Abstract
Description
Technical Field
[0001] This invention relates to the field of gas generator technology, specifically to an intake filter structure for a gas generator set. Background Technology
[0002] A gas generator set is a power device that uses combustible gases such as natural gas and biogas as fuel to generate electricity through an internal combustion engine driving a generator. The air intake filtration structure of a gas generator set is responsible for effectively intercepting dust, impurities, and other pollutants in the air, thereby ensuring that the air entering the gas generator set is highly clean. This prevents particulate matter from causing wear or corrosion to internal precision components such as cylinders, pistons, and valves. Its significance lies in improving the operational reliability and service life of the gas generator set, while reducing the frequency of maintenance and repair costs caused by intake air contamination, ultimately ensuring that the unit can operate continuously in a highly efficient and stable state.
[0003] The existing air intake filtration structure of gas generator sets has gradually revealed its shortcomings during use, mainly in the following aspects: Particles in the bends and shallow areas of the wave-like structure of air filters are difficult to remove. Specifically, the intake filtration structure of gas generator sets typically uses air filters to remove impurities from the air. To increase the filtration area, the outer wall of the filter is designed with a wave-like structure. During the air purification process, some particles gradually accumulate in the bends of the wave-like structure. Due to repeated airflow impact and the interlocking of particles, these particles are easily compacted to form a relatively stable deposit layer. At the same time, some fine particles will further enter the shallow area of the filter fibers with the airflow. Currently, the common method for cleaning filters is to use compressed air for backflushing. However, during backflushing, particles in the bends of the wave-like structure are in a "shielded area" of airflow and are difficult to be swept away by the forward blowing force. Fine particles that have entered the shallow layer of the filter are also not easily carried out by the reverse airflow due to the adhesion of the filter fiber surface, resulting in limited cleaning effect.
[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention
[0005] To address the shortcomings of existing technologies, the present invention aims to provide an intake filter structure for gas generator sets. This intake filter structure, when cleaning the filter element, not only alters the spatial morphology of the bends within the wave-like structure, thereby disrupting the existing particulate matter buildup in that area, but also generates vibration by striking the filter element, effectively breaking the adhesion between the particulate matter and the filter element fibers. This significantly enhances the ability to remove particulate matter from the bends and shallow areas within the wave-like structure of the filter element, achieving a more thorough and efficient cleaning effect.

A lifting plate is vertically raised and lowered at the bottom of the bottom plate, and several sealing plates are fixedly provided at the top of the lifting plate.
[0008] As an optimized solution, a number of lifting and telescopic cylinders are fixedly installed at the bottom of the base plate, and the telescopic ends of the lifting and telescopic cylinders are fixedly connected to the lifting plate.
[0009] As an optimized solution, the mounting groove is provided with an internal gear ring that is rotatably connected to the base plate. The outer arc plate is detachably connected to the internal gear ring. A control motor is fixedly provided at the bottom of the base plate. The output shaft of the control motor extends into the mounting groove and is fixedly installed with a gear that meshes with the internal gear ring.
[0010] As an optimized solution, the top of the base plate is provided with a rotating shaft, and a number of fixing plates are fixedly provided on the outer wall of the rotating shaft. A connecting rod is slidably provided at the end of the fixing plate. The connecting rod is fixedly connected to the inner arc plate. A first compression spring is provided inside the fixing plate. One end of the connecting rod extends into the fixing plate and abuts against the first compression spring.
[0011] As an optimized solution, a plurality of fixed cylinders are fixedly provided on the outer wall of the rotating shaft, and a sliding rod is slidably provided at the end of the fixed cylinder. The sliding rod is fixedly connected to the vertical rod, and a second compression spring is provided inside the fixed cylinder. One end of the sliding rod extends into the fixed cylinder and abuts against the second compression spring.
[0012] As an optimized solution, a fixing ring is fixedly provided at the bottom of the top plate and the top of the bottom plate. Several guide plates are fixedly provided on the inner wall of the fixing ring. One end of the guide plate has an arc-shaped structure.

