Technical Field

[0001] The utility model belongs to the technical field of alkylation reaction product production, and particularly relates to a hot gas recovery device for alkylation reaction product production. Background Art

[0002] In the production process of alkylation reaction products, the hot gas recovery device is an important component. Its main function is to recover the hot gas generated during the reaction process to improve energy utilization efficiency and reduce production costs.

[0003] The existing hot gas recovery device for alkylation reaction product production has the following disadvantages during use: generally, the hot gas is introduced into the water storage tank, and the heat is transferred to the water in the water storage tank through a pipeline for heat recovery and utilization. However, during the recovery process, the intermittent feeding at the top of the alkylation reaction product production device cannot produce a linkage effect with the hot gas recovery, resulting in the need to additionally set an intermittent driving structure on the alkylation reaction product production device to drive the intermittent feeding of the alkylation reaction product. Therefore, a hot gas recovery device for alkylation reaction product production is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hot gas recovery device for alkylation reaction product production to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] As a preferred embodiment, the aerodynamic transmission structure includes a plurality of leaf plates arranged in an annular array and rotatably connected by a rotating shaft inside the air passing cylinder. The hot gas generated by the alkylation reaction product in the reactor will enter the air passing cylinder through the inverted L-shaped air pipe b and drive the plurality of leaf plates to rotate through the rotating shaft.

[0009] Preferably, the intermittent feeding structure includes a turntable fixedly connected to the outer side of the extending part at one end of the rotating shaft, and a transmission column is fixedly connected to the edge of the surface of the turntable.

[0010] Preferably, a transmission rod is movably sleeved outside the transmission column, and a transmission channel matching the transmission column is opened on the transmission rod.

Most of the hot gas generated during the reaction will flow through the air passing cylinder through the inverted L-shaped air pipe b, drive the plurality of leaf plates, and make the turntable connected to the rotating shaft rotate. With the setting of the transmission column, the transmission rod drives the baffle plate to move back and forth on the feeding square pipe, so that the feeding port will intermittently coincide with the inner side of the feeding square pipe, so that the alkylation reaction product in the feeding hopper can intermittently enter the reactor, thus eliminating the need for an additional driving structure to achieve intermittent feeding, and at the same time, the recovery and utilization of hot gas energy can be realized.

[0024] Embodiment

[0025] The existing hot gas recovery device for the production of alkylation reaction products has the following disadvantages during use: Generally, hot gas is introduced into the water storage tank 3, and the heat is transferred to the water in the water storage tank 3 through a pipeline for heat recovery and utilization. However, during the recovery process, the intermittent feeding at the top of the alkylation reaction product production device cannot produce a linkage effect with the hot gas recovery, resulting in the need to additionally set up an intermittent driving structure on the alkylation reaction product production device to drive the intermittent feeding of the alkylation reaction products.

[0026] Therefore, please refer to Figures 1-4The utility model provides a heat recovery device for the production of alkylation reaction products, comprising: a reactor 1 and a water storage tank 3, the reactor 1 and the water storage tank 3 are fixed by a connecting plate 2, a stirring device 5 is installed on the reactor 1, a discharge pipe 11 with a solenoid valve is fixedly connected at the bottom discharge port of the reactor 1, a drainage pipe 35 with a solenoid valve is fixedly connected at the bottom water outlet of the water storage tank 3, a water inlet pipe 36 is also fixedly connected at the water inlet of the outer wall of the water storage tank 3, and an L-shaped valve with a solenoid valve is fixedly connected at the bottom of the water storage tank 3. Exhaust pipe 31, the bottom end of the L-shaped exhaust pipe 31 is connected with a spiral pipe 37, the top end of the spiral pipe 37 is fixedly connected with an inverted L-shaped ventilation pipe a32, the other end of the inverted L-shaped ventilation pipe a32 is fixedly connected with a gas cylinder 33, the air inlet of the gas cylinder 33 away from the inverted L-shaped ventilation pipe a32 is connected to the interior of the reactor 1 through an inverted L-shaped ventilation pipe b34, one side of the stirring device 5 is provided with a feeding square pipe 4 fixedly connected to the feeding port at the top end of the reactor 1, and the top end of the feeding square pipe 4 is fixedly connected with a feeding hopper 41;

[0027] It also includes a pneumatic transmission structure 6 and an intermittent feeding structure 7. The pneumatic transmission structure 6 is installed on the air cylinder 33, and the intermittent feeding structure 7 is installed on the feeding square tube 4 and connected to the pneumatic transmission structure 6.

[0028] Further as Figures 1-4 As shown, it is worth specifically explaining that in order to be able to use the flow rate of hot air entering the spiral pipe 37 to drive the multiple leaf plates 62 to rotate, a pneumatic transmission structure 6 is set up, including a plurality of leaf plates 62 arranged in a ring array and rotatably connected by a rotating shaft 61 on the inner side of the air cylinder 33. The hot gas generated by the alkylation reaction product in the reactor 1 will enter the air cylinder 33 through the inverted L-shaped ventilation pipe b34, and drive the multiple leaf plates 62 to rotate through the rotating shaft 61.

[0029] Further as Figures 1-4 As shown, it is worth explaining in detail that in order to enable the above-mentioned multiple leaf plates 62 to be driven by the force of the hot gas flow, so that the alkylation reaction product materials in the feeding hopper 41 can be intermittently fed into the reactor 1, an intermittent feeding structure 7 is provided, which includes a turntable 71 fixed to the outer side of the extension portion of one end of the rotating shaft 61, and a transmission column 72 is fixed to the surface edge of the turntable 71.

[0030] The width of the transmission channel is equal to the diameter of the transmission column 72, and the length of the transmission channel is greater than the diameter of the turntable 71.

[0031] In summary, when using the hot gas recovery device for producing alkylation reaction products, during the first feeding, the baffle 74 can be manually pushed to the state where the feeding port 75 is aligned with the inner side of the feeding square pipe 4, and the alkylation reaction products for the reaction are put into the reaction kettle 1 for reaction stirring. Most of the hot gas generated during the reaction will flow through the inverted L-shaped gas pipe b34 and pass through the gas cylinder 33, and drive multiple leaf plates 62, and cause the turntable 71 connected to the rotating shaft 61 to rotate. With the arrangement of the transmission column 72, the transmission rod 73 drives the baffle 74 to move back and forth on the feeding square pipe 4, so that the feeding port 75 will intermittently coincide with the inner side of the feeding square pipe 4, so that the alkylation reaction products in the feeding hopper 41 can intermittently enter the reaction kettle 1, so that there is no need for an additional driving structure to achieve intermittent feeding, and at the same time, the recovery and utilization of hot gas energy can be realized.
