Description

Technical Field

[0001] This application belongs to the technical field of wastewater treatment, and particularly relates to a multi-type sewage zoning collection device for substations. Background Art

[0002] A substation refers to an industrial facility in the power system that transforms voltage and current, receives electrical energy, and distributes electrical energy. It has the characteristics of small floor area, many live electrical equipment, few staff, scattered water consumption, and often being far from densely populated areas. With the rapid improvement of the national industrialization level, the electricity consumption in various regions has increased sharply. Therefore, the number of substations has been gradually increasing in recent years, and at the same time, the wastewater treatment of substations has become an important issue faced by local environmental departments.

[0003] The sewage in substations mainly includes domestic water, oil-containing wastewater, and natural precipitation. Common sewage treatment methods for substations in the prior art include anaerobic fermentation treatment method, aerobic treatment method, chemical method, and high-temperature and high-pressure treatment method; usually, substations will select one or more of these sewage treatment methods for wastewater treatment according to actual needs. Since the types of sewage are different, when treating it, it is necessary to classify according to the source of the sewage. The existing classification method is achieved through pipelines. Specifically, according to the transportation pipelines at the sewage source, different sewage is respectively input into different areas for treatment.

[0004] According to regional differences, some substations in some areas implement an unattended mode. Specifically, with the help of automation technologies such as microcomputer telecontrol, the duty personnel can obtain relevant information remotely and control and manage the operation of the substation equipment. In this mode, the sewage in the substation mainly manifests as natural precipitation, so the area corresponding to natural precipitation will be larger; while when manually guarding such substations (usually in cooperation with automation technologies for management and control, or for repairing and maintaining the equipment in the substation), the domestic water consumption will increase significantly.

[0005] The inventor found that when treating the sewage of substations that can implement the unattended mode, there is often a technical problem that some treatment areas are filled, while some treatment areas are idle, resulting in a reduction in sewage treatment efficiency.

Detailed implementation manners

[0041] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] Please refer to Figures 1 to 8 together, and now a multi-class sewage partition collection device for a substation provided by the present application will be described. The multi-class sewage partition collection device proposed by the present application includes a base 1, a partition board 2 and a flow splitting assembly 3.

[0043] The base 1 adopts a seat body structure with a rectangular cross-section. In this embodiment, for the convenience of description, the length direction of the base 1 is defined as the left-right direction, the width direction of the base 1 is defined as the front-back direction, and the height direction of the base 1 is defined as the up-down direction.

[0044] The base 1 has a water storage cavity 11 and a plurality of static chambers 12.

[0045] Among them, the water storage cavity 11 penetrates the upper surface of the base 1, adopts a cavity structure with a rectangular cross-section, and the length direction of this rectangle is parallel to the left-right direction.

[0046] In addition, a plurality of static chambers 12 are spaced apart in the vertical direction and are located on the left or right side of the water storage chamber 11. Moreover, the cross-section of each static chamber 12 is rectangular, and the length direction of this rectangle is parallel to the front-rear direction.

[0047] The partition 2 is made of a rigid plate. Its body is slidably connected to the bottom surface of the above-mentioned water storage chamber 11 in the left-right direction, and its front and rear sides are both abutted against the inner wall of the water storage chamber 11 to divide the water storage chamber 11 into a first chamber 111 and a second chamber 112; among them, the first chamber 111 is used to hold natural precipitation, and the second chamber 112 is used to hold domestic water.

[0048] It should be added that, in this embodiment, as Figure 3 shown, a columnar rubber part is connected to the lower end of the partition 2. The function of this rubber part is to fill the gap between the partition 2 and the bottom surface of the water storage chamber 11 to ensure that there is no fluid communication between the first chamber 111 and the second chamber 112.

