Description

Technical Field

Background

Environmental monitoring (environmental monitoring) refers to determining environmental quality (or pollution level) and its trend by measuring representative values of factors affecting environmental quality. In order to obtain accurate data, environmental monitoring meters are typically required to be placed near factories, construction sites, etc., and multiple items of data are monitored simultaneously, such as air humidity, VOCs, dust particles. In order to prevent flying insects and dust particles from directly entering the environment monitor and affecting the data accuracy of the environment monitor, the environment monitor generally adopts a sealed box body, and then an air extraction probe is arranged outside the sealed box body. Wherein the air extraction probe is used for providing air samples outside the box for each monitoring device inside the box.

However, this design has a problem in that if the humidity of the air is too high, when the air sample is transported too long in the environmental monitor and the flow rate is slow, dust in the air sample gradually combines with the moisture of the air sample, which causes dust particles to gradually adhere to each other and form agglomerates. Due to the large weight of the agglomerates, problems with the deposition of agglomerates in the pipe can occur. When the deposited caking is excessive, the pipeline inside the box body is blocked, which can influence the accuracy of data monitored by each monitoring device.

To sum up, when existing environmental monitor has air humidity too big, dust particle can adhere into the caking in gas transmission pipeline, leads to the pipeline to block up, influences other gas monitoring devices can't monitor the problem of accurate data.

Detailed Description

The utility model is further elucidated below in conjunction with the accompanying drawings.

The orientations referred to in the present specification are all based on the orientations of the environmental monitoring instrument in normal operation, and are not limited to the orientations in storage and transportation, but only represent relative positional relationships, and not absolute positional relationships.

As shown in fig. 1-5, an environment monitoring instrument comprises a monitoring probe 1 and a sealing box body 2, wherein a humidity detection piece 21, a dust detection piece 22 and an air detection box 23 are installed in the sealing box body 2, a condensing box 3 is arranged between the air detection box 23 and the dust detection piece 22, a plurality of refrigerating sheets 31 are arranged in the condensing box 3, the refrigerating sheets 31 comprise a low-temperature surface 311 and a high-temperature surface 312, and the high-temperature surface 312 of the refrigerating sheets 31 is in heat conduction connection with the side wall of the condensing box 3; an air inlet hose 11 is arranged between the humidity detection part 21 and the monitoring probe 1, and the humidity detection part 21, the dust detection part 22, the condensing box 3 and the air detection box 23 are sequentially connected through a sealing pipeline. The working principle of the scheme is as follows: first, the monitoring probe 1 acquires an air sample, and sends the air sample to the humidity detecting member 21 through the air intake hose 11, and the moisture content of the air sample is detected by the humidity detecting member 21. Then, the air sample reaches the dust detecting member 22 along the sealed pipe, and the content of dust particles in the air sample is detected by the dust detecting member 22. After passing through the humidity detecting member 21 and the dust detecting member 22, the air sample starts to slow down, which causes the dust particles to be more easily combined with the moisture, so that the dust particles are adhered to each other to form a lump, and are adhered to the inner wall of the sealed pipe. For this purpose, the present solution introduces a condensation tank 3. In operation, the cooling fins 31 in the condensing box 3 will transfer the temperature in the condensing box 3 to the high temperature surface 312 by the low temperature surface 311, and then the high temperature surface 312 will dissipate heat through the side wall of the condensing box 3. The temperature in the condensing tank 3 gradually decreases by the cooling fin 31. Finally, after the air sample enters the condensing box 3, moisture in the air sample is affected by low temperature and gradually combined in the condensing box 3 to form water drops, so that the dehumidifying operation of the air sample is completed. In the process of passing through the condensing box 3, dust particles carried by the air sample can be intercepted by water drops, so that the dust removal work is also completed.

To sum up, in order to reduce the influence of humidity and dust particles on the gas detection, we need to detect the humidity and dust particles, then treat the moisture and dust, and finally introduce the air sample into the gas detection part for detection. Therefore, the air sample acquired by the monitoring probe 1 first passes through the humidity detecting member 21 and the dust detecting member 22. In order to prevent the air sample from caking caused by combination of dust particles and moisture in the long-distance transmission process and the problem of blocking a sealed pipeline, the air sample needs to be dehumidified and dedusted. Therefore, the condensing box 3 is introduced, the cooling plate 31 is used for cooling the condensing box 3, and when the temperature in the condensing box 3 is reduced to a certain range, the moisture in the air sample starts to condense into dew, so that the dehumidifying work is completed. Meanwhile, dust particles in the air sample can be intercepted by water drops, so that the dust particles are fixed, and the dust removal of the air sample is completed. So far, the moisture and dust particle content in the air sample is greatly reduced. When the air sample enters the air detection box 23, the influence of moisture and dust particles on each gas detection part in the air detection box 23 is greatly reduced, so that the accuracy of the monitoring data of each gas detection part is ensured.

