Device and control method for directly drying sludge by wind power generation

Abstract

The invention provides a device for directly drying sludge by using wind power generation. The device of the invention comprises a power supply system, a MCU control system and a drying system; the power supply system includes a wind power generation power supply part and a power grid power supply part; the drying system includes a drying heating device and a sludge drying chamber, wherein the drying heating device includes a primary-side drying heater and a secondary-side drying heater; and the MCU control system, with detection signals of a wind speed detection module, a wind power generation power detection module and a temperature detection module adopted as input quantities, adjusts the operating speed of a sludge transfer device and the switching on and switching off of a protection circuit through controlling a switch control cabinet to switch the work states of the primary-side drying heater and the secondary-side drying heater. According to the device of the invention, a wind?driven?generator set is adopted to directly supply power for the drying heaters such that sludge can be dried, and therefore, a storage battery storage link can be omitted; and the primary-side drying heater and the secondary-side drying heater of the drying heating device are alternately arranged horizontally, and therefore, the switching of the primary-side drying heater between wind power generation power supply and power grid power supply can be facilitated, and therefore, heating uniformity of the drying heating device in different work modes can be ensured.

Description

technical field [0001] The invention relates to the application field of wind power generation, in particular to a device and a control method for directly drying sludge by using wind power generation. Background technique [0002] With the development of industrial technology, sludge treatment technology is becoming more and more mature. Sludge incineration is a harmless, reduction and resourceful treatment technology. Among them, sludge drying treatment is an important part of sludge incineration. Reducing the cost of sludge drying treatment and improving the efficiency of sludge drying treatment are the primary considerations in the process of sludge incineration. In the general sludge drying process, high-temperature steam and heat transfer oil are often used to dry the sludge. The high-temperature steam and heat transfer oil required in the sludge drying process are mostly provided by industrial boilers. The fuel required by industrial boilers is generally non-renewa...
