Abstract
The utility model discloses an etherification device, which comprises a halogenated hydrocarbon storage tank, a head tank, an etherification reactor and a condenser. A circulating pump is arranged between the halogenated hydrocarbon storage tank and the head tank, and a rotary valve is arranged between the head tank and the etherification reactor. The etherification device has the advantages that a recycling device is arranged at the upper end of a metering tank so that volatilization of volatile halogenated hydrocarbon and waste are reduced, environmental odor is decreased while operation safety is guaranteed.
Description
Technical field
The utility model relates to a kind of reaction unit, and specifically a kind of etherification reaction device belongs to the chemical industry equipment field.
Background technology
At present, in China's Chemical Manufacture etherification reaction, used alkenyl halide is volatile, penetrating odor is arranged, density is little, usually generally use generally is after the stainless steel head tank measures, rise to certain altitude and change measuring tank over to, after the emptying of high-altitude, be added drop-wise to and participate in reaction in the etherificate still.Yet this method is because the high volatility of raw material alkenyl halide, thereby causes the waste that produces and the contamination phenomenon of environment, and alkenyl halide belongs to inflammable thing simultaneously, has very big potential safety hazard.
The utility model content
In order to address the above problem, the utility model has designed a kind of etherification reaction device, and this device can solve the volatile phenomenon of alkenyl halide effectively, reduce the waste and and the handling safety of raw material.
The technical solution of the utility model is:
A kind of etherification reaction device comprises: halogenated hydrocarbons storage tank, head tank, etherifying reactor and the condenser of Lian Tonging successively; Be provided with circulating pump between described halogenated hydrocarbons storage tank and the described head tank, be provided with rotary valve between described head tank and the described etherifying reactor;
Described condenser is positioned on the described etherifying reactor, and described condenser is provided with exhausting pipeline, and described exhausting pipeline is provided with exhaust-valve;
Be communicated with by recovery channel between described halogenated hydrocarbons storage tank and the head tank, described recovery channel is provided with pressure limiting valve.
Etherification reaction liquid is forced into head tank through circulating pump, by rotary valve control rate of addition, the liquid that volatilizees in the head tank is back to the halogenated hydrocarbons storage tank through recovery channel, realize emptying at halogenated hydrocarbons storage tank place, when pressure is big, by the pressure limiting valve emptying, the effect that the exhausting pipeline that is provided with on the condenser can prevent to dash material and play condensation recovery and emptying is to keep etherifying reactor internal pressure balance.
Advantage of the present utility model is: the volatilization of volatile halogenated hydrocarbons is reduced for retracting device in the measuring tank upper end, cuts the waste, and reduces the environment smell, handling safety.
The utility model is described in further detail with enforcement below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Among the figure: 1-halogenated hydrocarbons storage tank, 2-circulating pump, 3-head tank, 4-rotary valve, 5-etherifying reactor, 6-recovery channel, 7-condenser, 8-exhausting pipeline, 9-exhaust-valve, 10-pressure limiting valve.
The specific embodiment
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
Embodiment 1
As shown in Figure 1, a kind of etherification reaction device comprises: the halogenated hydrocarbons storage tank 1 of Lian Tonging, head tank 3, etherifying reactor 5 and condenser 7 successively; Be provided with circulating pump 2 between described halogenated hydrocarbons storage tank 1 and the described head tank 3, be provided with rotary valve 4 between described head tank 3 and the described etherifying reactor 5;
Described condenser 7 is positioned on the described etherifying reactor 5, and described condenser 7 is provided with exhausting pipeline 8, and described exhausting pipeline 8 is provided with exhaust-valve 9;
Be communicated with by recovery channel 6 between described halogenated hydrocarbons storage tank 1 and the head tank 3, described recovery channel 6 is provided with pressure limiting valve 10.
Etherification reaction liquid is forced into head tank 3 through circulating pump 2, by rotary valve 4 control rate of addition, the liquid of volatilization is back to halogenated hydrocarbons storage tank 1 through recovery channel 6 in the head tank 3, realize emptying at halogenated hydrocarbons storage tank 1 place, when pressure is big, by pressure limiting valve 10 emptyings, the effect that the exhausting pipeline 8 that is provided with on the condenser 7 can prevent to dash material and play condensation recovery and emptying is to keep etherifying reactor 5 internal pressure balances.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
