Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a portable ship waste gas treatment device. Background Technology

[0002] Ship exhaust gas treatment is an environmental protection technology closely related to human life. Exhaust gas treatment mainly targets the treatment and control of sulfur oxide emissions. By using low-sulfur fuel oil or installing treatment towers, the problem of sulfur oxide pollution can be solved, which falls under the field of air pollution control.

[0003] Chinese Patent No. CN205586728U discloses a waste gas treatment and purification device, including an airtight door, a dust collector, and a treatment box. The dust collector is installed on the left side of the upper surface of the base, and the airtight door is installed on the left side of the dust collector. An air inlet and a waste gas particle detection instrument are provided on the top of the dust collector. The treatment box is installed on the right side of the upper surface of the base. A treatment agent storage bottle, an alarm device, and an exhaust port are provided on the top of the treatment box. A servo motor is provided on the left side of the operating turntable, and a detection device is provided on the inner wall of the treatment box.

[0004] This invention utilizes a stirrer that rotates at high speed driven by a servo motor, allowing the exhaust gas to come into more thorough contact with the treatment agent, resulting in better treatment. The alarm device prompts staff to add treatment agent, saving a significant amount of manpower and improving work efficiency. However, the device does not monitor the treated gas at the outlet. Considering that incompletely treated gas will continue to be discharged after the treatment agent is depleted, causing environmental pollution, a portable ship exhaust gas treatment device is proposed.

[0005] To address the shortcomings of existing technologies, this utility model provides a portable ship exhaust gas treatment device, which has the advantages of high flexibility and practicality, and solves the problem of incomplete gas treatment and environmental pollution caused by traditional exhaust gas treatment and purification devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable ship exhaust gas treatment device, including an air inlet pipe, an air inlet box provided on the side of the air inlet pipe, a preliminary measurement component for extracting exhaust gas provided inside the air inlet box, an air storage box fixed above the air inlet box, an air outlet pipe fixed on the top of the air storage box, and a valve assembly provided inside the air outlet pipe. The initial testing component includes a rotary motor fixed to the bottom wall of the air intake box, a rotating cylinder fixed to the outside of the output shaft of the rotary motor, several fixing rods fixedly installed on the inner wall of the air intake box, an exhaust gas monitoring module fixed to the side of the fixing rods, a gearbox fixed to the opposite side of the fixing rods, a transmission rod rotatably connected inside the gearbox, a support rod rotatably connected to the top of the output shaft of the rotary motor, a rotating rod rotatably connected to the top of the support rod, and a guide cylinder fixed to the outside of the rotating rod. The valve assembly includes a fixing plate fixed to the bottom of the vent pipe, an electric push rod for controlling the opening and closing of the vent pipe fixed to the top of the fixing plate, a sealing plate for filling the interior of the vent pipe fixed to the top of the electric push rod, a plurality of movable rods fixed to the outside of the sealing plate, and a sealing plug fixed to the top of the movable rods.

[0007] Furthermore, the top of the air inlet box is inserted into the interior of the air storage box, and the top surface of the air inlet box located inside the air storage box has several air outlet holes. Several evenly distributed gas monitoring sensors are fixed on the inner side wall of the air storage box.

[0008] Furthermore, a spiral blade is fixed to the outer side of the rotating cylinder, the bottom of the rotating cylinder is rotatably connected to the air intake box, the output shaft of the rotating motor passes through the bottom wall of the gearbox to the inside of the gearbox, and a drive gear is fixed to the outer side of the output shaft inside the gearbox.

[0009] Furthermore, the bottom of the rotating rod is embedded inside the gearbox and is rotatably connected to the gearbox. A driven gear is fixed to the outside of the rotating rod inside the gearbox, and the top of the rotating rod is rotatably connected to the air intake box.

[0010] Furthermore, two transmission gears of different sizes are fixed to the outer sides of the upper and lower ends of the transmission rod. The two transmission gears mesh with the driving gear and the driven gear, respectively. Fan blades for exhaust are fixed to the outer side of the guide tube.

[0011] Furthermore, the bottom outer side of the air outlet pipe is provided with several annularly distributed air inlets and outlets, and the movable rod is an L-shaped structure consisting of a horizontal rod and a vertical rod. The horizontal rod passes through the air inlet and outlet laterally and is slidably connected to the inner wall of the air inlet and outlet slot.

[0012] Furthermore, a sealing gasket for filling the cavity of the vent pipe is fixed to the top of the sealing plate, and the side of the sealing plate is slidably connected to the cavity wall of the vent pipe.

