Description

[0002] At present, many places in the field of air purification use electrostatic filters + fan linkage purification devices, which use high-voltage electrostatic filters to charge particles, and then are captured by dust collecting plates.

At the same time, it will also cause pollution to the differential pressure sensor installed at the input end of the electrostatic filter, causing the differential pressure sensor to fail to detect, making it impossible for the electrostatic filter to start purification.

[0014] A control method for a vertically mounted electrostatic filter implemented based on a vertically mounted electrostatic filter comprises the following steps:

[0015] S1: Start the electrostatic filter, and the monitoring equipment monitors the oil fume emission value inside the electrostatic filter, the operating status of the electrostatic filter and the operating status of the fan in real time, and forms monitoring data and uploads it to the equipment control system;

[0016] The monitoring data include: monitoring oil fume emission data, monitoring electrostatic filter operation data and monitoring fan operation data;

[0032] The beneficial effects achieved by the present invention are:

[0033] 1. Compared with the existing vertical electrostatic filters on the market, the present invention adopts the V-shaped design of the guide plate. The oil smoke changes its flow direction under the upper suction force and hits the plate surface multiple times. The inertia causes large oil droplets to adhere to the plate surface, achieving initial and efficient separation. The inclined design of the oil-blocking plate allows the oil droplets to slide smoothly and be discharged into the oil storage tank through the oil drain hole to prevent oil accumulation and keep the system clean and efficient. This design can also prevent oil backflow, ensure continuous and stable filtration, initially filter out large oil droplets, reduce the burden of subsequent electrostatic and honeycomb filters, and improve filtration efficiency.

[0034] 2. The gas-liquid filter uses gas-liquid separation technology. When the oil mist gas passes through the multi-layer interlaced network, inertia causes the mist to adhere to the surface of the filaments and diffuse. Under the action of gravity, the droplets flow along the filaments to the interlacing point, increase in size and fall, achieving efficient purification of oil smoke, further reducing the burden of subsequent static electricity and honeycomb filters, and improving filtration efficiency.

[0035] 3. The setting of emergency exhaust air valve ensures automatic smoke exhaust in case of equipment failure or power outage, ensuring normal use by customers.

[0036] 4. The bending design at the top of the louver effectively prevents the intrusion of rain and dust, reduces kinetic energy impact, and protects the inside of the filter.

[0037] 5. By raising the fan position, the fan's rain protection capacity is improved. At the same time, by sealing the trumpet-shaped connection port at the fan input end, rain or dust is isolated to further prevent rain or dust from entering the filter.

[0038] 6. By setting the bottom end of the shutter outer frame and the bottom end of the outer wall of the connecting port to be parallel, and providing a drainage port at the bottom end of the shutter outer frame, rainwater isolated by the connecting port can be discharged.

[0039] 7. The M-shaped structure installation setting effectively increases the contact area of ​​the honeycomb filter plate in a limited space, reduces resistance, and improves the purification efficiency of the product.

[0040] 8. Real-time monitoring of key indicators of electrostatic filters, such as oil fume emissions and equipment operating status, ensures optimal operation and extends life. Automatic alarm and data transmission to the cloud in case of abnormality facilitates remote monitoring and maintenance, reducing the risk of production interruption. Electrostatic filters reduce oil fume emissions, improve work efficiency, and meet environmental standards. Intelligent voltage regulation avoids energy waste, reduces failure rate and maintenance costs, and improves economic benefits. Automated monitoring reduces human errors, improves system stability and reliability, and ensures safe operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The present invention is further described below in conjunction with the accompanying drawings.

[0053] Embodiment 1

[0054] like Figure 1-7 As shown, the patent of the present invention discloses a vertically mounted electrostatic filter, comprising: a shell 1 with an opening at the bottom, an air outlet is arranged circumferentially on the upper part of the outer wall of the shell 1, an oil blocking mechanism, an electrostatic filter 4, a honeycomb filter 3 and a fan 2 are sequentially installed in the shell 1 from bottom to top, the oil blocking mechanism comprises an oil blocking plate 5, an oil storage tank 13 and an oil discharge device 14 arranged downwardly inclined from back to front, the oil blocking plate 5 is composed of an outer frame 51 with a U-shaped cross-section and an inward opening and two guide plate assemblies symmetrically arranged in the outer frame 51 from top to bottom, the guide plate assembly located above comprises a plurality of V-shaped guide plates 52 arranged at equal intervals along the inner wall of the outer frame 51 and opening downward, and the outer wall of the end of the V-shaped guide plate 52 is formed by two symmetrically arranged The connecting piece 53 is fixedly connected to the inner wall of the outer frame 51, the layout of the V-shaped guide plates 52 of the upper and lower guide plate assemblies is staggered, and the outer wall of the outer frame 51 located at the front end of the V-shaped guide plate 52 is provided with an oil drain hole 54 corresponding to the angle of the V-shaped guide plate 52, and an L-shaped partition 12 is integrally arranged in the shell 1 at the bottom of the output end of the oil baffle plate 5, and the top of the partition 12 is sealed and fixed to the bottom end of the outer frame 51, and the partition 12 and the inner wall of the shell 1 form an oil storage tank 13, and the oil drain device 14 is installed at the bottom end of the outer wall of the front side of the shell 1 and is connected to the lower part of the inner wall of the oil storage tank 13, and the input ends of the electrostatic filter 4, the honeycomb filter 3 and the fan 2 are all sealed and connected to the inner wall of the shell 1.

