Description
The utility model relates to a kind of thermal deaerator, belongs to the improvement of low-pressure boiler water work.
Existing thermal deaerator adopts high-temperature water outlet, leaving water temperature is generally 104 ℃, for avoiding high-temperature water and steam through the boiler feed pump time corrosion pump housing, generally require delivery port and feed pump elevation difference 〉=7 meter, so that high-temperature water temperature in this section range ability descends to some extent, but cause equipment investment to increase like this, boiler room operation maintenance inconvenience.In addition, the boiler feed water temperature is higher, can increase its flue gas loss, reduces boiler efficiency, has increased the danger to the water generates boiling to cast iron gilled tube economizer again, and safe operation has been caused threat.
The purpose of this utility model is to provide a kind of low temperature water outlet, energy-conservation thermal deaerator realized.
The utility model is made up of deoxygenation head (1), water storage tank (2), wherein be provided with tube-in-tube heat exchanger (3) in the water storage tank (2), it is made up of sleeve pipe (301) that comprises interior pipe (301a) and outer tube (301b) and joint (302), during work, the interior pipe of heat exchanger (3) passes to normal-temperature water, outer tube passes to the high temperature deaerated water, the water of two kinds of temperature exchanges, through behind the LAP, deaerated water is reduced to about 60 ℃ from 104 ℃, then in boiler, thereby realize the purpose of low temperature water outlet.
The utility model concrete structure as shown in the figure, the interior pipe (301a) of sleeve pipe (301) and outer tube (301b) are supported by joint (302), be separated out normal temperature water cavity (302a) and deoxygenation water cavity (302b) between joint (302), the interior pipe (301a) of sleeve pipe (301) communicates with normal temperature water cavity (302a) and deoxygenation water cavity (302b) respectively with outer tube (301b).The radical of sleeve pipe (301) will require concrete selected according to water yield, cooling, after joint (302) was partitioned into normal temperature water cavity and deoxygenation water cavity, according to the requirement of heat exchange stroke, each water cavity also can be separated again, with control flow direction and mobile back and forth number of times, satisfy the requirement of leaving water temperature.
The utility model preferably will enter the soft water that deoxygenation head (1) carries out deoxygenation in order to the normal-temperature water that feeds interior pipe (301a), reached the purpose that reduces boiler feed temperature so on the one hand, on the other hand again preheating deoxygenation head water inlet, reached effect energy-conservation and that save land area.
Heat exchanger (3) can directly be placed or be fixed on water storage tank (2) bottom by modes such as welding screws.
For making the interior deaerated water of water storage tank (2) keep 104 ℃, to avoid overflowing oxygen and dissolve in once more, water storage tank also is provided with the device that seethes with excitement again in (2).
The utility model is owing to adopt tube-in-tube heat exchanger, normal-temperature water is not directly carried out heat exchange with the interior high-temperature water of water storage tank, realize the low temperature water outlet under the preceding topic that water temperature reduces in avoiding water storage tank, water storage tank delivery port and feed pump import mark difference is reduced to about 1.5 meters, require 〉=7 meters to reduce greatly than conventional, promptly make things convenient for installation to reduce construction investment about 70% again, also help management, the Operation and maintenance of boiler.The low temperature water outlet can further reduce the exhaust gas temperature of band economizer boiler on the other hand, thereby reduces heat loss due to exhaust gas more than 2%, has improved boiler efficiency, has saved fuel.Advantages such as that the utility model integrates is efficient, energy-conservation, safe and reliable, investment-saving are the desirable deaeration plants of miniature boiler.
