Object of the present invention is achieved through the following technical solutions:
A kind of metallurgical furnace furnace shell cooling water cycle water pipe flusher, the cleaning liquid bath that this device is provided with water pump, be interconnected by pipeline and return flume, cleaning, liquid bath is upper outside is connected to cleaning fluid water inlet pipe, the water inlet pipe of water pump is connected with cleaning fluid water inlet pipe, and the outlet pipe of water pump can be connected cooling water water inlet manifold water inlet with metallurgical furnace furnace shell cooling water cycle water pipe connects; Return flume is circumscribed with CWR, and the water inlet end of CWR is connected with the delivery port of metallurgical furnace furnace shell cooling water cycle water pipe.
The water inlet position height of metallurgical furnace furnace shell cooling water cycle water pipe of the present invention is lower than delivery port.The water inlet of cooling water water inlet manifold is provided with filter.Blowoff valve is provided with bottom metallurgical furnace furnace shell cooling water cycle water pipe.
The method that the present invention rinses metallurgical furnace furnace shell cooling water cycle water pipe is as follows: by the water inlet of cleaning fluid water inlet pipe access metallurgical furnace furnace shell cooling water cycle water pipe, start water pump, cleaning fluid in cleaning liquid bath is pumped in cooling water circulation water pipe, cleaning fluid circulates in cooling water circulation water pipe, fouling is cleaned, after cleaning, cleaning fluid is discharged from delivery port, gets back to return flume along CWR; Open blowoff valve, the fouling be deposited on bottom cooling water circulation water pipe is discharged; Described cleaning fluid be with hydrochloric acid and oxalic acid by weight be mixed with intermixture after, then by mixed liquor that mix reagent and water are mixed with by weight.
The present invention has prepared the cleaning fluid of the most applicable cleaning metallurgical furnace fouling, by custom-designed cleaning device, by cleaning fluid in cooling water pipe with the mode circulation flushing of low in and high out, improve flush efficiency; Cleaning terminates rear remaining liquid and is all back to return flume, does not cause cleaning fluid waste and the pollution to cooling water; The primary raw material of cleaning fluid used is hydrochloric acid and oxalic acid, and presses rational proportion preparation, and not only cost is low, and developing result is good; Bottom cooling water, arrange blowoff valve, the blowdown of discontinuity can reduce fouling after contamination precipitation in cooling water.Filter is set at cooling water tank, impurity can be reduced and enter furnace shell cooling water circulation water pipe.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention when cleaning.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, the cleaning liquid bath 4 that apparatus of the present invention are provided with water pump 3, be interconnected by pipeline and return flume 5, cleaning liquid bath 4 is circumscribed with cleaning fluid water inlet pipe 9, the water inlet pipe of water pump 3 is connected with cleaning fluid water inlet pipe 9, and the outlet pipe of water pump 3 can be connected with the water inlet 1a of metallurgical furnace furnace shell cooling water cycle water pipe 1.When metallurgical furnace furnace shell cooling water cycle water pipe 1 normally works, being the water inlet 1a by connecting cooling water water inlet manifold 2, cooling water being injected circulating water pipe Inner eycle, realizing the cooling to metallurgical furnace furnace shell.When cooling water cycle water in-tube fouling is more, when needing cleaning, cooling water water inlet manifold 2 is pulled down, connects cleaning fluid water inlet pipe 9 and carry out flushing work.After flushing completes, then cleaning fluid water inlet pipe is pulled down, again connect cooling water water inlet manifold.External CWR 6 on return flume 5, the water inlet end of CWR 6 is connected with the delivery port 1b of metallurgical furnace furnace shell cooling water cycle water pipe 1.In order to improve flush efficiency, the position height of water inlet 1a will lower than delivery port 1b, and usual water inlet is positioned at the bottom of metallurgical furnace furnace shell cooling water cycle water pipe, and delivery port is positioned at the middle part of metallurgical furnace furnace shell cooling water cycle water pipe.In order to prevent the sediment long time integration in cooling water pipe from forming fouling, bottom cooling water circulation water pipe, be provided with blowoff valve 10.Generate fouling in order to avoid impurity is oxidized in cooling water circulation water pipe, the water inlet of the delivery port machine cooling water water inlet manifold 2 of cooling water tank 7 is provided with filter 2.
The method that flusher of the present invention rinses metallurgical furnace furnace shell cooling water cycle water pipe is as follows: by the water inlet 1a of cleaning fluid water inlet pipe 9 snap joint access metallurgical furnace furnace shell cooling water cycle water pipe, start water pump 3, cleaning fluid in cleaning liquid bath 4 is pumped in cooling water circulation water pipe 1, cleaning fluid circulates in cooling water circulation water pipe, cleans fouling.Cleaning fluid and fouling is utilized to react, by removal of deposit.Described cleaning fluid be with hydrochloric acid and oxalic acid by weight 1 ︰ 1 ~ 3 ︰ 1 be mixed with intermixture after, then by mix reagent and the water mixed liquor that is mixed with of 1 ︰ 5 ~ 2 ︰ 5 by weight, cleaning fluid pH is 4 ~ 7.
Described fouling mainly composition is calcium ions and magnesium ions sediment and iron rust, and following reaction generation compound soluble in water occurs cleaning fluid:
Mg
2++2Cl
-＝MgCl
2；
Ca
2++2Cl
-＝CaCl
2；
Fe
3++3Cl
-＝FeCl
3。
Because the existence of above-mentioned reaction is eliminated or inhibits the solidification of fouling in cooling water pipe, improve the cooling effect of cooling water, improve the service life of metallurgical furnace simultaneously.
After cleaning, cleaning fluid is discharged from delivery port 1b, gets back to return flume 5 along CWR 6; Open blowoff valve 10, the fouling be deposited on bottom cooling water circulation water pipe is discharged.
For 20 square metres of vertical metallurgical furnaces, it is one group that its furnace shell cooling water is generally provided with 4 branch roads, cleaning fluid water inlet pipe 9 is connected with water inlet 1a, return flume is connected with CWR, cleaning fluid is prepared in cleaning liquid bath, hydrochloric acid and oxalic acid are mixed and made into intermixture by weight 1:1, and intermixture is prepared by weight 1:5 with water and obtained cleaning fluid, controls the PH of cleaning fluid 4 ~ 7.Observe the color of cleaning fluid and the changes in flow rate of each branch road in return flume after opening water pump, rinse 10 ~ 15 minutes.
For 20 square metres of horizontal metallurgical furnaces, it is one group that its furnace shell cooling water is generally provided with 1 branch road, cleaning fluid water inlet pipe 9 is connected with water inlet 1a, return flume is connected with CWR, cleaning fluid is prepared in cleaning liquid bath, hydrochloric acid and oxalic acid make intermixture by weight 1:2, and intermixture is prepared by weight 1:5 with water and obtained cleaning fluid, controls the PH of cleaning fluid 4 ~ 7.Observe the color of cleaning fluid and the changes in flow rate of this branch road in return flume after opening water pump, washing time is generally 5 ~ 10 minutes, if circling water flow rate is comparatively large in flushing process, also can shorten washing time.
