Abstract
The utility model provides a technical scheme of a methanol low pressure carbonylation reaction device. The methanol low pressure carbonylation reaction device in the scheme comprises a reactor, a flash evaporator, a first circulating pump and a first heat exchanger, wherein, the flash evaporator is connected with the reactor; the flash evaporator is communicated with the first circulating pump; and the first circulating pump is communicated with the first heat exchanger. The utility model is characterized in that the reactor is further communicated with a second circulating pump; the second circulating pump is communicated with a second heat exchanger; the second heat exchanger is communicated with the reaction vessel; in addition, the second circulating pump is communicated with the first heat exchanger. The device ensures that heat produced by the reaction can be brought away in time and smoothly, so as to further provide space for enhancing the load.
Description
Technical field:
The utility model relates to a kind of chemical products reaction device, especially a kind of low-pressure methanol carbonylation reaction device.
Background technology:
In the prior art, technique known is that low-pressure methanol carbonylation reaction device is by single refrigerating unit cycle control, promptly relies on a recycle pump and a scatterer, the heat that produces when taking away reaction; When the production load of reaction unit significantly improved, the circulation of reaction solution increased, and the transmission of reaction solution heat is restricted, and the further raising of producing load has been produced restriction.
Summary of the invention:
The purpose of this utility model, be exactly at the deficiencies in the prior art, and provide a kind of technical scheme of low-pressure methanol carbonylation reaction device, the device of this programme has increased a recycle pump and an interchanger again on original round-robin basis, can in time take away the heat that reaction produces stably, make device can further improve load.
This programme is implemented by following technical measures: a kind of low-pressure methanol carbonylation reaction device, comprise reactor, the flasher that is communicated with reactor, flasher also is communicated with first recycle pump, and first recycle pump is communicated with reactor by first interchanger, and the characteristics of this programme are: reactor also is communicated with second recycle pump, second recycle pump is communicated with second interchanger, second interchanger also is communicated with reactor, and in addition, second recycle pump also is communicated with first interchanger.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing in this scheme, increased by second recycle pump and second interchanger, second recycle pump is communicated with second interchanger, second interchanger is communicated with reactor, can high loading, shift heat stably, provide the space for system further improves load; And second recycle pump also is communicated with first interchanger, is used to regulate the second outlet of circulating pump flow, avoids flow too small, makes the reaction solution reactor that flows backwards back; Simultaneously, when whole device was started working, owing to increased new interchanger, the speed that reaction solution is heated up was accelerated, and has accelerated the carrying out of reaction.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the effect of having a mind to of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure, 1 is second interchanger, and 2 is first interchanger, and 3 is first recycle pump, and 4 is second recycle pump, and 5 is flasher, and 6 is reactor.
Embodiment:
For clearly demonstrating the technical characterstic of this programme,, and in conjunction with the accompanying drawings, this programme is set forth below by an embodiment.
By accompanying drawing as can be seen, the low-pressure methanol carbonylation reaction device of this programme, comprise reactor 6, the flasher 5 that is communicated with reactor 6, flasher 5 also are communicated with first recycle pump 3, first recycle pump 3 is communicated with reactor 6 by first interchanger 2, the characteristics of this programme are: described reactor 6 also is communicated with second recycle pump 4, and second recycle pump 4 is communicated with second interchanger 1, and second interchanger 1 also is communicated with reactor 6, in addition, second recycle pump 4 also is communicated with first interchanger 1.
