The invention discloses a heating medium expansion tank installation height determination method of a heating medium system and the heating medium system. The heating medium system comprises a heatingmedium circulating pump which comprises a heating medium circulating pump inlet; a heating medium expansion tank comprising a heating medium oil injection port, a heating medium oil exhaust port anda pressurized gas inlet, wherein the heating medium oil exhaust port is communicated with the inlet of the heating medium circulating pump through a pipeline, and the pressurized gas inlet is used forinjecting inert gas into the heating medium expansion tank, so that the gas pressure P in the heating medium expansion tank meets the following conditions: the gas pressure P in the heating medium expansion tank > steam pressure P + Delta P + essential pressure P - P heating medium oil, wherein the steam pressure P is the steam pressure of a heating medium oil medium, the Delta P is the pipelinefriction resistance of the heating medium circulating pump inlet, the essential pressure P is essential net positive suction pressure, and the heating medium oil P is the heating medium oil static pressure between the heating medium expansion tank and the heating medium circulating pump, wherein P heating medium oil is equal to Rho gh, the Rho is the density of the heating medium oil, g is the gravitational acceleration, and h is the height difference between the maximum liquid level height of the heating medium oil in the heating medium expansion tank and the inlet of the heating medium circulating pump. The installation height of the heating medium expansion tank is set according to needs.
Description
technical field [0001] The invention relates to the technical field of heat medium systems, in particular to a method for determining the installation height of a heat medium expansion tank of the heat medium system and the heat medium system. Background technique [0002] Heat medium oil system, including but not limited to providing heat source for crude oil stabilization tower, start-up heat exchanger and vacuum desulfurization tower. In the design of the heat medium system, according to SY / T 0524-2016 "Specification for Heat Transfer Oil Heating Furnace System" 8.1.5, "The vertical clearance between the bottom of the heat medium expansion tank and the highest point of the heat transfer oil system should not be less than 1.5 meters" , The heat medium oil expansion tank will be placed at the highest point of the entire system to provide space for the heat medium oil to expand when heated. This will not only greatly increase the amount of steel structure engineering, great...
