Description
Technical Field
The application relates to the technical field of water dephosphorization, in particular to a high-pressure water dephosphorization system.
Background
In the production process of the steel pipe, the steel pipe is easy to oxidize when in a high temperature state, and a layer of compact iron scale (phosphorus skin) is formed on the surface of the steel pipe. If this scale cannot be removed before rolling, they are pressed into the strip surface by the rolls during rolling, affecting its surface quality. The residual iron scale can also accelerate the abrasion of the roller and reduce the service life of the roller. Therefore, before billet rolling, it is necessary to remove the scale on the surface. The method of removing scale (high-pressure water dephosphorization) by using the mechanical impact force of high-pressure water is currently the most popular and effective method.
The traditional high-pressure water dephosphorization process is that water enters a high-pressure water dephosphorization system from a main water supply pipe, and a nozzle is arranged at the tail end of the scale of the high-pressure water dephosphorization system. Under the action of the nozzle, the high-pressure water forms a fan-shaped water beam with a large impact force and is sprayed to the surface of the steel pipe. Under the action of the high-pressure fan-shaped water jet beam, the iron scale is quenched and contracted and is peeled off from the steel pipe parent metal, so that the iron scale is removed.
The water tank of the conventional high pressure water dephosphorization system is provided with a water overflow outlet for the excess water to overflow when the water entering the water tank exceeds a water level threshold. And the water sprayed by the descaling nozzle directly flows away after the surface of the steel pipe is dephosphorized. During the whole water dephosphorization process, the water flow is kept unchanged regardless of the water dephosphorization effect. From the above, in the conventional high-pressure water dephosphorization system, the water resource is not fully utilized in the whole high-pressure water descaling process, and the water resource is easily wasted.

Detailed Description

Referring to fig. 1, a schematic structural diagram of a high-pressure water dephosphorization system according to an embodiment of the present application is shown in fig. 1, where the system includes: the first gate valve 1, the second gate valve 2, the tank water level control valve group 3, the first tank 4, the second tank 5, the first pipe pump 6, the second pipe pump 7, the third pipe pump 8, the first filter 9, the second filter 10, the high-pressure water pump 11, the high-pressure check valve 12, the high-pressure flow rate adjustment valve 13, the water recovery device 14, the phosphorus weighing device 15 (not shown in the figure), the water flow direction control device 16, the fourth pipe pump 17, the liquid level controller 18, the fifth gate valve 19, and the sixth gate valve 20.

