Description

Technical Field

[0001] This invention belongs to the field of chemical equipment technology, specifically a cooling tower with defogging function. Background Technology

[0002] The most widely used cooling tower in petrochemical enterprises is the mechanical ventilation wet cooling tower. During operation, this tower experiences water evaporation loss, resulting in water waste; it also forms plumes, which not only reduce visibility on surrounding roads and accelerate equipment corrosion, but also make surrounding roads slippery, posing safety hazards for workers conducting inspections. Therefore, reducing evaporation loss and eliminating plumes from cooling towers is extremely important.

[0003] Patent application number 202310393600.8 discloses a fog-reducing and water-saving cooling tower, comprising: a spray pipe, a heat exchange chamber disposed below it, a condensation chamber disposed above the spray pipe, packing material disposed within the heat exchange chamber, a water collection pool disposed below the packing material, and multiple air inlets disposed within the heat exchange chamber and the condensation chamber; the cooling tower further comprises: a cooling box; a flow guiding component; and a conversion component; the condensed airflow is sent into the flow guiding component through the ventilation pipe, and some of the water droplets formed after condensation fall directly into the cooling box, while the remaining water droplets rise to the top plate of the flow guiding component and are guided to flow towards the cooling box. At the same time, the direction of the humid and hot airflow is guided in the same direction as the water droplet flow, which can push the water droplets towards the cooling box while outputting humid and hot air, avoiding the problem that the humid and hot airflow and the condensed water droplet flow are in conflict, causing the water droplets to be impacted and scattered, resulting in the water droplets coming into contact with the humid and hot airflow again and thus reducing the condensation efficiency of the humid and hot air, thereby achieving the fog-reducing and water-saving effect.

[0004] However, the aforementioned equipment has a relatively complex structure, and in practical applications, it suffers from many problems such as high production costs and inconvenient installation. The applicant has focused on the research of cooling towers for many years, and after many improvements and studies, has finally developed a cooling tower with a simple structure, good heat exchange effect, and the ability to eliminate fog. The entire equipment has a novel structure and has achieved a major technological breakthrough in practical applications, making a significant contribution to environmental protection and energy conservation. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a cooling tower with anti-fogging function, thereby solving the problems mentioned in the background section. The technical solution adopted is as follows:

[0006] A cooling tower with defogging function includes: a tower body, and an air outlet at the top of the tower body for discharging hot air.

[0007] An air outlet is provided, and a fan is installed inside the air outlet. The fan is connected to a drive motor via a drive shaft. The drive motor is used to drive the fan to work and is installed on one side of the air outlet. The fan drives the hot air to rise rapidly to form a heat exchange.

[0008] The water inlet pipe is connected to the spray pipe. The water inlet pipe contains industrial hot water, which is cooled and then recycled.

[0009] The spray pipe has a set of evenly arranged spray heads. The top of the spray pipe is a condensation chamber and the bottom of the spray pipe is a heat exchange chamber. The condensation chamber is used to cool the hot and humid air, and the heat exchange chamber is used to fully exchange heat between the cooled air and the hot water. The packing layer is located below the spray heads. The water collection chamber is located at the bottom of the tower.

[0010] The bottom air inlet is located at the bottom of the tower body and above the water collection chamber. The water outlet is connected to the water collection chamber. The above structure is the structure of an existing cooling tower. The specific functions and roles of each component will not be elaborated here.

[0011] The core improvements of this invention are as follows:

[0012] It also includes a water collection tank a, which is used to collect condensate. The water collection tank a is installed in the condensation chamber and connected to the inner wall of the tower. The upper part of the water collection tank a is open, and the lower part of the water collection tank a is connected to a water pipe. The water pipe is connected to the water collection chamber. A set of inclined hot air pipes is installed on the water collection tank a. The hot air pipes are inclined towards the middle and become higher towards the center of the water collection tank a.

[0013] The cold air duct is designed symmetrically with the hot air duct, with the upper part of the cold air duct extending to the upper part of the tower and the lower part extending to the water collection tank a to form a complete heat exchange system. The working principle of the above structure is as follows:

[0014] After heat exchange, the humid and hot air enters through the hot air duct and comes into contact with the cold air entering through the cold air duct, directly forming a heat exchange. Due to the symmetrical design, the heat exchange effect is optimal at this time. After heat exchange, the water in the humid and hot air condenses and continues to slide down from the cold air duct into the water collection tank a and then falls into the water collection chamber through the water pipe. The above structural design can completely improve the heat exchange efficiency.

