Condensate expansion container

It should mainly be used for expansion. Search results on Baidu for reference. Sewage expansion vessel 1. Overview. The continuous sewage expander is also called a continuous sewage expansion vessel. The design and manufacturing should be carried out in accordance with the pressure vessel GB150-98. The continuous blowdown expander is connected to the continuous blowdown port of the boiler and is used to depressurize and expand the continuous blowdown of the boiler. The blowdown water is adiabatically expanded and separated into secondary steam and waste hot water in the continuous blowdown expander. It is expanded, depressurized, and heat exchanged in the expander, and then discharged. The secondary steam is led out through a special pipeline, and the waste hot water is automatically drained away through the float level valve or overflow control valve. The heat energy can be recovered and reused. The continuous discharge volume is automatically adjusted as the boiler feed water load changes to maintain a relatively stable discharge rate. 　　Therefore, the use of secondary steam and waste hot water as heat sources can recover part of the heat lost by continuous blowdown of boilers and improve boiler efficiency. 　　2. Working process: Boiler wastewater is continuously and evenly connected to the wastewater expansion vessel. The wastewater moves tangentially in the cylindrical partition in the middle of the shell and is immediately vaporized into secondary steam. After passing through the upper shutter-type steam-water separator for steam-water separation, it is introduced into the deaerator through the outlet at the top of the continuous row, and the remaining wastewater is discharged through the water level regulating valve. 　　3. Operation precautions 1. When the boiler requires a large amount of sewage discharge, or when the liquid level regulating valve fails, the bypass valve should be opened to increase the sewage discharge. 　　2. The opening of the top exhaust valve should be adjusted to maintain the working pressure in the row. 　　3. Adjust the opening of the liquid level regulating valve so that the water level in the row is in the middle of the water level gauge. 　　4. The working pressure of the safety valve must be adjusted according to regulations. 　　5. This equipment can provide sewage discharge for two boilers at the same time. If it only supplies one boiler, the water inlet flange of the other one should be blocked by a bulkhead.
