Supercritical flashed and pyrolyzed gas material condensation and reduction device

Abstract

The invention discloses a supercritical flashed and pyrolyzed gas material condensation and reduction device. The device mainly comprises a molten salt tank, an insulating layer, a combustion chamber,an ash discharging funnel, an annular afterheat recycling tank, a dedusting air preheater, a fluidized combustion tube, a gas conveying pipe, a fuel conveyor, a primary blower, a secondary blower, athree-return stroke heat exchange flue pipe, a first flue gas tank, a second flue gas tank, a third flue gas tank, a first heat exchange flue pipe, a second heat exchange flue pipe, a soft water treater, a preheated water coil, a water tank, a high-pressure plunger pump, a high-pressure spraying device, a steam generator, a first steam coil, a second steam coil, a sub-cylinder, a material conveyer, a material pyrolyzing coil, a decomposing chamber, a cooling tower, a coal slurry tank, a flashing and pyrolyzing gas coil, an overheating tube and the like. The device has the advantages as follows: 1, superheated steam is instantly produced, and the heat efficiency is extremely high; 2, the steam temperature and the steam pressure can be adjusted; 3, coal reacts with the steam to produce watergas, combustion is efficient and clean, and pollution is free; and 4, multi-stage afterheat recycling is achieved, and the smoke exhaust temperature is low.

Description

technical field [0001] The invention relates to a boiler. Specifically, it is a supercritical flash pyrolysis coal gas substance condensation reduction device. Background technique [0002] The whole world has been studying how to improve the thermal efficiency of the boiler body to save natural resources. Generally, it is the research on the manufacturing materials and the way of fuel entry, and then gradually produces subcritical, supercritical, and ultra-supercritical. Boiler, but it has not broken through the basic structure of the boiler and the way of steam water supply. At present, it still stays in the state of the traditional heating mode and the steam production mode of boiling bubbles. [0003] Traditional boilers are bulky and complex in structure, the steam water supply method is backward, the boiler startup and shutdown consumes a lot of energy, the operation is complicated and takes a long time, the selection and application of heat transfer medium is unreaso...
