Combined Flow Closed Cooling Tower
Closed Cooling Tower is operated by circulating water or fluid, which is divided into two closed loops.
1. Circulation in the tower: the circulating water or fluid passes through the hot zone environment. After the water temperature rises, it enters the surface cooler in the tower, and the heat is sent to the environment outside the tower through the surface cooler and ventilation fan. The cooled circulating water or fluid is sent to the heat source by the water pump.
2. Circulation outside the tower: the spray water is sent to the spray system by the water tank through the water pipe. After spraying, the spray water first exchanges heat with the filler, so that the spray water can be cooled rapidly. At this time, the water contacts the surface of the surface cooler for heat exchange. Part of the hot steam is discharged through the ventilation fan, and the cooled spray water drops to the water tank for secondary circulation to form an external circulation for cooling.

Compared with developed countries, the gap between products and technology in China's packaging machinery industry is mainly reflected in the following aspects: From the perspective of product structure, there are only 1,300 kinds of packaging machinery in China, with a small number of supporting products, lack of high precision and large-scale chemical products. The product quality gap is manifested in low product performance, poor stability and reliability, unsightly appearance, rough surface treatment, poor quality of many components, short life and low reliability, which affects the quality of the overall product.
China's packaging machinery exports, from "small" to "big", from the low end to the high end, showing a diversified product situation. The export packaging machinery basically covers the existing product categories, and different levels of packaging machinery have different sales markets. In the future, China's packaging machinery exports, while continuing to maintain price advantage, should increase the export share of large-scale complete sets of equipment and high-tech products, and strive to seize the technical commanding heights.
China's packaging machinery is at a disadvantage compared to international products.
From the perspective of the company's situation, the domestic packaging machinery industry lacks leading enterprises, and there are not many enterprises with large production scale and high products. From the perspective of product development, China still basically stays in the test imitation stage, with weak self-development capability and lack of scientific research and production pilot bases. Little research funding. In general, compared with international products, China's packaging machinery is at a disadvantage in terms of product development, performance, quality, reliability, and service.
