Problems solved by technology

[0005] (1) Due to the small thermal conductivity of active coke and poor heat transfer performance, it takes enough time for heat transfer to reach the regeneration temperature of active coke, and the active coke is in a relatively static state in the regeneration reactor, which causes this type of regeneration reactor The processing capacity is relatively small. For enterprises adopting this kind of flue gas purification technology on a large scale, it is necessary to build multiple sets of regeneration reactors to match the scale of active coke regeneration, so that the energy consumption and land occupation of this type of equipment have great disadvantages.

Embodiment 1

[0038] Example 1. Regeneration device for combined desulfurization, denitrification and demercuration active coke

[0039] Such as figure 1 As shown in Figure 2, the regeneration device for combined desulfurization, denitrification and demercuration active coke provided by the present invention includes a rotary kiln 2 and a material cooler 3; The feed port end of the converter 2 is higher than its discharge port end, which helps active coke move slowly from its feed port end to the discharge port end along with the rotation of the rotary kiln; the feed port end of the rotary furnace 2 There is a feed bin 1 on the top, and the feed bin 1 is connected with the ring cavity of the rotary furnace 2, and the active coke to be regenerated enters the ring cavity of the rotary furnace 2 from the feed bin for regeneration; the material cooler 3 is connected with the rotary furnace The ring cavity of 2 is connected, and the connection is located near the discharge port of rotary furnac...

Embodiment 2

[0040] Embodiment 2, regeneration of active coke

[0041] Such as Figure 2aAs shown, using hot flue gas or hot waste gas as the heating medium, the regeneration device provided above is used to regenerate the active coke. The specific process is: in the flue gas purification reactor 4, the active coke desulfurizes and purifies the flue gas; The bottom of the flue gas purification reactor 4 is discharged into the feed bin 1, and then into the ring chamber of the rotary furnace 2; at the same time, under the action of the induced draft fan 6, the heating medium (hot flue gas or hot waste gas, the temperature is 450°C) from the outlet end of the rotary furnace 2 into the furnace body of the rotary furnace 2; the active coke in the rotary furnace 2 slowly moves to the outlet end with the rotation of the rotary furnace 2, and then in the rotary furnace 2 , the active coke and the heating medium move towards each other and exchange heat, such as image 3 As shown, activated coke ...

Abstract

The invention discloses a regeneration method of desulphurization, denitration and demercuration combined activated coke and a special-purpose device thereof. The regeneration device comprises a tilting furnace and a material cooler. The tilting furnace is arranged aslant relative to the horizontal plane and a feed inlet of the tilting furnace is higher than a discharge port of the tilting furnace. The feed inlet of the tilting furnace is provided with a feed bin which communicates with a ring cavity of the tilting furnace. The material cooler communicates with the ring cavity of the tilting furnace. The juncture is near the discharge port of the tilting furnace. The invention provides the method for regenerating activated coke by the use of the above device. In comparison with processing capacity of an industrial vertical regeneration reactor, the processing capacity of the tilting furnace in the regeneration device provided by the invention is greatly raised. The device is especially suitable for an utility boiler or other large-scale boiler by large-scale adoption of a flue gas purification technology with activated coke.

Description

technical field [0001] The invention relates to a method for regenerating activated coke combined with desulfurization, denitrification and demercuration and a special device thereof. Background technique [0002] Activated coke flue gas purification technology is an advanced dry flue gas purification technology. This technology has high desulfurization, denitrification, and mercury removal efficiencies. Recycling and utilization of resources can alleviate the current shortage of sulfur resources in my country to a certain extent; the adsorbent used uses coal, which is relatively abundant in my country's reserves, as the main raw material, and the supply of raw materials is fully guaranteed. Therefore, this technology is an efficient and economical joint control technology for coal-fired flue gas pollutants that is suitable for my country's national conditions. [0003] Activated coke after flue gas purification has adsorbed a large amount of SO 2 (existing in the form of s...
