Abstract

The invention discloses a device for treating high-concentration organic wastewater through catalytic hydrothermal gasification. The device mainly comprises a CHG reactor, a wastewater temporary storage tank and a condensation heat exchanger, wherein the CHG reactor mainly comprises a shell, a thermocouple, a water distribution device and a filler bracket, the shell is provided with a feed port and a gas outlet, the filler bracket is used for supporting a catalyst filler and is arranged in the shell, the water distribution device is arranged in the shell above the catalyst filler, and the thermocouple is inserted into the side wall of the shell and extends into the catalyst filler. The condensation heat exchanger is communicated with the air outlet through a back pressure valve and a pipeline, the liquid inlet of the wastewater temporary storage tank is connected with the condensation heat exchanger through a high-pressure feeding pump and a pipeline, and the liquid outlet of the wastewater temporary storage tank is connected with the feeding port through the high-pressure feeding pump and a pipeline. The device can quickly convert high-concentration organic wastewater into clean energy or harmless gas at a low temperature under the action of a catalyst, greatly reduces the energy consumption in the treatment process, improves the treatment efficiency, and has potential application prospects.

Description

technical field

[0001] The invention relates to the technical field of wastewater treatment equipment, in particular to a catalytic hydrothermal gasification device for treating high-concentration organic wastewater. Background technique

[0002] Industrial production has become an important part of driving economic development, but the "three wastes" produced in the industrial production process will also cause very serious environmental problems. Among them, industrial organic wastewater, especially high-concentration organic wastewater that is difficult to biodegrade has become a recognized problem in the environmental field. Especially in recent years, with the development of large-scale and integrated industrial production, the types and discharges of waste water have been increasing, and the pollution of water bodies has become increasingly widespread and serious, seriously threatening human health. Therefore, it is of great significance to develop new high-concentrat...
