Description

A smoke-tight rotary joint

technical field

The utility model relates to the technical field of oily waste treatment, in particular to a flue gas sealing rotary joint.

Background technique

At present, a large amount of oily sludge is unavoidably produced in the process of crude oil production and refinery production in oilfields. These oily sludge sands are complex in shape, including solid, semi-solid, fluidized slurry and other forms, and have complex components, including crude oil, water, chemical additives and other components. The existing methods for treating oil sludge mainly include incineration method, solidification method, compound fertilizer method, reinjection method, oil washing method, microbial method, land cultivation method, cracking method, etc. The utility model adopts a cracking treatment process to process oil sludge deal with.

The pyrolysis method is a commonly used process for treating oil sludge at home and abroad. Its essence is to use high temperature to heat the oily sludge sand in a closed container to decompose the organic matter into recyclable oil gas and residual carbon containing heavy oil. The core of the pyrolysis method is mainly the choice of heating method. I learned that the current heating method on the market includes a burner to heat the heat transfer oil, and the heat transfer oil passes through the auger shaft to heat the material. Due to the limited heating temperature of the heat transfer oil, cracking cannot be handled. Oil sludge with a temperature as high as 600°C, so the heating method of heat transfer oil has certain requirements on the composition of the processed materials. Another heating method is to generate high-temperature flue gas through burner combustion, and pass the flue gas into the shaft of the auger to heat the material. Due to structural limitations, the material will not be cracked sufficiently when heated by high-temperature flue gas, and the material after heating High-temperature flue gas exhaust temperature is high, which makes the material treatment results not ideal and causes a lot of waste of heat energy.

Therefore, how to reduce the heat waste of high-temperature flue gas has become a technical problem to be solved urgently by those skilled in the art.
