Description

End cap type rubber ball cleaning machine Technical field

The invention relates to a matching product of a condenser/evaporator. It is an end cover type rubber ball cleaning device with an online rubber ball cleaning function. It is suitable for double-process water-cooled water chiller shell-and-tube condensers and double-process shell-and-tube condensers. A full-liquid evaporator, and a dual-process water-cooled shell-and-tube heat exchanger with the cooling water running through the pipe and the temperature does not exceed 80°C.

Background technique

There are three types of automatic online cleaning devices for condensers of existing chillers: The first type is an independent cleaning system device, which is connected with the condenser inlet and outlet pipes through pipes. The ball machine sends the rubber ball to the water inlet pipe of the cooling water, the rubber ball With the cooling water flowing into the condenser, after cleaning, it flows out from the cooling water outlet, enters the ball catcher, and then enters the ball machine. This type of cleaning device is mainly installed on the connecting pipe of the cold water host and needs to be installed separately, which is more troublesome; The second type is to install a four-way reversing device at the inlet and outlet of the condenser. The condenser heat exchange tube is equipped with a cleaning element, and the cleaning element is reciprocating through the four-way reversal direction to clean the inner wall of the heat exchange tube. For details, see the publication number. It is the invention patent of CN104151297A. However, this type of automatic cleaning device by reversing the direction has two drawbacks: 1. High temperature water enters the condenser during the reversal, causing the refrigerant condensation temperature in the condenser of the chiller to change greatly, and the chiller instantaneously The efficiency fluctuates greatly, which will have a greater impact on the operation of the chiller, and cause side effects such as surging of the chiller in severe cases; 2. Due to the distribution of the water flow field in the condenser tube sheet, the flow rate in each heat exchange tube is different, so After running for a period of time, some cleaning elements cannot perform reciprocating cleaning motion and are stuck in the blocking element; the third type is a water-cooled water-cooled chiller shell-and-tube condenser front-end tube box with rubber ball cleaning function. Details can be seen in the public. Patent No. CN208805095, this equipment is equipped with a power pump, which consumes a lot of energy. At the same time, due to the actual engineering application, the ball collecting filter will intercept the impurities in the water flow, and the accumulation of impurities over time will block the ball collecting filter. As a result, the rubber balls are often blocked in the ball collecting filter, and the rubber balls cannot be recovered smoothly.
