Technical Field

[0001] This invention relates to the field of biomass gas boiler technology, specifically an environmentally friendly and energy-saving water-tube biomass gas boiler. Background Technology

[0002] Biomass gas boilers are environmentally friendly thermal energy equipment that uses biomass gas as fuel to convert chemical energy into thermal energy to produce hot water and steam. They are a subcategory of biomass boilers and are designed to use the combustible gas produced after biomass gasification as an energy source.

[0003] The existing biomass gas boilers have a fixed internal material loading mechanism. The input and output of materials must be transferred after the boiler is shut down and cooled. This process consumes a lot of energy, which not only increases energy consumption but also affects the efficiency of agricultural waste incineration and conversion into biomass gas. Furthermore, the fixed heating surface accumulates ash over a long period of time, which reduces the efficiency of agricultural waste incineration and leads to the drawback of incomplete conversion of agricultural waste into biomass gas.

[0028] Preferably, the protective plate 1101 has a triangular cross-section, and the two symmetrically distributed protective plates 1101 are used to provide limit protection for the longitudinal lifting of the wind hood furnace box 170 and the sealing cover 1701. Both ends of the hood furnace box 170 are provided with protruding threaded rod sections, and the pressure pad 1703 is fixed to the protruding threaded rod section at one end of the hood furnace box 170 by multiple nuts.

A gear is fixedly installed on the pipe section of the rotating wheel 310 that extends to the outside of the rear sealing plate 140, and the gear meshes with the deflection gear 1602. When the motor 1601 starts and drives the deflection gear 1602 to rotate, the gear and wheel 310 that are assisted in rotating will drive multiple sets of storage hoods 330 and collection mesh pads 340 to rotate at a constant speed. This facilitates the rapid replacement of multiple sets of storage hoods 330 and collection mesh pads 340 for quick loading and unloading of materials, further improving the efficiency of biomass gas generation and achieving the goal of energy saving. Among them, the stabilizing outer plate 1705, together with the anti-overflow plate 320, is used to adapt and seal the ports at both ends of the material storage hood 330 and the material collection mesh pad 340, which facilitates the safety of agricultural waste during incineration and improves the efficiency of biomass gas transfer. In addition, the inner cavity of the storage hood 330 has a fan-shaped structure, which, together with the unloading tray 350, can achieve effective separation of biomass gas and agricultural waste. Example 2:

[0031] Combination Figures 6 to 10As shown, in the above embodiment, the biomass gas transfer mechanism 200 includes a hollow gas cylinder 210 that extends through the middle of the inner cavity of the heat insulation shell 110. A front plug 220 is installed at one end of the hollow gas cylinder 210, and a rear plug 230 is installed at the other end of the hollow gas cylinder 210. An external gas pipe 240 is movably installed in the pipe section outside the front plug 220, and two inserts 2201 are inserted into the pipe section outside the front plug 220. The two inserts 2201 are used to limit and clamp the external gas pipe 240. Two mounting pads 260 are installed in the inward V-groove at the bottom of the hollow air cylinder 210. Two reinforcing pads 250 are symmetrically distributed at both ends of the two mounting pads 260. A support plate 2501 is fixedly installed on the inner wall of the reinforcing pad 250. A spring 2502 is fixedly installed at the bottom of the support plate 2501. A U-shaped shell 2703 is fixedly installed at the bottom of the spring 2502. A horizontally placed rectangular plug plate 2701 is inserted into the inside of the U-shaped shell 2703. Two reinforcing pads 250 are fixedly installed with horizontal beams 270, and rectangular plugs 2701 are movably installed in the slots inside the beams 270. A lifting frame 2702 is fixedly installed on the rod section through which the rectangular plugs 2701 extends to the outside of the U-shaped shell 2703. The internal slots of the beam plate 270 have a T-shaped structure, and the cross-section of the rectangular plug plate 2701 has an inverted triangular structure, which facilitates the directional and safe transfer of biomass gas.

[0032] Preferably, the inner walls at both ends of the hollow air cylinder 210 are provided with columns, and the front plug 220 and the rear plug 230 are fixedly installed on the corresponding columns by multiple bolts. The front plug 220 is fixed in the front sealing plate 120 by the first fixing plate 1203, and the rear plug 230 is fixed in the rear sealing plate 140 by the second fixing plate 1402, so as to ensure the stability of the multiple sets of material storage hoods 330 and material collection mesh pads 340 rotating around the hollow air cylinder 210 as the axis. Two reinforcing pads 250 are respectively snapped into the fan-shaped slots at the bottom of the front plug 220 and the rear plug 230. The beam plate 270 is installed in the middle of the raised plate section at the bottom of the two mounting pads 260. When the overflow plate 320 is rotated to the bottom, the arc-shaped port at its top will push the rectangular plug plate 2701 upward by squeezing it upward against the lifting frame 2702. At this time, the internal slot of the beam plate 270 will be exposed, and the biomass gas transferred upward from the inclined hole 3501 can be input into the inner cavity of the hollow gas cylinder 210 through the gap between the beam plate 270 and the rectangular plug plate 2701. Finally, the biomass gas can be released outward through the inner cavity of the hollow gas cylinder 210 and the external gas pipe 240. Example 3:

