Coalification furnace gas-liquid separator

煤化炉气液分离装置

Abstract

The utility model discloses an important device of coalification furnace, namely, a coalification furnace gas-liquid separator. The coalification furnace is used for the cleaning and combustion of coal in the cleaning coal industry. The coalification furnace gas-liquid separator consists of a housing 1, a gas outlet pipe 2, a crude gas inlet pipe 3, a connecting reinforcement 4, an annular jet pipe 5, spiral nozzles 6, an oil-water mixed liquor outlet 7. The gas inlet pipe 3 is communicated with a gas collector of the coalification furnace, the gas outlet pipe 2 is connected to a rear primary cooler, one end of the annular pipe 5 is connected to a circulating ammonia pipe, and 2-10 spiral nozzles 6 are uniformly distributed along the annular direction. The crude gas flows into indoors via the gas inlet pipe 3 and before the crude gas flows out via the gas outlet pipe by intensively spraying the circulating ammonia water with a gauge pressure of 150-200 kPa via nozzles to quickly lower the temperature of the crude gas, therefore, most of the coal dust, granule, tar or naphthalene etc. are separated from the crude gas and flow out via the oil-gas mixed liquor outlet 7. The separator has the characteristics of good effects on temperature reduction and separation efficiency.
本实用新型公开了一种煤化炉的重要装置,即煤化炉气液分离装置。煤化炉在洁净煤工业中用于进行煤的洁净燃烧作业。本实用新型煤化炉气液分离装置由外壳1、出气管2、荒煤气进气管3、连接筋4、环形喷管5、螺旋喷头6、油水混合液出口7组成。进气管3与煤化炉集气管相通,出气管2与后部初冷器相连,环形管5一端与循环氨水管连接,沿管环形方向均布有2--10个螺旋喷头6。荒煤气经进气管3流入室内,通过出气管2流出前,用表压为150-200kPa的循环氨水通过喷头强烈喷洒,迅速降低荒煤气温度,荒煤气中的大部分煤粉、焦粒、焦油和萘等被分离出来,通过油水混合液出口7流出,具有降温效果好,分离效率高的特点。
