Description

Technical Field

[0001] This invention relates to the field of power plant environmental protection technology, specifically to a high-efficiency dust removal and dehumidification device for power plants. Background Technology

[0002] During the daily operation of power plants, the internal air environment generally suffers from serious particulate matter pollution and high concentrations of water vapor. Specifically, the coal conveying system, pulverizing system, combustion system, and ash and slag treatment system in power plants continuously generate a large amount of fine dust; at the same time, due to factors such as equipment heat dissipation, alternating hot and cold temperatures, flushing operations, and external meteorological conditions, the water vapor content in the air remains at a high level for a long period of time.

[0003] If such dusty and humid air is not effectively treated, it will have multiple adverse effects on the safe operation of power plants and the lifespan of equipment. First, dust and moisture adhering together on the surface of electrical equipment will significantly reduce insulation performance, increase the risk of leakage and flashover, and in severe cases, induce short circuit accidents. Second, the synergistic effect of water vapor and corrosive substances in dust (such as sulfides and chloride ions) will accelerate the corrosion and aging of metal parts, cable trays, and internal components of control cabinets. In addition, high-concentration dust environments also pose a potential threat to the respiratory health of on-site maintenance personnel.

[0004] Currently, power plants typically employ relatively independent dust removal equipment (such as electrostatic precipitators and bag filters) and dehumidification equipment (such as refrigerated dehumidifiers and rotary dehumidifiers) for air treatment. However, these traditional devices have significant shortcomings: firstly, their functions are limited, failing to simultaneously and efficiently remove dust and moisture; secondly, there are mismatches in processing capacity and cumulative energy consumption among the devices, resulting in low overall energy efficiency; and thirdly, under the complex operating conditions of power plants—high temperature, high humidity, and high dust levels—traditional equipment exhibits poor operational stability, is prone to clogging, condensation, or failure, and struggles to meet the demands for continuous, stable, and efficient air purification. No solutions have yet been proposed to address these technical issues. Summary of the Invention

[0020] Example Please see Figure 1-4 As shown, the present invention proposes a technical solution for a high-efficiency dust removal and dehumidification device for power plants: A high-efficiency dust removal and dehumidification device for power plants includes a housing 1, a partition 2 installed inside the housing 1, a filter 3 installed on one side of the top of the partition 2, a filter screen installed inside the filter 3, a condenser 4 installed on one side of the filter 3, a fan panel 5 and an evaporator 6 arranged sequentially between the filter 3 and the condenser 4, a plurality of fans 501 installed on the fan panel 5, a compressor 7 installed at the bottom of the partition 2, a plurality of guide plates 8 installed on the other side of the filter 3, the exhaust port of the compressor 7 connected to the air inlet of the condenser 4 through a connecting pipe one, the liquid outlet of the condenser 4 connected to the liquid inlet of the evaporator 6 through a connecting pipe two, the air outlet of the evaporator 6 connected to the air return port of the compressor 7 through a connecting pipe three, a water receiving tray 9 installed below the evaporator 6, a power distribution board 10 installed on one side of the compressor 7, and a power supply 11 installed on the power distribution board 10; Temperature and humidity sensor 12 and differential pressure sensor 13 are also installed on the inner surface of housing 1. Controller 14 is also installed on the power distribution board 10. Dew point sensor 15 and particulate matter concentration sensor 16 are installed on the top of housing 1. Controller 14 is electrically connected to filter 3, condenser 4, fan 501, compressor 7, evaporator 6, dew point sensor 15 and particulate matter concentration sensor 16 respectively.

[0021] In this embodiment, the housing 1 and partition 2 provide support and manage the airflow path; the filter 3 and filter screen can perform preliminary dust removal on the gas entering the housing 1, intercepting large particles and protecting the evaporator 6 and fan 501 from contamination; the condenser 4, evaporator 6, and compressor 7 constitute a refrigeration cycle system; the compressor 7 compresses the refrigerant, which is liquefied by releasing heat in the condenser 4, and then evaporates by absorbing heat in the evaporator 6, thereby achieving cooling and dehumidification; connecting pipes one, two, and three are used to transport the refrigerant; several fans 501 on the fan panel 5 force the airflow to pass through the filter in sequence. The system includes a filter 3, an evaporator 6, and a condenser 4, which improve heat exchange and dehumidification efficiency.

[0022] Please see Figure 1-2 As shown, a cabinet door 17 is further provided below the air guide plate 8. The cabinet door 17 is connected to the housing 1 by a hinge.

[0024] Furthermore, the controller 14 integrates a humidity control module and an energy-saving adjustment module.

[0025] In this embodiment, the humidity control module and the energy-saving adjustment module can optimize energy consumption and dehumidification performance.

[0026] Please see Figure 1 As shown, a remote communication module 19 is further provided on the outside of the housing 1. The remote communication module 19 is electrically connected to the controller 14. The remote communication module 19 is one of a 4G / 5G wireless communication module or an RS485 wired communication module.

[0027] In this embodiment, the remote communication module 19 can realize data exchange between the device and the host computer or cloud platform, and supports remote monitoring, alarm and parameter adjustment.

