Full-automatic hot-air sludge drying equipment and drying method thereof

Abstract

The invention discloses full-automatic hot-air sludge drying equipment and a drying method thereof. The full-automatic hot-air sludge drying equipment comprises a continuous weighing system, an automatic air distribution system, a solid-gas separation system, a main control system and a discharging system. The continuous weighing system is used for detecting a sludge feeding amount and the moisture content of wet sludge; the automatic air distribution system is used for detecting hot air temperature and air inflow quantity; the continuous weighing system and the automatic air distribution system feed data back to the main control system; the main control system calculates the total heat required by sludge drying according to the wet sludge feeding amount, the moisture content of the wet sludge, the moisture content of dry sludge, the hot air inflow quantity and the hot air temperature and then controls the opening degree of a valve in the automatic air distribution system to adjust anair inflow amount, thereby achieveing stable operation of equipment. The full-automatic hot-air sludge drying equipment effectively reduces the workload of manual operation, reduces manual misoperation, prevents a drying tower from being blocked due to insufficient heat in the drying process, and has the advantages of being stable in operation and high in drying efficiency.

Description

technical field [0001] The invention relates to sludge drying treatment technology, in particular to a fully automatic hot air sludge drying equipment and a drying method thereof. Background technique [0002] The sludge drying system is a system that dehydrates and dries sludge with a high moisture content. Its working process is to transport the sludge into the drying host, blow hot air into the drying host through the blower, and fully contact with the sludge to evaporate. The moisture in the sludge makes the sludge dry, and then the dried sludge is discharged for other purposes, while the discharged waste gas enters the solid-gas separation and tail gas treatment system. [0003] The existing sludge drying system also has the following defects: the sludge cannot be continuously and quantitatively sent to the drying tower, and the actual processing capacity of the system cannot be judged, so that the heat required for actual operation and the air volume of the hot air can...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a continuous weighing system using sludge, combined with an automatic air distribution system, in view of the problems that the existing sludge drying system has a large manual operation workload and the drying tower is easy to be blocked. It can not only solve the problem of material blocking in the drying tower, but also effectively reduce the workload of manual operation and reduce the sludge drying equipment that is misoperated by human beings.
