Problems solved by technology

At present, in this kind of process, the active coke used is all granular (spherical or cylindrical), and adopts a close-packed method. The active coke reaction bed cannot be stacked too high, so that it occupies a large area, and the close-packed air resistance is large. , the fan introduced to overcome the large wind resistance has a very high power consumption, which is not conducive to the promotion of this type of process

Embodiment 1

[0039] The following is attached Figure 1-2 An embodiment of the technical solution of the honeycomb activated coke for flue gas purification, which is the object of the present invention, will be described in detail.

[0040] Such as figure 1 As shown, the honeycomb activated coke for flue gas purification described in the technical solution of the present invention is a columnar body 1, such as figure 2 As shown, the cross-section of the columnar body 1 is square, and the interior is honeycomb-shaped. There are several flue gas channels 2 passing through the axial direction of the columnar body 1. The cross-sectional shape of the flue gas channel in this embodiment is square.

[0041] In practical application, the cross-section of the columnar body is rectangular, circular, regular hexagonal or other shapes. Preferably, the shapes and sizes of the several flue gas channels inside the columnar body are the same. The cross-sectional shape of the flue gas channel is pref...

Embodiment 2

[0045] Embodiment 2 is the first embodiment of the preparation method of honeycomb activated coke for flue gas purification according to the second object of the present invention.

[0046] In this embodiment, the production method of honeycomb activated coke for flue gas purification includes the following four steps:

[0047] Step (1): Batching and mixing: Based on the total mass of active coke powder and additives being 100%, the solid powder raw materials are configured according to the following mass fractions, active coke powder is 50-80%; additive powder is 20-50%. The solid powder raw material of the agent is mixed evenly until the powder material after mixing is uniform in color;

[0048]Step (2): Kneading: While constantly stirring the above powder materials, add water and monoethanolamine to knead the obtained mud materials so that the added liquid auxiliary materials and powder materials are fully contacted and mixed, and glass fibers are evenly added during the kn...

Embodiment 3

[0058] The third embodiment is the second embodiment of the preparation method of the honeycomb activated coke for flue gas purification according to the second objective of the present invention.

[0059] In this embodiment, the production method of honeycomb activated coke for flue gas purification includes the following four steps:

[0060] Step (1): Batching and mixing. Take 500g of active coke powder and 500g of pottery clay and fully mix until the color is uniform.

[0061] Step (2): Knead. Slowly add 80 ml of water to the above raw materials, and keep stirring and kneading for 30 minutes, slowly add 10 g of glass fiber, and continue kneading for 30 minutes to obtain the sludge to be extruded.

[0062] Step (3): extrusion molding. The sludge to be extruded is put into the extruder, and the honeycomb active coke wet body is obtained by forming through the basic die head.

[0063] Step (4): Drying. The above honeycomb activated coke wet body was dried in the shade at ...

Abstract

The invention relates to honeycomb-shaped activated coke for flue gas purification and a production method thereof. The effective ingredient of the honeycomb-shaped activated coke is activated coke/carbon, meanwhile other auxiliary additives are added, and the additives include an adhesion agent, a lubricating agent, extrusion aid and a fiber framework. The invention further discloses a preparation method of the honeycomb-shaped activated coke for flue gas purification. Pug with good plasticity is obtained after material mixing and kneading are conducted, then an activated coke honeycomb body is obtained trough extrusion molding, and finally the honeycomb-shaped activated coke is obtained through drying and baking. The honeycomb-shaped activated coke can be used for desulfuration, denitration and other purification processes of boiler flue gas, can greatly lower high wind resistance and high electric consumption in an existing activated coke flue gas process, meanwhile improves the activated coke stack height on the basis of basically maintaining the macro ratio surface and lowers the occupied area of the process, the honeycomb-shaped activated coke for flue gas purification and the production method thereof are simple in preparation process and do not involve a high-temperature process, and strength of the honeycomb-shaped activated coke is increased while energy consumption is lowered.

Description

technical field [0001] The invention relates to an active coke for flue gas purification and a production method thereof, in particular to an active coke for flue gas desulfurization and denitrification and a preparation method thereof. Background technique [0002] With the rapid economic development, the requirements of various countries for environmental protection are also increasing, and energy conservation and emission reduction has become the most concerned environmental protection goal in the world today. In recent years, flue gas purification methods such as desulfurization and denitrification have become important measures for national environmental protection. As the thermal power industry's mandatory boiler flue gas purification treatment is coming to an end, more and more non-thermal power high-temperature process flue gas needs to be treated with desulfurization and denitrification. , and the original traditional desulfurization and denitrification process can ...
