An apparatus for rice husk carbonization combustion and combustion gas collection-utilization

Abstract

The invention discloses an apparatus for rice husk carbonization combustion and combustion gas collection-utilization. The apparatus comprises a rice husk carbonization combustion device, a cyclone dust removal column and a combustor. The rice husk carbonization combustion device is composed of a feeding open hopper, a combustion cabin and a lower ash bucket. A spraying washing column and a condenser are sequentially arranged between the cyclone dust removal column and the combustor. A blower is arranged at the front end of the combustor. Four observation holes are evenly formed in the periphery of the middle segment of the combustion cabin, so that the rice husk carbonization condition in the combustion cabin can be observed in real time, and the time when ash is discharged can be judged. A cover board of each observation hole is an inverted door installed later. According to the apparatus, unpractical components in gas generated in rice husk smouldering can be effectively removed to obtain a large amount of carbon monoxide and methane gas, and the carbon monoxide and the methane gas are recycled, reused, and used in the combustor. Waste gas can be favorably treated by the apparatus so that the gas is prevented from polluting air and the apparatus has the strong environmental protection significance.

Description

technical field [0001] The invention relates to equipment for carbonized rice husk manufacturing and gas collection and utilization, more specifically, a device for carbonizing rice husk combustion and combustion gas collection and utilization. Background technique [0002] Carbonized rice husk refers to the charcoalized material formed by heating rice husk below its ignition point temperature to make it incompletely burned. It has the characteristics of light weight and low thermal conductivity. Carbonized rice husks can be used as thermal insulation materials for the production of steel and iron in industrial production, and can be used in agriculture to cultivate vegetables, flowers, seedlings, fruit trees and other crops and improve soil. Light a fire, keep warm, etc. It can also be used as a raw material for the production of steelmaking auxiliary materials, and the price in the market varies according to the C content. The incomplete combustion of rice husk is also ...

AI Technical Summary

Problems solved by technology

The incomplete combustion of rice husk is also called "smoldering". The smoke generated during smoldering includes a large amount of carbon monoxide, carbon dioxide, gaseous tar, methane gas and some dust ash obtained from complete combustion. The traditional method is to combine these other simple Discharged after treatment, these gases that can be burned to generate energy are wasted
