Description

Technical Field

[0001] This utility model relates to the technical field of ammonia water separation equipment, specifically to an ammonia water separation tank. Background Technology

[0002] Ammonia water is a low-boiling-point, highly volatile liquid that readily releases chlorine gas into the air, and ammonia gas itself is highly irritating. Currently, in industries such as chemical and non-ferrous metal smelting, desulfurization, dechlorination, and denitrification all generate large quantities of ammonia water. Direct discharge of this ammonia water not only causes serious environmental pollution but also wastes resources. Therefore, it is necessary to perform gas-liquid separation to separate and recover the ammonia gas from the ammonia water.

[0003] However, existing ammonia gas-liquid separators suffer from reduced ammonia vapor separation efficiency due to excessive foam buildup inside the tank. This decreases the separator's overall efficiency. Furthermore, the separated ammonia gas contains fine particulate impurities that, if not properly separated and filtered, result in suboptimal ammonia separation. Utility Model Content

[0004] In view of this, the present invention provides an ammonia water separator, which can achieve efficient and safe separation of ammonia water. Furthermore, the combination of a defoamer and filter elements can achieve efficient separation and purification of ammonia gas and solution, greatly improving the separation and purification effect of ammonia gas.

[0005] To solve the above-mentioned technical problems, this utility model provides an ammonia water separator, including a distillation tank connected to an ammonia water storage tank. A defoamer is rotatably installed inside the distillation tank, and an exhaust pipe is installed at the upper outlet of the distillation tank. A filter element is installed inside the exhaust pipe. This utility model can break up and dissolve the bubbles generated during the ammonia water gas-liquid separation process through the rotatably installed defoamer, greatly improving the distillation separation efficiency of ammonia water. The filter element can filter the separated ammonia gas and fine impurities, greatly improving the separation effect and efficiency of ammonia water.

[0006] The defoamer includes a rotating shaft rotatably mounted at the bottom of the distillation tank. The rotating shaft passes through the bottom of the distillation tank and is connected to an external drive source. A spiral stirring blade is provided on the outside of the rotating shaft located inside the distillation tank. This invention can rotate the rotating shaft and the spiral stirring blade together by rotating the output shaft of the drive source, thereby breaking and dissolving the bubbles generated during the ammonia-water separation process in the distillation tank, greatly improving the distillation efficiency.

[0007] The defoamer can also be a multi-layered baffle with through holes, spaced apart inside the distillation tank to form a defoaming structure.

[0008] The spiral stirring blades have multiple through holes, which allow the generated ammonia gas to pass through smoothly and effectively prevent the accumulation of air bubbles at the bottom of the spiral stirring blades, making it more convenient and efficient.

[0009] The filter element is a hemispherical arc plate structure with multiple filter holes. This invention can achieve efficient filtration of fine particulate impurities in the separated ammonia gas through the filter holes, ensuring the purity of the distilled ammonia gas.

[0010] The distillation tank has a hollow side wall and is equipped with a serpentine heating coil that is connected to an external heater. This invention can heat the distillation tank using the heat generated by the heater, which greatly improves the distillation efficiency of ammonia. The heating coil helps to increase the heat flow area and coverage, further improving the separation effect of ammonia.

[0011] The drive source is a servo motor, and the output shaft of the servo motor and the rotating shaft are connected and the power is transmitted through a reducer.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. This utility model can effectively eliminate the foam generated during the distillation of ammonia by setting a defoamer, avoid the foam from affecting the separation effect, and improve the separation purity. At the same time, the through hole design on the spiral stirring blade can further enhance the defoaming effect and make the liquid heat more evenly.

[0014] 2. The distillation tank of this utility model can be made of 316L stainless steel, which has excellent corrosion resistance and high temperature resistance, extending the service life of the equipment; the spiral stirring blades are made of Hastelloy C276 material, which further improves the durability of the equipment in highly corrosive environments.

[0015] 3. This utility model can effectively filter impurities and droplets in the separated gas by using a hemispherical arc plate filter element installed in the exhaust pipe, thereby improving gas purity and reducing the burden on subsequent processing equipment.

