Description

Technical Field

[0001] This utility model relates to the field of gas phase recovery technology, specifically to a product separation and gas phase recovery device for a benzene production unit. Background Technology

[0002] This invention utilizes the adsorption of organic vapors such as benzene by adsorbents for recovery. The gas phase passes through an adsorption bed filled with adsorbents (such as activated carbon or molecular sieves), where benzene and other components are adsorbed, and the purified gas is discharged. After adsorption saturation, the adsorbate is desorbed by methods such as heating and depressurization, achieving adsorbent regeneration and recovery of benzene and other components. Existing benzene production plant product separation and gas phase recovery devices are often difficult to replace when the separation unit is damaged, sometimes requiring the replacement of the entire unit. Furthermore, the activated carbon and other residues generated during benzene absorption by adsorbents are difficult to clean, presenting limitations. To address these issues, a new benzene production plant product separation and gas phase recovery device is proposed.

[0003] CN206566879U discloses a gas phase recovery device, including a reaction vessel, an exhaust pipe, a filter frame, a condenser, a heat insulation cover, an activated carbon adsorption device, a second bend pipe, a second receiving bottle, a first receiving bottle, a first bend pipe, filter cloth, a cold water inlet, a cold water pipe, a cold water outlet, a cap, a drying bottle, and a desiccant. The exhaust pipe is installed on the right side of the reaction vessel, and its right end is connected to the air inlet of the filter frame. More than one filter cloth is installed inside the filter frame, and the air outlet of the filter frame is connected to the first bend pipe. Multiple cold water pipes are installed on the outer periphery of the left side wall of the first bend pipe, and a cold water inlet is provided at the upper end of each cold water pipe. This gas phase recovery device can handle the gases generated in a chemical reaction in a reactor, achieving gas phase recovery.

[0004] Regarding the aforementioned prior art, the inventors believe that the following shortcomings exist: the gas phase recovery device can process the gas generated in the chemical reaction of the batch reactor and realize the gas phase recovery function, but when the separation device is damaged and needs to be replaced, it is difficult to replace or even the entire device needs to be replaced. In addition, the activated carbon and other substances generated when benzene is absorbed by the adsorbent are difficult to clean, which has limitations. Utility Model Content

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0038] Please see Figure 1-4 As shown, this utility model is a product separation and gas phase recovery device for a benzene production unit, including a disassembly and assembly structure 1:

[0039] The disassembly and assembly structure 1 includes a fixed post 101, a fixed base post 102, a spring 103, a telescopic contact 104, and a fixed locking post 105;

[0040] The fixed base post 102 is fixedly connected to the inner side of the fixed post 101, the spring 103 is movably connected to the outer side of the fixed base post 102, the telescopic contact 104 is fixedly connected to one side of the fixed post 101, and the fixed locking post 105 is fixedly connected to the outer side of the fixed base post 102.

[0041] The telescopic contact 104 is connected to the fixed post 101 via the spring 103.

[0042] With the spring 103 in place, when the telescopic contact 104 contacts the upper structure, the spring 103 uses vertical force to make the telescopic contact 104 tightly connected to the upper side. When the telescopic contact 104 is released from the upper side, the spring 103 can reset the two.

[0043] The disassembly and assembly structure 1 also includes a telescopic contact 106, a fixed post 107, a fixed top post 108, and a spring 109;

[0044] Telescopic contact 2 106 is movably connected to one side of telescopic contact 1 104, fixed post 2 107 is fixedly connected to one side of telescopic contact 2 106, fixed top post 108 is fixedly connected to the outside of fixed post 2 107, and spring 2 109 is movably connected to the outside of fixed top post 108.

[0047] The main body 110 of the locking post is fixedly connected to the outside of the fixed top post 108;

[0048] The fixed top post 108 is connected to the fixed post 105 via the post body 110. The outer side of the fixed post 105 and the outer side of the post body 110 are both provided with slots.

[0049] The disassembly and assembly structure 1 also includes a fixed ball 111, a spring 112, and an adjusting column 113;

[0050] The fixed ball 111 is movably disposed in the inner cavity of the locking post body 110, the spring 112 is movably connected to the outer side of the locking post body 110, and the adjusting post 113 is movably disposed on the outer side of the locking post body 110.

[0051] The inner side of the adjusting column 113 is provided with a protrusion.

[0052] By setting the fixed ball 111, when the upper part of the disassembly and assembly structure 1 needs to be snapped with the lower part, the fixed ball 111 can fix the groove on the outside of the snap post body 110.

[0053] The disassembly and assembly structure 1 also includes a limiting ring 114;

[0054] The limiting ring 114 is fixedly connected to the outside of the locking post body 110.

[0055] The limiting ring 114 can limit the adjustment column 113.

[0056] Working principle: When the operator presses the fixing pin 105 to the inside of the pin body 110, the telescopic contact 104 and the telescopic contact 106 come into contact. When the two are pressed together, when the outer groove of the fixing pin 105 comes into contact with the fixing ball 111, the operator can press the adjusting pin 113 down to fix the fixing ball 111 into the groove. At this time, the pressure on the spring becomes a reaction force, making the fixation more stable and tight.

[0057] This step, through the design of disassembly and assembly structure 1, makes disassembly and assembly easier when the internal components of the separation device need to be replaced due to damage.

[0058] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, also includes a pushing structure 2.

[0062] The motor 203 is fixedly connected to one side of the push base plate 201. The push slot 204 is opened on the inner side of the push base column. The stud 205 is movably connected to the inner side of the push slot 204. The push drive block 206 is movably connected to the outer side of the stud 205. The connecting plate 207 is fixedly connected to the upper side of the push drive block 206. The container plate 208 is fixedly connected to the upper side of the connecting plate 207.

[0063] With the arrangement of the holding plate 208, activated carbon can be kept on its upper side and can be transported in and out simultaneously with the holding plate 208.

[0064] Working principle: When the motor 203 starts, it can drive the stud 205 to rotate. When the stud 205 rotates, it can drive the push block 206 to move outside the stud 205. In turn, it can drive the holding plate 208 to move through the connecting plate 207, so that the activated carbon after use can be better transported out and cleaned. By setting the push structure 2, it is convenient to transport and clean the activated carbon after it has been used up, and it is also convenient to place the activated carbon to carry out the reaction.
