The vapor phase heating medium system in the polyester production can effectively separate light components and recycle the light components.
Description
The technical field is as follows:
the utility model relates to a polyester production field, concretely relates to vapour phase heat medium system in polyester production.
Background art:
in the production of polyester, the gas-phase heating medium is degassed and then directly enters the collecting tank, and light components are difficult to separate due to the low temperature of the collecting tank.
The utility model has the following contents:
the utility model aims to solve the technical problem of providing a vapor phase heat medium system in polyester production that can effectively separate the light component and recycle.
The technical solution of the utility model is, provide a vapor phase heat medium system in polyester production, including the vapor phase heat medium evaporimeter, the vapor phase export of vapor phase heat medium evaporimeter passes through the vapor phase heat medium pipe connection with the user, the liquid phase heat medium of condensation passes through the liquid phase access connection of first circulating pipe with the vapor phase heat medium evaporimeter after the user uses, be equipped with first circulating pump on the first circulating pipe, the vapor phase heat medium after the user uses passes through the entry linkage of vapor phase discharge pipe and vapour and liquid separator, vapour and liquid separator's liquid phase exit linkage liquid phase heat medium collection tank, liquid phase heat medium collection pipe passes through the liquid phase heat medium access connection of second circulating pipe with the vapor phase heat medium evaporimeter, be equipped with the second circulating pump on the second circulating pipe, vapour and liquid separator's vapor phase export and cooler access connection, the cooler export is connected with the vapor phase collection tank.
Preferably, the vapor outlet of the vapor-liquid separator is connected to the cooler inlet via a connecting pipe.
Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: and the vapor-phase discharge pipe is connected with a vapor-liquid separator, so that light components are separated and do not enter the liquid-phase collecting tank, and the light components are effectively removed and then recycled to the vapor-phase heat medium generator.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
the invention will be further explained with reference to the drawings and the detailed description below:
as shown in fig. 1, a vapor phase heat medium system in polyester production comprises a vapor phase heat medium evaporator 1, a vapor phase outlet of the vapor phase heat medium evaporator 1 is connected with a user 2 through a vapor phase heat medium pipe 3, a liquid phase heat medium condensed after use by the user is connected with a liquid phase inlet of the vapor phase heat medium evaporator 1 through a first circulation pipe 4, the first circulation pipe 4 is provided with a first circulation pump 5, the vapor phase heat medium used by the user is connected with an inlet of a vapor-liquid separator 7 through a vapor phase discharge pipe 6, a liquid phase outlet of the vapor-liquid separator 7 is connected with a liquid phase heat medium collection tank 8, the liquid phase heat medium collection tank 8 is connected with the liquid phase heat medium inlet of the vapor phase heat medium evaporator 1 through a second circulation pipe 9, the second circulation pipe 9 is provided with a second circulation pump 10, the vapor phase outlet of the vapor phase heat medium 7 is connected with an inlet of a cooler 11 through a connection pipe, an outlet of the, the cooled light components also enter a vapor phase collecting tank, then vapor phase heating medium is discharged through a vapor phase outlet of the vapor phase separating tank, flows down the light components and can be discharged through a discharge pipe of the vapor phase collecting tank, and the discharge pipe is provided with a switch valve. Of course, valves such as regulating valves or switch valves can be additionally arranged on the related pipelines according to actual needs. The users in the system refer to equipment such as a reaction kettle, an injection pump and the like, in the embodiment, the heating medium is biphenyl, the biphenyl is cracked to generate heavy components and light components, the light components are low in boiling point and corrosive, if the biphenyl is not directly recycled, the biphenyl easily corrodes a pipeline, and the heating temperature is influenced.
And the vapor-phase discharge pipe is connected with a vapor-liquid separator, so that light components are separated and do not enter the liquid-phase collecting tank, and the light components are effectively removed and then recycled to the vapor-phase heat medium generator. All the devices in the system are common devices in the field, and are considered to be the prior art without structural changes.
The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
