Abstract
Description
Technical Field
[0001] This utility model relates to the field of odor-proof floor drain technology, specifically a petrochemical-grade odor-proof triple-effect floor drain. Background Technology
[0002] A floor drain is a drainage accessory installed on the ground or in low-lying areas to collect and discharge sewage and wastewater, while preventing gases, odors, and pests from entering the room or specific spaces from the pipes. It is widely used in various scenarios such as residential buildings, commercial buildings, and industrial plants. Its core functions include two main dimensions: drainage and protection. In terms of drainage, a specific inlet structure collects surface water and guides it through internal channels into the drainage pipe, ensuring rapid drainage and preventing stagnation. In terms of protection, mainstream floor drains use "water seal" or "mechanical seal" technology to prevent foul gases, mosquitoes, cockroaches, etc., from entering the room. Some industrial floor drains also incorporate special protective designs such as anti-clogging, anti-corrosion, and explosion-proof features to meet the safety requirements of different scenarios.
[0003] In existing technologies, some specifications are incompatible with the on-site drainage pipes, causing sewage discharge blockage or splashing. If the drain pipe diameter is larger than the drainage pipe, the sudden narrowing of the flow cross-section causes a sudden increase in flow velocity and a sudden drop in pressure. Solid particles settle due to inertia, and highly viscous oil adheres to the pipe wall, forming a blockage. If the drain pipe diameter is small, the outflow velocity is insufficient, and the drag force of the water flow is difficult to balance the gravity of the particles, leading to particle deposition. If the sealing is poor, it will cause odor to overflow, as the sealing structure cannot block the diffusion of malodorous gases in the sewage pipe, involving technical problems such as water seal failure and leakage from structural gaps. From the perspective of the water seal principle, a qualified drain relies on the water accumulation in the trap to form a liquid seal, using the barrier property of water to block gas flow. If the water seal height is insufficient, or if the petrochemical wastewater contains highly volatile components, accelerating the evaporation of water in the water seal will cause the liquid seal to break, and gas will break through the water seal gap and overflow. If there is no waste gas treatment function, there is a safety hazard. The highly volatile organic compounds and toxic gases contained in petrochemical wastewater will continuously diffuse into the room or equipment area through the drain due to the concentration difference between the inside of the pipe and the outside. If the environment is poorly ventilated, gases tend to accumulate in low-lying areas. When the concentration reaches the explosive limit, it can cause a combustion and explosion accident if it comes into contact with an open flame or an electric spark, according to the three elements of combustion. At the same time, some gases are toxic, and when the concentration exceeds the standard, they can enter the human body through respiration, leading to poisoning. Utility Model Content
[0004] The purpose of this utility model is to provide a petrochemical-grade, odor-proof, three-effect floor drain to solve the problems mentioned in the background art, such as the incompatibility of some specifications of existing floor drains with the on-site drainage pipes, resulting in sewage discharge blockage or splashing; poor sealing, resulting in odor overflow; and lack of waste gas treatment function, posing safety hazards.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a petrochemical-grade odor-proof triple-effect floor drain, including a panel, a floor drain mounting base detachably mounted on the panel, a drainage component mounted on the floor drain mounting base, a waste gas treatment component mounted on the floor drain mounting base, a main drain pipe fixedly connected to the floor drain mounting base, and a multi-channel drain pipe mounted on the main drain pipe. Sewage flows along the multi-channel drain pipe in a preset direction, and waste gas in the sewer enters the interior of the waste gas treatment component through the exhaust hole at the bottom of the waste gas treatment component.
[0006] Based on the preferred embodiment of this technical solution, multiple multi-channel drainage pipes are provided, and all multi-channel drainage pipes are installed on the main drainage pipe.
[0007] Based on the preferred embodiment of this technical solution, the multi-channel drainage pipe is connected to the main drainage pipe.
[0008] According to the preferred embodiment of this technical solution, the drainage component includes a multi-channel drain outlet opened on the floor drain mounting base, a main drain pipe connecting pipe installed at the bottom of the multi-channel drain outlet, and an odor-proof valve installed inside the main drain pipe connecting pipe. The main drain pipe and the main drain pipe connecting pipe are installed on the multi-channel drain outlet.
