Description

Technical Field

[0001] This utility model relates to the field of oilfield surface engineering, specifically to a closed-loop wastewater treatment flocculant dosing device. Background Technology

[0002] Effective treatment of water in oil and gas fields is crucial for the development of the petroleum industry. Flocculants are important agents for treating suspended solids in oil and gas field water; they are mixed with water in a specific ratio and continuously added to the wastewater dosing system. Due to production needs and to ensure that wastewater quality indicators meet standards, the wastewater dosing system needs to operate continuously for 24 hours and requires regular dosing.

[0003] The flocculant is in powder form, packaged in a kraft paper bag weighing approximately 25 kg. Traditional flocculant dosing is done via an open-loop system. During dosing, the operator places the kraft paper bag on the dosing tank, punctures it with a blade, and then pours the flocculant into the tank. Because the flocculant is an organic sulfur mixture, inhalation of the powdered flocculant can irritate the nasal cavity and throat, and contact with the eyes can cause irreversible eye damage due to corrosion. Skin contact can cause burns and allergic reactions. Therefore, operators must wear heavy protective gear such as gas masks, gloves, and goggles. This traditional dosing method is time-consuming and labor-intensive. Careless puncturing of the bag can easily cause injury, and improper blade handling can also lead to accidents. Furthermore, during the pouring process, the powdered flocculant can easily spill into the surrounding environment, causing pollution. Summary of the Invention

[0004] In view of this, the present invention provides a closed-loop flocculant dosing device for sewage treatment, which solves the problems of traditional flocculant dosing methods being time-consuming and labor-intensive, and easily causing personal injury and environmental pollution.

[0005] To achieve the above-mentioned objective, the closed-loop wastewater treatment flocculant dosing device comprises:

[0006] A box with a top cover, the box containing a spiked structure;

[0007] The spiked structure is used to puncture the flocculant packaging bag, so that the flocculant in the packaging bag flows out from the puncture and is added to the dosing system.

[0008] In this disclosure and possible embodiments, the bottom of the box body adopts a sloping structure.

[0009] In this disclosure and possible embodiments, a drainage conduit is provided at the lowest position of the inclined structure, and the flocculant is added to the dosing system through the drainage conduit.

[0010] In this disclosure and possible embodiments, the outer wall of the box is provided with a snap-fit ​​structure, and the box is snapped into the dosing box of the dosing system through the snap-fit ​​structure.

[0011] In this disclosure and possible embodiments, a sealing structure is provided between the top cover and the upper port of the housing.

[0012] In this disclosure and possible embodiments, the spike structure is fixed to the inner wall of the box and located above the drainage conduit.

[0013] In this disclosure and possible embodiments, there is a gap between the housing and the dosing tank.

[0014] The beneficial effects of this utility model are:

[0015] This utility model discloses a closed-loop flocculant dosing device for wastewater treatment. When dosing flocculant, simply insert the entire package of flocculant into the tank. The flocculant packaging bag will immediately be punctured by the spiked structure inside the tank. Once punctured, the flocculant powder will flow into the oilfield wastewater dosing system through the puncture. Using this dosing device, the dosing process is carried out within a closed system, constituting a fully enclosed operation. This effectively prevents the flocculant powder from spreading in the environment, minimizing damage to the operator's eyes, skin, and nasal cavity caused by the flocculant powder diffusion. It also minimizes the amount of flocculant powder scattered in the surrounding environment, achieving the goals of closed, safe, and environmentally friendly dosing. Attached Figure Description

[0021] The present disclosure is described below based on embodiments; however, it is worth noting that the present disclosure is not limited to these embodiments. In the detailed description of the present disclosure below, certain specific details are described in detail. However, those skilled in the art will fully understand the present disclosure for the parts not described in detail.

[0022] Furthermore, unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to."

[0023] Depend on Figure 1-4 As shown in the embodiment of this disclosure, a closed-loop wastewater treatment flocculant dosing device includes: a box 1 with a top cover, wherein a spike structure 3 is provided inside the box 1; the spike structure is used to puncture the packaging bag of the flocculant so that the flocculant in the packaging bag flows out from the puncture and is added to the dosing system.

[0024] In this embodiment, it is preferable that the bottom of the box 1 adopts a sloping structure 5. The design of the sloping structure 5 is conducive to the flocculant powder falling into the bottom of the box 1 flowing quickly into the dosing system under the action of gravity.

[0025] In this embodiment, it is preferable to set the drainage conduit 4 at the lowest position of the inclined structure 5, so that the flocculant powder at the bottom of the box 1 can be added to the dosing system through the drainage conduit 4.

