[0025] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in this application. Obviously, the embodiments described are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] The present application provides a chemical machine pump cooling water circulation system, which can improve the machine pump cooling water circulation system in the device, optimize the graded utilization of water resources, and reduce the amount of sewage generated.

[0027] An embodiment of the chemical pump cooling water circulation system in the present application includes:

[0028] High-level cooling water collection tank, pH detector, first pipeline pump, second pipeline pump, main pipeline, branch pipeline, float level switch, cleaning liquid tank, fluosilicic acid tank, aging tank and clarification tank;

[0029] High-position cooling water collection tank: Installed on the roof platform, the high-position water collection tank replaces the conventional bottom water collection tank, and the cooling water can flow freely from top to bottom into each pipe trough.

[0030] pH detector: can accurately monitor the pH of cooling water in the high-level cooling water collection tank in real time.

[0031] A pipeline pump is a single-suction, single-stage or multi-stage centrifugal pump with a vertical structure. Its inlet and outlet are aligned and have the same diameter, similar to a section of pipe. Due to its unique structural design, the pipeline pump can be installed anywhere in the pipeline and is suitable for a variety of materials, including stainless steel, cast iron, and engineering plastics. The uses of pipeline pumps include boosting and circulation. Regarding boosting, when the pipeline pressure is insufficient, the pipeline pump can be installed in the pipeline to increase the system pressure and ensure smooth fluid delivery. Regarding circulation, the circulating pump acts to pump water or other fluids from the pool or tank, circulate through the pipeline, and then return, thus achieving the circulation operation of the system.

[0032] Float level switch: uses the floating of the float to control the action of the switch. When the liquid level of the measured medium changes, the float will move accordingly, thereby driving the magnet inside the switch to move, thereby changing the on-off state of the circuit.

[0033] Cleaning liquid tank: The main function of the cleaning liquid tank is to store cleaning liquid. In industrial production, tank cleaning can quickly and thoroughly clean the dirt and impurities inside the tank, keep the production environment clean and hygienic, ensure production safety, and improve production efficiency.

[0034] Fluorosilicic acid tank: During the production of phosphoric acid, a large amount of fluosilicic acid is produced. The fluosilicic acid tank is used to collect, recycle and store fluosilicic acid.

[0035] Aging tank: Aging tank is a gravity sedimentation equipment used for solid-liquid separation. For example, in industrial production, by controlling conditions such as temperature and humidity, the aging process of raw materials is promoted and the quality of raw materials is improved.

[0036] Clarifiers: Clarifiers are used for liquid clarification and solid-liquid separation. Liquid enters the tank through an inlet and remains within it for a period of time. During this period, suspended solid particles in the liquid settle to the bottom of the tank due to gravity, forming a sedimentation layer. Clear liquid then flows out of the tank's upper or side outlets, achieving both liquid clarification and solid-liquid separation.

[0037] In the embodiment, a water outlet is provided on one side of the high-level cooling water collection tank 01, the water outlet is connected to a water outlet pipe, and the pH detector 011 is provided on the water outlet pipe;

[0038] The first pipeline pump 013 and the second pipeline pump 014 serve as cooling water circulation pumps and are arranged on the other side of the high-level cooling water collection tank 01;

[0039] The float liquid level switch 012 is arranged on the side of the high-level cooling water collection tank 01;

[0040] The cleaning liquid tank A02, the cleaning liquid tank B03, the fluorosilicic acid tank A04, the fluorosilicic acid tank B05, the aging tank A06, the aging tank B07, the clarification tank A08, the clarification tank B09, the clarification tank C10 and the clarification tank D011 are collected into the main pipeline 015 through the branch pipeline 016;

[0041] The cleaning liquid tank A02, the cleaning liquid tank B03, the fluorosilicic acid tank A04, the fluorosilicic acid tank B05, the aging tank A06, the aging tank B07, the clarification tank A08, the clarification tank B09, the clarification tank C10 and the clarification tank D011 are connected to the high-level cooling water collection tank 01 through the main pipeline 015.

[0042] In this embodiment, when the liquid level in the high-level cooling water collection tank is lower than the set value, the system automatically replenishes process water under the control of the main control room; cooling water from the cleaning liquid tank A02, cleaning liquid tank B03, fluorosilicic acid tank A04, fluorosilicic acid tank B05, aging tank A06, aging tank B07, clarification tank A08, clarification tank B09, clarification tank C10, and clarification tank D011 enters the pipeline pump and is transported to the high-level cooling water collection tank 01; when each tank area needs to be replenished with cooling water, the cooling water in the high-level cooling water collection tank returns to each pump by gravity and then returns to each tank area through each pump. When the mechanical seal of the pump is damaged and a leak occurs, the cooling water in the high-level cooling water collection tank 01 is introduced into the ditch through the outlet and transported to the extraction system for consumption.

