The principle of the CIP cleaning machine is to add concentrated acid and concentrated alkali to the cleaning solution through a metering pump. After the mixing tank is prepared, it is controlled by a valve. After being heated by the built-in coil heat exchange system in the mixing tank, it is increased by the pump to increase the pressure and increase the flow rate. The rotating spray ball and the impact force of the rotating spray product are used to clean and dissolve the dirt on the inner wall of the container to achieve the cleaning purpose. The cleaning of the pipeline relies on the booster pump to increase the flow rate of the cleaning liquid to generate end-flow to achieve the purpose of circulating cleaning.

MVR evaporation system evaporation has decreased. Cause: The inner wall of the main heater has excessive scaling or deposits. Treatment method: Start and execute the system cleaning program, and perform on-line cleaning of the MVR evaporation system.

The material of the multi-media filter can be FRP, A3 steel anti-corrosion or rubber lining, and all stainless steel. There are two modes of operation: full-automatic and manual. The automatic control is controlled by automatic controllers and gas and hydraulic valves imported from the United States. The operation is simple and easy to maintain. It is widely used in pretreatment devices of water treatment processes in various industries. .

When using MVR evaporators, single or multiple stages can be considered. In the evaporation of salty wastewater, if the salt content of the material is low, in order to reduce the operating cost, membrane evaporation can be considered in the first stage. If a falling film evaporator is used, the forced circulation evaporator can be used in the second stage. This can greatly reduce operating costs. For the evaporation of some materials, the boiling point rises lower when the concentration is low, and the boiling point rises higher when the concentration is high. At this time, you can consider the combination of MVR evaporator and multi-effect evaporator.

1. Divided by evaporation method: natural evaporation: the solution evaporates at a temperature lower than the boiling point, such as sea salt, in this case, because the solvent only vaporizes on the surface of the solution, the solvent evaporation rate is low. Boiling evaporation: The solution is heated to the boiling point and allowed to evaporate in the boiling state. This is basically the case for industrial evaporation operations. 2. Divided by heating method: Direct heat source heating is an evaporation process in which fuel and air are mixed, and the high-temperature flame and smoke generated by combustion are sprayed directly into the evaporated solution through a nozzle to heat the solution and vaporize the solvent. The indirect heat source heats the walls of the container to the evaporated solution. That is, the heat transfer process in the partition heat exchanger. 3. According to operating pressure: can be divided into normal pressure, pressurized and reduced pressure (vacuum) evaporation operation. Obviously, for heat-sensitive materials, such as antibiotic solutions, fruit juice, etc., should be carried out under reduced pressure. High-viscosity materials should be heated by pressurized high-temperature heat sources (such as thermal oil, molten salt, etc.) for evaporation. 4. Divided by effect: can be divided into single effect and multi-effect evaporation. If the secondary steam generated by evaporation is directly condensed and no longer used, it is called single-effect evaporation. If the secondary steam is used as the next effect heating steam and multiple evaporators are connected in series, this evaporation process is multi-effect evaporation. 5. According to the use of steam and electricity: in the evaporation process, steam generators and mvr evaporators that use electricity to drive the compressor to compress the secondary steam are used in the evaporation process. During the evaporation process of the MVR evaporator, as long as steam is generated when the system is turned on, there is no need to pass steam after normal operation.

The five main industrial crystallizers are: (1) externally forced crystallizers, a. Crystallization is achieved by evaporation or cooling, b. With or without a buffer plate, c. Is taken away with a tube heat exchanger or direct contact Heat. (2) The internal forced-flow crystallizer using ventilation ducts, a. To achieve the product by evaporation or cooling; b. To use or not use a buffer plate, c. To use a tube heat exchanger or direct contact to remove heat. (3) Introduced seed crystallizer (Oslo crystallizer is typical). a. Crystallization is achieved by evaporation or cooling, b. Heat is removed with a tube heat exchanger or direct contact. (4) scraper surface heat exchanger; (5) discontinuous crystallizer (cooling or not cooling, stirring or not)