[0049] As Figure 3 shown, the second chamber 112 is located between the first chamber 111 and the static chambers 12. Therefore, compared with the second chamber 112, the first chamber 111 is located farther away from the static chambers 12. The purpose of such a design is:

[0050] The liquid contained in the first chamber 111 is natural precipitation, which can be discharged to the outside after being filtered; and the conventional discharge method is to directly discharge it into the land below. Therefore, setting the first chamber 111 at a position far from the static chambers 12 can avoid the treated natural precipitation from affecting the relevant components of the static chambers 12.

[0051] It should be added that the liquid contained in the second chamber 112 is domestic water, and the conventional treatment method is the chemical method, that is, chemical substances that can react with the dirt in the domestic water are added to the second chamber 112 to make part of the impurities in the domestic water be treated.

[0052] Therefore, the position where the second chamber 112 is located is not restricted by the above; and since the unattended mode is a common management mode for substations using such a collection device, setting the above-mentioned second chamber 112 between the first chamber 111 and the static chambers 12 can avoid the influence between the first chamber 111 and the static chambers 12 and play a role of isolation and protection.

[0053] The flow splitting component 3 has the function of collecting oil-containing wastewater and discharging it quantitatively; in this embodiment, the flow splitting component 3 is communicated with the above-mentioned plurality of static chambers 12 and is used to sequentially discharge a certain amount of oil-containing wastewater into the plurality of static chambers 12. The purpose of such a design is:

[0054] Since the oily wastewater in the static chamber 12 is quantitative, there will be no over - flow situation, and the required static time is controllable, which is convenient for the static separation treatment of oily wastewater and realizes the effective collection and preservation of the wastewater.

[0055] In the embodiment of the present application, the first chamber 111, the second chamber 112 and multiple static chambers 12 are respectively used to accommodate natural precipitation, domestic water and oily wastewater, so as to realize the classified treatment of various types of sewage in the substation; when different management modes are adopted in the substation, on - site operators can divide the water storage chamber 11 by adjusting the position of the partition plate 2 to achieve the purpose of changing the capacities of the first chamber 111 and the second chamber 112, so as to adaptively collect domestic water and natural precipitation under different modes.

[0056] Meanwhile, through the equal - division effect of the flow - splitting component 3, the oily wastewater is discharged into different static chambers 12 in a quantitative manner to complete static settlement, avoiding the influence on the static separation process of oily wastewater when the oily wastewater is discharged into a single space in batches, and ensuring the treatment efficiency of the oily wastewater.

[0057] Compared with the prior art, the device for classified collection of various types of sewage in the substation provided by this embodiment can adapt to different management modes of the substation and ensure the stability of the sewage treatment efficiency.

[0058] In some embodiments, the above - mentioned flow - splitting component 3 can adopt structures such as Figure 2 , Figure 6 and Figure 7 as shown. Referring to Figure 2 , Figure 6 and Figure 7 , the flow - splitting component 3 includes a base tower 31 and a water - collecting cylinder 32.

[0059] The base tower 31 is used to be arranged side - by - side in front of or behind the base 1 and is directly behind the static chamber 12, adopting a tower - body structure extending from bottom to top.

[0060] The water - collecting cylinder 32 is fixedly arranged on the base tower 31 and is above the base 1, specifically above the static chamber 12, so as to facilitate the fluid to enter the static chamber 12 by gravity.

[0061] In this embodiment, the water - collecting cylinder 32 has a cylinder cavity 321 penetrating its upper surface, and a cylinder cover 4 detachably connected to the upper end of the water - collecting cylinder 32 is adapted to close the cylinder cavity 321; through the closing effect of the cylinder cover 4 on the cylinder cavity 321, it can play a role in preventing external dust or impurities from entering the cylinder cavity 321.

[0062] The lower surface of the water collecting cylinder 32 is connected with a plurality of inner drain pipes 322, and the number of the plurality of inner drain pipes 322 is equal to that of the aforementioned plurality of static chambers 12. In this embodiment, this number is three; the plurality of inner drain pipes 322 are all communicated with the cylinder cavity 321 to discharge the oily wastewater in the cylinder cavity 321.