[0009] Based on the preferred embodiment of this technical solution, the exhaust gas treatment component includes an exhaust gas treatment cylinder fixedly connected to the floor drain mounting base, an exhaust gas treatment mounting shell detachably installed on the exhaust gas treatment cylinder, a rainproof louver with a fire-resistant mesh opened on the side of the exhaust gas treatment mounting shell, and a deodorizing bag detachably installed inside the exhaust gas treatment cylinder. The exhaust gas inside the sewer enters the interior of the exhaust gas treatment cylinder through the exhaust hole at the bottom of the exhaust gas treatment cylinder.
[0010] Based on the preferred embodiment of this technical solution, the exhaust gas treatment mounting shell is equipped with rainproof louvers with fire-resistant mesh, and the rainproof louvers with fire-resistant mesh are evenly distributed on the side of the exhaust gas treatment mounting shell.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. Utilizing a multi-channel drainage pipe design, it can precisely match multiple drainage devices on petrochemical sites. Through the tight connection of the multi-channel drainage pipes and flexible hoses, effective direct discharge of wastewater is achieved, avoiding sludge buildup caused by blockages at a single inlet, and adapting to the drainage needs of different devices. Simultaneously, the detachable floor drain mounting base allows for flexible adjustment to adapt to various ground construction scenarios. The multi-channel drainage pipes are tightly connected to the site devices via flexible hose threads. Combined with the characteristic of water flowing directly along the inner wall of the pipes, it completely prevents wastewater overflow and splashing, reduces the corrosion of the ground and equipment by toxic and harmful components, and lowers environmental and personnel safety hazards, providing outstanding safety protection. The exhaust gas treatment device utilizes the air pressure difference inside and outside the drainage pipes to adsorb and decompose harmful exhaust gases generated from sewers and stagnant sewage through deodorizing bags. The gases are then discharged in compliance with standards through rainproof louvers with flame-retardant mesh, controlling exhaust gas pollution at its source and reducing the impact on the working environment and personnel health.
[0012] Lower maintenance costs: The detachable structure of the floor drain mounting base makes it easier to inspect and replace the drainage components and exhaust gas treatment components without disassembling the entire device, greatly reducing maintenance difficulty and time costs, and ensuring long-term stable operation of the equipment.
[0013] 2. Two drainage outlets are formed by connecting a multi-channel drain outlet to a floor drain. The multi-channel drain outlet connects to a multi-channel drain pipe to collect wastewater from the equipment. The floor drain connection is suitable for rainwater and wastewater discharge from the ground. Both operate independently yet complement each other, ensuring smooth direct discharge of wastewater from the equipment without interfering with surface drainage. This avoids the accumulation caused by functional conflicts between single drain outlets. Both the floor drain pipe and the main drain pipe are equipped with odor-proof valves. These dual valves work together to prevent the backflow of odorous gases from the sewer system, completely solving the pipe odor problem. Simultaneously, the one-way flow structure of the odor-proof valves effectively prevents wastewater backflow, avoiding backflow of wastewater from the ground and equipment, thus reducing safety risks. Depending on the actual site conditions, it is possible to choose to install only the multi-channel drain outlet or both the multi-channel drain outlet and the floor drain connection.
