1、 Application and technical features:
????? Energy saving device for exhaust steam recovery of deaerator It is a new type of energy-saving equipment specially for recycling the residual steam from deaerator of industrial boilers in power plant, petrochemical industry, papermaking, nonferrous metal smelting, textile printing and dyeing, etc. it cools the steam and heats the cooling water at the same time to make it recycled, eliminate the exhaust noise of Deaerator and optimize the environment.随州附近想过夜电话联系
In thermal cycle of thermal power plant and other industrial steam boilers, the condensate, desalted water deaerator After deaeration, the gas is not heated by the air exhaust pipe. In the process of removing non condensable gas, a large amount of noise will be generated to pollute the environment, and a part of steam will also be discharged together, which will cause a part of energy waste. Our company designed deaerator exhaust steam recovery energy-saving device is the latest energy-saving equipment, its main technical characteristics ? ：
?? 1 High heat and mass transfer efficiency, full heat and mass transfer 99% above 。
?? 2 Simple design, low failure rate ；
?? 3 Stable operation, safe and reliable, easy recovery of cooling water ；
?? 4 Non condensable gas is discharged into the atmosphere, reducing pipeline oxygen corrosion and prolonging the service life of equipment and pipeline;
?? 5 Eliminate noise and replace the original deaerator Exhaust muffler Optimizing the environment 。
2、 Working principle and process flow:
A. working principle
The upper part of the cylinder body of the deaerator residual steam recovery device is equipped with a water spray cooling pipe chamber, which is composed of a high-efficiency rotary jet ejector and a cooling pipe, and one side of the water spray cooling pipe chamber is connected with a cooling water inlet pipe. Under the spray cooling pipe chamber is the atomization space, below the atomization space is the heat and mass transfer components, and the steam distributor is under the heat and mass transfer components, and one side of the steam distributor is connected with the exhaust steam inlet pipe.
??? The new exhaust steam recovery energy-saving device is different from the ordinary deaerator residual steam recovery device. It condenses the three heat and mass transfer modes of atomization, water shower tray and liquid film into one, so it has high efficiency. It not only has great heat absorption function, but also has strong analysis ability for non condensable gas. The ordinary water spraying and falling film is replaced by strong atomization falling film, which increases the renewal degree of liquid film The liquid film can absorb a large amount of steam and increase the function of heat and mass transfer.
B. process flow
Cooling water is led from the main pipe of desalted water to the recovery unit from the inlet pipe chamber of the deaerator exhaust steam recovery device, and deaerator The exhaust steam from deaerator After sufficient mass and heat transfer, the non condensable gas is discharged from the upper waste gas outlet. The condensed water flows downward together with the atomized liquid film, and flows out from the water outlet to the drain tank.
