[0002] With the acceleration of global industrialization, the demand for energy in industrial production continues to surge, while people's awareness of environmental protection is also deepening. Under such a background, the traditional industrial steam supply mode mainly based on fossil energy not only faces the severe challenge of energy depletion, but also causes serious damage to the environment due to the emission of a large amount of pollutants in the combustion process.

[0003] Biomass energy, as a kind of energy with abundant reserves, renewable and clean, has gradually become a key breakthrough to solve the current energy and environmental problems. Biomass raw materials have the characteristics of extremely wide sources, such as agricultural waste (straw, rice husk, etc.), forestry residues (sawdust, branches, etc.), and various types of organic household waste, etc., and the cost is relatively low. Reasonable treatment and conversion of biomass raw materials into steam for industrial supply can not only greatly alleviate the pressure on industrial development caused by energy shortage and reduce the high dependence of industrial production on traditional fossil energy, but also significantly reduce the emission of greenhouse gases, sulfides, nitrogen oxides and other pollutants generated by the combustion of fossil energy, and effectively promote the development of industrial production towards a green and sustainable direction.

[0004] At the same time, in the gasification process of biomass raw materials, the internal structure of the traditional gasification furnace is not reasonable, and in the existing gasification furnace, the raw materials are mostly added to the gasification furnace at one time, which causes the raw materials to accumulate in the gasification furnace, and the raw materials accumulated in the internal structure cannot be quickly combusted, resulting in insufficient combustion of raw materials in the furnace, low energy utilization efficiency, and increased production cost.

[0018] 2. Compared with the prior art, the biomass raw material processing system of the present invention is equipped with a multi-stage combustion assembly in the gasifier. By setting multiple combustion platforms on the inner walls of the front and rear sides of the gasifier, the raw material will be stacked on multiple combustion platforms in sequence after entering the gasifier for combustion.

After the driving motor 26 is started, the short rod 32 is driven to rotate, the incomplete gear 29 on the short rod 32 is intermittently engaged with the second gear 28 on the second rotating shaft 30, and the torsional spring elastically connected between the second rotating shaft 30 and the fixed plate is matched, so that the second rotating shaft 30 swings back and forth. That is, when the second gear 28 is engaged with the incomplete gear 29, the rotating plate 40 is upwardly rotated, and the torsional spring is compressed. When the second gear 28 is not engaged with the incomplete gear 29, the rotating plate 40 is rotated back under the action of the torsional spring, thereby driving the cross rod 44 and the rotating plate 40 to swing, avoiding the raw materials from being accumulated on the rotating plate 40 and unable to slide, and making the raw materials more evenly laid on the combustion platform 34, which is beneficial to improve the combustion efficiency.

In the initial state, the second electromagnet 49 is de-energized, the rectangular block 51 on the right side is located in the rectangular groove 47, and the rectangular block 51 on the left side is not located in the rectangular groove 47, when the electric rod 19 is contracted to make the conductive rod 25 contact with the conductive block 24, the loop is conducted, the second electromagnet 49 is energized, and an attractive force is generated on the rectangular block 51, so that the two rectangular blocks 51 are moved, and the connection and separation control of the horizontal rod 44, the first rotating shaft 22 and the second rotating shaft 30 are realized. Through the power supply and the control switch in the control box, the operation of each component in the whole system can be controlled, and the normal work of the biomass raw material processing system is ensured.

[0040] The present application can be described as follows: the gas generated after the biomass raw material is reacted in the gasifier 2 first enters the top space of the steam boiler 5 which is communicated with the gasifier 2 through the first pipeline 4, at this time, the gas generated by gasification heats the water in the boiler 5, thereby generating steam for industrial production, under the action of the air blower 7, the gas in the steam boiler 5 enters the top space of the denitration reactor 9 through the second pipeline 6. In the denitration reactor 9, the nitrogen oxides and other pollutants in the gas are removed and treated. The treated gas enters the top space of the economizer 11 from the bottom space of the denitration reactor 9 through the third pipeline 10, and the economizer 11 recovers the heat in the gas to reduce the temperature of the gas. Then, the gas enters the gas inlet end of the induced draft fan 14 from the bottom space of the economizer 11 through the fourth pipeline 13, and the induced draft fan 14 provides power to deliver the gas to the bottom space of the spray tower 15. In the spray tower 15, the gas is further purified by spraying to remove some impurities and pollutants. Finally, the gas treated by the spray tower 15 enters the bottom space of the wet electrostatic precipitator 16 from the top space, and the wet electrostatic precipitator 16 removes the remaining fine particulate matter and other pollutants in the gas by electric field action, so that the treated gas meets the environmental protection emission standard and is discharged.

