Heat exchanger for reducing butadiene autopolymer and using method thereof

[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 8 i

[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 butadie
