AI Technical Summary
The brine pipeline is gradually scaled during operation, resulting in the brine transmission volume that cannot meet production needs. The existing technology is difficult to effectively solve this problem, resulting in the need to start a second pressurization pump or perform artificial disassembly and descaling operations, which consumes manpower and time.
A salt water pipe scaling treatment system is designed, and the switching connection between the sub-pipe and the reaction tank or the main pipe is achieved through the conversion head. Use brine or acid to pass into the sub-pipe that has not yet been scaled, adjust the brine outflow or acid reflux to maintain the brine flow transmitted by the pipe, and perform pickling and descaling of the entire pipe if needed.
By using the sub-pipe to maintain the brine flow, the energy consumption of the dual pumps is reduced; when the pipeline is severely scaled, acid reflux is used to achieve descaling of the entire pipeline, avoiding the process of artificially dismantling the pipeline and saving time and manpower.

Abstract
Description
Technical Field
[0001] The present application relates to the field of pipeline scaling treatment, and in particular to a brine pipeline scaling treatment system. Background Art
[0002] The primary brine process usually passes alkali liquid into a reaction tank with brine to remove elements such as calcium and magnesium contained in the brine. After the reaction, the brine flowing out of the reaction tank is transmitted to the gas-water mixer distribution station through a pipeline, and then several distribution pipelines connected to the gas-liquid mixer distribution station pass the brine to the pressurized gas dissolving tank for further purification of the brine. However, as the running time increases, the pipeline between the output end of the booster pump and the gas-water mixer distribution station will gradually scale, resulting in the brine transmission volume of the pipeline being unable to meet the current production needs. Therefore, it is necessary to start a second booster pump to maintain production. However, as the scaling worsens, even dual pump operation still cannot meet production needs. At this time, the technicians will stop the machine and perform subsequent descaling operations on the pipeline by manually disassembling the pipeline, which is not only labor-intensive but also time-consuming.

[0030] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0031] In the prior art, the brine pipeline scaling treatment system includes a reaction tank 1 and a main pipeline 2. Figure 1 .
[0032] The reaction tank 1 is mainly used to remove elements such as calcium and magnesium to carry out the alkalization reaction of the salt water. A reaction feed pipe 10 is provided on one side of the side wall of the reaction tank 1 near its bottom. Alkali liquid such as sodium hydroxide is introduced into the reaction tank 1 through the reaction feed pipe 10. A discharge port is provided on the other side of the side wall of the reaction tank 1 near the bottom for discharging the salt water in the reaction tank.
[0033] The main pipeline 2 has an input end connected to the discharge port of the reaction tank. A first regulating valve 11 is provided at the main pipeline 1 near the discharge port. The first pump 20 and the second pump 21 are arranged in parallel in the main pipeline 2. That is, the brine in the reaction tank 1 can be pumped into the main pipeline 2 by the operation of the double pumps. The first pump 20 and the second pump 21 are both pressurized pumps. Among them, the main pipeline 2 is provided with a second regulating valve 22 near the input end of the second pump 21, which is used to control the input flow of the second pump 21. The main pipeline 2 is provided with a third regulating valve 23 near the output end of the second pump 21, which is used to control the output flow of the second pump 21. The first regulating valve 11, the second regulating valve 22 and the third regulating valve 23 can all be butterfly valves. The output end of the main pipeline 2 is divided into a first outlet pipeline 30 and a second outlet pipeline 32. The first outlet pipeline 30 and the second outlet pipeline 32 are respectively connected to the gas-water mixer distribution table.
[0034] The salt water flows to the gas-water mixer distribution station through the main pipeline 2, specifically: the first regulating valve 11 is controlled, the first pump 20 is started, and the salt water in the reaction tank 1 is pumped into the main pipeline 2, and then flows through the first outlet pipeline 30 and finally leads to the gas-water mixer distribution station. When the main pipeline 2 between the output end of the first pump 20 and the gas-water mixer distribution station is gradually scaled and the salt water flow rate pumped by the first pump 20 to the gas-water mixer distribution station cannot meet the production demand, the second regulating valve 22 and the third regulating valve 23 can be controlled, and the second pump 21 can be started to allow the salt water to flow into the second outlet pipeline 32 to maintain the salt water flow rate transmitted by the pipeline.
