Description
One, technical field:
The utility model relates to a kind of deoxygenator, particularly relates to the vacuum dust cather that a kind of injection boiler is used.
Two, background technology:
Along with the needs of the application of injection boiler, movable injection boiler is because its flexible characteristic number of applications is more and more, but its removal of home is frequent just, and on-the-spot to connect workload big, former its work characteristics of fixedly thermal deaerator incompatibility.For guaranteeing the requirement of injection boiler to oxygen level, a large amount of work has been done by how tame manufacturer, and the modes such as sponge iron deoxygenation apparatus, vacuum dust cather of having used are carried out deoxygenation.Wherein, existing vacuum dust cather is to arrive the deaeration in condenser head by working shaft, separate for carrying out oxygen under the-0.097MPa in vacuum tightness through atomization, deaerated water is the boiler of feeding water in water collector concentrates on header tank, separated oxygen is attracted through ball-and-seat to spill box by vacuum pump, thereby reaches the purpose of deoxygenation.
At present, the problem that exists is existing sponge iron deoxygenation apparatus or vacuum dust cather, and oxygen level is many more than 200ppb in operational process, can't reach injection boiler water supply and contain the requirement of oxygen smaller or equal to 50ppb, add chemical agent in addition for touching the mark and handle, caused very big waste.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of vacuum dust cather that injection boiler water supply contains the oxygen requirement that directly reaches is provided.
Its technical scheme is: mainly be made up of working shaft, deaeration in condenser head, header tank, vacuum pump and spill box, working shaft is communicated with header tank, be provided with the deaeration in condenser head in the header tank, spill box is communicated with by vacuum pump and header tank, separated oxygen is attracted to spill box by vacuum pump, in the deaerated water in header tank the boiler of feeding water, described deaeration in condenser head is communicated with the outlet of injector, the inlet of injector is communicated with nitrogen tube and water inlet pipe.
Wherein, described deaeration in condenser head is made up of main jet head bracket and rotatable head cartridge, and the outlet of main jet head and time shower nozzle upwards.
In addition, preferable scheme is that the spacing of main jet head and time shower nozzle is 600mm, and the injection flow rate of each shower nozzle under 0.4-0.6Mpa is 0.6-1m3/h, requires design sprinkler quantity according to service discharge.
Described nitrogen tube connects Nitrogen plant or nitrogengas cylinder, has avoided interpolation S-WAT polluted water.
Working process of the present utility model is will treat that by injector the water of deoxygenation acutely mixes with nitrogen, arrives the deaeration in condenser head, carries out in water gas delivery in vacuum tightness under-the 0.097MPa through atomization.Because the dissolved gas with various shows the pressure component difference of formation at water droplet in the water, its velocity of separation is also different, thereby existing the separating out from the water droplet surface of nitrogen reduced a part pressure, thereby has improved oxygen velocity of separation and degree, thereby reaches the purpose that improves deaerating effect.
The beneficial effects of the utility model are: adopt the vacuum dust cather of 15t/h to carry out laboratory experiment, pass through laboratory experiment, the oxygen-containing water of 4mg/l can be reduced to below the 30ppb under molten nitrogen concentration 2mg/l and move, the deoxygenation rate reaches 99.25%, reaches the injection boiler oxygen containing requirement of supplying water fully; In addition, not only avoid interpolation S-WAT polluted water, and adopted nitrogen to significantly reduce production cost, improved working efficiency.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is structural representations of deaeration in condenser head of the present utility model.
Five, embodiment:
In conjunction with the accompanying drawings 1 and 2, the utility model will be further described:
Its technical scheme is: mainly by working shaft 1, deaeration in condenser head 2, header tank 3, vacuum pump 4 and spill box 5 are formed, working shaft 1 is communicated with header tank 3, be provided with deaeration in condenser head 2 in the header tank, spill box 5 is communicated with header tank 3 by vacuum pump 4, separated oxygen is attracted to spill box by vacuum pump, deaerated water is the boiler of feeding water in header tank, improvement is that deaeration in condenser head 2 is communicated with the outlet of injector 6, the inlet of injector 6 is communicated with nitrogen tube and water inlet pipe, nitrogen tube connects Nitrogen plant or nitrogengas cylinder 7, has avoided interpolation S-WAT polluted water, uses injector and adds nitrogen automatically, water acutely mixes with nitrogen, and is nitrogen gas dissolved even more rapidly.
Wherein, deaeration in condenser head 2 is made up of main jet head bracket 8 and rotatable head cartridge 9, the outlet of main jet head and time shower nozzle upwards, the spacing of main jet head and time shower nozzle is 600mm, the injection flow rate of each shower nozzle under 0.4-0.6Mpa is 0.6-1m3/h, requires design sprinkler quantity according to service discharge.Wherein, the shower nozzle water spraying direction is a upper-spraying type, descends after the process that the water droplet process rises again, and has increased the residence time of water smoke under vacuum state.And the diameter of shower nozzle is 6mm, the water droplets refinement more of feasible ejection.
Working process of the present utility model is will treat that by injector the water of deoxygenation acutely mixes with nitrogen, arrives the deaeration in condenser head, carries out in water gas delivery in vacuum tightness under-the 0.097MPa through atomization.Because the dissolved gas with various shows the pressure component difference of formation at water droplet in the water, its velocity of separation is also different, thereby existing the separating out from the water droplet surface of nitrogen reduced a part pressure, thereby has improved oxygen velocity of separation and degree, thereby reaches the purpose that improves deaerating effect.
In addition, the 15t/h vacuum dust cather of the utility model design carries out laboratory experiment, by the inside experiment, the oxygen-containing water of 4mg/l can be reduced to 30ppb and once move under molten nitrogen concentration 2mg/l.The deoxygenation rate reaches 99.25%, reaches the injection boiler oxygen containing requirement of supplying water fully.
