A biomass boiler slag breaking device

Abstract

The invention relates to a biomass boiler slag crushing device. The biomass boiler slag crushing device comprises at least two parallel slag crushing device bodies, and each slag crushing device bodycomprises a cam, a cooling pipe, a tooth part, a water inlet pipe and a water outlet pipe; and for each slag crushing device body, the cam is arranged on the inner wall of a biomass boiler and moves on the horizontal plane, the cooling pipe is horizontally arranged above a chain grate, the two ends of the cooling pipe are connected with the water inlet pipe and the water outlet pipe respectively,the tooth part is arranged on the cooling pipe in a sleeved mode and is inclined upwards, one end of the tooth part abuts against the cam, and the other end of the tooth part abuts against a compression spring fixedly arranged on the inner wall of the biomass boiler, and the tooth part moves in a left and right reciprocated mode in the length direction of the cooling pipe under the action of the cam and the compression spring. According to the biomass boiler slag crushing device, the chain grate drives waste residue to move forward, moreover, the waste residue is lifted through the plurality of slag crushing device bodies which are arranged front and back, and the tooth part is driven to move left and right on the cooling pipe under the action of the cam and the compression spring so thattransverse clamping force generated by stagger of the front tooth part and the rear tooth part can be applied to the waste residue, and therefore the crushing strength is increased.

Description

technical field [0001] The invention relates to the technical field of biomass boilers, in particular to a biomass boiler slag breaking device. Background technique [0002] Biomass pellet fuel is efficient, clean, easy to ignite, CO 2 With the advantages of nearly zero emission, it can replace fossil fuels such as coal and be used in civil fields such as cooking and heating, as well as industrial fields such as boiler combustion and power generation. The density of biomass pellet fuel is 1.0~1.4t / m 3 , the energy density is equivalent to medium bituminous coal, the firepower is long-lasting when used, and the furnace temperature is high. It is a good alternative fuel for coal at present. The biomass pellet fuel is cylindrical or block-shaped, consistent in shape, has good fluidity, and is easy to realize combustion equipment. Automatic control and automatic combustion. [0003] In countries such as Europe and the United States, biomass pellet fuels and supporting high-ef...

AI Technical Summary

Problems solved by technology

[0003] In countries such as Europe and the United States, biomass pellet fuels and supporting high-efficiency combustion equipment have become very popular, but these biomass pellet fuels are mainly wood pellet fuels, which have the advantages of high calorific value, low ash content, and are not easy to slagging after combustion. The biomass briquette fuel is mainly crop straw. Compared with wood pellet fuel, there are great differences in physical properties and chemical components, resulting in differences in combustion characteristics. Straw pellet fuel has high ash content, low ash melting point, The alkali metal content is high, and problems such as slagging and serious ash accumulation in the equipment are prone to occur during the combustion process
