Anti-slurry-pollution method for spray tower observation window
ActiveCN107327259ADoes not affect airtightnessNo need to change the structureDoor/window applicationsWindow cleanersAgricultural engineeringSlide plate
The invention discloses an anti-slurry-pollution method for a spray tower observation window. The anti-slurry-pollution method comprises the following steps that an inner sliding plate and an outer sliding plate are installed, the left sides and the right sides of the inner sliding plate and the outer sliding plate are provided with limiting devices, an inner sliding plate cleaning part is installed, a spray preparing phase is observed, spray is observed, and the upper half part of an inner transparent plate is cleaned. According to the anti-slurry-pollution method for the spray tower observation window, under the premise that an existing spray tower body structure is not changed and the gas-tightness of a spray tower is not influenced, a spray rod, a nozzle angle and the spray effect are observed conveniently through an existing observation window, the observation effect of the observation window is clear, and the observation window is not prone to being polluted.
