Combined glue spray opening

Abstract

The invention belongs to the field of chemical machines, and relates to a combined glue spray opening. The combined glue spray opening is mounted on a pot body of a condensation pot and comprises a glue spray set pipe and a secondary seam pipe. The glue spray set pipe is mounted on the periphery of the secondary steam pipe in a sleeving pipe, the glue spray set pipe and the secondary steam pipe are arranged obliquely, and an opening of the glue spray opening faces the oblique lower portion. The secondary steam pipe comprises a steam connecting flange and a steam pipe, the steam connecting flange is fixed to an inlet at the top end of the steam pipe, and a mounting blind flange is arranged on the upper portion of the steam pipe. The glue spray set pipe comprises a mounting flange and a gluespray pipe. The mounting flange is fixed to the top end of the glue spray pipe, a connecting pipe is arranged on the glue spray pipe to be connected with a glue inlet flange, and the mounting flangeand the mounting blind flange are fixedly connected. By means of the combined glue spray opening, secondary steam and glue can enter the condensation pot at the same time, the quantity of secondary steam can be reduced, it is guaranteed that the operation temperature of the condensation pot keeps at the proper level, the content of steam in gas exhausted from the condensation pot is reduced, the quantity of circulating cooling water is reduced, and the aims of energy saving and consumption reduction are achieved.

Description

technical field [0001] The invention relates to a combined glue spray port, which belongs to the field of chemical machinery. Background technique [0002] In the process of producing synthetic rubber by solution polymerization, the glue (solvent oil, polymerized product and a small amount of unpolymerized monomer) generated by the polymerization reaction is usually vaporized in the coagulation kettle to remove the solvent in the glue Oil and unpolymerized monomers are separated, and at the same time, the polymerized product (synthetic rubber) is expanded and dispersed into uniformly sized solid colloids in hot water. This process is called coagulation. The condensed water containing colloidal particles is then subjected to subsequent processing processes such as dehydration and drying, and finally produces finished rubber. [0003] Tank-type coagulation includes two stages of gasification and diffusion, usually completed in 2 to 3 coagulation tanks operated in series. The...

Problems solved by technology

In order to improve the gasification effect of the first kettle, it is necessary to increase the amount of secondary steam and increase the operating temperature of the whole kettle. The amount of water vapor in the steamed gas from the first kettle will increase accordingly, and the amount of circulating water consumed by condensation will also increase accordingly. Therefore, the energy consumption of the device is high; the secondary steam enters from the bottom of the kettle and is ejected obliquely upward. When the operation fluctuates, the hot water containing colloidal particles is easy to refill into the steam nozzle, causing blockage and affecting the long-term operation of the equipment.
