Description

Technical Field

[0001] This utility model relates to the field of organic synthesis technology, and in particular to an organic synthesis waste gas treatment device. Background Technology

[0002] Organic synthesis refers to the chemical reaction that transforms simple and readily available inorganic or simple organic raw materials into more complex organic compounds through chemical methods. It is widely used in the production and processing of resins, rubber, fibers, dyes, pharmaceuticals, and other products. Organic synthesis reactions are mostly carried out inside synthesis tanks to better control the temperature, pressure, humidity, etc., inside the synthesis tank. During this process, waste gas is generated, which needs to be treated before it can be discharged.

[0003] A pharmaceutical organic synthesis apparatus with a waste gas purification system, disclosed in publication number CN211586524U, is described. During the reaction of pharmaceutical granules and catalysts, a large amount of waste gas is generated. This waste gas enters a purification chamber through an exhaust pipe, is filtered, and then discharged from the outlet, achieving the purpose of purifying the waste gas. Currently, waste gas purification systems generally directly introduce the waste gas into the purification chamber for treatment. However, some reactions produce waste gases at high temperatures. Directly introducing these gases into the purification chamber can easily negatively impact the adsorption capacity and lifespan of the activated carbon filter layer, affecting its lifespan and increasing operating costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the high temperature of waste gas generated by certain reactions can negatively impact the adsorption capacity and lifespan of the activated carbon filter layer when directly introduced into the purification chamber. This invention provides an organic synthesis waste gas treatment device that uses cooling water inside the first and second cooling cylinders to cool the waste gas flowing in the first and second cooling pipes, thereby achieving flue gas cooling.

[0005] To achieve the above objectives, an organic synthesis waste gas treatment device is provided, comprising a purification chamber, a cooling component, a water tank, and a refrigeration chamber. The cooling component is connected to the purification chamber via a gas guide pipe, and the water tank is connected to the cooling component via a water guide pipe. A circulation pump is installed on the water guide pipe, and the refrigeration chamber is connected to the water tank. The cooling component includes an installation box, inside which are installed a first cooling pipe and a second cooling pipe. A first cooling cylinder is fitted outside the first cooling pipe, and a second cooling cylinder is fitted outside the second cooling pipe.

[0006] As a further description of the above technical solution: an air inlet pipe is provided on one side of the first cooling pipe, an air outlet pipe is provided on one side of the second cooling pipe, the air outlet pipe is connected to the air guide pipe, and a first connecting pipe is provided between the first cooling pipe and the second cooling pipe.

[0007] As a further description of the above technical solution: a water inlet pipe is provided on one side of the first cooling cylinder, and a water outlet pipe is provided on one side of the second cooling cylinder. Both the water inlet pipe and the water outlet pipe are connected to the water tank through a water guide pipe. A second connecting pipe is provided between the first cooling cylinder and the second cooling cylinder.

[0008] As a further description of the above technical solution: the purification box is provided with a first purification frame, a second purification frame, a third purification frame and a filter frame arranged from top to bottom, an air inlet is provided below the filter frame and an air pump is provided above the purification box.

[0009] As a further description of the above technical solution: the first purification frame, the second purification frame, the third purification frame and the filter frame are all detachably connected to the purification box via a sliding plate, and the purification box has a sliding groove inside that is adapted to the sliding plate.

[0010] As a further description of the above technical solution: an inspection door is provided on the outside of the purification box, and a sealing gasket is provided between the inspection door and the purification box.

[0011] As a further description of the above technical solution: the first purification frame, the second purification frame and the third purification frame are respectively lined with alkaline activated carbon, acidic activated carbon and ordinary activated carbon, and the filter frame is provided with a filter screen.

[0012] As a further description of the above technical solution: handles are provided on the outer sides of the first purification frame, the second purification frame, and the third purification frame.

[0013] The above technical solution has the following advantages or beneficial effects:

[0014] This invention cools the generated waste gas by introducing it into a first cooling pipe through an inlet pipe, then into a second cooling pipe, and finally out through an outlet pipe into a purification chamber for purification and adsorption. Cooling water can be introduced into the first and second cooling cylinders through an inlet pipe. The cooling water inside the first and second cooling cylinders can cool the waste gas flowing in the first and second cooling pipes, thereby reducing the temperature of the flue gas and preventing the waste gas temperature from becoming too high when entering the purification chamber. This can extend the service life of the activated carbon filter layer in the purification chamber and save costs. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that the terms "vertical", "up", "down", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] like Figure 1-5 As shown, this utility model discloses an organic synthesis waste gas treatment device, comprising: a purification box 1; a cooling component 2 connected to the purification box 1 via a gas guide pipe 3; a water tank 4 connected to the cooling component 2 via a water guide pipe 5, on which a circulation pump 6 is installed; and a refrigeration box 7 connected to the water tank 4. The cooling component 2 includes an installation box 201, inside which a first cooling pipe 202 and a second cooling pipe 203 are installed. The first cooling pipe 202 is fitted with a first cooling cylinder 204, and the second cooling pipe 203 is fitted with a second cooling cylinder 205.

