Abstract
The utility model relates to a methanol recovery device of an esterification reaction kettle, particularly relates to the resource recycling field, and aims to solve the technical problem of methanol waste through providing a methanol recovery device of an esterification reaction kettle. The methanol recovery device comprises a condenser, a reaction kettle, an evaporating pipe and a return conduit, wherein the condenser is fixed at the side upper part of the reaction kettle, the top of the reaction kettle is connected to the top of the condenser through the evaporating pipe; the bottom of the reaction kettle is connected at the bottom of the condenser through the return conduit; a liquid storage tank is connected on the return conduit in series; a valve is connected between the liquid storage tank and the reaction kettle in series; and the liquid storage tank is used for reclaiming the evaporative methanol after the reaction finishes, so that the resource waste and the environmental pollution are reduced.
Description
Technical field
The utility model relates to a kind of reaction kettle of the esterification Methanol Recovery device, particularly the recycling field of resource.
Background technology
Along with the continuous progress of society and the continuous development of science and technology, people more and more are concerned about the earth that we depend on for existence now, and save energy has far reaching significance to we mankind's development.When finishing, traditional esterification need clean reactor, and because the effect of waste heat, a part of methyl alcohol is evaporated and enters condenser in the reactor, enter reactor by return line again, this part methyl alcohol and washings together are excluded wastewater disposal basin, have not only wasted resource, also pollute.
The utility model content
The technical problems to be solved in the utility model provides a kind of reaction kettle of the esterification Methanol Recovery device that can reduce the methyl alcohol waste.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of reaction kettle of the esterification Methanol Recovery device, comprise condenser, reactor, generating tube and return line, described condenser is fixed on the side top of reactor, the top of described reactor and condenser is connected by generating tube, the bottom of reactor and condenser is connected by return line, its innovative point is: be in series with container for storing liquid on described return line, be serially connected with valve between described container for storing liquid and the reactor, the bottom of described container for storing liquid also is equipped with valve and is connected with the methyl alcohol holding tank by pipeline.
Advantage of the present utility model is: by the container for storing liquid of condenser below, reclaim the methyl alcohol that reaction finishes the back evaporation, reduce the wasting of resources and reduce environmental pollution.
Description of drawings
Figure is a reaction kettle of the esterification Methanol Recovery apparatus structure synoptic diagram of the present utility model.
Embodiment
As shown in the figure, comprise reactor 1, condenser 2, generating tube 3 and return line 4, the two ends of described generating tube 3 are connected with the top of reactor 1 with condenser 2 respectively, the bottom of described reactor 1 and condenser 2 is connected by return line 4, on described return line 4, be in series with container for storing liquid 5, and also be serially connected with valve 6 on the return line 4 between described container for storing liquid 5 and the reactor 1, the bottom of described container for storing liquid 5 also is equipped with another valve 7 and is connected with methyl alcohol holding tank 8 by pipeline.
During work, open valve 6, valve-off 7, methyl alcohol in the reactor 1 is evaporated, enter condenser 2 coolings by generating tube 3, enter reactor 1 by return line 4 again, so circulation, when reaction finishes, valve-off 6,7, because the temperature in the reactor 1 is higher, still have part methyl alcohol to be evaporated and enter condenser 2, be cooled to methanol liquid by condenser 2 and flow into container for storing liquid 5 storages, open valve 6 when treating to carry out esterification once more again, allow this part methyl alcohol enter reactor 1 and participate in reaction, also can this part Methanol Recovery be stored to methyl alcohol holding tank 8 by Open valve 7.
