Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a biological treatment box for organic waste gas. Background Art

[0002] Organic waste gas treatment refers to the adsorption, filtration and purification of organic waste gas generated in the industrial production process. Malodorous substances mostly come from industries such as petroleum refining, pharmaceuticals, papermaking, leather making, fertilizers, food, casting, automobile manufacturing and textiles. Malodors can cause varying degrees of damage to the human respiratory system, circulatory system, digestive system, endocrine system and nervous system, so they need to be collected and treated.

[0003] According to China's authorized announcement number: CN213348305U, an integrated box-type biological treatment device for organic waste gas has the following beneficial effects: by setting a drying plate, the moisture in the waste gas can be fully absorbed, and the moisture can be prevented from entering the interior of the filter box and reducing the filtering effect of the activated carbon. The waste gas then passes through the filter box, and the interior of the filter box is provided with activated carbon, which can absorb harmful gases in the waste gas. There are three filter boxes, which can prevent some harmful gases from being directly discharged into the air after the activated carbon in one of the filter boxes reaches a saturated state. The filter plate can filter out particulate matter in the waste gas.

[0004] The inventor believes that after the exhaust gas is treated, the gas must first be sampled and tested. However, the above-mentioned technology lacks the function of gas sampling and testing, which makes it inconvenient to sample and test the gas after the exhaust gas is treated. If it is directly discharged, it will affect the health of personnel, and thus there are certain defects in use.

[0005] Therefore, it is necessary to provide a new biological treatment box for organic waste gas to solve the above technical problems. Utility Model Content

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The terms used in this document in the specification of the present utility model are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A biological treatment box for organic waste gas comprises a box body 1, the top of the box body 1 is connected with an air inlet pipe 2, the inner wall of the box body 1 is fixedly connected with a mounting groove 3, the inner wall of the mounting groove 3 is respectively slidably connected with a filter screen plate 4, a drying plate 5 and an activated carbon screen plate 6, a sealing door 8 is hinged on one side of the box body 1, the other side of the box body 1 is connected with an exhaust pipe, and an exhaust valve is arranged on the outer side of the exhaust pipe; a detection mechanism 7, the detection mechanism 7 comprises a vacuum pump 71 and a collection box 72 arranged on one side of the box body 1, a gas detector 73 is arranged on the top of the collection box 72, a detection hole 74 is opened on the top of the collection box 72, a sealing limit ring 75 is clamped on the inner wall of the detection hole 74, an exhaust pipe 76 is arranged at the exhaust end of the vacuum pump 71, one end of the exhaust pipe 76 is connected with one side of the box body 1, an electromagnetic valve 77 is arranged on the outer side of the exhaust pipe 76, and an air supply pipe 78 is arranged at the exhaust end of the vacuum pump 71, and one end of the air supply pipe 78 is connected with one side of the collection box 72.

[0022] In the specific implementation process, Figure 1-Figure 5 As shown, a fan 9 is arranged on the top of the box body 1, and limiting holes 10 are provided on the inner walls of the filter screen plate 4, the drying plate 5 and the activated carbon screen plate 6.

[0023] The inner wall of the mounting groove 3 is slidably connected with a limiting rod 11 used in conjunction with the limiting hole 10 , the top of the limiting rod 11 is fixedly connected with a connecting block 12 , a spring 13 is arranged on the outer side of the limiting rod 11 , and a pull ring is arranged on the top of the connecting block 12 .

[0024] One end of the spring 13 is fixedly connected to the top of the mounting groove 3 , and the other end of the spring 13 is fixedly connected to the bottom of the connecting block 12 .

[0025] It should be noted that: first check that the solenoid valve 77 and the exhaust valve are in the closed state, and then introduce the gas into the box body 1 from the air inlet pipe 2. After the gas enters the box body 1, the particulate impurities in the gas can be filtered through the filter screen 4, the moisture in the gas can be absorbed through the drying plate 5, and the toxic substances in the gas (such as formaldehyde, iodine and chlorine, etc.) can be adsorbed through the activated carbon screen 6. At this time, the probe of the gas detector 73 is inserted into the sealing limit ring 75, and then the probe is moved to insert the sealing limit ring 75 into the detection hole 74. At this time, the probe is located in the collection box 72, and then the solenoid valve 77 and the vacuum pump 71 are started. The vacuum pump 71 sucks air into the exhaust pipe 76 to form a negative pressure inside it, so that the gas inside the box body 1 is extracted and introduced into the collection box 72 through the air supply pipe 78. When the gas is introduced into the collection box 72 and contacts with the probe of the gas detector 73, the vacuum pump 71 and the solenoid valve 77 are immediately turned off. The magnetic valve 77 can be used to determine whether the gas meets the standard through the value displayed on the display screen of the gas detector 73, so as to avoid direct discharge that affects the health of personnel. By opening the fan 9 and the exhaust valve, the gas that meets the standard can be discharged from the exhaust pipe. The fan 9 can make the gas in the box 1 flow, thereby accelerating the discharge speed. When it is necessary to replace the filter screen plate 4, the drying plate 5 and the activated carbon screen plate 6, first open the sealing door 8, and then pull the pull ring to make the connecting block 12 drive the limit rod 11 to move and separate it from the limit hole 10, so that the spring 13 is stretched, so that the filter screen plate 4 can be easily disassembled and replaced. The operation is convenient and quick. Then the new filter screen plate 4 is installed in the installation groove 3. At this time, the pull ring is released, and the limit rod 11 can be automatically reset and inserted into the limit hole 10 through the rebound force of the spring 13, so that the filter screen plate 4 can be fixed. Repeat the above operation to disassemble, replace and install the drying plate 5 and the activated carbon screen plate 6 in turn.

[0026] The working principle of a biological treatment box for organic waste gas provided by the utility model is as follows:

[0027] When in use, insert the probe of the gas detector 73 into the sealing limit ring 75, and move the probe to insert the sealing limit ring 75 into the detection hole 74, then start the solenoid valve 77 and the vacuum pump 71, the vacuum pump 71 extracts the gas inside the box 1 through the exhaust pipe 76, and introduces it into the collection box 72 through the gas pipe 78. When the gas contacts the probe of the gas detector 73, the value displayed on the display screen of the gas detector 73 can be used to know whether the gas meets the standard, thereby completing the gas sampling and detection work to avoid direct emissions that affect people's health.
