In order to solve above technical problem, the utility model provides a kind of salt bearing liquid wastes to burn and retracting device, comprise membrane wall furnace body, half-dried quench tower, venturi reactor, air-box type sack cleaner, spray scrubber, absorption tower and free-standing chimney, it is characterized in that: described membrane wall furnace body is connected with film-type wall boiler by membrane wall flue, described film-type wall boiler outlet flue is connected with half-dried quench tower air inlet, described half-dried quench tower top is provided with atomising device, the alkali lye that described atomising device is extracted in alkali lye pond by quench pump is atomized, be provided with waste liquid outlet bottom described half-dried quench tower and lead to blowdown pipeline, the gas outlet of described half-dried quench tower is connected with the air inlet of described venturi reactor, and the charge door of venturi reactor is provided with the discharger adding charcoal lime, and the air inlet of described venturi reactor is connected with Roots blower, the air inlet of described air-box type sack cleaner is connected respectively at described venturi reactor and air-introduced machine with gas outlet, and the ash hole of described air-box type bag-type dust installs discharger, the air outlet of described air-introduced machine is connected with described spray scrubber by pipeline, described spray scrubber gas outlet is connected with free-standing chimney by described scrubbing tower, the spray liquid that the spray equipment on described spray scrubber and absorption tower extracts in circulatory pool by spray pump sprays, and the bottom on described spray scrubber and absorption tower is provided with liquid outlet leads to described circulatory pool.
The technical scheme that the utility model limits further is: aforesaid salt bearing liquid wastes burns and retracting device, the air inlet of described air-box type sack cleaner is all connected with compressed air with gas outlet, in order to remove the dust in sack cleaner on cloth bag, improve the efficiency of dust collection of sack cleaner.
Aforesaid salt bearing liquid wastes burns and retracting device, and described spray scrubber is made up of the first scrubbing tower and the second scrubbing tower two-stage, and described second wash tower bottoms liquid outlet is connected with described first scrubbing tower top inlet.
Aforesaid salt bearing liquid wastes burns and retracting device, and in order to improve the atomizing effect of atomizer, the atomising device of described half-dried quench tower is connected with compressed air.
Aforesaid salt bearing liquid wastes burns and retracting device, and described air-introduced machine is provided with cooling water intake-outlet, for lowering the temperature to air-introduced machine.
Further, aforesaid salt bearing liquid wastes burns and retracting device, and described discharger is Star-like unloader.
The beneficial effects of the utility model are:
The utility model is undertaken burning and heat exchange by membrane type fireplace, effectively improves the utilization rate of waste heat of liquid waste incineration, can solve the susceptible to plugging defect of traditional burner shape simultaneously, and waste discharge ratio smoothly; Owing to adopting insulation material, greatly reduce the corrosivity of body of heater, improve the service life of body of heater, the salt content of recyclable 15%-20% in addition, reduces the cost of liquid waste processing.
