Abstract
The utility model relates to a steam stripping separation device for waste water generated in polyester process. The steam stripping separation device comprises an aldehyde-contained waste water tank and a steam stripping tower, wherein the aldehyde-container waste water tank is communicated with a water inlet of the steam stripping tower by a water inlet pipe, a water inlet pump is arranged on the water inlet pipe, a water outlet of the steam stripping tower is communicated with a waste water tank by a water outlet pipe, a water outlet pump is arranged on the water outlet pipe, the steam stripping tower is also provided with a direct steam inlet pipe and an indirect steam inlet pipe, which are both connected with a steam generator, and a gas outlet of the steam stripping tower is connected with a boiler by a gas outlet pipe. The steam stripping separation device is suitable for processing the aldehyde-container waste water generated in the polyester production process, so that the aldehyde-contained waste water can not pollute environment and can be recycled, and the environmental protection is realized.
Description
Technical field
The utility model relates to a kind of polyester process waste water stripping separating and treating apparatus.
Background technology
In polyester production process, can produce some aldehyde-containing sewages, this kind aldehyde-containing sewage has irritating smell, is that country prohibites direct discharging.Because receive factors such as technical limitation, handling these aldehyde-containing sewages at present all is to wait it to volatilize naturally, the irritant gas that evaporates is sent into the boiler chimney discharging, waste water send outer the processing.This kind mode not only wastes time and energy, and not environmental protection.
The utility model content
The utility model technical problem to be solved is: provide a kind of simple to operate, and the polyester process waste water stripping separating and treating apparatus of environmental protection.
For addressing the above problem; The technical scheme that the utility model adopts is: polyester process waste water stripping separating and treating apparatus; Comprise aldehyde-containing sewage pond, stripping tower; Said aldehyde-containing sewage pond is connected with the water inlet of stripping tower through water inlet pipe and water inlet pipe is provided with intake pump, and the water outlet of stripping tower is irritated through rising pipe and waste water and is connected and rising pipe is provided with out water pump, also is provided with open steam on the stripping tower and goes into pipe and go into to manage with indirect steam; Open steam is gone into pipe and is gone into the Guan Junyu vapour generator with indirect steam and be connected, and the air outlet of stripping tower is connected with boiler through escape pipe.
Also be provided with plate-type heat exchanger on the described rising pipe, the heat-exchange end of plate-type heat exchanger connects water coolant.
The beneficial effect of the utility model is: above-mentioned polyester process waste water stripping separating and treating apparatus; It is simple in structure, easy to use, and after the wherethrough reason, the aldehyde-containing sewage that in polyester production process, produces does not only pollute the environment; Realize environmental protection, and can also obtain recycling.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model polyester process waste water stripping separating and treating apparatus;
Among the figure: 1, aldehyde-containing sewage pond, 2, stripping tower, 3, plate-type heat exchanger, 4, water inlet pipe, 5, intake pump, 6, rising pipe, 7, open steam goes into pipe, 8, indirect steam goes into pipe, 9, vapour generator, 10, escape pipe, 11, boiler, 12, go out water pump.
Embodiment
Through specific embodiment the utility model polyester process waste water stripping separating and treating apparatus is done further to describe in detail below.
As shown in Figure 1; Polyester process waste water stripping separating and treating apparatus; Comprise aldehyde-containing sewage pond 1, stripping tower 2, said aldehyde-containing sewage pond 1 is connected with the water inlet of stripping tower 2 through water inlet pipe 4 and water inlet pipe 4 is provided with intake pump 5, and the waste water filling is connected and rising pipe 6 is provided with out water pump 12 through rising pipe 6 for the water outlet of stripping tower 2; Also be provided with plate-type heat exchanger 3 on the described rising pipe 6, the heat-exchange end of plate-type heat exchanger 3 connects water coolant.Also be provided with open steam on the stripping tower 2 and go into pipe 7 and go into pipe 8 with indirect steam, open steam is gone into pipe 7 and is gone into to manage 8 with indirect steam and all be connected with vapour generator 9, and the air outlet of stripping tower 2 is connected with boiler 11 through escape pipe 10.
The principle of work of the utility model is: the aldehyde-containing sewage in the aldehyde-containing sewage pond 1 gets into the stripping tower 2 through the water inlet of water inlet pipe 4 from stripping tower 2 under the effect of intake pump 5; Vapour generator 9 produces steam and goes into pipe 7 through open steam and go in the pipe 8 entering stripping towers 2 with indirect steam; Under the effect of steam; Gaseous aldehyde in the aldehyde-containing sewage is separated and sends into behind escape pipe 10 from the air outlet of stripping tower 2 in the boiler 11 and burn; Only produce carbonic acid gas and water after the burning, thereby can not produce obnoxious flavour and contaminate environment.Waste water after stripping tower 2 is handled is going out under the effect of water pump 12 through rising pipe 6 to flow into during waste water irritate, and after the heat exchange of plate-type heat exchanger 3, obtains cooling during this period, can obtain recycling.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
Claims (2)
1. polyester process waste water stripping separating and treating apparatus; Comprise aldehyde-containing sewage pond, stripping tower; It is characterized in that: said aldehyde-containing sewage pond is connected with the water inlet of stripping tower through water inlet pipe and water inlet pipe is provided with intake pump; And the waste water filling is connected and rising pipe is provided with out water pump through rising pipe for the water outlet of stripping tower; Also be provided with open steam on the stripping tower and go into pipe and go into pipe with indirect steam, open steam is gone into to manage and is gone into the Guan Junyu vapour generator with indirect steam and be connected, and the air outlet of stripping tower is connected with boiler through escape pipe.
