Problems solved by technology

At present, vacuum pumps are used to remove these bubbles. However, the bubbles are corrosive and viscous, and they can easily cause damage to the vacuum pump when they enter the vacuum pump. Negative pressure is also difficult to control
In addition, the current speed of the vacuum pump is controlled by a pressure sensor. When the vacuum degree drops, the vacuum degree is increased by increasing the speed of the vacuum pump or adding liquid to the vacuum pump; The sensitivity of electrical components such as sensors will be affected

Abstract

The invention discloses an automatic pneumatic control scum defoaming negative pressure system. If a pressure sensor controls the rotary speed of a vacuum pump, a fault is easy to occur. The automaticpneumatic control scum defoaming negative pressure system comprises a vacuum generation device, a fluid supplementation device and a separation liquid storage tank, wherein the fluid supplementationdevice comprises a support pipe I, a compensation pressure-stabilization tank, a valve body and a magnetic drive valve; and two chamber groups arranged symmetrically are arranged on the valve body, and comprise chambers I, chambers II, chambers III, chambers IV, chambers V, valve rod slideways I, valve rod slideways II, pressure channels II and fluid supplementation ports sequentially arranged from bottom to top. According to the automatic pneumatic control scum defoaming negative pressure system provided by the invention, no any electric element is adopted, and a supplemented fluid can be automatically sprayed when the negative pressure is reduced, so that the occurrence of the phenomenon that a spiral blade works without a medium so as to heat to cause damage is avoided; and in addition,before scum foams contact a screw blade, corrosive elements are firstly filtered through a filter filler, and heating is carried out through a heat-preservation medium, so that the occurrence of thephenomenon that the corrosive and viscous bubbles contact the screw blade so as to cause the damage of the screw blade is avoided.

Description

technical field [0001] The invention belongs to the technical field of vacuum transportation, and in particular relates to an automatic air-controlled negative pressure system for removing scum and foam. Background technique [0002] There are usually some scum floating on the surface of the waste residue wastewater discharged during the production and processing of the petroleum and petrochemical industry. These scums are oily, corrosive media, and viscous. After cooling, they will solidify and form surface bubbles. The gas in the bubbles accounts for 98%- 99%. At present, vacuum pumps are used to remove these bubbles. However, the bubbles are corrosive and viscous, and they can easily cause damage to the vacuum pump when they enter the vacuum pump. Negative pressure is also difficult to control. In addition, the current speed of the vacuum pump is controlled by a pressure sensor. When the vacuum degree drops, the vacuum degree is increased by increasing the speed of the ...
