Abstract
The utility model discloses a device for collecting tail gases in silica gel synthesis, which comprises a tail gas collecting tank, wherein a tail gas exhaustion pipe is connected onto the tail gas collecting tank, and a spraying device is arranged on the tail gas exhaustion pipe. A certain volume of water is injected into the tail gas collecting tank in advance. During use, the water in the tail gas collecting tank is pumped by a pipeline pump to a sprayer head which is arranged at the upper end of the tail gas exhaustion pipe to be sprayed on exhaust tail gases, and trimethylamine gas is adsorbed by use of water mist, so as to achieve the purpose of ensuring zero discharge of trimethylamine gas and greatly increase the purity of exhaust gases. Besides, only one spraying device is added, so that the device has a simple structure and a low cost.
Description
Technical field
The utility model relates to a kind of gas collector, particularly a kind of gathering-device that is used for the silica gel synthesis tail gas.
Background technology
Organic silicon rubber because can produce low-boiling-point substance and trimethylamine gas in the rubber building-up process, is polluted for fear of environment in process of production, by using gathering-device harmful substance in this tail gas is filtered, and the gas that will handle is again discharged.Tail gas collecting device of the prior art, comprise tail gas condenser, the exhaust collection jar, be communicated with exhaust pipe and tail gas jar on the tail condenser, during work, most of low-boiling-point substance when passing through the condenser of process units is liquefied with low-boiling-point substance and trimethylamine gas, and still being gaseous form, small part low-boiling-point substance and trimethylamine extracted out by vavuum pump, further cooling off the formation liquid state by tail gas condenser the time is received by the exhaust collection jar, because only 24 degrees centigrade of the boiling points of trimethylamine, during discharging, still have a small amount of trimethylamine gas and be discharged in the atmosphere, environment is polluted by exhaust pipe.
The utility model content
Technical problem to be solved in the utility model provides a kind of gathering-device that is used for the silica gel synthesis tail gas, and the tail gas collecting device of this structure can improve the degree of purity of emission gases greatly, and simple in structure, with low cost.
In order to solve the problems of the technologies described above, a kind of gathering-device that is used for the silica gel synthesis tail gas of the utility model comprises the exhaust collection jar, connects exhaust pipe on the exhaust collection jar, and wherein, exhaust pipe is provided with a spray equipment.
Above-mentioned a kind of gathering-device that is used for the silica gel synthesis tail gas, wherein, described spray equipment comprises water pump, water pipe, and the import of described water pipe is communicated with described exhaust collection jar, the outlet of described water pipe is communicated with described exhaust pipe, and described water pump is connected on the described water pipe.
Above-mentioned a kind of gathering-device that is used for the silica gel synthesis tail gas, wherein, the outlet of described water pipe is positioned at described exhaust pipe upper end.
Above-mentioned a kind of gathering-device that is used for the silica gel synthesis tail gas, wherein, the outlet of described water pipe is provided with spray head, and described showerhead bottom surface evenly is provided with a plurality of through holes.
The utility model can be realized following beneficial effect:
1, because exhaust pipe is provided with a spray equipment, earlier to injecting an amount of water in the exhaust collection jar, in use the water in the exhaust collection jar is pumped into the spray head place of exhaust pipe upper end by tubing pump, discharge tail gas is dashed pouring utilize water smoke that trimethylamine gas is adsorbed, thereby reach the purpose of trimethylamine gas zero-emission, improve the degree of purity of emission gases greatly, and the utility model has only added a spray equipment, therefore, simple in structure, with low cost.
2, because spray equipment comprises water pump, water pipe, the spray equipment of this structure is with low cost, simple in structure, and is convenient for changing.
3, because the outlet of water pipe is positioned at described exhaust pipe upper end, can avoid the trimethylamine gas of upper end in the exhaust pipe can't be atomized and be discharged, thereby, gas is purified to greatest extent.
4, because the outlet of described water pipe is provided with spray head, and showerhead bottom surface evenly is provided with a plurality of through holes, during shower water, can make water refinement more, even, thereby, trimethylamine gas is fully adsorbed, further improved adsorption effect of the present utility model.
