Problems solved by technology

[0003] Chemical vapor deposition (CVD) technology is a modification technology that has been applied to inorganic porous materials since the late 1980s. It can be applied to the modification of nano-scale porous glass substrates. The appendages produced by this process are often discarded, resulting in material waste and not conducive to environmental protection

Embodiment 1

[0024] This embodiment discloses a method for recycling the appendages produced by the glass CVD coating process. Specifically, the method includes the following steps:

[0025] S1: Dry the appendages produced by the glass CVD coating process in a drier to obtain dry powder;

[0026] S2: adding the dry powder obtained in S1 to a vibration filter for vibration separation to obtain a separated mixture;

[0027] S3: adding the separation mixture obtained in S2 into an air suspension separator for fine separation treatment to obtain nano-sized tin dioxide and micron-sized sodium bicarbonate respectively.

[0028] The above-mentioned drying time is 30 minutes.

[0029] The above-mentioned drying temperature is 50°C.

[0030] In S2, the time of shock separation was 30 minutes.

[0031] In S2, the vibration filter had a particle size pass size of 37 microns.

[0032] In S3, the fine processing time is 15 minutes.

[0033] The tin dioxide obtained by separation is detected by X-r...

Embodiment 2

[0036] This embodiment discloses a method for recovering the appendages produced by the glass CVD coating process. The only difference from Embodiment 1 is that the drying time in the drier is 40 minutes.

Embodiment 3

[0038] This embodiment discloses a method for recovering the appendages produced by the glass CVD coating process. The only difference from Embodiment 1 is that the vibration separation time in the vibration filter is 35 minutes.

Abstract

The invention relates to the field of chemistry, in particular to a method of recovering a byproduct generated by a glass CVD (chemical vapor deposition) filming technology and an application of the method. The method comprises the following steps of: S1: drying the byproduct generated by the glass CVD technology in a drier to form dry powder, S2: adding the dry powder obtained in S1 into a vibration sizer for vibration separation to form a separation mixture, and S3: adding the separation mixture obtained in S2 into an air suspension separator for refined separation treatment to form nanoscale tin dioxide and micron-sized sodium bicarbonate. The method is simple in step and low in cost; nanoscale tin dioxide recovered by the method can serve as a raw material of automobile tail gas purifying agent; materials can be recycled; the cost of the raw material of the automobile tail gas purifying agent is lowered; the method can be used for the field of automobile environmental protection and solves the pollution emission problem of a glass enterprise at the same time.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to a method for recovering the appendages produced by the glass CVD coating process and its application. Background technique [0002] In order to protect the environment, people usually use catalysts containing precious metals such as platinum, rhodium, and palladium to absorb and reduce polluting gases emitted in the air. With the promotion and application of new clean energy, such as natural gas, the exhaust gas index has also been reduced, and new and cheap catalysts have been widely used. [0003] Chemical vapor deposition (CVD) technology is a modification technology that has been applied to inorganic porous materials since the late 1980s. It can be applied to the modification of nano-scale porous glass substrates. The appendages produced by this process are often discarded, resulting in material Waste and not conducive to environmental protection. [0004] Studies have shown that t...
