1. When water-ring pump extracts gas, the extracted gas is mixed with operating liquid, and the water exhausted at water exhaust port contains partial organic solvent and poisonous subatance, the discharge of a large amount of water causes heavy pollution to the environment.
2.The water containing organic solvent and poisonous substance will release harmful gas will aggravate environmental pollution.
3.The extracted organic solvent can't be easily recycled and will be wasted.
    In view of the above problems, more and more chemical, pharmaceutical enterprises have adopted closed-circuit circulation system of water-ring vacuum pump.
The main components of closed-circuit circulation system:
Liquid-ring vacuum pump/compressor
Gas-liquid separator
Heat exchanger
Common Chassis
Internal pipeline
Main Features:
1.This unit is supplied as compelete equipments, including gas-liquid separator, condenser(heat exchanger), unit rack, internal pipeline. Â It's easy for users to install this unit and greatly shorten installation period.
2.Operating liquid can adopt water or various chemical slivents, which can greatly reduce environmental pollution from chemical enterprises.
3.If adopting extracted medium as operating liquid, extracted medium can be recycled.
4.Belonging to non-standard products, 2BW series closed-circuit circulation systems are designed according to users' specific requirements on the conditions of inlet, cooling water, and exhaust port etc.
A shell and tube heat exchanger is a type of heat exchanger that is commonly used for heating, cooling and condensing applications. lt consists of a shell with an internal bundle of tubes,which allows the hot and cold fluids to pass through the walls of the exchanger and exchange their energy. Shell and tube exchangers are classified in several ways, including design, operational construct, and construction materials. Mainly Fixed Tube Heat Exchanger, Floating Head Heat Exchanger, U-tube Heat Exchanger, and double tube heat exchanger.
The working principle of a shell and tube heat exchanger is relatively simple. The system is designed with two separate flows on either side of the heat exchanger. The primary flow of the hot fluid passes through the tubes, while the secondary flow of the cold fluid passes through the spaces between the tubes. Heat is then transferred from the hot side to the cold side via conduction, leading to an exchange of temperatures.
Shell and tube heat exchangers are normally used in process plants and used in a wide range of applications. A case in point is the cooling of condensates in refineries and nuclear power plants. In this application, condensate is heated using an external source and passed through the tube section of the heat exchanger. This condensate is then cooled and condensed as it passes through the shell side, where the heat is transferred to a cooling medium such as water, steam or oil.
