A high-efficiency preparation method of airgel and its application. The liquid preparation and hydrolysis in the early stage of the method are all completed in the reactor, using alkoxysilane as raw material, hydrolyzing it to form a sol, and entering into the intelligent production of airgel in the later stage After the system is integrated, it is intelligently controlled by the computer to realize the intelligent control of various electrical signals, and then control the operation of the transmission device, control the start and stop of the glue spray gun and the temperature and humidity in the liquid spray cabin, and control the heating and heat preservation cover I and the heating and heat preservation The temperature and holding time in the cover II; through intelligent glue spraying, the mold and the airgel products inside are transmitted in the airgel intelligent production integrated system to realize the continuous production of wet gel curing, aging and modification ; The product is obtained after drying, and the alkoxy alcohol produced by hydrolysis is recovered and recycled for the preparation of alkoxysilane. The invention reduces the transferred materials in the gel preparation process, simplifies the process, and reduces the production cost; at the same time, it also reduces the escape of volatile materials and is environmentally friendly.

The invention discloses a treatment method for CTC rectifying still residues and belongs to the technical field of treatment of solid waste in chemical industry production processes. According to the method, a solvent is added into the rectifying still residues for an impurity removing technique at first; and then solid alkali is added into a mixed liquid subjected to impurity removing in batches, a temperature increasing refluxing reaction is conducted, high-content pyridine chlorides are converted into carbon, hydrogen, oxygen and nitrogen compounds, and incineration treatment is facilitated. The economic pressure of enterprises for treating the still residues is relieved, and the environment is protected.

The invention discloses a lining barrel for an antistatic chemical raw material barrel and a process thereof. The lining barrel comprises a raw material barrel, a barrel handle, a barrel lid and a lining barrel body, wherein two handle holes are formed in the side face of the raw material barrel, fixing lugs are arranged at the outer ends of the holes, and through holes are formed in the fixing lugs. Rotating plates are arranged in the handle holes, and the barrel handle is arranged at one ends of the rotating plates. The barrel handle penetrates through the through holes, and the barrel handle is provided with a handle protecting shell in a penetrating mode. The handle protecting shell is provided with a handle ring in a penetrating mode. The lining barrel has an antistatic function, andprevents chemical raw materials in the barrel from generating static electricity during transportation to cause a safety accident; the lining barrel has a light weight, few chemical raw materials arebonded to the barrel wall, the cost of solid waste treatment is low, and a good environmental protection effect is achieved; and the lining barrel has high corrosion resistance, the outer lining ironbarrel can be recycled, and the usage cost of the chemical raw materials is greatly reduced.
