CN-224226716-U - Low elevation vacuum desorption deaerator

Abstract

The invention discloses a low-elevation vacuum desorption deaerator, which relates to the technical field of deoxidizing equipment and comprises a gas-water separator, wherein a water ring type vacuum pump is connected to the gas-water separator, and the deaeration in the first stage is realized by adopting an independent vacuum deaeration mode. The external vacuum pump only sucks the oxygen-containing gas resolved in the vacuum tank, does not suck the oxygen-containing gas in the rear resolving tank, ensures that the vacuum tank is in a final vacuum state, and deoxidizes in the second stage by adopting pure desorption. The water after deoxidization in the first stage is sent into a desorption tank through a water diversion system consisting of a water diversion pump, a water diversion ejector, an accessory pipeline and a valve, the desorption tank is guaranteed to be in a normal pressure state, a reactant is not simply prevented from being placed in the reactor, and a three-way catalytic device is placed at the upper part of the reactant, so that a small amount of carbon monoxide generated by the existence of a high-temperature section is converted into carbon dioxide in the reaction of oxygen-containing gas and reactant activated carbon, and the oxygen affinity of the mixed gas in water is improved.

Description

Low elevation vacuum desorption deaerator Technical Field The invention relates to the technical field of deoxidizing equipment, in particular to a low-elevation vacuum desorption deoxidizer. Background The normal temperature deoxidizing equipment used as a boiler consistently adopts a chemical deoxidizer, a vacuum deoxidizer and a sponge iron deoxidizer, and mainly adopts the vacuum electrochemical three-in-one deoxidizer or the vacuum analysis electrochemical three-in-one serial deoxidizer in recent years, but has two defects that the vacuum electrochemical three-in-one deoxidizer is difficult to overcome, firstly, as the water diversion pump in the vacuum destruction device has partial deoxidized water backflow, but the water backflow water can not offset the vacuum degree in the vacuum tank, the phenomenon that the water diversion pump can not absorb water under high vacuum still can not be overcome, the water diversion pump can not supply water under high vacuum condition can not be solved, so that in order to avoid the water supply interruption problem which often occurs, an equipment manufacturer adopts an electrical control measure, so that the equipment is kept at-0.05 to-0.06 MPa and runs under lower vacuum degree, the low vacuum degree of the equipment is not thorough, the effect of the vacuum oxygen removal is not fully utilized, the effect of the first vacuum deoxidization is increased, the second-level element, the negative electrode deoxidization is needed, the residual electric energy of the trivalent iron (Fe+ is the best removed by the electrolytic iron (the best after the electrolytic iron is the boiler is the standard iron, and the best 2+ is the residual iron, and the iron is the most of the best removed by the electrolytic iron (the iron standard, and the iron is the best 2): 1, as the vacuum degree is continuously adjusted (the vacuum degree is higher than a set value and the vacuum breaking valve is required to be opened to supplement air into the equipment), 2, because the deoxidization effect of high vacuum cannot be fully exerted, the electrolysis stage consumes larger electric energy and is extremely easy to cause the exceeding of the standard of iron ions of water supply. Compared with the prior vacuum electrochemical chemical three-in-one deaerator which is not fully popularized and used at present, the deaerator has the defects that 1, as all oxygen-containing gas is sent to the heater to be treated by the deaerator reaction, the deaerator is excessively large in consumption of the reactant, and the electric energy loss provided for the reaction is also excessively large, the deaerator is excessively large in consumption of the deaerator, and the deaerator is completely increased in operation cost, and the deaerator is accelerated in addition frequency, so that inconvenience is brought to operation, 2, as all oxygen-containing gas is treated by the heater, the deaerator is required to be more electric energy, and compared with the vacuum electrochemical three-in-one deaerator, the deaerator is larger in electric energy consumption, and the excessive electric energy consumption is not in accordance with the energy-saving requirement, 3, as each container of the deaerator is in a vacuum state, and the last vacuum container is led out by the water diversion pump, so that the deaerator is completely utilized, and the deaerator is completely high in the oxygen-saving effect (3, the high in oxygen-removing effect is still not required due to the fact that the water diversion pump is completely utilized, and the first level is not completely high in the oxygen-level-free oxygen-free effect is still produced).