[0055] Based on the above structure, Figure 1-7 As shown, when in use, the fan 2 runs and generates suction, sucking the air to be filtered at the air inlet into the filter for filtration, and finally discharged through the vent. During this process, the oil blocking plate 5 performs preliminary filtration on the air containing oil smoke and prevents the filtered oil from flowing back. The electrostatic filter 4 performs secondary filtration on the air containing oil smoke, collects the oil smoke particles through the electric field, and generates a small amount of ozone during operation. The ozone reacts with the smoke to remove most of the odor in the smoke. Furthermore, the honeycomb filter 3 performs tertiary filtration on the air containing oil smoke to effectively capture the oil droplets in the smoke.

[0056] Specifically, in the initial filtration, due to the V-shaped setting of the guide plate 52, the guide plate 52 located at the bottom will guide the oil smoke-containing air to the middle part of the guide plate 52 located at the top. When the oil smoke-containing air contacts the inner wall of the guide plate 52 located at the top, the fan 2 generates an upward suction force, and the oil smoke-containing air is forced to change its flow direction along the inner wall of the guide plate 52 located at the top and collide with the surface of the guide plate 52 many times. During the collision, large oil particles in the oil smoke are thrown to the surface of the guide plate 52 due to inertia, and the large oil particles on the guide plate 52 gradually gather and form oil droplets. The inclined setting of the oil blocking plate 5 causes the oil droplets to slide down along the guide plate 52 until the oil droplets finally gather at the bottom of the outer frame 51, and are discharged through the oil discharge hole 54 and fall into the oil storage tank 13 for storage.

[0057] Further, such as Figure 7 As shown, due to the staggered layout of the V-shaped guide plates 52 of the upper and lower guide plate assemblies, the oil droplets on the upper guide plate 52 will flow to the two sides of the guide plate 52 due to the V-shaped setting of the guide plate 52, and finally fall into the guide plate 52 located below, and slide down along the guide plate 52, and be discharged into the oil storage tank 13 for storage. At the same time, the oil particles filtered by the electrostatic filter 4 and the honeycomb filter 3 during long-term filtration will also form oil droplets. The vertical installation of the electrostatic filter allows the oil droplets to fall, and the oil blocking plate 5 blocks, collects, and guides the oil droplets, and discharges them into the oil storage tank 13. The oil discharge device 14 is provided to discharge the oil in the oil storage tank 13 regularly.

[0058] Further, such as Figure 3 and 8 As shown, in order to further reduce the direct entry of large particles into the electrostatic filter, the oil blocking mechanism also includes a primary filter 6 installed at the input end of the electrostatic filter 4, and the primary filter 6 is composed of multiple layers of gas-liquid nets stacked horizontally and vertically;

[0059] Specifically, the working principle of the gas-liquid filter is mainly based on gas-liquid separation technology. When the gas with oil mist passes through multiple layers of gas-liquid mesh stacked horizontally and vertically, the mist collides with the filaments and adheres to the surface of the filaments due to the inertia of the oil mist. The mist on the surface of the filaments further diffuses and forms larger droplets under the action of gravity, flowing along the filaments to the intersection. Due to the wettability of the filaments, the surface tension of the liquid and the capillary action of the filaments, the droplets gradually increase until their own weight exceeds the combined force of the buoyancy of the rising gas and the surface tension of the liquid, and then they are separated and fall, thereby achieving efficient purification of oil smoke.

[0060] Further, such as Figure 1 and 4 As shown, in order to avoid failure of normal smoke exhaust in case of power failure or equipment failure, an emergency exhaust air valve 15 is installed on the inner wall of the rear side of the housing 1 below the oil blocking plate 5, and an air outlet 151 is evenly arranged on the outer wall of the rear side of the housing 1 at the output end of the emergency exhaust air valve 15;

[0061] Specifically, the emergency exhaust air valve is a normally open self-resetting closed air valve, which automatically closes when the equipment is running. The air valve is linked to the fan. When the fan is turned on, the air valve is closed, and when the fan is turned off, the air valve is open. When the equipment cannot be operated or the power is cut off, the air valve is open and smoke can be automatically exhausted, thereby ensuring normal use by customers.

