[0002] In chemical experiments, the reaction process of chemical reagents easily generates organic waste gases, which need to be treated to prevent direct emissions that could affect the health of laboratory personnel. Existing laboratory organic waste gas treatment devices often lack dust-proof structures, making it easy for dust to interfere with the effectiveness of ultraviolet lamps in treating the organic waste gases.

[0003] In existing technologies, laboratory organic waste gas entering the enclosure is treated by dust removal through a dustproof plate, and then the waste gas is irradiated by an ultraviolet lamp to complete the treatment of the organic waste gas. In this method, the waste gas directly passes through the irradiation range of the ultraviolet lamp, which cannot change the flow path of the waste gas, reduces the irradiation treatment time of the ultraviolet lamp on the waste gas, and easily affects the treatment effect of the waste gas. Utility Model Content

[0004] The purpose of this invention is to propose a laboratory organic waste gas treatment device to solve the problem that in traditional technologies, waste gas is directly irradiated by ultraviolet lamps, which cannot change the flow path of the waste gas, reduces the irradiation time of the ultraviolet lamps, and easily affects the treatment effect of the waste gas.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The outer casing has an air inlet pipe connected to one end and an air outlet pipe connected to the other end.

[0008] The processing mechanism includes an exhaust fan installed on the side of the outer casing, with its input end connected to the end of the exhaust pipe away from the outer casing. Multiple ultraviolet lamps are installed on the top of the inner casing, and multiple mounting slots are provided. Baffles are slidably connected to the mounting slots, and the multiple baffles divide the inner casing into multiple bend channels. The input end of each bend channel is connected to the air inlet pipe, and the output end is connected to the air outlet pipe. The ultraviolet lamps output in the direction of the bend channels. A first activated carbon layer is fixedly connected to the side of each baffle.

[0009] Preferably, a filter screen is fixedly connected inside the air inlet pipe, and a second activated carbon layer is fixedly connected inside the air outlet pipe.

[0010] Preferably, all of the ultraviolet lamps are arranged at an angle, and their output range covers the interior of the multi-bend flow channel.

[0011] Preferably, the baffle includes a sealing block, which is slidably sealed to the mounting groove. A rotating rod is rotatably connected to the sealing block, and a baffle is rotatably connected to its bottom. The bottom end of the rotating rod passes through the sealing block and is slidably coaxially connected to the baffle. The top of the baffle is slidably sealed to the top of the inner shell, and the bottom is slidably sealed to the bottom of the inner shell. The baffle forms part of the sidewall of the multi-bend flow channel, and the first activated carbon layer is fixedly connected to the surface of the baffle.

[0012] Preferably, a rotating groove is formed through the sealing block, and the rotating rod is in a sealing rotational engagement with the rotating groove.

[0013] Preferably, a snap-fit ​​block is fixedly connected to the rotating rod, and multiple snap-fit ​​grooves are opened on the top of the sealing block, with the snap-fit ​​block engaging with one of the snap-fit ​​grooves.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, by setting up a processing mechanism, the inside of the outer shell is divided into multiple curved channels by a baffle plate, which prolongs the flow path of the exhaust gas and increases the residence time of the exhaust gas in the outer shell, thereby improving the irradiation treatment effect of the ultraviolet lamp on the exhaust gas; and a first activated carbon layer is set on the baffle plate, which forms an adsorption effect on the exhaust gas when the exhaust gas flows through, further improving the treatment effect of the exhaust gas.

[0016] 2. In this utility model, by setting a detachable baffle, it is convenient to replace the baffle, effectively preventing the first activated carbon layer on the baffle from becoming saturated and ensuring the adsorption treatment effect of the first activated carbon layer on the baffle on the waste gas; at the same time, the baffle block in the baffle can rotate, which can easily change the shape of the multi-bend flow channel to change the flow path of the waste gas and improve the adaptability to the treatment of waste gas of different concentrations; and the baffle can be rotated and flipped, thereby improving the utilization effect of the first activated carbon layer on the back of the baffle; and after the baffle block rotates, it is locked into the outer shell, which improves the limiting effect of the baffle block and prevents it from easily falling out.

Detailed Implementation

[0023] 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.

[0024] Reference Figures 1-5 Laboratory organic waste gas treatment device, including:

[0025] The outer casing 1 has an air inlet pipe 2 connected to one end and an air outlet pipe 3 connected to the other end.

