Abstract
The invention provides a kind of cellulose ether and produce device for recovering tail gas, it includes device for recovering tail gas (1), low temperature plate washer (2) is installed in device for recovering tail gas, device for recovering tail gas is provided with gas inlet (3), chilled water import (5) and solvent outlet (4) are provided below, top is provided with chilled water outlet (6) and offgas outlet (7), equipped with liquidometer (8) on device for recovering tail gas (1), the solvent recovery recycling that this device can will contain in tail gas, recovery utilization rate reaches more than 99%, cost has been saved in production for cellulose ether, decrease tail gas environment is stained simultaneously.
Description
Technical field
The invention belongs to fine chemistry industry production field, relate to the retracting device of cellulose ether, particularly a kind of cellulose ether produces device for recovering tail gas.
Background technology
Present stage, in the production process of cellulose ether, it is used mostly the lower alcohol such as ethanol or isopropanol as reaction dissolvent, in order to make cellulose ether material can fully react in a kettle., vacuum pump can be used to be extracted out by the air in reactor, thus completely cut off the oxidation reaction of material, and improving the quality of product, these air extracted out can be discharged by exhausting pipeline；Cellulose ether material is also had a little gaseous solvent in recovery or washing process and is discharged by exhausting pipeline, and the tail gas produced in these production processes has multiple chemical substance, has certain pollution to environment, improves again production cost simultaneously.
Summary of the invention
It is an object of the invention to provide a kind of cellulose ether and produce device for recovering tail gas.Solvent recovery in tail gas can be recycled by this device, it is to avoid the tail gas pollution to environment.
The purpose of invention is achieved in that a kind of cellulose ether produces device for recovering tail gas, it includes device for recovering tail gas, low temperature plate washer is installed in device for recovering tail gas, device for recovering tail gas is provided with gas inlet, chilled water import and solvent outlet are provided below, top is provided with chilled water outlet and offgas outlet, equipped with liquidometer on device for recovering tail gas.
The solvent recovery recycling that this device can will contain in tail gas, recovery utilization rate reaches more than 99%, and cost has been saved in the production for cellulose ether, decreases tail gas simultaneously and stains environment.
Accompanying drawing explanation
Accompanying drawing is that a kind of cellulose ether of the present invention produces device for recovering tail gas schematic diagram.
Detailed description of the invention
Accompanying drawing shows that one cellulose ether of the present invention produces device for recovering tail gas, it includes that device for recovering tail gas 1, low temperature plate washer 2, gas inlet 3, solvent outlet 4, chilled water import 5, chilled water outlet 6, offgas outlet 7, liquidometer 8 form, detailed description of the invention:
The tail gas that cellulose ether produces in process of production enters in device for recovering tail gas 1 by gas inlet 3, in chilled water is entered the chuck of device for recovering tail gas 1 by chilled water import 5 and in low temperature plate washer 2, chilled water outlet 6 is arranged on above device for recovering tail gas 1, make chilled water at device for recovering tail gas 1 internal circulation flow, the temperature of device for recovering tail gas 1 can be maintained under certain low temperature state, the solvent in tail gas is made to be become liquid from gaseous state, tail gas is after multiple low temperature plate washer 2, solvent in tail gas can be recycled to bottom device for recovering tail gas 1 effectively, other gas is discharged by offgas outlet 7, after liquidometer 8 shows that recovered solvent reaches certain liquid level, solvent is delivered to production system by solvent outlet 4.
Claims (1)