[0063] Each inner drain pipe 322 is communicated with the corresponding static chamber 12 and is connected with an inner drain valve 3221 that can control the opening and closing of the inner space of the pipe; when the inner drain valve 3221 is in the open state, the oily wastewater in the cylinder cavity 321 can flow into the corresponding static chamber 12 through the inner drain pipe 322.

[0064] A water inlet pipe 41 is connected to the cylinder cover 4, and a stop valve 411 is connected to the water inlet pipe 41; the water inlet pipe 41 is used to communicate with the source module of the oily wastewater. When the cylinder cover 4 is connected to the water collecting cylinder 32, the water inlet pipe 41 is communicated with the cylinder cavity 321; at the same time, opening the stop valve 411 can make the oily wastewater enter the inside of the above-mentioned cylinder cavity 321 through the water inlet pipe 41.

[0065] A water level monitoring element 42 is also connected to the cylinder cover 4; when the cylinder cover 4 is connected to the water collecting cylinder 32, the water level monitoring element 42 is inside the cylinder cavity 321 to monitor the liquid level height in the cylinder cavity 321, so as to cooperate with on-site operators to manually control the device, or cooperate with a prefabricated external automation system to manage the timed and quantitative discharge of the oily wastewater.

[0066] By adopting the above technical solutions, the collection of the oily wastewater and the batch and quantitative discharge to different static chambers 12 are realized, and the structural stability of the device is improved.

[0067] In some embodiments, the following structure can be adopted between the above-mentioned feature base 1 and the static chamber 12 Figure 4 and Figure 5 as shown. Refer to Figure 4 and Figure 5 , a plurality of outer drain pipes 5 that are in one-to-one correspondence and communication with the plurality of static chambers 12 are arranged on the base 1, and an outer drain valve 51 is connected to the outer drain pipes 5; when the outer drain valve 51 is in the open state, the liquid in the static chamber 12 will be discharged through the outer drain pipe 5.

[0068] In the above process, if the oily wastewater in the static chamber 12 has been static, the outer drain pipe 5 will first discharge a part of the statically stratified layer and then discharge the other part; at the same time, by controlling the interface of the outer drain pipe 5, the preliminary collection of the water body and the oil-water mixture can be realized.

[0069] It should be added that, in this embodiment, as Figure 5As shown, the bottom surface of the static chamber 12 is an inclined surface to ensure that the fluid flows towards the outer drain pipe 5, so as to ensure the complete discharge of the fluid and avoid the technical problem of difficult cleaning caused by the residue of oily wastewater.

[0070] Each static chamber 12 is configured with a control module. The operating principle of this control module is: after the corresponding inner drain pipe 322 discharges oily wastewater into the static chamber 12, the control module can restrict the inner drain valve 3221 from starting again until the outer drain valve 51 starts.

[0071] Specifically, during the process of discharging oily wastewater into the static chamber 12, the above-mentioned inner drain valve 3221 is opened first and closed after a certain amount of oily wastewater is drained; after the oily wastewater is static, the above-mentioned outer drain valve 51 is started first and closed after the internal oily wastewater is completely discharged.

[0072] During the process from the closing of the inner drain valve 3221 to the closing of the outer drain valve 51, the control module restricts the start of the inner drain valve 3221 to avoid adding impurities to the oily wastewater in the static state and during the discharge process, improving the stability of the device during actual use.

[0073] In some embodiments, the above-mentioned feature cylinder cover 4 and the water collecting cylinder 32 can adopt structures such as Figure 6 and Figure 7 as shown. Refer to Figure 6 and Figure 7 . The cylinder cover 4 has a plurality of exhaust holes 43. When the cylinder cover 4 is connected to the water collecting cylinder 32, the exhaust holes 43 are communicated with the cylinder cavity 321 to discharge the gas in the cylinder cavity 321 and ensure the stability of the pressure inside and outside the cylinder cavity 321.