[0026] In this embodiment, the generated exhaust gas is cooled by entering the first cooling pipe 202 through the inlet pipe 206, then cooling it again through the second cooling pipe 203, and finally being discharged into the purification chamber 1 through the outlet pipe 211 for purification and adsorption. Cooling water can be introduced into the first cooling cylinder 204 and the second cooling cylinder 205 through the water inlet pipe 208. The cooling water inside the first cooling cylinder 204 and the second cooling cylinder 205 can cool the exhaust gas flowing in the first cooling pipe 202 and the second cooling pipe 203, thereby cooling the flue gas and preventing the exhaust gas temperature from being too high when entering the purification chamber 1. This can extend the service life of the activated carbon filter layer in the purification chamber 1 and save costs. At the same time, the cooled water will flow back into the water tank 4 through the water outlet pipe 209 for heat exchange and cooling, thereby achieving circulating cooling.

[0027] Specifically, an air inlet pipe 206 is provided on one side of the first cooling pipe 202, and an air outlet pipe 211 is provided on one side of the second cooling pipe 203. The air outlet pipe 211 is connected to the air guide pipe 3. A first connecting pipe 207 is provided between the first cooling pipe 202 and the second cooling pipe 203. A water inlet pipe 208 is provided on one side of the first cooling cylinder 204, and a water outlet pipe 209 is provided on one side of the second cooling cylinder 205. Both the water inlet pipe 208 and the water outlet pipe 209 are connected to the water tank 4 through the water guide pipe 5. A second connecting pipe 210 is provided between the first cooling cylinder 204 and the second cooling cylinder 205. Cooling water can be introduced into the first cooling cylinder 204 and the second cooling cylinder 205 through the water inlet pipe 208. The cooling water inside the first cooling cylinder 204 and the second cooling cylinder 205 can cool the exhaust gas flowing in the first cooling pipe 202 and the second cooling pipe 203, thereby cooling the flue gas. This prevents the cooling water from directly contacting the flue gas, thus preventing the generation of wastewater and reducing environmental pollution.

[0028] like Figure 1 and Figure 3 As shown, specifically, the purification chamber 1 is equipped with a first purification frame 101, a second purification frame 102, a third purification frame 103, and a filter frame 104 arranged sequentially from top to bottom. An air inlet 105 is provided below the filter frame 104, and an air pump 106 is provided above the purification chamber 1. By using the air pump 106 to extract and filter air, the exhaust gas entering from the bottom of the purification chamber 1 passes sequentially through the filter frame 104, the third purification frame 103, the second purification frame 102, and the first purification frame 101. Impurities can be filtered out through the filter frame 104, and the exhaust gas can be purified and adsorbed through the third purification frame 103, the second purification frame 102, and the first purification frame 101.

[0029] The first purification frame 101, the second purification frame 102, and the third purification frame 103 are respectively lined with alkaline activated carbon, acidic activated carbon, and ordinary activated carbon, and the filter frame 104 is equipped with a filter screen. Acidic activated carbon is strongly acidic and can adsorb oxidizing gases and vapors, such as SO2, NOx, and H2S. Alkaline activated carbon is an adsorbent obtained by treating the surface of activated carbon under alkaline conditions during the production process. Alkaline activated carbon is strongly alkaline and can adsorb acidic gases and vapors, such as HCl and HF. Ordinary activated carbon is a highly efficient adsorbent with a porous structure. The adsorption capacity of activated carbon mainly depends on its large number of pores.

[0030] like Figure 4 and Figure 5As shown, specifically, the first purification frame 101, the second purification frame 102, the third purification frame 103, and the filter frame 104 are all detachably connected to the purification box 1 via a sliding plate 107. The purification box 1 has a sliding groove 108 inside that matches the sliding plate 107. The sliding groove 108 inside the purification box 1 allows the first purification frame 101, the second purification frame 102, the third purification frame 103, and the filter frame 104 to be easily removed via the sliding plate 107. This facilitates the replacement of the activated carbon inside the first purification frame 101, the second purification frame 102, and the third purification frame 103, and the cleaning and maintenance of the filter screen of the filter frame 104, thus enhancing the practicality of the device.

[0031] The first purification frame 101, the second purification frame 102, and the third purification frame 103 are all provided with handles 111 on the outside, which facilitates the removal and placement of the first purification frame 101, the second purification frame 102, and the third purification frame 103.

[0032] like Figure 3 As shown, specifically, an inspection door 109 is provided on the outside of the purification box 1, and a sealing gasket 110 is provided between the inspection door 109 and the purification box 1; the inspection door 109 facilitates the inspection of the inside of the purification box 1, and the sealing gasket 110 enhances the sealing performance of the inspection door 109.

[0033] Working principle: The generated exhaust gas is cooled by entering the first cooling pipe 202 through the inlet pipe 206, and then cooling it through the second cooling pipe 203. Finally, it is discharged into the purification chamber 1 through the outlet pipe 211 for purification and adsorption. Cooling water can be introduced into the first cooling cylinder 204 and the second cooling cylinder 205 through the water inlet pipe 208. The cooling water inside the first cooling cylinder 204 and the second cooling cylinder 205 can cool the exhaust gas flowing in the first cooling pipe 202 and the second cooling pipe 203, thereby cooling the flue gas and preventing the exhaust gas temperature from being too high when entering the purification chamber 1. This can extend the service life of the activated carbon filter layer in the purification chamber 1 and save costs. At the same time, the cooled water will flow back into the water tank 4 through the water outlet pipe 209 for heat exchange and cooling, realizing cyclic cooling.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
