Description

Technical Field

[0001] The utility model relates to the field of chemical equipment structures, in particular to a high-temperature heat transfer oil cooling system for a workshop. Background Art

[0002] In the field of chemical equipment, especially in the production process of insulating resin polyester reactors, the heat transfer oil cooling technology is a common equipment cooling method. This technology mainly cools through a heat transfer oil condenser to control the temperature of the reactor. In this process, the heat transfer oil condenser plays a key role. It takes away the heat of the heat transfer oil through circulating water, thereby reducing the temperature of the heat transfer oil.

[0003] In the existing technology, usually two series-connected heat transfer oil condensers are used to cool the high-temperature heat transfer oil, reducing the high-temperature heat transfer oil from 290 degrees Celsius to about 60 degrees Celsius. The temperature difference fluctuates greatly, which easily causes damage to the welds between the heat transfer oil pipes and the reactor, resulting in leakage of the high-temperature heat transfer oil. The high-temperature heat transfer oil can ignite the insulation layer of the reactor, thus causing safety production accidents. Secondly, when the heat transfer oil condenser cools the heat transfer oil at 290 degrees Celsius, the circulating water will violently vaporize, causing a sharp increase in the internal pressure of the condenser, resulting in leakage of the condenser seal. These problems seriously affect the safety and efficiency of production and also increase the equipment maintenance cost. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a high-temperature heat transfer oil cooling system for a workshop, which solves the problems of poor safety, low stability, low efficiency in the production process of polyester insulating resin in the prior art, high equipment overhaul and maintenance costs, and environmental pollution caused by leakage of high-temperature heat transfer oil.

[0008] The two heat transfer oil condensers include a first heat transfer oil condenser and a second heat transfer oil condenser, and both the first heat transfer oil condenser and the second heat transfer oil condenser are connected to a circulating water system;

[0009] The high-temperature heat transfer oil inlet of the first heat transfer oil condenser is connected to the outlet of the heat transfer oil coil.

The automatic control valve on the second pipeline with an automatic control valve is interlocked with the temperature at the outlet of the transfer pump. The transfer pump is used to transport the heat transfer oil into the heat transfer oil coil of the reaction kettle.

[0012] Further, a sealing device is installed at the tail end of the semi-closed heat exchange tube, and the sealing device is sealed by a gasket.

[0019] As Figure 1 shown, a high-temperature heat transfer oil cooling system for a workshop includes a reaction kettle 1, two heat transfer oil condensers 2, a transfer pump 3, and a collection tank 4;

[0020] The reaction kettle 1 is internally provided with a stirring paddle. A first temperature sensor is provided on the inner wall of the reaction kettle 1, and a heat transfer oil coil 7 is welded to the outer wall of the reaction kettle 1;

[0021] The two heat transfer oil condensers 2 have the same structure and are both water-cooled heat exchangers. Water-cooled heat exchangers have been widely used in many fields such as industrial production, construction, and agriculture due to their advantages of high-efficiency cooling and heating capabilities, energy conservation and environmental protection, economy, compact structure and easy maintenance, as well as flexibility and reliability.

[0022] The heat transfer oil condenser 2 is provided with a high-temperature heat transfer oil inlet, and a semi-closed heat exchange tube is provided near the high-temperature heat transfer oil inlet on the heat transfer oil condenser 2. A sealing device is also installed at the tail end of the semi-closed heat exchange tube, and the sealing device is sealed through a gasket.

[0023] A pressure sensor and an automatic control valve are also interlocked on the heat transfer oil condenser 2;

[0024] The two heat transfer oil condensers 2 include a first heat transfer oil condenser 21 and a second heat transfer oil condenser 22, and both the first heat transfer oil condenser 21 and the second heat transfer oil condenser 22 are connected to a circulating water system;

[0025] The second heat transfer oil condenser 22 can be used to assist in realizing the secondary cooling of the high-temperature heat transfer oil.

[0026] The circulating water system includes a water storage tank. The outlet of the water storage tank is connected to the water inlets of the first heat transfer oil condenser 21 and the second heat transfer oil condenser 22 through a first three-way pipe 5, and the inlet of the water storage tank is connected to the water outlets of the first heat transfer oil condenser 21 and the second heat transfer oil condenser 22 through a second three-way pipe 6.

[0027] The high-temperature heat transfer oil inlet of the first heat transfer oil condenser 21 is connected to the outlet of the heat transfer oil coil 7. The heat transfer oil outlet of the first heat transfer oil condenser 21 is provided with two sections of pipelines with automatic control valves. The first section of the pipeline with an automatic control valve is connected to the transfer pump 3, and the second section of the pipeline with an automatic control valve is connected to the high-temperature heat transfer oil inlet of the second heat transfer oil condenser 22;

[0028] A second temperature sensor is installed at the outlet of the transfer pump 3. The automatic control valve on the second section of the pipeline with an automatic control valve is interlocked with the temperature at the outlet of the transfer pump 3. A fuel delivery pipeline is connected between the transfer pump 3 and the inlet of the heat transfer oil coil 7 for delivering the heat transfer oil to the heat transfer oil coil 7 in the reaction kettle 1.

[0029] The collection tank 4 is connected to the pressure relief ports of the two heat transfer oil condensers 2 for receiving the water vapor released by the pressure relief of the heat transfer oil condensers 2.

[0030] In this utility model, the high-temperature heat-conducting oil is cooled by the heat-conducting oil condenser 2. The high pressure generated by the violent gasification of the circulating water in the first and second heat-conducting oil condensers 2 is automatically released through the pressure relief port. The temperature of the heat-conducting oil is interlocked and controlled by the automatic control valve. The transfer pump 3 transports the heat-conducting oil at the required temperature to the heat-conducting oil coil 7 in the reaction kettle 1. This can reduce the equipment damage and maintenance costs, and at the same time reduce the safety hazards brought by the leakage of high-temperature heat-conducting oil.

[0031] The working principle of this patent:

[0032] When the high-temperature heat-conducting oil enters the first heat-conducting oil condenser 21, the circulating water circulating between the circulation system and the two heat-conducting oil condensers 2 violently gasifies, the pressure rises, the seal of the semi-closed heat exchange tube automatically closes, and the pressure is automatically released through the pressure relief port. The temperature of the heat-conducting oil is automatically interlocked and controlled by the automatic control valve. Then, if the oil temperature reaches the standard, it is transported to the heat-conducting oil coil 7 in the reaction kettle 1 by the transfer pump 3 to cool the materials in the kettle. If the oil temperature does not reach the standard, it is sent to the second heat-conducting oil condenser 22 through the second pipeline with an automatic control valve for secondary cooling. After the oil temperature reaches the standard, it is transported to the heat-conducting oil coil 7 in the reaction kettle 1 by the transfer pump 3 to cool the materials in the kettle.
