Description
The present invention relates to a kind of demister, particularly a kind of wire mesh demister, belong to petrochemical industry, thermoelectricity field.
Background technology
When operating gas velocity is larger in tower, there will be tower top entrainment, this not only causes the loss of material, also makes the efficiency of tower reduce, also may cause the pollution of environment simultaneously.In order to avoid this situation, need to arrange Despumation device at tower top, thus reduce the entrainment loss of liquid, guarantee the purity of gas, ensure the normal operating of follow-up equipment., all there are some defects in Despumation device common at present, as standard type wire mesh demister, its shortcoming be higher in gas speed or local stoppages time easily produce reentrainment; Baffle plate demister, its because of resistance drop comparatively large, range of application is limited; Packing section for removing foam device, in tower, space hold is large, and during installation, program is complicated, and material cost is higher.Wave silk screen foam remover disclosed in Chinese patent CN2305241Y, the waveform silk screen block be combined into after mold pressing primarily of silk screen grid, silk screen composition, the bottom-valley that the liquid under demister can be made to remove is flowed to rapidly waveform silk screen block is concentrated, after forming large drop lower.Material is thus formed and make gas circuit leave with rage, shunting mode that liquid walks fluid path, decrease reentrainment; Both can increase foam removal effect, turn increase foam removal area.Problems existing has two.One is only use silk screen filter, and foam removal effect is poor; Two is that in gas, solid content is higher, silk screen is easily blocked by solid particle.The disclosed a kind of easily replacing formula wire mesh demister of Chinese patent CN202823016U, support ring outer shroud side connects the cylinder inboard wall of vertical separation equipment.Bolt connects support ring end face.Silk screen is placed on support ring end face through bolt.Shelves bar is placed on silk screen other end, and by the Bolt to position through the end prebored hole of shelves bar, bolt is fixed by nuts and washers.Structure is simple, run into road conditions not good time, inner screen can not be subjected to displacement, more can not separation instrumentation.Simple structure of the present invention, change silk screen mounting or dismounting convenient, only need simple operations to complete, few when accounting for, efficiency is high.This Combined defoamer also has problems, and the foam removal of individual layer silk screen may have a small amount of entrainment, and gas purity can not ensure, although be bolt connection, installation difficulty is large.
The present invention is exactly the deficiency that will overcome existing demister, provides a kind of novel wire mesh demister.This novel wire mesh demister, to solve, the foam removal effect that existing demister exists respectively is poor, silk screen is easy to that blocking, structure are comparatively complicated and manufacture difficulty is comparatively large, need the independently problem such as installing space.Effectively can remove the drop or suspended impurity that carry in gas, realize gas-liquid separation.Its structure is simple, installation and repairing convenient, resistance drop is little, cost is low, and adjusting function is good, stable operation, is convenient to commercial introduction.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of novel wire mesh demister, this wire mesh demister is provided with double-deck filler, upper strata is the grid packing of band cube grid runner, lower floor is wire packing, gas containing liquid foam and solid particle flows from bottom to top, successively by grid packing and wire packing, carry out two-stage foam removal by the filler of two sections of different structure forms, foam removal effect is better.When gas containing liquid foam and solid particle is by grid packing, flow in stereoscopic grid runner, after contained large drop and solid particle encounter stripe board, can accumulate in stripe board, in time accumulating to a certain degree, liquid and solid particle slide along stripe board, can not be entrained on the wire packing above grid packing by gas, doing so avoids solid particle blocking silk screen.With bolts, filler is effectively fixed, convenient disassembly, simple to operate.Therefore, the present invention has good performance of anti-blockage, can increase the service life, and change silk screen mounting or dismounting easily, few when accounting for, efficiency is high.
In order to solve the problem, the present invention is achieved through technology,
A kind of novel wire mesh demister, comprises top board, wire packing, bolt, nut, upper support ring, grid packing, gripper shoe and lower support ring.Upper support ring and lower support ring are welded on inside cylindrical shell respectively; Be fixedly connected with bolt between top board with upper support ring, be fixedly connected with bolt between gripper shoe with lower support ring; Top board and gripper shoe size are all slightly less than cylinder internal diameter; Grid packing is the packing layer of band stereoscopic grid runner, is made up of stripe board in a row, and adjacent two row's stripe board are contrary with the incline direction of horizontal plane and mutually intersect, and the stripe board in same row's stripe board is parallel to each other.Grid packing is placed in the below of wire packing, when the gas containing liquid foam and solid particle is by grid packing, first flows in stereoscopic grid runner, can not be entrained on the wire packing above grid packing by gas, doing so avoids solid particle blocking silk screen, foam removal effect is strong.
Pressing plate and gripper shoe and cylindrical shell with bolts, silk screen easy accessibility, efficiency is high.
Double-deck filler, grid packing is placed in the below of wire packing, preferential filtering solid particles, avoids solid particle to block silk screen.
Grid packing thickness is 100-200mm, and wire packing thickness is 100-150mm, can obtain best foam removal effect.
Have employed technique scheme, the invention has the beneficial effects as follows:
Double-deck filler is arranged, and the gas containing liquid foam and solid particle flows from bottom to top, successively by grid packing and wire packing, carries out two-stage foam removal, and foam removal effect is better, also avoid solid particle blocking silk screen simultaneously.Bolt connects effectively to be fixed filler, and convenient disassembly is simple to operate.
Therefore, the present invention, compared with existing demister, has outstanding advantage and is: (1) upper strata wire packing lower floor grid packing foam removal effect is strong, and resistance performance is good; (2) change silk screen mounting or dismounting easily, few when accounting for, efficiency is high; (3) good, the stable operation of adjusting function, structure is simple, easily manufactured.
The novel wire mesh demister of one provided by the invention, structurally achieves adjustable, and mounting or dismounting are convenient, and efficiency is high, and for practical application provides great convenience, and foam removal is effective, and silk screen is not easy to block, and can be widely used in field of petrochemical industry.
