Vertical biomass combustion furnace and fruit and vegetable drying machine using same as heat source

Abstract

The invention discloses an efficient, energy-saving and environment-friendly vertical biomass combustion furnace and a fruit and vegetable drying machine using the combustion furnace as a heat source. The vertical biomass particle combustion furnace comprises a storage box, a motor, a feeding device, a combustion chamber, a first combustion furnace, a second combustion furnace, a radiator, a power transmission system, a connecting device, an automatic ignition device, an automatic control system and an oxygen supply device. The combustor is designed to comprise a primary combustion chamber and a secondary combustion chamber and is in a stepped design, and other auxiliary devices such as a coke slag crushing and separating device, an ash and slag discharging device, a slag collector and the like are arranged in the combustion chambers. The combustion furnace has the effects that combustion materials are fully combusted, the combustion utilization rate of biomass combustibles is greatly increased, fuel is saved, waste is reduced, residues generated in the combustion process are removed in time, thus the stability and continuity of fuel combustion are guaranteed, and the normal working state of the drying machine is guaranteed.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable drying, in particular to a vertical biomass combustion furnace and a fruit and vegetable dryer using it as a heat source. Background technique [0002] my country is a big consumer of agricultural products and produces a large amount of agricultural products every year. Drying is one of the most critical links in the use of commodities and deep processing; the efficiency and quality of drying often determine the economic value, food safety and quality of the product to a large extent. [0003] At present, in terms of agricultural product processing and drying, the energy used by existing dryers is mostly coal and fossil fuels, which are non-renewable resources. Using agricultural and forestry waste biomass as drying raw materials can not only use no fossil energy, but also Recyclable and efficient use of agricultural and forestry wastes such as straws has a promising prospect for ener...

AI Technical Summary

Problems solved by technology

[0006] The invention provides a vertical high-efficiency, energy-saving and environment-friendly biomass particle fruit and vegetable dryer and its technology. It innovatively designs two combustion chambers, two combustion furnaces, heat dissipation and coking and slagging devices to solve the problem of insufficient combustion of biomass particles and waste of materials. , the fuel utilization rate is low, and problems such as coking, slagging, nitrogen oxides, and serious emission exceeding the standard are easily generated during the combustion process