[0035] In order to overcome the problem that the operation of the dual pumps in the prior art cannot meet the brine flow requirements of pipeline transmission, please refer to Figure 2-Figure 3 , the improvement method adopted in the embodiment of the present application is as follows:
[0036] The top of the reaction tank 1 is provided with an acid washing feed pipe 12 and an acid solution reflux pipe 13 respectively.
[0037] A secondary pipe 33 is added beside the main pipe 2, and brine or pickling pipe is introduced into the secondary pipe 33 which has not yet been scaled. One end of the secondary pipe 33 is movably connected to a conversion head 35, and the secondary pipe 33 is switchably connected to the reaction tank 1 or the first outlet pipe 30 through the conversion head 35. The conversion head 35 can be a titanium elbow. A blind flange 36 is provided at the output end of the first outlet pipe 30.
[0038] When the brine in the reaction tank 1 is transported through the main pipeline 2, the conversion head 35 is usually connected to the first outlet pipeline 30 through the blind flange 36. By adjusting the blind flange 36, brine is passed into the secondary pipeline 33 to maintain the brine flow rate required for pipeline transmission. At this time, the second pump 21 is turned off to reduce the energy consumption of the dual pump operation.
[0039] Once all pipelines are seriously fouled and need to be stopped for maintenance, the conversion head 35 is disconnected from the first outlet pipeline 30 and then connected to the acid return pipeline 13, so that all pipelines can be acid-washed in the future. The specific method of acid washing is: the output end of the auxiliary pipeline 33 is connected to the discharge end of the second outlet pipeline 32, and an outlet valve 34 is provided between the connection end and the gas-water mixer distribution table.
[0040] The specific process of pickling the pipeline is as follows: after the pickling liquid is passed into the reaction tank 1 through the acid liquid feed pipe 12, the scale layer in the reaction tank 1 can be removed. Then, the first regulating valve 11 is controlled to make the acid liquid in the reaction tank 1 flow to the main pipe 2, so as to pickle and descale the pressure pump, valve, etc. provided in the main pipe 2. Among them, the acid liquid flowing through the second outlet pipe 32 can flow back to the auxiliary pipe 33 when the outlet valve 34 is closed, so as to pickle and descale the auxiliary pipe 33. Then, it flows through the conversion head 35 and the acid liquid reflux pipe 13, and flows to the reaction tank 1, thereby achieving the removal of the scale layer in the pipeline, without the need to manually dismantle the pipeline for pipeline cleaning.
[0041] In order to further detect the removal of the scale layer in the pipeline, a sampling valve 24 is provided near the input end of each booster pump of the main pipeline 2 for sampling. The removal of the scale layer in the pipeline is determined by detecting whether the sampled material is acidic.
[0042] Based on the above embodiments, the advantages of this application are:
[0043] The present application adds a secondary pipe 33 to the side of the main pipe 2 through a conversion head 35, and the conversion head 35 can realize the switching connection between the secondary pipe 33 and the reaction tank 1 or the main pipe 2. At the same time, the present application also connects the output end of the secondary pipe 33 with the discharge end of the second outlet pipe 32 and sets an outlet valve 34 at the pipe to adjust the brine to flow out of the main pipe 2 or the acid to flow back to the secondary pipe 33. In this way, when the scale layer in the pipeline makes the double pump operation unable to meet the production demand, the brine is introduced into the secondary pipe 33 that has not yet scaled to maintain the brine flow rate transmitted by the pipeline, which can greatly reduce the energy consumption of the double pump operation. When all pipes are severely scaled and need to be stopped for maintenance, the acid flowing to the main pipe 2 is used to flow back to the secondary pipe 33 to achieve descaling of all pipes, avoiding the manual removal of the pipes for descaling, saving time and manpower.
