Description

TECHNICAL FIELD

[0001] The utility model relates to ion exchange technical field, concretely relates to a fluid treatment device. BACKGROUND

[0002] When ion exchange is carried out to fluid, fluid treatment device is generally used, and the fluid treatment device can simultaneously carry out ion exchange or ion regeneration to multiple containers. First, ion exchange resin is put into the multiple containers, and the multiple containers are communicated with the fluid treatment device through pipelines. One kind of fluid is guided to pass through one or more containers through the fluid treatment device, and another kind of fluid is guided to pass through other containers for ion exchange resin regeneration or other purposes.

[0003] After ion exchange resin in the container carries out ion exchange for a period of time, the ions in the resin are exhausted, and the resin in the container needs to be regenerated. At this time, the fluid treatment device needs to be moved, so that the fluid treatment device guides the regeneration fluid into the container that needs to be regenerated. The fluid to be treated is guided by the fluid treatment device into the container that has completed ion regeneration to continue ion exchange.

[0004] In the fluid treatment device disclosed in the related technology CN1452513A, as shown in Figure 1 and Figure 2 , the rotating disc 12 is arranged in the fixed shell 13, and the rotating disc 12 is provided with channels on the side. These flow channels for distributing each type of fluid and the communication channels for connecting each container are fixedly arranged in the rotating disc 12 by machining. When the use process needs to be adjusted, the valve body can only be re-manufactured to meet the requirements. In addition, due to the arrangement of the rotating disc 12 in the fixed shell 13, a sealing strip needs to be arranged when each fluid needs to be distributed. However, the sealing strip can only be arranged on the outer side of the rotating disc 12. Due to the structure, the sealing strip can only be pressed on the rotating disc 12 in the middle by the pressing force of the top of the valve body. The rotating disc 12 and the fixed shell 13 are sealed by friction, which results in low sealing pressure, unreliable performance, and easy leakage. In addition, the structure is complex, the design and machining are difficult, the cost is high, the connection relationship between the component and the container cannot be changed when the process needs to be adjusted, the process adaptability is low, and the multiple adsorption columns cannot make the resistance completely the same, which results in different differential pressure and uneven actual feed flow of each adsorption column.
