Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas monitoring technology, and in particular to an online monitoring device for industrial waste gas treatment. Background Technology
[0002] Industrial waste gas refers to the general term for various gaseous pollutants emitted into the atmosphere during industrial production processes. These gaseous pollutants usually originate from various combustion processes, chemical reactions, and material processing in industrial production activities.
[0003] Industrial waste gas has a serious negative impact on the environment and ecosystems. Monitoring and treatment help reduce the emission of these pollutants. For example, Chinese Patent Publication No. CN219084871 U discloses a waste gas monitoring device, including a waste gas monitoring box and a waste gas collection pipe. A sleeve block is fixedly installed on the top of the waste gas monitoring box, and an annular groove is formed on the sleeve block. A dustproof mesh cover is fitted over the waste gas collection pipe, and the bottom of the dustproof mesh cover is inserted into the annular groove. A first strong magnetic ring is embedded in the annular groove. A second strong magnetic ring is embedded in the bottom of the dustproof mesh cover, and the second strong magnetic ring is attracted to the first strong magnetic ring. The waste gas monitoring device provided by this utility model has the advantage of blocking debris, preventing debris from entering the monitoring instrument and affecting the normal operation of the equipment.
[0004] In practice, the dust cover is fixed to the top of the monitoring box by the first and second strong magnets. However, considering that the magnets may weaken after long-term use or repeated opening and closing of the dust cover, and that it is inconvenient to replace the strong magnets, which would affect the efficiency of subsequent gas monitoring, and that the rain cap and dust cover cannot be disassembled, it is inconvenient to clean after long-term use. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the weakening of magnetism after prolonged use making replacement inconvenient, and the inability to detach the rain cap and dust cover. Therefore, this invention proposes an online monitoring device for industrial waste gas treatment.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design an online monitoring device for industrial waste gas treatment, including a waste gas monitoring box, a collection tube connected to the top of the waste gas monitoring box, and a first filter cover and a second filter cover provided at the top of the collection tube. The first filter cover and the second filter cover are fitted inside and outside each other to block dust.
[0008] The first filter cover is detachably connected to the collection tube, the second filter cover is fixed to the top of the collection tube by a quick-release assembly, and a rain cover is provided on the top of the second filter cover.
[0009] Furthermore, the collection tube is connected to the monitoring device inside the exhaust gas monitoring box, and an installation part is fixedly connected to the top periphery of the collection tube. An annular part is provided at the top midpoint of the installation part, and the bottom of the first filter cover is threadedly connected to the annular part.
[0010] Furthermore, the bottom through hole of the second filter cover matches the annular part, and a fixing part is fixedly connected to the bottom periphery of the second filter cover. The bottom circumferential array of the fixing part has several deformation grooves, which are L-shaped and whose bottoms are all connected to the fixing part.
[0011] Furthermore, a connecting rod is provided around the annular portion, and an upwardly extending abutment portion is provided on the side of the deformation groove near the opening. The connecting rod is correspondingly provided with the deformation groove, and the connecting rod slides against the abutment portion and is disposed within the deformation groove.
[0012] Furthermore, the top of the rain shelter is truncated cone-shaped, and a fixing rod is fixedly connected to the midpoint of its bottom. A baffle is fixedly connected to the free end of the fixing rod, and the free end of the baffle passes through the top of the second filter cover, with the baffle abutting against the second filter cover.
[0013] Furthermore, at least one positioning glass bead is embedded on the side of the free end of the fixed rod, and the positioning glass bead abuts against the top of the inner wall of the second filter cover.
[0014] The present invention provides an online monitoring device for industrial waste gas treatment, which has the following advantages: The present invention has a first dust cover and a second dust cover on the top of the collection tube. The first dust cover and the second dust cover are nested together. The advantage is that they can filter impurities in the waste gas and prevent impurities from entering the collection tube, causing blockage or affecting the accuracy of monitoring. The second dust cover is used to filter and block large particulate impurities. Therefore, the second dust cover can be quickly detached from the first dust cover by a quick-release method, which is convenient for cleaning impurities and avoids affecting the monitoring efficiency. In addition, the rain cover can also be quickly removed and cleaned to prevent the accumulation of impurities on its inner wall and affect its use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-4 An online monitoring device for industrial waste gas treatment includes a waste gas monitoring box 1. A collection pipe 2 is connected to the top of the waste gas monitoring box 1. A first filter cover 3 and a second filter cover 4 are provided at the top of the collection pipe 2. The first filter cover 3 and the second filter cover 4 are fitted inside and outside each other to block dust.
