Description

Technical Field

[0001] The utility model relates to the engineering technical fields of ventilation and deodorization of regulating and storing ponds and water environment improvement, and in particular to a ventilation well structure for a small landscape piece on the water surface of an initial rain regulating and storing pond. Background Art

[0002] Initial rainwater storage ponds are primarily used for regulating and storing initial rainwater. Rainwater regulation refers to the temporary storage of a certain amount of rainwater during rainfall, reducing peak downstream discharge flows and extending discharge duration to achieve peak flow reduction. Rainwater storage involves the storage, detention, sedimentation, infiltration, or filtration of runoff rainwater to control the total volume and peak flow rate, thereby controlling runoff pollution and allowing for runoff recovery and reuse. Initial rainwater storage ponds can be used to control non-point source pollution, reduce peak flow, and reduce the hydraulic and pollution loads on sewage pipes and treatment facilities during rainfall.

[0003] During operation, the first rain storage tank will produce a large amount of foul-smelling gases and odors. The odors are unpleasant to the senses and may even endanger human physiological health, such as difficulty breathing, back-feeding, chest tightness, vomiting, etc. These odors are mainly caused by gases produced by the decay of organic matter. The odors generally include special odors such as fish odor, ammonia odor, rotten meat odor, rotten egg odor, rotten cabbage odor, etc. In order to prevent and eliminate the adverse effects of the odors produced by the first rain storage tank on the surrounding environment and residents' lives, the odors must be controlled and treated. The common practice at present is to set up several ventilation shafts higher than the storage tank body in the top space of the storage tank to allow air to circulate inside and outside the tank body, but it is easy to cause the odor in the tank to spread outside the tank body, affecting the surrounding environment and causing discomfort to people moving around.

[0004] Waterfront landscapes and waterbody designs often incorporate pavilions, curved bridges, lawns along the water, and trees, creating a mix of high and low vistas. The changing scenery of the seasons creates a diverse landscape space and atmosphere. The design of the portion above the water surface follows the garden landscape, with pavilions, terraces, landscaped rock formations, and sculptures. As the construction of regulating reservoirs increases the use of green space and other land resources, integrating the design of the above-ground and water surface areas of the reservoirs with the landscaping has become a design trend. How to integrate the function of ventilation shafts with the landscape environment, intensively utilize green space and water bodies, rationally arrange above- and underground spaces, integrate the above-water portion of the regulating reservoir with the surrounding water environment, and design a water ventilation shaft that aligns with the overall garden concept and meets the functional requirements of the regulating reservoir has become a key design node and optimization point.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0035] See also Figures 3 to 5 Combined with Figure 1 and Figure 2 The figure shows a ventilation shaft structure of a small landscape feature on the surface of an initial rain storage pond, including a ventilation shaft body 100, an ellipsoidal structure 200, a cylindrical structure 300, rainproof ventilation windows 400a, 400b, deodorizing and filtering devices 500a, 500b, a landscape decoration structure 600 and an anti-fall net 700.

[0036] The ventilation shaft body 100 is constructed on the top plate 11 of the primary rain storage tank 10, and the lower end of the ventilation shaft body 100 is connected to the ventilation hole 11a opened on the top plate 11 of the primary rain storage tank 10. The ventilation shaft body 100 is in the shape of a rectangular column as a whole, and adopts a reinforced concrete structure, serving as the upper ventilation structure part of the top plate 11 of the primary rain storage tank 10. The top surface elevation of the ventilation shaft body 100 is higher than the designed high water level of the water surface, to prevent lake water from entering the primary rain storage tank 10 when the water level rises, affecting the normal use of the facility during the rainy season. In addition, the outer peripheral surface of the ventilation shaft body 100 is coated with colored paint or plain concrete, and sprayed with a waterproof protective film, and its inner peripheral surface is treated with anti-corrosion, which not only improves the aesthetics but also extends the service life.

[0037] The ellipsoidal structure 200 is constructed on the upper end of the ventilation shaft body 100 and its interior is communicated with the interior of the ventilation shaft body 100. In this embodiment, the ellipsoidal structure 200 adopts a reinforced concrete structure.

[0038] The rainproof ventilation window 400a is mounted on the outer surface of the ellipsoidal structure 200. In this embodiment, the rainproof ventilation window 400a is installed in a removable manner, such as by snap-on mounting or screw mounting, to facilitate removal. The rainproof ventilation window 400a utilizes a fixed louver with rain-proof blades, made of materials such as stainless steel or aluminum alloy. This effectively prevents rainwater from entering the ventilation shaft and potentially dampening the cylindrical filter, thereby extending the replacement cycle of the cylindrical filter. The effective exhaust area of ​​the rainproof ventilation window 400a must be determined through calculation.

[0039] The deodorizing filter device 500a is installed within the ellipsoidal structure 200. In this embodiment, the deodorizing filter device 500a comprises a plurality of filter support platforms 510a and a plurality of cylindrical filters 520a. The filter support platforms 510a are vertically spaced apart within the ellipsoidal structure 200. The filter support platforms 510a are made of 304 stainless steel and effectively support the cylindrical filters 520a. The cylindrical filters 520a are arranged side by side on each filter support platform 510a.

