Description

Methanol rectification structure with recovery function

Technical Field

The utility model relates to a methyl alcohol rectification field particularly, relates to a methyl alcohol rectification structure with retrieve function.

Background

The methanol rectifying device is generally divided into two areas, wherein one area is a large equipment area of the rectifying tower, and the other area is a layered framework structure used for storing smaller equipment such as pumps, heat exchangers and the like. The heat exchanger is typically located at the upper level of the structure. The structure is provided with a downpipe for drainage in rainy days. If the upper heat exchanger takes place the methyl alcohol and leaks, the methyl alcohol of leaking to ground can flow to ground through the downpipe on the platform, leads to the trickling of methyl alcohol to cause the pollution of environment, brings safe risk simultaneously.

The utility model discloses a main aim at overcomes prior art's is not enough, provides a methyl alcohol rectification structure with retrieve function, can retrieve the methyl alcohol of leaking.

In order to achieve the above object, the utility model adopts the following technical scheme:

a methanol rectification structure with a recovery function comprises a structure frame body, a downpipe arranged on the structure frame body, a collecting tank arranged at the bottom end of the downpipe, a recovery pipeline communicated with the bottom of the collecting tank and a methanol underground groove arranged at one end, far away from the collecting tank, of the recovery pipeline.

Preferably, the rainwater collecting device further comprises a rainwater pipeline communicated with the bottom end of the collecting tank, and the recovery pipeline is communicated with a first switching valve; and the rainwater pipeline is communicated with a second switching valve.

Preferably, a liquid passing pump is arranged at the notch position of the methanol underground tank and connected with a crude methanol tank through a pipeline.

Preferably, the top ends of the collecting tank and the methanol underground tank are provided with top covers.

The utility model discloses following beneficial effect has: the leaked methanol is collected through the sewer pipe, so that the environmental pollution caused by the flowing of the methanol is reduced.

Wherein the figures include the following reference numerals: 1. a structure frame body; 2. a first magnetic drive pump; 3. a pipeline; 4. a methanol heat exchanger; 5. a methanol rectifying tower; 6. a downpipe; 7. a collection tank; 8. a recovery pipeline; 9. a first switching valve; 10. a rainwater pipeline; 11. a second switching valve; 13. a liquid passing pump; 14 crude methanol tank.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example (b): a methanol rectification structure with a recovery function is disclosed, and is shown in figure 1, and comprises a structure frame body 1, a first magnetic pump 2 arranged at the bottom end of the structure frame body 1, a pipeline 3 communicated with the first magnetic pump 2, a methanol heat exchanger 4 arranged on the structure frame body 1, a methanol rectification tower 5 communicated with the methanol heat exchanger 4, a downpipe 6 arranged on the structure frame body 1, a collecting tank 7 arranged at the bottom end of the downpipe 6, a recovery pipeline 8 communicated with the bottom of the collecting tank 7, a first switching valve 9 arranged on the recovery pipeline 8, a rainwater pipeline 10 communicated with the bottom end of the collecting tank 7, a second switching valve 11 communicated with the rainwater pipeline 10, a methanol underground tank 12 arranged at one end of the recovery pipeline 8 far away from the collecting tank 7, a liquid passing pump 13 arranged at the notch of the methanol underground tank 12 and a crude methanol tank 14 communicated with the liquid passing pump 13.

The structure frame body 1 comprises supporting legs and a supporting plate fixed at the top ends of the supporting legs, and the methanol heat exchanger 4 is placed on the supporting plate. The surface of the supporting plate is an inclined plane, and the top end of the downpipe 6 is communicated with the lowest position of the inclined plane of the supporting plate, so that liquid on the supporting plate can flow into the downpipe 6.

The collecting pit 7 is piled up by cement and forms, and the inclined plane is piled up into to the bottom of collecting pit 7, and recovery pipeline 8 and rainwater pipeline 10 all communicate in the extreme lower position department on inclined plane. In order to reduce the pollution of the environment and the harm to surrounding workers caused by the volatilization of the methanol, the top ends of the collection tank 7 and the methanol underground tank 12 are provided with top covers, so that the overflow of the volatilized methanol is reduced.

When methanol leaks, the methanol flows into the downpipe 6 along the inclined surface of the supporting plate and enters the collecting tank 7 along the downpipe 6, at this time, the first switching valve 9 is opened and the second switching valve 11 is closed, the methanol is discharged into the methanol underground tank 12, and then the methanol is discharged into the crude methanol tank 14 through the liquid passing pump 13 to be collected.

In rainy day, rainwater can flow into the downpipe 6 along the inclined plane of the supporting plate and enter the collecting tank 7 along the downpipe 6, at the moment, the first switching valve 9 is closed and the second switching valve 11 is collected, and the rainwater is collected through the rainwater pipeline 10.