[0022] The first filter cover 3 is detachably connected to the collection tube 2, the second filter cover 4 is fixed to the top of the collection tube 2 by a quick-release assembly 5, and a rain cover 6 is also provided on the top of the second filter cover 4.
[0023] Furthermore, the collection pipe 2 is connected to the monitoring device inside the exhaust gas monitoring box 1, and an installation part 21 is fixedly connected to the top periphery of the collection pipe 2. An annular part 22 is provided at the top midpoint of the installation part 21, and the bottom of the first filter cover 3 is threadedly connected to the annular part 22.
[0024] Furthermore, the bottom through hole of the second filter cover 4 matches the annular part 22, and a fixing part 41 is fixedly connected to the bottom periphery of the second filter cover 4. The bottom circumferential array of the fixing part 41 has a plurality of deformation grooves 42, which are L-shaped and whose bottoms are all connected to the fixing part 41.
[0025] It is worth mentioning that the diameter of the filter holes on the outer wall of the first filter cover 3 is smaller than that of the second filter cover 4. The advantage is that the second filter cover 4 is used to filter large particles of impurities. Firstly, it reduces the filtration burden on the first filter cover 3 and works better with the first filter cover 3 to perform cavity filtration. Secondly, it reduces the number of times the first filter cover 3 needs to be disassembled and cleaned. Therefore, the second filter cover 4 can be quickly disassembled and cleaned through the quick-release structure.
[0026] A sealing gasket is provided between the bottom of the second filter cover 4 and the top of the mounting part 21 to prevent gaps from forming between the second filter cover 4 and the mounting part 21, thus preventing exhaust gas from directly entering the second filter cover 4 through the gap.
[0027] More specifically, the annular portion 22 is provided with a connecting rod 51 on its periphery, and the deformation groove 42 has an upwardly extending abutment portion 43 on the side near the opening. The connecting rod 51 is correspondingly provided with the deformation groove 42, and the connecting rod 51 slides against the abutment portion 43 and is disposed within the deformation groove 42.
[0028] It is worth mentioning that the fixing part 41 is preferably made of a material with deformation capability, such as plastic or rubber. The connecting rod 51 is disposed in the fixing part 41 through the opening of the deformation groove 42. When the second filter cover 4 is rotated, the connecting rod 51 abuts against the abutting part 43. The abutting part 43 deforms due to the abutment, and then the connecting rod 51 is disposed in the deformation groove 42 to fix the second filter cover 4.
[0029] In general, the top of the rain shelter 6 is truncated cone-shaped, and a fixing rod 61 is fixedly connected to the midpoint of its bottom. A baffle 62 is fixedly connected to the free end of the fixing rod 61, and the free end of the baffle 62 passes through the top of the second filter cover 4. The baffle 62 abuts against the second filter cover 4.
[0030] Finally, at least one positioning glass bead 63 is embedded on the side of the free end of the fixing rod 61, and the positioning glass bead 63 abuts against the top of the inner wall of the second filter cover 4.
[0031] Specifically, by setting up a rain cover 6, a pair of filter covers can be shielded from rainwater to prevent rainwater erosion. Pressing the positioning glass bead 63 causes its positioning bead end to retract inward, and then the fixing rod 61 is set inside the second filter cover 4. The positioning glass bead 63, together with the baffle plate 62, fixes the rain cover 6.
[0032] Operating procedure: During operation, the first filter cover 3 is fixedly connected to the collection tube 2 via a threaded connection with the annular portion 22, and then the second filter cover 4 is fitted around the first filter cover 3.
[0033] The connecting rod 51 is disposed in the fixing part 41 through the opening of the deformation groove 42. The second filter cover 4 is rotated so that the connecting rod 51 abuts against the abutting part 43. The abutting part 43 deforms due to the abutment, and then the connecting rod 51 is disposed in the deformation groove 42 to fix the second filter cover 4.
[0034] The rain cover 6 is fixed to the top of the second filter cover 4 by positioning glass beads 63 and baffle 62. After the second filter cover 4 works with the first filter cover 3 to filter impurities in the exhaust gas, the monitoring device collects the exhaust gas through the collection tube 2 and monitors the exhaust gas.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
