Problems solved by technology

[0002] Existing high-temperature equipment (various high-temperature boilers and high-temperature heating furnaces, high-temperature heating furnaces including resistance heating furnaces and induction heating furnaces, etc.) generally use circulating cooling water as the cooling medium. The advantage of water as the cooling medium is that it is cheap, and its disadvantages Mainly include: (1) Water will corrode equipment materials, especially corrosion will easily cause tiny perforations. Once the cooling cavity is perforated, the cooling water will leak and enter the high temperature room, which will easily cause explosion or other accidents.
The use of chemical preservatives or physical anti-corrosion equipment can slow down corrosion to a certain extent, but it cannot completely eliminate corrosion
(2) It is necessary to build a cold water pool and a hot water pool with a large area, and install a cooling tower with a large volume

Embodiment 1

[0023] Such as figure 1 As shown, the heat carrier oil cooling system includes: an oil storage tank 3, an oil pump 4, a heat exchange system 2, a pipeline system and a measurement control system, which are connected to the high temperature equipment 1 through the pipeline system. A certain volume of heat carrier oil is stored in the oil storage tank 3 as a cooling medium. The heat carrier oil in the storage tank 3 is transported to the high-temperature equipment 1 through the oil pump 4, and the excess heat generated in the high-temperature equipment 1 is taken away. Set up two oil pumps, once one of the oil pumps fails, the other will start running immediately. The heat carrier oil flowing out from the cooling system of the high-temperature equipment enters the heat exchange system 2. The heat exchange system 2 consists of two parts, one is a heat exchanger and the other is a cooler. The heat exchanger adopts stainless steel tube heat exchanger. The cooler uses a centrifug...

Embodiment 2

[0028] Others are the same as in Embodiment 1, except that the heat exchanger adopts a copper tube heat exchanger. The cooler uses industrial air-conditioning, and the air-conditioning refrigeration takes away the heat of the hot oil in the tubes to cool down the hot oil. The conveying pipeline is a plastic oil pipe widely used in industry.

[0029] The high-temperature equipment is a resistance heating furnace with a power of 15kw. It is required that the temperature of the outer surface of the furnace wall is not higher than 30°C when working, and the heat that needs to be taken away from the furnace wall when maintaining the temperature of the outer surface of the induction heating furnace wall is not higher than 30°C is 1.5kw, and the flow rate of heat carrier oil is 35L / min. The heat exchange system is an industrial air conditioner with a power of 2kw. It runs for 24 hours after starting up. The average surface temperature of the induction heating furnace is measured at ...

Abstract

The invention relates to an oil cooling system for high-temperature equipment, which comprises a storage tank, an oil pump, a heat exchange system, a connecting pipeline and a measurement control system, wherein a cooling medium is heat carrier oil; the heat carrier oil heat exchange system is a tubearray heat exchanger; one inlet of the tubearray heat exchanger is connected with a fan or an air conditioner; the other inlet of the tubearray heat exchanger is connected with the heat carrier oil getting hot; and low-temperature heat carrier oil flowing out from a tubearray enters the storage tank. The heat carrier oil (GB / T4016-83) used in the system is also named heat-transfer oil, heat-conduction oil or hot kerosene and the like, and is a heat transfer medium; the heat carrier oil has the advantages of uniform heating, accurate temperature regulation and temperature control, capability of absorbing heat and generating high temperature under low vapor pressure, good heat transfer effect, energy saving, convenient delivery and operation and the like; and the system saves a water treatment system and water treatment equipment, improves the cooling efficiency of the system, reduces the maintenance work load of the equipment and pipelines, and has higher safety and reliability.

Description

technical field [0001] The invention relates to an oil cooling system for high-temperature equipment, which is a cooling system using "heat carrier oil" as a cooling medium.
