Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment equipment, in particular to a low-energy-consumption silane wastewater treatment device. Background Art

[0002] Silane wastewater primarily originates from the semiconductor manufacturing industry, photovoltaic industry, surface treatment industry, and chemical synthesis field. Within these industries, silane is widely used in processes such as thin film deposition, silicon wafer cleaning, silane cracking, and silane combustion. Consequently, the wastewater generated by these processes contains high concentrations of silicon, organic matter, acids, and alkalis. Furthermore, this wastewater is toxic, corrosive, and difficult to degrade.

[0003] Silane wastewater treatment is a complex and important environmental project. It primarily targets wastewater generated during silane production and use, ensuring it meets discharge standards or is recycled. The silane wastewater treatment process primarily includes pretreatment, chemical treatment, biological treatment, and advanced treatment, forming a systematic and efficient process. Typically, silane wastewater treatment can be performed using customized equipment.

[0004] Based on this, Chinese patent CN218202469U discloses a device for treating silane wastewater, comprising a reaction tank, the bottom outer wall of which is hingedly connected to a base plate, the top outer wall of which is fixedly connected to a bellows, the other end of which is connected to the bottom end of the reaction tank, a hinged seat provided on the bottom outer wall of the base plate, and a second pneumatic telescopic rod connected to the base plate via the hinged seat, a second water pipe fixedly connected to one inner wall of the reaction tank, and a water pipe fixedly connected to the other inner wall of the reaction tank, the second water pipe being higher than the water pipe, and a solenoid valve provided on the inner wall of the water pipe, a water level monitor provided on the inner wall of the reaction tank, a base fixedly connected to one outer wall of the reaction tank, and a connection seat fixedly connected to one inner wall of the base. The device for treating silane wastewater disclosed in this patent has the effect of preventing oil from clogging subsequent filtration devices during unified filtration, thereby increasing the service life of the device.

[0005] However, the silane wastewater treatment device disclosed above still has the technical problem of being unable to perform temperature control on the wastewater process. Specifically, silane wastewater treatment is a comprehensive environmental protection project, which needs to be reasonably designed and optimized according to the characteristics of the wastewater and environmental protection requirements. By combining a variety of treatment methods such as physical, chemical, and biological methods, and selecting appropriate treatment agents and process equipment, effective treatment and recycling of silane wastewater can be achieved. This not only helps to reduce environmental pollution, but also achieves the conservation and recycling of water resources, which has important social and economic significance. Although the existing patent discloses a wastewater treatment device that can achieve oil-water separation, more specifically, it discloses a silane wastewater treatment device that can increase the potential energy of the water flow, so that the oil located on the inside can enter the water pipe with the water flow, so that most of the oil can be separated from the wastewater for additional treatment, thereby avoiding the blockage of subsequent filtering devices caused by oil during unified filtration, thereby increasing the service life of the device. However, the treatment of silane wastewater inevitably involves steps such as neutralization reactions or chemical precipitation. For example, neutralization is used to adjust the pH of the wastewater to a neutral range to avoid environmental damage. Acidic substances are used to neutralize silicates in the wastewater to form silicic acid precipitates, which are then separated into solids and liquids using equipment such as sedimentation tanks and filter presses. This process requires strict control of pH and reaction time to ensure complete and stable precipitation. Alternatively, for residual organic matter and some silanols, advanced oxidation technologies can be used for deep treatment, using strong oxidants to oxidize and decompose them into carbon dioxide and water. These treatments typically require temperature control of the wastewater treatment system to accelerate the completion of the reaction, and they also need to meet low energy consumption requirements.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0025] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense.

[0028] Please also refer to Figures 1 to 4 The utility model discloses a low-energy silane wastewater treatment device comprising: a support frame 1, a conical tank bottom 2, a tank body 3, an inlet pipe 4, an outlet pipe 5, a stirring power mechanism 6, a stirring structure 7 and a heat exchange structure 8; the support frame 1 is connected to the conical tank bottom 2, and the tank body 3 is connected to the conical tank bottom 2; the inlet pipe 4 is connected to the tank body 3, and the outlet pipe 5 is connected to the conical tank bottom 2; the stirring power mechanism 6 is arranged on the tank body 3, and the stirring structure 7 is arranged in the tank body 3, and the stirring power mechanism 6 is drivingly connected to the stirring structure 7; the heat exchange structure 8 is respectively coiled and connected to the conical tank bottom 2 and the outer wall of the tank body 3.

[0029] Specifically, when the low-energy silane wastewater treatment device of the present invention is in operation, wastewater such as silane to be treated flows from the inlet pipe 4 into the tank body 3 and the conical tank bottom 2. Thereafter, neutralization raw materials or other types of reactants to be added can flow in from the inlet pipe 4 or from the top of the tank body 3. Then, the stirring power mechanism 6 is activated upon receiving power, driving the stirring structure 7 to stir and rotate within the tank body 3 and the conical tank bottom 2. This allows the added materials to fully contact and dissolve with the previously introduced silane wastewater. At the same time, the heat exchange structure 8 exchanges heat with the tank body 3 and the conical tank bottom 2 to increase or decrease the internal temperature of the tank body 3 or the conical tank bottom 2. Because the heat exchange structure 8 is connected to an external cold or heat source, heat can be transferred between the conical tank bottom 2, the tank body 3, and the heat exchange structure 8, thereby achieving a temperature increase or decrease effect through heat exchange. This allows for low-energy temperature control during the silane wastewater treatment process. Finally, the treated silane wastewater can flow out of the outlet pipe 5.