[0015] As an optimized solution, the exhaust pipe is connected to the gas generator set intake pipe and an external compressed air tank via a three-way valve.
[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When cleaning the filter element, keep the inlet valve closed, connect the outlet pipe to the external compressed air tank, and lower the sealing plate with the lifting plate. This opens the dust discharge trough, allowing compressed air to backflush the filter element. Simultaneously, the control motor drives the outer arc-shaped plate to rotate, and the agitator plate moves the outer bend of the filter element's corrugated structure, causing a change in the space at the inner bend of the corrugated structure. This breaks down the accumulated particulate matter layer at that point, causing it to detach from the filter element. The drive motor then rotates the inner arc-shaped plate and the vertical rod. With the cooperation of the first compression spring, the inner arc-shaped plate adheres tightly to the inner wall of the filter element. When the vertical rod contacts the arc-shaped structure of the guide plate, it slides inward and compresses the second compression spring. After the vertical rod separates from the guide plate... Under the reset action of the second compression spring, the striking ball strikes the inner arc plate, causing the filter element to vibrate. This disrupts the adhesion between the particles and the filter element fibers. Combined with the backflush of compressed air, the particles in the shallow area of the filter element are cleared out. When cleaning the filter element, this air intake filtration structure not only changes the spatial shape of the bends in the wave structure, thereby destroying the particle accumulation layer that has formed in that area, but also vibrates the filter element by striking it, effectively disrupting the adhesion between the particles and the filter element fibers. This significantly improves the ability to remove particles from the bends and shallow areas of the wave structure of the filter element, achieving a more thorough and efficient cleaning effect. 2. The removed particulate matter enters the dust collection hopper through the dust discharge trough for centralized collection, thus avoiding pollution of the surrounding air and working environment by particulate matter; 3. By setting through holes on the inner and outer arc plates, the loss of gas flow area caused by solid obstruction can be effectively reduced. Attached Figure Description

[0031] The base plate 10 is connected to the top plate 2 via several connecting plates 11.
[0032] The working principle of this device is as follows: When providing clean air to the gas generator set, the outlet pipe 9 is connected to the gas generator set inlet pipe. External air enters the housing 1 through the inlet valve 7. When the air passes through the filter element 8, it is effectively purified. The purified air enters the gas generator set inlet pipe through the outlet pipe 9, thereby supplying the required clean air to the gas generator set. When cleaning filter element 8, the air inlet valve 7 remains closed, the air outlet pipe 9 is connected to an external compressed air tank, the lifting plate 41 moves the sealing plate 40 downward, the dust discharge trough 16 opens, and compressed air backflushs the filter element 8. At the same time, the control motor 38 drives the outer arc plate 15 to rotate, and the actuating plate 20 actuates the outer bend of the wave structure of the filter element 8, causing a change in the space at the inner bend of the wave structure of the filter element 8, thereby breaking the accumulated particulate matter layer at that location and causing it to detach from the filter element 8. The drive motor 21 drives the inner arc plate 12 and the vertical rod 25 to rotate. With the cooperation of the first compression spring 28, the inner arc plate 12 is tightly attached to the inner wall of the filter element 8. When the vertical rod 25 contacts the arc structure of the guide plate 34, the vertical rod 25 slides inward and compresses the second compression spring 31. After the vertical rod 25 separates from the guide plate 34, under the reset action of the second compression spring 31, the striking ball 27 strikes the inner arc plate 12, causing the filter element 8 to vibrate, thereby breaking the adhesion between the particles and the filter element fibers. Combined with the backflush of compressed air, the particles in the shallow area of the filter element 8 are cleared out. When cleaning the filter element 8, this air intake filtration structure can not only change the spatial shape of the bends in the wave structure, thereby breaking the particle accumulation layer that has been formed in that area, but also make the filter element 8 vibrate by striking it, effectively breaking the adhesion between the particles and the filter element fibers. This significantly improves the ability to remove particles from the bends and shallow areas of the wave structure of the filter element 8, achieving a more thorough and efficient cleaning effect. The removed particulate matter enters the dust collection hopper 5 through the dust discharge trough 16 for centralized collection, thus avoiding pollution of the surrounding air and working environment by particulate matter. By providing through holes 14 on the inner arc plate 12 and the outer arc plate 15, the loss of gas flow area caused by solid obstruction can be effectively reduced.
