Problems solved by technology

Due to the above advantages of the paddle-type sludge dryer, the paddle-type sludge dryer has been more widely used than the other two sludge dryers. It is currently an ideal sludge drying stand-alone equipment, but the paddle-type The sludge dryer is an intermittent operation equipment with a single function, which cannot realize continuous sludge drying. The tail gas after drying by a single machine is directly discharged into the atmosphere, causing pollution and waste of valuable components, and cannot realize integrated treatment functions such as tail gas treatment. , so there is an urgent need for a complete set of sludge drying treatment equipment that can realize integrated treatment of sludge

Abstract

The invention relates to a treatment device of sludge drying in the field of environmental protection, in particular to a set treatment device of sludge drying, comprising a paddle sludge drier (1) with a feeding inlet (4), a discharging hole (5), a steam inlet pipe (6), a water outlet pipe (7), a tail gas outlet (8), a cylinder (9), a hollow shaft (10) and hollow paddles (11); the hollow paddles (11) are arranged on the hollow shaft (10); the set treatment device of sludge drying also comprises a storing and feeding device (2) and a tail gas purifying processing device (3); the discharging hole (12) of the storing and feeding device (2) and the feeding inlet (4) of the paddle sludge drier (1) are connected; and the tail gas outlet (8) of the paddle sludge drier (1) and the gas inlet (13) of the tail gas purifying processing device (3) are connected. The treatment device has the advantages of simple structure, good drying effect, low cost, environmental protection, high cost performance, continuous drying and realization of sludge integrated treatment.

Description

technical field [0001] The invention relates to a sludge drying treatment device in the field of environmental protection, in particular to a sludge drying complete treatment device. Background technique [0002] Sludge is a by-product of sewage treatment, and the amount of sludge is huge. The amount of sludge produced by domestic sewage treatment in my country alone reaches hundreds of millions of tons, plus papermaking sludge, printing and dyeing sludge, and manufacturing sludge produced by industrial sewage treatment Industrial sludge such as leather sludge and oil sludge, the amount of sludge is even greater. Sludge has the characteristics of high water content and complex components. Sludge generally contains lost valuable raw materials and latent heat, and at the same time enriches high concentrations of heavy metals and other pollutants. If the traditional method of direct incineration is used to treat high water content For sludge treatment, the sludge needs to be co...