[0028] Furthermore, the evaporator 6 includes a housing, inside which heat exchange tubes and fins are provided, the fins being hydrophilic aluminum foil fins.

[0029] In this embodiment, the hydrophilic aluminum foil fins prevent water droplets from condensing into a film, thereby improving heat exchange efficiency and reducing wind resistance.

[0030] Please see Figure 4 As shown, further, several guide vanes 8 are inclined downwards, and several guide vanes 8 are distributed parallel to each other at equal intervals, and the distance between two adjacent guide vanes 8 is 5-15cm.

[0031] In this embodiment, the airflow is evenly distributed and guided to avoid turbulence, thereby improving the surface contact efficiency of the evaporator 6 and enhancing the dehumidification effect.

[0032] Please see Figure 2 As shown, furthermore, a drain pipe 20 is connected to the bottom of the water receiving tray 9, and a one-way valve is installed on the drain pipe 20.

[0033] In this embodiment, the drain pipe 20 discharges the condensate in the water tray 9, and the one-way valve prevents external air or water from flowing back.

[0034] Please see Figure 2-3 As shown, the outer surfaces of connecting pipe 1, connecting pipe 2 and connecting pipe 3 are all wrapped with heat insulation sleeves, and a pressure gauge is installed on connecting pipe 1.

[0035] In this embodiment, the heat insulation sleeve can reduce energy loss, and the pressure gauge monitors the status.

[0036] Please see Figure 1-4 As shown, a handle is further installed on one side of the housing 1.

[0037] In this embodiment, the handle facilitates the movement of the housing 1.

[0038] Furthermore, the housing 1 is made of metal, and the outer surface of the housing 1 is coated with an anti-corrosion layer.

[0039] In this embodiment, the housing 1 is supported by an aluminum alloy, and the anti-corrosion layer can extend the service life of the housing 1, making it suitable for the complex environment of power plants.

[0040] Working principle of the invention: Dust-laden, humid air enters the housing 1 under the forced suction of multiple fans 501 on the fan panel 5. The airflow first passes through the filter 3 and its internal filter screen to intercept large dust particles, preventing subsequent evaporator 6, fans 501 and other components from becoming clogged or worn. Airflow passes through several downward-sloping, equidistant parallel guide plates 8, ensuring uniform airflow distribution and avoiding turbulence. This ensures the airflow can fully and evenly sweep across the surface of the evaporator 6, improving heat exchange efficiency. The uniform airflow enters the evaporator 6, which contains a low-temperature refrigerant. The surface temperature (hydrophilic aluminum foil fins) of the refrigerant is lower than the air dew point temperature. Water vapor in the air condenses into water droplets on the fin surface, which slide down to the water collection tray 9 below, thus achieving deep dehumidification. The hydrophilic aluminum foil fins prevent water droplet film formation, ensuring heat exchange efficiency and reducing wind resistance. The dehumidified cold air continues to flow through the condenser 4, where it exchanges heat with the high-temperature refrigerant. The air is appropriately heated (reducing relative humidity) and finally discharged from the shell 1 in a dry, warm, and clean state, avoiding discomfort or secondary condensation caused by excessively cold exhaust air. The condensate collected in the water collection tray 9 is discharged through the drain pipe 20 connected to the bottom. The one-way valve on the drain pipe 20 prevents external air or sewage from flowing back into the device.

[0041] Compressor 7 compresses the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas, which is then discharged to condenser 4. In condenser 4, the high-temperature, high-pressure refrigerant gas releases heat to the air flowing through it, cooling and liquefying into a high-pressure, room-temperature liquid. The liquid refrigerant enters evaporator 6 through connecting pipe 2, absorbs heat from the air flowing through it, and evaporates, becoming a low-temperature, low-pressure gas, thus achieving air cooling and dehumidification. The refrigerant gas exiting evaporator 6 returns to the compressor 7's return port through connecting pipe 3, completing the refrigeration cycle. Connecting pipes 1, 2, and 3 are externally wrapped with heat-insulating sleeves to reduce cold / heat losses. A pressure gauge installed on connecting pipe 1 is used to monitor the pressure.

[0042] The controller 14 automatically starts, stops, or adjusts the working status of the filter 3, condenser 4, fan 501, compressor 7, and evaporator 6 based on signals such as temperature, humidity, dew point, pressure difference, and particulate matter concentration to achieve efficient and energy-saving dust and dehumidification. When the humidity meets the standard and the dust concentration is low, it automatically reduces the frequency of fan 501 or the power of compressor 7 to optimize energy consumption.

[0043] Parameter settings, status checks, and alarm queries can be performed via the touch screen 18 on the cabinet door 17; the cabinet door sealing strip ensures airtightness, the heat dissipation vent assists in internal heat dissipation, and the remote communication module 19 (4G / 5G or RS485) uploads the data from the controller 14 to the host computer or cloud platform, supporting remote start / stop, parameter adjustment, and fault alarm push, which is suitable for unattended or centralized monitoring scenarios in power plants.
