Embodiment Construction

[0044] It should be understood that in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0045] see figure 1 , the present invention provides a biomass fuel hot air equipment that can cool down, which includes a furnace body 1, an inner tank 2, a combustion bin 3, a fuel bin 4, an oxygen supply 5, a blower 6, an air heating unit 7, and at least two groups Lifting mechanism and heating control unit. In this embodiment, there are two sets of lifting mechanisms (81 and 82), and each set of lifting mechanisms may include one or more lifting mechanisms.

[0046] The furnace body 1 is provided with a cold air inlet 11 , a hot air outlet 12 , a material inlet 13 and an oxygen inlet 14 ; the hot air outlet 12 is provided with a temperature sensor 9 .

[0047] The inner tank 2 is arranged in the furnace body 1, and the space between its outer wall and the inner wall of the furnace body 1 forms a heating chamber A; the top of the in...

Abstract

The invention relates to a biomass fuel blast heater with a cooling function. An air heating unit is modified so that air can be gradually heated by multiple heating spaces, biomass fuel combustion heat can be better absorbed, and the effective utilization rate of heat energy generated by combustion of biomass fuel is increased. By modifying the structure of a flame bridge and additionally arranging a cooling unit, two sets of lifting mechanisms, a temperature sensor and a trigger module, working states of the lifting mechanisms and an oxygen inlet valve are controlled by utilizing external trigger signals and detection signals input by the temperature sensor, namely, the lifting mechanisms are used for controlling the fuel combustion total amount and height, so that combustion flames of part of or all of fuel are close to or away from the air heating unit. The oxygen inlet valve is controlled to achieve oxygen supply control over combustion, and thus the air outlet temperature is regulated and controlled. The cooling function is further achieved, the using requirements are better met, and air can be heated to the same temperature with less biomass fuel.

Description

technical field [0001] The invention relates to a hot blast stove, in particular to a cooling biomass fuel hot blast device. Background technique [0002] Hot air stove is a kind of chemical energy or electric energy of conventional energy is converted into thermal energy, so that the energy is supplied to the corresponding equipment in the form of hot air, often used in dryers, dryers, molding machines and heating. [0003] Biomass fuel refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry wastes (such as straw, sawdust, bagasse, rice bran, etc.), and when biomass fuel is used as fuel, agricultural and forestry wastes need to be used as raw materials, and after It is a new type of clean fuel that can be directly burned in various shapes (such as lumps, granules, etc.) through crushing, mixing, extrusion and drying. [0004] Therefore, for the sustainable development of society, biomass fuels have been widely used as fuels for hot bl...
