Embodiment Construction

[0036] The system and method for pyrolyzing oil and gas purification of high-temperature domestic waste according to the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] Such as figure 1 As shown, a purification system for pyrolysis oil and gas of high-temperature domestic waste of the present invention comprises a cyclone dust collector 1, a decoking cooler A2, a fan A3, a decoking cooler B4, a fan B5, a water washing tower 6, an alkali washing tower 7, Tar coalescer A8, tar filter A9, tar filter B10, tar coalescer B11 and tar storage tank 12;

[0038] Among them, the pyrolysis gas first enters the cyclone dust collector 1, the top of the cyclone dust collector 1 is connected to the top of the decoking cooler A2, the bottom of the decoking cooler A2 is connected to the upper part of the tar filter A9, and the lower part of the tar filter A9 is connected to to the tar storage tank 12;

[0039]The bottom of th...

Abstract

The invention belongs to the technical field of solid waste pyrolysis and energy application thereof, and particularly relates to a system and method for purifying high-temperature household garbage pyrolysis oil gas. According to the technical scheme, high-temperature pyrolysis gas passes through the cyclone dust collector, and most of fly ash is separated. Pyrolysis gas passes through a second-stage cooling decoking device and a tar coalescer, the tar removal precision is high, the tar oil content in the pyrolysis gas is small, and the possibility of carbon deposition in the storage and use process of the pyrolysis gas is reduced; one part of a cooling medium for cooling the decoking device is air, and the other part of the cooling medium is purified pyrolysis gas, so that the method has the following technical effects that waste water generated by spray cooling in a common process is not generated; the problems that two or more coolers are connected in series, the occupied area is large, and piping between the coolers is complex are solved; and part of heat in the pyrolysis gas is recycled, the temperature of the purified pyrolysis gas is increased, and the combustion efficiency is improved for combustion.

Description

technical field [0001] The invention belongs to the technical field of solid waste pyrolysis and its energy application, and in particular relates to a system and method for pyrolyzing oil and gas purification of high-temperature domestic waste. Background technique [0002] At present, the disposal of municipal solid waste has become the focus of public attention. The existing treatment methods for domestic waste include landfill, composting, incineration and other technologies, but due to the limitations of the technology itself, it brings pollution to the land, water, and air, especially the dioxin produced by incineration, which is harmful to human health. Great threat. With the improvement of environmental protection requirements, more and more attention has been paid to the use of pyrolysis technology to treat domestic waste. This method eliminates the generation of dioxins, and the generated pyrolysis oil, pyrolysis gas, and pyrolysis residual carbon can all be used ...
