Abstract
The utility model discloses a device of vacuum play water foam when reducing polyether production, including vacuum pump and sewage pipe, the outlet pipe that corresponds the vacuum pump on the sewage pipe has hole enlargement portion, the top surface opening of hole enlargement portion, and the play water end of the outlet pipe of vacuum pump inserts in the opening of hole enlargement portion, still is equipped with the defoaming dripper directly over the opening of hole enlargement portion, and defoaming dripper bottom has the liquid outlet. This reduce device of vacuum play water foam during polyether production is safe practical, reduces defoaming agent use amount and defoaming effect good.
Description
The technical field is as follows:
the utility model relates to a chemical industry field particularly is a device of vacuum play water foam when reducing polyether production.
Background art:
at present, inevitable trace material leakage at the water outlet of a vacuum pump in the vacuum-drawing process of polyether production is caused, and the impact force of outlet water entering a sewage pipeline is large due to the fact that the pipeline at the water outlet of the vacuum pump is small, so that a large amount of foam is generated and accumulated at the water outlet, the environment in a workshop is poor, and the requirement of the workshop for 5S cannot be met; if the accumulated foam flows out of the workshop, the influence on the environment is caused, and the foam is eliminated by pouring a defoaming agent into the opening of the pipeline, the foam can be eliminated in a short time, but the consumption of the defoaming agent is large, and the defoaming agent needs to be added frequently.
The utility model has the following contents:
the utility model aims to solve the technical problem that a safe practical is provided, reduce defoaming agent use amount and the effectual device of vacuum play water foam of reduction during polyether production of defoaming.
The technical solution of the utility model is, provide a device of vacuum play water foam when reducing polyether production, including vacuum pump and sewage pipe, the outlet pipe that corresponds the vacuum pump on the sewage pipe has hole enlargement portion, the top surface opening of hole enlargement portion, and the outlet end of the outlet pipe of vacuum pump inserts in the opening of hole enlargement portion, still is equipped with the defoaming dripper directly over the opening of hole enlargement portion, and defoaming dripper bottom has the liquid outlet, is connected with the drain pipe on the liquid outlet downwards, and the drain pipe is near the opening setting of hole enlargement portion, still is equipped with adjustable valve on the drain pipe.
Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: in the existing device, the sewage pipeline is small, so that foam can be continuously generated and is easy to accumulate, and the impact can be reduced and the foam generation can be reduced after the diameter of the sewage pipeline is expanded; the defoaming dropping device with a valve is installed, a dropping liquid port enters a water outlet of the vacuum pump and a water port on the upper part of the sewage discharge pipe, and the valve is opened when foam is generated, so that the flow rate is adjusted and the foam is eliminated.
Preferably, the diameter of the enlarged diameter portion is 1.5 times or more the diameter of the other portion of the sewage pipe.
Preferably, the defoaming dropping liquid device is also provided with a liquid inlet.
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 device for reducing vacuum water outlet foam during polyether production comprises a vacuum pump 1 and a sewage pipe 2, wherein a water inlet of the vacuum pump 1 is connected with a water inlet pipe 3, the sewage pipe 2 is provided with an expanded diameter part 21 corresponding to a water outlet pipe of the vacuum pump, the top surface of the expanded diameter part is opened, a water outlet end of a water outlet pipe 11 of the vacuum pump 1 is inserted into the opening of the expanded diameter part, a defoaming dripper 4 is further arranged right above the opening of the expanded diameter part 21, a liquid outlet is arranged at the bottom of the defoaming dripper 4, a liquid outlet pipe 41 is connected to the liquid outlet in a downward direction, the liquid outlet pipe 41 is arranged close to the opening of the expanded diameter part, an adjustable valve 42 is further arranged on the liquid outlet pipe 41, and the adjustable valve 42 is a ball valve. The diameter of the enlarged diameter part 21 is 1.5 times or more the diameter of the other part of the sewage pipe in order to have good water flow impact resistance. Defoaming drip ware 4 is plastics or steel structure, hangs the mode through the suspender and fixes on the inlet tube of vacuum pump, and the inlet tube level setting of vacuum pump 1 is in the vacuum pump top, and defoaming drip ware 4 shapes are big-end-up's coniform, still is equipped with the inlet on the defoaming drip ware 4, and defoaming drip ware's liquid outlet and drain pipe spiro union or welded fastening, the pipe diameter of drain pipe are 3 mm. This structure is through being done the hole enlargement with the pipe diameter of sewage pipe and vacuum pump junction to reduce the rivers impact and realize subducing of bubble, simultaneously, cooperate the defoaming drip ware to carry out the defoaming, it is effectual.
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.
