MVR Industrial Wastewater Evaporator _ Shijiazhuang Huafang Machinery

Product Introduction:

There are various types of wastewater or sewage, with ever-changing characteristics and diverse treatment methods. Based on the characteristics of the liquid material, our company adopts①Multi effect evaporation process or②Multi-effect evaporation+Drying process or③Multi-effect evaporation+Crystallization process is used to treat sewage or wastewater, so that the water separated by evaporation meets the national discharge standards, and the moisture content of the dry matter after evaporation is lower than20%Our company adopts multi effect (usually3The efficient evaporation system not only achieves the goal of energy conservation and emission reduction, but also greatly saves costs. Many wastewater projects can also profit from it, and enterprises not only achieve good social and environmental benefits, but also obtain good economic benefits.

Our company can propose a comprehensive performance optimization process plan based on the specific parameters of the sewage or wastewater provided by the user, which can not only meet the drainage standards but also achieve good economic benefits, and manufacture equipment that satisfies the user.

Preheater: In most cases, the solution to be evaporated must be heated before entering the evaporator.

Evaporator: The solution that needs to be evaporated exchanges heat with the heat source vapor in the evaporator, resulting in evaporation. Select different types of evaporators based on the properties of different solutions.

Separators: Used for separating steam and liquid, different separators can be selected according to the properties of different solutions, generally including centrifugal separators, gravity separators, or separators with special structures.

Vacuum system: Maintain the vacuum degree of the entire system, extract some air, non condensable gases, and gases introduced by the solution from the device to achieve a stable evaporation state of the system.

Pump: Transport the solution to be evaporated and the concentrated solution. According to the different properties of the solution, different types of pumps can be selected, generally including centrifugal pumps, volumetric pumps, and screw pumps.

Control system: By controlling valves, flow meters, temperature, and pressure, automatic evaporation, cleaning, shutdown, and other operations are achieved to maintain dynamic balance of the system.

Cleaning system: After evaporating different solutions for a period of time, scaling may occur. Generally speaking99%The above scaling can be removed by adding chemical solvents, which can generally be usedCIPIn situ cleaning or dismantling cleaning.

Product features:

　　1.Fully automated equipment (also capable of semi-automatic operation) does not require dedicated supervision, is easy to operate, has good water quality treatment effects, and is clean without odor.

　　2.Save investment and operating costs (labor, electricity, steam consumption)

　　3.No need to add chemicals during runtime

　　4.The equipment is made of corrosion-resistant materials according to the characteristics of wastewater or sewage

　　5.The system is simple and easy to operate

　　6.The device has a small volume and occupies a small area

　　7.Stable equipment performance and continuous operation

　　8.Some evaporated water sources can be reused, which can save the cost of tap water

9.Some wastewater can be turned into gold as waste, and the concentrated or crystallized materials can be reused or sold to others to save energy and improve economic efficiency.

Evaporator operation is a commonly used unit operation, and operators should:“Four Understood”(Understand the structure, principle, performance, and purpose of the evaporator)“Four meetings”(Able to operate, maintain, inspect, and troubleshoot).

Operation of evaporator: strictly follow the operating procedures. Before driving, carefully check if there is water in the heating chamber, and prepare the pump, instruments, steam, and condenser pipelines. According to different device controls, operate and monitor according to pre-set programs.

Operation of evaporator: During equipment operation, careful operation and strict control are necessary. Operators should check and adjust the operation status of the evaporator at regular intervals and keep records. When the device is in a stable operating state, do not easily change the performance parameters.

Shutdown of evaporator: If the evaporator device is not started for a long time or needs to be emptied due to maintenance, it should be completely shut down; When performing minor repairs on the device and stopping it for a short period of time, the device should be kept in standby mode; It is difficult to predict every possible situation for accident parking, and emergency parking should be carried out.

The evaporator system should undergo daily maintenance: the main equipment evaporator is usually maintained using“Washing effect”(Also known as furnace washing), there are two methods for washing efficiency: large washing and small washing.
