Detailed Description
The invention is further described with reference to the drawings and the detailed description. For better description, the deep steel pipe section is divided into a front section and a rear section.
As shown in fig. 1, embodiment 1 of the present invention includes a bracket 1, a storage tank 2, a filter 3, a centrifugal pump 4, and a pipeline.
The filter 3 and the centrifugal pump 4 are arranged on a shelf at the lower part of the bracket 1. For the convenience of movement, universal wheels can be arranged at the bottom of the bracket 11.
The liquid inlet of the filter 3 is connected with a pipeline which is used for being connected with the lower exhaust port of the water pump 5 through a liquid outlet valve 52. The liquid outlet of the filter 3 is connected with the centrifugal pump 4 and the liquid inlet 22 of the storage tank 2 in sequence through pipelines.
One-way ball valves are arranged at the liquid outlet 21 and the liquid inlet 22 of the storage tank 2.
When the water pump is cleaned, the positions of the flanges of the inlet and the outlet of the water pump 5 are closed, the closing mode can be determined according to the respective conditions of the water pump, and the embodiment adopts a blind plate blocking mode, namely, the inlet and the outlet are closed by the flange pipe block. Opening a ball valve of a liquid outlet 21 of the storage tank 2, enabling dilute hydrochloric acid to enter a water pump 5, setting the water pump 5 to rotate at a low speed to dissolve scales formed in an impeller and the interior of the water pump 5, then opening a valve 52 of the liquid outlet, enabling turbid liquid with scale residues to flow into a filter 3 for filtering, enabling filtered liquid after primary solid-liquid separation to be subjected to secondary separation through a centrifugal pump 4, enabling the liquid to return to the storage tank 2, and enabling the liquid to enter self-cleaning circulation again to achieve the purpose of recycling the dilute hydrochloric acid.
The structure of the embodiment 1 is characterized by simplicity, low manufacturing cost, and the water pump system for flushing slag and recycling water is often in composite deposition due to the complex scale components, and after dilute hydrochloric acid enters, Mg (OH) in the composite deposition can be removed2、CaCO3The precipitate is treated by chemical reaction, hardened scale is discharged along with the hardened scale, the proportion of solid components in turbid liquid discharge is high, the loss of dilute hydrochloric acid is not very high through solid-liquid separation of the filter 3 and the centrifugal pump 4, and generally, the water pump can be cleaned up after self-cleaning circulation for 2-3 hours. For the slag flushing water pump for non-circulating water utilization, the main component of the scale is Mg (OH)2、CaCO3Precipitation, high loss of dilute hydrochloric acid with self-cleaning cycle, late cleaning of MgCl2、CaCl2A large amount of the waste water is remained in the circulating liquid, and the cleaning time of the water pump with the same specification needs more than 8 hours.
Therefore, in order to improve the utilization rate of the diluted hydrochloric acid and reduce the cleaning time of the water pump, the structure of the filter 3 of the embodiment 1 is improved in the embodiment 2.
As shown in fig. 2, the filter 3 includes a housing 31, a liquid inlet 32, a liquid outlet 33, a vapor outlet 34, a filter screen, a filter plate, a heating device 37, a feed port, and a settling tank 39. The inside filter screen 351, last filter 361, lower filter 362, lower filter 352 from top to bottom of casing 31 respectively, the filter screen be the stainless steel otter board, the purpose is to filter solid-state sediment, the filter plate be the slabby filter core. A heating device 37, which may be an acid-proof electric heating tube, is arranged between the upper filter plate 361 and the lower filter plate 362. The electromagnetic valve is arranged at the liquid outlet 33 of the filter 3 and is linked with the liquid outlet valve 52 arranged at the water pump 5, namely, the electromagnetic valve and the liquid outlet valve are opened or closed simultaneously, and the circulation time of the dilute hydrochloric acid in the water pump 5 is consistent with the treatment time of the discharged liquid in the filter 3. The top end of the filter 3 is provided with a steam outlet 34, the steam outlet 34 is sequentially connected with the liquid inlet 22 of the storage tank 2 through a pipeline, the dilute hydrochloric acid is volatile acid, and the hydrochloric acid and the water vapor can be sent back to the storage tank 2 together through heating. In an optimized scheme, a one-way condensation pipe is arranged between the steam outlet 34 and the liquid inlet 22 of the storage tank 2. The charge door is connected with the charging tank through a pipeline with a one-way valve, the charging tank is not shown in figure 2, and the charging tank can charge materials under the action of gravity without a liquid pump. The contents of the feed are determined for the scale treatment liquid and the scale components, in this example, the scale treatment liquid is diluted hydrochloric acid, and the target is MgCl2、CaCl2Therefore, there is an upper feeding port 381 above the upper screen 351 for adding Ca (OH)2To remove MgCl2. A lower feed port 382 is provided above the lower screen 352 for the addition of Na2CO3To remove CaCl2. At the bottom of the filter 3 there is a settling tank 39 with a blow-off valve, the purpose of which is to deposit Mg (OH)2Precipitation and CaCO3And (4) precipitating. The turbid liquid enters the shell 31 through the liquid inlet 32, and solid particles are trapped on the upper filter screen 351, the upper filter plate 361,The lower filter plate 362 has a slow filtering speed, increases the evaporation time of hydrochloric acid in the turbid liquid, also reduces water flow impact on the sedimentation tank 39, and is beneficial to sedimentation of sediment.
It should be noted that while the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the invention.
