Hot roller filter press sludge dehydration and drying machine

Abstract

The invention provides a heat roller filter-pressing type sludge dewatering and drying integrated machine. The machine is provided with a machine base, wherein a sludge dewatering system is arranged on the upper end face of the machine base, a sludge drying system is arranged at the rear end of the sludge dewatering system, a sludge conditioning tank is arranged on the front portion of the upper end face of the sludge dewatering system, a mud-water separation roller concentration barrel is arranged on the rear portion of the upper end face of the sludge dewatering system, the sludge conditioning tank delivers mud and water mixed liquid into the mud-water separation roller concentration barrel through a pipeline for separation and filtration, and the separated and filtered mud and water mixed liquid is delivered to the sludge dewatering system by the mud-water separation roller concentration barrel through an adjusting plate in the mud falling direction to be dewatered, and then delivered to the sludge drying system to be dried. The machine is small in size, low in manufacturing cost, high in automation degree, high in sludge treating and drying efficiency, and capable of providing technical guarantee for achieving harmless, minimized and stable sludge treatment.

Description

technical field [0001] The invention belongs to the technical field of environmental protection machinery, and in particular relates to a hot roller pressure filter type sludge dehydration and drying integrated machine. Background technique [0002] At present, with the overall development of my country's national economy and social undertakings, the country's requirements for environmental protection are also increasing, and the number of urban sewage treatment plants is also increasing. According to incomplete statistics, the sewage treatment surplus of national sewage treatment plants The product - about 10% of the sludge is recycled to the land after being treated by composting, about 20% is landfilled, and a smaller amount is incinerated and used for building materials. The living environment and social development environment bring serious secondary pollution. After decades of development in foreign developed countries, the sludge treatment and disposal technology has b...

AI Technical Summary

Problems solved by technology

As far as the country is concerned, at present, most sewage treatment plants lack good and stable sludge treatment equipment, processes and technologies. Sewage treatment enterprises have sludge dehydration treatment process in their process design, but for those with a moisture content of more than 80% after dehydration Colloidal sludge has not been further treated in a harmless, reduced, and stabilized manner. If it is left to the enterprise to dispose of, the first enterprise does not have too many site resources, and the second is the large amount of external transportation and high cost. In addition, omissions should occur during transportation, which will affect the road and the surrounding environment. The third colloidal high-moisture content sludge will cause secondary environmental pollution and cause secondary natural disasters after being dumped.

At present, although there are large-scale sludge drying equipment, it is difficult to promote it in sewage treatment enterprises, because it has the following main problems: 1. It occupies a large area, has a long construction period, and high investment costs; 2. The odor cannot Complete control; 3. The coal used to generate heat will generate new sources of air pollution; 4. Poor working environment; 5. High energy consumption of equipment and low degree of automation

According to relevant reports, only nearly 10% of the manufacturers in the country have further harmless and resourceful treatment of the sludge after sewage treatment, and the state requires that sludge treatment and disposal must be in accordance with the principle of "stabilization, harmlessness, and resourceful" In order to implement the above principles of sludge treatment and disposal, we must first do a good job in dehydration and drying of sludge, which must be guaranteed by advanced equipment and technology. If there is no advanced equipment and technology, it will directly affect the sewage. Development and improvement of sludge treatment and environmental protection
