Description

Technical Field

[0001] This invention belongs to the field of activated carbon adsorption technology, and particularly relates to an activated carbon adsorption device for the purification of tert-butylhexane peroxide. Background Technology

[0002] tert-Butylhexane peroxide (TBHP) is a key oxidant in organic synthesis, and its purity directly affects the selectivity and safety of the reaction. In industrial production, crude TBHP often contains low-boiling-point byproducts such as tert-butanol and ketones, as well as unreacted raw materials. Traditional purification processes mainly rely on activated carbon adsorption. However, activated carbon has limited physical adsorption capacity for low-boiling-point organic compounds (such as tert-butanol with a boiling point below 100°C) and cannot effectively handle chemically active impurities (such as polymerizable olefins). Therefore, catalysis is needed to separate these impurities before adsorption by activated carbon.

[0003] The problem with the existing technology is that the existing heating catalysis channel is a straight channel. The gas flow rate is too fast and the contact heat exchange distance is too short, which affects the catalytic efficiency. Moreover, the size of the device is fixed, and it is difficult to adjust the length of the straight channel, which affects the efficiency of use. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art by proposing an activated carbon adsorption device for the purification of tert-butylhexane peroxide.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is: an activated carbon adsorption device for purifying tert-butylhexane peroxide, comprising a shell, wherein a filter frame for filtering the gas generated during purification is installed on the inner wall of the shell; and a guide frame installed below the filter frame for heating and catalyzing the gas.

[0006] The guide frame includes a conical block, and multiple spiral heat-conducting plates are provided on the outer side of the conical block in a ring array. The bottom end of the spiral heat-conducting plate corresponds to the air inlet of the shell, and a spiral channel is formed between adjacent spiral heat-conducting plates to extend the gas transmission distance.

[0007] Preferably, the housing includes an upper shell and a lower shell connected to the upper shell, and the bottom end of the lower shell has a tapered groove.

[0008] Preferably, the inner wall of the conical block has a cavity, and a heating column is installed inside the cavity. A heat-conducting block is connected to the side wall of the heating column. The end of the heat-conducting block away from the heating column is fixedly connected to one end of the spiral heat-conducting plate. The heat generated by the heating column is conducted to the spiral heat-conducting plate through the heat-conducting block for heat exchange catalysis of the conducted gas.

[0009] Preferably, the filter frame includes an inner frame, the outer side of which is wrapped with a filter screen, and the space between the inner side of the filter screen and the inner frame is filled with activated carbon.

[0010] Preferably, an exhaust port is provided at the top of the inner frame, and an air-gathering frame is installed at the top of the inner wall of the exhaust port.

[0011] Preferably, the top end of the conical block is fixedly connected to the bottom end of the inner frame.

[0012] Preferably, a conical space is formed between the outer wall of the conical block and the inner wall of the conical groove for conducting the incoming gas.

[0013] Preferably, the transmission space of the conical space increases from bottom to top, thereby reducing the gas flow rate and extending the contact time with the spiral heat-conducting plate.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0015] 1. The activated carbon adsorption device for purifying tert-butylhexane peroxide transmits gas through a transmission channel between two adjacent spiral heat-conducting plates. In the spiral channel formed by the two adjacent spiral heat-conducting plates, the contact distance between the gas and the spiral heat-conducting plates is extended, thereby improving the heating and catalytic efficiency.

[0016] 2. The activated carbon adsorption device for purifying tert-butylhexane peroxide has a conical space formed between the outer wall of the conical block and the inner wall of the conical groove. The diameter of the conical space increases from bottom to top, making the inlet channel smaller than the outlet channel. This reduces the atmospheric pressure and thus lowers the gas flow rate and prolongs the contact time with the spiral heat-conducting plate. Attached Figure Description

[0026] Reference Figures 1-4 An activated carbon adsorption device for purifying tert-butylhexane peroxide includes a shell 1, a filter frame 7 for filtering the purified gas installed on the inner wall of the shell 1, and a guide frame installed below the filter frame 7 for heating and catalyzing the gas. The shell 1 includes an upper shell 101 and a lower shell 102 connected to the upper shell 101.

[0027] The guide frame includes a conical block 202, and multiple spiral heat-conducting plates 203 are provided on the outer side of the conical block 202 in a ring array. The bottom end corresponds to the air inlet 3 of the housing 1. A spiral channel is formed between adjacent spiral heat-conducting plates 203 to extend the gas transmission distance.

