A kind of impure steam collection and condensation equipment

Abstract

The invention discloses impure steam collection and condensation equipment, which comprises a gas-liquid separator, a desuperheater, an impure steam washer and a circulating pump which are successively connected. A gas-liquid mixture containing magnesium chloride bittern and impure steam passes through the gas-liquid separator to separate impure steam and magnesium chloride bittern. Impure steam passes through the desuperheater for reduction of temperature so as to form desuperheated steam. Through washing by the impure steam washer under the action of the circulating pump, hydrogen chloride is absorbed and then discharged. The desuperheater comprises a Venturi tube connected with the gas-liquid separator, a nozzle arranged at the throat of the Venturi tube, a sleeve arranged at the otherend of the Venturi tube, a temperature sensor arranged at the sleeve and a control device. The sleeve is connected with the impure steam washer. The desuperheater sprays desuperheating water to reducetemperature of the impure steam. As the impure steam collection and condensation equipment is provided with the desuperheater, cooling treatment is firstly carried out before washing and absorption.Thereby, damage of high temperature steam to pipelines or equipment is reduced. In addition, the cooling effect is good, and retardance is small.

Description

technical field [0001] The invention relates to the technical field of resource utilization of chemical products, in particular to a device for collecting and condensing impure steam. Background technique [0002] Qinghai is a resource-rich province with a wide variety of natural resources, among which the representative resources are salt lake resources. Chaerhan Salt Lake is the largest chloride-type potassium-sodium-magnesium salt deposit in China. It has large reserves, high grade, complete types, and relatively concentrated distribution. It has the characteristics of good resource combination, including 55.5 billion tons of sodium chloride reserves, 150 million tons of potassium chloride reserves, 4.9 billion tons of magnesium chloride, and rich national strategic resources such as lithium, rubidium, and cesium. It is the salt lake with the most development value in China. , with a potential economic value of more than 12 trillion yuan. [0003] Salt lake resources mai...