[0074] A purification component for closing the exhaust holes 43 is also connected to the upper surface of the cylinder cover 4. Through this purification component, the gas discharged from the exhaust holes 43 can be purified to improve the environmental protection of the on-site ambient gas.

[0075] The purification component includes two layers of purification nets 6. The two purification nets 6 are distributed vertically, and a chemical substance capable of purifying the gas emitted from the oily wastewater is suitable to be added between the two layers of purification nets 6; it should be added that in this embodiment, the chemical substance capable of purifying the gas emitted from the oily wastewater belongs to the prior art and will not be elaborated here.

[0076] The upper surface of the cylinder cover 4 has a plurality of positioning piles 44 distributed around the plurality of exhaust holes 43. In this embodiment, there are four positioning piles 44 and they are distributed at the four corners of a rectangle. The purification net 6 is made of an elastic material, and its surface has a plurality of through holes 61 corresponding to the plurality of positioning piles 44 one by one. During actual installation, the purification net 6 can be installed by pulling the purification net 6 and sleeving the through holes 61 on the positioning piles 44, and this installation method is convenient for replacement and ensures the disassembly and assembly efficiency.

[0077] Since the oily wastewater is not continuously discharged into the cylinder cavity 321, during the process of some oily wastewater being discharged into the cylinder cavity 321 and waiting for the wastewater volume to meet the standards, a relatively long time will pass; on this basis, by adopting the above technical solution, the gas can be purified through the purification net 6, ensuring environmental protection of the environmental gas while reducing the later treatment process of the oily wastewater and improving the treatment efficiency of the oily wastewater.

[0078] In some embodiments, the above-mentioned characteristic base 1 and the static chamber 12 can adopt structures such as Figure 2 and Figure 5 as shown. Refer to Figure 2 and Figure 5 . The base 1 is provided with a plurality of pressure relief holes 121 corresponding to and communicating with the plurality of static chambers 12 one by one. Through the action of the pressure relief holes 121, the air pressure balance inside and outside the static chamber 12 can be ensured, improving the stability of the device.

[0079] When a fixed amount of oily wastewater is discharged into the static chamber 12, the liquid level of the oily wastewater is below the pressure relief hole 121 to prevent the oily wastewater from flowing out of the static chamber 12 through the pressure relief hole 121.

[0080] In some embodiments, the above-mentioned characteristic base 1 and the partition 2 can adopt structures such as Figure 1 , Figure 3 and Figure 8 as shown. Refer to Figure 1 , Figure 3 and Figure 8 . Both the front and rear sides of the base 1 are provided with guiding holes 13 communicating with the water storage cavity 11. Both the front and rear sides of the partition 2 are connected with clamping arms 21 adapted to pass through the corresponding guiding holes 13 and extend out, and the extending end of each clamping arm 21 is integrally connected with a limiting portion 22 adapted to abut against the front side or the rear side of the base 1.

[0081] Among them, when the clamping arm 21 abuts against the left end wall or the right end wall of the guiding hole 13, there is a gap between the partition 2 and the inner walls on the left and right sides of the water storage cavity 11 to prevent the space of the first chamber 111 or the second chamber 112 from being too small, resulting in the loss of its ability to collect sewage, and improving the stability of the device.

[0082] By adopting the above technical solution, the combined structure of the clamping arm 21 and the limiting portion 22 cooperates with the guiding hole 13 to realize the sliding connection relationship between the base 1 and the partition 2, and limit the sliding direction of the partition 2, improving the stability of the device during actual use and ensuring that the partition 2 is in a vertical state.

[0083] In some embodiments, the above-mentioned characteristic base 1 can adopt a structure such as Figure 4 as shown. Refer to Figure 4, the base 1 further includes a driving screw 7 and a rotating motor 71.

