Sludge treatment equipment
In the sludge disposal project, the initial sludge treatment equipment and infrastructure investment are part of it, and the later sludge disposal cost is also a factor that directly affects the long-term operation of the sludge disposal project. For large and medium sludge disposal projects, the impact of sludge treatment costs is greater. At present, there are traditional ordinary sludge filter presses and new high-pressure diaphragm filter presses on the market.
The cost structure of sludge treatment includes the sludge conditioning fee, the sludge filter press energy consumption cost, the vulnerable parts damage fee, the labor cost, and the treated sludge cake transportation cost.
Traditional sludge filter presses, such as plate and frame filter presses and box-type filter presses, have lower pressures, so lime and a large number of conditioning agents need to be added for sludge modification to reduce the difficulty of sludge dewatering. The Lianyungang Mingke high-pressure diaphragm filter press only needs to add a small amount of quenching and tempering reagent, and the high-pressure diaphragm filter press can completely dewater the sludge.
The traditional sludge filter press has a low degree of automation, and the sludge is not completely dehydrated. The mud cake is easy to stick to the filter cloth. Therefore, the entire treatment cycle is long and the procedure is complicated. It requires a lot of energy consumption and manual operation by workers. Consumption and labor costs occupy a large proportion. The Lianyungang Mingke high-pressure diaphragm filter press operates fully automatically, requiring only one person to operate several equipments, with high sludge treatment efficiency and low energy consumption, so it also saves a lot in this part of the cost.
The body and filter plate of the high-pressure diaphragm filter press are made of high-strength wear-resistant alloy steel, and the filter plate has a service life of up to 10 years. The filter plate of the ordinary sludge filter machine is made of polypropylene, which is difficult to withstand high pressure and is volatile. Life is only about 1 year
After sludge treatment, most of them need to be transported to relevant locations for sludge incineration, production of building materials, production of organic soil and other resources. The sludge with a moisture content of 95% is treated with a high-pressure diaphragm filter press to form a sludge cake with a moisture content of 30% to 60%. After treatment with an ordinary sludge filter press, a sludge cake with a moisture content of 75% -85% is formed. After the homogeneous and same amount of sludge is treated by the high-pressure diaphragm filter press, the output of mud cake is only 37.5% of the ordinary equipment, and the transportation cost of mud cake is also saved by more than half.
From the aspects of the sludge treatment cost, the high-pressure diaphragm filter press has been significantly improved. Therefore, it is not surprising that the comprehensive sludge treatment cost is saved by 50% -70%. In addition, the cost of sludge treatment allows sludge treatment units to quickly recover the cost of sludge treatment equipment, and to carry out sludge treatment without worries about environmental protection. Therefore, when choosing a sludge filter press, the user must comprehensively compare the factors such as the price of sludge filter press, operating cost, and environmental impact.