[0026] A filter screen 16 is fixedly connected inside the air inlet pipe 2, and a second activated carbon layer 17 is fixedly connected inside the air outlet pipe 3.

[0027] Laboratory organic waste gas enters the interior of the outer shell 1 through the air inlet pipe 2. The filter screen 16 performs preliminary filtration of the incoming organic waste gas, intercepting dust in the waste gas and preventing dust from affecting the subsequent treatment process.

[0028] The treated waste gas is discharged through the exhaust pipe 3, and the second activated carbon layer 17 adsorbs the waste gas again, improving the treatment effect of the waste gas.

[0029] The processing mechanism includes an exhaust fan 4, which is installed on the side of the outer casing 1 and its input end is connected to the end of the exhaust pipe 3 away from the outer casing 1. Multiple ultraviolet lamps 5 are installed on the top inside the outer casing 1 and multiple mounting slots 6 are provided. A baffle plate 7 is sealed and slidably connected in the mounting slot 6. The multiple baffle plates 7 divide the inside of the outer casing 1 into a multi-bend flow channel 9. The input end of the multi-bend flow channel 9 is connected to the air inlet pipe 2 and the output end is connected to the air outlet pipe 3. The output direction of the ultraviolet lamps 5 points into the inside of the multi-bend flow channel 9. A first activated carbon layer 8 is fixedly connected to the side of the baffle plate 7.

[0030] Multiple UV lamps 5 are all tilted, and their output range covers the interior of the multi-bend flow channel 9.

[0031] At the top of a section of the multi-bend flow channel 9, multiple ultraviolet lamps 5 are tilted and symmetrically distributed, so that the output range of the ultraviolet lamps 5 completely covers this section of the flow channel, achieving comprehensive irradiation treatment of the exhaust gas passing through this section of the flow channel.

[0032] The baffle 7 includes a sealing block 10, which is in a sealing sliding fit with the mounting groove 6. A rotating rod 12 is rotatably connected to the sealing block 10, and a baffle block 13 is rotatably connected to the bottom of the sealing block 10. The bottom end of the rotating rod 12 passes through the sealing block 10 and is slidably connected to the baffle block 13 on the same axis. The top of the baffle block 13 is in a sealing sliding fit with the top of the inner shell 1, and the bottom is in a sealing sliding fit with the bottom of the inner shell 1. The baffle block 13 forms part of the sidewall of the multi-bend flow channel 9, and the first activated carbon layer 8 is fixedly connected to the surface of the baffle block 13.

[0033] When installing the baffle 7, insert the baffle block 13 and the sealing block 10 into the mounting groove 6, and then control the rotating rod 12 to rotate, so that the baffle 7 extending into the outer shell 1 can rotate. This makes it easy to adjust the angle of the baffle 7, change the shape of the multi-bend flow channel 9, change the flow path of the exhaust gas, improve the adaptability to the treatment of exhaust gas of different concentrations, and make the baffle 7 rotate and flip over, so that the first activated carbon layer 8 on the back of the baffle 7 faces the exhaust gas flow, improve the utilization effect of the first activated carbon layer 8 on the baffle 7, and the first activated carbon layer 8 forms an adsorption treatment effect on the exhaust gas.

[0034] After the baffle block 13 rotates, it is locked into the outer casing 1, which improves the limiting effect of the baffle block 13 and prevents it from easily coming out.

[0035] When it is necessary to disassemble the baffle plate 7, rotate the baffle block 13 to reset it, and then pull out the baffle block 13 and the sealing block 10 to replace the baffle plate 7. This effectively avoids the first activated carbon layer 8 becoming saturated and affecting the treatment effect on the exhaust gas.

[0036] A rotating groove 11 is provided through the sealing block 10, and the rotating rod 12 is sealed and rotated in the rotating groove 11 to prevent air leakage between the sealing block 10 and the rotating rod 12.

[0037] A snap-fit ​​block 14 is fixedly connected to the rotating rod 12, and multiple snap-fit ​​grooves 15 are opened on the top of the sealing block 10. The snap-fit ​​block 14 is engaged with one snap-fit ​​groove 15.

[0038] After rotating the angle of the baffle block 13, move the rotating rod 12 downward to allow the snap-fit ​​block 14 to snap into a snap-fit ​​groove 15, thus limiting the angle of the baffle block 13 and preventing it from deflecting under the flow of air, thereby improving the stability of the multi-bend flow channel 9.

[0039] 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.