[0062] Further, such as Figure 1-4 As shown in FIG. 9 , in order to prevent rainwater or sand and dust from entering the filter through the shutter, a shutter 11 is installed in the air outlet. The shutter of the shutter 11 is set to be tilted downward from the inside to the outside, and the top of the shutter is provided with a bend set to be tilted upward from the inside to the outside. In actual use, when rainwater or sand and dust contact the shutter, they will splash due to inertia. The splashed rainwater or sand and dust will be blocked or change the movement angle when they contact the bend, thereby starting the effect of preventing sand and dust and rainwater.

[0063] At the same time, the redirection of rain or sand when it comes into contact with the blinds weakens the kinetic energy of the rain or sand when it falls. When the bends come into contact with the rain or sand, the kinetic energy of the rain or sand when it falls is further weakened, and the damage caused by the impact of rain or sand is also reduced.

[0064] Further, such as Figure 3-4 As shown, the fan 2 is installed on the top of the inner wall of the shell 1, and the input end is sealed and connected with a trumpet-shaped connecting port. The input end of the connecting port is sealed and connected to the inner wall of the shell 1, so that the rain protection ability of the fan is improved by raising the position of the fan 2, and the setting of the sealed connection to the trumpet-shaped connecting port isolates rainwater or dust, which can further prevent rainwater or dust from entering the filter.

[0065] Furthermore, in order to facilitate the discharge of rainwater isolated by the connecting port, the bottom end of the outer frame of the shutter 11 is parallel to the bottom end of the outer wall of the connecting port, and a drain outlet (not shown in the figure) is provided at the bottom end of the outer frame of the shutter 11. The rainwater isolated by the connecting port flows along the outer wall of the connecting port to the shutter and is discharged through the drain outlet.

[0066] Further, such as Figure 4 As shown, the honeycomb filter 3 is composed of four honeycomb filter plates, and the four honeycomb filter plates are installed in an M-shaped structure. The M-shaped structural installation arrangement effectively increases the contact area of ​​the honeycomb filter plates in a limited space, reduces resistance, and improves the purification efficiency of the product.

[0067] Further, such as Figure 1 and 10 As shown, in order to better monitor and control the electrostatic filter, the shell 1 has a built-in equipment control system, a monitoring device, a local control module and a 4G module. A display screen is provided on the front side of the shell 1. The electrostatic filter 4, the fan 2, the monitoring device, the local control module, the 4G module and the display screen are all connected to the equipment control system signal. The emergency exhaust air valve 15, the electrostatic filter 4, the fan 2, the monitoring device, the 4G module and the display screen are all electrically connected to the equipment control system. The equipment control system is connected to an external power supply, and the 4G module signal is connected to the cloud system.

[0075] The step S2 includes the following sub-steps:

[0076] S21: The equipment control system compares the monitored oil fume emission data with the standard oil fume emission value;

[0077] When the monitored oil fume emission data is greater than the standard oil fume emission data, the voltage of the electrostatic filter is increased;

[0078] When the monitored oil fume emission data is less than the standard oil fume emission data, the voltage of the electrostatic filter is lowered;

[0079] S22: The equipment control system continuously compares and monitors the oil fume emission data with the standard oil fume emission data;

[0080] When the monitored oil fume emission data is continuously greater than / less than the standard oil fume emission data, the equipment control system automatically alarms and enters step S3;

This efficient feedback mechanism ensures that the equipment always maintains the best operating state and effectively extends the life of the equipment; when the monitoring data continues to be abnormal, the system automatically triggers an alarm and transmits detailed data to the cloud in real time through the 4G module. This intelligent function greatly improves the convenience of remote monitoring and maintenance. The operation and maintenance team can respond quickly based on the alarm information and dispatch maintenance personnel to ensure that the problem is solved in a timely manner and minimize production interruptions. Risk; The electrostatic filter is committed to reducing oil fume emissions. By finely controlling the voltage of the electrostatic filter, efficient air purification is achieved, which not only creates a more comfortable and healthy working environment for employees, but also improves work efficiency and meets increasingly stringent environmental protection standards; the system intelligently adjusts the voltage of the electrostatic filter according to actual needs to effectively avoid energy waste. At the same time, by reducing equipment failure rate and maintenance costs, it helps enterprises achieve long-term energy conservation and cost reduction and improve economic benefits; the automated monitoring and alarm system greatly reduces the possibility of human operational errors, improves the stability and reliability of the entire system, and regular maintenance and overhaul work further ensures the safe operation of the equipment and reduces potential safety hazards.
