Overview of drainage tank and pressure equalization tank:

Overview of drainage tank:

A drainage tank is used to store hydrophobic water, such as condensed water formed during the operation of low-pressure heaters and other steam equipment. Although there is a possibility of pollution in general, it is still relatively pure, and has good utilization value from both economic and energy saving considerations. So the drainage tank is a water storage device that stores and prepares the condensed water for use. The structure is divided into circular and square shapes, and the production series has a length of 10m 3、 20m 3、 30m 3、 40m 3、 50m 3。 The company can also design and produce according to customer needs.

Overview of pressure equalization box:

The function of the pressure equalization box: Its main function is to collect, distribute, and balance steam pressure, which is set up for steam seals. 1. Balance the expansion and pressure reduction of the steam entering and exiting the casing, adjust the pressure and temperature of the steam required for the start-up shaft seal to 2.94~29.4 KPa, with a temperature of 120~140 degrees, supply steam to the rear shaft seal during start-up. During normal operation, the shaft seal steam can also supplement the rear shaft seal steam, and collect the high-pressure side steam of the water control check valve for low-pressure extraction (three, four, five extraction); 2. Prevent the steam turbine shaft seal from flowing outward to improve the workshop environment; 3. Prevent low-pressure shaft seal from inhaling air and affecting vacuum; 4. During hot start, provide high-temperature shaft seal steam to the rear shaft seal.

The working principle of the pressure equalization box:

-It has two automatic adjustment doors (adjustable pressure).

During normal operation, when the steam volume of the unit is greater than the steam used for the rear steam seal, it will automatically discharge into the condenser to reduce environmental emissions.

And only when the steam volume of the unit is less than the steam used for the rear steam seal, the 2-extraction or low extraction steam is supplied to the equalizing box through it to ensure the steam supply for the rear steam seal.

The pressure equalization box has two automatic adjustment doors (adjustable pressure).

When the pressure equalization box is in normal operation, only when the steam volume of the unit is greater than the steam used for the rear steam seal, it will automatically discharge to the condenser to reduce emissions to the environment.

When the steam volume of the unit is less than the steam used for the rear steam seal, the 2-extraction or low extraction steam passes through it to supply steam to the equalizing box, ensuring the supply of steam to the rear steam seal.
