primary structure

The hot well unit is an important component in the ship's steam system, mainly used for collecting and processing condensate in the steam system. It is usually composed of the following parts:

1. Hot well body: The hot well body is a container for storing condensate, usually welded from steel plates. The interior of the hot well body usually has partitions to increase the residence time of the condensate and improve the quality of condensate filtration.

2. Atmospheric condenser: The atmospheric condenser is an important part in the hot well unit, and its role is to condense the steam in the steam system into water and collect it into the hot well body. The atmospheric condenser is usually made of copper tubes or steel tubes, and its interior is provided with cooling water pipes, through which the steam is condensed into water by the cooling water in the cooling water pipes.

3. Condensate observation tank: Its role is to observe the condensate water level and water quality in the hot well body. The condensate observation tank is usually made of transparent materials such as glass or plexiglass.

4. Automatic make-up water valve and manual make-up water valve: Their role is to replenish water into the hot well body to keep the water level in the hot well body stable. The automatic make-up water valve is usually made of solenoid valve or electric valve, and its opening and closing are controlled by the water level controller. The manual make-up water valve is usually made of ball valve or gate valve, and its opening and closing are manually operated.

5. Oil and salt content detector: Oil content, its role is to detect the oil and salt content in the hot well body to ensure that the water quality in the hot well body meets the requirements. The oil and salt content detector is usually composed of sensors and displays, and the detection results can be displayed through the display.

6. Thermometer and temperature controller: Their role is to measure and control the temperature in the hot well body to ensure that the temperature in the hot well body meets the requirements. The thermometer is usually made of thermocouple or thermal resistance, and the measurement result can be displayed through the display. The temperature controller is usually made of electronic components, and the control result can be achieved through solenoid valve or electric valve.

7. High and low water level controllers: Their role is to measure and control the water level in the hot well body to ensure that the water level in the hot well body meets the requirements. The high and low water level controllers are usually made of float switches or electrode-type level switches, and the measurement results can be achieved through solenoid valve or electric valve.

8. Boiler feed water pump and electric control box: The boiler feed water pump and electric control box are two important components in the hot well unit, and their role is to transport the hot water in the hot well body to boilers or other equipment for use. The boiler feed water pump is usually made of centrifugal pump or plunger pump, and its flow and head can be selected according to needs. The electric control box is usually made of electrical components, and the control result can be achieved through contactor or relay.

main function

The functions of the hot well unit mainly include the following aspects:

1. Collecting condensate water: The hot well unit can collect the condensate water in the steam system to avoid waste and pollution caused by the direct discharge of condensate water into the environment.

2. Treating condensate water: The hot well unit can treat the collected condensate water to remove impurities and salts therein and improve the quality of the condensate water.

3. Providing hot water: The hot well unit can store the treated hot water for use by boilers or other equipment, thereby improving the energy utilization efficiency.

4. Maintaining stable water level: The hot well unit can replenish water into the hot well body through the automatic make-up water valve and the manual make-up water valve to maintain the stable water level in the hot well body.

5. Controlling temperature and pressure: The hot well unit can control the temperature and pressure in the hot well body through devices such as thermometers, temperature controllers, high and low water level controllers, etc. to ensure that the hot water in the hot well body meets the requirements.
