A biomass gasification furnace grate ash device

Abstract

The invention discloses a biomass gasification grate ash device, comprising a grate, the upper end of the grate is connected with the ash outlet at the bottom end of the gasification furnace, the lower end of the grate is connected with the ash hopper, the lower end of the ash hopper is fixed with a sealed water tank and Connected, the sealed water tank is filled with condensate, the side of the sealed water tank is equipped with a slag collection box, and the slag collection box is equipped with a U-shaped liquid-sealed pipe, and the end of the U-shaped liquid-sealed pipe near the sealed water tank is connected to the sealed water tank. There is a slag pushing mechanism located at the liquid level of the condensate. The slag pushing mechanism is used to push the ash floating on the liquid surface of the condensate into the U-shaped liquid seal tube. It is used to remove the ash and slag in the U-shaped liquid seal pipe to the slag collection box. The biomass gasification furnace grate ash device can remove the ash on the surface of the condensate in time to prevent the ash hopper from being blocked by the ash.

Description

technical field [0001] The invention relates to a gasification furnace grate ash device, in particular to a biomass gasification furnace grate ash device. Background technique [0002] The straw gas produced by the biomass gas furnace belongs to green new energy and has strong vitality. Since the raw materials of plant gas are crop straw, forest waste, edible fungus residue, cattle, sheep and livestock dung and all combustible substances, it is an inexhaustible renewable resource. Each farmer only needs 3-5 kilograms of plant raw materials per day to solve the daily life energy (cooking, heating, showering), and burn like liquefied petroleum gas, which can completely change the smoky life style in rural areas of our country. Traditional firewood stoves can be banned and liquefied petroleum gas can be replaced. [0003] Biomass gasifiers are mainly divided into updraft fixed bed gasifiers, downdraft fixed bed gasifiers and fluidized bed biomass gasifiers. Downdraft biomass ...

AI Technical Summary

Problems solved by technology

Due to the high temperature of the ash coming out of the gasifier, in the process of contacting with the water in the water tank, the ash at high temperature encounters cold water, rapidly cools down and produces a large amount of water vapor, and the phenomenon of water shock occurs , and the outer surface of the ash that falls directly into the water is wrapped with tar. After the ash wrapped with tar falls into cold water, it will directly float on the water surface and cannot sink, causing a large amount of ash to accumulate and cannot be discharged from the ash hopper until it is blocked. The ash outlet makes it unable to work normally, so the slagging device of the existing fixed bed gasifier needs further improvement
