Technical introduction

Leather industry must be mentioned when talk about environmental cause. Leather is a kind of non-perishable matter which is made from animal skin after a series of physical and chemical disposal such as unhairing and tanning. Leather is composed of natural protein fibers which closely compile with each other in a three-dimensional space. There is a special grain layer which is characterized by natural grain and gloss on the surface of leather. Leather is a kind of requisite thing in modern society. However, leather industry produces much sewage and sludge which need to be disposed deeply. The sewage disposal for leather produces a great amount of leather sludge. Most materials used in leather processing are auxiliary ingredient, limestone, sodium sulfide, ammonium salt, vegetable tanning materials, pro-tease and etc. as a result, COD content is higher in leather sludge which will affect environment severely. According to relevant national requirements, leather sludge should be uniformly recycled by qualified companies. For large-scale leather enterprises, the disposal cost for leather sludge is too high to afford. At present, most people choose to dry the leather first by leather dryer in order to improve the convenience of disposal, reduce weight and control recycle expense. 

Advantages

1. Overcome high temperature; good high temperature performance; solve problems of winter frost and bad high temperature performance;
2. Adopt intermediate heat transfer and temperature gradient in double effect and triple effect dehumidicating technology; the comprehensive dehumidicating ratio (SMER) reaches to over 20%;
3. Solve problems of traditional device such as bad dehumidifying performance, or even no dehumidifying problem;
4. According to different moisture content of sludge cakes, different technologies can be adopted. Drying time of sludge cakes is reduced and comprehensive performance of dryer is improved;
5. Special mesh type low temperature drying mode: safer; longer service span; advanced strafified air distribution; advanced dust proof technology; efficient and stable performance; 
Leather Sludge Dryer
6. Can fully fulfill the aims of reduction, stabilization, harmlessness and reclamation of sludge. final granularities can be used as fertilizer, fuel, incineration, building materials, biomass materials, soil for landfill and land utilization;
7. Can be applied to various sludge drying system (including sludge containing much sand); long service span; can dry sludge cakes with 83% moisture content to sludge granularity with 10% moisture content; by using special sludge forming technology, sludge can be reduced to 1/4 to 1/5; according to different solidification rate, adopt different material distributing modes;
8. Low temperature (40 to 75); fully closed drying technology; no tail gas discharged; the drying process is carried out in a closed environment; no air is discharged into outer environment; no secondary pollution caused; low temperature technology can fully avoid the vitalization of various organic in sludge; avoid the emission of foul gas;
9. Safe running system; no risk of explosion; the oxygen content in this process is below 12%; the concentration of dust is blow 60g/cubic meters; the temperature of granularity is below 75 degree centigrade; the transferring speed of mesh can adopt frequency conversion; the moisture content is adjusted between 10% to 30%; can meet requirements of various processes;
