Problems solved by technology

At this time, the pipeline will be blocked, and the air intake needs to be closed manually, and the air supply can only be continued after returning to normal temperature after deicing, which will affect the stability of production
At the same time, the excess SO2 in the existing technology permeates into the air of the workshop through the gap of the transition roller table, which is harmful to the human body.

Embodiment 1

[0031] Such as figure 1 As shown, the present invention provides on-line float coating glass transition roller table SO Protective gas system, described protective gas system includes SO Gas supply system and air seal gas supply system; Wherein,

[0032] The SO2 gas supply system includes SO2 gas source, buffer tank, SO2 main pipeline rotameter, connecting pipelines and a number of manual acid-resistant stainless steel flange cut-off regulating valves, and the SO2 gas source passes through the buffer tank into the SO2 main pipeline rotor flow rate After metering, it is connected to the gas seal gas supply system pipeline through the connecting pipeline to merge with the gas seal gas, and the flow ratio of SO2 / N2 between the two is between 1 / 1-1 / 4.

[0033] The gas sealing gas supply system includes a gas source, a gas sealing gas rotameter, a rotameter required for production, connecting pipelines and a number of manual acid-resistant stainless steel flange cut-off regulating ...

Embodiment 2

[0040] On the basis of Example 1, in order to control the flow rate, achieve less tempered iridescence, improve the surface strength of the glass, reduce the scratches on the lower layer of the glass, and delay the mold of the glass. As a preference, the SO2 trachea 7 Located at 30cm-60cm downstream of the air-sealing pipe 8 process, the SO2 air pipe 7 and air-sealing pipe 8 are arranged at 5-9cm below the glass plate surface, and the air pipe is provided with air holes 10, the diameter of which is 2-4mm. The spacing is 1-2cm, and the opening length is 3-5m. Adopting the structure of the jet tube mentioned above can also greatly reduce the impact on the coating quality. The jet tube is made of acid-resistant and high-temperature-resistant materials (below 700 degrees Celsius), which can effectively reduce the corrosion of the jet tube by SO2 gas.

Embodiment 3

[0042] As an improved form of the above-mentioned several embodiments, a SO2 gas collection device (not shown in the figure) is also provided at the position facing the SO2 gas pipe under the roller table, and the SO2 gas collection device passes through the pipeline and the suction The device is connected and passed into the lye for neutralization treatment.

[0043] It can effectively remove SO2 gas diffused in the air, and treat it with lye to reduce the pollution caused by direct emission of SO2 gas.

Abstract

The invention provides an SO2 protective gas system with a transitional roll platform in online floating-process film coating of glass and an operation method. The protective gas system comprises an SO2 gas supplying system, a N2 auxiliary-gas supplying system and a gas-sealing gas supplying system. The operation method is characterized in that two gas seals are arranged at the positions of a transitional roll platform close to a tin groove and an annealing kiln, an SO2 gas pipe is positioned between the two gas seals, gas sealing is carried on the transitional roll platform and the tin grooveby a front-end gas sealing pipe, and gas sealing is carried out on the joint positions of the transitional roll platform and the annealing kiln by a tail-end ; meanwhile, the lower sides of a first roller and a final roller of the transitional roll platform are respectively provided with a gas seal. The protective gas system provided by the invention has the beneficial effects that the productionneeds are met to a greatest extent, the consumption of SO2 gas is greatly reduced, the operation is convenient, the operation risk of workers is reduced, the adjustment time is saved, the pollution and the hazard to the environment are reduced, and meanwhile, the influence of SO2 on the tin groove, the annealing kiln and the film coating is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of float glass production, in particular to an SO2 protective gas system and operation method for an online float coated glass transition roll table. Background technique [0002] In the production process of float glass, the section of thermal equipment from the outer wall of the tail end wall of the tin bath to the outer wall of the annealing kiln is called a transition roller table. On-line float coating is to add a coating reactor in the tin bath and annealing kiln of the ordinary float glass production line (or separately set in the tin bath or annealing kiln), and directly coat the float glass on the surface of high-temperature glass by CVD online chemical vapor deposition method. Coating production process. [0003] The SO2 gas is connected to a hole pipe, and enters the transition roller table through the reserved hole between the rollers on the top of the transition roller table. SO2 gas can reduc...
