Big Capacity Automatic Industrial Drying Equipment No Fuel Consumption

Comprehensive Utilization Of Waste Heat Automatic Industrial Drying Equipment

System Introduction:

At present, the direct emission of high temperature flue gas, steam occurs in lots of printing and dyeing

factories, power plants, which is a great waste of thermal energy. At the same time, there is a need for

the drying of sewage sludge or other materials, which will consume a lot of fuel to supply heat. It will

have great significance to reduce the environmental pollution and to alleviate economic pressure of

enterprises by making effective use of the waste heat to dry the wet materials. Different factories are

with different tail gas temperature, most of them is between 120 and 500.

Process Flow:

The scheme for maximizing the utilization of system thermal energy can be designed as per different

material, waste heat temperature and waste heat flow.

Cases 1: 200T/D Sludge Processing Project for one of Dalian Petrochemical Companies, and exhaust

flow: 750000 Nm³/h; exhaust temperature: 135; Our design is to use three sets of Φ4 x 32m dryer,

which have been put into production.

Case 2: 4T/D Sludge Processing Project for one of Shanghai dyeing factories, exhaust flow:

10000Nm³/h, exhaust temperature:180; Our design is to use Φ2 x 5m intermittent dryer, which has

been put into production.

System Advantages:

Waste heat utilization, energy saving and environmental protection; No fuel consumption, few power

consumption, the original dust removal system can be used to save investment; Obtain raw material

locally, additional land is not required; High level of automation, laborsaving; Drying time can be

adjusted, and the water content can be controlled after drying; PLC automatic control system can be

adopted in the entire system, which contains advanced testing equipment, thermometer, temperature

control device, fault alarm and automatic shutdown protection etc.
