[0018] like Figure 1 As shown, a steam purification device includes a purification reactor 1, made of steel with a pressure resistance test exceeding 25 kg. All internal components are made of 304 or higher grade stainless steel to reduce pollution generated by the equipment itself. The bottom of the purification reactor 1 has an inverted conical collecting section 2, and the bottom of the collecting section 2 has a discharge port 15 with a valve 17. Several magnets 3 are adsorbed on the outer wall of the collecting section 2 to adsorb tiny iron dust particles. The magnets 3 are removed each time the filter screen 13 is backwashed, and the adsorbed impurities are discharged with the washing water. The lower middle part of the purification reactor 1 has a steam inlet 4, and the top has a steam outlet 5. Both the steam inlet 4 and the steam outlet 5 are equipped with pressure gauges 16 and valves 17. The purification reactor 1 is equipped with a rotating support inside. The rotating support includes a lower support plate 6 with filter holes located in the collecting section 2 and an upper support plate 7 with filter holes located above the purification reactor 1. A rotating shaft 8 is rotatably mounted on the central axis between the lower support plate 6 and the upper support plate 7. Rotary bearings are provided between the rotating shaft 8 and both the lower support plate 6 and the upper support plate 7. The rotating shaft 8 is equipped with helical blades 9, which have a spiral downward spiral structure to facilitate the settling of heavy particles and condensate. The blade 9 is four-fifths the height of the entire device, and the distance from the side wall is about two millimeters. A water inlet pipe 10 is provided near the lower part of the steam outlet 5. A valve 17 is provided on the water inlet pipe 10. A nozzle 11 is provided at the end of the water inlet pipe 10 that extends into the purification reactor 1 to clean the clogged filter screen 13. A sealing plate 12 with a central opening is provided at the lower part of the nozzle 11 and is fixed in the purification reactor 1.

[0019] Working principle: the utility model provides a kind of steam purification device, when using, first open steam outlet 5 valve 17, then open steam inlet valve 17, let steam slowly enter the inside of purification reaction kettle 1.Spiral blade 9 rotates clockwise by steam flow force, iron particles, other hard particles and water in steam are settled due to gravity and spin page down force.Volume and mass small iron-containing particles are adsorbed by magnet 3 located at the bottom of material collecting section 2, and fall into the bottom of the device.Dust not settled and magnetically adsorbed is blocked by fine mesh filter, and particles, rust and condensed water in steam can be effectively removed after three times of filtration.

[0020] In the operation of the device, the filtration effect is determined by observing the pressure gauge 16 values of steam inlet 4 and steam outlet 5.According to the size of filter mesh, the pressure difference between inlet and outlet of the device is different, the denser the filter mesh, the greater the pressure difference, usually in the range of 0.02~0.05mpa.If the pressure difference of steam outlet 5 is greater than the calibrated value, it means that the number of impurities in the internal filter is large, and it needs to be cleaned, and the backflushing device can be opened for flushing.

[0021] The device is suitable for various production processes and fine processing projects, and the size of the device can be assembled according to the actual needs of the site;the fineness of filtration can be adjusted by the mesh number of filter 13 and the height of elongated spin page;bottom valve 17 is automatic water delivery type, and timing device can also be installed to realize discharging on time.Through the above three ways of filtration, the quality of steam can be effectively purified.

[0022] The device can effectively settle and collect iron and calcium particles in steam, prevent them from entering the material or equipment inside;separate water from steam to obtain dry steam with low water content;for high-quality processing projects, the subsequent impurity removal and purification process is eliminated;easy to install, clean and maintain.
