Rice hull carbonization secondary combustion recycler

Abstract

A rice hull carbonization secondary combustion recycler comprises a horizontal chain boiler. A collector is arranged on the periphery of the bottom of the horizontal chain boiler, an outlet is arranged at the bottom of the collector, a transverse auger is disposed below the outlet and connected with a transverse auger motor, an input end of a longitudinal auger is arranged at an output end of the transverse auger, an output end of the longitudinal auger is disposed above a coal hopper of the horizontal chain boiler, the longitudinal auger is connected with a longitudinal auger motor, after dropping from a gap of the horizontal chain boiler, carbonized rice hulls are collected by the collector at the bottom of the horizontal chain boiler, and the collected carbonized rice hulls drop on the transverse auger via the outlet at the bottom of the collector, are horizontally conveyed via the transverse auger, are lifted to a position above the coal hopper of the horizontal chain boiler by the longitudinal auger, and finally enter the horizontal chain boiler to be combusted. The rice hull carbonization secondary combustion recycler has the advantages of capabilities of saving fuel, reducing cost and saving labor intensity and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of utilizing biomass energy to generate electricity, and in particular relates to a rice husk carbonization secondary combustion recovery device. Background technique [0002] The use of biomass energy to generate electricity is one of the important ways of biomass utilization. Compared with fossil fuels, biomass has the following advantages: 1), renewability; 2), low pollution: low SOx and NOx emission concentrations; 3), when biomass is used as fuel, during the growth cycle, the impact on the atmosphere The net emission of carbon dioxide is close to zero, which can effectively reduce the greenhouse effect. [0003] At present, there are more than 500,000 industrial boilers in my country, and the annual coal consumption is about 1 / 3 of the total coal consumption in the country. The environmental pollution caused by coal-fired industrial boilers is very serious, and many regions (especially large and medium...

Problems solved by technology

[0005] At present, when using horizontal chain boilers to burn rice husks, due to the gaps in the boiler, some carbonized rice husks will fall from the gaps in the boiler during the combustion process, which will cause waste of fuel and increase costs. Bring environmental pollution and artificial increase
