Abstract
The utility model discloses a device for processing hydrogen peroxide oxidation tail gas. The device for processing the hydrogen peroxide oxidation tail gas comprises a membrane filter, a tank body is arranged outside the membrane filter, a tail gas inlet is arranged in the left side of the lower portion of the tank body, a tail gas outlet is arranged in the upper portion of the tank body, and liquid drops in filtering gas state are caught and collected. According to the device for processing the hydrogen peroxide oxidation tail gas, the membrane filter is mounted in an oxidation tail gas separator arranged in front of an original device for processing the hydrogen peroxide oxidation tail gas, and the membrane filter is fixedly mounted at the lower end of an outlet of the oxidation tail gas separator. Through the method, liquid aromatic hydrocarbon in the tail gas is filtered out, carbon-fiber adsorption effect of a tail gas unit is enabled to be better, regeneration time and replacement time are prolonged, running fee is reduced, and site environment is protected.
Description
Technical field
The utility model relates to hydrogen peroxide oxidation vent gas treatment field, particularly relates to a kind ofly being used for the hydrogen peroxide oxidation exhaust gas processing device with film filter.
Background technology
It is relevant with the consumption reduction of environmental protection and device that requirement is reclaimed in the purification of aromatic hydrocarbons in the oxydol production apparatus emptying end gas, domestic oxydol production apparatus great majority adopt the method for condensation sedimentation absorption to reclaim to the aromatic hydrocarbons of emptying end gas, but after the condensation (10～20 ℃), arene content reaches 20～30g/m in the tail gas
3Reclaim this part aromatic hydrocarbons and will reduce the hydrogen peroxide production cost on the one hand, also satisfy on the other hand environmental requirement.
Because the liquid-drop diameter of the liquid aromatic hydrocarbons of carrying secretly is very little, common 1～10um, with common settling tank very obstinate, follow-up by the aromatic hydrocarbons in tail gas unit (water at low temperature condensation PAN-ACF method) the recovery oxidized tail gas, except will adsorbing gas aromatic hydrocarbons wherein, also to adsorb the aromatic hydrocarbons that wherein exists with the droplet form, this has increased the load of adsorbent equipment greatly, so the PAN-ACF effect increases the obvious shortcoming that descends with increase and the regeneration frequency of service time, need periodic replacement, operating cost is relatively high.
The utility model content
The technical problem that the utility model mainly solves provides a kind of for the hydrogen peroxide oxidation exhaust gas processing device, by in the oxidized tail gas separator, increasing film filter, can filter out the liquid aromatic hydrocarbons in the tail gas, so that tail gas unit PAN-ACF better effects if, regeneration and replacing time lengthening, reduce operating cost, protected site environment.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of for hydrogen peroxide oxidation tail gas high efficiente callback device, comprise: the film filter outside is a tank body, limit, tank body lower part left side is provided with gas inlet, the tail gas outlet is arranged at top, capture and filter drop in the gaseous state, the present invention installs film filter in the oxidized tail gas separator before original hydrogen peroxide oxidation exhaust gas processing device, and film filter is fixedly mounted on oxidized tail gas separator outlet lower end.By the way, can filter out liquid aromatic hydrocarbons in the tail gas.
In preferred embodiment of the utility model, described film filter comprises filter course, and described filter course is fixed on the film filter cavity inner wall.
In preferred embodiment of the utility model, described filter course is the organic film rete, one side of described organic film is provided with the supporting network that is fixed on the film filter cavity inner wall, and organic film pastes on supporting network, and by supporting network organic film is positioned in the film filter cavity.
The beneficial effects of the utility model are: the utility model is used for the hydrogen peroxide oxidation exhaust gas processing device by increasing film filter at the oxidized tail gas separator; can filter out the liquid aromatic hydrocarbons in the tail gas; so that tail gas unit PAN-ACF better effects if; regeneration and replacing time lengthening; reduce operating cost, protected site environment.
