Embodiment 1

[0014] Embodiment 1: as attached figure 1 As shown, the heat exchanger for reducing butadiene autopolymer includes a shell 1, in which a left tube sheet 2 and a right tube sheet 3 are fixed from left to right, and the left tube sheet 2 and the right tube sheet A heat exchange chamber 4 is formed in the shell 1 between 3, and a row of tubes 5 is distributed in the heat exchange chamber 4. A left head 6 is fixed on the left part of the shell 1, and a right seal is fixed on the right part of the shell 1. The head 7 forms a left chamber between the left head 6 and the left tube plate 2, and the left chamber is fixed with a baffle 10 that divides the left chamber into an upper chamber and a lower chamber 9. There is a butadiene inlet 14 on the top of the corresponding housing 1, and an injection pipe 16 that divides the upper chamber into an inner chamber 17 and an outer chamber 8 is fixed at the butadiene inlet 14. The left ends of the tubes 5 are connected, the outer chamber ...

Embodiment 2

[0017] Embodiment 2: as attached figure 1 Shown, the using method of this heat exchanger that reduces butadiene autopolymer is carried out as follows: when butadiene is in the injection pipe 16, in the column pipe 5, in the right chamber 11 and the lower chamber 9 When more than one place forms self-polymer, butadiene is sent into butadiene inlet 14, injection pipe 16, inner chamber 17, column tube 5 above baffle plate 10, right chamber 11, baffle plate 10 in sequence The column tube 5 and the lower chamber 9 below, finally, butadiene and self-polymer are discharged through the butadiene outlet 15, wherein the pressure of the butadiene is 0.37MPa to 0.38MPa, and the temperature of the butadiene is 40°C To 42°C, the flow rate of butadiene is 5 cubic meters per hour to 14 cubic meters per hour.

[0018] In summary, the present invention can prevent the butadiene autopolymer from entering the dead corner in the heat exchange process, effectively prevent the accumulated buta...

Abstract

The invention relates to the technical field of butadiene heat exchange devices and discloses a heat exchanger for reducing butadiene autopolymer and a using method thereof. The heat exchanger for reducing the butadiene autopolymer comprises a shell, a left tube plate and a right tube plate are fixed inside the shell from left to right, a heat exchange chamber is formed in the portion, between the left tube plate and the right tube plate, of the interior of the shell, tube arrays are distributed inside the heat exchange chamber, and a left gland is fixed on the left portion of the shell. According to the heat exchanger, in the heat exchange process, the butadiene autopolymer can be prevented from entering dead spaces, the gathered butadiene autopolymer is effectively prevented from blocking the heat exchanger for reducing the butadiene autopolymer, it is guaranteed that the heat exchanger for reducing the butadiene autopolymer can conduct heat exchange operation, the heat exchanger for reducing the butadiene autopolymer is prevented from damage due to the fact that the heat exchanger for reducing the butadiene autopolymer is burst to fracture by the butadiene autopolymer, the service cycle of the heat exchanger for reducing the butadiene autopolymer is prolonged, and the adverse effects caused to the production of butadiene rubber are reduced, so that the production efficiency of the butadiene rubber is improved.

Description

technical field [0001] The invention relates to the technical field of butadiene heat exchange devices, and relates to a heat exchanger for reducing butadiene self-polymerization and a use method thereof. Background technique [0002] In the production process of butadiene, butadiene is easy to produce self-polymer in the container because of the self-polymerization characteristic of butadiene. Inhibitors cannot be used in the butadiene production line of the butadiene refining unit, so the heat exchanger in the butadiene production line is prone to produce butadiene self-polymer, because the upper left part of the heat exchanger head Butadiene self-polymers are easy to accumulate in the dead corners. When the accumulation of butadiene self-polymers reaches a certain amount, the self-polymers will block the heat exchanger, resulting in poor extraction, and in severe cases, it may cause heat exchange. The heat exchanger is cracked by butadiene autopolymer, causing damage to ...