[0014] 3. The exhaust gas treatment cylinder, as a specialized exhaust gas treatment device, utilizes the pressure difference between the inside and outside of the drainage pipe to efficiently guide harmful exhaust gases generated by sewers and stagnant sewage into the cylinder. After being adsorbed and decomposed by the deodorizing bag, the gases are discharged in compliance with standards through rainproof louvers with flame-retardant mesh. This addresses exhaust gas pollution at its source, reducing the impact on the working environment and personnel health. This component can dynamically balance the air pressure inside and outside the drain. When negative or positive pressure impacts occur during drainage, the exhaust gas treatment cylinder uses airflow regulation to offset pressure fluctuations, avoiding drainage obstruction caused by pressure differences. Combined with the guiding effect of the dual drain outlets, it further ensures smooth discharge of sewage and rainwater. It reduces the risk of explosion caused by the accumulation of toxic gases through exhaust gas purification, and prevents sewage leakage caused by pipe rupture due to pressure impact through air pressure balance. The detachable exhaust gas treatment housing facilitates regular maintenance, comprehensively improving the operational safety of the equipment. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example 1: Please see Figures 1-6This utility model provides a petrochemical-grade, odor-proof, three-function floor drain: It includes a panel 1, and is characterized by further including a floor drain mounting base 2 detachably mounted on the panel 1, a drainage component mounted on the floor drain mounting base 2, a waste gas treatment component mounted on the floor drain mounting base 2, a main drain pipe 701 fixedly connected to the floor drain mounting base 2, and a multi-channel drain pipe 702 mounted on the main drain pipe 701. Wastewater flows along the multi-channel drain pipe 702 in a preset direction, and waste gas in the sewer enters the interior of the waste gas treatment component through the vent at the bottom of the waste gas treatment component. The detachable floor drain mounting base 2... This design not only facilitates the later inspection and replacement of internal components of the floor drain, reducing maintenance difficulty and costs, but also allows for flexible adjustment of the type according to on-site installation needs, adapting to different ground construction scenarios. The 701 drain pipe design can simultaneously handle the sewage discharge from multiple on-site devices, improving drainage efficiency and avoiding sewage accumulation caused by congestion at a single inlet. The 701 drain pipe can be made of 2mm stainless steel. The on-site floor drain size is generally DN50 or DN100, while the on-site drainage device size is more varied, generally DN20 / DN25 / DN50 / DN80 / DN100 / DN200, etc.
[0019] Please see Figures 2-3 A further solution based on this embodiment is as follows: multiple multi-channel drain pipes 702 are provided, and all multiple multi-channel drain pipes 702 are installed on the main drain pipe 701. By installing multiple multi-channel drain pipes 702 on the main drain pipe 701, wastewater from the field device from different directions can be evenly and stably discharged into the main drain pipe 701, avoiding excessive water flow impact caused by unilateral water inflow, reducing wear on the inner wall of the pipe, and extending the service life of the pipe.
[0020] Please see Figures 2-3 A further solution based on this embodiment is as follows: multiple multi-channel drainage pipes 702 are connected to a main drainage pipe 701. By uniformly connecting multiple multi-channel drainage pipes 702 to the main drainage pipe 701, and utilizing the diversion and confluence characteristics of the structure, the sewage from the multiple drainage pipes forms a gentle flow when it flows into the main drainage pipe 701, reducing the collision between water flows, lowering water flow noise, and improving the on-site working environment.
[0021] Example 2: Please see Figures 2-6A further solution based on this embodiment is as follows: the drainage component includes a multi-channel drain outlet opened on the floor drain mounting base, a main drain pipe connecting pipe installed at the bottom of the multi-channel drain outlet, and an odor-proof valve installed inside the main drain pipe connecting pipe. The main drain pipe is installed on the multi-channel drain outlet. By setting the multi-channel drain outlet and the main drain pipe connecting pipe in the drainage component, wastewater of different properties in the petrochemical scenario can be diverted for treatment. With the odor-proof valve inside the main drain pipe connecting pipe, it can automatically open when draining and close tightly when there is no water, effectively blocking the upward diffusion of sewer exhaust gas through the main drain pipe connecting pipe and the multi-channel drain outlet, while preventing sewage backflow. Furthermore, the direct connection between the main drain pipe connecting pipe and the multi-channel drain outlet further ensures smooth drainage and takes into account odor prevention and sealing, fully meeting the high requirements of hygiene and safety in the petrochemical environment.
