Two-stage seal valve
  • Features


The sealed bin type two-stage seal valve has become one of the indispensable equipment in the production of environmentally friendly lime kiln. 必须停风出灰 不但每天减少三分之一的产量,而且使炉内煅烧不稳定,影响产品质量。 In the past, when the ash discharge equipment was in operation, because the pressure in the furnace could not be kept constant, the ash had to be stopped to produce ash , which not only reduced the output by one third every day, but also made the calcination in the furnace unstable and affected the product quality. ,出灰时正常鼓风,能够完全避免炉气的外泄,真正实现 不停风连续生产 The use of a sealed bin type two-stage sealing valve can achieve normal ash discharge under non-stop air conditions , and normal blast during ash discharge, which can completely avoid the leakage of furnace gas and truly realize continuous production without stopping air .

The working process is: when the ash is discharged, the upper valve is controlled by the computer to open, the finished ash enters the warehouse, after reaching a certain amount, the upper valve is closed, the lower valve is opened, and the finished ash is discharged from the furnace body. Instead, it acts as a seal to ensure that the pressure in the furnace is leaked during ash discharge, thereby achieving a stable and constant supply of air in the shaft furnace and a reasonable distribution of airflow in the furnace. The coal combustion is continuous and stable, which effectively improves the calcination quality and improves Lime production has also greatly improved the working environment. The sealed bin type two-stage sealing valve has been widely used in the production process of kiln, and has achieved objective economic benefits (energy saving) and social benefits (environmental protection), and its significant increase in production and energy has been recognized by the majority of manufacturers.