[0028] The inner wall of the conical block 202 has a cavity 601, and a heating column 602 is installed inside the cavity 601. A heat-conducting block 603 is connected to the side wall of the heating column 602. The end of the heat-conducting block 603 away from the heating column 602 is fixedly connected to one end of the spiral heat-conducting plate 203. The heat generated by the heating column 602 is conducted to the spiral heat-conducting plate 203 through the heat-conducting block 603, which is used to catalyze heat exchange in the gas contact.

[0029] Working principle: The heating column 602 generates heat, which is conducted to the spiral heat-conducting plate 203 through the heat-conducting block 603. The gas is introduced through the air inlet 3, passes through the transmission space between the outer side of the conical block 202 and the conical groove 201 opened in the lower shell 102, and enters the spiral heat-conducting plates 203 distributed in a ring array on the outer side of the heat-conducting block 603. The gas is transferred in the transmission channel between two adjacent spiral heat-conducting plates 203. In the spiral channel formed by two adjacent spiral heat-conducting plates 203, the contact distance between the gas and the spiral heat-conducting plate 203 is extended, thereby improving the heating and catalytic efficiency.

[0030] If a catalyst is needed, it can be coated on the outer wall of the spiral heat-conducting plate 203;

[0031] After being heated and catalyzed, the gas is transported to the outside of the filter frame 7. The dust in the gas is filtered by the filter screen 701 of the filter frame 7, and the impurities in the gas are adsorbed by the activated carbon 703 before being discharged.

[0032] Specifically: the filter frame 7 includes an inner frame 702, the outer side of the inner frame 702 is wrapped with a filter screen 701, and the space between the inner side of the filter screen 701 and the inner frame 702 is filled with activated carbon 703; an exhaust port 4 is opened at the top inside the inner frame 702, and an air-gathering frame 5 is installed at the top of the inner wall of the exhaust port 4.

[0033] Furthermore: the top of the conical block 202 is fixedly connected to the bottom of the inner frame 702; a conical groove 201 is provided at the bottom of the lower shell 102; a conical space is formed between the outer wall of the conical block 202 and the inner wall of the conical groove 201 for conducting the incoming gas; the diameter of the conical space increases from bottom to top, reducing the gas flow rate and extending the contact time with the spiral heat-conducting plate 203; the gas is introduced through the air inlet 3, passes through the transmission space between the outer side of the conical block 202 and the conical groove 201 in the lower shell 102, and enters the annular array on the outer side of the heat-conducting block 603. In the distributed spiral heat-conducting plates 203, the gas is transported within the transmission channel between two adjacent spiral heat-conducting plates 203. Within the spiral channel formed by two adjacent spiral heat-conducting plates 203, the contact distance between the gas and the spiral heat-conducting plates 203 is extended, thereby improving the heating and catalytic efficiency. At the same time, due to the conical space formed between the outer wall of the conical block 202 and the inner wall of the conical groove 201, the diameter increases from bottom to top, making the inlet channel smaller than the outlet channel. This increases the space and reduces the atmospheric pressure, thereby reducing the gas flow rate and extending the contact time with the spiral heat-conducting plates 203.

[0034] Working principle: The heating column 602 generates heat, which is conducted to the spiral heat-conducting plate 203 through the heat-conducting block 603. The gas is introduced through the air inlet 3, passes through the transmission space between the outer side of the conical block 202 and the conical groove 201 opened in the lower shell 102, and enters the spiral heat-conducting plates 203 arranged in a ring array on the outer side of the heat-conducting block 603. The gas is transmitted in the transmission channel between two adjacent spiral heat-conducting plates 203. In the spiral channel formed by two adjacent spiral heat-conducting plates 203, the contact distance between the gas and the spiral heat-conducting plate 203 is extended, which improves the heating and catalytic efficiency. At the same time, since the diameter of the conical space formed between the outer wall of the conical block 202 and the inner wall of the conical groove 201 increases from bottom to top, the channel at the air inlet end is smaller than the channel at the air outlet end. The space becomes larger and the atmospheric pressure becomes smaller, thereby reducing the gas flow rate and extending the contact time with the spiral heat-conducting plate 203.

[0035] If a catalyst is needed, it can be coated on the outer wall of the spiral heat-conducting plate 203;

[0036] After being heated and catalyzed, the gas is transported to the outside of the filter frame 7, where the dust in the gas is filtered by the filter screen 701, and then the impurities in the gas are adsorbed by the activated carbon 703 before being discharged.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