[0022] Please see Figures 5-6 A further solution based on this embodiment is as follows: the exhaust gas treatment component includes an exhaust gas treatment cylinder 901 fixedly connected to the floor drain mounting base 2, an exhaust gas treatment mounting shell 902 detachably installed on the exhaust gas treatment cylinder 901, a rainproof louver 903 with a fire-resistant mesh opened on the side of the exhaust gas treatment mounting shell 902, and a deodorizing bag 904 detachably installed inside the exhaust gas treatment cylinder 901. The exhaust gas inside the sewer enters the interior of the exhaust gas treatment cylinder 901 through the exhaust hole at the bottom of the exhaust gas treatment cylinder 901. By utilizing the pressure difference between the inside and outside of the drainage pipe, the exhaust gas inside the sewer can be concentrated and enter the exhaust gas treatment cylinder 901. After adsorption and decomposition by the internal deodorizing bag 904, the malodorous components and some harmful gases such as hydrogen sulfide and hydrocarbon gases in the exhaust gas are effectively removed, reducing the pollution of the exhaust gas to the on-site environment, protecting the respiratory health of the workers, and avoiding safety accidents caused by toxic gases. The detachable exhaust gas treatment installation shell 902 makes it easy to replace the deodorizing bag 904 later without disassembling the entire exhaust gas treatment cylinder 901, reducing maintenance difficulty and cost. The exhaust device inside the exhaust gas treatment cylinder 901 is made of the thinnest stainless steel plate.
[0023] Please see Figures 5-6A further solution based on this embodiment is as follows: Several rainproof louvers 903 with fire-resistant mesh are provided on the rainproof louvers 903 with fire-resistant mesh, and these rainproof louvers 903 with fire-resistant mesh are evenly distributed on the side of the exhaust gas treatment housing 902. By evenly distributing several rainproof louvers 903 with fire-resistant mesh on the side of the exhaust gas treatment housing 902, the exhaust gas discharge area can be increased, allowing the exhaust gas treated by the deodorization bag 904 to be discharged quickly and evenly, preventing exhaust gas from stagnating inside the exhaust gas treatment cylinder 901 and improving exhaust gas treatment efficiency. The evenly distributed rainproof louvers with fire-resistant mesh ensure consistent ventilation in all parts of the exhaust gas treatment housing 902, preventing exhaust gas accumulation due to poor local ventilation and further reducing the risk of exhaust gas overflow.
[0024] Working Principle: Wastewater from the on-site device is tightly connected to a multi-channel drain pipe 702 via a flexible hose. The multi-channel drain pipe 702 connects to a main drain pipe 701. This connection structure allows wastewater from different directions to flow gently and smoothly, preventing water collisions and impurity deposition. The wastewater then flows through the multi-channel drain outlet 801 into the main drain pipe until it is discharged. Ground wastewater undergoes initial filtration through the drain hole of the drain cover 807, intercepting large particles such as metal blocks and plastic fragments. The drain hole also buffers the water flow to prevent splashing. The filtered wastewater flows into the drain connection 802 and the drain pipe 804. Because the outer side of the drain body 803 is tightly fitted to the inner wall of the drain pipe 804, the wastewater flows smoothly down the inner wall of the pipe, reducing resistance and sedimentation. The odor-proof valve 806 inside the drain pipe 804 and the main drain pipe 805 forms a double barrier, preventing the backflow of malodorous gases from the sewer through a water seal or mechanical seal. Meanwhile, the drain body 803 uses its own gravity to ensure a tight fit between the limiting ring and the drain mounting base 2, forming multiple seals with the pipe fitting structure to prevent sewage leakage and gas overflow. Harmful exhaust gases generated by sewer and sewage retention enter the exhaust gas treatment cylinder 901 through the pressure difference between the inside and outside of the drainage pipe, where the internal deodorization bag 904 adsorbs and decomposes pollutants such as hydrogen sulfide and hydrocarbons. The treated exhaust gas is discharged through rainproof louvers 903 with fire-resistant mesh evenly distributed on the side of the exhaust gas treatment mounting shell 902. The rainproof louvers 903 with fire-resistant mesh not only ensure exhaust efficiency but also prevent fire, rainwater, and dust from entering, ensuring stable operation of the components around the clock.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
