Usually, when the heat exchanger in the fiber and large particles exist, the device backwash effect is quite obvious. Use one of the following two ways to achieve the purpose of backwashing:
⑴ with water and normal operation in the opposite direction of the washing device.
⑵ layout of the pipeline and set the valve in the pipeline, so that in a fixed time in the product side in reverse mode operation. This special mode is particularly suitable for products that are steam heat exchangers.
⑶ When the water flow contains a considerable amount of solid or fiber material, it is recommended in the heat exchanger in front of the water supply line installed filter. This reduces the number of reverse flushing.
