Description
Technical Field
[0001] This utility model relates to the technical field of testing equipment, and in particular to a performance testing device for a vaporized wet film humidifier. Background Technology
[0002] When humidification is needed, wet film humidifiers are commonly used. A wet film humidifier is an indoor humidification device. Under the action of gravity, water permeates downwards along the surface of the wet film and is absorbed by the highly absorbent wet film material, forming a uniform water film. When dry air passes through the pores of the wet film material, it exchanges heat with the moisture in the wet film. The water molecules fully absorb the heat from the air and vaporize, thereby increasing the humidity of the air and forming humid air.
[0003] With prolonged use, the performance of existing wet film humidifiers gradually declines due to changes in water and air quality. This necessitates cleaning and maintenance of the wet film. However, current technology does not test the performance of wet films after prolonged use or after cleaning, making it difficult to evaluate the humidification effect of the wet film. Utility Model Content The purpose of this utility model is to provide a performance testing device for a vaporized wet film humidifier, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: This utility model provides a performance testing device for an vaporized wet film humidifier, comprising: The air duct mechanism includes a chassis and a fan assembly. The chassis is provided with a test air duct. The fan assembly is connected to one end of the test air duct. The test air duct is provided with a fixture for detachably installing a wet film module, an inlet temperature and humidity sensor located upstream of the fixture, an outlet temperature and humidity sensor located downstream of the fixture, and an airflow meter for detecting the airflow of the test air duct. The water spraying mechanism includes a water spraying component and a water receiving component located at the tooling position. The water spraying component is located at the top of the wet membrane module, and the water receiving component is located at the bottom of the wet membrane module. The water spraying component is used to spray water onto the wet membrane module, and the water receiving component is used to receive water flowing through the wet membrane module.
[0005] The beneficial effects of this utility model's performance testing device for vaporized wet film humidifiers are: During use, the wet film module to be tested is installed in the tooling position, separating the two ends of the test air duct. During testing, with the fan assembly running, the air in the test air duct can flow completely through the wet film module from one end to the other. At the same time, water is sprayed onto the wet film module by the water spray assembly. The air volume of the test air duct is detected by an anemometer, and the air temperature and humidity on the inlet side of the wet film module are detected by an inlet temperature and humidity sensor, and the air temperature and humidity on the outlet side of the wet film module are detected by an outlet temperature and humidity sensor. Under the set air volume, the humidification capacity and humidification saturation efficiency of the wet film module are calculated by the difference between the air temperature and humidity on the inlet side and the air temperature and humidity on the outlet side, so as to evaluate the material properties of the wet film module and the effectiveness of cleaning and maintenance. In addition, the wet film modules before and after cleaning can be installed in the fixture position under the same inlet-side air temperature, humidity, air volume, and water spray conditions to obtain the humidification capacity and humidification saturation efficiency of the wet film modules before and after cleaning, and compare them. Alternatively, a new wet film module can be installed in the fixture position for testing to obtain the standard humidification capacity and humidification saturation efficiency, and compare it with the humidification capacity before cleaning to assess whether the wet film module needs cleaning. This vaporization type wet film humidifier performance testing device can flexibly and quickly test the humidification capacity and humidification saturation efficiency of the wet film module to evaluate its performance.
[0006] As a further improvement to the above technical solution, the water spraying mechanism further includes a circulation component, which is connected between the water spraying component and the water receiving component. The circulation component is used to sequentially transport the water received by the water receiving component back to the water spraying component.
[0007] As a further improvement to the above technical solution, the circulation component includes a circulating water tank, a circulating water pump, a flow meter, and a regulating water valve that are interconnected.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.
[0022] Currently, in existing wet film humidifiers, after a period of use, dirt accumulates in the wet film module 300 due to air and water quality factors, and alkaline components in the feed water also precipitate out, thus reducing the humidification performance of the wet film module 300. Currently, cleaning can generally restore the humidification capacity and remove some alkaline components. However, with prolonged use, cleaning cannot completely remove the dirt, and the humidifying material will age, reducing its water absorption. Therefore, it is necessary to test the humidification performance of the wet film module 300 to evaluate the effectiveness of cleaning and its humidification performance. However, current technology lacks a device that can quickly and flexibly test the humidification capacity of the wet film module 300 to evaluate its performance.
[0023] Furthermore, this utility model proposes a performance testing device for an vaporized wet film humidifier, which can simulate usage scenarios and flexibly and quickly test the humidification capacity and humidification saturation efficiency of the wet film module 300 in order to evaluate the performance of the wet film module 300.
