Exhaust heat recovery and dust removal integrated type biomass boiler

Abstract

The invention discloses an exhaust heat recovery and dust removal integrated type biomass boiler which comprises a boiler body, a boiler exhaust pipe, a boiler blow-off pipe and a cyclone exhaust heat efficient recoverer, wherein the cyclone exhaust heat efficient recoverer is formed by stacking a tube type heat exchanger and a cyclone dust collector, the boiler exhaust pipe is tangential to the cyclone dust collector, dust is exhausted through a closed-air aspirator at the conic bottom after cyclone de-dusting, the exhaust gas is connected with a conic body through a cyclone rising pipe, penetrates through vertical tubes after scattered uniformly and is exhausted through an exhaust pipe after centralized by an upper hopper; a pure water pool is connected with the lower part of the shell side of the tube type heat exchanger, and the upper part of the shell side of the tube type heat exchanger is connected with the boiler body through a boiler water feed pump. According to the exhaust heat recovery and dust removal integrated type biomass boiler, synchronous processing of exhaust heat use and de-dusting of the biomass boiler is realized, the practicability is high, and the application prospect is wide.

Description

technical field [0001] The invention relates to a biomass boiler, in particular to an integrated biomass boiler with tail heat recovery and dust removal. Background technique [0002] Boilers are thermal and power devices often used in industry. According to the types of combustion materials, they are mainly divided into coal-fired boilers, oil-fired boilers, biomass energy boilers, etc. Among them, biomass boilers mainly use biomass such as straw and firewood as combustion materials. Because biomass such as straw can be regenerated and is rich in resources, it is a vigorously advocated energy source. [0003] However, the existing biomass boilers generally have the defects of insufficient combustion, large smoke and dust, low thermal efficiency, and insufficient utilization of tail heat. These are obviously not in line with the energy-saving and emission-reduction policies vigorously advocated by our country at this stage, and need to be improved. Contents of the inventi...
