Catalyst thickener (also known as thickener or concentrator) is one of the main equipments in the production process of many chemical raw materials such as aniline, TDI, MDI, BDO, etc., and is widely used. Its main function is to separate the expensive catalyst solid particles from chemical products such as aniline, and then re-enter the reaction vessel to continue to participate in the reaction. The catalyst thickener device outputs the chemical product pure liquid without catalyst solid particles, and its output. The pure liquid has a solid content of less than 0.001%. Its filtration principle is a new type of filtration. In principle, it is close to the combination of cross-flow filtration and filter cake filtration. 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 output. The pure liquid of the product, and the concentrate obtained after the other part is concentrated, needs to be returned to the production process to continue to participate in the reaction.
On the basis of fully digesting and absorbing the essence of similar equipment technology from abroad, the company has independently developed a new generation of catalyst thickener equipment with advanced level. The catalyst thickener produced by our company is generally driven by the under-explosion-proof motor. According to customer demand, the production of the above-mentioned explosion-proof motor drive type), the motor directly drives the spindle of the equipment through the reducer, and the explosion-proof motor adopts the advanced frequency conversion speed control system for stepless speed control. Compared with the traditional hydraulic drive method, this innovative design has many advantages such as high transmission efficiency, low noise, good reliability, trouble-free running time and long service life. The energy saving effect can reach more than 40%, and the noise can be controlled to 85 decibels. In the following, in line with national noise and environmental protection requirements, the spindle speed can be remotely adjusted and controlled with the DCS of the host computer. The special mechanical seal flushing isolating pump station can lubricate and cool the mechanical seals well, so that it can work under ideal working conditions, which can effectively prolong the trouble-free operation cycle of the mechanical seals. The mechanical isolation device's flushing and isolating fluid system performs real-time monitoring of individual flow, pressure and temperature. It can detect the possible problems of the mechanical sealing device and issue an early warning, so that the operator can detect and eliminate the fault in time and prevent it. The problem is magnified, effectively reducing operational risks and costs. In addition, the thickener equipment produced by our company can increase the flushing system of flushing the filter disc with clean water and its attached desalinated water cleaning pipeline system according to the needs of users.
