Embodiment 1

[0028] A kind of process deicing method, comprises the following steps:

[0029] Step one, such as figure 1 As shown, the deicing brine inlet pipe is provided on the upper head 2 of the condenser 1, the deicing brine inlet pipe runs through the upper head 2 of the condenser 1, and the outlet of the deicing brine inlet pipe is located in the condenser 1. The outlet of the deicing brine water inlet pipe is connected with a spiral nozzle 21, the spiral nozzle 21 used in this embodiment is a 316L stainless steel spiral nozzle nozzle, and the model with a spray angle of 120° is selected; and the oil and water are connected at the discharge port of the condenser 1 Splitter.

[0030] Step 2, observe the output of condenser 1 (i.e. the output of vinyl acetylene liquid), when the output of vinyl acetylene liquid becomes smaller, it means that the tubes 11 of condenser 1 are frozen; turn on the spiral nozzle 21. Feed calcium chloride brine with a mass concentration of 10%-20% into the...

Embodiment 2

[0032] The difference between embodiment 2 and embodiment 1 is only that, as attached figure 2 , image 3 As shown, the liquid collection bucket 3 with the top opening is fixed below the condenser 1, and the bottom of the liquid collection bucket 3 is in an inverted cone shape; then a flow guide tube 5 with both ends closed is arranged at the bottom of the liquid collection bucket 3, and the guide tube 5 is used to 4 Connect the top of the diversion cylinder 5 to the bottom of the liquid collection barrel 3; and set a horizontal rotating shaft 51 that is rotatably connected in the diversion cylinder 5, the rotation shaft 51 is a plastic shaft, and the left end of the rotation shaft 51 runs through the diversion cylinder 5, And extend to the outside of the guide tube 5; a number of blades 511 are fixed on the right part of the rotating shaft 51 below the conduit 4.

[0033] A warning mechanism is set on the left side of the guide tube 5, the warning mechanism includes two opp...

Abstract

The present invention belongs to the industrial production technology field of ethylene acetethis acetraphyene reactions, and a process of craftsmanship has been disclosed, including the following steps: step 1, set up ice salt water into the water pipe through the condenser, and make it so that it can makeThe exit of the ice salt water into the water pipe is located in the condenser. The exit of the ice salt water into the water pipe is set with a spiral sprinkler. Step 2, the calcium chloride salt water is passed to the water pipe to the water pipe, so that the calcium chloride salt water can be carried out through the spiral spray head.Enter the column tube of the condenser to achieve ice consumption.When the present invention solves the existing technology, the condenser must stop operation, resulting in low processing efficiency.

Description

technical field [0001] The invention belongs to the industrial production field of acetylene dimerization reaction to generate vinyl acetylene, and in particular relates to a process deicing method. Background technique [0002] In the process of producing chloroprene rubber by calcium carbide method, vinyl acetylene is produced by dimerization of acetylene, and then chloroprene is synthesized. The vinyl acetylene gas generated by the dimerization reaction needs to be condensed with calcium chloride frozen brine as the medium. device to condense into a liquid. Commonly used condensers include a shell and tubes arranged in the shell. The upper end of the shell is provided with an upper head and the lower end is provided with a lower head. When in use, vinyl acetylene gas is passed into the tubes, and the condenser The condensing medium in the tube is used for cooling; since the generated gas contains moisture, the inside of the tube will freeze and cause blockage during the ...
