As improvement, described de-salted water storage tank is connected with final purge zone by pipeline, and pipeline is provided with the one-way cock that de-salted water flows to final purge zone.
Improve, the described 1# scrubbing unit steam heater corresponding with final purge zone is set to close down again.
Finally, in described pickling unit, in the existing two groups of water-cooling systems of stove cooling section, one group of closedown is set.
Compared with prior art, the utility model has the advantage of: increase reclamation of condensate water conduit and electric conductivity detector, every for pickling unit platform heater steam condensation water collection is entered de-salted water storage tank, be used for final purge zone de-salted water on the one hand to supplement, to save de-salted water, the opposing party, by the high temperature of steam condensate self, makes it be mixed in de-salted water and improves wash-down water temperature, substitute steam heating, with steam saving; Close one group of water-cooling system, weaken annealing furnace cooling section cooling power, improve steel band own temperature, utilize steel band waste-heat pickle solution, alleviate steam heater load, with steam saving.The utility model is reasonable in design, and can reduce de-salted water and supplement and steam consumption, favourable energy-conserving and environment-protective, are not only applicable to the energy-conservation of pickling machine group, also can be widely used in all kinds of steam that utilizes as the manufacture field of heating source.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of integrated steam system for pickling unit, pickling unit comprises the electrolysis that sets gradually one section 1, electrolysis two section 2, 1# scrubbing unit 3, nitration mixture one section 4, nitration mixture two section 5, rinse one section 6, 2# scrubbing unit 7, final purge zone 8, dryer section 9 and accordingly each steam heater 10, electrolysis one section 1, electrolysis two section 2, 1# scrubbing unit 3, nitration mixture one section 4, the one end of the steam heater 10 that nitration mixture is two section 5 is connected to electrolysis one section of circulation tank 1.1 by pipeline, electrolysis two sections of circulation tanks 2.1, 1# scrubbing unit circulation tank 3.1, nitration mixture one section of circulation tank 4.1, nitration mixture two sections of circulation tanks 5.1, electrolysis one section 1, electrolysis two section 2, 1# scrubbing unit 3, nitration mixture one section 4, the steam heater 10 that nitration mixture is two section 5 has additional the reclamation of condensate water conduit for collecting every platform steam heater 10 water of condensation, gathered by gathering tube 11, two sections are divided into after reclamation of condensate water conduit gathers, respectively with de-salted water circulation tank 13, effluent pit 16 is connected, the gathering tube 11 of reclamation of condensate water conduit is provided with electric conductivity detector 12 and every section be in charge of corresponding valve is installed, when water of condensation specific conductivity meets processing requirement, the first valve 14 being discharged into effluent pit 16 is closed automatically, the second valve 15 being simultaneously discharged into de-salted water storage tank 13 is opened automatically, when water of condensation specific conductivity does not meet processing requirement, the first valve 14 being discharged into effluent pit 16 is opened automatically, the second valve 15 being simultaneously discharged into de-salted water storage tank 13 is closed automatically, de-salted water storage tank 13 is connected with final purge zone 8 by pipeline, pipeline is provided with the one-way cock 17 that de-salted water flows to final purge zone 8, the available steam condensate of so every platform steam heater 10 utilizes himself overpressure, be collected into de-salted water hold-up vessel 13, without the need to increasing extra pressure again, collect the water of condensation obtained, through electric conductivity detector 12 detect qualified after, be collected in de-salted water storage tank 13 by pipeline, and detect defective after, effluent pit 16 is disposed to by pipeline, water of condensation is supplemented for final purge zone 8 de-salted water on the one hand, to save de-salted water, the opposing party is by the high temperature of steam condensate self, make it be mixed in de-salted water and improve wash-down water temperature, substitute steam heating, with steam saving, in order to weaken annealing furnace cooling section cooling power, improve steel band own temperature, make full use of steel band self waste heat, under the prerequisite that technique allows, one group of closedown is set by existing for stove cooling section in pickling unit two groups of water-cooling systems, and 1# scrubbing unit 3 and the corresponding steam heater 10 of final purge zone 8 are set to close down, make steel band self remain on comparatively high temps like this, reduce thermal source loss, utilize steel band waste-heat pickle solution, alleviate steam heater load, with steam saving.
