Description

Technical Field

[0001] This utility model belongs to the field of heat exchange technology, specifically relating to a spray humidification type skid-mounted air cooler. Background Technology

[0002] An air cooler is a device that uses ambient air as the cooling medium, flowing horizontally across the outside of finned tubes to cool or condense the high-temperature process fluid inside the tubes. It is also known as an "air-cooled heat exchanger" or simply "air cooler." Air coolers have wide applications in industrial production, covering many industries such as petrochemicals and power generation. Currently, with the continuous rise in energy costs and increasingly stringent environmental protection requirements, reducing the energy consumption of cooling systems and improving their operating efficiency have become important demands in industrial production.

[0003] Traditional air coolers primarily rely on natural or forced airflow for heat dissipation. However, in hot and arid regions, the heat dissipation efficiency of air coolers decreases significantly due to the high air temperature. Especially during the hot summer months, traditional air coolers may struggle to meet the actual cooling requirements of processes. Simultaneously, some regions face water scarcity, and traditional water-cooling systems consume enormous amounts of water, which is inconsistent with the current trend of sustainable water resource utilization.

[0004] The publicly disclosed document, "New Energy-Saving Humidifying Air Cooler" (application number 2024205557415), describes a humidifying air cooler. The cooler features an air outlet at the top of the housing and an air inlet on the side wall. An atomizing spray device is located inside the air inlet, and finned tube sheets are installed inside the housing corresponding to the air inlet. This type of equipment requires on-site installation, resulting in a large workload and significant construction difficulties. The matrix-distributed atomizing nozzles have limited coverage and the number of nozzles cannot be adjusted according to actual conditions. The nozzles are directly installed on the water supply line, resulting in short contact time between the atomized water droplets and the air, and limited space, leading to poor actual effectiveness and insufficient environmental friendliness and energy efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a spray humidification skid-mounted air cooler, which has the advantages of convenient installation, high mobility, high integration, convenient maintenance, environmental protection and energy saving.

[0006] The technical solution adopted by this utility model is as follows: a spray humidification type skid-mounted air cooler, including a box body, spray humidification systems are staggered on the inner walls of the left and right sides of the box body, anti-freeze louvers are provided on the outer walls of the left and right sides of the box body, an exhaust fan is provided on the top of the box body, an air cooler support is provided in the middle of the bottom of the box body, an inspection walkway is provided in the middle of the upper surface of the air cooler support, two air coolers are arranged in a V-shape in the box body, the bottom of the air coolers are located on both sides of the upper surface of the air cooler support, and the top of the air coolers are connected to the top of the inner walls of the left and right sides of the box body. The air coolers divide the interior of the box body into three chambers. A water collection tray is provided at the projection of the air cooler and is fixedly installed at the bottom of the box body.

[0007] The enclosure includes a bottom frame, with an air cooler support in the middle of the bottom frame. A water tray is placed on the upper surface of the bottom frame. Vertical columns are connected around the bottom frame, and the air cooler is connected to the top of the columns. A spray humidification system is fixedly installed on the inner walls of the left and right sides of the columns. Anti-freeze louvers are fixedly installed on the outer walls of the left and right sides of the columns. An induced draft fan is fixedly connected to the top of the columns.

[0008] The spray humidification system includes a control valve connected to a high-pressure hose. The control valve and high-pressure hose are located outside the housing. The high-pressure hose is connected to a spray water supply pipe, which is vertically connected to a spray distribution pipe. The spray distribution pipe is parallel to the column and located on one side of the housing. Multiple spray branch pipes are vertically connected to one side of the spray distribution pipe. The spray branch pipes are evenly distributed on the inner wall of one side of the column. Multiple downward-sloping high-pressure nozzles are installed inside the spray branch pipes. Two spray humidification systems are installed on the inner walls of the left and right sides of the column, respectively. The spray branch pipes and high-pressure nozzles of the two spray humidification systems are fixed to the inner wall of the column in a staggered arrangement.

[0009] The high-pressure nozzle is tilted downwards at an angle of 5-80°.

[0010] The control valves and antifreeze louvers are controlled manually, pneumatically, or electrically, respectively.

[0011] Anti-freeze louvers are made of non-metallic or metallic materials, such as fiberglass, galvanized sheet, magnesium-aluminum-zinc coated sheet, aluminum alloy, or stainless steel.

[0012] The air coolers are arranged in a V-shape, dividing the housing into a first chamber, a second chamber, and a third chamber. The first and second chambers are located between the air coolers and the columns, respectively, and the third chamber is located between the upper part of the two air coolers and the induced draft fan.

[0013] An inspection walkway is provided in the middle of the upper surface of the air cooler support, and fixed platforms are installed on both sides of the upper surface of the air cooler support at an angle corresponding to the tilt angle of the air cooler.

[0014] The spray humidification system is connected to the intelligent control system.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. A multi-branch spray distribution layout is adopted to provide an appropriate spray volume as needed, avoiding water waste and the risk of fan shutdown due to excessive spray volume. The spray branch pipes and high-pressure nozzles are arranged in a staggered manner, resulting in more uniform spraying. The high-pressure hose effectively prevents pipeline vibration from negatively impacting the equipment. The high-pressure nozzles are installed at a downward angle, utilizing the initial kinetic energy of the small droplets sprayed from the nozzles to create a curved trajectory for the droplets in the first and second chambers, forming a crossflow with the ambient air, thereby extending the space and time for air humidification and cooling, and improving the efficiency of humidification and cooling. The air cooler is raised to a certain height through the air cooler support, effectively reducing the dead zone of the ambient airflow and improving the heat exchange efficiency of the air cooler.

