Abstract
A swirler adjusting device belongs to the technical field of four air channel pulverized coal burner used in the cement industry. The device comprises a swirl air pipe and a fixed central air pipe, wherein the swirl air pipe is fixedly connected with a third flange, an adjustable central air pipe is sleeved outside the fixed central air pipe, and is hermetically connected with the fixed central air pipe; one end of the adjustable central air pipe is fixedly connected with a second flange, the other end thereof is fixedly connected with a connecting pipe, and the third flange is connected with the second flange through an adjusting screw rod. The adjustable central air pipe can slide on the fixed central air pipe through the adjustment of the length of the adjusting screw rod, the swirler connected to the foremost end of the adjustable central air pipe is driven to move, and therefore, the swirl strength adjustment of the swirler is realized. The burner can ensure the pulverized coal to be fully burnt, so as to ensure the pollution to the atmospheric environment to be reduced to the minimum.
Description
Technical field
The utility model relates to the technical field of cement industry with four-channel coal burner.
Background technology
The cement industry four-channel coal burner is one of the key equipment in cement plant, and the quality of this equipment performance directly has influence on product quality, environmental protection, energy resource consumption and the economic benefit in cement plant.The operation principle of coal burner is to utilize high-speed jet wind (exogenous wind) and high-speed rotational wind, center wind and the low speed wind of delivering coal to form the high speed difference jet, make the air-flow conversion and the mixed performance of burner front portion reach optimization, thus form evenly deliver coal, fully burning, controllable combustion flame.
At present, the cyclone of four-channel coal burner is subjected to structural limitations, and is unadjustable, that is the eddy flow length of eddy flow wind, intensity are unadjustable in cement production process, can not reach optimization.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of cyclone adjusting device to be provided, can regulate the eddy flow length and the intensity of cyclone, coal dust can being fully burned.
The purpose of this utility model is achieved in that the cyclone adjusting device, comprise eddy flow airduct and fixing central air hose, the eddy flow airduct is fixedlyed connected with the 3rd flange, outside fixing central air hose, be with adjustable central air hose, fixing central air hose and adjustable central air hose are tightly connected, one end of adjustable central air hose is fixedlyed connected with second flange, and the other end is fixedlyed connected with tube connector, and the 3rd flange is connected by adjusting screw(rod) with second flange.
The beneficial effects of the utility model are: by above design, central air hose is designed to " adjustable central air hose " and " fixing central air hose " two parts by original uncontrollable one.Adjustable central air hose can slide by the length of adjustment adjusting screw(rod) on fixing central air hose, drives the cyclone that adjustable central air hose connects foremost and moves sliding scale 〉=30cm.Thereby realized the swirl strength of cyclone and the adjusting of intensity, this burner can make coal dust obtain the burning of fullest, thereby makes its pollution to atmospheric environment can drop to minimum level.
For the utility model is sealed more, outside adjustable central air hose, be provided with first flange, first flange is connected by adjusting screw(rod) with the 3rd flange, seals by first sealing gland and first sealing ring between first flange and the adjustable central air hose.
In like manner, between second flange and the fixing central air hose by second sealing gland and the sealing of second sealing ring.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure, 1 tube connector, 2 eddy flow airducts, 3 the 3rd flanges, 4 first flanges, 5 adjusting screw(rod)s, 6 second flanges, 7 central air hoses of fixing, 8 center wind inlets, 9 second sealing glands, 10 second sealing rings, 11 first sealing glands, 12 first sealing rings, 13 adjustable central air hoses.
The specific embodiment
As shown in Figure 1, the cyclone adjusting device comprises eddy flow airduct 2 and fixing central air hose 7, and eddy flow airduct 2 is fixedlyed connected with the 3rd flange 3, and fixing central air hose 7 is provided with center wind inlet 8.
Be with adjustable central air hose 13 outside fixing central air hose 7, fixing central air hose 7 is tightly connected with adjustable central air hose 13.
One end of adjustable central air hose 13 is fixedlyed connected with second flange 6, the other end be connected 1 fixedly connectedly, tube connector 1 is connected with cyclone.Outside adjustable central air hose 13, be provided with first flange, 4, the three flanges 3, first flange 4 is connected by adjusting screw(rod) 5 with second flange 6.
Seal by first sealing gland 11 and first sealing ring 12 between first flange 4 and the adjustable central air hose 13.Seal by second sealing gland 9 and second sealing ring 10 between second flange 6 and the fixing central air hose 7.
