Description

Technical Field

[0001] The invention relates to the technical field of drilling cuttings processing, and in particular to a drilling cuttings thermal desorption product condensation processing device and a use method thereof. Background Art

[0002] During the drilling process of shale gas exploration and exploitation, drilling fluid needs to be injected to lubricate and cool the drill bit, build a wall to prevent leakage, and carry rock debris back to the ground. The rock debris returned to the ground is drilling cuttings. Drilling cuttings generally have an oil content of 5% to 20% and a water content of 10% to 20%. They are mostly composed of diesel, water, asphalt, drill cuttings, polymer compounds, and other impurities, and are in a viscous and wet state.

[0003] At present, the thermal desorption process is generally used to process drilling cuttings. After the thermal desorption equipment processes the drilling cuttings, a mixed gas will be produced. The mixed gas is mainly hydrocarbon vapor and water vapor. The mixed gas is then introduced into an alkaline spray tower for condensation, and the condensed liquid is then transported to a condensate treatment device for treatment.

[0004] Existing spray towers generally spray low-temperature liquid directly onto the mixed gas without a deceleration structure, resulting in low condensation efficiency for the mixed gas.

[0023] The present invention divides the interior of the box into an S-shaped channel through a collecting box, thereby increasing the travel of the mixed steam, making it easier for the alkaline liquid sprayed from the atomizing nozzle to condense the mixed steam and neutralize the acid and alkali, thereby improving the condensation efficiency of the mixed liquid.
