Description

Technical Field

[0001] This utility model relates to the field of steam generator technology, and in particular to a biomass pellet steam generator. Background Technology

[0002] A biomass pellet steam generator is a steam generator that uses biomass pellets as fuel. It is an energy conversion device and a new type of energy-saving and environmentally friendly thermal energy device that can replace traditional steam boilers. It releases energy by burning biomass pellets to heat the water in the steam generator body, thereby producing hot water or steam.

[0003] A search revealed that patents with publication numbers CN221258820U and CN222527611U both disclose a biomass pellet steam generator. When these two biomass pellet steam generators are in use, the exhaust gas produced by combustion is directly discharged, which is detrimental to environmental protection and human health. At the same time, the exhaust port will generate some noise, which is also detrimental to human health.

[0004] To address the above problems, this utility model document proposes a biomass pellet steam generator. Utility Model Content

[0005] This invention provides a biomass pellet steam generator, which solves the shortcomings of existing biomass pellet steam generators, such as the direct discharge of exhaust gas generated during combustion, which is detrimental to environmental protection and human health, and the noise generated at the exhaust port, which is also detrimental to human health.

[0006] This utility model provides the following technical solution:

[0007] A biomass pellet steam generator, comprising:

[0008] The biomass pellet steam generator body has a steam discharge pipe and an exhaust gas discharge pipe connected to its top. The other end of the exhaust gas discharge pipe is connected to a filter box. The output port of the filter box is connected to a double-walled pipe, and the interlayer cavity of the double-walled pipe is filled with glass wool.

[0009] The filter assembly, located inside the filter box, is used to filter the exhaust gas.

[0010] The noise reduction component, located on the double-walled pipe, is used to improve the noise reduction effect.

[0011] In one possible design, the filtration assembly includes a particulate filter for filtering particulate impurities in exhaust gas and a photocatalytic filter for removing harmful gases from exhaust gas, which are slidably mounted on a groove inside the filter box. The particulate filter is positioned near the inlet of the filter box. An ultraviolet lamp for promoting the recovery of the catalytic ability of the photocatalytic filter is fixedly installed on the inner wall of the filter box. The ultraviolet lamp is located below the double-walled pipe.

[0012] In one possible design, an electric push rod is provided between the particulate filter and the photocatalytic filter to impact the particulate filter and prevent its filter pores from becoming clogged. A fixing plate is fixedly provided on the inner wall of the filter box, and one end of the electric push rod is fixedly installed on the side wall of the fixing plate.

[0013] In one possible design, the silencing assembly includes a silencing pipe connected to the other end of a double-walled pipe, with two rows of silencing plates fixedly arranged in an alternating pattern inside the silencing pipe, and a three-way catalytic honeycomb tube for further gas purification fixedly arranged inside the silencing pipe, the three-way catalytic honeycomb tube being located between the silencing plates and the double-walled pipe.

[0014] In one possible design, a reinforcing steel plate is fixedly installed at the bottom of the biomass pellet steam generator body. Universal wheels and leveling screws are fixedly installed at the four corners of the bottom of the reinforcing steel plate, and a matching hollow support is threaded onto the screw.

[0015] In one possible design, hooks for easy hoisting are fixed at the four corners of the top of the biomass pellet steam generator body.

[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0017] The working principle and usage process of this technical solution are as follows:

[0018] During use, the operator starts the biomass pellet steam generator and feeds the biomass pellet fuel into the generator body. The biomass pellets burn in the generator body, producing steam and exhaust gas. The steam is discharged through the steam exhaust pipe for heating, process heating, and other purposes. The exhaust gas produced by combustion enters the filter box through the exhaust gas exhaust pipe. In the filter box, the exhaust gas first passes through the pellet filter screen, which intercepts particulate impurities in the exhaust gas and prevents them from entering the atmosphere. The electric push rod can be activated periodically or according to the clogging of the pellet filter screen. The extension end of the electric push rod collides with the pellet filter screen, generating vibration, thereby removing impurities attached to the filter holes and maintaining the filtration efficiency of the pellet filter screen.

[0019] Subsequently, the exhaust gas passes through a photocatalytic filter, which catalytically decomposes harmful gases in the exhaust gas, converting them into harmless substances. Under ultraviolet light, the photocatalytic filter's catalytic capacity is restored, slowing down the loss of its activated medium and enabling it to be regenerated and reused, thus achieving long-term use. The exhaust gas purified by the filter box enters a double-walled pipe. The glass wool filling the interlayer of the double-walled pipe reduces noise, minimizing noise pollution during exhaust gas emission. The exhaust gas continues to flow into a silencer pipe, where two rows of staggered sound-absorbing plates further absorb and reduce noise. At the same time, the three-way catalytic honeycomb tube inside the silencer pipe further purifies the exhaust gas, ensuring that the emitted exhaust gas meets national environmental protection standards.