[0040] The cylindrical structure 300 is constructed on the top surface of the ellipsoidal structure 200 and its interior is communicated with the interior of the ellipsoidal structure 200. In this embodiment, the cylindrical structure 300 adopts a reinforced concrete structure.

[0041] The rainproof ventilation window 400b is mounted on the outer surface of the cylindrical structure 300. In this embodiment, the rainproof ventilation window 400b is installed in a removable manner, such as by snap-on mounting or screw mounting, to facilitate removal. The rainproof ventilation window 400b utilizes a fixed louver with rain-proof blades, made of materials such as stainless steel or aluminum alloy. This effectively prevents rainwater from entering the ventilation shaft and potentially dampening the cylindrical filter, thereby extending the replacement cycle of the cylindrical filter. The effective exhaust area of ​​the rainproof ventilation window 400b must be determined through calculation.

[0042] The deodorizing filter device 500b is installed within the cylindrical structure 300. In this embodiment, the deodorizing filter device 500b comprises a plurality of filter support platforms 510b and a plurality of cylindrical filters 520b. The filter support platforms 510b are vertically spaced apart within the cylindrical structure 300. The filter support platforms 510b are made of 304 stainless steel and effectively support the cylindrical filters 520b. The cylindrical filters 520b are arranged side by side on each filter support platform 510b.

[0043] The cylindrical filters 520a and 520b use modular, detachable, non-powered dry chemical filter cartridges, which are easy to unload and replace with new filter cartridges. The deodorization principle of dry chemical filtration is mainly divided into two steps: physical adsorption and chemical reaction. The dry chemical filter material is mixed with adsorption materials and chemically active substances represented by chemical oxidants. When the air passes through the filter layer, the pollutants contained in the air (such as H2S, NH3, formaldehyde, organic acids and other VOCs) are adsorbed to the surface of the filter material by physical adsorption, and then reacted with the effective chemical components in the filter material to convert them into harmless products (such as salt, CO2 and water, etc.). The core of the chemical reaction is the chemical catalytic oxidation reaction of related substances. For the main components of the odor, hydrogen sulfide and ammonia, the main chemical reaction equations occurring in this process are as follows:

[0044] 2H2S+O2=2H2O+2S

[0045] 5H2S+2KMnO4+3H2SO4=2MnSO4+K2SO4+5S+8H2O

[0046] H3PO4+NH3=(NH4)H2PO4

[0047] The gas treated by the cylindrical filters 520a and 520b must ensure that it meets the "Emission Standard of Odor Pollutants" (GB14554-1993), the "Technical Code for Odor Treatment in Urban Wastewater Treatment Plants" (CJJ / T243-2016) and the local emission standards requirements of the storage tank construction project.

[0048] The landscape decoration structure 600 is installed on the top surface of the cylindrical structure 300. The landscape decoration structure 600 is a gourd-shaped structure.

[0049] The anti-fall net 700 is installed within the ventilation shaft body 100, below the water surface. The rope of the anti-fall net 700 can be made of nylon, vinylon, polyester, or other materials. Its physical properties and weather resistance must comply with relevant national or industry standards. The net should have a load capacity greater than 300 kg and a single rope tension of 1600 N.

[0050] During construction and installation, the ventilation shaft structure for the initial rainwater storage pond landscape feature of the present invention is installed from bottom to top. First, the anti-fall net 700 is installed on the sidewall of the ventilation shaft body 100, located below the ellipsoidal structure 200. Expansion bolts with hooks are driven into the sidewall, with the fixing bolts evenly distributed along the same horizontal plane within the sidewall, with the hooks facing upward. The anti-fall net 700 is then installed. Next, the filter support platforms 510a and 510b are installed within the ellipsoidal structure 200 and the cylindrical structure 300. The cylindrical filters 520a and 520b are then mounted on the filter support platforms 510a and 510b, and rainproof ventilation windows 400a and 400b are installed. Finally, the landscape decorative structure 600 is installed on the top surface of the cylindrical structure 300. When the cylindrical filter 520a or the cylindrical filter 520b needs to be replaced, the rainproof ventilation window 400a or the rainproof ventilation window 400b can be uninstalled, and the cylindrical filter 520a or the cylindrical filter 520b can be taken out for replacement.

[0051] The ventilation shaft structure of the first rain storage pool water surface landscape sketch of the present invention adopts a gourd-shaped decoration on the top, a cylindrical shape on the upper part, an ellipsoid shape on the lower part, and a frustum shape on the base, which are combined into a classic brick tower shape of "Three Pools Mirroring the Moon". Under the influence of light and shadow during the day and at night, the three elements of "water surface, ventilation shaft body, and reflection" are combined through the reflection of the body on the water surface. The three elements of "point, line, and surface" are integrated to create space, limit space, and guide space in the landscape, while giving space momentum, making the static landscape dynamic and vital, increasing the interest and attraction of the space, and enriching the spatial level.

[0052] The number of ventilation shaft structures of the landscape sketch of the initial rain storage pond of this utility model needs to be reasonably arranged in plane considering factors such as the internal pressure of the storage pond, the deodorization air volume, and the volume of the storage pond. Figure 1 or Figure 2 shown.
