Abstract
The invention provides a ceramic packing processing method. The method includes the steps of blending, smashing, mixing, ball-milling, water adding, mud refining, forming, low-temperature drying, kiln feeding, firing and the like. Due to the fact that in the processing process of packing, smashing is conducted firstly and then mixing and ball-milling are conducted, the smashing efficiency is improved, and raw materials can meet the requirement for the particle size quickly; due to the fact that the surface of the packing is coated with a 1Cr13 coating, the corrosion resistance and strength of the packing are further improved.
Description
Technical field
The present invention relates to a kind of working method of ceramic packing, belong to petrochemical complex mass transfer separation equipment technical field.
Background technology
In chemical engineering, filler refers to the inert solid material be loaded in packed tower, such as Pall ring and Raschig ring etc., and its effect is the contact surface increasing solution-air, makes its mutual intense mixing.Dumped packing is the granule one by one with certain geometrical shape and size, is generally deposited in a random way in tower, is also called dumped packing or granular filler.Dumped packing is different according to constructional feature, can be divided into again ring packing, saddle packing, ring saddle packing and Ball-type packing etc.
Current packing tower has been widely used in the unit operation such as rectifying, absorption, extraction of the industrial circles such as chemical industry, oil, medicine, environmental protection, it is a kind of traditional fluid contacting equipment, contact to realize mass transfer or chemical reaction for two between gas-liquid, liquid-liquid, one deck or multiple filling layers are generally equipped with in packing tower inside, the quality of packing tower mass-transfer performance depends primarily on the performance of filler used, and filler divides by its structure can be divided into structured packing and granular filler.
Filler is all in hot environment in use, and the material component that mass transfer is separated is complicated, often in acid or alkaline, makes filler be very easy to be corroded in the Working environment of high temperature with aging.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes a kind ofly can obtain working method that is corrosion-resistant, high temperature resistant and aging-resistant ceramic packing.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of working method of ceramic packing, comprises the following steps:
(1) prepare burden: in the raw material of described ceramic packing, the parts by weight of each component are: nano-calcium carbonate 4-5 part, montmorillonite 7-8 part, sepiolite 5-6 part, kaolin 20-25 part, AlN powder 4-5 part, wollastonite 6-8 part, diopside 6-8 part, anti-aging agent RD 5-6 part and clay 38-42 part;
(2) pulverize: use pulverizer to be pulverized respectively by above-mentioned raw material, after pulverizing, the particle diameter of raw material is between 9mm-12mm;
(3) mixing and ball milling: raw material is put into mixing and ball milling instrument by described parts by weight and carries out mixing and ball milling, after mixing and ball milling, the particle diameter of raw material is between 8000-12500 order;
(4) add water: add water the raw material after mixing and ball milling mixing, and after adding water, moisture content of raw material is 26%-28%;
(5) pugging: the raw material after adding water is put into vacuum deairing machine and carries out pugging, vacuum tightness is 0.07-0.09Mpa;
(6) shaping: to use mould to be pressed into granular filler shape;
(7) cryodrying: the granular filler feeding low-temperature drier after shaping is carried out cryodrying, and control drying temperature is 70-80 DEG C, is dried to shaping filler moisture content and is less than 3%;
(8) kiln is entered: the filler after shaping is sent into tunnel furnace;
(9) fire: electric field-activate hot pressing aid burning stove sinters;
(10) coating: adopt Ultrasonic Arc Sprayed 1Cr13 coating, 1Cr13 coating spraying thickness is 50 ± 50 μm.。
The present invention adopts the beneficial effect of technique scheme to be: (1), in the course of processing of filler, owing to first pulverizing rear remix ball milling, improves crush efficiency, makes raw material meet the requirements of size fast; (2) use vacuum deairing machine, feed components is distributed and is tending towards even, structure comparison is fine and close, and plasticity-and the dry tenacity of pug all increase; (3) make shaping filler moisture content be less than 3% by cryodrying, significantly shortened and energy consumption reduction the firing time; (4) use electric field-activate hot pressing aid burning stove sintering, power consumption is inefficient high, obtained that filling intensity is high; (5) due to filling surface spraying 1Cr13 coating, the erosion resistance of filler and intensity are improved further.
