Embodiment Construction

[0018] The filtration process of the ceramic hot gas dust removal and acid removal method provided by the present invention is as follows: figure 1 shown, including the following steps:

[0019] 1) Dissolve ceramic fiber in water, add positive and negative ion binder, the weight ratio of positive ion binder and negative ion binder is 3:5. The positive ion is silicon oxide, and the negative ion is starch, so that the negative charge on the fiber forms a repulsive force to stretch, and at the same time, the positive ion silicon oxide adsorbs the negative ion, and evenly distributes it to form the strength of the initial drying embryo. Suitable for use at high temperature, it can run at 450 degrees Celsius for a long time and 1000 degrees Celsius for a short time. Reduce high temperature waste gas for environmental protection treatment, the cost and equipment investment are generated. For example, biomass boiler emissions can achieve high-temperature gas directly filtered to me...

Abstract

The invention provides a ceramic hot gas dust and acid removing method. A channel gap and a framework of a filter element are controlled so that gas can pass the channel gap but particle dust cannot pass the channel gap, and the particle dust can be adsorbed to the outer wall of the filter element. By means of timing frequency recoiling of the gas on the inner side of the filter element, the dust on the outer wall of the filter element disengages, it is guaranteed that the dust in exhaust gas can be filtered, collected and exhausted in an environment-friendly mode. Neutralizing and adsorbing medicament are sprayed to the exhaust gas, the acid gas is removed in a drying mode, and the particle pollution and acid pollution are efficiently eliminated.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a method for dedusting and removing acid from ceramic hot gas. Background technique [0002] At present, domestic waste gas treatment is generally adopted. Water spray absorbs part of the dust, cyclone dust removes most of the large particle dust, and electric ions are used to treat part of the dust. If it is necessary to remove the discharged acid gas, it is also necessary to use alkaline water spray to treat the acid gas, which will result in high investment in equipment and operating costs, waste of water resources, complicated treatment steps, and secondary pollution. And the cost of dealing with secondary pollution is very high. [0003] Due to the PM2.5 particles in the exhaust gas, it is difficult to effectively remove, such as dioxin, the existing conventional methods are difficult to deal with, and the efficiency is very low. The current treatment method is not suita...