[0016] 4. This utility model can provide a larger heating area, more uniform heating, and higher thermal efficiency by setting a serpentine heating coil in the hollow side wall of the distillation tank compared with traditional heating methods, thereby further reducing energy consumption.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] like Figure 1-4 As shown: This embodiment provides an ammonia water separation tank, including a distillation tank 100 connected to an ammonia water storage tank. The distillation tank 100 is made of 316L stainless steel with a tank thickness of 8-12mm. A defoamer 200 is rotatably installed inside the distillation tank 100, and an exhaust pipe 300 is installed at the upper outlet of the distillation tank 100. A filter element 400 is installed inside the exhaust pipe 300. This utility model can break and dissolve the bubbles generated during the ammonia water gas-liquid separation process through the rotatably installed defoamer 200, which greatly improves the distillation separation efficiency of ammonia water. The gas can be filtered by the filter element 400 to filter the separated ammonia gas and fine impurities, which greatly improves the separation effect and efficiency of ammonia water.

[0024] According to one embodiment of the present invention, such as Figure 1-4As shown, the defoamer 200 includes a rotating shaft 210 rotatably mounted at the bottom of the distillation tank 100. The rotating shaft 210 is made of 45# steel and chrome-plated. The rotating shaft 210 passes through the bottom of the distillation tank 100 and is connected to an external drive source. The drive source is a servo motor, specifically a Delta ECMA-C20604RS, with a power of 400W and a rated speed of 3000rpm. The output shaft of the servo motor is connected to the rotating shaft 210 for transmission and power transmission through a reducer. A spiral stirring blade 220 is provided on the outer side of the rotating shaft 210 inside the distillation tank 100. The spiral stirring blade 220 is made of Hastelloy C276. This invention can rotate the rotating shaft 210 and the spiral stirring blade 220 together by rotating the output shaft of the drive source, thereby breaking down and dissolving the bubbles generated during the ammonia-water separation process in the distillation tank 100, greatly improving the distillation efficiency.

[0025] The defoamer 200 can also be a multi-layered baffle with through holes 221, which are spaced apart inside the distillation tank 100 to form a defoaming structure.

[0026] The spiral stirring blade 220 has multiple through holes 221 with a diameter of 5-8 mm and a center-to-center distance of 15-20 mm between adjacent through holes 221. The through holes 221 are arranged in an equilateral triangular array. This invention allows the generated ammonia gas to pass smoothly through the through holes 221 and can effectively prevent the accumulation of some air bubbles at the bottom of the spiral stirring blade 220, making it more convenient and efficient.

[0027] According to another embodiment of the present invention, such as Figure 1 and Figure 4 As shown, the filter element 400 has a hemispherical arc plate structure and multiple filter holes 410 are provided on the filter element 400. It is made of polytetrafluoroethylene and the filter hole 410 has a diameter of 0.5-1mm and a porosity of 35-45%. This utility model can achieve efficient filtration of fine particulate impurities in the separated ammonia gas through the filter holes 410 provided on the filter element 400, so as to ensure the purity of the distilled ammonia gas.

[0028] According to another embodiment of the present invention, such as Figure 1 and Figure 3As shown, the side wall of the distillation tank 100 is hollow and equipped with a serpentine heating coil, which is connected to an external heater. The serpentine heating coil is made of TP316 stainless steel with a diameter of φ18×2mm. The external heater is an electric heating thermal oil heater, specifically model Yancheng Suhai YLW-300MA, with a rated power of 300kW. This invention can heat the distillation tank 100 by the heat generated by the heater, which greatly improves the distillation efficiency of ammonia water. The heating coil helps to increase the heat flow area and coverage, further improving the separation effect of ammonia water.

[0029] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a temperature sensor and a pressure sensor are installed on the top of the distillation tank 100. The temperature sensor is an Omron E52-CA1D1 with a measurement range of 0-200℃ and an accuracy of ±0.5%FS. The pressure sensor is a Siemens QBE2003-P16 with a measurement range of -1 to 16 bar.