The water output from the water outlet end of the first water tank 4 firstly enters the first filter 9 by the action of the first pipeline pump 6, and then enters the high-pressure water pump 11 after being filtered. It should be noted that the water entering the first filter 9 may have a certain water pressure by the first pipe pump 6, and then smoothly enter the high-pressure water pump 11 after being filtered. The high-pressure one-way valve 12 is respectively connected with the water outlet end of the high-pressure water pump 11 and the water inlet end of the high-pressure flow regulating valve 13, and the water outlet end of the high-pressure flow regulating valve 13 is connected with a dephosphorizing nozzle.
In the actual production process, the water level control valve group 3 cannot accurately control the water amount entering the first water tank 4, so that the water tank 4 is provided with a water overflow end. Since the overflowed water does not have any water pressure, a second pipe pump 7 is provided. The water overflow end of the first water tank 4 is connected with the water inlet end of the second pipeline pump 7, and water overflowed from the water overflow end enters the second pipeline pump 7 and is output by a certain water pressure. The water outlet end of the second pipeline pump 7 is connected with the water inlet end of the second water tank 5, and water output from the water outlet end of the second pipeline pump 7 enters the second water tank 5, so that one of the functions of the second water tank 5 is collection and storage of overflowed water of the first water tank 4. The water outlet end of the second water tank 5 is connected with the water inlet end of the water level control valve group 3, the water outlet end of the second water tank 5 is provided with a second gate valve 2 with the water level control valve group 3, and the second gate valve 2 is in a closed state when water in the first gate valve 1 is normally supplied.
In the application, the second water tank 5 can also recycle the water after dephosphorization. The water recovery device 14 is provided corresponding to the dephosphorization nozzle, and the water recovery device 14 is provided with a plurality of water recovery holes. After the dephosphorization of the steel pipe is completed by the water sprayed from the dephosphorization nozzle, the water flows into the pipeline communicated with the water recovery holes through the water recovery holes and flows out from the water outlet end of the water recovery device 14. The water outlet end of the water recovery device 14 is connected with the water inlet end of the third pipeline pump 8, the water outlet end of the third pipeline pump 8 is connected with the water inlet end of the second filter 10, the second filter 10 filters the water after the dephosphorization operation, and then the water is conveyed into the second water tank 5 through the water outlet end of the second filter 10.
In an exemplary embodiment, a water flow direction control device 16 and a fourth pipeline pump 17 are further disposed between the second filter 10 and the second water tank 5, a water outlet end of the second filter 10 is connected with a water inlet end of the water flow direction control device 16, a first water outlet end of the water flow direction control device 16 is connected with a water inlet end of the fourth pipeline pump 17, a water outlet end of the fourth pipeline pump 17 is connected with a water inlet end of the second water tank 5, and a second water outlet end of the water flow direction control device 16 is connected with a water inlet end of the second filter 10. After the high-pressure water dephosphorization operation, the water quality may change, such as PH. The water flow control means 16 is therefore provided for the purpose of detecting the quality of water output from the second filter 10, and if the quality of water is not satisfactory, the water is returned to the second filter 10 for filtration, at which point a suitable treatment agent may be added.
As shown in fig. 2, the water flow direction control device 16 in this embodiment includes a water quality detector 161, a third gate valve 162 and a fourth gate valve 163, the water inlet end of the water quality detector 161 is connected to the water outlet end of the second filter 10, the water outlet ends of the water quality detector 161 are respectively connected to the third gate valve 162 and one end of the fourth gate valve 163, the other end of the third gate valve 162 is connected to the water inlet end of the fourth pipeline pump 17, the other end of the fourth gate valve 163 is connected to the water inlet end of the second filter 10, and the detection module of the water quality detector 161 is respectively electrically connected to the third gate valve 162 and the fourth gate valve 163. If the water quality detector 161 detects how the water quality of the water delivered from the second filter 10 is required, the third gate valve 162 is controlled to be opened, the fourth gate valve 163 is controlled to be closed, and the water is delivered to the fourth pipe pump 17 and then to the second tank 5. If the water quality is not satisfactory, the water quality detector 161 controls the third gate valve 162 to be closed, the fourth gate valve 163 to be opened, and the water flows back to the second filter 10 again.
In the embodiment, in order to control the water consumption during the dephosphorization operation and ensure the full utilization of the water, the water flow and the water pressure are controlled according to the dephosphorization effect. A phosphate weighing device 15 is thus provided at one end of the water recovery device 14. The phosphorus weighing device 15 is respectively and electrically connected with the water tank water level control valve bank 3 and the high-pressure water pump 11, and the phosphorus weighing device 15 is used for controlling the water tank water level control valve bank 3 and the high-pressure water pump 11 according to the weight of phosphorus weighed in unit time. Since steel pipes are generally standard components, the dephosphorization operation time for one steel pipe can be divided into a plurality of uniform operation time periods, and each operation time period is identical. If a steel pipe has good dephosphorization effect, the weight of the removed phosphorus should be in a weight range, so that the weight of the removed phosphorus should be in a weight range with small fluctuation in a working period. Therefore, if the weight of the phosphorus chips obtained in a certain working period is far smaller than the minimum weight in the historical working period, it can be judged that the phosphorus removal effect is not good. At this time, the phosphate weighing device 15 controls the water tank water level control valve group 3 to deliver more water into the water tank 1, and controls the high-pressure water pump 11 to increase the water pressure. If the weight of the phosphorus chips obtained in a plurality of operation time periods is stable, the water flow and the water pressure can be properly reduced, and if the weight of the phosphorus chips removed in one operation time period after the reduction is not changed greatly, the phosphorus removal operation can be carried out according to the current water flow and the water pressure.
In one exemplary embodiment, as shown in fig. 3, the water recovery device 14 includes a water filtering steel plate 141, a supporting base 142 and a pushing plate 143, the supporting base 142 is fixedly connected with the water filtering steel plate 141, the phosphorus weighing device 15 is disposed at one end of the water filtering steel plate 141, the pushing plate 143 is disposed at the other end of the water filtering steel plate 141, and the pushing plate 143 is movably connected with the water filtering steel plate 141. The push plate 143 pushes the removed scales into the phosphate weighing device 15 after the end of one working period, and the phosphate weighing device 15 weighs the scales removed in the previous working period.
In another embodiment, as shown in fig. 4, the water recovery device 14 includes a first support base 144 and a second support base 145 of the water filtering steel plate 141, the first support base 144 and the second support base 145 are respectively disposed at two ends of the water filtering steel plate 141, the first support base 144 is movably connected with the water filtering steel plate 141 through a rotating shaft, an air cylinder 146 is disposed between the second support base 145 and the water filtering steel plate 141, the air cylinder 146 is respectively connected with the second support base 145 and the water filtering steel plate 141, and the phosphorus weighing device 15 is disposed at one end of the water filtering steel plate 141 corresponding to the first support base 144. After an operation time period is finished, one end of the water filtering steel plate 141 is jacked up by the air cylinder 146, and the other end of the water filtering steel plate 141 can rotate due to the rotating shaft arranged between the water filtering steel plate and the first supporting base 144, so that the water filtering steel plate 141 is in an inclined state, at the moment, due to the action of gravity, removed scales can slide into the phosphate weighing device 15, and the phosphate weighing device 15 weighs the scales.
It should be noted that, since the initial time of entering the flake weighing device 15 carries some moisture, the flake weighing device 15 needs to wait for a preset period of time until the weighed flake weight is at a stable value before weighing the flakes.
In this embodiment, a liquid level controller 18 is disposed on top of the second water tank 5, and the liquid level controller 18 is electrically connected to the first gate valve 1 and the second gate valve 2 respectively. If the water collected in the second water tank 5 reaches the preset value, a certain water level is reached in the second water tank 5, and the liquid level controller 18 detects that the first gate valve 1 is directly controlled to be closed, the second gate valve 2 is opened, and the water in the second water tank 5 is utilized, so that the water is reused.