[0013] Furthermore, the top of the gas storage tank is provided with several exhaust holes, the vertical rod of the movable rod passes vertically through the exhaust holes to the outside of the gas storage tank, and the size of the sealing plug is larger than the exhaust holes.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This portable marine exhaust gas treatment device uses a rotary motor to drive a rotating cylinder to rotate. The rotating spiral blades on the outside of the rotating cylinder send the exhaust gas from the bottom of the intake box to the top of the intake box. After the exhaust gas is initially monitored by the exhaust gas detection module, the rotation of the fan blades inside the guide tube sends the exhaust gas from the intake box into the storage box. When the data exceeds the standard, the sealing plug inside the valve assembly blocks the exhaust hole at the top of the storage box, and at the same time the sealing plate opens, so that the exhaust gas can return to the purification device along the exhaust pipe for secondary treatment.

[0015] 2. This portable ship exhaust gas treatment device monitors the gas in detail through a gas monitoring module. The data meets the established standards. The sealing plate inside the valve assembly seals the cavity of the gas storage pipe. At the same time, the sealing plug releases the seal on the exhaust hole at the top of the gas storage tank during movement. The exhaust gas inside the gas storage tank can be smoothly discharged directly into the external environment through the exhaust hole, thereby avoiding the pollution and damage to the environment caused by the direct discharge of incompletely treated gas into the environment.

[0018] 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.

[0019] Please see Figures 1 to 2 A portable ship exhaust gas treatment device in this embodiment includes an air inlet pipe 1, an air inlet box 2 on the side of the air inlet pipe 1, a preliminary measurement component 3 for extracting exhaust gas inside the air inlet box 2, an air storage box 4 fixed above the air inlet box 2, an air outlet pipe 5 fixed on the top of the air storage box 4, and a valve assembly 6 inside the air outlet pipe 5.

[0020] By connecting the air inlet pipe 1 and the exhaust pipe, the air inlet box 2 initially collects the exhaust gas. The initial measurement component 3 improves the flow of the exhaust gas while performing preliminary monitoring. After monitoring, the flow rate of the internal gas is adjusted as needed. The exhaust pipe 5 is connected to the purification device and is responsible for re-introducing the gas that does not meet the standards after monitoring into the purification device for treatment. The valve component 6 controls the flow path of the exhaust gas. The device can be installed at the outlet of the ship's exhaust gas emission treatment pipeline according to actual usage needs.

[0021] It should be noted that the device can be installed and disassembled according to actual usage needs. It can be installed and fixed by bolts and other means, and the pipes can be connected to each other to achieve portability and installation. At the same time, it needs to be used in conjunction with an exhaust gas treatment device, which treats air pollutants including but not limited to carbon dioxide, nitrogen oxides, sulfur oxides, and particulate matter to reduce pollution. This technology is already quite mature and will not be elaborated on here.

[0022] Please refer to it again. Figure 2 , and see Figures 3 to 4 To improve the flowability of exhaust gas and enhance monitoring accuracy, the initial measurement component 3 in this embodiment includes a rotary motor 31 fixed to the bottom wall of the air intake box 2. A rotating cylinder 32 is fixed to the outside of the output shaft of the rotary motor 31. Several fixing rods are fixedly installed on the inner side wall of the air intake box 2. An exhaust gas monitoring module 33 is fixed to the side of the fixing rods. A gearbox 34 is fixed to the opposite side of the fixing rods. A transmission rod 35 is rotatably connected inside the gearbox 34. A support rod 36 is rotatably connected to the top of the output shaft of the rotary motor 31. A rotating rod 37 is rotatably connected to the top of the support rod 36. A guide cylinder 38 is fixed to the outside of the rotating rod 37.

[0023] In this embodiment, the top of the air inlet box 2 is inserted into the interior of the air storage box 4, and the top surface of the air inlet box 2 located inside the air storage box 4 is provided with several air outlet holes. Several evenly distributed gas monitoring modules 41 are fixed on the inner side wall of the air storage box 4.

[0024] It should be noted that the gas monitoring module 41 includes, but is not limited to, sensors using technologies such as electrochemical, infrared absorption, and laser scattering.

[0025] In this embodiment, a spiral blade is fixed to the outer side of the rotating cylinder 32. The bottom of the rotating cylinder 32 is rotatably connected to the air intake box 2. The rotating motor 31 drives the rotating cylinder 32 to rotate, so that the spiral blade on the outer side of the rotating cylinder 32 sends the exhaust gas located at the bottom to the interior of the air storage box 4. The output shaft of the rotating motor 31 passes through the bottom wall of the gearbox 34 to the interior of the gearbox 34, and a drive gear is fixed to the outer side of the output shaft located inside the gearbox 34. The bottom of the rotating rod 37 is embedded in the interior of the gearbox 34 and is rotatably connected to the gearbox 34. A driven gear is fixed to the outer side of the rotating rod 37 located inside the gearbox 34. The top of the rotating rod 37 is rotatably connected to the air intake box 2. Two transmission gears of different sizes are fixed to the outer sides of the upper and lower ends of the transmission rod 35. The two transmission gears mesh with the drive gear and the driven gear, respectively. A fan blade 381 for exhaust is fixed to the outer side of the guide cylinder 38.