[0041] The biomass raw material is inclinedly conveyed to the feed inlet 17 at the upper end of the gasifier 2 by the feeding conveyor 1 and enters the gasifier 2, in the initial state, the plurality of first electromagnets 41 are in the state of being powered off, and the plurality of rotating plates 40 are in the vertical state. When the raw material is added, the raw material will first fall on the two combustion platforms 34 located above through the V-shaped plate 33. When the raw material on the combustion platform 34 reaches a certain weight, the pressure rod 39 presses the pressure sensor 38, at this time, the pressure sensor 38 generates an electric signal which is transmitted to the control box, and the control box controls the corresponding pneumatic rod 19 to retract. Since the second electromagnet 49 is in the state of being powered off in the initial state, the right rectangular block 51 is located in the rectangular groove 47, and the left rectangular block 51 is not located in the rectangular groove 47.

[0042] The retraction of the pneumatic rod 19 drives the moving block 20 and the rack 21 to move backward, the first gear 23 drives the cross rod 44 to rotate, so that the rotating plate 40 rotates to the inclined state. When the conductive rod 25 contacts the conductive block 24 due to the retraction of the pneumatic rod 19, the first electromagnet 41 and the second electromagnet 49 are powered on. After the first electromagnet 41 is powered on, the repulsive force is generated on the telescopic plate 43, so that the telescopic plate 43 extends out of the moving groove. The subsequent raw material will fall on the next combustion platform 34, and in this way, a certain weight of raw material is placed on each combustion platform 34;

[0043] The second electromagnet 49 is powered to generate an attractive force on the rectangular block 51, so that the two rectangular blocks 51 move to the right, at this time, the left rectangular block 51 enters the rectangular groove 47, and the right rectangular block 51 moves away from the corresponding rectangular groove 47 (when the left rectangular block 51 enters the rectangular groove 47, at this time, the right rectangular block 51 is just moved out of the corresponding rectangular groove 47), during the operation of the driving motor 26, the intermittent meshing of the incomplete gear 29 and the second gear 28, and the cooperation of the torsional spring, make the rotating plate 40 swing continuously, so that the raw materials are as evenly laid as possible on the combustion platform 34, and at the same time, it is ensured that the raw materials cannot slide off the rotating plate 40.

[0044] Since the combustion platform 34 is net-shaped, during each combustion, the ash and slag will fall on the inclined plate 35, then fall on the bottom of the gasification furnace 2 through the middle area of the gasification furnace 2, and finally be discharged through the slag discharge pipe.

[0045] With the combustion of the raw materials on the combustion platform 34, the weight on the combustion platform 34 is continuously reduced, when the raw materials on the combustion platform 34 are completely combusted, the pressure sensor 38 will again transmit a signal to the control box, the control box controls the corresponding pneumatic rod 19 to stretch, the moving block 20 drives the rack 21 to reset, after the moving block 20 moves, the conductive block 24 and the conductive rod 25 are separated, at this time, the first electromagnet 41 and the second electromagnet 49 are powered off, under the elastic action of the second spring 42 and the third spring 50, the telescopic plate 43 resets, at the same time, the two rectangular blocks 51 reset, the cross rod 44 is connected with the first rotating shaft 22 again, with the continuous stretching of the pneumatic rod 19, the cross rod 44 is driven to rotate in the opposite direction through the first rotating shaft 22, the rotating plate 40 resets, so that the subsequent raw materials can fall on the combustion platform 34 again.

[0046] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