[0026] In this embodiment, a snap-fit ​​structure 2 is preferably provided on the outer wall of the box 1. The box 1 can be snapped to the dosing box of the dosing system through the snap-fit ​​structure 2. That is, the box 1 sits on the existing dosing box of the dosing system through the snap-fit ​​structure 2, without the need to make any modifications to the original dosing system, and can be used directly.

[0027] In this embodiment, a sealing structure is preferably provided between the top cover and the upper port of the box 1. This sealing structure can be a sealing design with an edge-sealing of the top cover, or a sealing element, such as a sealing ring, can be provided on the upper port of the box 1. In this way, when the top cover is placed on the upper port of the box 1, the contact surface between the two is in sealed contact, thereby ensuring the airtightness of the box 1. When the entire bag of flocculant is added into the box 1 and the top cover is closed, although the flocculant packaging bag has been punctured at this time and the flocculant powder falls into the box 1 and forms a powder dispersion state, the powder is completely sealed inside the box 1 and will not diffuse into the external environment of the box 1. This effectively prevents the operator from inhaling the flocculant powder and avoids contact with the flocculant powder, reducing the corrosive damage to the operator's nose, eyes and skin.

[0028] In this embodiment, the spike structure 3 is preferably fixed on the inner wall of the box 1 and located above the drainage conduit 4. The spike structure 3 can be a commonly used cone-shaped structure, which can be sheet-like or three-dimensional cone-shaped. This application does not limit this, as long as the design is conducive to quickly piercing the flocculant packaging bag.

[0029] In this embodiment, it is preferable that there is a gap between the box body 1 and the dosing box of the dosing system, which facilitates the smooth flow of flocculant powder into the dosing box and the dosing system.

[0030] The working process of the closed-type flocculant dosing device for wastewater treatment of this utility model is described in detail below with reference to the accompanying drawings:

[0031] The entire package of flocculant is placed into the housing 1 of the flocculant dosing device of this application, and the lid is closed. Once the flocculant packaging bag falls into the housing 1, it will be immediately punctured by the spike structure 3 inside the housing 1. Once the sharp tip of the spike structure 3 punctures the packaging bag, the flocculant powder will flow out along the sharp tip and flow directly into the bottom of the dosing tank of the original dosing system along the drainage pipe 4. Because the bottom of the housing 1 is designed with a slope and the housing 1 is equipped with a buckle structure 2 around the perimeter, there is a certain distance between the bottom of the housing 1 and the bottom of the original dosing tank, which facilitates the smooth flow of flocculant powder into the dosing system. The entire dosing process is a fully enclosed operation, which successfully avoids contact between the operator and the flocculant powder, prevents the operator from inhaling the flocculant powder, minimizes the corrosion and harm of the flocculant powder to the operator, and effectively prevents the flocculant powder from scattering in the surrounding operating environment, thus achieving the purpose of closed, safe and environmentally friendly dosing.

[0032] This invention relates to a closed-loop flocculant dosing device for wastewater treatment, suitable for flocculant dosing in wastewater systems. After applying this device, dosing time is significantly reduced, from 20 minutes using the traditional method to 5 minutes. Based on approximately 3 dosings per day, this amounts to 365 × 3 = 1095 dosings per year. Since each dosing session saves 15 minutes, the reduction in dosing time throughout the year is substantial.

[0033] Furthermore, when using the dosing device of this application to add flocculants, the dosing process is a fully enclosed operation, which can successfully prevent the inhalation of powdered flocculants into the human body, greatly reduce the irritation of flocculant powder to the nasal cavity and throat and its contact with the eyes and skin, successfully avoid irreversible eye damage caused by eye corrosion, and prevent the occurrence of skin burns and allergies. Obviously, the effective improvement of operating conditions and environment during the dosing process means that operators no longer need to wear bulky gas masks and goggles, improving work efficiency and enhancing work comfort.

[0034] Meanwhile, since the entire package of flocculant is directly added into the tank 1, it can effectively prevent the powdered flocculant from scattering around the tank during the dosing process, thus avoiding environmental pollution and achieving a closed, safe, and environmentally friendly dosing effect.

[0035] Therefore, the dosing device of this application has good practical application effect. Compared with the traditional dosing method, the dosing safety rate can reach 100%. Moreover, due to its characteristics of being airtight, environmentally friendly, and protecting personal safety during the dosing process, it has been well received by the majority of operators and has broad promotion value.

[0036] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical applications, or technical improvements to the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
