Description

Technical Field

[0001] This utility model belongs to the field of water treatment technology, and in particular relates to a defoamer testing device. Background Technology

[0002] Low-temperature vacuum evaporators are crucial equipment in water treatment processes. Their main function is to separate water from various solutions and prevent adverse side reactions of certain sensitive substances at high temperatures. The entire evaporation process does not produce crystallization or scaling, achieves high concentration rates, and the distilled water can be reused. However, foam generation is unavoidable during this evaporation process. Excessive foam can lead to instability in the low-temperature vacuum evaporator's operation during concentration, and may also cause material leakage and explosive boiling, severely affecting normal operation.

[0003] Adding defoamers can effectively control foam and improve the operating efficiency of low-temperature vacuum evaporators. However, extensive selection and testing of defoamers are required for different water qualities. Current defoamer selection techniques typically involve repeatedly starting and stopping the low-temperature vacuum evaporator on-site, adding different types of defoamers each time, recording the foam suppression effect, and cleaning the evaporator. Selection is then based on comparisons of the foam suppression effects of different types of defoamers. However, the process of starting and using low-temperature vacuum evaporators is complex, time-consuming, and energy-intensive, resulting in low efficiency and high cost for defoamer selection. Furthermore, using defoamers with unproven effects in experiments may cause problems for the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a defoamer testing device with a simple structure that can improve the efficiency of defoamer selection, reduce costs, and avoid the problems of low efficiency, high cost, and equipment wear and tear caused by directly selecting defoamers through a low-temperature vacuum evaporator.

[0023] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] An antifoaming agent testing device, such as Figure 1 The test chamber includes a reaction component 1, a collection component 2, and a vacuuming component 3. The reaction component 1 includes a reactor 11, which has an outlet 112A. The collection component 2 has a collection port 213A. The outlet 112A and the collection port 213A are sealed together. The reactor 11 and the collection component 2 form a sealed test chamber. The collection component 2 is sealed together with the vacuuming component 3. The vacuuming component 3 is used to evacuate the sealed test chamber.

[0029] If defoamer selection is performed directly through a low-temperature vacuum evaporator, the evaporator needs to be switched on and off multiple times. The process of starting and using a low-temperature vacuum evaporator is complicated, time-consuming, and energy-intensive, resulting in low efficiency and high cost for defoamer selection. Furthermore, adding defoamers with unproven effects for experiments may cause problems for the equipment.

[0030] This solution provides an antifoaming agent testing device. A reactor 11 and a collecting component 2 form a sealed testing chamber. The collecting component 2 is sealed to a vacuuming component 3, which evacuates the sealed testing chamber. By adding a water sample and antifoaming agent to the testing chamber and then evacuating it using the vacuuming component 3, the vacuum environment of a low-temperature vacuum evaporator can be simulated. This allows the water sample to be distilled at a lower temperature and collected in the collecting component 2. Simultaneously, the antifoaming effect of the antifoaming agent can be observed for selection. This solution has a simple structure, is easy to operate, improves the efficiency of antifoaming agent selection, reduces energy costs during selection, and avoids the low efficiency, high cost, and equipment wear problems associated with directly selecting antifoaming agents using a low-temperature vacuum evaporator.

[0031] As one implementation method, such as Figure 1The reaction component 1 also includes a mounting frame 12 for fixing the reactor 11.

[0032] As one implementation method, such as Figure 1 The reaction component 1 also includes a heater 13 for heating the reactor 11. The heater 13 is a water bath or an oil bath, etc., and the target operating temperature of the heater 13 is determined according to the operating temperature of the defoamer to be tested. Typically, the target operating temperature is 35℃-50℃.

[0033] As one implementation method, such as Figure 1 The reactor 11 has a feed inlet 112B, and a sealing plug 113 is provided at the feed inlet 112B. Thus, water sample and defoamer can be fed into the reactor 11 through the feed inlet 112B to react, and the sealing plug 113 seals the feed inlet 112B after the feeding is completed.

[0034] As one implementation method, such as Figure 1 The reactor 11 includes a test tube 111 and a first adapter 112. The first adapter 112 includes a connection port 112C for sealing the test tube 111, an outlet 112A, and a feed port 112B. Water is distilled out of the water sample in the test tube 111.

[0035] As one implementation method, test tube 111 is provided with graduations. This allows for convenient observation of foaming and foam suppression effects during the testing process.

[0036] As one implementation method, the capacity of test tube 111 is 50mL-200mL. During testing, the water sample added to test tube 111 shall not exceed 20% of the capacity of test tube 111.

[0037] As one implementation method, such as Figure 1 The collecting component 2 includes a piping assembly 21 and a collector 22. The piping assembly 21 includes an inner tube 211 and a condenser tube 212 disposed around the inner tube 211. The reactor 11 is sealed to the collector 22 through the inner tube 211. The condenser tube 212 contains a condenser. This facilitates the faster condensation of water vapor distilled from the water sample in the test tube 111 and entering the inner tube 211. Water can be used as the condenser.

[0038] As one implementation method, such as Figure 1 The condenser tube 212 is connected to an inlet tube 216 and an outlet tube 217. The refrigerant flows through the inlet tube 216, through the condenser tube 212, and then out through the outlet tube 217.

