[0031] Specifically, an inclined capture plate 3 is provided in the separation chamber 1, which helps to capture and deposit large-sized solid particles when steam passes through, ensuring that they are deposited at the bottom of the separation chamber 1. A concave plate 6 is provided to guide the solid particles deposited at the bottom to be discharged smoothly through the discharge pipe 4, thereby avoiding the accumulation of solid particles in the separation chamber. The situation inside the separation chamber 1 is observed through the observation window 10, and the timing and speed of particle discharge are controlled by controlling the control valve 5 to ensure that it will not affect the normal operation of the main steam system.

[0032] Reference Figure 1 and Figure 3 , the utility model provides an embodiment: the fixing mechanism 7 includes two connecting blocks 701, the inner side of the left connecting block 701 is fixedly connected to the right side of the outer wall of the steam pipe 2, the inner side of the right connecting block 701 is fixedly connected to the left side of the outer wall of the steam pipe 2 9, and the left and right sides of the outer wall of the separation chamber 1 are fixedly connected with connecting blocks 2 702, and the tops of the two connecting blocks 1 701 and the connecting block 2 702 are each provided with a plurality of screw holes 703, and the inner sides of the plurality of screw holes 703 are threadedly connected with bolts 704, and a filter screen 705 is provided on the left side of the inner wall of the steam pipe 2 9; the inner diameter of the screw hole 703 is adapted to the diameter of the bolt 704, and the diameter of the steam pipe 2 and the steam pipe 2 9 is adapted to the inner diameter of the connecting block 2 702; the adjacent sides of the steam pipe 2 and the steam pipe 2 9 are both fixedly connected with a sealing ring 8, and the two sealing rings 8 are slidably connected to the left and right sides of the outer wall of the separation chamber 1.

[0033] Specifically, by providing a filter 705 in the steam pipe 2 9, smaller particles can be filtered, ensuring the purity of the steam and preventing particles from corroding or clogging the inside of the device, thereby extending the service life of the device. The steam pipe 1 2 and the steam pipe 2 9 are connected by the connecting block 1 701 and the connecting block 2 702 under the action of the bolt 704. This design makes the device more convenient during installation and maintenance. In particular, when the filter 705 inside the steam pipe 2 9 needs to be replaced, it can be achieved by simply disassembling the connecting block without disassembling the entire device.

The situation inside the separation chamber 1 is observed through the observation window 10, and the timing and speed of particle discharge are controlled by controlling the control valve 5.
