Description

Tail-blockage-preventing water bottle of solar diffusion furnace

Technical Field

The utility model relates to a solar cell production field.

Background

In the production process of solar cells, diffusion is an important process, and the quality of the diffused silicon wafer affects the main performance of the cell. At present, a machine table is a negative pressure diffusion machine table, the pressure in a furnace is an important control factor for carrying out the process, and the square resistance can be directly influenced by larger or smaller pressure. The pressure is monitored and achieved by a pump at the location of the exhaust treatment. When the pump is used for pumping negative pressure, the smooth condition of the tail gas pipe can influence the pressure pumping effect, the pressure cannot be pumped down after the pipeline is blocked, the pressure cannot reach a set value, and rework can be caused. The main reason for tail exhaust blockage is that waste gas generated in the process cannot be well evacuated, and is condensed at a tail exhaust pipeline to cause pipeline blockage. The main substance generated by the reaction is metaphosphoric acid, which can be diluted by water vapor, and the diluted metaphosphoric acid is not easy to condense at the tail discharge position. The machine table is provided with a water bottle for improvement, waste gas generated by reaction is diluted by water vapor, and tail blockage is easy to occur in actual production. In order to meet the process requirements, the tail gas is required to be frequently maintained, and frequent maintenance of the machine table causes frequent shutdown and seriously affects the start-up rate. The main devices of the tail gas treatment part are made of quartz, and after maintenance frequency is increased, maintenance actions are increased, so that the damage probability of quartz parts is increased.
