Incineration technology system for petrochemical cured materials

Abstract

The invention discloses an incineration technology system for petrochemical cured materials. The incineration technology system comprises an incinerator and a mixing device, wherein the mixing device is connected with a solid waste incoming pipe; an outlet end of the mixing device is connected with a feeding opening of a primary combustion zone of the incinerator; a metering component is arranged on the outlet end of the mixing device; a primary air duct is arranged on the primary combustion zone of the incinerator; a secondary air duct is arranged on a secondary combustion zone of the incinerator; the metering component is interlocked with a primary air duct air volume valve and a secondary air duct air volume valve; a PSA adsorption device is arranged at the front end of the secondary air duct; and secondary air is fed into the secondary combustion zone of the incinerator after passing through the PSA adsorption device. According to the incineration technology system, after the mixing device uniformly mixes the petrochemical solid waste, the mixed petrochemical solid waste is fed into the incinerator through the metering component, air is fed into the primary combustion zone, rich oxygen prepared through the PSA adsorption device is fed into the secondary combustion zone, the metering component can perform interlocking control on air inlets of the primary air duct and the secondary air duct, the oxygen content inside the incinerator is reasonably controlled, full combustion is achieved, and the tail gas purification pressure is reduced.

Description

technical field [0001] The invention relates to an incineration process system for petrochemical solidified matter, in particular to an incineration process for waste such as solid waste residue and waste liquid in the petrochemical industry, and belongs to the technical field of petrochemical industry. Background technique [0002] With the continuous development of modern industry, the demand for petroleum is also increasing, followed by the generation of various petrochemical wastes. In modern industry, petrochemical waste is usually treated by incineration. The incineration method is a comprehensive process of pyrolysis and deep oxidation. Petrochemical waste can be completely oxidized and decomposed by incineration, thereby reducing the volume of waste, eliminating toxic and harmful substances, Multiple purposes of recovering usable energy and protecting the environment. [0003] For the incineration treatment process of petrochemical solid waste, the following situati...

Problems solved by technology

[0004] 1) The incineration equipment adopts the rotary kiln incinerator, such as "Petrochemical Environmental Protection" ("A Brief Discussion on the Incineration Treatment Technology of Chemical Waste", Volume 26, No. 1, 2003, 43-44), through the rotary incineration equipment. The petrochemical wastes in it are mixed, and the actual operation process has defects such as high equipment investment, low thermal efficiency, long start-up and shutdown time;

[0005] 2) A large amount of petrochemical solid waste, such as: waste liquid, solid waste residue, sludge, etc., is sent to the incineration device, and it is incinerated at high temperature. During the incineration process, the petrochemical solid waste is not burned uniformly, which will reduce the combustion efficiency and cause incineration. The excess of CO in the exhaust gas of the device affects the treatment pressure of the exhaust gas
