Description

Technical Field

[0001] The utility model relates to the technical field of sewage expansion containers, in particular to an energy-saving continuous sewage expansion container. Background Art

[0002] Continuous sewage expansion device is also called continuous sewage expansion tank. Its design and manufacture should be carried out in accordance with GB150-2011 for pressure vessels. The continuous sewage expansion device is connected to the continuous sewage outlet of the boiler and is used to reduce the pressure and expand the continuous sewage of the boiler. The sewage is adiabatically expanded in the continuous sewage expansion device and separated into secondary steam and waste hot water. The sewage is expanded, reduced in pressure, and heat exchanged in the expander before being discharged. The secondary steam is led out by a special pipeline, and the waste hot water is automatically discharged through a float level valve or an overflow regulating valve. The heat energy can be recovered and reused. The continuous sewage volume is automatically adjusted with the change of the boiler feed water load to maintain a relatively stable sewage discharge rate.

[0003] When the sewage expansion tank in the existing technology is in use, although the sewage expansion tank can separate some steam for thermal deoxygenation or other purposes when treating sewage, the remaining high-temperature waste hot water is often directly discharged into the ditch or discharged after cooling. The large amount of heat energy contained in these waste hot water cannot be effectively utilized. The temperature of the waste hot water after treatment by the continuous sewage expansion tank may be as high as 100°C or above. Direct discharge not only wastes heat energy, but may also cause thermal pollution to the environment. Therefore, we need an energy-saving continuous sewage expansion tank. Utility Model Content
