[0002] The function of a demister is to remove liquid foam from the gas to prevent the loss of useful products or contamination of condensed liquids. Foam ceramics are often used in chemical applications instead of traditional stainless steel wire mesh demisters due to their high temperature and corrosion resistance.

[0024] Example 1

[0025] See also Figures 1 to 6 The utility model provides the following technical solutions: a corrosion-resistant defoaming device, which is suitable for defoaming in structures such as sulfuric acid towers using foam ceramics.

[0026] Specifically, if Figures 1 to 6 As shown, a corrosion-resistant defoaming device includes a multi-layer foam ceramic wire mesh 1, an annular frame 2, a multi-layer building block group 3 and a positioning component 4; the multi-layer building block group 3 is staggered from the bottom of the annular frame 2 to the top of the annular frame 2; the foam ceramic wire mesh 1 is mounted on the top of the building block group 3; one end of the positioning component 4 is embedded in the annular frame 2 and extends toward the building block group 3.

[0027] In this embodiment, the multi-layer foam ceramic screen 1 is fixed by the multi-layer block group 3. During installation, the spacing between the multi-layer block groups 3 is controlled to control the working distance between the foam ceramic screens 1. After the multi-layer foam ceramic screen 1 is supported by the multi-layer block group 3, it is uniformly embedded and pressed by the positioning component 4 to achieve fast and uniform fixation. The entire installation process is fast and efficient. During disassembly, only the positioning component 4 needs to be removed, and then the multi-layer foam ceramic screen 1 and the multi-layer block group 3 need to be pulled out by lifting the entire annular frame 2, and then the entire annular frame 2 can be tilted, knocked, etc., so that quick disassembly can be achieved.

[0028] Specifically, if Figure 1 As shown, the building block set 3 includes a pair of building blocks; the building blocks are magnetically connected to the inner wall of the annular frame 2.

[0029] Specifically, if Figure 1 As shown, the building block set 3 includes a pair of building blocks; the building blocks are screwed to the frame wall of the annular frame 2.

[0030] In this embodiment, by using magnet blocks in conjunction with the magnet annular frame 2, or screw hole blocks in conjunction with the screw hole annular frame 2, the multi-layer foam ceramic screen 1 can be installed and efficiently removed according to the defoaming requirements.

[0031] Specifically, if Figures 1 to 6As shown, a pair of building blocks are each provided with an open limiting groove; a supporting strip 5 is provided between the pair of building blocks; and the end of the supporting strip 5 is embedded in the open limiting groove.

[0032] In this embodiment, each layer of blocks can be made of a pair and a single support strip 5. At the same time, the support strips 5 of each layer have different inclination directions to reduce the weight of the demister device as a whole and ensure overall stability.

[0033] In this embodiment, a first flange ring plate 21 is provided on the top of the annular frame 2; the positioning assembly 4 includes a pressure piece and a second flange ring plate 41; one end of the pressure piece is embedded in the annular frame 2; the other end of the pressure piece is connected to the second flange ring plate 41; the first flange ring plate 21 and the second flange ring plate 41 are screwed together.

[0034] In this embodiment, the pressing member may be a plurality of pressing blocks or a pressing cylinder with a certain thickness.

[0035] Specifically, if Figures 1 to 6 As shown, the apparatus further includes a flow guide assembly 6; an annular frame 2 is embedded in the inner cavity of the flow guide assembly 6. The flow guide assembly 6 includes an outer frame 61, a flow guide hopper 62, and a liquid guide tube 63. The annular frame 2 is embedded in the top interior of the outer frame 61; the bottom of the outer frame 61 is connected to the flow guide hopper 62; the expanded end of the flow guide hopper 62 is provided with multiple ventilation holes; and the liquid guide tube 63 is connected to the contracted end of the flow guide hopper 62.

[0036] In this embodiment, when performing the defoaming operation, the fluid enters from the multiple air holes of the guide bucket 62, and the foam in the fluid is effectively captured and attached to the wire mesh through the multi-layer foam ceramic wire mesh 1. As the fluid continues to flow, the foam gradually forms a thin film on the wire mesh. Due to the surface tension of the wire mesh and the action of fluid dynamics, this thin film gradually breaks and releases the liquid inside. The liquid is guided to the liquid guide tube 63 through the guide bucket 62 and discharged through the liquid guide tube 63.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
