Description
Technical Field
The utility model belongs to the technical field of gypsum drying equipment, especially, relate to a high-efficient drying device of desulfurization gypsum.
Background
At present, the wet desulfurization process of limestone oxide is adopted for flue gas desulfurization of most coal-fired power plants in China. The gypsum dehydration adopts a two-stage dehydration process, and the process flow is as follows: the gypsum slurry is discharged from the absorption tower and pumped to a gypsum primary dehydration system, and is concentrated and classified by a gypsum hydrocyclone. The concentrated gypsum falls into the feeding distribution system by gravity and is uniformly distributed on the vacuum belt dehydrator, and in the secondary dehydration system, the concentrated gypsum slurry is subjected to vacuum dehydration by the vacuum belt dehydrator. The water content of the gypsum is reduced to below 10% after the gypsum is dehydrated in the part. The dehydrated gypsum is sent to a gypsum storage bin through a gypsum belt conveyor.
Due to the influence of factors such as the operation control of a sulfur dioxide absorption system, the operation state of gypsum dehydration system equipment and the like, the water content of gypsum is generally difficult to be lower than 10%. When the water content of the desulfurized gypsum is high, the desulfurized gypsum has extremely strong viscosity, and is extremely easy to block during the production processes of loading, lifting and conveying. Desulfurized gypsum adheres to various equipment during the production process, causes material accumulation, blockage, influences the normal operation of the production process, and directly influences the commercial application of the gypsum, so that the moisture content of the gypsum must be controlled. Therefore, a high-efficiency drying device for desulfurized gypsum is provided.
SUMMERY OF THE UTILITY MODEL
The utility model provides a high-efficient drying device of desulfurization gypsum, aim at further dries the gypsum after the second grade dehydration, solves the high problem of dewatering system gypsum moisture content.
In order to achieve the above object, the utility model adopts the following technical scheme:
a high-efficiency drying device for desulfurized gypsum comprises a drying cylinder, wherein the drying cylinder is J-shaped, a breaker is arranged at the curve section of the drying cylinder, the outlet of the drying cylinder is connected with a dust remover through a cyclone separator, and the bottom of the dust remover is provided with an ash hopper;
the gypsum falls into a drying cylinder after being broken up by the breaker, and arrives at the cyclone separator after being collided, broken and dried along with the air current, and the cyclone separator separates the gypsum particles which are large in mass and not sufficiently dried and returns to the drying cylinder for further drying, and the gypsum particles which are small in mass and sufficiently dried fall into the ash bucket after being separated by the dust remover along with the air current.
Furthermore, one or more synergy rings are arranged in the vertical section of the drying cylinder.
Further, the ash bucket is connected with a storage bin through a star-shaped feeder, and an automatic bagging device is arranged below the storage bin.
Furthermore, the angle of the curve section of the drying cylinder is 45-90 degrees.
Further, the dust remover is a bag dust remover or an electrostatic dust remover.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses a set up at "J" shape stoving section of thick bamboo bend department and break up the machine, break up the desulfurization gypsum and send out the stoving section of thick bamboo again after, the desulfurization gypsum carries out the drying along with the hot-blast drying in the stoving section of thick bamboo. The drying cylinder is designed into a J shape, so that the desulfurization gypsum is favorably collided and crushed in the drying cylinder to form gypsum particles, and the gypsum is prevented from being blocked in production and transportation. The vertical section of the drying cylinder is provided with the synergistic ring, and the synergistic ring accelerates and then decelerates the airflow of the vertical section, so that the drying effect of the gypsum is enhanced. The dried gypsum is screened by a cyclone separator, the gypsum particles with larger mass or insufficient drying are separated and returned to a drying cylinder for further drying, the gypsum particles with smaller mass and sufficient drying reach a dust remover along with hot air flow, the dust remover separates the gypsum, falls into an ash bucket, is discharged by a star-shaped feeder and is mixed in a storage bin. Through this kind of mode, solve the high problem of traditional desulfurization gypsum moisture content, effectively improved desulfurization gypsum degree of consistency and whole dehydration efficiency, improved product quality.
