Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, and in particular to a post-filter for boron diffuser exhaust. Background Technology

[0002] In the process of treating boron oxide emissions, the common method is to first cool the exhaust gas before passing it into a water filtration system. The exhaust gas is then hydrolyzed to retain boron oxide in the collection bottle of the water filtration system. Finally, a vacuum pump is used to discharge the treated exhaust gas to the outside.

[0003] While the above methods can effectively remove boron oxide from exhaust gases, they still have certain drawbacks:

[0004] (1) Boron oxide in the exhaust gas may not be completely dissolved in water and may directly enter the vacuum pump through the pipeline, resulting in excessive pump speed and vacuum alarm.

[0005] (2) The water filtration system may bring excessive water into the vacuum pump during the gas flow extraction process, which may damage the vacuum pump.

[0006] Based on this, the present invention provides a post-filter for boron diffuser tail discharge to solve the problems mentioned above. Utility Model Content

[0023] Figure 2 This is a schematic diagram of the installation of the post-filter of the present invention for boron diffuser tail exhaust in a boron diffuser tail exhaust treatment system. Detailed Implementation

[0024] The post-filter for boron diffuser tailpipes of this invention will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of the invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the invention.

[0025] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0026] like Figure 1As shown in the figure, this utility model embodiment proposes a post-filter for boron diffuser tail exhaust, including a housing 1 and a filter cotton 2; an air inlet pipe 3 and an air outlet pipe 4 are respectively provided at a certain height at both ends of the outer side of the housing 1; the filter cotton 2 is installed inside the housing 1, and the side wall of the filter cotton 2 is tightly fitted to the inner side wall of the housing 1.

[0027] In use, connect the inlet pipe 3 to the outlet of the water filter system 03 of the boron diffuser exhaust system, and connect the outlet pipe 4 to the inlet of the vacuum pump 04, such as... Figure 2 As shown.

[0028] The exhaust gas generated by the diffusion furnace 01 enters the water filtration system 03 for preliminary filtration after passing through the cooling bottle 02. Then, it enters the housing 1 through the inlet pipe 3. The filter cotton 2 can further separate the residual particles or powder in the gas, and at the same time, it can absorb and separate the moisture in the gas. Since the inlet pipe 3 and the outlet pipe 4 are respectively located at a certain height at both ends of the housing 1, the separation of the filter cotton 2 can be stored inside the housing 1. Therefore, the gas can effectively remove particles and moisture after passing through the filter cotton 2, effectively avoiding the occurrence of vacuum pump dust accumulation and blockage due to occasional insufficient filtration. At the same time, it effectively reduces the risk of the exhaust gas carrying excessive water into the vacuum pump, thereby extending the service life of the vacuum pump.

[0029] In the above embodiments, the filter cotton 2 is made of polyurethane material.

[0030] Polyurethane filter cotton has good resistance to many chemicals and is not easily corroded by acids, alkalis, salts, and other chemicals. At the same time, polyurethane filter cotton has a porous structure, and these pores can adsorb water molecules in the air. When air containing moisture passes through the filter cotton, the water molecules are physically adsorbed on the surface of the pores.

[0031] Preferably, the thickness of filter cotton 2 is 5mm-50mm to ensure that filter cotton 2 has a good effect on filtering particles and dust as well as water absorption.

[0032] Furthermore, the filter cotton 2 is located inside the housing 1 near the end of the exhaust pipe 4, which effectively prevents the exhaust gas after being dehydrated by the filter cotton 2 from coming into contact with the moisture stored in the housing 1 again, thereby improving the dehydration effect on the exhaust gas.

[0033] In one specific embodiment, the housing 1 includes a first open container 11 and a second open container 12, which are respectively provided with the air inlet pipe 3 and the air outlet pipe 4; the open end of the first open container 11 and the open end of the second open container 12 are detachably connected to form the housing 1.

[0034] Specifically, the opening end of the first open container 11 and the opening end of the second open container 12 are detachably connected by a quick-release clamp 5.

[0035] Quick-release clamps are clamps that can be installed and removed quickly. Compared to traditional clamps, quick-release clamps do not require complicated tools or cumbersome operating procedures, and can be installed and removed in a short time, significantly improving work efficiency. The specific structure and installation method of quick-release clamp 5 are existing technology and will not be described in detail here.

[0036] In summary, the housing 1 adopts a split design, and with the quick-release clamp 5, it is convenient to maintain and replace the filter cotton 2 inside the housing 1 and to drain the water stored inside the housing 1.

[0037] In the above specific embodiments, in order to clearly understand when to maintain and replace the filter cotton 2 and when to drain the moisture inside the housing 1, the housing 1 is made of transparent material, and the material color of the filter cotton 2 is dark, such as black. This is because the expanded particles or powder are mostly white. By setting the filter cotton 2 to a dark color, it is easier to understand the usage of the filter cotton 2.

[0038] In the specific embodiments described above, the first open container 11 and the second open container 12 have the same shape and size to facilitate the manufacturing of the shell 1.

[0039] Furthermore, at least one of the first open container 11 and the second open container 12 has a sealing gasket (not shown in the figure) on its open end face to ensure the airtightness of the shell 1 and prevent air and water leakage.

[0040] In summary, the post-filter for the boron diffuser exhaust provided by this invention can further separate particles or powder from the exhaust gas filtered by the water filtration system, effectively preventing dust accumulation and blockage of the vacuum pump due to occasional insufficient filtration. Simultaneously, the post-filter for the boron diffuser exhaust provided by this invention can also separate and collect moisture from the exhaust gas filtered by the water filtration system, effectively reducing the risk of excessive water entering the vacuum pump due to the exhaust gas carrying it, and extending the service life of the vacuum pump.

[0041] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
