The Study Of Pre-evaporation Incineration Technology For Gas Phenol Water

The massive virulent gas phenol water is produced in the gas stations. Pre-evaporation incineration technology is introduced with the characteristic of fixed bed gas stations.The findings indicates: Pre-evaporation incineration technology evaporates phenol water with sensible heat of the lower-stage gas and the phenol steam was reinjected in fire layer, which not only achieves the goal of controlling phenol pollution, but also fully uses the sensible heat in the lower-stage gas without increasing equipment. It is obvious that the evaporative characteristics of the gas phenol water are related to the temperature, tar(which is main point to the stability of the evaporation), salinity, density and ash of the gas phenol water from the analysis of phenol water evaporation test; The equipment has been chosen according to the nature of the high temperature gas and the evaporation characteristics of the gas phenol water—once-through coiled tube evaporator. The decomposition temperature of phenol material is 850~900℃, which may be decomposed completely when the temperature of fire layer is controlled about 1250℃in gas stove, and may be respond fully through 300 mm of burning shell; When the once-through coiled tube evaporator was researched through the theory and experiment, the commercial test has been carried out in some factories.The equipment moves one cyclical for 282 day safely and stably. This phenol water evaporator is of high efficiency energy saving. The blockage phenomenon has not been discovered in the pipeline and equipment. The pre-evaporation incineration technology and the structure of the phenol water evaporator have been proved completely feasible.
