Gasifier stirring and pushing adjustment and composite gas-taking method and device

Abstract

The invention relates to a gasifier stirring and pushing adjustment and composite gas-taking method and a gasifier stirring and pushing adjustment and composite gas-taking device, and aims to solve the problems that gas is generated unstably and is easy to burn partially and burn in a mixed way, the burning state is difficult to adjust, the mixture of tar, water and dust cannot be treated in a centralized way, materials have low adaptability and low continuity, the gas and the tar at the outlet cannot be completely burnt, pots, kettles and the environment can be polluted, and the like in the conventional gasifier. Combustible gas is obtained in two ways. A composite stirring and pushing gasifier consists of a fuel generating and adjusting device, a water tank, tar, dust and water purifying and centralizing device and a gas combustion and conversion device. By the method and the device, the problem of partial burn is solved, the continuous workability of the gasifier is guaranteed, full oxidation and material discharge are facilitated, gas temperature is reduced and afterheat is fully utilized. A fuel conveniently and reliably flows; combustion is stable; harmful gases such as the tar and the like are not discharged; and a furnace end is not blocked.

Description

technical field [0001] The invention relates to a recycling treatment device for biomass waste, in particular to a gasification furnace stirring adjustment and compound gas extraction method and its device. Background technique [0002] Existing gasification furnaces have various forms, mainly burning various combustible plant stems, shells, tree blocks, etc. in a closed gasification furnace body under an oxygen-deficient state. During the burning process, the plants will release combustible gas. By purifying the combustible gas and introducing it into the stove to ignite, it can be used as combustible energy for units or households like natural gas, such as for lighting fires, cooking, and boiling water. and other affairs. The fixed bed gasifier gas extraction technology generally has the following methods in terms of technical principles: [0003] 1. Upflow type (upward suction type), its working form is that the gasification agent (gas) flows from bottom to top in the f...

AI Technical Summary

Problems solved by technology

[0012] In order to solve the problem of unstable gas production in existing fixed-bed gasifiers, partial combustion and cross-combustion, difficulty in adjusting the combustion state, difficulty in the flow of materials in the furnace, and the inability to adjust the combustion state in a fully sealed state, and the centralized treatment of tar and water , dust mixture, material adaptability is not high, the continuity of combustion cannot be guaranteed, and the export gas tar is not completely burned, polluting the pot and the environment, etc.
