The utility model discloses can wash the interior scale deposit of water pipe wall effectively, the cleaning efficiency is high to can avoid impurity oxidation scale deposit in condenser tube.
Description
Technical field
The utility model relates to a kind of cooling water pipe cleaning technique field, is particularly useful for the flusher of the cooling water recirculation system of metallurgical furnace furnace shell.
Background technology
Metallurgical furnace is all provided with furnace shell cooling water recirculation system, after this system is run for a long time, due to the calcium ions and magnesium ions enrichment in cooling water at water in-tube fouling, or the impurity in cooling water precipitates in water pipe, described sediment is mainly from cooling water tank, these all affect the cooling effect of furnace shell, thus have impact on the service life of metallurgical furnace.At present, it is all generally the flushing of leaning on cooling water to the process of cooling water pipe scaling, or beat cooling water pipe outer wall, scale forming matter is flushed to outside stove, but cooling water pipe is mostly provided with bend pipe, be difficult to removal of deposit by cooling water washing, even furnace shell will be cut when fouling is serious and clear up.
Summary of the invention
The purpose of this utility model is the shortcoming solving the easy fouling of above-mentioned furnace shell cooling water circulation water pipe content and non-easy cleaning, provide a kind of avoid impurity in cooling water pipe, be oxidized fouling and can fouling in rinse water tube wall effectively, metallurgical furnace furnace shell cooling water recirculation system flusher that cleaning efficiency is high.
The purpose of this utility model 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 the utility model metallurgical furnace furnace shell cooling water cycle water pipe 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 utility model 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
Schematic diagram when Fig. 1 is the utility model cleaning.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the cleaning liquid bath 4 that the utility model device is 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 delivery port of cooling water tank 7 and the water inlet of cooling water water inlet manifold 2 are provided with filter 8.
The method that the utility model flusher 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.
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, and be connected with water inlet 1a by cleaning fluid water inlet pipe 9, return flume is connected with CWR.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, and be connected with water inlet 1a by cleaning fluid water inlet pipe 9, return flume is connected with CWR.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.
