AGRICULTURAL AND INDUSTRIAL COMPLEX ENTERPRISES WASTE WATER SEDIMENTS THERMAL TREATMENT DEVICE Russian patent published in 2018 - IPC C02F11/18 

FIELD: technological processes.

SUBSTANCE: invention is intended for the industrial and domestic wastewater sediments, activated sludge or deposits dewatering, and can be used in water supply and drainage. Agricultural and industrial complex enterprises waste water sediments thermal treatment device includes a drainage tower 4, which is a cylindrical column, inside of which transverse inclined lattice partitions 5 are arranged from top to bottom with an opening in the form of a segment in its lower part, which slope direction is alternately changing. In its upper part the drainage tower 4 is provided with the dehydrated sludge 14 supplying pipe, placed at the input to the first upper lattice partition 5, humidified gas-air mixture 15 outlet branch pipe, and in its lower part is with the hot gas-air mixture 16 supply branch pipe and the dry sediment 17 outlet branch pipe. At the slope top the lattice partitions 5 are connected to the tower 4 wall with possibility of changing the slope by means of a tilting device 7 consisting of an eyelet attached to the lattice partition 5, placed between two eyelets fixed to the tower 4 inner wall, through which the support bolt is passed. In the two extreme lower points the lattice partitions 5 are resting against the supports 11, consisting of mounted on the toes elastic elements, attached to the tower 4 inner wall. In front of the drainage tower 4 the gas blower 1 is arranged for biogas supplying, at the inlet connected to the gas-holder and at the discharge is to the injection burner 2. Injection burner 2 injection pipe is connected to the gas-air ejector 3 flaring. Gas-air ejector 3 discharge pipe is connected to the hot gas-air mixture 16 supply branch pipe. Humidified gas-air mixture 15 outlet branch pipe is connected to the plate heat exchanger 18, equipped with a condensate collection pan 19 and made of a corrosion-resistant material.

EFFECT: invention allows to increase the agricultural and industrial complex enterprises waste water sediments thermal treatment device efficiency.
