From the first steam supply branch pipe 44, a first steam supply branch pipe 441 which leads into the 1# kettle 11 and a second steam supply branch pipe 442 which leads into the 2# kettle 12 are separated. From the second steam supply branch pipe 46, a third steam supply branch pipe 463 leading into the 3# kettle 13 and a fourth steam supply branch pipe 464 leading to the 4# kettle 14 are separated.

[0011] A main steam supply valve 444 is installed on the first steam supply branch pipe 44, and a steam supply pipeline trap group 446 is installed before the main steam supply valve 444. A steam-actuated shut-off valve 4412 is installed on the first steam supply branch pipe 441, and a normally open plunger shut-off valve 4414 is installed before the steam-actuated shut-off valve 4412. A pneumatic shut-off valve 4422 is also installed on the second steam supply branch pipe 442, and a normally open plunger shut-off valve 4424 is installed before the pneumatic shut-off valve 4422. A stop valve 4632 is installed on the third steam supply branch pipe 463. A stop valve 4642 is installed on the fourth steam supply branch pipe 464.

[0012] A steam dumping main pipe 52 is arranged between the four autoclaves and the eight steaming tanks. The steam dumping main pipe 52 is divided into a first steam dumping branch 54 and a second steam dumping branch 56 at one end adjacent to the autoclave. A first steam reverse branch pipe 541 connected from the 1# kettle 11 and a second steam reverse branch pipe 542 connected from the 2# kettle 12 are separated from the first steam reverse branch pipe 54. A third steam dump branch pipe 563 connected from the 3# kettle 13 and a fourth steam dump branch pipe 564 connected from the 4# kettle 14 are separated from the second steam dump branch pipe 56.

[0013] A shut-off valve 5412 is installed on the first steam reverse branch pipe 541. A stop valve 5422 is installed on the second steam reversing branch pipe 542. A shut-off valve 5632 is installed on the third steam reversing branch pipe 563. A shut-off valve 5642 is installed on the fourth steam reversing branch pipe 564.

[0014] One end of the steam dumping main pipe 52 adjacent to the steaming tank is divided into a first steam inlet branch 581 leading to 1# pool 21, a second steam inlet branch 582 leading to 2# pool 22, and a third steam inlet branch leading to 3# pool 23. Steam branch 583, one to the fourth steam branch 584 of 4# pool 24, one to the fifth steam branch 585 of 5# pool 25, one to the sixth steam branch 586 of 6# pool 26, and one to enter 7# The seventh steam inlet branch 587 of pool 27, and the eighth steam inlet branch 588 of 8# pool 28.

[0015] A shut-off valve 5812 is installed on the first steam inlet branch pipe 581. A stop valve 5822 is installed on the second steam inlet branch pipe 582. A shut-off valve 5832 is installed on the third steam inlet branch 583. A shut-off valve 5842 is installed on the fourth steam inlet branch 584. A shut-off valve 5852 is installed on the fifth steam inlet branch 585. A shut-off valve 5862 is installed on the sixth steam inlet branch 586. A stop valve 5872 is installed on the seventh steam inlet branch 587. A shut-off valve 5882 is installed on the eighth steam inlet branch 588.

[0016] A steam supply main pipe 62 is provided from the boiler room sub-cylinder 3 to the eight steam curing tanks, and a stop valve 64 is installed on the steam supply main pipe 62. One end of the steam supply main pipe 62 adjacent to the steaming tank is divided into a first steam supply branch 621 leading to 1# pool 21, a second steam supply branch 622 leading to 2# pool 22, and a third steam supply branch leading to 3# pool 23. The steam branch 623, the fourth steam supply branch 624 of one access to 4# pool 24, the fifth steam supply branch 625 of the 5# pool 25, the sixth steam supply branch 626 of the 6# pool 26, and the one access 7# The seventh steam supply branch 627 of pool 27, and the eighth steam supply branch 628 of 8# pool 28.

[0017] A shut-off valve 6212 is installed on the first steam supply branch 621. A shut-off valve 6222 is installed on the second steam supply branch 622. A shut-off valve 6232 is installed on the third steam supply branch pipe 623. A stop valve 6242 is installed on the fourth steam supply branch pipe 624. A stop valve 6252 is installed on the fifth steam supply branch 625. A shut-off valve 6262 is installed on the sixth steam supply branch pipe 626. A stop valve 6272 is installed on the seventh steam supply branch 627. A stop valve 6282 is installed on the eighth steam supply branch pipe 628.

[0018] The present invention makes the greatest possible secondary utilization of the decompression waste steam from the autoclave and saves energy; the steam supply and reversal pipelines of the autoclave are equipped with pipeline trap groups to avoid water hammer phenomenon during steam supply and prevent The pipeline is damaged; when the steam-actuated shut-off valve of 1# kettle, 2# kettle or the main steam pipeline is defective and needs to be dealt with, it is no longer necessary to close the steam supply main valve.