[0024] like Figure 1 As shown, the performance testing device for the vaporized wet film humidifier of this utility model includes an air duct mechanism 100 and a water spraying mechanism 200.
[0025] Among them, such as Figures 1 to 4 As shown, the air duct mechanism 100 of this utility model includes a housing 110 and a fan assembly 120, as follows: Figure 1 As shown, the chassis 110 is provided with a test air duct 130, and a fan assembly 120 is installed at one end of the test air duct 130. The fan assembly 120 is used to provide power for the airflow in the test air duct 130.
[0026] like Figure 1 and Figure 2 As shown, the test air duct 130 of this embodiment is provided with a fixture position 131, an inlet temperature and humidity sensor 132, an outlet temperature and humidity sensor 133, and an air volume meter 134. The fixture position 131 is used to detachably install the wet film module 300. When the wet film module 300 is installed in the fixture position 131, the wet film module 300 can separate the two ends of the test air duct 130. Under the operation of the fan assembly 120, the air in the test air duct 130 can flow completely from one end to the other end through the wet film module 300.
[0027] Among them, the air volume meter 134 uses a composite Pitot tube sensor.
[0028] like Figure 1 and Figure 2As shown, the inlet temperature and humidity sensor 132 is located upstream of the fixture position 131 and is used to detect the air temperature and humidity before passing through the wet film module 300. The outlet temperature and humidity sensor 133 is located downstream of the fixture position 131 and is used to detect the air temperature and humidity after passing through the wet film module 300. The airflow meter 134 is used to detect the airflow of the test duct 130.
[0029] like Figure 1 As shown, the water spraying mechanism 200 of this utility model includes a water spraying component 210 and a water receiving component 220 disposed at the tooling position 131. The water spraying component 210 is located at the top of the wet film module 300 and is used to spray water onto the wet film module 300 so that the wet film module 300 forms a water film. The water receiving component 220 is located at the bottom of the wet film module 300 and is used to receive water flowing through the wet film module 300.
[0030] During testing, the wet film module 300 to be tested is installed in the fixture position 131. The wet film module 300 is sprayed with water by the water spraying component 210. At the same time, the fan component 120 is started. Under the set air volume, the humidification capacity of the wet film module 300 is calculated based on the difference between the air temperature and humidity before passing through the wet film module 300 and the air temperature and humidity after passing through the wet film module 300.
[0031] When conducting tests, this invention can also test the wet membrane module 300 in different states. For example, the wet membrane module 300 before and after cleaning can be installed in the tooling position 131 under the same inlet side air temperature and humidity, air volume and water spray conditions to obtain the humidification amount of the wet membrane module 300 before and after cleaning and compare them to evaluate the effect of cleaning and maintaining the wet membrane module 300.
[0032] Alternatively, the new wet film module 300 can be installed in fixture 131 for testing to obtain a standard humidification capacity, and compared with the humidification capacity of the wet film module 300 before cleaning, in order to assess whether the wet film module 300 needs to be cleaned and the water absorption of the material of the wet film module 300.
[0033] Among them, such as Figure 1 As shown, the water spraying mechanism 200 of this utility model also includes a circulation component 230, which is connected between the water spraying component 210 and the water receiving component 220. The circulation component 230 is used to sequentially transport the water received by the water receiving component 220 back to the water spraying component 210 to realize the recycling of water and achieve the effect of energy saving and emission reduction.
[0034] like Figure 1As shown, the circulation component 230 of this embodiment includes a circulation water tank 231, a circulation water pump 232, a flowmeter 233, and a regulating water valve 234 that are connected to each other. The water receiving component 220 includes a water receiving tank 221. The water receiving tank 221 is located below the wet film module 300 and is used to receive the water dripping from the wet film module 300. A drain port 2211 communicating with the circulation water tank 231 is provided at the bottom of the water receiving tank 221. The drain port 2211 is connected to the circulation water tank 231 through a drain pipe. The water spraying component 210 includes a water spraying pipe (not shown in the figure). The water spraying pipe is erected above the wet film module 300. The water spraying pipe is provided with a plurality of water spraying ports. The water spraying pipe is connected to the outlet end of the regulating water valve 234.
[0035] During use, the circulation water pump 232 pumps the water in the circulation water tank 231 to the water spraying pipe, and the water is sprayed onto the wet film module 300 through the water spraying pipe to form a water film on the wet film module 300. Then, the remaining water drops into the water receiving tank 221 and returns to the circulation water tank 231. Among them, the water spraying flow rate is adjusted by the flowmeter 233 and the regulating water valve 234.
