Biomass steam generator

Abstract

The invention discloses a biomass steam generator, and relates to the field of boilers. The biomass steam generator comprises a rack, a furnace body of a biomass combustion chamber arranged in the rack, a boiler body heated on the furnace body and a steam chamber, wherein the steam chamber is positioned at the top end of the boiler body and communicates with the boiler body; a feeding port and a smoke discharging pipe further communicate with the furnace body and are arranged on the furnace body; a dust removing and filtering device is arranged on the side wall of the rack, and the dust removing and filtering device comprises a filtering box fixedly connected to the rack and a water spraying assembly arranged in the filtering box; the water spraying assembly communicates with a water source through a water inlet pipe; the smoke discharging pipe communicates with the position, close to the bottom, of the filtering box; a water storage box is arranged below the filtering box; the bottomof the filtering box is connected with a water discharging pipe for discharging water to the water storage box; and an air outlet pipe is arranged at the top of the filtering box. Through the arrangement of the dust removing and filtering device, the situation that dust enters the outside air is reduced through the water spraying assembly, so that the influence of the dust in the smoke on the environment is reduced.

Description

technical field [0001] The invention relates to the field of boilers, more specifically, it relates to a biomass steam generator. Background technique [0002] Biomass fuels are mostly rice husks, peanut husks, corncobs, camellia husks, cottonseed husks and block-shaped environmentally friendly new energy produced by processing the "three leftovers". A biomass steam generator is a mechanical device that heats water into hot water or steam by burning biomass fuel to form heat energy. [0003] The existing biomass steam generator includes a frame, a furnace body of a biomass combustion chamber arranged in the frame, a pot body heated on the furnace body, and a steam chamber located at the top of the pot body and communicated with the pot body. The furnace body is also connected with a feed port and a smoke exhaust pipe. When the biomass fuel is burned, the combustion flue gas is exhausted through the smoke exhaust pipe. [0004] However, when the above-mentioned biomass stea...

AI Technical Summary

Problems solved by technology

[0004] However, when the above-mentioned biomass steam generator is used, dust will be generated after the biomass fuel is burned, and the dust will easily follow the flue gas and be discharged into the outside air through the smoke exhaust pipe, causing environmental pollution, which is troublesome and needs to be improved
