Description
Technical Field
The utility model relates to a sewage treatment technical field, concretely relates to closed water circulation vacuum device.
Background
The existing fatty acid distillation and soap grain production device adopts a water spraying vacuum device system, tap water or other treated water sources are directly contacted and mixed with non-condensable gas to generate vacuum after passing through the water spraying vacuum device, and then the vacuum is discharged to a sewage treatment workshop for treatment. However, the current sewage treatment vacuum device has very large water consumption and large wastewater output, the wastewater treatment cost reaches 14 yuan/ton, tens of thousands of tons of wastewater need to be treated every day, the wastewater is uneconomical, the sewage temperature is high and difficult to treat, and the wastewater needs to be specially provided with a power pump and conveyed to a sewage treatment workshop for regeneration treatment, so the power consumption is high, and the wastewater is uneconomical and energy-saving.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a closed water circulation vacuum device to the defect and not enough of prior art.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a closed water circulation vacuum device, includes a plurality of cooling tower, plate heat exchanger and sewage recovery workshop, its innovation point lies in: the cooling tower upper end is the water inlet, the lower extreme is the delivery port, the equal external sewage source of water inlet, the delivery port all with sewage recovery workshop fixed connection, cooling tower is located the eminence, and establishes ties through plate heat exchanger to the side, plate heat exchanger is also external sewage source, and along sewage flow to, also with sewage recovery workshop fixed connection at the plate heat exchanger that lies in sewage flow to terminal.
Furthermore, the sewage treatment system also comprises a hot well, wherein one end of the hot well is connected with a sewage source, and the other end of the hot well is fixedly connected with a sewage recovery workshop.
After the structure is adopted, the utility model discloses beneficial effect does:
the utility model has simple structure, convenient use and lower cost, the plate heat exchanger is used for indirect heat exchange with cooling water from the cooling tower, one is used for the other, the heat exchanger adopts the plate heat exchanger, the occupied space can be greatly saved, the cooling tower is placed at a high position in a workshop, the lift of a circulating pump can be reduced, and the model selection of the motor is small; and redundant sewage overflows to a sewage recovery workshop through a hot well for further treatment, so that the sewage quantity is greatly reduced, and the method is economical, environment-friendly and energy-saving.

Description of reference numerals:
1 cooling water tower, 2 plate heat exchangers, 3 sewage recovery workshops, 4 heat wells.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
Referring to fig. 1, a closed water circulation vacuum device comprises a plurality of cooling water towers 1, plate heat exchangers 2 and a sewage recovery workshop 3, wherein the upper ends of the cooling water towers 1 are water inlets, the lower ends of the cooling water towers are water outlets, the water inlets are externally connected with a sewage source, the water outlets are fixedly connected with the sewage recovery workshop 3, the cooling water towers 1 are positioned at high positions, the side surfaces of the cooling water towers are connected in series through the plate heat exchangers 2, the plate heat exchangers 2 are also externally connected with the sewage source, and the plate heat exchangers 2 positioned at the tail ends of the sewage flow direction are also fixedly connected with the sewage recovery workshop 3 along the sewage flow; spray water closed cycle is adopted inside the cooling water tower 1, and heat exchange is carried out with the cooling water from the cooling water tower 1 through the plate heat exchanger 2, so that the sewage output is greatly reduced.
In this example, the temperature of the cooling water is 32 to 42 ℃, and the pressure of the cooling water is: 3-5 barg.
In this embodiment, the system further comprises a hot well 4, wherein one end of the hot well 4 is connected with a sewage source, and the other end of the hot well 4 is fixedly connected with the sewage recovery workshop 3. And redundant sewage overflows to the sewage recovery workshop 3 through the hot well 4 for further treatment, so that the sewage quantity is greatly reduced, and the method is economical, environment-friendly and energy-saving.
The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
