Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1

If fig. 1, a leading heat dissipation casing of sack cleaner, including heat dissipation case 3, be equipped with on heat dissipation case 3 and supply the flue gas to get into heat dissipation case 3's air inlet cylinder 1 and the gas outlet of exhaust flue gas, inside boiler exhaust high temperature waste gas got into heat dissipation case 3 through air inlet cylinder 1, heat dissipation case 3 and the contact of high temperature waste gas can absorb its heat, release the atmosphere through heat dissipation case 3, reach the effect of carrying out the preliminary cooling processing to waste gas.

The inside three interception board 4 of being no less than that is equipped with of heat dissipation case 3, the air inlet of heat dissipation case 3 corresponds with the foremost interception board 4 in inside position, and after waste gas got into heat dissipation case 3, mobile waste gas can collide with interception board 4, and large granule and mars lost kinetic energy free fall when striking interception board 4 in making waste gas and put out a fire, reach large granule and mars filterable effect in the waste gas, also have certain buffering effect to gaseous flow.

As shown in fig. 4, the interception plate 4 is uniformly provided with flow guide holes, the flue gas collides with the interception plate 4 after entering the heat dissipation box 3, part of the gas is guided through the flow guide holes on the interception plate 4, the flow guide plates inclined from top to bottom are arranged in the flow guide holes, and part of the gas flow is changed in flow direction under the action of the flow guide plates when the gas flow passes through the flow guide holes, so that the effect of uniform distribution of the gas flow is achieved.

The interception plate 4 is arranged in the heat dissipation box 3 in a staggered manner. Both ends of the interception plate 4 extend to opposite sides of the heat dissipation case 3. The flue gas collides with the interception plate 4 after entering the heat dissipation box 3, one part of gas flows in a guiding mode through the flow guide holes in the interception plate 4, the other part of gas flows in a guiding mode through the channel formed by the interception plate 4 and the interception plate 4 in a staggered mode, the flow direction of the flue gas is changed through the coordination of the interception plate 4 which is staggered up and down and the flow guide holes arranged in the interception plate 4, the flowing of the gas is more uniformly distributed, and a certain flow buffering effect is achieved.

The flow speed of the waste gas entering the heat dissipation box 3 is very fast, and the inner diameter of the air inlet cylinder 1 is gradually increased along with the air inlet direction, so that the flow speed of the gas can be gradually reduced, and the kinetic energy of the fly ash is reduced. All be equipped with circular arc guide plate 2 through the inside edges and corners department at heat dissipation case 3, can prevent effectively that the flue gas from at the inside vortex that forms of heat dissipation case 3, because the increase of air flow sectional area makes the air velocity reduce at this in-process, great granule can be under the effect free fall of gravity in the smoke and dust, reaches the effect of dust fall in advance to the waste gas smoke and dust.
