[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0012] Example Reference Figures 1-4 A steam washing device for steam includes a steam inlet pipe 5, and the steam washing device further includes: Steam scrubbing tower 6 is located below steam inlet pipe 5, and the bottom end of steam inlet pipe 5 extends into the interior of steam scrubbing tower 6 and is fixedly installed between them. Steam inlet 4 is opened at the top of steam inlet pipe 5, steam outlet 8 is opened on the left side of steam scrubbing tower 6, and packing cleaning port 9 is provided inside steam outlet 8. Water inlet 10 and volute water inlet 11 are opened on the left side of steam scrubbing tower 6 respectively, and water outlet 12 is opened at the bottom of steam scrubbing tower 6. Demister 13 is installed on the inner wall of steam washing tower 6 and is sleeved on steam inlet pipe 5. Test lens 15 is installed on steam scrubber 6; The spray assembly includes a first spray port 1, a second spray port 2, and fourteen solid nozzles 3. The first spray port 1 and the second spray port 2 are both installed inside the steam inlet pipe 5. The first spray port 1 is located above the second spray port 2. The left ends of the first spray port 1 and the second spray port 2 both penetrate the left inner wall of the steam inlet pipe 5 and extend to the outside of the steam inlet pipe 5. The seven solid nozzles 3 located above are fixedly connected to the bottom of the first spray port 1 in a ring at equal intervals, and the seven solid nozzles 3 located below are fixedly connected to the bottom of the second spray port 2 in a ring at equal intervals.

[0013] To provide stable support for the steam washing tower 6, four support legs 14 are fixedly installed at the bottom of the steam washing tower 6.

[0014] To facilitate the observation of the liquid level inside the steam washing tower 6, a first liquid level gauge 7 is installed on the right side of the steam washing tower 6, and a second liquid level gauge 17 is installed at the bottom of the steam washing tower 6.

[0015] In order to provide stable support for the second liquid level gauge port 17, a fixing rod 16 is fixedly installed on the top of the second liquid level gauge port 17, and the top end of the fixing rod 16 is fixedly installed on the bottom of the steam washing tower 6.

[0016] The working principle of this utility model is as follows: In use, the steam inlet pipe 5 is first equipped with multiple layers of spray. The bottom of the first spray port 1 and the second spray port 2 both contain spray ports and multiple solid nozzles 3 arranged in a ring. The multiple solid nozzles 3 of each layer distribute the detergent (acid, alkali or water) evenly into the steam inlet pipe 5 as much as possible. In order to prevent dead corners, multiple layers of spray are set up, and the positions of the solid nozzles 3 of each layer are arranged in a ring and cross each other to ensure that every part of the steam inlet pipe 5 can be sprayed. Then, the steam-liquid mixture after washing is separated in the steam washing tower 6. The separated gas is discharged after being demisted by the demister 13, and the liquid is discharged through the water inlet and outlet 12. In order to avoid the demister 13 from being blocked, the demister 13 is equipped with a ring packing cleaning port 9 to facilitate the cleaning of the demister 13.
