Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tubeless gas purification microwave digestion workbench, specifically a movable tubeless gas purification microwave digestion workbench. Background Technology
[0002] When analyzing and determining the content of various metals in the laboratory, sample pretreatment is necessary. Microwave digestion is increasingly becoming the preferred method for laboratory workers due to its advantages of small sample volume and short digestion time. However, microwave digestion generates hot acid fumes, which can harm and pollute laboratory personnel and the environment if directly discharged. Currently, the exhaust pipe of the microwave digester is usually placed in a fume hood. While this solves the problem of acid fumes discharge, it obstructs other experiments and affects aesthetics. If the laboratory is limited by factors such as ceiling height and cannot install a fume hood, exhaust pipes, and fan, it can also affect the normal operation of microwave digestion pretreatment. Therefore, we propose a portable, ductless, air-purifying microwave digestion workbench. Utility Model Content

It solves the problem that currently, the exhaust pipe of the microwave digester is usually placed in the fume hood. Although this can solve the problem of acid mist discharge from the digester, it will occupy and interfere with the normal operation of other experiments in the fume hood, and also affect the aesthetics. If the laboratory is limited by environmental conditions such as floor height and cannot install the fume hood exhaust pipe and fan body, it will also affect the normal operation of microwave digestion pretreatment.

[0019] Example:
[0020] Please see Figure 1-2As shown, this utility model provides a portable, tubeless, air-purifying microwave digestion workbench, including a workbench body 1. The workbench body 1 includes a tabletop 2 and a cabinet 3. The tabletop 2 is located on top of the cabinet 3. A decorative control panel 4 is provided on the upper part of the front of the cabinet 3. The decorative control panel 4 is equipped with a fan control system and a color display screen 5. A cabinet door 6 is provided on the front of the cabinet 3 and below the decorative control panel 4. A sealed drawer-type acid mist purification treatment box 7 is provided inside the cabinet 3. A back panel 8 is provided on the back of the cabinet 3. An indoor air inlet 9 and a treated acid mist exhaust outlet 10 are provided on the back panel 8. A microwave digester acid mist exhaust port 11 is provided in the middle. A sealed drawer-type acid mist purification treatment box 7 is equipped with an acid mist exhaust gas inlet 12. The microwave digester acid mist exhaust port 11 is sealed to the acid mist exhaust gas inlet 12. Side panels 13 are provided on both sides of the cabinet 3, and a bottom plate 14 is provided at the bottom of the cabinet 3. The sealed drawer-type acid mist purification treatment box 7 contains a first acid mist adsorption and purification layer 16, an acid mist inlet static pressure diffusion space layer 17, a second acid mist adsorption and purification layer 18, and a third adsorption and purification layer 19 for comprehensive inorganic and organic treatment of acid mist exhaust gas. The first acid mist adsorption and purification layer 16 is located at the acid mist inlet. The static pressure diffusion space layer 17 is located above the second acid mist adsorption and purification layer 18, which is located above the third adsorption and purification layer 19 for the integrated inorganic and organic treatment of acid mist exhaust gas. An exhaust space 20 is provided in the inner cavity of the sealed drawer-type acid mist purification treatment box 7, below the third adsorption and purification layer 19. The upper part of the first acid mist adsorption and purification layer 16 is connected to the indoor air. The static pressure diffusion space layer 17 is connected to the acid mist exhaust gas inlet 12 of the acid mist purification treatment box and the acid mist exhaust port 11 of the microwave digester. The lower left side of the acid mist purification treatment box 7 is equipped with a fan body 24. The fan body 24 is provided with an air inlet 21 and an exhaust port 22. The air inlet 21 is sealed to the exhaust space 20. The exhaust port 22 is connected to the treated acid mist exhaust port 10 through a connecting pipe. A TVOC sensor 23 is provided at the fan air inlet 21. The output end of the TVOC sensor 23 is electrically connected to the input end of the color display screen 5. The bottom plate 14 is provided with casters 15 around its bottom. The casters 15 are provided with latches. The tabletop 2 is made of acid-resistant material. The sealed drawer-type acid mist purification treatment box 7 is made of acid and alkali resistant material such as PVC box.
[0021] This technical solution uses the fan body 24 to generate suction, which draws the gas in the cavity through the air inlet 21. At this time, indoor air is drawn in from the indoor air inlet 9 on the upper part of the back panel 8. The acid mist generated by the microwave digester enters the acid mist inlet static pressure diffusion space layer 17 of the sealed drawer-type acid mist purification treatment box 7 through the microwave digester exhaust interface 11. After being evenly diffused in this space layer, it passes through the second acid mist adsorption purification layer 18 and the third adsorption purification layer 19 for deep purification treatment. The first acid mist adsorption purification layer 16 is a diffusion-proof protective layer. During this process, acidic substances, organic and inorganic impurities in the acid mist are gradually adsorbed, decomposed and transformed by each adsorption and purification layer, thus purifying the acid mist. The purified gas enters the exhaust space 20 and is then drawn out from the exhaust port 22 by the fan body 24 and discharged from the acid mist exhaust port 10 through the connecting pipe. During this process, the TVOC sensor 23 monitors the total organic carbon content in the exhaust gas in real time and transmits the data to the color display screen 5. The experimenter can judge whether the acid mist treatment effect meets the requirements based on the TVOC data displayed on the color display screen 5. If abnormal data or poor treatment effect is found, the speed of the fan body 24 can be adjusted in time, and the adsorption and purification layers can be checked for replacement or maintenance to ensure that the acid mist treatment process is continuously effective and stable.
[0022] The working principle of this utility model is as follows: the fan body 24 can generate suction, which causes the air inlet 21 to draw the gas in the cavity. At this time, the indoor air is drawn in from the indoor air inlet 9 on the upper part of the back panel 8. The acid mist generated by the microwave digester enters the acid mist inlet static pressure diffusion space layer 17 of the sealed drawer-type acid mist purification treatment box 7 through the acid mist exhaust interface 11 of the microwave digester. After being evenly diffused in this space layer, it passes through the second acid mist adsorption purification layer 18 and the third adsorption purification layer 19 for comprehensive inorganic and organic treatment of acid mist exhaust gas for deep purification. The first acid mist adsorption purification layer 16 is a diffusion protection layer. During this process, acidic substances, organic and inorganic impurities in the acid mist are gradually adsorbed, decomposed and transformed by each adsorption and purification layer, thus purifying the acid mist. The purified gas enters the exhaust space 20 and is then drawn out from the exhaust port 22 by the fan body 24. It is discharged from the treated acid mist exhaust port 10 through the connecting pipe. During this process, the TVOC sensor 23 monitors the total organic carbon content in the exhaust gas in real time and transmits the data to the color display screen 5. The experimenter can judge whether the acid mist treatment effect meets the requirements based on the TVOC data displayed on the color display screen 5. If abnormal data or poor treatment effect is found, the speed of the fan body 24 can be adjusted in time, and the adsorption and purification layers can be checked for replacement or maintenance to ensure that the acid mist treatment process is continuously effective and stable.
