Abstract

The invention discloses waste catalyst mud water dehydration treatment equipment and a waste catalyst mud water dehydration treatment method, and belongs to the technical field of solid-liquid separation in environmental engineering. The equipment comprises a sludge conveyer device, a complexing agent feeding device, a flocculating agent feeding device and a coiled dehydration device. The technique method comprises the following steps: conveying waste catalyst mud water; adding a complexing agent and a flocculating agent; and carrying out mixing reaction, and coiled dehydration. The moisture content of the waste catalyst mud water can be reduced to about 50% from 99.5% once by only adding the compounded medicine and combining with a coiled dehydration manner. According to the technique and the equipment, deep dehydration is carried out on the waste catalyst mud water; the treatment cost of the sewage is reduced; and a good way is provided for reduction treatment of a waste catalyst. Compared with an existing dehydration technology of combining filtration with a vacuum belt dehydrator, the technology is not easy to block, small in floor area, simple to operate, high in automatic degree and low in operation cost, and does not generate secondary pollution.

Description

technical field [0001] The invention relates to a method for dehydrating waste catalyst muddy water and treatment equipment thereof, in particular to a waste catalyst muddy water treatment method which combines high-efficiency compound medicament with stacking screw dehydration. Background technique [0002] The catalytic cracking unit in the refinery is one of the main processing units for heavy oil processing. Catalyst consumption and replacement is one of the main operating characteristics of the unit. The normal fresh catalyst consumption is 0.6-1.4kg / t raw material, while the catalyst consumption of 0.3-0.6 kg / t raw material It is lost to the atmosphere through the chimney. As the national environmental protection regulations become more and more strict, the emission indicators of SO2, NOX and dust content in the chimney of the catalytic device are strictly controlled. Flue gas desulfurization and denitrification technologies are being used at home and abroad to meet t...