[0030] Furthermore, the tank body 3 comprises a main body 301, a top cover 302, a movable opening and closing portion 303, a support frame 304, and a sensor module 305. The main body 301 is connected to the conical tank bottom 2, and the top cover 302 is connected to the top of the main body 301. The movable opening and closing portion 303 is opened and closed within the top cover 302, and the support frame 304 is fixedly connected to the top of the top cover 302. The sensor module 305 is disposed within the main body 301 and connected below the top cover 302. Specifically, the sensor module 305 can include parameters such as temperature and pressure for measuring, so as to facilitate monitoring of the progress of the silane treatment.

[0031] Furthermore, the stirring power mechanism 6 has a reducer connecting seat 601, a reducer structure 602 and an electric motor 603; the reducer connecting seat 601 is connected to the support frame 304, the reducer structure 602 is arranged on the reducer connecting seat 601, and the electric motor 603 is power-connected to the reducer structure 602.

[0032] Furthermore, the stirring structure 7 has a top bearing structure 701, a bottom bearing structure 702, a main shaft structure 703, a frame stirring structure 704 and a spiral stirring structure 705; the top bearing structure 701 is connected to the top cover 302, and the bottom bearing structure 702 is connected to the bottom of the conical tank bottom 2; the upper end of the main shaft structure 703 is dynamically connected to the reducer structure 602, and the main shaft structure 703 is respectively connected to the top bearing structure 701 and the bottom bearing structure 702; the frame stirring structure 704 is arranged in the tank body 3, and the frame stirring structure 704 is connected to the upper part of the main shaft structure 703; the spiral stirring structure 705 is arranged in the conical tank bottom 2, and the spiral stirring structure 705 is connected to the lower part of the main shaft structure 703.

[0033] Specifically, after the motor 603 is powered on and started, it can transmit the rotational power to the reducer structure 602. After the reducer structure 602 reduces the rotational speed and increases the rotational torque, the rotational power is then transmitted to the upper end of the main shaft structure 703. Thus, the main shaft structure 703 can be driven to rotate. Because the main shaft structure 703 needs to pass through the top cover 302, extend into the tank body 3 and the conical tank bottom 2, and connect to the bottom of the conical tank bottom 2, the top bearing structure 701 connects the top cover 302 and the upper part of the main shaft structure 703, respectively, and the bottom bearing structure 702 connects the bottom of the conical tank bottom 2 and the lower end of the main shaft structure 703, respectively. When the main shaft structure 703 rotates, it can simultaneously drive the frame stirring structure 704 and the spiral stirring structure 705 to rotate simultaneously; the spiral stirring structure 705 can re-stir and lift the wastewater and materials deposited on the conical tank bottom 2, so that the incompletely dissolved or incompletely broken parts can re-enter the cavity of the tank body 3; the frame stirring structure 704 is a frame-shaped stirring structure, which can stir and break up the materials in the tank body 3. In addition, the conical shape of the conical tank bottom 2 can not only facilitate the gathering of fluid and its outflow from the outlet pipe 5, but also facilitate the re-lifting of fluid to form a vortex and flow back into the tank body 3.

[0034] Furthermore, the heat exchange structure 8 comprises an upper coil structure 801 and a lower coil structure 802. The upper coil structure 801 is coiled around the outer wall of the tank body 3, while the lower coil structure 802 is coiled around the outer wall of the conical tank bottom 2. The upper coil structure 801 and the lower coil structure 802 are connected. Specifically, external fluid can enter through the reserved nozzle end of the upper coil structure 801, flow around the outer wall of the tank body 3 several times, flow into the lower coil structure 802, and then flow around the outer wall of the conical tank bottom 2 several times before exiting through the reserved nozzle end of the lower coil structure 802. This allows the external fluid to fully exchange heat with the tank body 3 or the conical tank bottom 2. For example, hot water flowing in from the outside can transfer heat to the inner cavities of both to achieve temperature control; while cooling water flowing in from the outside can remove heat from the inner cavities of both to achieve temperature control.

[0035] Furthermore, a climbing ladder 9 is provided on the outer side of the conical tank bottom 2 and the tank body 3; the climbing ladder 9 is connected to the top cover 302 and the support frame 304. Specifically, an operator can climb to the top of the tank body 3 via the climbing ladder 9 to open or close the movable opening and closing portion 303, thereby enabling monitoring, observation, cleaning, and other operations within the tank body 3 or the conical tank bottom 2.

[0036] To sum up, the utility model is a low-energy silane wastewater treatment device which is respectively provided with a supporting frame 1, a conical tank bottom 2, a tank body 3, an inlet pipe 4, an outlet pipe 5, a stirring power mechanism 6, a stirring structure 7 and a heat exchange structure 8; the supporting frame 1 is connected to the conical tank bottom 2, and the tank body 3 is connected to the conical tank bottom 2; the inlet pipe 4 is connected to the tank body 3, and the outlet pipe 5 is connected to the conical tank bottom 2; the stirring power mechanism 6 is arranged on the tank body 3, and the stirring structure 7 is arranged in the tank body 3, and the stirring power mechanism 6 is driven and connected to the stirring structure 7; the heat exchange structure 8 is respectively coiled and connected to the conical tank bottom 2 and the outer wall of the tank body 3. The heat exchange structure 8 exchanges heat with the tank body 3 and the conical tank bottom 2 to increase or decrease the internal temperature of the tank body 3 or the conical tank bottom 2. Since the heat exchange structure 8 is connected to an external cold source or heat source, heat can be transferred between the conical tank bottom 2, the tank body 3 and the heat exchange structure 8. Thus, the effect of heating or cooling can be achieved by heat exchange. Thus, the temperature of the silane wastewater treatment process can be controlled with low energy consumption without the need to set up a heating structure or other device in the tank. Therefore, the low-energy silane wastewater treatment device of the present invention solves the technical problem of how to conveniently control the system temperature of the silane wastewater treatment device.

[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
