Water tank temperature-controllable air-cooled high-temperature heat exchange system and application method thereof

Abstract

The invention discloses a water tank temperature-controllable air-cooled high-temperature heat exchange system. The water tank temperature-controllable air-cooled high-temperature heat exchange systemcomprises a high-temperature circulation fluid system and a refrigeration circulation system. A water-tank cooling heat exchanger is additionally arranged in a water tank of the high-temperature circulation fluid system, refrigeration circulation is realized through the heat exchanger to perform cooling on circulation fluid supplement liquid in the water tank to control the temperature of the water tank, the impact of the thermal expansion and contraction of circulation liquid in the water tank on the circulation system is reduced, the phenomenon that overflowing is caused due to the fact that the circulation liquid in the water tank is too much or shut down is caused due to the fact that the circulation liquid in the water tank is too little is avoided, and meanwhile, the risk of scalding to the operator is reduced. The invention further discloses an application method of the high-temperature heat exchange system.

Description

technical field [0001] The invention relates to a high-temperature heat exchange system, in particular to an air-cooled high-temperature heat exchange system with controllable temperature of a water tank and a use method thereof. Background technique [0002] For high-temperature heat exchange equipment with a wide temperature range, the temperature of the circulating fluid rises after absorbing heat energy, and the volume of the circulating fluid expands, while the liquid circulation system is a closed circuit. If there is no suitable constant pressure replenishment tank, the circulating medium will contain gas , affects the flow rate of the circulation loop, and at the same time, with the expansion of the volume, the pressure in the pipe will also increase. On the contrary, when the temperature is lowered, the volume of the liquid becomes smaller, and a negative pressure is also generated in the pipe, which will also have an adverse effect on the flow rate and pressure.

Problems solved by technology

[0003] For high-temperature heat exchange equipment, due to the influence of heat transfer, the temperature of the circulating fluid replenishment liquid in the water tank will also rise. Affected by thermal expansion and contraction, the circulating fluid level in the water tank will also change in a wide range, which is likely to cause overheating. The phenomenon of full overflow or too little shutdown will seriously reduce the performance of the water tank. At the same time, if the temperature of the water tank is too high, there is a risk of being scalded by the operator during the process of adding circulating fluid and inspection and maintenance.
