Abstract
The utility model discloses an octagonal type swirling and air inlet grate with multiple layers. The structural shape of the grate body is an octagonal conical hood-shaped structure, and the side face of the cone is provided with a vent. The upper side of the vent is covered by an access board, the outer end of which is provided with an outer side plate. The octagonal type swirling and air inlet grate with multiple layers has the advantages of distributing wind in the furnace body evenly, improving the gas velocity and strength greatly, impelling the full contact reaction between a gasification agent and coal particles (increasing the content of CO and H2 in coal gas and reducing the content of CO2) and increasing the gas caloric value. The content of CO2 and ash residue is reduced obviously, that is, CO2 is less than 5 percent and carbon content in the ash residue is less than 15 percent.
Description
Technical field
The utility model relates to a kind of multilayer octet formula eddy flow air intake grate, especially relates to a kind of grate that is applicable to atmospheric fixed bed gas-producer.
Background technology
The present atmospheric fixed bed gas-producer of producing of China all is the two stage type gas generating furnace of being introduced by the U.S., Britain, Italy by the A II 13 type single hop stoves and the eighties of USSR (Union of Soviet Socialist Republics) introduction with reference to nineteen fifties basically.With regard to the non-pressurized fixed bed coal gas producer overall technology level of selling on the current market, not very advanced.Particularly Chang Yong grate structure formation mostly is 5～6 layers of disc type through type air vent channel, and wind distributing face is long-pending less than normal, the air strength in straight-through air channel is on the low side, and it is insufficient to cause vaporized chemical to contact with the coal grain, and it is insufficient to gasify, the coal grain that has not gasified is discharged with slag, causes waste.Used grate material mostly is cast iron, bursts easily during high temperature.This situation is badly in need of changing.
Summary of the invention
The utility model technical issues that need to address provide a kind of multilayer octet formula eddy flow air intake grate, change the structure and the material of existing grate, make its cloth wind even, and it is more abundant to gasify, the purpose that reaches not only energy-conservation work-ing life but also prolong.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of multilayer octet formula eddy flow air intake grate, the grate body structure is shaped as the hood-shaped structure of anistree cone, cone side arrangement ventilation hole, the ventilation hole top covers attachment strap, and the attachment strap outer end is provided with outer panel.
The further improvement of the utility model concrete structure is: each side arrangement 3～6 row's ventilation hole of grate body.
The further improvement of the utility model concrete structure is: grate intracoelomic cavity ventilation hole place is provided with diversion trench.
The further improvement of the utility model concrete structure is: described grate intracoelomic cavity is provided with gusset.
Because the technical progress of having adopted technique scheme, the utility model to obtain is:
Use the utility model can make body of heater cloth wind even, and gas velocity and intensity improves greatly, impel between vaporized chemical and the coal grain fully contact reacts (improve CO and H2 content in the coal gas, reduce CO2 content), thus the raising caloric power of gas.CO2 and cinder content obviously reduce, i.e. CO2＜5%. ash content carbons＜15%.
Grate intracoelomic cavity ventilation hole place is provided with diversion trench, can make air-flow form the eddy flow state.
Described grate intracoelomic cavity is provided with gusset, can strengthen grate body intensity, prevents the grate body deformability.
The grate body, attachment strap, outer panel material are heat-resisting manganese steel plate, because of its good heat resistance, can effectively avoid being out of shape or bursting.
Description of drawings

Fig. 2 is the A enlarged view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1;
Among the figure: 1, top board, 2, the grate body, 3, diversion trench, 4, attachment strap, 5, outer panel, 6, ventilation hole, 7, gusset.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further details:
As shown in Figure 1, grate body 2 structural shapes of the present utility model are the hood-shaped structure of anistree cone, and the top of anistree cone is provided with top board 1, cone side arrangement ventilation hole 6, and the ventilation hole top covers attachment strap 4, and the attachment strap outer end is provided with outer panel 5; Attachment strap and outer panel can prevent coal-fired gambling plug intake opening.
As shown in Figure 1, 2, grate intracoelomic cavity ventilation hole place is provided with diversion trench 3.The grate intracoelomic cavity is provided with gusset 7.
As shown in Figure 3, grate body 2 each side arrangement 3-6 row ventilation hole 6.
In the production, fire coal covers the grate external surface, is ventilated by the grate intracoelomic cavity.
Claims (5)
