Description

Technical Field

[0001] The utility model relates to the technical field of gasifiers, in particular to a biomass fuel combustion gasification device. Background Art

[0002] The biomass fuel gasification furnace mainly converts the biomass fuel from solid to gas through the reaction of biomass fuel and gasifying agent, releases heat, and then transports the gas to the gas stove through a pipeline, thus completing the entire combustion process.

[0003] Under the existing technology, when using a biomass fuel gasifier, it is only necessary to add biomass fuel into the gasifier, decompose the biomass material into combustible gas through combustion and heating, and then burn the combustible gas to generate heat energy. When adding biomass fuel, it is inevitable that some gas will be discharged. At the same time, some dust will overflow when the gas is discharged, which will have a certain impact on the subsequent combustion.

[0004] Therefore, we proposed a biomass fuel combustion gasification device that can achieve closed loading during operation and well treat the output gas to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a biomass fuel combustion gasification device to solve the problems raised in the above background technology.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A biomass fuel combustion gasification device comprises a gasifier, wherein a hopper is fixedly connected to the top of the gasifier, a feed pipe is fixedly connected to one side of the top of the hopper, a fixed plate is fixedly connected to the bottom end inside the hopper, a conical cylinder is rotatably connected to the top of the fixed plate, and grooves are symmetrically provided on the tops of the conical cylinder and the fixed plate, an air guide pipe is fixedly connected through one side of the gasifier, a filter box is fixedly connected to the bottom end of the air guide pipe, a fixed disk is fixedly connected to the upper end inside the filter box, and a filter bag is fixedly connected to the bottom end of the fixed disk.

[0008] As a further solution of the utility model: a closing valve is provided on one side of the feed pipe.

[0009] As a further solution of the utility model: a driving motor is fixedly connected to the top of the hopper, and an output end of the driving motor is fixedly connected to the conical barrel through a rotating rod.

[0010] As a further solution of the utility model: the arc length of the notch is less than one quarter of the circumference of the conical tube and the fixed plate, and the notches on the conical tube and the fixed plate are the same in size.

[0011] As a further solution of the utility model: a servo motor is fixedly connected to the bottom end of the filter box, and a scraper is fixedly connected to the output end of the servo motor.

[0012] As a further solution of the utility model: a collecting box is fixedly connected to the bottom end of the filter box, and the top end of the collecting box extends through and into the interior of the filter box.

[0013] As a further solution of the utility model: ventilation holes are evenly opened on the top of the fixed disk outside the filter bag, and an air outlet pipe that penetrates the filter box is fixedly connected to the middle position of the top of the fixed disk.

[0014] Beneficial effects of the utility model:

[0015] 1. A biomass fuel combustion gasification device in the utility model adds biomass fuel through a feed pipe, then closes the valve, and drives the motor to make the conical cylinder and the notch on the fixed plate overlap. At this time, the biomass fuel can be added to the gasifier through the notch. During this process, it always remains closed from the outside, which effectively avoids gas leakage.

[0016] 2. The biomass gasification gas produced by the biomass fuel combustion gasification device in the utility model acts on the filter bag through the air guide pipe and the air vent, and is discharged from the air outlet pipe after filtering. In this process, impurities such as dust are well avoided from being brought out. Subsequently, the surface of the filter bag can be cleaned only by driving the scraper to rotate forward and reverse periodically through the servo motor, thereby ensuring normal filtering efficiency and facilitating the collection of impurities such as dust inside the collection box.

DETAILED DESCRIPTION

[0024] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 5 In this embodiment, a biomass fuel combustion gasification device includes a gasifier 1, a hopper 2 is fixedly connected to the top of the gasifier 1, a feed pipe 4 is fixedly connected to one side of the top of the hopper 2, a fixed plate 11 is fixedly connected to the bottom end of the hopper 2, a conical cylinder 10 is rotatably connected to the top of the fixed plate 11, and the conical cylinder 10 and the top of the fixed plate 11 are symmetrically provided with notches 13, an air guide pipe 5 is fixedly connected to one side of the gasifier 1, a filter box 7 is fixedly connected to the bottom end of the air guide pipe 5, a fixed disk 15 is fixedly connected to the upper end of the filter box 7, and a filter bag 12 is fixedly connected to the bottom end of the fixed disk 15.

[0026] like Figure 1 and Figure 2 In this embodiment, a closing valve is provided on one side of the feed pipe 4 to facilitate closing treatment after feeding.

[0027] like Figure 1 and Figure 2 In this embodiment, the top of the hopper 2 is fixedly connected with a driving motor 3, and the output end of the driving motor 3 is fixedly connected to the conical cylinder 10 through a rotating rod, so that the driving motor 3 drives the conical cylinder 10 to rotate.

[0028] like Figure 3 In this embodiment, the arc length of the notch 13 is less than one quarter of the circumference of the conical tube 10 and the fixed plate 11, so that when the notch 13 is not aligned, the conical tube 10 and the fixed plate 11 can be closed, and the notch 13 on the conical tube 10 and the fixed plate 11 are the same size.

[0029] like Figure 2 and Figure 4In this embodiment, the bottom end of the filter box 7 is fixedly connected to a servo motor 9, and the output end of the servo motor 9 is fixedly connected to a scraper 14. The servo motor 9 drives the scraper 14 to rotate periodically in forward and reverse directions, so as to clean the surface of the filter bag 12, ensure normal filtering efficiency, and facilitate the collection of impurities such as dust in the collection box 8.

[0030] like Figure 2 and Figure 4 In this embodiment, the bottom end of the filter box 7 is fixedly connected with a collecting box 8, and the top end of the collecting box 8 extends through the inside of the filter box 7 to collect the scraped dust and other impurities for subsequent cleaning.

[0031] like Figure 2 and Figure 5 In this embodiment, ventilation holes 16 are evenly arranged on the top of the fixed disk 15 outside the filter bag 12, and an outlet pipe 6 that passes through the filter box 7 is fixedly connected to the middle position of the top of the fixed disk 15 to ensure that the biomass gasification gas can enter the inside of the filter bag 12 from the outside.

[0032] It can be understood that the biomass fuel combustion gasification device can adjust the position of the conical cylinder 10 on the fixed plate 11 to achieve closure or opening, and ultimately keep it closed from the outside world during the feeding process, which effectively avoids gas leakage. At the same time, it can filter the generated biomass gasification gas and achieve self-cleaning to ensure a good filtering effect.

[0033] The complete usage steps and working principle of the utility model are as follows:

[0034] First, when biomass fuel needs to be added, the driving motor 3 is first operated to make the conical cylinder 10 and the notch 13 on the fixed plate 11 not overlap, and then the biomass fuel is added through the feed pipe 4, and then the valve is closed, and the driving motor 3 is operated to make the notch 13 on the conical cylinder 10 and the fixed plate 11 overlap, at this time, the biomass fuel can be added to the gasifier 1 through the notch 13, and in this process, it is always kept closed from the outside, so that gas leakage is well avoided;

[0035] When the biomass fuel is combined with the gasifying agent to carry out chemical reactions such as high-temperature pyrolysis, oxidation and reduction to generate biomass gasification gas, the biomass gasification gas enters the filter box 7 through the air duct 5, and then acts on the filter bag 12 through the air vent 16. After being filtered by the filter bag 12, it is discharged from the air outlet pipe 6. In this process, impurities such as dust are well avoided from being brought out. Subsequently, the scraper 14 can be driven by the servo motor 9 to rotate forward and reverse periodically to clean the surface of the filter bag 12, thereby ensuring normal filtering efficiency and facilitating the collection of impurities such as dust in the collection box 8.
