Continuous Conveyor Belt Sludge Sewage Dryer

Continuous Conveyor Belt Sludge Sewage Dryer

Nine-Layers Sludge Belt Dryer

 

Item Introduction

  With the ongoing expansion of the urban population and the quick improvement of industrial creation, the quantity of urban domestic sewage and industrial wastewater is rising. In purchase to protect the ecological environment, urban wastewater must be handled and discharged before achieving the regular. Even so, when the sewage is purified, a massive amount of sludge is produced. Given that the sludge has higher water content material and a large quantity and is characterised by a variety of harmful and damaging substances, if it is not safely disposed of, It will deliver serious secondary air pollution to the surroundings. Under typical conditions, the mechanical dewatering technologies of sludge can only reduce the humidity content of sludge to about 80%. These kinds of substantial h2o articles is not conducive to the subsequent transportation and disposal of sludge. As a result, in get to properly treat and recycle the sludge, the sludge drying approach is indispensable.
  Sludge belt dryer is a particular sludge drying tools specially created and designed for sludge which has the attributes of high dampness, large viscosity, higher water keeping capacity, and minimal calorific value. A particular design has been created on the inside structure of the dryer, which not only enhances the thermal efficiency but also successfully avoids the adhesion and excessive drying of the sludge in the dryer.
  Sludge belt dryer is constant drying tools for batch generation, it is specifically suited for supplies with higher drinking water articles and high temperature. The dryers of the series have the rewards of quick drying speed, high evaporation power, and good product top quality. The dehydrated filter cake-like paste content wants to be granulated or strip-formed to be dried.

 

Functioning Theory
  The equipment is a box framework, and a multi-layer conveyor belt is organized in the box, and the conveyor belt circulates in the box. The material is evenly dispersed on the first conveyor belt. Through the transmission of the chain, the 1st layer of the mesh belt is poured into the following layer of the mesh belt, and the reduce layer is alternately dropped one by one particular to the previous layer of the mesh belt. At this time, the dampness articles of the content meets the drying specifications. The air circulation adopts a countercurrent procedure, and the higher temperature and minimal humidity airflow upward from the lowermost mesh belt of the dryer to carry out mass transfer heat transfer, thus obtaining the objective of removing moisture, and the exhaust fuel is discharged from the best through the induced draft supporter. The equipment has a higher diploma of automation, and the supplies are immediately turned more than throughout the drying method to ensure uniform drying of the resources. It has the positive aspects of minimal labor intensity, a good operating surroundings, and easy tools servicing. The base of the box is created with a blanking swash plate and a quick opening cleansing door to facilitate the cleaning of the powder in the box.

  Substance room: The material is placed in the tray framework. The material place is divided from the heating area by an aluminum plate. The gear and the drying space are totally divided. Therefore, the material to be dried does not contact the sulfur dioxide gas, and there is no hearth.
  Heating area: It is a space for putting in electrical heating tools and generating sizzling air. The supporter is mounted at an suitable placement. The enthusiast is forced to flow into the air to make the temperature big difference between the upper and lower sides of the dryer modest. The distinctive adjustable air separation perforated plate guarantees the uniform temperature.
  Very hot air conveying method: The circulating admirer sends very hot air to the hot air passage, and then enters the content chamber by way of the porous air dividing plate, and adopts the air source manner of the higher, lower, still left and right sides to make the drying far more uniform.
  Heating products: electric powered heating, coal burning, fuel, steam, etc. (heating supply can be chosen). The machine has reasonable composition, hassle-free installation, and servicing, steady operation, basic use, long support lifestyle, low running price.
  Air flow and dampness elimination equipment: The equipment is divided into a few sorts: bottom air flow, facet air flow, and top ventilation. It can be designed and manufactured according to different components and plant requirements and geared up with a effective wind direction communication system to make the airflow of the total drying room ample. Temperature control and humidity management in the drying box make sure the suitable temperature for drying, stage handle of drying time, true automation administration, and outfitted with an alarm method.
 

Characteristics

one. The air volume, heating temperature, material residence time, and feeding pace can be adjusted to accomplish the drying result
two. The equipment configuration is adaptable, and the belt washing technique and materials cooling method can be utilised
3. Most of the air is recycled, which will save energy
4. The double-layer air circulation structure is adopted, the hot air is even, and there is no partial dry phenomenon
5. In accordance to the qualities of the substance, various approach movement and added auxiliary equipment can be added
6. Quick-drying speed and higher evaporation depth
seven. The mesh belt has good gas permeability and the drying cycle can be arbitrarily altered
8. In accordance to client needs, it can be divided into many units, every unit can control the loop separately.
9. There are a variety of warmth supply alternatives, these kinds of as steam heating, electric powered heating, heat transfer oil heating, sizzling air heating, etc.
