, it is by two burner hearths, wherein 1 is the gas generator thorax, in gas generator thorax top layout dispersal valve is arranged, 1 is burner hearth in addition, in the burner hearth top layout smoke aditus laryngis is arranged, two shared smoke aditus laryngis of burner hearth, a shared flue, there is burner hearth to take between gas generator thorax and the burner hearth, during work, the high-temperature gas of the semi-coal gas state that the gas generator thorax is produced enters burner hearth by the burner hearth adapter and secondary wind exports the imaginary circle that the air that is sprayed forms abundant disturbance, prolongs the carbon granule and the time of staying of dust granule in burner hearth, under the effect of centrifugal force and gravity, be forced to stay in the burner hearth, reduction is to the dust emissions amount of atmosphere, and when a burner hearth coal, another burner hearth can provide higher ignition temperature; And making fully disturbance in the burner hearth, burning is completely.
For increasing air agitation in the burner hearth; Be provided with 1 °-18 ° of certain included angle between the burner hearth adapter between gas generator thorax and the burner hearth and the line of two burner hearth center lines.
For further reducing the dust emissions amount, the center line of the smoke aditus laryngis of burner hearth top layout departs from the burner hearth center, makes dust granule be forced to stay in the burner hearth.
The utility model is simple in structure, easy and simple to handle, burning thoroughly, overcome the drawback that the situation of present periodicity burning is brought, compliance with environmental protection requirements, applicable multiple coal and broken smalls reduce the burning cost, improve efficiency of combustion.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is A-A cutaway views of accompanying drawing 1.
Accompanying drawing 3 is rearviews of accompanying drawing 1.
Below in conjunction with accompanying drawing the utility model is further described:
As accompanying drawing 1, shown in the accompanying drawing 2, the utility model is by exceedingly high pipe (1), atmospheric communicating pipe (2), manhole (3), shell (4), flue (5), dispersal valve (6), manhole (7), smoke aditus laryngis (8), secondary blast pipe (9), fire door (10), a wind control valve (11), ash door (12), burner hearth is taken over (13), gas generator thorax (14), burner hearth (15) is formed, it is by two burner hearths, 1 is that gas generator thorax (14) has dispersal valve (6) in gas generator thorax (14) top layout, one is burner hearth (15), in burner hearth (15) top layout smoke aditus laryngis (8) is arranged, center line bias combustion burner hearth (15) center of smoke aditus laryngis (8), two shared smoke aditus laryngis of burner hearth (8), a shared smoke flue (5), there is burner hearth to take over (13) between gas generator thorax (14) and the burner hearth (15), be arranged to certain included angle between the line of burner hearth adapter (13) and two burner hearth center lines, angle: scope is 1 ° of-18 ° of scope, and is best about 8 °.
As shown in Figure 3, be provided with outlet pipe (16), water inlet pipe (17), explosion-proof adapter (18), an ajutage (19), blow-off pipe (20) in the boiler side.
Claims (3)
1, a kind of atmospheric vertical double-hearth gas cyclone furnace, it is made up of exceedingly high pipe, shell, fire door, flue, water inlet pipe and water outlet pipe, blow-off pipe etc., it is characterized in that: it is by two burner hearths, one is the gas generator thorax, in gas generator thorax top layout dispersal valve is arranged, one is burner hearth, in the burner hearth top layout smoke aditus laryngis is arranged, and has burner hearth to take between gas generator thorax and the burner hearth.
2, atmospheric vertical double-hearth gas cyclone furnace according to claim 1, it is characterized in that burner hearth between gas generator thorax and the burner hearth is taken over and the line of two burner hearth center lines between be provided with 1 °-18 ° of certain included angle.
