Abstract
The invention discloses a methanol recovery device. The methanol recovery device comprises a reaction kettle and a receiving tank, wherein the reaction kettle is connected with the receiving tank through a pipeline, the pipeline between the reaction kettle and the receiving tank is connected with a first condenser in series, the receiving tank is connected with a second condenser through a pipeline in a cycling manner, the second condenser is connected with a freezing machine through a pipeline, and a layer of molecular sieves is laid in the pipeline in an inlet of the first condenser. When the ambient temperature or reaction temperature is relatively high, methanol in a refining kettle is condensed twice by virtue of two horizontal condensers, and the condensation effect is enhanced by virtue of the freezing machine, so that a purpose of reducing loss of methanol and protecting the living environment can be achieved; and little water in the methanol in the reaction is adsorbed by virtue of the water absorption property of the molecular sieves, and the purity of the recovered methanol is guaranteed.
Description
Technical field
The present invention relates to chemical reaction device field, particularly a kind of methanol recovery device.
Background technology
Chemical reaction is especially in esterification, when needs reclaim methyl alcohol, usually only need directly to access receiving tank to reclaim the methyl alcohol for having reacted in reaction in the exit of rectifying still, because the boiling point of methyl alcohol is too low, be input to through being everlasting in the road of receiving tank and enter into air with regard to components vaporize, thus pollute living environment, and waste ample resources, and reclaim in the lump when there being part water to be entrained in methyl alcohol in course of reaction, the quality reclaiming methyl alcohol can be affected.
Summary of the invention
The present invention is in order to overcome the deficiency of above-mentioned technical problem, and providing a kind of methanol recovery device can solve the problem completely.
The technical scheme solved the problems of the technologies described above is as follows:
A kind of methanol recovery device, comprise reactor and receiving tank, described reactor is connected by pipeline with receiving tank, described reactor is connected in series the first condenser with on the pipeline of receiving tank, described receiving tank is connected by piping loop with the second condenser, the second described condenser connects a refrigerator by pipeline, is covered with one deck molecular sieve in the pipeline at the first described condenser inlet place.
Further, the first described condenser and the second condenser are horizontal condenser.
Structure of the present invention is simple; with low cost; can environment temperature or reaction temperature higher time; methyl alcohol in rectifying still is carried out twice condensation by two horizontal condensers; and strengthen condensation effect by refrigerator, thus reach the object reducing methanol loss, protection living environment, by the water imbibition of molecular sieve; by a small amount of water adsorption be entrained in reaction in methyl alcohol, ensure that the purity reclaiming methyl alcohol.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
In figure: 1 is reactor, 2 is receiving tank, and 3 is pipeline, and 4 is the first condenser, and 5 is the second condenser, and 6 is pipeline, and 7 is pipeline, and 8 is refrigerator, and 9 is molecular sieve.
Detailed description of the invention
A kind of methanol recovery device as shown in Figure 1, comprise reactor 1 and receiving tank 2, described reactor 1 is connected by pipeline 3 with receiving tank 2, described reactor 1 is connected in series the first condenser 4 with on the pipeline 3 of receiving tank 2, described receiving tank 2 and the second condenser 5 are circulated by pipeline 6 and are connected, the second described condenser 5 connects a refrigerator 8 by pipeline 7, is covered with one deck molecular sieve 9 in the pipeline 3 of the first described condenser 4 porch.The first described condenser 4 and the second condenser 5 are horizontal condenser.
Structure of the present invention is simple; with low cost; can environment temperature or reaction temperature higher time; methyl alcohol in rectifying still is carried out twice condensation by two horizontal condensers; and strengthen condensation effect by refrigerator, thus reach the object reducing methanol loss, protection living environment, by the water imbibition of molecular sieve; by a small amount of water adsorption be entrained in reaction in methyl alcohol, ensure that the purity reclaiming methyl alcohol.
Schematically above be described invention of the present invention and embodiment thereof, this description does not have restricted, and also just one of the working of an invention mode of the present invention shown in accompanying drawing, actual structure is not limited thereto.If therefore those of ordinary skill in the art enlightens by it, when not departing from innovation and creation aim of the present invention, designing the frame mode similar to this technology and embodiment without creationary, the protection domain of the present invention's invention all should be belonged to.