[0036] Furthermore, as Figure 1 shown, the circulation water tank 231 of this embodiment is provided with a water temperature regulator 235. The water temperature regulator 235 is used to adjust the water temperature in the circulation water tank 231. The water temperature regulator 235 includes a heater and a cooler. The water is heated and raised in temperature by the heater, and the water is cooled and lowered in temperature by the cooler to cope with different test scenarios.
[0037] Regarding the installation method of the wet film module 300, as Figures 2 to 4 shown, the side wall of the test air duct 130 at the tooling position 131 of this embodiment is provided with an insertion port. The insertion port is provided with an openable and closable sealing plate 1311. The tooling position 131 is provided with an insertion slot (not shown in the figure) on the inner peripheral wall of the test air duct 130. The insertion slot is engaged with the edge of the wet film module 300. It can be understood that when the wet film module 300 needs to be disassembled and assembled, the sealing plate 1311 is opened, and the wet film module 300 is pulled out or inserted into the test air duct 130 from the insertion port. In the axial schematic diagram of the test air duct 130, the insertion slot is in a "C" shape, and the slot opening of the insertion slot is relatively communicated with the insertion port, so that the wet film module 300 can be inserted into the insertion slot through the insertion port, and the sealing performance of the installation of the wet film module 300 is improved, avoiding the phenomenon of air leakage between the wet film module 300 and the test air duct 130, which affects the accuracy of the test.
[0038] The air inlet of the fan component 120 of this embodiment is connected to the test air duct 130. It can be understood that the fan component 120 of this embodiment serves as an induced draft fan to provide negative pressure to the test air duct 130, so that the external air is sucked into the test air duct 130 to form a flowing wind.
[0039] In some embodiments, the fan assembly 120 is a variable frequency fan that adjusts its output power according to the testing requirements to adjust the air volume.
[0040] like Figures 2 to 4 As shown, the test air duct 130 of this embodiment includes an installation section 135, a first connecting section 136, a first test section 137, a second test section 138, and a second connecting section 139 that are detachably connected in sequence along the airflow direction. The test air duct 130 of this embodiment is formed by splicing multiple box sections, which facilitates manufacturing, maintenance, and repair.
[0041] Among them, such as Figure 2 As shown, tooling position 131 is located in installation section 135, inlet temperature and humidity sensor 132 is installed at the inlet of installation section 135, outlet temperature and humidity sensor 133 is installed in first test section 137, air volume meter 134 is installed in second test section 138, and the outlet of second connecting section 139 is connected to the air inlet of fan assembly 120. In this way, the corresponding housing section can be removed separately for maintenance and repair.
[0042] Furthermore, the diameter of the first connecting section 136 gradually decreases from the installation section 135 to the first test section 137, while the diameter of the second connecting section 139 gradually increases from the second test section 138 to the second connecting section 139. This can reduce the amount of material used and lower the cost.
[0043] In some embodiments, the tooling position 131 is provided with a weighing module (not shown) for detecting the weight of the wet film module 300, so that the wet film module 300 can be weighed before and after cleaning, and the amount of unwashable dirt on the wet film module 300 can be detected.
[0044] Specifically, the weighing module includes at least one pressure sensor located below the wet film module 300, which is used to detect the weight of the wet film module 300.
[0045] How to use the performance testing device for the vaporized wet film humidifier of this utility model: First, open the sealing plate 1311 and insert the wet film module 300 to be tested into the test air duct 130 through the insertion port, so that the wet film module 300 is inserted into the insertion slot through the insertion port, thereby improving the sealing of the wet film module 300 installation. Then close the sealing plate 1311. Start the circulating water pump 232 to pump the water in the circulating water tank 231 to the water spray pipe, and spray the water to the wet film module 300 through the water spray pipe so that the wet film module 300 forms a water film. Then the remaining water droplets fall into the water receiving tank 221 and return to the circulating water tank 231. The water spray flow rate is also adjusted by the flow meter 233 and the regulating water valve 234. Simultaneously, the fan assembly 120 is started and its power is adjusted. Under the set air volume, the humidification capacity of the wet film module 300 is calculated based on the difference between the air temperature and humidity before passing through the wet film module 300 and the air temperature and humidity after passing through the wet film module 300.
[0046] The wet membrane module 300 to be tested can be the wet membrane module 300 before and after cleaning, or a new wet membrane module 300, so as to obtain the humidification capacity and humidification saturation efficiency of the wet membrane module 300 before and after cleaning, and the humidification capacity and humidification saturation efficiency of the new wet membrane module 300, so as to evaluate the performance of the wet membrane module 300.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
