Novel petroleum ether extraction and separation device

Abstract

The invention discloses a novel petroleum ether extraction and separation device which comprises an extraction tank body, wherein a sealing cover is arranged at the upper end of the extraction tank body; an extraction material inlet, an extracting agent inlet, an emptying valve and a motor are arranged on the sealing cover; the output shaft of the motor penetrates into the extraction tank body and is connected with a stirring device; an outlet of the extraction tank body is connected with a refining tower through a liquid discharging pipe; the exterior of the refining tower is connected with a hydrogenation cylinder; a heating rod is arranged inside the refining tower; a condensing pipe is arranged at the top of the refining tower; the condensing pipe is connected with a collector; the extraction material inlet and the extracting agent inlet are respectively connected with an extraction material pipe and an extracting agent pipe; a mass flowmeter and an electromagnetic valve are arranged at each of one end, which is close to the extraction material inlet, of the extraction material pipe and one end, which is close to the extracting agent inlet, of the extracting agent pipe; a controller and a display screen are further arranged on the sealing cover; the mass flowmeters, the controller and the electromagnetic valves are electrically connected in sequence. According to the novel petroleum ether extraction and separation device, a worker can add a fixed amount of an extraction material and a fixed amount of an extracting agent into the extraction tank body conveniently.

Description

technical field [0001] The invention relates to the technical field of petrochemical equipment, in particular to a novel petroleum ether extraction and separation device. Background technique [0002] With the development of the national economy and the aggravation of environmental pollution, the country's requirements for the quality of petroleum hydrocarbons are gradually increasing. Traditional petroleum ether has strong odor, wide distillation range and high impurity content, which no longer meets the national environmental protection requirements. Petroleum ether extraction and separation devices that can improve the quality of petroleum ether already exist in the prior art, such as the petroleum ether extraction and separation device disclosed in CN 205740906 U. This invention is provided with a temperature sensor on the right side of the middle part of the sealing cover, so that during the production process By adjusting the temperature of the extraction tank in real...
