Description

Technical Field

[0001] The utility model relates to the technical field of exhaust, in particular to a vacuum degasser. Background Art

[0002] There will inevitably be some air in the heating and cooling water circulation systems, and its sources are system make-up water and pipeline leakage. This part of the gas exists in three forms in the system: the first form is that the gas accumulates in the high points or local high points in the system in the form of air masses, such as pipeline corners, the tops of heat exchangers (radiators, fan coils), etc.; the second form is that the gas exists in the form of free bubbles and moves with the water circulation in the system; the third form is that the gas is dissolved in water and moves with the water circulation.

[0003] Among the above three forms of gas existence: the first and second are free gases, and the third is dissolved gas. The three will constantly transform into each other, but when there is no change in external conditions, the amounts of their various forms of existence will be relatively stable. The air existing in water will bring many adverse effects to the heating and cooling water circulation systems. The accumulated gas generates air resistance, causing uneven system resistance, poor system circulation, generating noise and cavitation. These problems will reduce the effective head and operating efficiency of the water pump, reduce the service life of equipment and pipelines, and the bubbles attached to the surface of the heat exchanger will reduce its heat transfer efficiency. The system air resistance makes system commissioning difficult, and manual air exhaust is often required during operation. Vacuum degassing and deoxidation adopt the principle of differential pressure degassing and can be applied to any system. Its extremely strong degassing ability can ensure the safe and rapid removal of free and dissolved gases in the system, enabling the system to operate safely and reliably. The existing vacuum degassers have relatively large structures, occupy a relatively large area, and have high requirements for the production site. Summary of the Utility Model

The higher end of the middle section of the support frame inclines outwards, and the higher end of the upper section of the support frame inclines inwards.
