Embodiment Construction

[0016] As shown in the figure, the raw flue gas produced by the boiler enters the semi-horizontal dense-phase double tower from the flue gas inlet 4 through the electrostatic precipitator 8, and is continuously added to the material seal layer 9 from the raw material bin 6 under the action of the agitator. The falling activated calcium-based absorbent (desulfurizer) reacts. Here, the function of the material sealing layer 9 is to enable the desulfurizer continuously added from the raw material bin 6 to fall from top to bottom to react with the flue gas, and at the same time prevent the flue gas entering the dry tower from penetrating upward through the material sealing layer to enter the top and bottom of the tower. The flue gas after the reaction is mixed. The flue gas undergoes desulfurization reaction while being stirred by the agitator on one side of the tower. When it reaches the bottom of the tower from top to bottom, it is mass-transferred by the agitator 5 between the ...

Abstract

Disclosed is a dry and half- dry desulfurizer, belonging to the art of environmental protection. The invention adopts dolostone as the desulfurizer, the content of the main component calcium carbonate of dolostone being among 40%- 90%, the dolostone being jevigated into powder particle among 100- 600 mesh, which is then added into the dense-phase desulfuration system. The merit is that: (1) the adhesive force of dolostone particle is light, avoiding the problem of shell clinging and caking of desulfurizer; (2) dolostone particle is loose, and has a perfect contact with sulfur dioxide, lightening the stirring of the stirrer, and decreasing the energy consumption; (3) compared with calcium hydrate, the dolostone deletes the agglutination process, and has a broad natural resource and a low cost.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a dense phase coherent semi-dry desulfurizer. Background technique [0002] Dense phase desulfurization technology is a new type of dry semi-dry desulfurization technology. The desulfurization agent used in it is powdered calcium hydroxide, and its desulfurization efficiency can be as high as 90%. This kind of desulfurizer has the problems of "sticking to the wall" and "caking", and its desulfurization equipment is huge, the energy consumption is high, and the desulfurization cost is also high. Contents of the invention [0003] The purpose of the present invention is mainly to solve the problems of "sticking walls", "caking", huge desulfurization equipment, high energy consumption and high desulfurization cost in the original dense-phase tower desulfurization system using calcium hydroxide as desulfurizer. [0004] A dense coherent semi-dry desulfurizer, ch...
