Embodiment

[0029] A cooling tower cooling system based on flow variation, such as figure 1 As shown, the cooling system of the cooling tower is connected with the circulating water of the workshop, including the water inlet pipeline 1, the closed cooling tower group and the water outlet pipeline 2 connected in sequence; the closed cooling tower group includes three closed cooling towers 3 connected in parallel , and the tower water flow ranges corresponding to the high energy efficiency intervals of the three closed cooling towers 3 are different. When in use, according to the size of the water flow to be treated, a matching closed cooling tower is selected for operation; and the fan in the closed cooling tower 3 The frequency of the motor is controlled using the wet bulb temperature. Such as figure 1 As shown by the middle arrow, when the system is working, the water passes through the main water inlet pipeline 11, the water pump 13, the water inlet branch pipeline 12, the closed cooli...

Abstract

The invention relates to a cooling tower cooling system based on flow change. The system is connected with workshop circulating water and comprises a water inlet pipeline, a closed cooling tower set and a water outlet pipeline which are sequentially connected, wherein the closed cooling tower group comprises a plurality of closed cooling towers connected in parallel, and the tower water flow ranges corresponding to the high-energy-efficiency intervals of the plurality of closed cooling towers are different; the water inlet pipeline comprises a main water inlet pipeline, and water inlet branchpipelines which are correspondingly connected with the closed cooling towers; the water outlet pipeline comprises a main water outlet pipeline, and water outlet branch pipelines which are correspondingly connected with the closed cooling towers; and the water inlet branch pipelines and the water outlet branch pipelines are correspondingly provided with switching valves. Compared with the prior art, the system has the advantages of low energy consumption, prolonged service life of equipment, stable operation and the like.

Description

technical field [0001] The invention relates to cooling equipment, in particular to a cooling tower cooling system based on flow change and its application. Background technique [0002] Cooling equipment is widely used in petrochemical, oil refining, fertilizer, coal chemical, metallurgy, electric power and other industries. Cooling tower is a relatively commonly used cooling equipment. The cooling tower is a device that uses water as a circulating coolant to absorb heat from the waiting system and discharge it to the atmosphere to reduce the water temperature. The existing cooling water system adopts a closed cooling tower cooling tower, and the demand-side equipment adopts temperature difference adjustment. Generally, multiple cooling towers are used to ensure that when the demand-side load changes and the cooling water flow changes, the frequency conversion of the fan motor can be relied on. To adjust and match, because the load changes greatly in different time periods...
