The fixed frame 201c is movable in the filter box 201a, the double-layer filter screen 201d is fixed on the fixed frame 201c, and the sealing ring 201e is fixed on both the placement box 201b and the fixed frame 201c.

[0033] The setting of the fixing frame 201c is used to fix the double-layer filter screen 201d, so that the double-layer filter screen 201d can filter the water droplets passing through the activated carbon particles again. The setting of the sealing ring 201e is used to increase the sealing between the fixing frame 201c and the placement box 201b and the filter box 201a.

[0034] Example 3

[0035] Reference Figure 1~Figure 3 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0036] Specifically, the circulation component 202 includes a collection box 202a, a water pump 202b and a circulation pipe 202c. The collection box 202a is fixed to the bottom of the filter box 201a, the water pump 202b is fixed to the collection box 202a, and both ends of the circulation pipe 202c are fixedly connected to the water inlet 102 and the water pump 202b respectively.

[0037] The collecting box 202a is provided to collect the filtered water droplets, and the water pump 202b is provided to transport the collected water back to the water inlet 102 through the circulation pipe 202c, and then transport it to the high-pressure preheater body 101 for preheating.

[0039] The first solenoid valve 202d is used to control the closing and opening of the water inlet 102 and the water outlet 103, thereby maintaining the pressure in the high-pressure steam preheater body 101. The second solenoid valve 202e is used to control the opening and closing of the circulation pipe 202c.

After the water level reaches the requirement, the water level temperature detector 202f will control the first solenoid valve 202d on the water inlet 102 to close, and then water vapor will enter the high-pressure steam preheater body 101 through the air inlet 104, thereby increasing the temperature of the high-pressure steam preheater body 101 and entering the high-pressure steam preheater body 101. The temperature of the water vapor in the pre-heater body 101 will decrease, and then condense into water droplets and adhere to the inner wall of the high-pressure pre-heater body 101, and then fall into the filter box 201a through the air outlet 105. When passing through the activated carbon particles in the placement box 201b, the activated carbon particles will adsorb the dust or toxic substances carried by the water droplets attached to the inner wall of the high-pressure pre-heater body 101, and then the water droplets will fall onto the double-layer filter mesh 201d, and the double-layer filter mesh 201d will filter the activated carbon debris carried in the water droplets, and finally fall into the collection box 202a for collection.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
