Cleaning etc., such method for cleaning can make colloid be homogenously mixed together with water, can not separate, in post-processing, also
It needs waste liquid tune pH value and carries out sedimentation separation, and have that colloid is molten can not to be thoroughly kept completely separate in water always, in this way
A large amount of waste water will be generated to cause stress for subsequent processing, and such manner of cleaning up colloid stronger for adhesiveness
Material, depending cleaning alone can not completely remove, and use there are also inventor and install cleaning ring in reaction kettle body, but cleaning ring
Always there is dead end of cleanning, can not clear up thoroughly, the later period is cleaned there is still a need for clear water.
Summary of the invention
The technical problems to be solved by the present invention are: the method for cleaning cleaning colloid residue of existing reaction kettle is not thorough
Bottom, and a large amount of waste water can be generated, environmental protection is caused stress.
The present invention provides a kind of clean methods of the reaction kettle colloid reaction residue to solve the above problems.
The present invention is achieved through the following technical solutions:
A kind of clean method of reaction kettle colloid reaction residue, includes the following steps:
Step 1: it opens heating element and is heated；
Step 2: moving up and down inner shaft, adjusts the angle of agitating paddle, and the inner wall of the end and reaction kettle body that make agitating paddle connects
Touching；
Step 3: opening the motor of mechanical oscillation stick, drives mechanical vibrating head vibration, and dry colloid is peeled off from inner wall
It falls into reaction kettle body bottom and forms colloid residue；
Step 4: being added a small amount of water and colloid mixes outside merga pass discharge port discharge reaction kettle body；
Step 5: colloid residue and water are separated by solid-liquid separation.
The present invention utilizes colloid drying and dehydrating, and hardened lump is agglomerated between molecule, and viscosity sharply declines to nothing
Method is adhered on the inner wall of reaction kettle body, realizes that Automatic-falling passes through mechanical oscillation for the drying colloid that can not be completely fallen off
The effect of vibration of stick drives its peeling, then leads to too small amount of water for colloid residue band and separates out reaction kettle body, is finally consolidated again
Liquid separation, this method Water usage is few, and hardened colloid residue will not be redissolved in water, and water is intended only as colloid residue row
Medium outside reaction kettle body out, can be with direct emission after separation, environmental protection, and cleaning is thorough.
In order to guarantee that colloid can be by abundant dried cake, preferably a kind of cleaning of reaction kettle colloid reaction residue of the present invention
Method, in the step 1, the temperature of heating is 80-150 DEG C, and the time of heating is 4-12 hour, by the operation so that suddenly
The water content of nurse stone colloid is reduced to 10% by 70% or so, and according to drying principles, the water of colloid surface is first evaporated and dried, residual
The a small amount of water stayed can be locked in the inside of colloid, at this point, the volume of Boehmite Sol can substantially be shunk, agglomerate and alice occur,
It can fall off from reaction kettle inner wall to most of, leave behind small part and be slightly attached on inner wall.

Need a small amount of water flowing that colloid residue is driven not precipitate, it is different from traditional colloid of being cleared up under water environment, in order to
Inner wall residue is carried out to wash away removal, needs to fill almost entire reaction kettle body inner wall, and wash away and fall to by stirring
Colloid in water will disperse in water, since the partial size very little of colloid is nanoscale, can generate so largely with dispersion agent
The waste water of body, wastewater treatment capacity is big, and needs to adjust pH value and come so that the layering of colloid residue wastewater sedimentation, processing cost
Height, it is also different for the existing mode struck off from the top down only by scraper plate, when striking off, struck off due to existing always
Less than dead angle, such as the intersection of the side wall of reaction kettle body and bottom, and scrapings deposit to the colloid of bottom can not
It is rejected to outside reaction kettle body, it is still desirable to which water carries out mixing and takes out of, but equally exists colloid in normal state and will disperse in water
It is middle to form diluted colloidal solution waste water, need to adjust pH value to be layered, processing is cumbersome, at high cost and the high pH value of generation useless
Water not environmentally present invention take advantage of that forming lump after colloid is dry, and is no longer disperse in water, without adjusting pH value, the PH of water
Value still keeps neutral, can preferably realize separation of solid and liquid without a large amount of water.
The step of preferably a kind of clean method of reaction kettle colloid reaction residue of the present invention, the separation of solid and liquid are as follows: will
