CN101880564A - Sludge biomass synthetic fuel and preparation method thereof - Google Patents

Abstract

The invention provides sludge biomass synthetic fuel. The fuel comprises the following raw materials in percentage by weight: 10 to 40 percent of sludge, 10 to 50 percent of charcoal powder and 30 to 60 percent of vegetable fiber. The method for preparing the sludge biomass synthetic fuel comprises the following steps of: 1, disinfecting and deodorizing the sludge and drying the sludge until the water content of sludge is less than 40 percent; and 2, mixing the sludge treated by the step 1 with charcoal powder and vegetable fiber in a weight ratio, or then performing formation processing. The sludge biomass synthetic fuel has the advantages of recycling sludge, changing the waste into the valuable, relieving environmental pollution caused by sludge, along with high burning temperature, wide application range, large transportation radius, extremely low sulfur content, extremely low SO2 emission during burning, low ash content and low dust pollution; and the fuel of the invention is clean fuel.

Description

A kind of sludge biomass synthetic fuel and preparation method thereof

Technical field

The present invention relates to a kind of sludge biomass synthetic fuel and preparation method thereof.

Background technology

At present, the sludge fuel utilization, main mode has three classes: the one, the mud after the oven dry mixes directly with powdered biomass and acts as a fuel, or passes through forming process; The 2nd, the mud after the oven dry mixes directly with raw coal and acts as a fuel, or passes through forming process; The 3rd, the mud after the oven dry mixes directly with biomass, raw coal by a certain percentage and acts as a fuel, or passes through forming process.The calorific value of the resulting fuel of these methods is 3000kcal/kg-4200kcal/kg, and calorific value is low, and unit calorific value cost is higher, has influenced the sale radius of product, and the ash content height; Second class, the 3rd class A fuel A sulphur content are higher.

Summary of the invention

Purpose of the present invention is that a kind of sludge biomass synthetic fuel and preparation method thereof will be provided, and this fuel value can reach 6000kcal/kg, and unit calorific value cost is low, and sulphur content is lower than 0.02%, belongs to clean energy, the cost performance height, and radiation scope is big.

A kind of sludge biomass synthetic fuel of the present invention, the weight percent of its various raw materials is: mud 10%-40%, wood charcoal powder 10%-50%, vegetable fibre 30%-60%.

Mud of the present invention comprises mud, river mud, industrial organic sludge, the ight soil that sanitary sewage disposal produces.

The preparation method of a kind of sludge biomass synthetic fuel of the present invention:

1) described mud through sterilization, deodorizing, dry to water content and be lower than 40%;

2) mud that step 1) was handled mixes by above-mentioned weight percent with wood charcoal powder, vegetable fibre or and through forming process.

The invention has the beneficial effects as follows,, turn waste into wealth, reduce the pollution of mud environment with the recycling sludge utilization; The temperature of combustion height, suitable application area is wide, and transportation radius enlarges; Sulphur content is extremely low, during burning SO2 discharging extremely low, be clean fuel; Ash oontent is low, and dust pollution is little.

Embodiment

A kind of sludge biomass synthetic fuel of the present invention and preparation method thereof, described mud comprise mud that sanitary sewage disposal produces, river mud, industrial organic sludge, ight soil etc.Earlier with described mud through sterilization, deodorizing, dry to water content and be lower than 40%; With the mud of handling, with wood charcoal powder, vegetable fibre, be by weight percentage: mud 30%, wood charcoal powder 35%, vegetable fibre 35% mix or and through forming process, be sludge biomass synthetic fuel, its high heating value, being one of best mode of recycling sludge utilization, is the perfect adaptation of energy-saving and emission-reduction and environmental protection.

Claims (3)

1. sludge biomass synthetic fuel, the weight percent of its various raw materials is: mud 10%--40%, wood charcoal powder 10%-50%, vegetable fibre 30%-60%.

2. according to the described a kind of sludge biomass synthetic fuel of claim 1, it is characterized in that: described mud comprises mud, river mud, industrial organic sludge, the ight soil that sanitary sewage disposal produces.

3. the method for preparing claim 1 or 2 described a kind of sludge biomass synthetic fuels:

1) described mud through sterilization, deodorizing, dry to water content and be lower than 40%;

2) mud that step 1) was handled mixes by the described weight percent of claim 1 with wood charcoal powder, vegetable fibre or and through forming process.