[0030] The bottom of the distillation tank 100 is equipped with a liquid outlet, and a solenoid valve is installed at the liquid outlet. The solenoid valve is an SMC VX2120-02-5DZ with a working pressure of 0.15-0.8MPa.

[0031] The distillation tank 100 is equipped with an external control cabinet, which contains a PLC controller, model Siemens S7-1214C DC / DC / DC. The PLC controller is electrically connected to the servo motor, external heater, temperature sensor, pressure sensor and solenoid valve respectively.

[0032] How to use this utility model:

[0033] First, it should be clarified that the separation tank involved in this utility model is mainly used for gas-liquid separation operations. This utility model takes the separation and purification of ammonia in ammonia water as an example to illustrate its usage method in detail. When ammonia water separation is required, the working principle and usage method are as follows:

[0034] Working principle:

[0035] When the ammonia water separator of this invention is in operation, ammonia water enters the distillation tank 100 from the ammonia water storage tank. The PLC controller starts the external heater (electric heating thermal oil furnace), which heats the ammonia water in the distillation tank 100 through the serpentine heating coil. At the same time, the PLC controller starts the servo motor, which drives the rotating shaft 210 and the spiral stirring blades 220 to rotate, stirring the ammonia water and making the ammonia water heated evenly.

[0036] During the heating process, the ammonia water gradually evaporates, and the generated ammonia gas rises to the upper part of the distillation tank 100. As the spiral stirring blades 220 rotate, they break up the generated foam through their surface and through holes 221, preventing the foam from entering the exhaust pipe 300 with the ammonia gas.

[0037] When ammonia gas is discharged through exhaust pipe 300, it passes through filter element 400 with hemispherical arc plate structure. The filter holes 410 on filter element 400 can trap droplets and impurities carried in ammonia gas. The purified ammonia gas is discharged from exhaust pipe 300 for further processing.

[0038] Temperature and pressure sensors monitor the temperature and pressure inside the distillation tank 100 in real time and transmit the signals to the PLC controller. The PLC controller automatically adjusts the power of the heater and the speed of the servo motor according to the set parameters to ensure that the separation process is carried out under optimal conditions.

[0039] After separation is complete, the PLC controller controls the solenoid valve to open, and the separated liquid is discharged from the outlet.

[0040] How to use:

[0041] Preparation: Check that all parts of the equipment are in good working order, ensure that the connection between the distillation tank 100 and the ammonia storage tank is unobstructed, and check that the power connection of each electrical control component is normal.

[0042] Parameter settings: Distillation temperature, stirring speed, separation time and other parameters can be set through the operation panel on the control cabinet. The PLC controller will automatically control the system according to the set parameters.

[0043] Start the equipment: Press the start button on the control cabinet, and the equipment will start working. Ammonia water will enter the distillation tank 100 from the ammonia water storage tank, and the heater and servo motor will start according to the set parameters.

[0044] Operation monitoring: During equipment operation, the temperature, pressure, and other parameters inside the distillation tank 100 are monitored in real time via the display screen on the control cabinet to ensure normal equipment operation. In case of any abnormality, the equipment will automatically alarm and take corresponding protective measures.

[0045] End of operation: When the separation process is complete or the equipment needs to be stopped, press the stop button on the control cabinet. The equipment will stop running according to the preset program. The heater will stop heating and the servo motor will stop rotating. After the temperature and pressure in the distillation tank 100 drop to a safe range, the solenoid valve will automatically open to discharge the separated liquid.

[0046] Equipment maintenance: Clean and maintain the equipment regularly, check the filter element 400 for blockage, and clean or replace it in time if blockage is found; check the lubrication of each rotating part and add lubricant regularly; check the working status of the electrical control components to ensure long-term stable operation of the equipment.

[0047] This invention enables efficient and safe separation of ammonia water using an ammonia water separator. Furthermore, the combination of a defoamer 200 and filter element 400 achieves efficient separation and purification of ammonia gas and solution, greatly improving the separation and purification effect of ammonia gas.

[0048] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0049] The above description is the preferred embodiment of this utility model.
