Embodiment Construction

[0048] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0049] The invention provides a method for judging the performance of a paddle-type sludge dryer. The paddle-type sludge dryer usually uses steam or heated heat-conducting oil as the drying medium, and uses indirect heating, supplemented by paddle stirring, wherein There are hollow and solid blade designs. In this embodiment, the hollow paddle type sludge dryer to be determined is used to dry the sludge. Assuming that the dryer uses steam as the drying heat source, the structure of the sludge dryer in this embodiment is as follows figure 1 As shown, the sludge dryer performance determination test system in this embodiment includes a paddle-type sludge dryer and an auxiliary measurement system.

[0050] Such as figure 1 As shown, the sludge dryer consists of a casing 1, two paddle-type hollow paddle shafts 2, a driving device 3 and a control cabinet 4. The superheated...

Abstract

The invention relates to a paddle type sludge drying machine performance judgment method. The paddle type sludge drying machine performance judgment method includes the following step: the performance of a sludge drying machine is judged in cooperation with four performance parameters including the drying efficiency, the total heat transferring coefficient, the evaporation speed and the unit sludge drying cost. By means of the paddle type sludge drying machine performance judgment method, the technical blank in the sludge drying machine performance judgment aspect on the market is filled, and the basis is provided for judging the performance of the sludge drying machine. By means of the paddle type sludge drying machine performance judgment method, a client can accurately select the sludge drying machine most suitable for the client according to the requirement of the client, and the sludge drying machine with the better structural characteristics and the better heat transferring characteristic can be selected all the time.

Description

technical field [0001] The invention relates to a method for judging the performance of a paddle type sludge dryer. Background technique [0002] With the development of my country's social economy and urbanization, urban sewage is increasing, and how to deal with sludge as a by-product of sewage treatment has become a major problem in today's society. Due to the late start of sludge treatment and disposal technology in our country, most of the sludge in our country is dumped directly without other treatment methods, which not only seriously pollutes the soil environment, but also poses a serious threat to people's health. [0003] At present, the commonly used sludge treatment methods in the world mainly include: sanitary landfill, agricultural composting, sludge drying and incineration, etc. Among these treatment methods, sludge drying can greatly reduce the volume of sludge, which is convenient for transportation and storage. Therefore, sludge drying has become a key ste...