[0033] Combination Figure 11 and Figure 12As shown, in the above embodiment, the overflow plate 320 has a rectangular hole 3201 inside, and the wheel 310 has a shaft 3202 inserted inside. The shaft 3202 is movably installed on the outside of the door panel 3203, and the rectangular hole 3201 is fixedly installed on the bracket 3701. The bracket 3701 consists of an elliptical pad and two vertical rods. Compression springs 3702 are provided on the outside of the two vertical rods, and leaf springs 370 are movably installed on the two vertical rods. The bottom end of the leaf springs 370 is fixedly installed on the door panel 3203. An insulating shell 360 is fixedly installed inside the rectangular hole 3201. An electromagnet 3601 is fixedly installed inside the insulating shell 360, and a coil 3602 is wound on the electromagnet 3601. A magnetic push rod 3603 is movably installed inside the insulating shell 360, and the outer end of the magnetic push rod 3603 is fixedly installed on the leaf spring 370.

[0034] Preferably, the coil 3602 is connected to an external power source via a wire, and the coil 3602 is energized and de-energized via a client. At this time, the magnetic field of the electromagnet 3601 on the magnetic push rod 3603 will change. Correspondingly, the leaf spring 370 is pulled and, together with the two compression springs 3702, can control the door panel 3203 to quickly tilt to the side, which facilitates the input and output of waste material in the uppermost set of storage hoods 330 and collection mesh pads 340. The input and output waste material can be effectively separated by the unloading tray plate 350. The inner port of the rectangular hole 3201 is provided with two rectangular baffles to facilitate the calibration support of the door panel 3203 after reset.

[0035] The working principle and usage process of the present invention: The device is placed on the ground beforehand until the feed inlet of the feed hopper 1201 is vertically upward. According to the usage requirements, a visual monitoring system can be added to the inner cavity of the heat-insulating shell 110 with a sealed structure to monitor the alignment status of the bottom set of material storage covers 330 and material collection net pads 340 with the top of the sealing cover 1701 in real time. When the lowest collecting mesh pad 340 is directly above the sealing cover 1701, the hydraulic component 1301 is operated by the client until the hydraulic rod inside the hydraulic component 1301 retracts and drives the horizontal guide rod 1702 and the sealing cover 1701 to rise smoothly. Finally, the top of the sealing cover 1701 will quickly adhere to the lower surface of the collecting mesh pad 340. The agricultural waste transferred by the external conveying system will move from the feed hopper 1201 to the inner cavity of the uppermost set of storage covers 330 and collecting mesh pad 340. The transferred agricultural waste can enter the high area of ​​the bottom port of the feed hopper 1201 along the uppermost discharge tray 350. Finally, the agricultural waste will move along the upward slope of the discharge tray 350 towards the center of the storage cover 330 and collecting mesh pad 340. At the same time, the motor 1601 started by the client will drive the deflection gear 1602 to rotate. The rotating deflection gear 1602 will help the gear of the wheel 310 to pass through the external pipe section of the rear sealing plate 140. As the wheel 310 rotates, the multiple anti-overflow plates 320 fixed to the inside of the wheel 310 by multiple reinforcing pins 3101 will drive multiple sets of storage hoods 330 and collection mesh pads 340 to rotate at a uniform speed. The agricultural waste transported in an orderly manner through the feed hopper 1201 can quickly and conveniently fill the multiple sets of storage hoods 330 and collection mesh pads 340. After the set of storage hoods 330 and collecting mesh pads 340 filled with agricultural waste rotates circumferentially and moves to the bottom, the bottommost set of storage hoods 330 and collecting mesh pads 340 can flip and carry the agricultural waste guided by the inclined surface of the unloading tray 350. After the flame is sprayed upward through the inner cavity of the hood furnace box 170, the agricultural waste carried by the bottommost collecting mesh pad 340 can be fully and efficiently incinerated. The gas generated during incineration will be transferred along the inclined holes 3501 to the upper half of the cavity of the storage hood 330, while the overflow plate 320 faces... After the arc-shaped plate segment of the hollow air cylinder 210 rotates in an orderly manner to the bottom of the reinforcing pad 250, the lifting frame 2702 will be pressurized upward by the arc-shaped port at the top of the anti-overflow plate 320. The rising lifting frame 2702 will drive the rectangular plug plate 2701 to be lifted upward from the inner cavity of the beam plate 270. Finally, the gas entering the upper half cavity of the storage hood 330 can be transferred from the exposed gap between the beam plate 270 and the rectangular plug plate 2701 to the interior of the hollow air cylinder 210. The gas entering the interior of the hollow air cylinder 210 can be output outward from the front plug 220 and the external air pipe 240. After the waste in the bottom set of storage hoods 330 and collection mesh pads 340 has been incinerated, the rotating multi-set biomass gas transfer mechanism 200 can transfer the incinerated waste upwards until the incinerated waste is rotated to the top. The energized coil 3602 will change the magnetic field of the electromagnet 3601, and the attracted magnetic push rod 3603 will drive the leaf spring 370 to contract, which will then drive the door panel 3203 to flip outwards around the shaft 3202. Finally, after the incinerated waste flips to the inclined surface of the discharge tray 350, it can be transferred from the rectangular hole 3201 and the flipped door panel 3203 into the discharge hopper 1401. Meanwhile, the agricultural waste input into the feed hopper 1201 via the external conveying system can be input simultaneously.
