WZI type external heating vacuum evaporator

一、An overview of the

The naming film evaporator is mechanical agitator thin-film evaporator, also known as rotary film evaporator, is the falling film evaporation under vacuum conditions in new high efficiency evaporator, it with high coefficient of heat transfer equipment (evaporation intensity), low temperature evaporation effect is good, the material stay time is short, the applicable wide viscosity range and large elasticity of operation, etc, in chemical industry, light industry, food, pharmaceutical and oil and many other industries are widely used.

二、Main properties and characteristics

1. The high heat transfer coefficient, evaporation efficiency high, to the evaporation of water and organic solvents such as solution.

2. Stay on the surface of the treated materials in evaporation time is short, coking, scale.

3. Can be achieved under the condition of vacuum evaporation at low temperature, the pressure loss is small.

4. Available low-grade steam.

5. Strong adaptability, suitable for continuous production, large elasticity of operation, simple structure, easy maintenance, can implement automatic control.

6. Change the scraper the outside of the groove Angle, can adjust the residence time of material in the evaporator, to adapt to the needs of different viscosity material evaporation.

Three, technical parameters

Evaporation of interior design pressure: 0.1 MPa (vacuum)

Job stress: - 680 MMHG ~ - 750 MMHG

Inside the jacket design pressure: 0.4 MPa pressure (table)

Working temperature: 100~ 380 ℃

Jacket in heating medium: saturated steam or heat conduction oil

Evaporation capacity: 100 kg/h? ) or higher (in water)

Note: 1. The above parameters, the user must show in order.

2. The vacuum degree, jacketed pressure and temperature can be separately designed according to need.

3. The material according to material physical and chemical properties.

4. The evaporation capacity in water as material, different material evaporation capacity is different, different concentrations of different materials the evaporation capacity.

五、The installation

1. Check the equipment caused by transportation reason is loose, the equipment before delivery has the overall test, adjustment, commissioning, user can't remove the installation (with the exception of motor speed closed).

2. The film evaporator when installation should try to avoid any damage to the equipment.

3. The equipment in hoisting rope or wire bundles are not allowed to be on the drive motor.

4. The evaporator must ensure that the vertical installation, calibration must be level, based on deceleration pattern in the rack end, there cannot be any stress pipe connection.

5. The evaporator is forbidden for any welding work.

6. The motor should be installed in the other parts until after.

7. It is forbidden to have foreign body into the film evaporator.

8. The evaporator upper bowl need to heat preservation, secondary steam outlet pipe should be outward tilt, to prevent the reverse condensate produced and affect the evaporation capacity.

9. The bottom of the evaporator must have enough maintenance space.

Six, operating instructions

After the completion of the hoisting equipment, according to the technological requirements with good pipeline, to clean, purging and pressure test system, qing foreign body, it is forbidden to have foreign body into the film evaporator. Check film evaporator and the purple lock nut at the top of mechanical seal is loose, if there is a need to tighten. Check the sealing system is good, if there is leakage point must be removed.

1. The drive to

Film evaporator motor running, check whether the mixing is required direction of rotation, shall not be reversed.

(2) check reducer lubricating oil (grease) within the prescribed scope of.

3. Check the sealing fluid mechanical seal up, didn't have to full fill, or check the balance tank of oil.

(4) check whether the mechanical seal cooling water is clear.

Drive 2.

After the completion of the preparations for regular driving driving.

(1) open the mechanical seal cooling water film evaporator.

(2) open the vacuum pump to vacuum system, the system of vacuum to achieve stability.

(3) open the
