The significance of sludge dryer:
sludge is a solid precipitate produced by water and sewage treatment. Its main characteristics are as follows: high water content (up to 99%), high organic matter content, easy to rot and stink, fine particles, small specific gravity, colloidal liquid. According to the sources, sludge mainly includes domestic sewage sludge, industrial wastewater sludge and water supply sludge. The disposal and treatment of various kinds of sludge has become a persistent disease restricting the development and sanitation of cities.
With the strengthening of national energy conservation and emission reduction, the improvement of national environmental protection awareness, and the increasing output of urban sludge, sludge disposal and development and utilization have become an important issue of national environmental protection. With the development of sludge drying technology, it is possible to use sludge for agriculture, fuel and incineration. The improvement and innovation of sludge drying technology and sludge dryer directly promote the development of sludge disposal means, expand the selection range of sludge disposal means, and ensure its safety, reliability and sustainability. Changzhou Haomai drying Engineering Co., Ltd. has always been in the forefront of sludge environmental protection treatment technology. The energy-saving and environmental protection sludge dryer can dry the sludge to the required moisture, which is convenient for the production and manufacture of sludge bio organic fertilizer. It is the dryer equipment of organic fertilizer manufacturing enterprises.
Sludge dewatering and drying:
Sludge dewatering is an important part of the whole sludge treatment process. In order to achieve the optimal effect of sludge dewatering and drying, Changzhou Haomai drying Engineering Co., Ltd. introduced advanced sludge drying technology from abroad, and combined with the actual situation in China, the sludge special paddle dryer manufactured by Changzhou Haomai drying Engineering Co., Ltd. can fully meet the requirements of industrial customers and is trusted and cooperated by more and more enterprises, We have cooperated with many large, medium and small enterprises in China. We will continue to innovate and provide better service for our customers with exquisite technology and high quality service.
Summary of sludge special hollow paddle dryer:
Because the shape of mixing blade is similar to paddle, it is called paddle dryer. It is also called trough dryer or stirring dryer abroad.
Working principle of hollow paddle dryer:
the heat transfer surface of hollow paddle dryer includes blade, mixing shaft and wall surface, and the heat transfer area of blade accounts for a large part. Therefore, the equipment has compact structure and large heat transfer area per unit volume. The temperature of hot medium ranges from - 40 ℃ to 320 ℃, which can be steam or liquid type, such as hot water, heat transfer oil, etc. Indirect conduction heating, without carrying air to take away heat, heat is used to heat materials. The heat loss is only the heat dissipation to the environment through the insulation layer. The shell of the pulp dryer is Ω type, and two to four hollow mixing shafts are arranged in the shell. The shell has a sealed end cover and an upper cover to prevent the leakage of material dust. The heat transfer surface of wedge blade has self-cleaning function. The relative movement of material particles and the wedge-shaped surface produces a washing effect, which can wash off the attached materials on the wedge-shaped surface, and keep a clean heat-transfer surface during operation.
Features of sludge dryer:
1. Because the heat needed for drying the equipment is indirectly heated by heat conduction, the drying process does not need or only needs a small amount of gas to remove the moisture. It is a kind of energy-saving drying equipment, which greatly reduces the heat loss taken away by the air flow and improves the heat utilization rate.
2. Mixing and mixing make the materials turn violently, so that the heat transfer coefficient is very high, so the floor area and space are very small, and the construction cost of the workshop is saved. In the drying process, the gas consumption is small, the flow rate is low, and the amount of dust taken away by the gas is small, so the gas dust recovery after drying is convenient, and the recovery equipment volume is small, which can save equipment investment. For the drying process which needs to recover solvent, the solvent concentration can be greatly increased. Due to the special structure of paddle blade, the material is squeezed and relaxed alternately in the drying process, which strengthens the drying. The material filling rate in the drying chamber is very high, which can reach 80% - 90%. The residence time of materials can be adjusted from a few minutes to a few hours by adjusting the feeding speed, stirring shaft speed, material filling degree and other parameters.
The sludge dryer can be used for sludge drying of municipal sludge, printing and dyeing sludge, papermaking sludge, electroplating sludge and other fields, with high thermal efficiency, wide application range, low operation cost and continuous production.
