Modular equipment using solid waste catalytic pyrolysis to prepare high-value fuel gas

Abstract

The invention discloses modular equipment using solid waste catalytic pyrolysis to prepare high-value fuel gas. The equipment comprises a control module, a preprocessing module, a pyrolysis module, a secondary catalyzing module, a condensation module, a purification and absorption module, a liquid collecting module and a gas collecting module. The equipment has the advantages that corresponding modules are started and selected to work according the properties of to-be-processed materials and processing requirements, the control module is used to control the whole system, reaction device temperature, gas pressure and flow speed, multistage cooling system temperature, absorption liquid flow speed and reflux ratio, and the like are regulated to the required temperature, pressure and flow speed range, uniform heat transfer and mass transfer are achieved, gas and liquid products are stored in corresponding storage modules, and the high-value fuel gas is prepared through solid waste catalytic pyrolysis; the equipment using touch-screen operation is capable of dynamically displaying parameters such as temperature, pressure, flow speed and time, high in automation and intelligent level, simple and convenient in man-machine communication, capable of modularly designing and combining production processes according to the properties and processing degree of raw materials and product quality requirements, and efficiency and economy of a solid waste treatment process are increased.

Description

technical field

[0001] The invention belongs to the field of biochemical industry, in particular to a modular equipment for preparing high-value gas by catalytic pyrolysis of solid waste. Background technique

[0002] In recent years, with the rapid development of the economy, organic waste such as domestic waste, kitchen waste and sludge has shown a linear growth trend. On the other hand, with the depletion of fossil energy and the increasing air pollution, including walnuts Nut shells such as shells, coconut shells, almond shells, corn stalks, wheat straws, barley straws, rice straws, corncobs, bagasse, switchgrass, miscanthus, branches, wood chips and weeds, rice husks and other agricultural and forestry wastes. , Resource utilization has received unprecedented attention. At present, these solid wastes are usually disposed of by landfill, incineration, and composting. However, in addition to direct landfilling, in addition to producing a large amount of odor, high-concen...
