Abstract
The utility model discloses a device for optimizing flushing fluid of a circulating pump mechanical seal, which comprises the circulating pump mechanical seal connected with a first pipe of a system and connected with a pump mechanical seal flushing fluid pipe at the same time; a first ball valve is arranged on the pump mechanical seal flushing fluid pipe; the pump mechanical seal flushing fluid pipe is connected with a dilute acetic acid pipeline through a second pipeline; a second ball valve is arranged on the second pipeline; a third ball valve is arranged on the dilute acetic acid pipeline. The device has the advantages that first, the normal operation and the service life of the circulating pump mechanical seal are ensured effectively; second, the working station operation influenced by reaction liquid component change due to the water content increase caused by that desalted water enters into the system is avoided, third, energy consumption in moisture removal in the follow-up rectification process is reduced, and steam is reduced. The device has significance in reducing water content in the system in the process of low-pressure liquid-phase methanol oxo-synthesis acetic acid and reducing the energy consumption.
Description
Technical field
The utility model relates to the optimization of chemical process field, is specially a kind of device of optimizing recycle pump machine envelope washing solution.
Background technique
In the acetic acid synthesized process of low-pressure methanol liquid phase carbonyl, reaction liquid is used through the recycle pump delivery cycle, and in order to guarantee the normal operation of recycle pump machine envelope, design adopts demineralized water as machine envelope washing solution, the machine envelope to be carried out entering system after Cooling and Lubricator.Due to reaction liquid moisture requirement in the acetic acid building-up process approximately 12%, along with constantly adding of recycle pump machine envelope washing solution, reaction liquid moisture progressively raises, and causes the reaction liquid change of component to cause fluctuation of operating conditions.Also cause simultaneously postorder rectification working process moisture removal energy consumption to increase, consume a large amount of steam.
Therefore, providing a kind of normal operation of recycle pump machine envelope that namely can effectively guarantee, can avoid again the optimization device of the recycle pump machine envelope washing solution of the rising of reaction liquid moisture content, change of component, energy consumption increase simultaneously, has been a problem of needing solution badly.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of normal operation of recycle pump machine envelope that namely can effectively guarantee, can avoid again the device of the optimization recycle pump machine envelope washing solution of the rising of reaction liquid moisture content, change of component, energy consumption increase simultaneously.
The purpose of this utility model is achieved in that
A kind of device of optimizing recycle pump machine envelope washing solution, comprise recycle pump machine envelope 2, recycle pump machine envelope 2 connects the first pipeline 1 of the system that enters, recycle pump machine envelope 2 connects pump machine envelope flushing-liquid pipe 3 simultaneously, on pump machine envelope flushing-liquid pipe 3, be provided with the first ball valve 4, it is characterized in that: described pump machine envelope flushing-liquid pipe 3 is connected with spirit of vinegar pipeline 7 by second pipe 5;
On described second pipe 5, be provided with the second ball valve 6, on spirit of vinegar pipeline 7, be provided with the 3rd ball valve 8.
Positive beneficial effect:The utility model, on the basis of the acetic acid synthesized technological design of former methyl alcohol low pressure liquid phase carbonyl, has provided a kind of optimization device that reduces system water content.Solved as ensureing that the demineralized water washing solution that the normal operation of recycle pump machine envelope adds causes the problem that in system, water content raises, and produces following technique effect: 1, effectively guarantee the normal operation of recycle pump machine envelope and working life; 2, avoided demineralized water to carry out the water content rising that system causes, the fluid component variable effect operating mode that induces reaction operation; 3, reduce the energy consumption that postorder rectification working process moisture content removes increase, saved steam; This to water content in the acetic acid synthesized technique minimizing of low-pressure methanol liquid phase carbonyl system, to reduce energy consumption significant.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, be: the first pipeline 1, recycle pump machine envelope 2, pump machine envelope cleaning hose 3, the first ball valve 4, second pipe 5, the second ball valve 6, spirit of vinegar pipeline 7, the 3rd ball valve 8.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, a kind of device of optimizing recycle pump machine envelope washing solution, comprise recycle pump machine envelope 2, recycle pump machine envelope 2 connects the first pipeline 1 of the system that enters, recycle pump machine envelope 2 connects pump machine envelope flushing-liquid pipe 3 simultaneously, on pump machine envelope flushing-liquid pipe 3, be provided with the first ball valve 4, described pump machine envelope flushing-liquid pipe 3 is connected with spirit of vinegar pipeline 7 by second pipe 5;
On described second pipe 5, be provided with the second ball valve 6, on spirit of vinegar pipeline 7, be provided with the 3rd ball valve 8.
Embodiment 1
On 200,000 tons of acetic acid plants of certain gasification plant, change by the utility model, to by ball valve, be controlled by the spirit of vinegar from the spirit of vinegar pipeline, through second pipe, recycle pump machine envelope is carried out to Cooling and Lubricator, close simultaneously the first ball valve on former pump machine envelope washing solution pipeline, namely guaranteed the normal operation of recycle pump machine envelope, the system water content of also having avoided simultaneously former design China and foreign countries to add demineralized water to rinse recycle pump machine envelope and having caused raises, thereby induce reaction fluid component variable effect operating mode, increase simultaneously the problem of postorder product purification energy consumption.
The utility model 1, effectively guarantee the normal operation of recycle pump machine envelope and working life; 2, avoided demineralized water to carry out the water content rising that system causes, the fluid component variable effect operating mode that induces reaction operation; 3, reduce the energy consumption that postorder rectification working process moisture content removes increase, saved steam; This to water content in the acetic acid synthesized technique minimizing of low-pressure methanol liquid phase carbonyl system, to reduce energy consumption significant.
Above embodiment is only be used to illustrating preferred implementation of the present utility model; but the utility model is not limited to above-mentioned mode of execution; in the ken that described field those of ordinary skill possesses; it any modification of doing within spirit of the present utility model and principle, is equal to and substitutes and improvement etc., within all should be encompassed in the technological scheme scope that the utility model asks for protection.
