Supporting grid

The supporting grid limit structure also ensures reasonable gas-liquid distribution and contact of the limit device, avoiding wall flow and bias phenomena that are prone to occur with traditional bulk packing materials, and improving mass transfer efficiency.

1、 Product Performance Characteristics Description:

　　Supporting grid filling limit structure and layer limit deviceIncluding plastic grid packing and metal grid packing, it is a type of regular packing. Its design concept and innovative structure, analyzed from the perspective of mass transfer mechanism, show that the gas-liquid distribution and contact of the packing are reasonable, avoiding the wall flow and bias phenomenon that traditional bulk packing is prone to, improving mass transfer efficiency, reducing system resistance, increasing production capacity, reducing compressor power consumption, playing an energy-saving and emission reducing role, and reducing the discharge of gasification wastewater.

　　Supporting grid filling limit structure and layer limit deviceIt can not only cool down, but also wash and remove dust, and can wash away some tar, improve the operation rate of the compressor and reduce the load of electrostatic tar removal. Due to the inferior quality of Yangquan coal being burned, its thermal stability is poor. Every day, 17 tons of dust (with a dust content of 15% in the gas) are cleaned in the dust collector. The centralized washing tower is not blocked, and the resistance of a single tower is less than 0.5KPa. When the tower is opened and observed, the grid packing is very clean, without any coal ash or tar.

Installation method of packing support: Before installing the packing support grid and pressure frame, assemble the packing support grid and pressure frame separately outside the tower to confirm that there is no problem with the number of blocks; Then lift the packing support grid piece by piece into the tower for installation, and place the blocks of packing support grid in an orderly manner on the support ring and support beam; After the packing support grid is laid, the packing is orderly lifted into the tower and placed on top of the grid. After the packing is installed, the upper layer of packing should be leveled, and then the packing frame should be lifted into the tower in an orderly manner and laid on top of the packing. After the entire layer of packing is completed and the packing frame is laid, the blocks should be connected by screws to form a whole for fixing.
