Abstract
Description
Technical Field
[0001] The utility model relates to the field of white oil tank cooling, in particular to an air-cooled white oil tank for a pump in chemical production. Background Art
[0002] In chemical production, white oil tanks are critical equipment, not only ensuring the safe storage of white oil but also shouldering the crucial responsibility of maintaining its quality and stability through effective cooling. Currently, to address potential issues with white oil deterioration and accelerated oxidation at high temperatures, a cooling water system is commonly installed. However, while effective, this solution comes with its own challenges and cost considerations.
[0003] First, regarding installation costs, a white oil tank cooling water system requires meticulous design and layout, including the laying of cooling water piping, the selection and installation of cooling towers or heat exchangers, and the configuration of pumps and control systems. These steps require specialized engineering expertise and substantial capital investment. Furthermore, to ensure stable system operation and efficient energy consumption, the use of corrosion-resistant and high-temperature-resistant materials is necessary, further increasing initial investment costs.
[0004] Secondly, the white oil tank cooling water system also faces significant challenges in terms of daily maintenance. Regular water quality testing and treatment, pipeline cleaning and scale prevention, equipment maintenance, and component replacement all require a dedicated team. This not only increases labor costs but can also cause production interruptions and impact overall operational efficiency.
[0005] Furthermore, the energy consumption of circulating water is a significant issue. During the cooling water circulation process, it must be continuously pumped under pressure and may also require cooling towers for heat dissipation. These processes consume significant amounts of electricity. Energy consumption increases significantly during hot weather or under high production loads, placing pressure on a company's operating costs.
[0006] In addition, a large amount of cooling water will be discharged during the maintenance of the cooling water system, and it needs to be replenished immediately after maintenance; and in the daily use of the cooling water system, evaporation and leakage will also occur, so the circulating water needs to be replenished regularly; it can be said that during the use of the cooling water system, the circulating water needs to be continuously consumed, wasting water resources. Utility Model Content
[0007] The purpose of the utility model is to provide an air-cooled white oil tank for a machine pump in chemical production, so as to solve the problems of high installation and commissioning cost and high energy consumption in daily operation of the existing white oil tank cooling system.
[0008] In order to achieve the above purpose, the technical solution of the utility model is:
[0009] The utility model provides an air-cooled white oil tank for a pump in chemical production, comprising an upper tank body, a lower tank body and an air cooler, wherein the top inlet of the air cooler is in sealed communication with the bottom of the upper tank body, and the bottom outlet of the air cooler is in sealed communication with the top of the lower tank body;
[0010] A white oil return port is provided on the top of the side wall of the upper tank body;
[0011] A white oil outlet is provided at the lowest point of the lower tank body, and a temperature transmitter is provided on the side wall of the lower tank body;
[0012] A fan is provided on one side of the air cooler.
[0013] Furthermore, a liquid level gauge is provided on the side wall of the upper tank body.
[0014] Furthermore, a refueling valve is provided on the upper half of the side wall of the upper tank body, one end of the refueling valve is connected to the upper tank body, and the other end is a white oil adding port.
[0015] Furthermore, a pressure gauge and a pressure relief solenoid valve are provided on the top of the upper tank body. One end of the pressure relief solenoid valve is connected to the upper tank body, and the other end is a flare discharge port.
[0016] Furthermore, the air cooler is a fin-tube air cooler or a plate air cooler.
[0017] Furthermore, the air-cooled white oil tank also includes a control module, which includes a PLC controller, several relays, several control buttons and a display screen.
[0018] The beneficial effects achieved by the utility model are:
[0019] This utility model designs a highly efficient and economical white oil cooling system, the core of which is the use of a fin-tube or plate-type air cooler. This system cleverly combines passive and active cooling mechanisms: when the white oil temperature is low, it fully utilizes the natural convection heat dissipation characteristics of the fin structure to achieve passive cooling without energy consumption, effectively saving energy. When the white oil temperature rises above a preset threshold, the built-in fan device is automatically or manually activated, creating an active cooling effect by enhancing air flow, quickly removing heat and ensuring that the white oil temperature remains stable within a safe and efficient operating range.
[0020] This new design features a compact overall structure, eliminating the complex piping layout found in traditional cooling systems. This significantly reduces material and manufacturing costs while also improving space utilization, making installation and deployment more flexible and convenient. Furthermore, its simple structure and lack of delicate components significantly simplify subsequent maintenance, reducing both cost and time, and improving the overall operational efficiency and reliability of the equipment.

[0028] The top of the side wall of the upper tank body 110 is provided with a white oil return port 111;
[0029] A white oil outlet 121 is provided at the lowest point of the lower tank body 120, and a temperature transmitter 122 is provided on the side wall of the lower tank body 120;
[0030] A fan 131 is provided on one side of the air cooler 130 .
[0031] Working principle: Before the air-cooled white oil tank 10 is put into use, the white oil pipeline flow is first opened. Specifically, the white oil return port 111 is connected to the inlet end of the white oil pipeline, and the white oil outlet 121 is connected to the outlet end of the white oil pipeline to form a complete white oil circuit; then the white oil is injected to the normal liquid level. When the machine pump is running, the white oil is circulated from the air-cooled white oil tank 10 to the machine pump. The white oil flows out through the white oil outlet 121 at the lower part of the air-cooled white oil tank 10 and enters the pump body. After heat exchange, the white oil flows from the pump body to the white oil return port 111 and enters the upper tank body 110 of the air-cooled white oil tank 10, and then flows through the air cooler 130 cools the white oil, and the cooled white oil enters the lower tank 120, and then enters the pump body through the white oil outlet 121, so as to be recycled; when the external temperature or the abnormality of the machine pump causes the white oil temperature to rise, when it reaches the interlock value, the temperature transmitter 122 sends a signal to the PLC controller, and the PLC controller sends a signal to the power control relay of the fan 131, the relay coil is energized, the power of the fan 131 is connected, and the fan 131 starts to cool the white oil; when the temperature drops below the interlock value, the temperature transmitter 122 sends a signal to the PLC controller, the relay coil is disconnected, the power of the fan 131 is disconnected, and the fan 131 stops.

[0033] Furthermore, a refueling valve 113a is provided on the upper half of the side wall of the upper tank body 110, one end of the refueling valve 113a is connected to the upper tank body 110, and the other end is connected to the white oil adding port 113; during the maintenance or daily use of the machine pump, the white oil will inevitably be lost, and the staff can replenish the white oil through the white oil adding port 113.
[0034] Furthermore, a pressure gauge 115 and a pressure relief solenoid valve 114a are provided on the top of the upper tank body 110. One end of the pressure relief solenoid valve 114a is connected to the upper tank body 110, and the other end is connected to a flare discharge port 114. The flare discharge port 114 is connected to the flare system in the chemical plant; the pressure gauge 115 detects the pressure information in the air-cooled white oil tank 10 and transmits the pressure information to the PLC controller; in the event of an emergency, such as a sudden pressure rise caused by equipment failure, operational error or external factors, when the threshold is reached, the PLC controller controls the pressure relief solenoid valve 114a to discharge hazardous materials in a timely manner to reduce accident losses and the risk of expansion.
[0035] Furthermore, the air cooler 130 is a fin-tube air cooler or a plate air cooler.
[0036] Furthermore, the air-cooled white oil tank 10 also includes a control module, which includes a PLC controller, several relays, several control buttons and a display screen; the PLC controller is the control center of the present invention, which obtains data through the temperature inverter and pressure gauge 115, and then controls the opening and closing of each solenoid valve and fan 131 through the relay.
