Problems solved by technology

[0003] From the above working principle, it can be seen that the fillers play a very critical role in the heat exchange effect of cooling towers; at present, plastic S-wave water fillers are mostly used in cooling towers, but this kind of fillers, since the material is plastic , easy to age and deteriorate, resulting in short service life, poor stability, low corrosion resistance, easy to form secondary pollution, and poor thermal conductivity; secondly, the plastic S-wave water filler has a multi-layered S-shaped plastic plate due to its structure The block shape formed by overlapping each other leads to high resistance and low efficiency in the process of heat exchange with the medium, and the plastic plate filler with this structure has a relatively small specific surface area, resulting in a small contact area of ​​the exchange medium, which is not conducive to mass transfer

Abstract

The invention discloses pored flower-shaped multi-rib ceramic packing and a preparation method thereof. The pored flower-shaped multi-rib ceramic packing is characterized in that the pored flower-shaped multi-rib ceramic packing comprises a ceramic packing body; the ceramic packing body is formed by mutually splicing seven hollow column bodies of which the cross sections are orthohexagonal; the seven hollow column bodies comprise the upper row of hollow column bodies, the middle row of hollow column bodies and the lower row of hollow column bodies, that is two hollow column bodies are located in each of the upper row and the lower row and three hollow column bodies are located in the middle row; and parting plates which divide the cross sections of the hollow column bodies into three equal parts correspondingly and extend in the length directions of the hollow column bodies are arranged in the hollow column bodies. The pored flower-shaped multi-rib ceramic packing has the advantages that the pored flower-shaped multi-rib ceramic packing is long in service life, good in stability and heat-conducting property, large in specific surface area, and easy in mass transfer, is corrosion-resistant, is not aged easily, and does not create secondary pollution easily.

Description

technical field [0001] The invention relates to the field of chemical equipment packing, in particular to a flower-shaped multi-reinforced ceramic packing with holes and a preparation method thereof. Background technique [0002] The natural ventilation cooling tower is a cooling tower that is ventilated by the air density difference inside and outside the tower or the air convection formed by natural wind. The throat presses the circulating water into the water spreading system of the cooling tower, and spreads the water evenly on the filler through the small holes on the water spreading pipe; the dry air with low enthalpy enters the tower from the bottom air inlet net under the action of the fan Inside, when the hot water flows through the surface of the filler, a water film is formed to exchange heat with the air. The hot air with high humidity and high enthalpy is drawn from the top, and the cooling water drops into the bottom basin, and flows into the main engine throug...
