Embodiment Construction

[0016] A method for enhancing water evaporation and chromatographic separation with a porous material with capillary action. The porous material with capillary action is placed in salt pans or brackish water pools or industrial wastewater or sewage pools containing non-volatile pollutants , the porous material with capillary action can be infiltrated by seawater or brackish water or industrial wastewater or sewage containing non-volatile pollutants.

[0017] The porous material with capillary action can be selected from natural fibers or cloth woven from natural fibers, synthetic fibers or cloth woven from synthetic fibers, metal fibers or cloth woven from metal fibers, or carbon fiber cloth.

[0018] Natural or synthetic fibers or metal fibers and cloth woven respectively from them or carbon fiber cloth of a thickness of 0.01 mm, or 100 mm, or 0.1 mm, or 1 mm, or 10 mm, or 30 mm, or 50 mm, or 70 mm mm, or 90 mm.

[0019] The porous material with capillary action can be suspe...

Abstract

The process of utilizing capillary porous material in reinforcing water evaporation and separation is to set one or several kinds of capillary porous material, such as natural fiber, synthetic fiber, metal fiber, carbon fiber cloth, porous ceramic plate, diatomite, etc., inside brine pan, bittern pond, industrial waste water pond with non-volatile pollutant or sewage pond to increase water evaporating area, reinforce water evaporation, raise salt yield or waste water treating amount, separate salt and non-volatile pollutant, save energy and raise separation efficiency.

Description

technical field [0001] The present invention relates to a method for intensifying water evaporation, in particular to a method for intensifying the evaporation and chromatography of salt pan seawater or brackish water or industrial waste water or sewage containing pollutants as non-volatile substances by using a porous material with capillary action method of separation. Background technique [0002] In the process of drying salt in traditional salt fields, the evaporation area of ​​seawater is limited to the surface of seawater. The contact area between air and seawater is small, which is not conducive to water evaporation, and the salt production per unit area of ​​salt fields is low. In order to strengthen the evaporation of seawater, people try to increase the evaporation area. In the patent CN1077935A, a method of sprinkling salt water at a certain height, or spraying at a certain height under a certain pressure, three-dimensionally expands the contact area between the...
