Description

European and metallurgical furnace gas demister with fixed structure
Technical Field
The utility model relates to a foam remover for a European and metallurgical furnace gas with a fixed structure.
Background
The European smelting furnace flow is one of the most advanced non-blast furnace iron-making processes in the current and the future for a certain period, and according to the technological parameter requirements of a decarburization recycling compressor, the European smelting furnace gas needs to be cooled and dehydrated and then is pressurized and recycled to the European smelting furnace gasification furnace. After cooling, a large amount of saturated water is separated out, and before compression, a gas-liquid separator is needed to discharge the separated mechanical water. At present, many gas-liquid separators adopt a silk screen foam remover to remove foam, the silk screen foam remover mainly comprises a silk screen, a silk screen grating and a supporting device for fixing the silk screen block, the silk screen is a gas-liquid filter screen made of various materials, the gas-liquid filter screen is composed of metal wires or nonmetal wires, when the silk screen is replaced, the silk screen block is required to be removed one by one according to the silk screen grating area, and new silk screen blocks are replenished, so that the device is very troublesome, inconvenient to maintain, uneven tiling is easy to cause, and normal production is affected.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides the European and metallurgical furnace gas demister with a fixed structure, which is convenient to replace and maintain.
The technical scheme adopted by the utility model is as follows: the utility model provides a ohm stove coal gas demister with fixed knot constructs, which comprises a housin, evenly set up bottom baffle ring support piece on the casing bottom inner peripheral wall, set up silk screen section of thick bamboo and bottom baffle ring respectively on this support piece from outside to inside, bottom grid has in the bottom baffle ring, grid packing is being set up in proper order from bottom to top in the silk screen section of thick bamboo of bottom grid top, middle level silk screen packing, upper silk screen packing and top grid, top grid periphery constitutes the top clamping ring, evenly the interval is setting up the briquetting that has the screw on the top inner peripheral wall of silk screen section of thick bamboo, the top clamping ring is also evenly the interval setting up the screw, link together through the bolt between briquetting and the top clamping ring, grid packing thickness is 90-180mm, upper strata and middle level silk screen packing thickness are 80-130mm respectively.
This demister has set up 3 layers of packing, and upper strata and middle level are silk screen packing, and the lower floor is the grid packing of taking cuboid net runner, and the gas that contains liquid foam and solid particle flows from bottom to top, loops through grid packing and silk screen packing, carries out 3 grades and removes the foam through 3 sections different structural style's packing, and the foam removal effect is better. The grid filler is arranged below the two layers of screen fillers at the upper part, when the Europe furnace gas containing mechanical water and the particulate matters of solid impurities passes through the grid filler, the Europe furnace gas flows in the rectangular three-dimensional grid runner, and cannot be entrained to the screen fillers above the grid filler by the Europe furnace gas, so that the screen is prevented from being blocked by the solid particles, and the particulate matter removing effect of the solid impurities is strong. The two layers of silk screen filler are arranged above the grid filler, the mechanical water silk screen filler layer of the European and metallurgical furnace gas which is not removed by the grid filler is subjected to fine filtration, and the upper middle silk screen is subjected to thickness size adjustment according to defoaming efficiency. The thickness of the grid filler is 90-180mm, and the thickness of the silk screen filler is 80-130mm, so that the optimal defoaming effect can be obtained.
The upper portion of the silk screen packing is provided with a top pressing ring, the upper portion of the top pressing ring is respectively provided with 2 groups of top grating plates by taking the central diameter as a reference, the circumference of the top pressing ring is uniformly provided with bolt holes, the top pressing ring is connected with the bolt holes in a pressing block arranged on the silk screen cylinder by bolts, and the pressing block can adjust the upper and lower heights according to the thickness of the silk screen.
Adopt bolted connection, with the effectual fixed of filler, dismantle convenient, easy operation. Therefore, the utility model has better anti-blocking performance, can prolong the service life, is easy to replace the silk screen, occupies less time and has high efficiency. The three-layer filler is arranged, so that the European smelting furnace gas containing the mechanical water and the solid impurity particles flows from bottom to top, sequentially passes through the grid filler and the wire mesh filler, performs three-level defoaming, has a good defoaming effect, and simultaneously avoids the blockage of the wire mesh by the solid particles. The filler is effectively fixed by the bolt connection, so that the disassembly is convenient, and the operation is simple. The utility model realizes the adjustment of the upper, middle and lower layers of silk screens structurally, has convenient assembly and disassembly and high efficiency, provides great convenience for practical application, has good defoaming effect, is not easy to block the silk screens, and can be widely applied to the field of impurity removal of metallurgical gas.