[0017] 2. The skid-mounted structure of this utility model is easy to transport as a whole, adapts to flexible layout, and has completed modular assembly and debugging in the factory. It has a short installation period, high integration, and the skid unit can be disassembled for maintenance. It is convenient to maintain, has high working stability, and is environmentally friendly and energy-saving.

[0018] 3. The spray humidification system is connected to an intelligent control system, enabling real-time monitoring of environmental, media, and fan parameters. Based on the monitored data, the system automatically adjusts the spray volume and spray time, further improving the accuracy and efficiency of humidification; it also allows for remote control of the spray humidification system.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-2As shown, a spray humidification type skid-mounted air cooler includes a housing 1, which includes a base frame 11. Vertical columns 12 are vertically connected to the base frame 11. An induced draft fan 4 is fixedly connected to the top of each column 12. A spray humidification system 2 is provided on the inner walls of the left and right sides of the columns 12. The spray humidification system 2 includes a control valve 21, which is connected to a high-pressure hose 22. The control valve 21 and the high-pressure hose 22 are located outside the housing 1. The high-pressure hose 22 is connected to a spray water supply pipe 23, which is vertically connected to a spray distribution pipe. 24. The spray distribution pipe 24 is installed parallel to the column 12 on one side of the housing 1. Multiple spray branch pipes 25 are vertically connected to one side of the spray distribution pipe 24. The spray branch pipes 25 are evenly distributed on the inner wall of one side of the column 12. Multiple downward-sloping high-pressure nozzles 26 are provided inside the spray branch pipes 25. Two spray humidification systems 2 are respectively installed on the inner walls of the left and right sides of the column 12. The spray branch pipes 25 and high-pressure nozzles 26 of the two spray humidification systems 2 are fixed to the inner wall of the column 12 in a staggered arrangement. The left and right sides of the column 12... The outer wall of the frame is equipped with anti-freeze louvers 3. The top of the column 12 is equipped with an exhaust fan 4. An air cooler support 5 is installed at the bottom center of the upper surface of the bottom frame 11. Fixed platforms are installed on both sides of the upper surface of the air cooler support 5 at an angle corresponding to the angle of the air cooler 7. An inspection walkway 6 is provided at the center of the upper surface of the air cooler support 5. There are two air coolers 7 arranged in a V-shape inside the housing 1. The bottom of the air coolers 7 is located on both sides of the upper surface of the air cooler support 5, and the top of the air coolers 7 is connected to the inner walls of the left and right sides of the housing 1. At the top, the air cooler 7 divides the housing 1 into a first chamber 13, a second chamber 14, and a third chamber 15. The first chamber 13 and the second chamber 14 are located between the air cooler 7 and the column 12, respectively. The third chamber 15 is located between the upper part of the two air coolers 7 and the induced draft fan 4. A water collection tray 8 is installed at the projection of the air cooler 7, and the water collection tray 8 is fixedly installed at the bottom of the housing 1. The control valve 21 and the anti-freeze louver 3 are both electrically controlled. The anti-freeze louver 3 is made of galvanized sheet. The spray humidification system 2 is connected to the intelligent control system.

[0024] In this type of spray-humidification skid-mounted air cooler, the anti-freeze louvers 3 remain open when the equipment is cooling or the ambient temperature is too high. When the ambient temperature is too high or the equipment load is too heavy, one or more spray humidification systems 2 can be activated as needed. Control valve 21 opens, and demineralized water is pumped to the spray water inlet pipe 23 via a high-pressure pump. After passing through the spray distribution pipe 24 and spray branch pipes 25, the water is atomized into small droplets by the high-pressure nozzles 26, increasing the ambient air humidity and lowering the dry-bulb temperature. After the spray humidification system 2 is activated, the atomized droplets will inevitably splash onto non-heat exchange components such as the air cooler 7's support. Over time, the droplets will fall back to the water collection tray 8 under gravity, facilitating water collection. Centralized recycling and processing; under the action of the induced draft fan 4, the ambient air first passes through the anti-freeze louvers 3 and enters the first chamber 13 and the second chamber 14 respectively, then passes through the air cooler 7 for heat exchange and enters the third chamber 15, and is finally discharged into the atmosphere by the induced draft fan 4; when the equipment has no cooling task, the anti-freeze louvers 3 are closed, the induced draft fan 4 will not generate suction, and the equipment enters the anti-freeze state; through the spray humidification system 2 connected to the intelligent control system, the staff can monitor the ambient temperature, medium, fan and other parameters in real time. The staff can set the parameters in advance on the intelligent control system, so that the intelligent control system can automatically adjust the spray volume and spray time of the spray humidification system 2 according to the changes in parameters, and remotely control the spray humidification system 2 through the intelligent control system.

[0025] This invention elevates the air cooler 7 to a certain height using a support for the air cooler 7, effectively reducing the dead zone of ambient airflow and improving the heat exchange efficiency of the air cooler 7. The spray humidification system 2 adopts a multi-branch spray distribution arrangement to provide an appropriate spray volume as needed, avoiding water waste and the risk of fan shutdown due to excessive spray volume. The spray branch pipes 25 and high-pressure nozzles 26 are arranged in a staggered manner, resulting in more uniform spraying. The high-pressure hose 22 is designed to prevent pipeline vibration from negatively impacting the equipment. The high-pressure nozzles 26 are installed at a downward angle, utilizing the initial kinetic energy of the small droplets sprayed from the high-pressure nozzles 26 to make the trajectory of the small droplets in the first chamber 13 and the second chamber 14 curved, forming a crossflow with the ambient airflow, thereby extending the space and time for air humidification and cooling, and improving the efficiency of humidification and cooling.
