Rotary type water-cooled fire grate

Abstract

The invention discloses a rotary type water-cooled fire grate, which comprises a drive device, an installation frame, a plurality of large rotary discharge pipes and small fixed tier poles, wherein the large rotary discharge pipes are arranged on the installation frame in parallel at intervals; one small fixed tier pole is arranged between each two adjacent large rotary discharge pipes; the drive device is connected with all the large rotary discharge pipes through transmission components. The rotary type water-cooled fire grate is ingenious and reasonable in structural design; the large rotary discharge pipes are arranged in parallel at intervals, and one small fixed tier pole capable of forming a certain barrier is arranged between each two adjacent large rotary discharge pipes, so that air leakage can be prevented, fuel can be fully combusted, meanwhile, wind energy can be utilized maximally, the large rotary discharge pipes are linked synchronously, the deslagging effect is good, and the application range is wide; in addition, water cooling is adopted for protection, the service life is long, and the rotary speed and the working time of a motor can be controlled through a controller, so that the rotary type water-cooled fire grate can meet the work requirements under different conditions, is simple, easy and convenient to operate, is high in degree of automation, and is beneficial to be popularized and applied widely.

Description

technical field [0001] The invention relates to the technical field of gasification furnaces, in particular to a rotary water-cooled fire grate used in gasification furnaces. Background technique [0002] Biomass energy has the characteristics of wide distribution, renewable and environmental friendliness. The development and utilization of renewable resources is a main direction for my country to achieve sustainable development. Currently, biomass conversion technologies are mainly divided into biomass gasification, liquefaction, solidification and direct combustion technologies. Biomass energy gasification technology is one of the important methods. Realize the in-depth utilization of low-grade biomass energy by means of gasification, reduce the supply of fossil fuels and the serious pollution to the environment caused by direct burning of fossil fuels, and have a great impact on improving rural living standards, improving the ecological environment, and ensuring national...

AI Technical Summary

Problems solved by technology

Due to the large gap between the two fire grates and between the fire grate and the furnace wall, there is too much air leakage, resulting in insufficient combustion of fuel during the combustion process and a large waste of wind energy

If the average gap is too small, the large slag cannot be discharged smoothly, and the scope of application is narrow
