The utility model further enhances vacuum degree on the basis of the original desorbing and deoxidizing device so that the deoxidized water is deoxidized again. The utility model has the advantages of small size, low height, high vacuum degree of deoxidization, fully automatic operation and unattended operation, and the residual oxygen amount is less than or equal to 20 mg/l.
Description
The present invention relates to the multistage desorb degassing of a kind of boiler feedwater vacuum oxygen-eliminating device, belong to power boiler and general industry boiler feedwater deoxygenation.
Thin dirt of boiler or vimala operation, CO in the desorption deaerator combustion activity carbon pot water
2Increase on the contrary, deaerating effect is not good enough, and the task of top priority that increases the service life of more than 50 ten thousand boiler supply water deaeratings in the whole nation is demanded urgently and will be solved.
Purpose of the present invention is constantly aspirated the interior gas of degassing tower (9), Deadsorbing and oxygen removing repeatedly under higher vacuum and temperature conditions, and deoxygenation stablizing effect height can replace the advanced oxygen-eliminating device of existing Deadsorbing and oxygen removing, thermal de-aeration, vacuum dust cather fully.
Realize the technical program with following mode:
This equipment comprises: softened water tank (2), degassing tower (9), reacting furnace (12), compression pump (3) (4), feed pump (16), injector (5) (6), aspiration pump (8), control valve (7), electric heating circuit and pertinent instruments instrument are formed.
Degassing tower (9) is separated into two chambers, and the top between each chamber (10) and bottom (11) are intercommunicated.First compression pump (3) is squeezed into degassing gas-water separation in first degas chamber to the interior demineralized water atomizing of softened water tank (2), the residual oxygen water ejector (6) that has outgased in second compression pump (4) suction, first degas chamber jet atomization is once more squeezed into degassing gas-water separation in second degas chamber, and anaerobic water is squeezed into boiler by feed pump (16).
Figure (1) is a process chart of the present invention, and figure (2) is electrical heating temperature control circuit figure, and figure (3) is reacting furnace (a 12) structure chart.
Describe the enforcement of this programme in detail in conjunction with figure (1) (2) (3):
Interior the demineralized water of first compression pump (3) suction softened water tank (2) is suppressed injector (5) jet atomization gas-water separation in first degassing tower, between second compression pump (4) suction, first degassing in deoxidation residual oxygen water water jet pump (6) once more jet atomization squeeze into second outgas between in gas-water separation once more; Suction pump (8) constantly aspirates the interior gas of degassing tower (9), and top between each chamber (10) are communicated with gas, and bottom (11) are communicated with water, and the interior vacuum of running degassing tower (9) of aspiration pump (8) further improves the gas (O of extraction
2, CO
2) discharging sky in softened water tank (2).Be provided with heater (19) in the softened water tank (2), water level rises because the interior formation of the suction degassing tower (9) of two injectors (5) (6) and aspiration pump (8) high negative pressure water lightens, and controls the interior water level of degassing tower (9) with the interior vacuum of control valve (7) adjusting degassing tower (9) of suction pump (8) and goes up.
Circulation in during test running, circulating degasification in first compression pump (3) first injectors (5) first degas chambers; Circulating degasification once more between the degassing of second compression pump (4) second injectors (6) second, the gas of deviating from focuses on first degas chamber by reacting furnace (12) and aspiration pump (8) extraction; The interior electric heating tube of reacting furnace (12) (13) is heated to (200 ℃) combustion activity carbon (18), and activated carbon (18) is in combustion-supporting combustion activity carbon (18) deoxygenation down of oxygen, and oxygenless gas is extracted out by two injectors (5) (6) and participated in the air water jet atomization once more.
Electric heating circuit adopts bidirectional triode thyristor (KS) capacitance-resistance (RC) to trigger, and the operation of the high-power installation low-voltage of heating tube (13) small-power prolongs heating tube (13) service life, temperature indication adjusting apparatus (ST greatly
01) regulate temperature automatically by thermocouple (14), constant temperature low-voltage circuits for triggering (R when stopping make-up water
3), making to keep the deoxygenation temperature more than 200 ℃ in the reacting furnace (12), the cold and hot exchange volume of reacting furnace (12) multilayer is little, exchange effect height, aperture, multilayer fire bars (19) upper strata, hole is big, and the lower floor aperture is little, has avoided the obstruction in fire bars (19) hole.
Positive effect of the present invention:
Degassing tower (9) is separated into two more than the chamber, equipment volume is little, high insulating effect, compact conformation, a plurality of injectors (5) (6) ... the oxygenated water biography is connect the degassing improve deaerating effect greatly, the discharging of constantly bleeding of aspiration pump (8) not only improves the interior vacuum of degassing tower (9), also alleviate the power load of reacting furnace (12) and the consumption of activated carbon (18), reduce the deoxygenation unit consumption.
Native system compression pump (3) (4) pressure 〉=4kg, vacuum 〉=0.02MPa; Temperature in water temperature 〉=30 ℃, stove 〉=200 ℃, remaining oxygen≤0.02mg/L behind twice Deadsorbing and oxygen removing.
