Abstract

The invention discloses a method for measuring the outlet water temperature distribution of a power tower without a wind-shielding wall in a falling area, comprising the steps of: a. Fixing two steel wire ropes at both ends between the edge columns on opposite sides of the power tower, and the steel wire ropes are parallel to the ground , the height from the ground is H; b. Install a number of slip rings made of stainless steel wires welded at both ends at equal intervals on the steel wire rope, and the diameter of the steel wire is D 2 , the total number of slip rings is M, and the distance between two adjacent slip rings is L; c. Pass the rope through the slip ring and knot the two ends of the rope into a closed loop, the rope material is nylon rope, and the diameter is D 3 , the length of a single rope is L 1 , put the rope through the slip ring and then knot it; d. Arrange U waterproof wireless platinum resistance resistors continuously on the rope on one side, pull the other side rope in the opposite direction of the slip ring, move the platinum resistance resistance to the measurement area and arrange it evenly, Fix one end of the rope on the steel wire rope; e. Debug the wireless platinum resistance signal receiving device and data acquisition software, and then real-time and continuous measurement of the water temperature distribution of the power tower can be carried out.

Description

technical field [0001] The invention belongs to the field of measuring the outlet water temperature distribution of a power tower, and particularly relates to a method for measuring the outlet water temperature distribution of a power tower without a wind-shielding wall in a falling area. Background technique [0002] Mechanical ventilation cooling towers are usually arranged in groups or side by side. Accurate cooling tower outlet water temperature must be obtained if the thermal performance of a cooling tower unit needs to be studied, especially when the detailed aerodynamic distribution of the cooling tower fill, water eliminators, sprinkler heads, and the entire cooling tower needs to be analyzed. The temperature distribution of the falling water in the tower is a very important thermal parameter, which directly reflects the performance of the cooling tower. [0003] To measure the temperature distribution of the falling water of the mechanical tower, the existing techn...

Problems solved by technology

[0003] To measure the temperature distribution of the falling water of the mechanical tower, the existing technology mainly adopts the means of centralized collection and unified measurement of the cooling tower falling water through the water collector. The falling water in the water collector is uniformly collected into the temperature measuring container for measurement. Since it is very difficult to arrange the water collecting device in the water falling space of the cooling tower, this method is difficult to implement in practice

[0004] In addition to using the water collector to measure the temperature distribution of the water falling into the power tower, it is also currently used to fix the thermocouple on the swimming ring and drag it in the pool to measure the water temperature distribution, but obviously this method The temperature distribution data of the water tower falling water at the same time cannot be obtained, and the coordinate positioning of the measurement data is not accurate

Therefore, the method is less accurate in practice
