Description
Technical Field
The utility model relates to a deaerating plant, especially a deaerating plant that applicable when heating medium probably contains radiation or pollution source.
Background
At present, in the processes of external heat supply and nuclear fuel post-treatment heat supply of nuclear power plants and chemical plants, because a high-temperature medium on one side has radioactivity or contains pollutants, the high-temperature medium can be applied after physical isolation.
The conventional deaerator is of a type in which heating steam is directly mixed with incoming water to heat and deaerate the incoming water. The structure is simple and the heat loss is small. If the high-temperature medium is used for deoxidization, the conventional deaerator cannot meet the process requirements. Meanwhile, the heat of the high-temperature medium cannot be directly recovered, and the loss is large.
A new deaerating device is designed in consideration, so that the heat of the high-temperature medium can be utilized, and the safety of the quality of deaerated water is ensured.
In the chinese patent application "a process system for preparing deoxygenated water for a boiler using a high temperature heat pump system" published in 2013, 1 month and 23 days, and having publication number CN102889573A, a high temperature mixed working medium and low temperature oxygen-containing water exchange heat in a condenser, and the high temperature mixed working medium enters the condenser after being compressed by a compressor and then changed into a high temperature and high pressure state before heat exchange. The method also utilizes a partition wall mode to prepare the deoxygenated water, but the structure is relatively complex.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the prior deaerator can not be used for the utilization of the heat of high-temperature medium with radioactivity or pollutant-containing risk by directly utilizing the heating steam and water to carry out the deaerating treatment mode, and the utility model provides a dividing wall type deaerator with a horizontal deaerator head.
The utility model provides a technical scheme that its technical problem adopted is: take dividing wall formula deaerator of horizontal deoxidization head, including horizontal deoxidization head and steam converter, horizontal deoxidization head is installed on steam converter, and steam converter's steam outlet is direct as horizontal deoxidization head's steam inlet, or steam converter's steam outlet passes through the takeover connection horizontal deoxidization head's steam inlet. The heat exchange tubes of the steam converter are used as elements for isolating media on two sides, the high-temperature media and the circulating water are subjected to heat exchange, and the generated steam enters the deaerating head to heat the circulating water, so that the purpose of deaerating is achieved.
The steam converter is a kettle-type U-shaped heat exchanger, a heat release medium of the steam converter passes through a tube pass, a heat absorption medium of the steam converter passes through a shell pass, and a steam outlet of the steam converter is positioned on the shell side. Heating steam from a heat supply steam pipeline is used as a heat release medium and enters a tube pass, circulating water is used as a heat absorption medium and enters a shell pass, and the heating steam is sent to an oxygen removal head after being heated to form saturated steam with lower quality.
And a water level measuring and controlling device is arranged on the pipe side of the steam converter, so that steam is prevented from being discharged out of the equipment under the condition of no condensation.
And a water level measuring and controlling device is also arranged on the shell side of the steam converter, so that cavitation of a water pump arranged at a deoxygenated water outlet is avoided.
The utility model has the advantages that: the oxygen removal head and the kettle type steam converter are connected into a whole, so that physical isolation of a heating medium and a heat absorption medium is achieved, the purposes of heating and removing oxygen of deoxygenated water and no secondary pollution are achieved, the use safety is improved, the purposes of energy saving and consumption reduction are also achieved, and the nuclear power station can be applied to heat supply by utilizing nuclear energy, heat supply by utilizing waste steam in chemical plants and the like.
