[0002] After water is converted into steam and during its use and production, the steam may carry impurities such as scale particles and fibers. These impurities not only affect the purity of the steam but may also damage subsequent production and processing equipment. Filtration is necessary to ensure the steam is clean and meets the requirements of subsequent production and processing. Currently, most methods use metal filters to purify the steam. However, after a certain period of use, metal filters are prone to clogging. Clogging reduces steam flow, thus affecting production efficiency. This necessitates shutdown, disassembly, and cleaning of the filter, which not only reduces production efficiency but also presents difficulties in disassembling and assembling the metal filter, being time-consuming and labor-intensive, and failing to meet the requirement of continuously clean steam.

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0031] like Figure 1-9The illustration shows a steam purifier according to this embodiment. This steam purifier is connected to a steam generator and achieves steam purification by filtering the input steam. The steam purifier includes a cylindrical body 1. The cylindrical body 1 has a cylindrical structure and a length extending along a first direction. In this embodiment, the first direction is the vertical direction. Specifically, the cylindrical body 1 includes a hollow main body 11, a top cover 13, and a bottom cover 12. The hollow main body 11 has open ends. The top cover 13 is bolted to the first end of the hollow main body 11, and the bottom cover 12 is bolted to the second end of the hollow main body 11, forming an internal chamber within the cylindrical body 1. A partition 2 extending along the first direction is installed inside the hollow main body 11. This partition 2 divides the inner cavity of the cylindrical body 1 into two clean chambers 6, left and right. Specifically, slots 110 extending in the first direction are machined on the inner walls of opposite sides of the hollow body 11 of the cylinder 1, and the two sides of the partition 2 are inserted into the slots 110 to allow for disassembly.

[0032] In this embodiment, the partition 2 has a mating end face facing each clean chamber 6. Two independent flow channels 21 are machined inside the partition 2 to supply water for flow within the flow channels 21. One flow channel 21 is arranged corresponding to each mating end face. A water nozzle 3, communicating with the corresponding flow channel 21, is installed on the mating end face. The water nozzle 3 is threadedly connected to the partition 2. A water inlet pipe 5 is arranged on the partition 2 corresponding to each flow channel 21. The water inlet pipe 5 communicates with the flow channel 21, and one end of the water inlet pipe 5 is threadedly connected to the partition 2. The water inlet pipe 5 has a water inlet end exposed outside the cylinder 1. An external water pipe is connected to the water inlet end of the water inlet pipe 5 to supply water flow to the water inlet pipe 5. The water flow passes through the flow channel 21 and is then sprayed out through the water nozzle 3. A perforation 17 is machined on the aforementioned top cover 13 corresponding to each water inlet pipe 5. The water inlet pipe 5 is inserted into the perforation 17 to extend to the outside of the cylinder 1. A rubber sealing part 18 is installed between the perforation 17 and the water inlet pipe 5 to close the gap between the perforation 17 and the water inlet pipe 5 and prevent steam leakage. The water inlet ends of the two water inlet pipes 5 are connected to the water supply device through a three-way valve. By switching the three-way valve to different positions, water can be delivered to the two water inlet pipes 5 respectively.

[0033] Each clean chamber 6 is equipped with an orifice plate 4 extending along a first direction. The orifice plate 4 and the partition plate 2 enclose a steam outlet chamber 61, and the orifice plate 4 and the cylinder 1 enclose a steam inlet chamber 62. The spray nozzle 3 is arranged with its spray end facing the orifice plate 4. In this embodiment, two grooves extending along the first direction are machined on the side of the partition plate 2 facing the clean chamber 6. The two ends of the orifice plate 4 in the width direction (perpendicular to the first direction) are inserted into the grooves for detachable installation on the partition plate 2. A plurality of filter holes 41 are distributed on the orifice plate 4. The filter holes 41 are designed to filter steam. On the top surface of the cylinder 1 (i.e., on the top cover 13), a steam outlet 16 communicating with each steam outlet chamber 61 is machined. On the side wall of the hollow body 11 of the cylinder 1, a steam inlet 19 communicating with each steam inlet chamber 62 is machined. With the above structural design, steam enters the steam inlet chamber 62 through the steam inlet 19, passes through the orifice plate 4 into the steam outlet chamber 61, and is then discharged through the steam outlet 16.

[0034] In this embodiment, a switch control valve body is installed on each steam inlet 19. The opening and closing of the valve body is controlled by the control switch to realize the opening and closing of the steam inlet 19.

[0035] In the specific structural design, the tops of the partition plate 2 and the perforated plate 4 are in contact with or clearance fit with the inner top surface of the cylinder 1, and the bottoms of the partition plate 2 and the perforated plate 4 are in contact with or clearance fit with the inner bottom surface of the cylinder 1. Preferably, in this embodiment, during specific assembly, the aforementioned partition plate 2 and the perforated plate 4 abut against the top cover 13 and the bottom cover 12.

[0036] The bottom edge of the orifice plate 4 is machined with several notch structures 42 that connect the steam inlet chamber 62 and the steam outlet chamber 61. Through these notch structures 42, water accumulated in the steam outlet chamber 61 can enter the steam inlet chamber 62 through the notch structures 42 and flow into the water inlet channel 14.

[0037] The inner bottom surface of the cylinder 1 (i.e., the end face of the bottom cover 12 facing the clean chamber 6) is machined with a water inlet groove 14 corresponding to the steam inlet chamber 62. This water inlet groove 14 extends along an arc and has two ends along its length. The two ends of the water inlet groove 14 have a height difference in a first direction. The first end of the water inlet groove 14 is closer to the steam inlet chamber 62 in the first direction, while the second end is farther away from the steam inlet chamber 62 in the first direction. A drain hole 15 is machined on the bottom cover 12, communicating with the second end of the water inlet groove 14. When water accumulates in the clean chamber 6, the water enters the water inlet groove 14, moves towards the drain hole 15, and is discharged through the drain hole 15. In this embodiment, a switch valve is connected to the drain hole 15 to control its opening and closing.

[0038] In this embodiment, the partition 2 is installed inside the cylinder 1 by plugging it in, and the perforated plate 4 is installed on the partition 2 by plugging it in, so as to facilitate the disassembly and maintenance of the partition 2 and the perforated plate 4.

[0039] In practical use, steam enters the steam inlet chamber 62 through two steam inlets 19, is filtered by the perforated plate 4, enters the steam outlet chamber 61, and is discharged through the steam outlet 16. Condensate generated during steam transport flows into the water inlet groove 14 and is discharged through the drain hole 15. When one side of the perforated plate 4 is blocked or during periodic cleaning, the steam inlet 19 on that side is closed, while the steam inlet 19 on the other side remains open. Water is supplied to the corresponding water inlet pipe 5 on that side, and the water is sprayed from the nozzle 3 through the flow channel 21 to flush and clean the perforated plate 4. The impurities flushed down are guided by the water inlet groove 14 and discharged through the drain hole 15. In this method, the perforated plate 4 filters out impurities carried by the steam, achieving steam purification. The water spraying from the nozzle 3 flushes down impurities on the perforated plate 4 and guides them out through the water inlet groove 14, preventing impurities from accumulating inside the cylinder 1. By alternately closing the steam inlet 19 on one side, normal steam delivery is ensured without affecting the cleaning of the orifice plate 4 on the other side. This allows for cleaning of the orifice plate 4 without shutting down the machine, effectively preventing blockage, saving time and effort, and guiding the cleaned impurities out of the cylinder 1, effectively meeting the operational requirements for continuous clean steam.
