Oily pollutant ultraclean treatment process and oily pollutant ultraclean treatment equipment

Abstract

The invention provides an oily pollutant ultraclean treatment process and oily pollutant ultraclean treatment equipment, and relates to the technical field of oily pollutant ultraclean treatment. Theoily pollutant ultraclean treatment equipment comprises a crusher, a feeder, a thermal desorption furnace, a combustion fan, an oil-gas dust collector, a combustion-supporting air heater, an oil-gas two-phase separator, an oil-gas condenser, a three-phase separator, a non-condensable gas buffer tank, an oil phase buffer tank, a wastewater tank, a high temperature heat conductive oil storage tank,a generator set, a low temperature heat conductive oil storage tank and a distributed control system (DCS) intelligent autonomous control system. Oily pollutants are quantitatively conveyed to the feeder in an airtight way through a pipeline after being crushed by means of the crusher, and is then transported to a thermal desorption device, so that the labor intensity is lightened; an anaerobic thermal desorption reaction is realized by means of high temperature anaerobic operation; the non-condensable gas is recycled as fuel; the total petroleum hydrocarbon (TPH) of the treated solid phase residue is less than 0.05 percent; a closed dry slagging technology is adopted, so that clean discharge of the residue is realized; a flue gas waste heat recovery heat exchanger and the oil-gas condenser are used for realizing waste heat recovery; after the generator set is used for power generation for reuse, the recovery utilization rate of the waste heat can reach 90%.

Description

technical field [0001] The invention relates to the technical field of ultra-clean treatment of oily pollutants, in particular to a process and equipment for ultra-clean treatment of oily pollutants. Background technique [0002] Currently, a large amount of oily pollutants produced in the oil and gas production chain is an unavoidable problem in the petroleum industry. Oily pollutants have caused great harm to the environment and human health, and urgently need effective and sustainable treatment. Among them, sludge pyrolysis has been implemented worldwide, and various heating furnaces are used to separate hydrocarbons from oily pollutants. However, the pyrolysis process and equipment are intermittent and discontinuous, with low efficiency, high safety risks, and high energy consumption. Issues such as large emissions. Contents of the invention [0003] The present invention provides a process and equipment for ultra-clean treatment of oily pollutants for the above-ment...
