Problems solved by technology

[0006] Purpose of the invention: the purpose of the present invention is to solve the problem that the existing cooling tower pipe network design is limited to the structure of the existing pipe network. The flow cannot be balanced, and the overall operating efficiency of the system becomes lower, which ultimately affects the quality of the produced product

Embodiment

[0074] Assume that there are three rectification tower units A, B and C respectively, the height of unit A is 40 meters, and the flow requirement is 1000m 3 / h; the height of device B is 45 meters, and the flow requirement is 1200m 3 / h; the height of device C is 48 meters, and the flow requirement is 1500m 3 / h; how to design cooling water flow balance.

[0075] Implementation step 1: Set up 3 longitudinal pipelines with the same journey, the height of which shall not be less than 48 meters.

[0076] Implementation step 2: Set electric regulating valves V1 on the three longitudinal pipelines on the same journey.

[0077] Implementation step 3: Install the inlet water pressure sensor Pi and the inlet water temperature sensor Ti on the three rectification tower devices respectively, and set the outlet water pressure sensor Po and the outlet water temperature sensor To at the outlet of the rectification tower.

[0078] Implementation step 4: Install an industrial hydraulic ba...

Abstract

The invention discloses an industrial flow balancing system which comprises cooling towers, water circulating pumps, an industrial hydraulic balancing device, rectifying towers, electric control valves, longitudinal equivalent pass pipes, pressure sensors P and temperature sensors T. The system can equalize a flow of an industrial circulating system when the quantity of rectifying tower devices isgreater than one. The invention further discloses a matching method of the industrial flow balancing system. The method adopts a longitudinal equivalent pass structure; pipe diameters of an equivalent pass pipe network are calculated by a calculation formula; and an actual flow requirement is determined. Openings of the electric control valves are adjusted and controlled in real time according toa flow balancing situation of the rectifying tower devices and a current operating load; and the system completely solves the problems of high system redundancy, high system energy consumption, highenergy loss, low product quality and the like caused by the unbalanced industrial cooling water flow.

Description

technical field [0001] The invention relates to an industrial circulating water system, in particular to an industrial flow equalization system and a matching method applied to the case of more than one rectification tower. technical background [0002] In the operation of the industrial cooling water system, whether the cooling water flow is balanced or not determines the output and quality of the product to a large extent. Therefore, improving the flow uniformity of the distillation tower is also the research focus of the entire industrial cooling water technology. Almost all systems pass through a simple pipe network. Towards, manual valves adjust the flow demand, but the hydraulic balance between the cooling terminals cannot be guaranteed only through the manual valves, and the water volume cannot be reasonably transported and distributed according to the terminal needs, which has become a common problem in the industry. [0003] The existing technology generally uses se...
