Fuel gas rotary furnace bio-organic matter heat treatment device

Abstract

The invention relates to a fuel gas rotary furnace bio-organic matter heat treatment device. The fuel gas rotary furnace bio-organic matter heat treatment device comprises a burning furnace, a reactor, a pyrolysis gas re-burning device and a base. The burning furnace and the reactor are placed on the base provided whit universal wheels, so that moving of the heating furnace is convenient. The fuelgas rotary furnace bio-organic matter heat treatment device is provided with an air cooler, pyrolysis gas generated by the reactor is subjected to air cooling, water cooling and water sealing in sequence and then returns to the bottom of the burning furnace to burn under burning supporting of burning-supporting agents, and the condensing load is effectively reduced through the air cooler. The burning furnace conducts heating in a fuel gas burning mode. A cooking range is arranged, a pyrolysis gas returning pipe is arranged in the middle of the cooking range, and thus the pyrolysis gas and burning-supporting gas burn jointly.

Description

technical field [0001] The invention relates to a bio-organic matter heat treatment device of a gas-fired rotary furnace, which belongs to the field of thermochemical conversion of biomass. Background technique [0002] Biomass energy is the fourth largest energy source in the world after petroleum, coal, natural gas and other fossil energy sources. my country is rich in biomass energy. The annual production of biomass such as crop straws and grain husks has a considerable amount after deducting various used parts. The biomass of 200-250 million tons of standard coal remains to be developed, and the waste biomass resources in forestry are about 37 million cubic meters per year, equivalent to 20 million tons of standard coal. In addition, my country still has urban organic waste biomass resources equivalent to 200 million tons of standard coal to be processed and developed. There are many ways to utilize biomass energy, among which, in the thermochemical conversion technology...

Problems solved by technology

In the entrained bed reactor, air and propane are introduced into the lower part of the reaction tube according to the stoichiometric ratio for combustion. The hot flue gas passes through the reaction tube from bottom to top and mixes with the bio-organic matter added thereafter to heat the bio-organic matter. Generally, the hot flue gas The gas flow rate should be 4 times that of the biological flow rate. The disadvantages are: a large amount of hot flue gas is required as a carrier gas during operation, and the calorific value of non-condensable gas is low; Requires carrier gas, but high energy consumption for the whole setup
