Problems solved by technology
Most of the condensers currently used use circulating water as the cooling medium. Because the temperature is too low, benzene will solidify in the condenser and block the distillation pipeline, resulting in excessive pressure in the distillation kettle and causing danger.

The invention discloses a condenser for mono-benzene distillation. The condenser comprises a condensation cylinder, a left tube tank and a right tube tank, wherein the left tube tank and the right tube tank are mounted at both ends of the condensation cylinder; both the left tube tank and the right tube tank are provided with temperature detectors; and an expansion joint is arranged on the body ofthe condensation cylinder. Temperature sensors are respectively arranged on the feeding hole of the left tube tank and the discharge hole of the right tube tank and are used for monitoring feeding and discharge temperatures of mono-benzene distillation, the temperatures are strictly controlled within set ranges, and the consequence that the temperature is g too low, mono-benzene is cooled and condensed on a pipeline, the pipeline is blocked and thus the pressure in the condenser is too large can be avoided; and due to adoption of the expansion joint on the condensation cylinder, the pressurein a bucket can be effectively reduced, the pressure in the cylinder can be released within a short time even if slight blocking pressure is caused, and temperatures can be adjusted and pressure can be balanced conveniently.
Description
technical field [0001] The present invention relates to a condenser for distilling benzene. Background technique [0002] Since 1825, the British scientist Faraday first discovered benzene (Benzene, C 6 h 6 ), distillation has always been an important method to obtain benzene. Because benzene is volatile and has a low melting and boiling point (5.5°C, boiling point 80.1°C), a condenser is an essential device in the process of benzene concentration and distillation. . Most of the condensers currently used use circulating water as the cooling medium. Because the temperature is too low, benzene will solidify in the condenser and block the distillation pipeline, resulting in excessive pressure in the still and causing danger. Therefore, controlling the cooling temperature and adjusting the pressure of the condensing pipe is the most important thing. In view of this, a condenser for benzene distillation is proposed to solve the above-mentioned problems. Contents of the inven...
