Automatic rotating film type deaerator

Abstract

The invention provides an automatic rotating film type deaerator. The automatic rotating film type deaerator comprises a water tank, a deaeration tower and a control assembly; the bottom of the deaeration tower is fixed on the water tank through a connecting seat, a first outlet communicated with the deaeration tower and the water tank respectively is formed in the connecting seat, a second firstoutlet is formed in one side wall of the first outlet, an L-shaped solenoid is arranged below the second outlet, one end of the L-shaped solenoid is positioned on the side wall of the first outlet, the other end of the L-shaped solenoid is positioned on the side wall of the second outlet, a first groove is formed in the position, right opposite to one end of the L-shaped solenoid, of one side wallof the first outlet, a second groove is formed in the position, right opposite to the other end of the L-shaped solenoid, of the side wall of the second outlet, a first magnet is arranged in the first groove, the end portion of the first magnet is connected with the bottom of the first groove through a first spring, a second magnet is arranged in the second groove, and the upper end of the secondmagnet is connected with the second groove through a second spring; and the control assembly comprises a single-chip microcomputer, a data collector, a display screen, an L-shaped solenoid power supply, a first dissolved oxygen sensor and a temperature sensor. The oxygen content in the water is automatically measured.

Description

technical field [0001] The invention relates to a deaerator, in particular to an automatic spin film deaerator. Background technique [0002] Dissolved oxygen and other gases in the water supply will cause corrosion of the water supply equipment and its pipelines, thereby affecting the safety and service life of the water supply equipment. The commonly used oxygen removal method is thermal oxygen removal. The principle is to use Henry's law and Dalton's law. For various gases dissolved in water, under a certain pressure, the higher the temperature of the water, the lower the solubility. Thermal deoxygenation is to use steam to heat water to the saturation temperature under the corresponding pressure, and the steam partial pressure is close to the full pressure on the water surface, so that various gases in the water are precipitated. [0003] The thermal rotating film deaerator is a new type of thermal deaeration equipment. The rotating film deaerator in the deaeration towe...

Problems solved by technology

Although it can achieve a certain deoxygenation effect, in the actual operation process, it is necessary to manually fetch water for dissolved oxygen detection to determine whether the treated water meets the standard