[0020] This utility model has the following beneficial effects:

[0021] This invention effectively removes particulate impurities and harmful gases from exhaust gas through dual filtration of particulate filter and photocatalytic filter, as well as further purification by three-way catalytic honeycomb tube, thereby reducing environmental pollution and protecting air quality.

[0022] In this invention, the glass wool inside the double-walled pipe and the sound-absorbing plate inside the sound-absorbing pipe work together to significantly reduce noise pollution during exhaust gas emission, improve the working environment, and protect the hearing health of operators.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0032] Example 1

[0033] Please refer to Figure 1-5 A biomass pellet steam generator, used in the field of steam generators, includes:

[0034] The biomass pellet steam generator body 1, model ZFQ2.0-0.09-SCI, is the core component. Its top is connected to a steam exhaust pipe 2 and a waste gas exhaust pipe 3. The steam exhaust pipe 2 discharges the generated steam, while the waste gas exhaust pipe 3 guides the waste gas generated during combustion to the filter box 9. To facilitate movement and leveling, a reinforcing steel plate 4 is fixedly installed at the bottom of the biomass pellet steam generator body 1. Universal wheels 5 and leveling screws 6 are installed at the four corners of the bottom of the reinforcing steel plate 4. The screws 6 are threaded onto matching hollow support seats 7. By screwing the four hollow support seats 7 into contact with the ground, the equipment can be placed horizontally and stably. Hooks 8 are also fixedly installed at the four corners of the top of the biomass pellet steam generator body 1. These hooks 8 facilitate handling and installation using hoisting equipment.

[0035] The filter box 9 is equipped with a filtration assembly for purifying exhaust gas. Specifically, the filtration assembly includes a particulate filter 10 and a photocatalytic filter 11, which are slidably installed on the slide groove 20 inside the filter box 9. This sliding installation structure facilitates the replacement of the particulate filter 10 and the photocatalytic filter 11. The particulate filter 10 is located near the inlet of the filter box 9 and is used for preliminary filtration of particulate impurities in the exhaust gas. The photocatalytic filter 11 further removes harmful gases from the exhaust gas. The photocatalytic filter 11 is made by lattice doping of nano-sized powder with various nano-sized photosensitive semiconductor media. It is made by ensuring sufficient air permeability and contact, and then mixing and processing with a carrier. It can effectively remove harmful gases and odors such as carbon monoxide, nitrogen oxides, hydrocarbons, aldehydes, and benzene from exhaust gas, and decompose them into harmless carbon dioxide and water. In order to enhance the catalytic ability of photocatalytic filter 11, ultraviolet lamp 12 is fixedly installed on the inner wall of filter box 9. It is located below double-wall pipe 15. Under the irradiation of ultraviolet lamp 12, it can promote the recovery of the catalytic ability of photocatalytic filter 11, reduce the loss of its activated medium, and regenerate it for reuse, thereby achieving the effect of long-term use.

[0036] The interlayer cavity of the double-walled pipe 15 is filled with glass wool 16, which has good heat insulation and noise reduction performance. In order to improve the noise reduction effect, a sound-absorbing component is also installed on the double-walled pipe 15. The sound-absorbing component includes a sound-absorbing pipe 17 connected to the other end of the double-walled pipe 15. Two rows of sound-absorbing plates 18 are fixedly arranged in an alternating manner inside the sound-absorbing pipe 17. Through their specific arrangement and structural design, these sound-absorbing plates 18 can effectively absorb and reflect sound waves, thereby effectively absorbing and reducing the noise generated when exhaust gas is emitted. A three-way catalytic honeycomb tube 19 is also fixedly installed inside the sound-absorbing pipe 17. It is located between the sound-absorbing plates 18 and the double-walled pipe 15 and is used to further purify the exhaust gas to improve the purification and filtration effect.

[0037] Example 2

[0038] Improvements based on Example 1:

[0039] Please refer to Figure 3-4 To prevent the filter holes of the particulate filter 10 from becoming clogged, an electric push rod 13 is installed between the particulate filter 10 and the photocatalytic filter 11. One end of the electric push rod 13 is fixedly installed on the side wall of the fixing plate 14, which is fixedly installed on the inner wall of the filter box 9. When the impurities on the particulate filter 10 accumulate to a certain extent, the electric push rod 13 can continuously collide with the particulate filter 10 to vibrate it, thereby knocking off the impurities attached to the filter holes and ensuring the filtration effect.

[0040] However, as is well known to those skilled in the art, the working principles and wiring methods of the biomass pellet steam generator body 1, ultraviolet lamp 12 and electric push rod 13 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0041] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.
