Problems solved by technology

The temperature measurement of the existing salt tank is multi-point temperature measurement of the tank body, mainly to measure the temperature of the salt, which cannot reflect the insulation performance of the salt tank
In addition, manual measurement of salt tanks with infrared handheld temperature measuring guns on a regular basis cannot reflect the heat dissipation of tanks effectively in real time

Abstract

The invention provides a temperature monitoring system for a heat storage tank of a trough type photo-thermal power station, which comprises the heat storage tank, a first temperature sensor and a plurality of second temperature sensors, and is characterized in that the first temperature sensor is arranged right above the heat storage tank and is used for monitoring the temperature of each subarea at the top of the heat storage tank; the plurality of second temperature sensors are uniformly distributed around the tank body of the heat storage tank and are used for monitoring the temperature of each subarea of the tank body of the heat storage tank, and the second temperature sensors are in one-to-one correspondence with the subareas of the tank body. According to the technical scheme, the heat preservation performance of the heat storage tank and the heat dissipation loss of the tank body can be monitored in real time, the structure is simple, and cost is low.

Description

technical field [0001] The invention relates to the technical field of photothermal power plants, in particular to a temperature monitoring system for a heat storage tank of a trough-type photothermal power station. Background technique [0002] At present, the heat storage medium of trough-type and tower-type photothermal power plants is made of potassium salt and sodium salt mixed in a certain proportion. Generally, solar thermal power plants are equipped with two cylindrical salt tanks, cold and hot, with a diameter of about 40 meters and a height of about 14 meters. The insulation material of the cylindrical salt tank is generally made of aluminum silicate, and the thickness of the tank body is about 40 cm, and the outer layer is wrapped with aluminum skin. With the increase of the operation time of the system and the leakage of rain on the top of the tank, the thermal insulation performance will gradually deteriorate, and the heat dissipation loss of the salt tank will...
