Problems solved by technology
[0004] Aiming at the deficiencies of the prior art, the present invention provides a low-temperature and high-efficiency sludge drying process and device, which solves the problem that the existing sludge treatment process has a high moisture content and is inconvenient for subsequent sludge treatment, which cannot be effectively Solve the problem of the diffusion of toxic and harmful gases generated in the sludge drying process to the outside. It is not environmentally friendly and makes the adaptability of the drying process poor. It can only be applied to sludge with relatively simple components, and the drying process consumes more energy. The problem

Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0029] see Figure 1-3 , the present invention provides a technical solution: a low-temperature high-efficiency sludge drying process, comprising the following steps,
[0030] (1) Sending in the sludge, sending the sludge into the drying box through the sludge pump, and using the plate and frame machine to perform preliminary solid-liquid separation of the sludge in the drying box;
[0031] (2) Low-temperature drying, the external air is drawn and heated by t...

The invention discloses a low-temperature and high-efficiency sludge drying process and device, and relates to the technical field of sludge drying. The process comprises the following steps: feedingsludge, low-temperature drying, hot air circulation, and finished product processing. The device comprises a hot air blower, wherein an air outlet of the hot air blower communicates with a mixing box,and the air outlet of the mixing box communicates with a drying box. The low-temperature and high-efficiency sludge drying process and device can improve the drying degree of sludge, avoids the problem that the sludge treated by the existing sludge treatment process has a high water content and is inconvenient for subsequent treatment, reduces the energy loss of the process, can prevent toxic andharmful gases generated during the sludge drying process from diffusing to the outside, and solves the problems that the existing drying process has poor adaptability and can only be applied to sludge with simpler composition. At the same time, the low-temperature and high-efficiency sludge drying process and device are close to natural drying, more in line with environmental protection and sanitation requirements, and more suitable for environmental treatment projects such as river sludge cleaning, and can help to generate beneficial microorganism to improve the river water quality.
Description
technical field [0001] The invention relates to the technical field of sludge drying, in particular to a low-temperature and high-efficiency sludge drying process and device. Background technique [0002] Sludge drying is a necessary intermediate process of sludge treatment. From direct application to direct incineration, from application after drying, to incineration after drying, until the latest gasification after drying, drying is basically affirmed as a There are two main reasons for the importance of the necessary intermediate process: economy, whether it is the reduction of transportation and disposal, or the reduction of energy consumption; sanitation, the necessary conditions for agricultural use, most of the sludge dewatering in the industry currently only uses mechanical extrusion Press-type sludge dewatering, such as belt filter press, plate and frame filter press, screw stacker and centrifugal dewatering machine, the moisture content of the sludge after dehydrat...
