      Catalyst thickener

      Catalyst Thickener (also known as thickener or thickener) is one of the main equipment in the production process of aniline, TDI, MDI, BDO and many other chemical raw materials.

Catalyst Thickener (also known as thickener or thickener) is one of the main equipment in the production process of aniline, TDI, MDI, BDO and many other chemical raw materials. Its main function is to separate the expensive catalyst solid particles from aniline and other chemical products, so that they can re-enter the reactor to continue to participate in the reaction. The catalyst thickener equipment outputs the pure liquid of chemical products without catalyst solid particles, and the output pure liquid solid content can reach below 0.001%. Its filtration principle is a new type of filtration, which is close to the combination of cross flow filtration and filter cake filtration in principle. It belongs to the category of dynamic continuous filtration. After the raw materials enter the catalyst thickener, some of them are filtered by high-precision filter cake and the pure liquid of the product is output, and the other part of the concentrated liquid is returned to the production link to continue to participate in the reaction.

On the basis of fully digesting and absorbing the technical essence of similar foreign equipment, the company independently innovates and develops a new generation of catalyst thickener equipment with advanced level. The catalyst thickener produced by the company generally adopts the driving form of lower explosion-proof motor (or the driving form of upper explosion-proof motor can be produced according to the needs of customers), and the motor is directly driven by the reducer The explosion-proof motor adopts advanced frequency control system for stepless speed control. Compared with the traditional hydraulic drive mode, this innovative design has many advantages, such as high transmission efficiency, low noise, good reliability, trouble free operation time and long service life. The energy saving effect can reach more than 40%, and the noise can be controlled to less than 85 dB, which meets the national noise environmental protection requirements. The spindle speed can be remotely adjusted and controlled with the upper computer DCS. The special mechanical seal flushing and isolating fluid pump station can lubricate and cool the mechanical seal device, make it work under the ideal working condition, and effectively extend the fault-free operation period of the mechanical seal device. At the same time, the pump station can monitor the flow, pressure and temperature of each mechanical seal device's flushing isolation fluid system in real-time, so as to discover the machine in the first time The mechanical seal device may have problems and give early warning, so that the operator can find and remove the fault in time, prevent the problem from expanding, and effectively reduce the operation risk and cost. In addition, the thickener equipment produced by our company can add the flushing system and its auxiliary desalted water cleaning pipeline system to flush the filter disc with clean water according to the needs of users.
