Description

Garbage furnace structure with cyclone separator

Technical Field

The utility model relates to a waste heat boiler technical field specifically is a take cyclone's rubbish stove structure.

Background

At present, a conventional arrangement mode of a waste heat boiler is that an evaporator, a high-temperature superheater, a medium-temperature superheater and a low-temperature superheater are sequentially arranged on a horizontal flue, and an economizer is arranged at the tail part of the waste heat boiler. The boiler outlet flue is connected with a tail flue gas purification device (a denitration device, a dust removal device and the like) in the rear, and in the actual use process, the flue gas dust amount is large, a large-area dust removal device needs to be arranged at the tail flue, and a large amount of space is occupied.

Disclosure of Invention

In order to solve the problem that dust collector area is big in current exhaust-heat boiler afterbody flue department, the utility model provides a take cyclone's rubbish stove structure, its dust purification pressure that can alleviate the afterbody flue reduces dust collector area occupied.

The technical scheme is as follows: the garbage furnace structure with the cyclone separator comprises a horizontal flue and a tail flue and is characterized in that the cyclone separator is arranged between the horizontal flue and the tail flue, a smoke inlet of the cyclone separator is connected with the horizontal flue, a smoke outlet of the cyclone separator is connected with the tail flue, an ash conveying device is arranged at the bottom of a dust outlet of the cyclone separator, and expansion joints are arranged at the joint of the cyclone separator and the horizontal flue and at the joint of the cyclone separator and the tail flue.

The cyclone separator is further characterized in that castable is laid on the inner wall of the cyclone separator;

the ash conveying device is a conveyer belt structure, and a slag pit is arranged at the tail end of the conveyer belt structure;

the cyclone separator is suspended from the roof beam.

Adopt the utility model discloses afterwards, the flue gas makes the large granule dust separated through cyclone earlier after coming out from horizontal flue, sees off via defeated grey equipment, and the flue gas of purification gets into dust collector from afterbody flue discharge, greatly reduced dust removal pressure, reduced dust collector area occupied.

fig. 2 is a bottom view of the present invention;

FIG. 3 is a schematic view of an ash conveying device.

Detailed Description

Referring to fig. 1, 2 and 3, a garbage furnace structure with a cyclone separator comprises a horizontal flue 1 and a tail flue 2, the cyclone separator 3 is arranged between the horizontal flue 1 and the tail flue 2, a flue gas inlet of the cyclone separator 3 is connected with the horizontal flue 1, a flue gas outlet of the cyclone separator 3 is connected with the tail flue 2, an ash conveying device 4 is arranged at the bottom of a dust outlet of the cyclone separator 3, which is commonly a conveying belt structure, a slag pit 5 is arranged at the tail end of the conveying belt structure, expansion joints 6 are arranged at the connection part of the cyclone separator 3 and the horizontal flue 1 and the connection part of the cyclone separator 3 and the tail flue 2, the expansion joints 6 can absorb the expansion difference between different devices caused by the hesitation of the temperature difference of the flue or different fixing modes, for example, the tail flue 2 is a supporting mode, and the horizontal flue is a suspension mode, and one expansion is upward, another expansion mode is downward. In the figure, 7 is a superheater, and 8 is an economizer.

The castable is laid on the inner wall of the cyclone separator 3, so that the abrasion of dust particles to the inner surface can be effectively prevented, and the service life is prolonged.

The utility model discloses an adjustment cyclone entry flue gas velocity of flow and the inside velocity of flow of separator can select suitable dust collection efficiency, and dust collection efficiency can reach more than 90% usually. Through the arrangement, the dust amount entering the tail flue gas purification device can be effectively reduced, so that the area of the dust removal device is greatly reduced.

Claims
