The pressure filter uses the pressure applied at the inlet of the suspension or the mechanical pressing force applied to the wet material as the filtering driving force. It is suitable for suspensions that require a large filtration pressure difference. It is also divided into intermittent operation and continuous operation. Intermittently operated inline and pressure filters are used for low concentration suspension filtration. The filter is also a type of intermittent operation pressure filter, which is divided into plate and frame type, box type and vertical type, which has a wide range of uses. The oil filter is a plate and frame filter press unit equipped with accessories such as oil pumps and vacuum evaporators. Continuously operated rotary drum pressure filter and disc pressure filter perform pressure filtration in a closed casing, and their structures are similar to that of rotary drum vacuum filter and disc vacuum filter. Due to the complex structure, there are few applications.

Multiple Effect Evaporator (MEE): In a multi-effect evaporation device, the steam generated by heating the first effect with new steam does not enter the condenser, but is reused as a heating medium for the second effect. This can effectively reduce the consumption of new steam by about 50%. Reusing this principle can further reduce the consumption of new steam. The maximum heating temperature of the first effect and the minimum boiling temperature of the last effect form a total temperature difference, which is distributed among the effects. As a result, the temperature difference per effect decreases as the number of effects increases. Therefore, the heating area must be increased to achieve the specified evaporation rate. Preliminary estimates indicate that the effective heating area increases in proportion to the efficiency, so that the amount of steam saved gradually decreases while the investment cost increases significantly.

The company advocates science and technology, quality, and efficiency at the same time, bold exploration, courageous, and perfect. Your satisfaction is our wish. We adhere to this concept and continuously strive to improve our software and hardware capabilities.

MVR evaporator is easy to operate, compact equipment, small footprint, and small space required. For existing plants that require expansion of evaporation equipment with insufficient gas supply, water supply capacity, and insufficient space, especially for low-temperature evaporation where frozen water condensation is required You can receive both investment savings and better energy saving results.

The heat pump compressor is the key equipment for increasing the temperature and pressure of the steam by compressing the steam generated by the heat recovery system. The effect is to increase the temperature of the steam from the reboiler (evaporator) under pressure to achieve the temperature and pressure requirements required by the process. The overall composition of this equipment is relatively complex, mainly consisting of three units: compression system, steam desuperheater and lubrication system. The steam generated in the evaporator is removed by the built-in wire mesh defoaming separator, and then enters the heat pump compressor. Since waste heat recovery is an important area of energy saving and emission reduction in the chemical process, the compressor is used to increase the temperature and pressure of the secondary steam and increase its enthalpy. Then reuse its heat. The heat pump can increase the steam temperature by 15-20 degrees, and the working range is 70 ~ 100 ℃.
