The technical problems to be solved in the utility model is to provide a kind of chilling apparatus that flue-gas temperature can be made stable.
In order to solve above-mentioned technical problem, the technical solution of the utility model is a kind of chilling apparatus, including at least two flash cold columns,
Connected by communicating pipe between described flash cold column；Also include nozzle, water tank and air accumulator；Described nozzle is removably connected to described
On flash cold column, and the mouth of nozzle is positioned at described flash cold column；Described nozzle is connected with described water tank and air accumulator respectively by pipeline
Connect；Air inlet pipe and escape pipe is offered on described flash cold column.
Further, the tower wall of described flash cold column includes stainless steel layer, the ramming bed of material and fire brick layer the most from outside to inside.
Further, described flash cold column offers manhole.
Further, the bottom in described flash cold column is provided with ash bucket；Described ash bucket is removably connected on described flash cold column.
Further, drain pipe is also included；One end of described drain pipe is communicated on described ash bucket, away from one end of described ash bucket
Pass described flash cold column.
Further, the pipeline connecting described nozzle and water tank arranges water pump.
Further, filter is also included；Described filter is connected to described air accumulator by pipeline.
Use technique scheme, by arranging the flash cold column of more than two, be avoided that flue-gas temperature is fluctuated, from without
Damage flue gas cooling and purifying system, make system preferably even running.

Wherein, 1-flash cold column, 2-communicating pipe, 3-nozzle, 4-water tank, 5-air accumulator, 6-filter, 7-water pump, 8-air inlet
Pipe, 9-manhole, 10-drain pipe, 11-ash bucket, 12-escape pipe, 13-stainless steel layer, the 14-ramming bed of material, 15-fire brick layer.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.At this it should be noted that for this
The explanation of a little embodiments is adapted to assist in and understands this utility model, but is not intended that restriction of the present utility model.Additionally, below
Just can be mutual as long as technical characteristic involved in described each embodiment of this utility model does not constitutes conflict each other
Combination.
As shown in Figure 1-2, a kind of chilling apparatus, including at least two flash cold columns 1, between flash cold column 1 by communicating pipe 2 even
Connect；Also include nozzle 3, water tank 4 and air accumulator 5；Nozzle 3 is removably connected on flash cold column 1, and the mouth position of nozzle 3
In flash cold column 1；Nozzle 3 is connected with water tank 4 and air accumulator 5 respectively by pipeline；Air inlet pipe 8 is offered on flash cold column 1
With escape pipe 12.
Concrete, the external diameter of flash cold column 1 is 2.6m, and effective depth is 14m.
Owing to flue gas after medical wastes incineration containing HCl and SO2Deng gas, inevitably result from after water-spraying control
A small amount of acidic materials, corrode generation apparatus body, especially HCl gas, and the dilute hydrochloric acid formed after meeting water will to steel
Produce corrosion greatly.Therefore, the tower wall of flash cold column 1 includes stainless steel layer 13, the ramming bed of material 14 and resistance to the most from outside to inside
Firebrick layer 15, can effectively prevent corrosion, moreover it is possible to play the effect of insulation.
For convenience of maintenance, flash cold column 1 offers manhole 9.
Bottom in flash cold column 1 is provided with ash bucket 11；Ash bucket 11 is removably connected on described flash cold column 1, and convenient reception is sprayed
The dust drenched and alkali liquor.
Discharge for convenience of by the waste liquid in ash bucket, also include drain pipe 10；One end of drain pipe 10 is communicated on ash bucket 11, far
Passing flash cold column 1 from one end of described ash bucket 11, the device that can dispose waste liquid with other connects.
The pipeline connecting described nozzle 3 and water tank 4 arranges water pump 7.
For ensureing the quality of air, do not contain dust etc., also include filter 6；Filter 6 is connected to air accumulator 5 by pipeline.
Use double tower cooling quenching: once cooling guarantees high-temperature flue gas (800 DEG C～1000 DEG C) by water, gas, atomization, fall
Temperature is at 550 DEG C-600 DEG C；Secondary flash cold column passes through water, gas, atomization, and exiting flue gas controls at 160 DEG C～180 DEG C, is formed dry
Flue gas constant temperature, had the most both ensured that the tail gas clean-up in specification avoided 200 DEG C～500 DEG C of intervals, had effectively contained dioxin, again can be true
Protect and enter cloth bag bin flue gas constant temperature dry flue gas, thus ensure effective operation of whole system.In use, by compressed air by water
Be atomized into the most small water smoke, make water smoke completely vaporize within the time of 1.5 seconds so that flue-gas temperature also in 1.5s from
It is down to 200 DEG C for 550 DEG C.Flash cold column uses constant voltage operation, and the most compressed-air actuated pressure is constant, compressed air and the flow of water and mist
The pressure changing water is automatically adjusted with the fluctuation of outlet temperature, to ensure that exit gas temperature is constant in set point.
Nozzle uses the automatic single-hole nozzle of water-air two phase flow, nozzle diameterMaterial is 316L, and the ability of nozzle can meet
Design requirement, i.e. 500kg～1600kg/h nozzle, the water particle diameter after this nozzle atomization is the least, and narrow distribution range
(mean diameter 50 μm, maximum particle diameter is less than 300 μm), can completely vaporize within the extremely short time, and vaporization time is less than 1.5s.
Above in association with accompanying drawing, embodiment of the present utility model is explained in detail, but this utility model is not limited to described reality
Execute mode.For a person skilled in the art, in the case of without departing from this utility model principle and spirit, real to these
The mode of executing carries out multiple change, revises, replaces and modification, still falls within protection domain of the present utility model.
