Five-Layers Sludge Belt Dryer
Merchandise Introduction
With the continuous development of the city populace and the fast growth of industrial creation, the sum of urban domestic sewage and industrial wastewater is escalating. In purchase to protect the ecological environment, city wastewater mu EPT be treated and discharged ahead of reaching the stHangZhourd. Nevertheless, when the sewage is purified, a massive quantity of sludge is created. Given that the sludge has large drinking water content and a big volume and is characterized by different poisonous and hazardous substances, if it is not safely and securely disposed of, It will bring significant secondary air pollution to the surroundings. Below regular situations, the mechanical dewatering technologies of sludge can only lessen the moisture material of sludge to about 80%. This kind of substantial drinking water articles is not conducive to the subsequent transportation and disposal of sludge. Therefore, in buy to effectively take care of and recycle the sludge, the sludge drying approach is indispensable.
Sludge belt dryer is a particular sludge drying products specifically produced and created for sludge which has the qualities of higher humidity, high viscosity, high water holding capability, and lower calorific worth. The unique design has been made on the inner structure of the dryer, which not only enhances the thermal effectiveness but also efficiently avoids the adhesion and abnormal drying of the sludge in the dryer.
Sludge belt dryer is steady drying products for batch generation, it is specially appropriate for materia EPT with substantial h2o content and high temperature. The dryers of the sequence have the advantages of fa EPT drying speed, high evaporation energy, and good product top quality. The dehydrated filter cake-like paste material demands to be granulated or strip-shaped to be dried.
Functioning Principle
The device is a box structure, and a multi-layer conveyor belt is arranged in the box, and the conveyor belt circulates in the box. The content is evenly distributed on the fir EPT conveyor belt. By means of the transmission of the chain, the fir EPT layer of mesh belt is poured into the next layer of mesh belt, and the lower layer is alternately dropped a single by one to the la EPT layer of the mesh belt. At this time, the dampness content of the substance fulfills the drying specifications. The air circulation adopts a countercurrent method, and the high temperature and low humidity airflow upward from the lowermo EPT mesh belt of the dryer to carry out mass transfer warmth transfer, thus attaining the function of eliminating humidity, and the exhau EPT gas is discharged from the top by means of the induced draft supporter. The gear has a high diploma of automation, and the materia EPT are immediately turned over throughout the drying method to make sure uniform drying of the materials. It has the benefits of lower labor depth, a good working environment, and easy tools servicing. The bottom of the box is developed with a blanking swash plate and a swift opening cleaning doorway to facilitate the cleaning of the powder in the box.
Material room: The substance is placed in the tray structure. The content room is divided from the heating area by an aluminum plate. The gear and the drying room are fully separated. For that reason, the substance to be dried does not contact the sulfur dioxide gasoline, and there is no fire.
Heating place: It is a area for putting in electrical heating equipment and producing scorching air. The fan is set up at an acceptable position. The fan is pressured to circulate the air to make the temperature variation among the upper and reduce sides of the dryer tiny. The distinctive adjustable air separation perforated plate ensures the uniform temperature.
Scorching air conveying method: The circulating supporter sends sizzling air to the sizzling air passage, and then enters the material chamber by means of the porous air dividing plate, and adopts the air offer manner of the higher, lower, still left and proper sides to make the drying far more uniform.
Heating tools: electric powered heating, coal burning, fuel, steam, etc. (heating resource can be picked). The equipment has realistic construction, practical set up, and routine maintenance, steady operation, basic use, long services existence, low functioning cost.
Ventilation and humidity removing gear: The products is divided into 3 varieties: base air flow, facet ventilation, and leading ventilation. It can be designed and manufactured in accordance to different materia EPT and plant requirements and outfitted with a potent wind direction interaction technique to make the airflow of the whole drying space adequate. Temperature handle and humidity manage in the drying box make certain the proper temperature for drying, phase control of drying time, genuine automation administration, and outfitted with an alarm program.
Characteristics
one. The air volume, heating temperature, materials home time and feeding speed can be adjusted to achieve the drying result
two. The gear configuration is flexible, and the belt washing technique and materials cooling program can be utilized
three. Mo EPT of the air is recycled, which will save strength
four. The double-layer air circulation structure is adopted, the very hot air is even, and there is no partial dry phenomenon
five. In accordance to the characteristics of the content, different method flow and additional auxiliary equipment can be extra
six. Rapidly-drying pace and higher evaporation intensity
seven. The mesh belt has excellent fuel permeability and the drying cycle can be arbitrarily altered
eight. In accordance to client wants, it can be divided into numerous units, each and every unit can handle the loop independently.
nine. There are various warmth supply picks, these kinds of as steam heating, electrical heating, heat transfer oil heating, very hot air heating, and so on.