[0084] The driving screw 7 is arranged on the front side or the rear side of the base 1, its axial direction is parallel to the left - right direction, and it is rotatably connected to the base 1; the driving screw 7 is threadedly connected to the limiting part 22 on the corresponding side.

[0085] The rotating motor 71 is fixedly arranged on the base 1 and is in transmission connection with the driving screw 7.

[0086] By adopting the above - mentioned technical solution, the rotating motor 71 can drive the driving screw 7 to rotate, so as to drive the partition plate 2 to slide in the left - right direction through the limiting part 22, realizing the automatic driving of the partition plate 2, so that the device has the prerequisite ability for remote operation.

[0087] In some embodiments, the above - mentioned feature base 1 can adopt the structure as shown in Figure 1 and Figure 4 . Refer to Figure 1 and Figure 4 , the base 1 further includes a seat cover 8.

[0088] The seat cover 8 is hinged on the upper surface of the base 1 in the front - rear direction, having a use state of swinging to close the water storage cavity 11 and an open state of swinging to support on the upper surface of the base 1.

[0089] Among them, the seat cover 8 has a plurality of embedding grooves 81, and the upper end surface of the partition plate 2 has a positioning block 23 adapted to be embedded in any one of the embedding grooves 81; when the seat cover 8 is in the use state, the positioning block 23 is in contact with the bottom of one of the embedding grooves 81.

[0090] The reason for setting the embedding grooves 81 on the seat cover 8 instead of setting the positioning blocks 23 on the seat cover 8 is that during the process of adjusting the state of the seat cover 8, the seat cover 8 is a moving part relative to the partition plate 2. When the embedding grooves 81 are not aligned with the positioning blocks 23, the positioning blocks 23 will support on the surface of the seat cover 8 to limit its swinging to the use state. Thus, it can not only position the sliding of the partition plate 2 but also ensure the state of the seat cover 8, improving the stability of the device during actual use.

[0091] By adopting the above - mentioned technical solution, the seat cover 8 can play a role in closing the water storage cavity 11 to prevent the internal sewage gas from affecting the on - site environment; in addition, the positioning effect of the embedding grooves 81 and the positioning blocks 23 can position the seat cover 8, improving the structural stability of the device.

[0092] In some embodiments, the structure between the above - mentioned feature base 1 and the water storage cavity 11 can be as shown in Figure 1 and Figure 4 . Refer to Figure 1 and Figure 4, a first pipeline 14 for discharging natural precipitation and communicating with the first chamber 111 is connected to the side surface of the base 1, and a second pipeline 15 for discharging domestic water and communicating with the second chamber 112 is also connected thereto.

[0093] By adopting the above technical solution, sewage is discharged into the first chamber 111 and the second chamber 112 through the first pipeline 14 and the second pipeline 15. Compared with the method of discharging sewage through the upper opening of the self-water storage chamber 11, liquid overflow is avoided, and stronger stability is achieved; on the other hand, it is possible to avoid opening the seat cover 8, optimize the liquid adding process, and improve the stability of discharging sewage into the first chamber 111 and the second chamber 112.

[0094] In some embodiments, the above-described structure can be adopted between the base 1 and the first chamber 111 as Figure 3 shown. Refer to Figure 3 , a drain port 16 communicating with the first chamber 111 is provided on the lower surface of the base 1. A plurality of layers of filter screens 9 are spaced apart in the vertical direction within the drain port 16, and chemicals capable of filtering natural precipitation are adapted to be added between adjacent two layers of filter screens 9.

[0095] It should be added that chemicals capable of filtering natural precipitation belong to the prior art and will not be elaborated herein.

[0096] By adopting the above technical solution, the plurality of layers of filter screens 9 will filter out impurities in the natural precipitation and can locate the chemicals, ensuring the filtration treatment of natural precipitation and improving the treatment efficiency of natural precipitation.

[0097] The above content is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
