Five-Levels Sludge Belt Dryer

Product Introduction

  With the continuous expansion of the urban inhabitants and the speedy advancement of industrial production, the volume of urban domestic sewage and industrial wastewater is increasing. In buy to safeguard the ecological atmosphere, city wastewater have to be dealt with and discharged ahead of reaching the standard. Nevertheless, when the sewage is purified, a massive volume of sludge is generated. Since the sludge has high drinking water articles and a huge quantity and is characterized by different harmful and harmful substances, if it is not properly disposed of, It will provide severe secondary pollution to the environment. Below standard situation, the mechanical dewatering technology of sludge can only minimize the humidity content material of sludge to about eighty%. Such high h2o content material is not conducive to the subsequent transportation and disposal of sludge. Therefore, in purchase to properly deal with and recycle the sludge, the sludge drying method is indispensable.
  Sludge belt dryer is a specific sludge drying products specially created and created for sludge which has the attributes of high humidity, high viscosity, higher h2o keeping capability and reduced calorific value. The unique style has been made on the inside composition of the dryer, which not only enhances the thermal efficiency but also efficiently avoids the adhesion and too much drying of the sludge in the dryer.
  Sludge belt dryer is steady drying equipment for batch generation, it is specially suited for materials with higher h2o content material and substantial temperature. The dryers of the sequence have the advantages of rapidly drying velocity, higher evaporation energy, and good item high quality. The dehydrated filter cake-like paste substance demands to be granulated or strip-formed to be dried.

Functioning Theory
  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 first conveyor belt. Through the transmission of the chain, the first layer of mesh belt is poured into the following layer of mesh belt, and the reduced layer is alternately dropped one by one to the very last layer of the mesh belt. At this time, the dampness articles of the material fulfills the drying specifications. The air circulation adopts a countercurrent process, and the high temperature and reduced humidity airflow upward from the lowermost mesh belt of the dryer to carry out mass transfer heat transfer, thereby achieving the goal of removing moisture, and the exhaust gas is discharged from the best through the induced draft admirer. The equipment has a substantial diploma of automation, and the supplies are routinely turned in excess of during the drying approach to make sure uniform drying of the supplies. It has the rewards of lower labor depth, a great operating atmosphere, and basic equipment maintenance. The base of the box is made with a blanking swash plate and a fast opening cleaning door to aid the cleansing of the powder in the box.

  Content space: The substance is placed in the tray framework. The materials place is separated from the heating space by an aluminum plate. The equipment and the drying space are fully separated. As a result, the materials to be dried does not touch the sulfur dioxide gas, and there is no fireplace.
  Heating place: It is a room for installing electric heating products and generating scorching air. The supporter is put in at an suitable placement. The fan is forced to flow into the air to make the temperature big difference among the higher and lower sides of the dryer tiny. The distinctive adjustable air separation perforated plate guarantees the uniform temperature.
  Very hot air conveying mode: The circulating admirer sends very hot air to the scorching air passage, and then enters the materials chamber by way of the porous air dividing plate, and adopts the air offer mode of the higher, reduced, still left and proper sides to make the drying a lot more uniform.
  Heating tools: electrical heating, coal burning, gas, steam, etc. (heating source can be chosen). The equipment has reasonable construction, hassle-free installation, and servicing, stable procedure, simple use, prolonged provider daily life, reduced functioning value.
  Air flow and humidity elimination tools: The products is divided into a few sorts: base air flow, facet air flow, and best ventilation. It can be developed and produced in accordance to distinct supplies and plant requirements and outfitted with a potent wind route conversation method to make the airflow of the entire drying area ample. Temperature management and humidity manage in the drying box guarantee the suitable temperature for drying, stage control of drying time, actual automation management, and geared up with an alarm technique.
