Embodiment 2

[0031] The sewage treatment system includes a primary sedimentation tank 11, a reaction sedimentation tank 12, a gray water collection tank 13 and a filter feeding tank 14. The upper outlet of the primary sedimentation tank 11 is connected to the reaction sedimentation tank 12, and the upper outlet of the reaction sedimentation tank 12 is drained through The pump is connected to the gray water collection tank 13. The outlet of the gray water collection tank 13 is connected to the gasification section. The outlet at the bottom of the primary settling tank 11 is connected to the filter feed tank 14, the outlet of the filter feed tank 14 is connected to the filter feed pump, and the outlet of the filter feed pump is connected to the roughing filter. Reactive precipitation is carried out in the ordinary sedimentation and flocculation treatment process to reduce the content of Ca2+ and Mg2+ ions in the water and avoid scaling of pipelines.

Embodiment 3

[0033] Different from Embodiment 2, the primary settling tank 11 is connected to the flocculant-adding pipeline, the reaction settling tank 12 is provided with an agitator, and the top is connected to the NaOH pipeline, NaOH pipeline, and NaOH pipeline. 2 CO 3 Pipes and flocculant pipes.

Embodiment 4

[0035] Different from Embodiment 1, a condenser is provided between the heating heat exchanger 5 and the cooling row pipe 8 . The cooling efficiency in the hot water tower 6 can be improved.

Abstract

The invention discloses a Texaco gasifier black water heat recovery and treatment system. The Texaco gasifier black water heat recovery and treatment system comprises a multistage flash evaporator system and a flash evaporation heat exchange system, the multistage flash evaporator system comprises a high-pressure flash evaporation tank, a low-pressure flash evaporation tank and a vacuum flash evaporation tank, the flash evaporation heat exchange system comprises a compressor, a cooling grid and a heating heat exchanger, the gas phase outlet of the high-pressure flash evaporation tank is connected with the gas phase inlet of a hot water tower, the cooling rid is arranged in the hot water tower, the outlet of the cooling grid is connected with the inlet of the heating heat exchanger through a pipeline, and the inlet of the cooling grid is connected with the refrigerant outlet of the heating heat exchanger; the liquid phase outlet of the high-pressure flash evaporation tank is connected with the liquid inlet of the heating heat exchanger, the liquid outlet of the heating heat exchanger is connected with the inlet of the low-pressure flash evaporation tank, and the liquid phase outlet of the low-pressure flash evaporation tank is connected with the inlet of the vacuum flash evaporation tank. The flash evaporation heat exchange system absorbs heat in the hot water tower and uses the absorbed heat to heat blank water among the flash evaporation tanks, so the heat recycling efficiency is high, and the gas-liquid conversion efficiency in the hot water tower is increased.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a black water heat recovery treatment system for a Texaco gasifier. Background technique [0002] In recent years, my country's new coal chemical industry, which mainly produces clean energy (such as hydrogen, methane, methanol, etc.) or replaces petrochemical products (such as ethylene raw materials, polypropylene raw materials, dimethyl ether, etc.), has a strong momentum of development. Among them, Texaco (GE) coal-water slurry gasification technology is one of the more successful coal gasification technologies at home and abroad, and has a history of more than 30 years in my country. GE gasifier is the core equipment of Texaco coal-water slurry pressurized gasification device. It includes two parts: combustion chamber and quenching chamber. The upper part is the combustion chamber and the lower part is the quenching chamber. , rising pipe and baffle baffle and other...
