Device for collecting and discharging effusion in multilevel vacuum unit equipment system

Abstract

The invention discloses a device for collecting and discharging effusion in a multilevel vacuum unit equipment system. The device comprises an effusion discharging tank, wherein the effusion discharging tank comprises a tank body; a collecting pipe communicates with one side of the top of the tank body, and an inspiratory pipe communicates to the other side of the top of the tank body; a discharging pipe communicates with one side of the bottom of the tank body; a liquid inlet valve is fixedly connected to the inner part of the collecting pipe; an inspiratory valve is fixedly connected to theinner part of the inspiratory pipe; an electromagnetic valve is fixedly connected to the inner part of the discharging pipe; and a transparent sight glass is fixedly connected to one side of the backsurface of the tank body. The invention relates to the technical field of chemical machinery. Through the adoption of the device for collecting and discharging effusion in the multilevel vacuum unit equipment system disclosed by the invention, effusion accumulated at the bottom of the vaccum unit can be discharged, so that the situation that the effusion is subjected to flood irrigation to a vacuum oil pumping cavity to pollute lubricating oil is avoided, equipment damage is reduced, influence on the vacuum degree of the vacuum system is reduced, the technology control of vacuum rectificartionis stabilized, and the production efficiency and the product quality are improved.

Description

technical field [0001] The invention relates to the technical field of chemical machinery, in particular to a device for collecting and discharging effusion in the equipment system of a multi-stage vacuum unit. Background technique [0002] The vacuum system is an important part of the direct air cooling system. Its function is to establish and maintain the low back pressure of the steam turbine unit and the vacuum of the condenser. When the unit is started, the air accumulated in some steam and water piping systems and equipment In order to speed up the start-up, the steam, water, and air and other non-condensable gases leaked into the vacuum system are removed in time during normal operation, so as to maintain the vacuum of the air-cooled condenser and reduce the corrosion of equipment, etc., and the low-pressure part of the steam turbine Shaft seals and low-pressure heaters also rely on the normal operation of the vacuum pumping system to establish a corresponding vacuum,...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for collecting and discharging liquid accumulation in the multi-stage vacuum unit equipment system, which solves the problem that the liquid accumulation in the vacuum unit is easy to flow back to the inside of the vacuum oil chamber after the accumulation of liquid accumulation in the vacuum unit reaches a certain level Thus polluting the lubricating oil, causing damage to the equipment, and also affecting the vacuum degree of the vacuum system and reducing the service life of the equipment
