The adjusting member 33 in this embodiment is a valve, and the compressed gas assembly 3 further includes a barometer 35 disposed between the valve and the air tap 34. Thus, the opening of the valve can be conveniently controlled according to the air pressure value required by each step to adjust the air pressure output by the air pump 31, and the air pressure value can be monitored by the air pressure meter 35 to ensure that proper air pressure can be output, and air bubbles or atomization phenomena which are easy to observe are generated.

Example 2:
as shown in fig. 2, a first embodiment of an inorganic membrane module detection method using the inorganic membrane module detection apparatus of embodiment 1 includes the steps of:
S1: completely immersing the inorganic membrane component into detection liquid in a detection container;
S2: the output air pressure of the air pump is regulated through a valve, and air with a first preset pressure value is filled into a water inlet of the inorganic membrane component for a first preset time;
s3: judging whether the inorganic membrane module is qualified according to whether uniform bubbles are generated on the side wall of the inorganic membrane module, if so, entering a step S4; if not, entering step S5;
S4: confirming whether the inorganic membrane module is qualified according to whether the uniform atomization phenomenon is generated on the side wall of the inorganic membrane module, if so, ending the current step; if not, entering step S5;
s5: defect locations of the inorganic membrane modules are determined.
Because only whether the bubbles generated by the inorganic membrane component are uniform or not is observed so as to judge whether the inorganic membrane is defective or not, a double judging mechanism is arranged, and the probability of misjudgment can be greatly reduced.
Specifically, the step S4 of confirming whether the inorganic membrane module is acceptable in the present embodiment specifically includes:
s41: closing the air pipe through the valve, and stopping filling the gas with the first preset pressure value into the inorganic membrane component;
S42: lifting the connecting piece from the detection liquid through the handle, and simultaneously taking out the inorganic membrane component from the detection container; at this time, due to capillary action, the detection liquid enters into the micropores of the inorganic membrane module and is adsorbed on the inorganic membrane module;
S43: the output air pressure of the air pump is regulated through a valve, and air with a second preset pressure value is filled into one end of the water inlet of the inorganic membrane component for a second preset time; thus, similar to the principle of generating bubbles in the detection liquid, the detection liquid adsorbed in micropores of the inorganic membrane module can be blown out to generate an atomization phenomenon on the surface of the inorganic membrane module, if the inorganic membrane module is qualified, uniform water mist can be formed on the surface of the inorganic membrane module because the micropores are not greatly different, and if the inorganic membrane module is defective, the area of the defect is far greater than that of the micropores, so that the water mist generated at the defect position is obviously different from other positions;
s44: judging whether the surface of the inorganic membrane component generates uniform atomization phenomenon, if so, confirming that the inorganic membrane component is qualified and stopping the current step; if not, the inorganic membrane module is completely immersed in the detection liquid in the detection container again, and the step S5 is performed.
Step S5 in this embodiment specifically includes: and filling gas with a third preset pressure value into the water inlet of the inorganic membrane module for a third preset time, slowly lifting the inorganic membrane module from the detection container, observing the condition of bubbles generated on the surface of the inorganic membrane module, marking the positions of non-uniform bubbles generated on the surface of the inorganic membrane module, and confirming the positions as defect positions, so that the inorganic membrane module can be maintained conveniently later. In this way, the defect judgment is performed on the inorganic membrane component for the third time, so that the probability of misjudgment is further reduced.
The first preset pressure value in this embodiment is 1KG/cm 2, the second preset pressure value is 0.5KG/cm 2, and the third preset pressure value is 2KG/cm 2.
The detection liquid in the embodiment is water, and the gas is air; of course, the detection liquid can also be a nontoxic, harmless and non-corrosive liquid such as ethanol, and the gas can also be helium or other inert gases, and it should be understood that, according to common knowledge, a person skilled in the art can use the gas to react with the detection liquid in a chemical manner, and the gas should be slightly soluble or insoluble in the detection liquid, so as to ensure that bubbles can be generated normally.
In this embodiment, by filling the pressurized gas into the inorganic membrane module, the gas passes through the micropores of the inorganic membrane module quickly and generates bubbles in the detection liquid, and since the pore diameter of the micropores of the inorganic membrane module is very small, the pores of the cracks are much larger than those of the micropores, and therefore, compared with the bubbles generated in the micropores, the bubbles generated by the cracks are larger, the rate is slower, and the bubbles are easier to separate, so that the method can be used as a reference for judging whether the inorganic membrane module has defects.
Example 3
The difference between this embodiment and embodiment 2 is only that the first preset pressure is 2KG/cm 2, the second preset pressure is 1.5KG/cm 2, and the third preset pressure is 3KG/cm 2.
Example 4
The difference between this embodiment and embodiment 2 or embodiment 3 is only that the first preset pressure is 1.5KG/cm 2, the second preset pressure is 1KG/cm 2, and the third preset pressure is 2.5KG/cm 2.