[0026] By setting the transmission rod 35 to be connected to the rotary motor 31 and the rotary rod 37 respectively, the rotary motor 31 can drive the rotary rod 37 and the rotary cylinder 32 to rotate at the same time, while the rotation speeds of the rotary rod 37 and the rotary cylinder 32 are different.

[0027] It should be noted that the size ratio of the two transmission gears can be controlled according to actual usage needs. By matching appropriate transmission gears, drive gears, and transmission gears, the speed difference between the rotating cylinder 32 and the rotating rod 37 can be controlled, thereby adjusting the flow rate of the exhaust gas.

[0028] Please refer to it again. Figure 2 and see Figure 5 In order to control the flow path of the exhaust gas and prevent untreated exhaust gas from flowing into the external environment, the valve assembly 6 in this embodiment includes a fixing plate 61 fixed to the bottom of the exhaust pipe 5. An electric push rod 62 for controlling the opening and closing of the exhaust pipe 5 is fixed to the top of the fixing plate 61. A sealing plate 63 for filling the interior of the exhaust pipe 5 is fixed to the top of the electric push rod 62. Several movable rods 64 are fixed to the outside of the sealing plate 63. A sealing plug 65 is fixed to the top of the movable rods 64.

[0029] In this embodiment, the bottom outer side of the air outlet pipe 5 is provided with several annularly distributed air inlets and outlets. The movable rod 64 is an L-shaped structure divided into a horizontal rod and a vertical rod. The horizontal rod passes through the air inlet and outlet and is slidably connected to the inner wall of the air inlet and outlet slot.

[0030] In this embodiment, the top of the sealing plate 63 is fixed with a sealing gasket that fills the cavity of the air outlet pipe 5, and the side of the sealing plate 63 is slidably connected to the cavity wall of the air outlet pipe 5.

[0031] In this embodiment, the top of the gas storage box 4 is provided with several exhaust holes, the vertical rod of the movable rod 64 passes vertically through the exhaust holes to the outside of the gas storage box 4, and the size of the sealing plug 65 is larger than the exhaust holes.

[0032] It should be noted that the device is equipped with a main control module that works in conjunction with the exhaust gas monitoring module 33 and the gas monitoring module 41. When the monitoring data of the exhaust gas monitoring module 33 and the gas monitoring module 41 are abnormal, the main control module actively adjusts the speed of the rotary motor 31 and the length of the electric push rod 62.

[0033] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0034] The working principle of the above embodiments is as follows: (1) By starting the rotary motor 31, the rotary cylinder 32 is rotated. The outer spiral blades of the rotary cylinder 32 rotate to send the exhaust gas entering the intake box 2 to the top of the intake box 2. The exhaust gas passes outside the gearbox 34, and the exhaust gas monitoring module 33 analyzes the composition data of the exhaust gas. The rotation of the rotary motor 31 drives the transmission rod 35 to rotate, the transmission rod 35 drives the rotary rod 37 to rotate, and the rotation of the rotary rod 37 drives the guide cylinder 38 and the fan blade 381 to rotate, thus drawing the exhaust gas inside the intake box 2 from the top of the intake box 2. The exhaust gas enters the interior of the gas storage tank 4 through the vent. The exhaust gas flows through the side of the gas monitoring module 41 for composition analysis. When the data is abnormal, the electric push rod 62 pulls the sealing plate 63 down. The sealing plate 63 drives the movable rod 64 back into the interior of the gas storage tank 4, so that the sealing plug 65 blocks the exhaust port at the top of the gas storage tank 4. The downward movement of the sealing plate 63 connects the cavity of the exhaust pipe 5 with the interior of the gas storage tank 4. The exhaust gas re-enters the purification device through the exhaust pipe 5 for secondary treatment, thereby preventing the incompletely treated exhaust gas from being directly discharged into the environment and causing environmental pollution.

[0035] (2) By controlling the extension of the electric push rod 62, the movement of the electric push rod 62 pushes the sealing plate 63 to move upward to block the internal cavity of the air outlet pipe 5. At the same time, the upward movement of the sealing plate 63 drives the movable rod 64 to move the sealing plug 65 to the outside of the air storage box 4, so that the exhaust hole at the top of the air storage box 4 can be opened, and the completely treated exhaust gas smoothly enters the environment through the exhaust hole. When in use, the air inlet pipe 1 and the ship exhaust gas discharge pipe need to be connected, and the air outlet pipe 5 is connected to the exhaust gas recovery pipe. The discharge of exhaust gas is controlled according to the detection situation.
