Abstract
The utility model relates to the field of smoke and dust cooling treatment techniques, in particular to a two-stage cooling treatment system. A trapezoidal lower pipe interface at the lower end of a closed first-stage cooling treatment device is hermetically welded on a dust discharge pipe in a hearth. Smoke pipes are equally distributed in the first-stage cooling treatment device. A water flowing passage is arranged around the smoke pipes. A water level gauge is installed on the outer side of the first-stage cooling treatment device. A water inlet pipe is installed below the other side of the first-stage cooling treatment device. A water drain pipe is installed above the other side of the first-stage cooling treatment device. One end of a communicating pipe is hermetically welded at a trapezoidal upper pipe interface at the upper end of the first cooling treatment device.

The technical scheme that the utility model adopts is achieved in that secondary cooling treatment system, comprise first order cooling processor and economizer, the pipe joint seal welding is on the dust discharge pipeline of burner hearth under the trapezoidal shape of airtight first order cooling processor lower end, the inner average mark of first order cooling processor is furnished with vertical smoke pipe, be water stream channel around the vertical smoke pipe, a water level meter is housed in the outside of first order cooling processor, below first order cooling processor opposite side, water inlet pipe is housed, drainpipe is equipped with in the top, seal welding connecting pipe in pipe joint place on the trapezoidal shape of first order cooling processor upper end, the other end seal welding of connecting pipe is on pipe joint on the economizer.
Be welded on the dust discharge pipeline of burner hearth to the trapezoidal short circuit mouth sealing of the following pipe joint of described first order cooling processor, trapezoidal long interface sealing of pipe joint is welded on the bottom of first order cooling processor under it, be welded on to the trapezoidal long interface sealing of pipe joint the top of first order cooling processor on it, be welded on the connecting pipe that connects economizer to the trapezoidal short circuit mouth sealing of pipe joint on it.
Described first order cooling processor divides the rectangular structure close around being, is evenly distributed with 100-150 corresponding up and down circular hole on its end face and the bottom surface, the vertical smoke pipe that setting and end face and bottom surface seal mutually between the circular hole up and down of end face and bottom surface correspondence.
The water level meter in the described first order cooling processor outside is communicated with the water stream channel outside its smoke pipe, and water level meter bottom is corresponding with the water inlet pipe position, and water level meter top is corresponding with the drainpipe position.
Described economizer is the same with first order cooling processor shape, its end face and bottom surface are not sealed, end face be connected on the connecting pipe after pipe joint on it is communicated with, the bottom surface is connected on the dust discharge pipeline after pipe joint is communicated with down with it, the water pipe that its inside is evenly distributed is the water pipe that horizontal direction is arranged, is interconnected, and is smoke dust duct around the water pipe.
Secondary cooling treatment system of the present utility model, compare with traditional high-temperature smoke cooling smoke evacuation system, the design of first order cooling processor, the contact area of flue dust and current is increased, cooling-down effect to flue dust improves greatly, pass through economizer again behind the flue dust process first order cooling processor, temperature can be down to 70-80 degree centigrade, has improved the security of working equipment and the efficient of boiler.
