Sealed type circulating water cooling device and method

Abstract

The invention discloses a sealed type circulating water cooling device and a method. The device comprises an inner cooling device, a plate type heat exchanger (7) and an ice storage auxiliary cooling device, wherein the inner cooling device comprises an air cooler (3); the ice storage auxiliary cooling device comprises an ice storage cooling device (9); and inner cooling water which flows through the inner cooling device of the plate type heat exchanger (7) exchanges heat with outer cooling water which flows through the ice storage auxiliary cooling device of the plate type heat exchanger (7). The sealed type circulating water cooling device and the method provided by the invention improve the cooling capability of the cooling device and solve the problem that the cooling device still has enough cooling capability when the environment temperature is greater than or equal to the permitted highest water inlet temperature of process equipment; and in the operation process of the equipment, no water is lost, so that the aim of water conservation is achieved.

Description

Technical field [0001] The present invention relates to the field of cooling devices, in particular to a closed circulating water cooling device and method for cooling water passing through an air cooler through a plate heat exchanger. Background technique [0002] At present, many domestic power generation and transmission power stations, such as converter stations, are built in the arid and water-deficient northern regions. These regions often have the characteristics of high summer temperature and large water evaporation, so water resources are more precious. However, if ordinary water cooling methods are used to cool the equipment of power generation and transmission stations such as converter stations, it may consume the local scarce water resources. Therefore, the common cooling equipment of these power stations uses air coolers. Because the ambient temperature at the converter station is relatively low, the use of air coolers can meet the cooling needs of the power station...

Problems solved by technology

Therefore, it is not appropriate to apply only air coolers at this time

[0004] At the same time, since power generation equipment and power transmission equipment are often operated with the largest specifications in the hottest summer, and this is the time when the ambient temperature is the highest and most extreme, the air cooler often does not have sufficient cooling capacity in this case, making the replacement The flow station has to take the form of reducing load and power, which brings great economic losses and is not conducive to the healthy development of the national economy.