[0043] In this embodiment, the provision of the high-level cooling water collection tank 01 improves the cooling water circulation system of the machine pump in the device, optimizes the graded utilization of water resources, reduces the amount of sewage generated, and realizes the recycling of cooling water.

[0044] A large amount of sewage will be generated during the production process. The sewage is cooled by industrial water and then discharged directly into the ditch, causing a waste of water resources. Therefore, it is necessary to set up a cooling water collection tank.

[0045] In an optional embodiment, the high-level cooling water collection tank 01 is installed on the roof platform to collect and store cooling water;

[0046] The high-level water collecting tank replaces the conventional bottom water collecting tank, and the cooling water can flow freely from top to bottom into each pipe trough;

[0047] The high-level cooling water collection tank 01 has a diameter of 1.8m, a height of 2m, and a volume of 6m 3 ;

[0048] The high-level cooling water collection tank 01 is made of waste pipes, so that the waste pipes can be recycled;

[0049] The high-level cooling water collection tank 01 is treated with anti-corrosion inside and outside to extend the service life of the high-level cooling water collection tank 01;

[0050] The high-position water collecting tank replaces the conventional bottom water collecting tank, and the cooling water can flow freely from top to bottom into each pipe trough.

[0051] In this embodiment, the installation of the high-level cooling water collection tank 01 improves the cooling water circulation system of the machine pump in the device, optimizes the hierarchical utilization of water resources, effectively reduces the production water consumption, reduces the generation of sewage, alleviates the water balance pressure, and realizes the recycling of cooling water.

[0052] In an optional embodiment, the first pipeline pump is a main pipeline pump 015, and the second pipeline pump is a branch pipeline pump 016. The main pipeline is a pipe with a diameter of Φ57*3.5 and a material of 316L, and the branch pipe is a pipe with a diameter of Φ32*3 and a material of 316L.

[0053] The inlet and outlet diameters of pipeline pumps are the same and they can be installed at any position in the pipeline; the main uses of pipeline pumps include pressurization and circulation.

[0054] In terms of boosting, when pipeline pressure is insufficient, pipeline pumps can be installed on the pipeline to increase system pressure and ensure smooth fluid delivery. In terms of circulation, pipeline pumps are often used in systems such as air conditioning circulation, factory water purification circulation, and boiler circulation. Through the function of the circulation pump, water or other fluids are pumped out of the pool or tank, circulated through the pipeline, and then returned, thus realizing the circulation operation of the system.

[0055] In addition, pipeline centrifugal pumps are also suitable for conveying clean water and other liquids with physical and chemical properties similar to clean water. They are suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden sprinkler irrigation, fire fighting pressurization, long-distance transportation, HVAC refrigeration cycle, bathroom hot and cold water circulation pressurization and equipment matching.

[0056] In this embodiment, the application of pipeline pumps plays an important role in improving the efficiency of the system and ensuring the delivery of cooling water to various tanks.

[0057] In industrial production, in order to monitor the acidity of water in real time, the setting of a pH detector is indispensable.

[0058] In an optional embodiment, the pH detector 011 is connected to the phosphoric acid production main control room through the DCS system to monitor the pH value of water quality in real time.

[0059] A water outlet is provided on one side of the high-level cooling water collection tank 01, the water outlet is connected to a water outlet pipe, and the pH detector 011 is provided on the water outlet pipe;

[0060] The pH meter 011 has a fast response speed and can accurately measure the pH value of the solution in a short time. This helps to monitor the pH value changes of the solution in real time during the production process and adjust the process parameters in time.

[0061] In this embodiment, the pH detector 011 is used to monitor and control the pH of the chemical reaction during the production process. By monitoring the pH of the reaction solution in real time, the process parameters can be optimized and the product quality and output can be improved.

[0062] In an optional embodiment, cooling water enters the pipeline and is transported to the high-level cooling water collection tank 01 through a pipeline pump. The float liquid level 012 switch sets a safety liquid level. When the liquid level is lower than the set value, process water is automatically replenished through DCS system monitoring.

[0063] The float level switch 012 controls the on / off state of the circuit by changing the cooling water level, thereby achieving automatic control of the cooling water level. The float level switch 012 does not require an external power supply, has a simple structure, and operates reliably, making it suitable for controlling liquids of various properties or pressure and temperature conditions.

[0064] In this embodiment, the setting of the float liquid level switch 012 ensures that the cooling water in the high-level cooling water collection tank 01 is at a safe liquid level in real time. Process water can be automatically replenished through DCS system monitoring and control, thereby improving the cooling water circulation system.
