Combined device for drying and pyrolyzing sludge and tyre plastics with packing augers parallelly arranged in overlaid manner

Abstract

The invention provides a combined device for drying and pyrolyzing sludge and tyre plastics with packing augers parallelly arranged in an overlaid manner. The combined device is composed of a packing auger I, a packing auger II, a packing auger III, a packing auger IV, a packing auger V, a packing auger VI, a partition plate I, a partition plate II, a slag remover, a reactor III, a reactor II, a reactor I and a feed inlet, wherein the reactor I is connected to the reactor II and the reactor I and the reactor II are separated by the partition plate I; the reactor II is connected to the reactor III and the reactor II and the reactor III are separated by the partition plate II; the packing auger V and the packing auger IV are arranged in the reactor III; the feed inlet is formed in the upper portion of the reactor I, and the slag remover is arranged on the tail end of the lower portion of the reactor III. The plurality of packing augers are arranged in the reactors to spirally propel more materials, and the plurality of reactors are overlaid, so that the device is accelerated to operate at a rated temperature, and therefore, the capacity is increased.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a combined device in which augers are arranged side by side and stacked for drying and pyrolyzing sludge and tire plastics Background technique [0002] my country's cities and rural areas discharge a large amount of sewage every day. The sewage contains a small amount of sludge. These activated sludge generally still contain about 70-80% of water after dehydration. Direct discharge will cause secondary pollution because the water content is too high. At present, kiln drying methods and equipment are mostly used for sludge dehydration; due to the high moisture content and strong cohesiveness of sludge, it is easy to form agglomerates and adhesive layers in the drum reactor, which seriously affects drying and normal operation, and needs to be invented A dehydration and drying device with high efficiency and good dispersion. Contents of the invention [0003] The purpose of the...
