Normal pressure degasser

Abstract

The invention relates to a normal pressure degasser. The normal pressure degasser comprises an air blower, a ventilation device, a jetting device and a slurry pump, wherein the jetting device comprises a tank body, a liquid inlet pipe is vertically arranged in the tank body in a penetration mode, the lower end of the liquid inlet pipe is connected with a vertical tube of the slurry pump, an impacting assembly is arranged at the upper end of the liquid inlet pipe, two ends of the upper part of the impacting assembly are installed on a supporting frame and can vertically move relatively to the supporting frame so as to adjust the distance between the impacting assembly and the end face of the upper end of the liquid inlet pipe, the supporting frame is fixed on the inner circumference of theupper end of the tank body, a slurry outlet is formed in the side end of the tank body, an air inlet of the ventilation device is connected with the upper end of the tank body, and an air outlet of the ventilation device is connected with the air blower. The normal pressure degasser is simple in structure, can regulate the handling capacity according to different degassing requirements, and improves degassing efficiency.

Description

technical field [0001] The invention relates to the technical field of oil drilling equipment, in particular to an atmospheric degasser. Background technique [0002] The degasser is a special equipment used to deal with gas-invasion gas-invasion drilling fluid in oil drilling. At present, the degasser in the domestic oil drilling industry can be divided into two types: atmospheric pressure degasser and vacuum degasser according to the working principle. The commonly used atmospheric degasser is composed of motor, vacuum pump, reducer, slurry discharge shell, separation cylinder, etc. The working principle is that the motor drives the impeller in the separation cylinder to rotate through the reducer, and the impeller drives the gas invasion drilling fluid to rotate. Under the action, the liquid forms a vortex in the separation cylinder, and the gas in the liquid diffuses to the middle and is drawn out by the vacuum pump. This kind of degasser generally requires high precisi...

AI Technical Summary

Problems solved by technology

This kind of degasser generally requires high precision of the transmission shaft and is not easy to process. Because the gas-invasion drilling fluid stays in the separation cylinder for a very short time and the area of ​​the separation cylinder is limited, the degassing efficiency is low, which can only reach 50%. Excellent degassing effect, most of the bubbles do not burst and enter the mud tank with the mud
