The invention discloses an improved structure of a gypsum dehydration system of a cement wet desulfurization process in a cement industry, comprising a desulfurization tower, a gypsum discharge pump, and a cyclone, wherein the bottom flow port of the cyclone is connected to a dehydration system, and the cyclone The overflow port of the cyclone is connected to the desulfurization tower, the dehydration system includes a venturi feeding device installed directly under the cyclone, and the underflow port of the cyclone is connected to the venturi feeding device through a vertical pipeline. The improved structure cancels the vacuum belt conveyor, gas-liquid separator, filter cloth washing water pump, vacuum pump, filtrate water tank, filtrate water pump and other equipment, only retains the cyclone, adds a venturi feeding device, and cancels the desulfurization complex building ; The cyclone works continuously without adding throttling devices such as valves. The invention saves a lot of desulfurization equipment and site space, reduces one-time investment and operation and maintenance costs, has more reliable operation and simpler system operation.
Description
technical field [0001] The invention belongs to the technical field of cement industry, and is an improved structure of a gypsum dehydration system especially suitable for cement wet desulfurization process in cement industry. Background technique [0002] Limestone-gypsum wet desulfurization process is currently the most widely used desulfurization process, and it is also the most mature and reliable process. The gypsum dehydration system, as the subsequent material processing system of the process, is an important part of the process. The structure principle of the gypsum dehydration system of the existing cement wet desulfurization process in the cement industry can be seen Figure 7 . like Figure 7 It is shown that the gypsum slurry from the gypsum slurry pump of the absorption tower is dehydrated in the first stage through the gypsum cyclone. The underflow of the cyclone is sent to the vacuum dehydrator for dehydration; the overflow of the cyclone is returned to the ...
