The utility model has the advantages of the condensation is effectual, can retrieve in succession the lower gaseous phase organic compound of boiling point, improves recovery efficiency, and the energy consumption is low to it is high to retrieve gained organic compound purity, but the direct cycle uses. It is low that the running cost is synthesized to technology, and operation management is convenient, saving investment just can guarantee operation steady in a long -term, ensures discharge to reach standard, does not produce secondary pollution. Choose for use two kinds of technological match's of freezing condensation and membrane technology to handle, the respective advantage of make full use of.
Description
Technical field
This utility model relates to a kind of VOC and reclaims the VOC recovery gas phase membrane device of gas phase membrane device, particularly low-boiling point gas.
Background technology
The technique using VOC in existing chemical production technical is more, in use part VOC produces and consumes, VOC not only produces huge harm to environmental and human health impacts, and causes the great wasting of resources.
In prior art, VOC uses spray-absorption to process, although the method can guarantee that the operation of process units, but deposits the shortcomings such as later separation energy consumption is high, absorption efficiency is low.The technique using activated carbon adsorption, activated carbon uses and produces the three wastes (discarded activated carbon), and additionally active carbon absorption technology is complicated, automaticity is low, safety is poor.Condensation collecting method, can use condensation to collect to reactor high temperature organic gas, and first with the direct-cooled solidifying condensation of spiral again, this method degassing effect is obvious, easily operate, operating cost low, but to low-boiling point gas poor effect.
Membrane separation process reclaims VOC system generally can remove the VOC of more than 99% from feeding gas.The feature of this system is the concentration concentration independent of feeding gas of non-permeate stream, and this concentration is determined by the pressure and temperature of condenser.Usually using air cooler or air heat exchanger to condense in prior art, condensation effect is poor, the best to the separating effect of low-boiling point gas.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, use fridge that system is condensed, there is provided a kind of high-efficiency low energy consumption to reclaim the device of organic compound, it is achieved the recovery of low boiling organic compound and recycling, realize tail gas qualified discharge simultaneously.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of VOC reclaims gas phase membrane device, including VOC gas phase membrane separator, vacuum pump, air intake pump, air inlet condenser, goes out gas condenser, VOC storage tank, fridge；
Described air intake pump, air inlet condenser, VOC gas phase membrane separator, vacuum pump and go out gas condenser pass sequentially through pipeline connect；Described air inlet condenser is connected with VOC storage tank import respectively with the liquid-phase outlet going out gas condenser, and the gaseous phase outlet going out gas condenser is connected with the air inlet of air inlet condenser by circulation line；The retentate side of described VOC gas phase membrane separator is connected with air vent；Described fridge respectively with air inlet condenser and go out gas condenser and be connected, it is provided that cold.
Preferably, the flow of described air vent is adjustable, is simultaneously provided with on-line monitoring, detects gas, controls running status.
Preferably, air inlet delivery side of pump is provided with Flow-rate adjustment.
Preferably, air inlet condenser and the liquid-phase outlet going out gas condenser are equipped with visor to control the chilled water treating capacity of fridge.
Preferably, VOC tank level is automatically adjusted.
Of the present utility modelBeneficial effect:
The utility model has the advantage of that condensation effect is good, the gas phase organic compound that boiling point is relatively low can be carried out continuously recovery, improving organic efficiency, energy consumption is low, and it is high to reclaim gained organic compound purity, can direct reuse.Process synthesis operating cost is low, convenient operation and management, reduces investment outlay and can guarantee that operation steady in a long-term, it is ensured that qualified discharge, does not produce secondary pollution.The technique selecting refrigerated condensation and two kinds of process matchings of film processes, and makes full use of respective advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-VOC gas phase membrane separator, 2-vacuum pump, 3-air intake pump, 4-air inlet condenser, 5-goes out gas condenser, 6-VOC storage tank, 7-fridge, 8-air vent, 9-visor.
Detailed description of the invention
Referring to the drawings, concrete technical scheme of the present utility model is further described, in order to those skilled in the art is further appreciated by this utility model and does not constitute the restriction to its right.
Referring to the drawings 1, a kind of VOC reclaims gas phase membrane device, including VOC gas phase membrane separator 1, vacuum pump 2, air intake pump 3, air inlet condenser 4, goes out gas condenser 5, VOC storage tank 6, fridge 7；Described air intake pump 3, air inlet condenser 4, VOC gas phase membrane separator 1, vacuum pump 2 and go out gas condenser 5 pass sequentially through pipeline connect；Described air inlet condenser 4 is connected with VOC storage tank 6 import respectively with the liquid-phase outlet going out gas condenser 5, and the gaseous phase outlet going out gas condenser 5 is connected with the air inlet of air inlet condenser 4 by circulation line；The retentate side of described VOC gas phase membrane separator 1 is connected with air vent 8；Described fridge 7 respectively with air inlet condenser 4 and go out gas condenser 5 and be connected, it is provided that cold.
Work process is as follows: first controlling to enter air inlet condenser 4 by Flow-rate adjustment through air intake pump 3 by organic compound, air inlet condenser 4 uses fridge 7 chilled water to cool down.The liquid phase of air inlet condenser 4 condensation enters VOC storage tank 6 through visor 9, is controlled the treating capacity of fridge 7 by the liquid phase flow of visor 9, and in air inlet condenser 4, uncooled gas phase enters VOC gas phase membrane separator 1.
