Dustproof and explosion-proof pelleting and drying equipment for oily sludge

Abstract

The invention discloses dustproof and explosion-proof pelleting and drying equipment for oily sludge. The equipment comprises a pelleting cabin and a drying cabin, multiple roller cylinders are horizontally installed in the pelleting cabin, and a motor A is installed at the exterior of the pelleting cabin; a feeding port is formed in the upper portion of the pelleting cabin, and a thermometer A and a pressure gauge A are installed at the feeding port; a rotation shaft is vertically installed in the drying cabin, a motor B is connected to the bottom of the rotation shaft, and a small heating disc and a large heating disc are alternatively installed on the rotation shaft; multiple rake arms are distributed on the small heating disc and the large heating disc from the center to the exterior,multiple rake blades are vertically installed on the rake arms, and a discharging port is formed in the lower end of the drying cabin; a thermometer B, a pressure gauge B and a combustible gas concentration detection meter are installed on the side wall of the drying cabin; communicated steam pipes are arranged in the pelleting cabin and the drying cabin. The dustproof and explosion-proof pelleting and drying equipment has the advantages that the safety is high, the running maintenance cost is low, the low-quality heat source can be used, the products are good in quality, and the water treatment amount in the later period and the water demand amount are small.

Description

technical field [0001] The invention relates to the technical field of granulation and drying of oily sludge, in particular to a dust-proof and explosion-proof oily sludge granulation and drying equipment. Background technique [0002] Oily sludge refers to sludge mixed with heavy oil such as crude oil, various refined oils, and residual oil. Oily sludge is not inherent in nature, but due to various accidents, improper operation, Old, damaged, corroded equipment causes crude oil and refined oil to escape, leak, drip, leak, leak to the ground, deposit on the bottom of oceans, lakes, rivers, and mix with soil, water, etc. to form oil and soil. water, even in mixtures with other pollutants such as [0003] Oily sludge is harmful to the human body, plants and aquatic organisms. The oil and gas evaporated in the air can irritate the skin, eyes and respiratory organs, and make the land lose the function of plant growth. It is difficult to deal with and repair. It is the main oil...

AI Technical Summary

Problems solved by technology

In recent years, some oily sludge drying granulators have appeared on the market. Because it is oily sludge, safety hazards such as explosions are prone to occur during the treatment process. Therefore, the inventors have designed a dust-proof and explosion-proof oily sludge dryer Sludge granulation and drying equipment