The cooling fin 31 in this embodiment is a semiconductor cooling fin. The semiconductor refrigerating sheet, also called thermoelectric refrigerating sheet, has the advantages of no need of any refrigerant, continuous operation, no pollution source, no rotating component, no turning effect, no sliding component, no vibration and noise during operation, long service life and easy installation.

As shown in fig. 4, since the cooling fin 31 transfers heat only from the low temperature surface 311 to the high temperature surface 312, the cooling efficiency of the low temperature surface 311 is greatly reduced if the high temperature surface 312 is not cooled. For this purpose, a U-shaped heat pipe 32 is installed on the outer wall of the condensation box 3, a part of the U-shaped heat pipe 32 is located between the condensation box 3 and the sealed box 2, another part of the U-shaped heat pipe 32 is located outside the sealed box 2, and a heat dissipation fin 33 is installed at one end of the U-shaped heat pipe 32 away from the condensation box 3. The U-shaped heat pipe 32 transfers heat on the side wall of the condensing box 3 from the inside of the sealed box 2 to the outside, and then the heat radiating area is increased by the heat radiating fins 33, which greatly accelerates the heat radiating speed of the high temperature surface 312 and also accelerates the temperature dropping speed in the condensing box 3. In addition, the design avoids arranging a ventilation port on the sealed box body 2 to assist the cooling fin 31 to dissipate heat, and the tightness of the sealed box body 2 can be ensured only by adding a sealing layer between the U-shaped heat pipe 32 and the sealed box body 2.

As shown in fig. 4, the high temperature surface 312 transfers heat to the side wall of the condensation box 3, and then the side wall of the condensation box 3 transfers the received heat to the U-shaped heat pipe 32, which increases the propagation path of the heat and affects the heat dissipation efficiency. For this purpose, the side wall of the condensing box 3 is provided with a plurality of through holes, the refrigerating plate 31 is installed in the through holes, the high temperature surface 312 is in heat conduction connection with the U-shaped heat pipe 32, and the low temperature surface 311 faces the inside of the condensing box 3. The design makes the refrigerating plate 31 directly contact with the U-shaped heat pipe 32, thereby reducing the heat propagation path and accelerating the heat dissipation efficiency. It should be noted that a sealing and heat insulating layer is required between the cooling plate 31 and the inner wall of the through hole, and this design is to increase the tightness of the condensation box 3. Secondly, in order to reduce the diffusion of heat from the cooling fin 31 to the side wall of the condensation box 3, the cooling rate in the condensation box 3 is affected.

As shown in fig. 4-5, in order to further accelerate the heat dissipation efficiency, a heat dissipation bin 4 is mounted on the side wall of the sealed box 2, the heat dissipation fins 33 are located in the heat dissipation bin 4, a plurality of heat dissipation fans 41 are mounted on the top of the heat dissipation bin 4, and an air outlet is formed in the bottom of the heat dissipation bin 4. The heat dissipation fan 41 sends outside air into the heat dissipation bin 4, the air undergoes heat exchange when passing through the heat dissipation fins 33, and then the air carries heat to be discharged to the outside from the air outlet. The number of the heat dissipation holes (not marked in the figure due to view angle) is a plurality of, and the shape of the heat dissipation holes can be customized according to the requirement. In order to prevent flying insects from entering the heat dissipation bin 4, the heat dissipation fan 41 and the air outlet are covered with sealing nets.

As shown in fig. 3, in order to increase the temperature decrease rate in the condensing tank 3, the heat exchange area of the cooling surface can be increased while increasing the heat dissipation efficiency of the cooling fin 31. For this purpose, a condensation net 34 is vertically arranged in the condensation box 3, and the condensation net 34 is in heat conduction connection with the low temperature surface 311.

