Problems solved by technology

The first example of the prior art introduces that the direction of material transmission in the drying kiln is opposite to the direction of hot air transmission. It is an activated clay drying system that saves energy, reduces dust and has higher evaporation efficiency. It does not introduce the entire activated clay preparation system.

Embodiment Construction

[0023] The device will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] The invention is attached figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , attached Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, a method for using a special preparation device for activated clay is characterized in that: step 1, using boiler tail gas as the transport of circulating fluidized bed coal-fired boiler fly ash, activation medium and heat energy required for activation and sulfuric acid as an activator The activation process is completed in the activation tower component 1. The boiler tail gas is the boiler flue gas taken from the flue connecting the boiler heat exchange system and the dry dust collector. The temperature is about 160-190 ° C, SO 2 The concentration is about 1000-2500mg / m 3 , the fly ash of the circulating fluidized bed coal-fired boiler enters the activation tower ...

Abstract

The invention relates to the technical fields of environmental protection and circular economy, and concretely relates to a use method of a special production device used for floridin. The method is characterized in that boiler tail gas used as a circulating fluidized bed coal-fired boiler fly ash conveying and activating medium and providing heat energy needed by activation and sulfuric acid used as an activator complete an activation process in an activation tower assembly, circulating fluidized bed coal-fired boiler fly ash is separated from acid fog tail gas in a gas box pulse bag type trap, an elevator I conveys the circulating fluidized bed coal-fired boiler fly ash to a rotary rinsing cylinder in order to make the fly ash be rinsed, the rinsed fly ash is dehydrated by a centrifuge dehydrator, and the dehydrated circulating fluidized bed coal-fired boiler fly ash which enters a secondary activating and drying rotary furnace through an elevator II undergoes secondary activation and drying under the action of the boiler tail gas used as the activating medium and providing heat energy. The device has the advantages of high automation degree, realization of integral intelligent enforcement of various complex process flows, and simplicity in operation and use.

Description

technical field [0001] The invention relates to the technical fields of environmental protection and circular economy, in particular to a method for using a special preparation device for activated clay. Background technique [0002] Activated clay is widely used in chemical industry as catalyst, filler, desiccant, adsorbent, flocculant for wastewater treatment, etc. For example, refining of animal and vegetable oils in the edible oil manufacturing industry; in the petroleum industry, it is used for the refining, decolorization and purification of minerals such as petroleum, oil paraffin, wax oil, kerosene, and petroleum cracking; in the food industry, it is used as a clarifying agent for wine and juice, Beer stabilization treatment, saccharification treatment, sugar juice purification, etc.; in medical and health, it can be made into anti-chemical drug addicts and antidotes. With the development of society and science, the application of activated clay is more and more ext...