[0039] As one implementation method, such as Figure 1The piping assembly 21 also includes a second adapter 213. The inner tube 211 is sealed to the reactor 11 through the second adapter 213. The reaction component 1 includes n reactors 11. The second adapter 213 has n collection ports 213A. The n reactors 11 are connected to the n collection ports 213A in a one-to-one correspondence, where n is an integer greater than or equal to 2.

[0040] Specifically, the reaction component 1 includes n reactors 11. When n equals 2, a blank group with only water sample can be set up, and an experimental group with water sample and defoamer can be set up to compare the foaming situation with and without defoamer. When n is greater than 2, multiple experimental groups can be set up, and different defoamers can be added to different reactors 11 to improve experimental efficiency. The inner cavity tube 211 is connected to the reactors 11 through the second adapter 213. The second adapter 213 has n collection ports 213A. The n reactors 11 are connected to the n collection ports 213A one by one. Thus, multiple reactors 11 can share the inner cavity tube 211, condensation chamber tube 212, collector 22 and vacuum component 3, which is beneficial for weight reduction and cost saving.

[0041] As one implementation method, such as Figure 1 The piping assembly 21 also includes a third adapter 214, through which the inner tube 211 is sealed to the collector 22, and the vacuuming component 3 is sealed to the third adapter 214.

[0042] As one implementation method, such as Figure 1 The third adapter 214 is equipped with a valve 215, and the vacuum pumping component 3 is connected to the valve 215. The valve 215 is used to adjust the pumping capacity of the vacuum pumping component 3 and closes after the vacuum pumping component 3 stops working. Specifically, the valve 215 is a PTFE valve.

[0043] In one embodiment, the test tube 111, the first adapter 112, the sealing plug 113, the inner tube 211, the condensation tube 212, the second adapter 213, the third adapter 214, and the collector 22 are all made of glass. The joints between the test tube 111 and the first adapter 112, the first adapter 112 and the sealing plug 113, the first adapter 112 and the second adapter 213, the second adapter 213 and the inner tube 211, the inner tube 211 and the third adapter 214, and the third adapter 214 and the collector 22 are all ground and coated with lubricant (such as petroleum jelly, vacuum grease, etc.) to achieve a sealing effect.

[0044] As one implementation method, such as Figure 1The vacuum pumping component 3 includes a vacuum pump 31 and a vacuum rubber hose 32. The vacuum pump 31 is connected to the valve 215 via the vacuum rubber hose 32. The vacuum pump 31 is an intelligent vacuum pump, which can be automatically adjusted after setting the target vacuum level of the low-temperature vacuum evaporator, thus improving the stability and accuracy of the test. Typically, the adjustable negative pressure range of the intelligent vacuum pump is 0 to -80 kPa (displayed in real time on the digital panel).

[0045] As one implementation method, such as Figure 1 The test tube 111 is set vertically, the first adapter 112 is connected to the top of the test tube 111, the pipeline assembly 21 is set at an angle downward so that water vapor can be condensed and flow into the collector 22, the inlet pipe 216 is set near the bottom of the inner cavity pipe 211, and the outlet pipe 217 is set near the top of the inner cavity pipe 211 so that the refrigerant fills the condensation cavity pipe 212 and fully condenses the water vapor in the inner cavity pipe 211.

[0046] As one implementation method, such as Figures 1 to 3 The third adapter 214 includes a bent section and a vertical section. The inner tube 211 is connected to the bent section, the collector 22 is connected to the vertical section, and the valve 215 is located at the vertical section. Specifically, the bent section and the vertical section are separate structures connected to each other, or the bent section and the vertical section are an integral structure.

[0047] During testing, when n equals 2, one test tube 111 contains only water, while the other test tube 111 contains both water and defoamer. Valve 215 is opened, the target vacuum level of the intelligent vacuum pump is set, and the pump is turned on to check the airtightness and adjust to the target vacuum level. Refrigerant is allowed to circulate in the condenser tube 212, and heater 13 is turned on to the target operating temperature to simulate the low-temperature vacuum evaporation scenario of a low-temperature vacuum evaporator. The highest liquid level and stable foam height in both test tubes 111 are observed. Test tube 111 containing only water is used as a comparison to obtain the defoaming performance parameters of the defoamer in the other test tube 111. Multiple experiments are conducted, each time adding a different defoamer, and the defoaming performance parameters of different defoamers are compared to screen for suitable defoamers.

[0048] During testing, when n is greater than 2, one test tube 111 is filled with only water sample, while the other test tubes 111 are filled with water sample and different defoamers are added respectively. Valve 215 is opened, the target vacuum degree of the intelligent vacuum pump is set, the intelligent vacuum pump is turned on to evacuate and check the airtightness and adjust to the target vacuum degree, allowing the condenser to flow in the condenser tube 212, and the heater 13 is turned on to the target working temperature to simulate the low-temperature vacuum evaporation scenario of the low-temperature vacuum evaporator. The highest liquid level height and stable foam height in each test tube 111 are observed. The test tube 111 with only water sample is used as a comparison to obtain the defoaming performance parameters of the defoamers in the other test tubes 111. The defoaming performance parameters of different defoamers are compared to screen the defoamers.
