Because the industries of coal gasification, coal-to-methanol and coal-to-caprolactam and the like involve some high-toxicity wastewater, the treatment difficulty of sludge is very high. Part of sludge belongs to hazardous waste and needs to be treated by an external commission unit with hazardous waste treatment qualification.
The wet oxidation method is to oxidize organic pollutant into CO in liquid phase under high temperature (150-320 deg.C) and high pressure (0.5-10 MPa) with air or oxygen as oxidant 2 And H 2 O and other inorganic matters or small molecule organic matters. The method has remarkable effect on treating high-concentration organic wastewater, wastewater and sludge containing toxic substances and substances difficult to biodegrade, and compared with the traditional biological treatment method, the wet oxidation method has the advantages of high efficiency, energy conservation, no secondary pollution and the like.

The aim of the utility model can be achieved by the following technical scheme:
a wet oxidation treatment device for coal chemical sludge: the coal chemical industry sludge concentrated solution enters the wet oxidation reaction kettle through a feed pipe (1), oxygen is used as an oxidant and enters the wet oxidation reaction kettle through an air inlet pipe (2), a bent pipe area (3) is arranged in the sludge concentrated solution entering the wet oxidation reaction kettle, and the discharged material is discharged through a discharge pipe (4) after the wet oxidation reaction.
The inside of the treatment device is extended from the feed pipe (1) to the inside of the wet oxidation reaction kettle to form a bending pipe area (3).
The bent pipe area (3) is formed by a pipeline with the same inner diameter as the feeding pipe.
The bent pipe area (3) comprises 3-10 elbows.
The working principle of the utility model is as follows:
the coal chemical industry sludge concentrated solution enters the wet oxidation reaction kettle through a feed pipe (1), oxygen is used as an oxidant and enters the wet oxidation reaction kettle through an air inlet pipe (2), a bent pipe area (3) is arranged in the sludge concentrated solution entering the wet oxidation reaction kettle, and the discharged material is discharged through a discharge pipe (4) after the wet oxidation reaction.
Compared with the prior art, the utility model has the advantages that:
(1) Because the bent pipe area is arranged in the wet oxidation reaction kettle, the fed sludge concentrated solution is liquefied in the pipeline of the bent pipe area, and the solid-liquid phase is converted;
(2) The materials at the outlet of the pipe in the pipe bending zone enter the reaction kettle to be basically liquid, so that the residence time in the wet oxidation reaction kettle can be greatly shortened, and the operation cost is saved.