[0015] Preferably, in order to better reduce production and installation costs, water collection tank b is used instead of water collection tank a. Water collection tank b is fixedly installed on the inner wall of the tower body by a circular baffle. The upper part of water collection tank b is open. A set of inclined hot air pipes is set on the circular baffle. The hot air pipes are inclined towards the middle and become higher towards the center of water collection tank b.

[0016] The cold air duct is designed symmetrically with the hot air duct, with the upper part of the cold air duct extending to the upper part of the tower and the lower part extending to the water collection tank b to form a complete heat exchange system. Through the improvement of the water collection tank structure, the entire water collection tank structure becomes more compact, the production and installation costs are further reduced, and the problem of low heat exchange rate can be solved. In order to better collect water, the water collection tank b is designed with an inverted cone shape.

[0017] Preferably, in order to better recycle water resources and reduce the evaporation rate, a condensate collector is installed near the water collection tank b in the cold air duct. The condensate collector is used to collect the water after heat exchange and make it fall quickly to prevent it from being evaporated and carried away by the hot and humid air. The condensate collector is equipped with a movable condensate collection component, which includes a cylinder and several tree-shaped condensate collection rods installed in the outer cylinder. The above structure utilizes biomimetic technology and can better collect condensate.

[0018] Preferably, in order to better recycle water resources, the condensate collection component is divided into two sections, namely condensate collection component a and condensate collection component b. A tapping vibration device is set between condensate collection component a and condensate collection component b. The tapping vibration device continuously taps the pipe, so that the water on the tree-shaped condensate collector can fall quickly and be collected.

[0019] The striking vibration device is one of the core components of this invention. The striking vibration device includes a sleeve, with fixing members at both the top and bottom of the sleeve. A rotating shaft is movably connected to the middle of the fixing members via a bearing. The rotating shaft has at least one rotating blade and a telescopic rod. A roller is provided on the telescopic rod. The roller is a rubber wheel. At least one protrusion is provided on the inner wall of the sleeve where the roller rotates. The roller contacts the protrusion to form a striking process. The number of telescopic rods and protrusions is at least 2.

[0020] Preferably, in order to achieve a better striking effect, the rotating blades are designed as an upper and lower set, and the telescopic rod is located in the middle of the rotating blades.

[0021] Preferably, the number of cold air ducts is at least 2. The number of cold air ducts can be adjusted as needed according to the heat exchange requirements, and can be 2, 3, 4...N.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] Through the structural modification of this invention, heat exchange is achieved by directly blowing cold air and hot air into each other. After heat exchange, the condensed water droplets fall from the cold air duct into the water collection tank and then from the water pipe into the water collection chamber. The above structural design is simpler and more reasonable. This structure can completely solve the problem of poor condensation efficiency caused by the collision between the hot and humid air flow and the condensed water droplets. Through the above structural design, water evaporation is reduced due to better condensation, thereby reducing the generation of plumes and improving environmental protection. It fully meets the national environmental protection requirements and plays a positive role in the chemical production industry, especially the PTA industry. It is suitable for widespread promotion and application. Attached Figure Description

The humid air, after heat exchange, enters from the hot air pipe 11 and comes into contact with the cold air entering from the cold air pipe 12, directly forming heat exchange. Due to the symmetrical design, the heat exchange effect is optimal at this time. Because of the added function of the condensate collector 16, more condensate will be collected, further reducing water evaporation, thus achieving energy saving and environmental protection. The aforementioned equipment incorporates a striking vibration device 18. The hot air after heat exchange drives the rotating blades 18-7 to rotate, which in turn drives the rotating shaft 18-3. The rotating shaft 18-3 then drives the telescopic rod 18-4 to rotate, which in turn drives the roller 18-5. During rotation, the roller 18-5 contacts the protrusion 18-6. The telescopic rod then extends, continuously contacting the sleeve 18-1 during this extension, creating a striking effect that quickly knocks down and condenses the condensate. The condensate then flows down the cold air duct into the water collection tank b15 and then down the water pipe 13 into the water collection chamber 8. This structural design significantly improves heat exchange efficiency, reduces water evaporation, and thus reduces plume formation, offering both environmental protection and energy-saving benefits. Furthermore, the structure is more rational, easier to install, and lower in cost.
