Description

Technical Field

[0001] This utility model belongs to the field of air separation equipment technology, specifically relating to an energy-saving circulation pipeline that reduces the power consumption of oxygen-generating water pump rooms. Background Technology

[0002] The main function of the air separation circulating water system is to ensure that the cooling water circulates continuously according to the required flow rate of the heat exchange equipment in order to ensure the normal operation of the equipment. The power consumption mainly comes from the circulating water pump, which has a very serious power consumption, accounting for 90% of the total power consumption of the circulating water system.

[0003] Currently, oxygen production pump stations typically use conventional fixed-head pumps for circulating water supply. Fixed-head pumps are usually set at a high head, resulting in excessive energy consumption to maintain water flow during operation. This excessively high head leads to significant unnecessary energy consumption and waste of energy resources. Increased energy consumption directly raises the operating costs of oxygen production, impacting the company's economic efficiency and competitiveness. Prolonged operation at excessively high heads accelerates pump component wear and aging, shortening equipment lifespan. This not only increases maintenance and replacement costs but may also affect the overall system's stability and reliability.

[0004] Therefore, how to effectively reduce the power consumption of oxygen-generating water pump rooms and improve the operating efficiency of equipment has become an important issue that urgently needs to be addressed. Thus, an energy-saving circulation pipeline for reducing the power consumption of oxygen-generating water pump rooms is proposed. Utility Model Content

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figure 1 As shown, an energy-saving circulating pipeline for reducing power consumption in an oxygen-generating water pump room includes a water tank 1. The water tank 1 serves as the water storage center for the entire circulating water system, responsible for storing the cooling water required for circulation and connecting to other components. The water tank 1 can effectively regulate the water volume and maintain the water temperature, providing a stable water source.

[0023] The water tank 1 is equipped with a cooling tower fan 2, which is used to lower the water temperature and enhance the heat dissipation effect of the water in the water tank 1. The cooling tower fan 2 lowers the temperature of the cooling water to the required level by driving airflow. The cooling tower fan 2 can effectively improve the cooling efficiency of the water, reduce the water temperature, and thus improve the working efficiency of the heat exchange equipment.

[0024] A water outlet pipe extends from the bottom of water tank 1, connecting to water-using equipment 4. Water-using equipment 4 is a facility requiring cooling water support, typically involving heat exchange equipment or oxygen generation equipment. By obtaining a stable flow of cooling water, water-using equipment 4 ensures its efficient operation, thereby guaranteeing the stability and continuity of the production process. A circulating water pump 3 is installed at the front end of the outlet pipe. Circulating water pump 3 is responsible for pumping cooling water from water tank 1 to water-using equipment 4, ensuring the continuity of water flow. An electric outlet valve 5 is installed behind circulating water pump 3. Located behind circulating water pump 3, electric outlet valve 5 controls the water flow to water-using equipment 4. By adjusting the water flow, electric outlet valve 5 ensures that circulating water pump 3 operates under suitable working conditions, reducing unnecessary energy consumption and helping to optimize pump efficiency.

[0025] Water-using equipment 4 is connected to water tank 1 through a return water pipe. A return water valve 6 is installed at the end of the return water pipe. The return water valve 6 is located at the end of the return water pipe and is responsible for controlling the flow rate of cooling water flowing from water-using equipment 4 back to water tank 1.

[0026] The specific design of the aforementioned key components will be discussed in detail below:

[0027] It also includes a cooling tower, which is connected to the water-using equipment 4 and the water tank 1 via a return water pipe. The cooling tower, positioned between the water-using equipment 4 and the water tank 1, cools the circulating water before it enters the water tank 1. The cooling tower is designed to maximize water flow efficiency and optimize airflow path, typically using packing material to increase the contact area between water and air, thereby improving heat exchange efficiency. The cooling tower effectively lowers the water temperature, thus helping to improve the heat exchange efficiency of the water-using equipment 4 and reduce energy consumption.

[0028] Several cooling tower fans 2 are installed inside the water tank 1. The number of cooling tower fans 2 is selected based on the size of the water tank 1 and the cooling requirements. The air volume and air speed of the cooling tower fans 2 are adjustable to adapt to different temperature conditions and load requirements.

[0029] The number of circulating water pumps 3 is several, and multiple circulating water pumps 3 are connected in parallel. The parallel connection allows one or more circulating water pumps 3 to be activated individually as needed, thereby reducing power consumption and extending the service life of the equipment. It also allows the use of circulating water pumps 3 with smaller heads when the load is low, thus reducing energy consumption.

[0030] A network pressure gauge 7 is installed on the outlet pipe. The network pressure gauge 7 can monitor the internal pressure of the outlet pipe in real time, which helps operators monitor the pressure of the water pipe system, adjust the operating status of the circulating water pump 3 in a timely manner, or troubleshoot faults, so as to achieve safe and efficient operation.

[0031] The return water pipe is divided into multiple connection ports at different locations in the water tank 1, and the number of return water valves 6 corresponds to the number of connection ports. The multiple connection ports at the end of the return water pipe ensure uniform water return distribution. Each return water valve 6 controls its corresponding return water flow rate, improving the water circulation efficiency within the water tank 1, optimizing the water flow path, and effectively regulating the flow rate.

[0032] The number of circulating water pumps 3 is 4, with 2 pumps having a head of 28 meters and 2 pumps having a head of 42 meters, in order to meet the flow requirements under different working conditions.

[0033] The number of electric outlet valves 5 corresponds to the number of circulating water pumps 3, and the circulating water pumps 3 are connected in series with the electric outlet valves 5. The number of electric outlet valves 5 matches the number of circulating water pumps 3, with one electric outlet valve 5 connected in series behind each circulating water pump 3 to control the water flow output from this circulating water pump 3 to the water-using equipment 4. The electric outlet valves 5 can precisely adjust the flow rate to meet the needs of different operating conditions, ensuring a balance between operating efficiency and safety, while reducing unnecessary power consumption.

[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