In order to increase the dehumidifying capacity of the condensation tank 3, we need to increase the residence time of the air sample in the condensation tank 3. For this reason, a plurality of buffer plates 35 are disposed in the condensing box 3, and the plurality of buffer plates 35 are staggered from top to bottom. The both sides of the condensing box 3 are respectively provided with an air inlet hole and an air outlet hole, the air inlet hole and the air outlet hole are both connected with a sealing pipeline, the air inlet hole has the function of receiving an air sample from the dust detection piece 22, and the air outlet hole has the function of sending the dried air sample into the sealing pipeline. Wherein, there is the difference in height between fresh air inlet and the fresh air outlet, and a plurality of buffer plates 35 are located between fresh air inlet and the fresh air outlet. This design allows a considerably longer residence time of the air sample in the condensation tank 3, so that the moisture in the air sample can be removed sufficiently. The air sample is blocked by the buffer plate 35 and its flow rate is greatly reduced, which causes dust particles to accumulate in the condensation tank 3 due to its own weight.

As shown in fig. 3, in order to facilitate the drainage of water in the condensation box 3, a conical water collection bin 36 is arranged at the bottom of the condensation box 3, a water collection pipe 361 is installed at the bottom of the water collection bin 36, and one end, far away from the water collection bin 36, of the water collection pipe 361 is connected with a temporary storage box 37. The temporary storage box 37 can be connected with the outside through a pipeline, so as to facilitate the water discharge.

Since the filtering effect of the condensing box 3 on dust particles is limited, in order to avoid dust from affecting subsequent detection, a dust filter 24 is arranged between the air detection box 23 and the condensing box 3, filter cotton is filled in the dust filter 24, and the condensing box 3, the dust filter 24 and the air detection box 23 are connected through sealing pipelines in sequence. In order to ensure that the dust filter 24 only filters dust, a filter filled with filter cotton is selected in this embodiment, wherein the filter cotton is preferably synthetic fiber filter cotton or glass fiber filter cotton.

Since the low-temperature gas also affects the detection accuracy of the detection member, a heating chamber 25 is provided between the dust filter 24 and the air detection box 23, and a heating wire 251 is installed in the heating chamber 25. The heating wires 251 are spirally arranged in the heating bin 25, so that the length of the heating wires 251 in the heating bin 25 is increased, the contact area between the heating wires 251 and air is increased, and the heating efficiency is accelerated. The dehumidified and dedusted air sample is heated by the heating wire 251 to make the temperature close to the room temperature, so as to improve the accuracy of the detection data of the subsequent detection piece.

As shown in fig. 3, in this embodiment, a gas detection array and a micro air pump 231 are disposed in the air detection box 23. The gas detection array is composed of a plurality of gas detection pieces arranged in an array mode. Wherein the gas detecting member has various choices, such as VOC detecting member, CO ₂ And a detecting piece. The type of the gas detection part is not fixed, and can be automatically increased or decreased according to the requirements. The micro air pump 231 is used for providing power for the transmission of the air sample.

As shown in fig. 1, for easy installation and maintenance, the side wall of the sealed box 2 is provided with a sealing door 26, and the sealing door 26 is sequentially provided with an information display 261, a door lock 262 and a handle 263 from top to bottom. The information display screen 261 is connected with each detection piece in an electrified mode, and the information display screen 261 can collect and display various data, so that a manager can conveniently check the data. The purpose of door lock 262 and handle 263 is to avoid sealing door 26 from being opened at will.

In summary, the scheme has the following beneficial effects: firstly, the air sample passes through the humidity detecting member 21 and the dust detecting member 22, and then reaches the condensing box 3. The design ensures that the environment monitoring instrument is used for removing water and dust from an air sample after acquiring the humidity and dust particle data, and the influence of the moisture and the dust particles on the subsequent gas detection is avoided. Meanwhile, after the air sample is subjected to water removal and dust removal, the probability of agglomerating dust particles in a pipeline is greatly reduced, the problem of pipeline blockage is avoided, and therefore the accuracy of air monitoring data is guaranteed. Secondly, the refrigerating sheet 31 replaces the traditional liquid cooling mode, and the phenomenon of liquid leakage in the traditional liquid cooling mode is avoided. And thirdly, the U-shaped heat pipe 32 and the radiating fins 33 are introduced, so that the radiating efficiency of the refrigerating sheet 31 is improved, the temperature reduction speed in the condensing box 3 is further improved, and the normal operation of dehumidification is ensured.
