Sludge drying treatment equipment and method

Abstract

The invention discloses sludge drying treatment equipment and method. The equipment comprises a sludge jet device, a jet combustion system, a drying device, a finished product conveying device and a dust removal device, wherein the sludge jet device comprises a wet material yard, a sludge jet machine and a sludge jet feeding hole; the jet combustion system comprises a fire coal grinder, an ignition device, a jet machine, a combustor and a control cabinet; the drying device comprises a rotary drum type drying machine, a rotary supporting roller and a rotary mechanism; the finished product conveying device comprises a belt conveyer and a finished product storage yard; the dust removal device comprises a cyclone dust remover, a belt type dust remover, a carbon adsorption deodorizer and a chimney. According to the equipment, various pathogenic bacteria, worms and eggs in sludge can be all killed, the fertilizer efficiency in the sludge also can be kept, and the sludge is turned into very good organic compound fertilizer; moreover, the equipment is convenient to transport, stack and store.

Description

technical field [0001] The invention relates to the field of sludge regeneration treatment, in particular to a sludge drying treatment equipment and method. Background technique [0002] Sewage produced by urban life and industrial production will produce a lot of sludge during the treatment process of sewage treatment plants. The untreated sludge has high organic content, is perishable, contains parasites and eggs, various microorganisms and various Heavy metals, salts, polychlorinated biphenyls, dioxins and other toxic and harmful substances that are difficult to degrade will cause secondary pollution to the environment if they are not properly treated and discharged arbitrarily. [0003] At present, the following methods are mainly used for sludge treatment all over the world: random stacking, landfill, river and ocean discharge, etc. Each method has its own advantages and disadvantages, but they all have a common disadvantage, that is, secondary pollution to the environm...
