Description
Technical Field
The utility model belongs to the technical field of cooling of kiln flues, and particularly relates to a water-cooling sleeve device for a kiln flue.
Background
At present, flue gas generated by an industrial kiln is subjected to dust removal treatment, a cloth bag dust remover is generally used for dust removal, but the highest heat-resistant temperature of a dust removal cloth bag is only about 200 ℃, and in order to ensure the normal operation of the cloth bag dust remover, the high-temperature flue gas generated by the industrial kiln needs to be reduced from 1000 ℃ to below 200 ℃, and then the dust removal work can be carried out through the cloth bag dust remover.
At present, two main modes of flue gas cooling are adopted, namely, the first mode is to increase the length of a kiln flue, and the second mode is to increase an air mixing valve on the kiln flue.
For the first mode, the purpose of cooling the flue gas to below 200 ℃ is achieved mainly by increasing the heat dissipation time of the flue gas in the flue of the kiln, but the increase of the length of the flue of the kiln inevitably increases the occupied area of the production land, so that the cost is increased.
For the second mode, the flue gas is cooled mainly by mixing cold air into the flue gas, but the pressure of the whole system is changed due to the increase of the air mixing valve, so that the normal production balance is affected.
Disclosure of utility model
Aiming at the problems existing in the prior art, the utility model provides the water-cooling sleeve device for the kiln flue, which can reduce the length of the kiln flue, reduce the occupation of production land, reduce the cost, ensure the production balance of the system because no air leakage point exists on the flue, effectively improve the cooling effect of the kiln flue through the double cooling effect of cooling water and cooling fins, and prevent uneven heat exchange caused by short circuit of water flow by the spiral water guide fins, so that the cooling effect of the kiln flue is further improved.
In order to achieve the above purpose, the present utility model adopts the following technical scheme: a water-cooling sleeve device of a kiln flue comprises a water-cooling sleeve and a spiral water guide blade; the spiral water guide blades are welded and fixed on the outer surface of the kiln flue, the water cooling sleeve is coaxially sleeved outside the kiln flue, and the circumferential edges of the spiral water guide blades are tightly attached to the inner surface of the water cooling sleeve; and the flue penetrating holes in the centers of the pipe walls at the two ends of the water-cooling sleeve are welded, sealed and fixed with the kiln flue.
The cooling water inlet of the water-cooling sleeve is arranged on the pipe wall at one end of the sleeve, and the cooling water outlet of the water-cooling sleeve is arranged on the pipe wall at the other end of the sleeve.
And a cooling fin is welded and fixed on the outer surface of the water-cooling sleeve.
The utility model has the beneficial effects that:
The water-cooling sleeve device for the kiln flue can reduce the length of the kiln flue, reduce the occupation of production land, reduce the cost, ensure the production balance of the system because of no air leakage point on the flue, effectively improve the cooling effect of the kiln flue by the double cooling effect of cooling water and cooling fins, and prevent uneven heat exchange caused by short circuit of water flow by the spiral water guide blades so as to further improve the cooling effect of the kiln flue.

FIG. 1 is a schematic diagram of a water-cooled jacket device for a kiln flue according to the present utility model;
In the figure, 1-water-cooling sleeve, 2-spiral water guide blades, 3-kiln flue, 4-cooling water inlet, 5-cooling water outlet and 6-cooling fins.
Detailed Description
The utility model will now be described in further detail with reference to the drawings and to specific examples.
As shown in fig. 1, a water-cooling sleeve device for a kiln flue comprises a water-cooling sleeve 1 and a spiral water guide blade 2; the spiral water guide blades 2 are welded and fixed on the outer surface of the kiln flue 3, the water cooling sleeve 1 is coaxially sleeved on the outer side of the kiln flue 3, and the circumferential edges of the spiral water guide blades 2 are tightly attached to the inner surface of the water cooling sleeve 1; and a flue penetrating hole in the center of the pipe wall at the two ends of the water-cooling sleeve 1 is welded, sealed and fixed with the kiln flue 3.
The cooling water inlet 4 of the water-cooling sleeve 1 is arranged on the pipe wall at one end of the sleeve, and the cooling water outlet 5 of the water-cooling sleeve 1 is arranged on the pipe wall at the other end of the sleeve.
And cooling fins 6 are welded and fixed on the outer surface of the water-cooling sleeve 1.
The following describes a one-time use procedure of the present utility model with reference to the accompanying drawings:
When the water cooling sleeve device is adopted in the kiln flue 3, high-temperature flue gas generated by an industrial kiln is discharged through the kiln flue 3, heat of the flue gas is firstly transferred to the kiln flue 3 and the spiral water guide blades 2, the spiral water guide blades 2 at the moment are equivalent to the increase of the heat dissipation area of the kiln flue 3, cooling water flows spirally under the guidance of the spiral water guide blades 2 along with the cooling water introduced from the cooling water inlet 4 of the water cooling sleeve 1, heat exchange is carried out between the cooling water and the kiln flue 3 and the spiral water guide blades 2, the temperature of the flue gas is gradually reduced, and the temperature of the cooling water is increased until the cooling water subjected to heat exchange is discharged from the cooling water outlet 5 of the water cooling sleeve 1.
In the spiral flowing process of the cooling water, the heat carried by the cooling water can be further transferred to the water-cooling sleeve 1 and the cooling fins 6, natural heat dissipation is realized, heat dissipation is enhanced, and the cooling efficiency of the flue gas is further improved. Finally, after the high-temperature flue gas is subjected to the double cooling actions of the cooling water and the cooling fins 6, the aim of cooling to below 200 ℃ can be efficiently achieved.
