Airtight tank type decoking dehydration tank

Abstract

The invention relates to an airtight tank type decoking dehydration tank, which comprises a cylinder, a top cover and a taper cylinder under the cylinder. The top cover is equipped with a material inlet, the small end of the taper cylinder is equipped with a material outlet, the cylinder is internally equipped with an overflow assembly, and overflow holes are disposed on the side wall of the cylinder; the taper cylinder is internally equipped with a plurality of water filtration assemblies, each water filtration assembly includes two long strip-shaped supports attached to the inner wall of thetaper cylinder, two sets of rib plates are cooperatively arranged on the two supports in a spaced mode, the two sets of rib plates are perpendicular to each other in the length direction, and screenholes formed by cooperation of the two sets of rib plates are utilized for water filtration, a plurality of water outlet pipes and an annular pipe are connected to the side wall of the taper cylinder,and the bottom side of the annular pipe is equipped with a plurality of water outlets; the side wall at the bottom of the taper cylinder is equipped with a plurality of bottom water filtration ports,which are located below the annular pipe and are internally equipped with a cylindrical filter plate assembly; and the taper cylinder is internally equipped with an anti-blocking device for partitioning the inner cavity of the taper cylinder so as to prevent materials from blocking the outlet. The airtight tank type decoking dehydration tank provided by the invention can achieve efficient and environment-friendly dehydration and smooth transportation of petroleum coke.

Description

technical field [0001] The invention relates to the field of petroleum coke production devices, in particular to a closed tank type decoking and dehydrating tank. Background technique [0002] In the existing decoking technology, petroleum coke is transported from the coke tower to the open-air coke storage pool for storage and dehydration. The dehydration process is natural dehydration in the open air. The entire dehydration process is uncontrollable, and a large amount of waste gas and coke powder particles will be generated during the dehydration process. The atmospheric environment is seriously polluted, which is harmful to the health of the personnel working on site; after the dehydration is completed, the petroleum coke is transported by a grab crane or a screw conveyor. The entire transport process is time-consuming and laborious, and dust is easily generated on site. There is a lack of a petroleum coke dehydration device that can efficiently and environmentally frien...
