Abstract
The industrial filler of polyvinyl chloride is used to replace ceramic, metal and plastic filler in filler tower in alkali and alkali chloride producing industry. It is produced through direct inject moulding with polyvinyl chloride. It has the features of high alkali resistance, strong ageing resistance, high strength, high rate of mass transfer, small bulk weight, low cost and long service life.
Description
The present invention relates to a kind of industrial filler, particularly a kind of industrial filler of polyvinyl chloride that is applied in caustic soda and the chlor-alkali industry packed tower.
At present, be used in the industrial fillers such as garland, Pall ring of chlor-alkali and caustic soda industry both at home and abroad, its material mostly is conventional pottery, metal and conventional plastics, but ceramic packing is frangible, and the pressure drop resistance is big, and hydrodynamic performance is poor, stop up easily, mass-transfer efficiency is not high, and service work labour intensity is big, changes frequent, cause investment and cost to increase, and metal packing is poor to the corrosion resistance of chlor-alkali, and weight accumulation is big, the cost of investment height; Conventional plastic filler is in the alkali industry, and not corrosion-resistant, ageing resistace is poor.
It is strong that the present invention aims to provide a kind of anti-genus erosion property, ageing resistace that is used for making the alkali industry, can be broken, and the mass-transfer efficiency height, weight accumulation is little, the industrial filler of polyvinyl chloride that cost is low.
The present invention only needs chliorinated polyvinyl chloride is made the industrial filler in the alkali-making industry packed tower of being used for of all size and model through injection moulding.
The present invention has in light weight, anti-aging, be able to bear strong corrosion, be difficult for advantages such as fragmentation, in the dry chlorine of chlor-alkali industry, chlorine and hydrogen processing section, can replace ceramic packing, conventional plastic filler and stainless steel helices in the devices such as chlorine gas drying tower, absorption tower, dechlorinator, in addition, the present invention also has reusable, maintenance and cleaning easily, the advantage of long service life.
Provide several embodiments of the present invention below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the embodiment of the invention 1.
Fig. 2 is the structural representation of the embodiment of the invention 2.
Fig. 3 is the structural representation of the embodiment of the invention 3.
Above-mentioned three embodiment adopt chliorinated polyvinyl chloride injection molded, and wherein embodiment 1 is a garland, and embodiment 2 is a Pall ring, and embodiment 3 is a cascade ring.
Claims (4)
1, a kind of industrial filler of polyvinyl chloride is characterized in that adopting chliorinated polyvinyl chloride injection molded.
2, a kind of industrial filler of polyvinyl chloride according to claim 1 is characterized in that this industrial filler is a garland.
3, a kind of industrial filler of polyvinyl chloride according to claim 1 is characterized in that this industrial filler is a Pall ring.
