Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, and more specifically, to a waste gas treatment device that can utilize the waste heat of boiler room exhaust gas. Background Technology

[0002] Boiler exhaust contains a lot of impurities and high heat. If the exhaust is directly released into the atmosphere, it will not only cause air pollution, but also waste heat energy.

[0003] In existing technologies, when emitting exhaust gas from a boiler room, it can be directly discharged into water, where the water absorbs impurities and heat energy from the exhaust gas. The heat energy can then be recovered through a heat exchanger. However, there are some problems in this process. When the exhaust gas is discharged into the treatment tank, it is usually in the same position, so a stirring device is needed to ensure that the water temperature in the treatment tank is uniform. Also, after the exhaust gas enters the water, it forms a large bubble that floats to the surface. Since the contact area between the bubble and the water is small, it affects the heat exchange efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem of low heat exchange efficiency after exhaust gas enters water, and to design a waste gas treatment device that can utilize the waste heat of boiler room exhaust gas.

[0005] To achieve the above objectives, the technical solution of this utility model is a waste gas treatment device that can utilize the waste heat of boiler room exhaust gas, including a treatment box containing water. An exhaust gas discharge pipe is installed on one side of the lower end of the treatment box. A heat exchanger is connected to the outside of the treatment box. A disperser is installed inside the treatment box, with an inlet pipe installed at one end. The outlet end of the exhaust gas discharge pipe is connected to the inlet pipe. The disperser can disperse the exhaust gas to various locations within the treatment box. A discharge pipe is installed on one side of the lower end of the disperser, allowing the disperser to discharge impurities in the exhaust gas through the discharge pipe.

[0006] Furthermore, the disperser includes multiple air outlet channels installed inside the processing box, with multiple air outlets at the upper end of each air outlet channel. The air inlet pipe is connected to the multiple air outlet channels via a connector. A rotating frame is installed inside each air outlet channel, and a filter screen is installed inside each air outlet. When the rotating frame rotates, it can push the impurities at the lower end of the air outlet channel to the rear. The discharge pipe is installed at the lower rear end of the air outlet channel.

[0007] Furthermore, the connector comprises multiple intake valves installed on the intake pipe, with the outlet end of each intake valve connected to the inlet end of the exhaust channel.

[0008] Furthermore, the rotating frame includes a rotating shaft located within the air outlet channel, with rolling bearings installed at both ends of the rotating shaft. The rolling bearings are installed within the air outlet channel via support rods. A spiral baffle is installed on the rotating shaft, and a rotary motor is installed at one end of the rotating shaft.

[0009] Furthermore, an impurity collection box is installed at the lower end of the processing box, the outlet end of the discharge pipe extends into the impurity collection box, and a detachable protective net is installed at the upper end of the impurity collection box.

[0010] The beneficial effects of this utility model are as follows: the exhaust gas is discharged into the disperser, which can disperse the exhaust gas to various positions in the water, so that the water does not need to be stirred by the agitator. This can make the water temperature in the treatment tank more uniform and improve the heat exchange efficiency. When the disperser disperses the exhaust gas to various positions in the treatment tank, it also reduces the volume of the bubbles, thereby increasing the contact area between the water and the bubbles and improving the heat exchange efficiency.

[0014] This utility model provides, for example Figure 1-3 The waste gas treatment device shown can utilize the waste heat of boiler room exhaust gas, including a treatment box 1 containing water. A tail gas discharge pipe 2 is installed on one side of the lower end of the treatment box 1. A heat exchanger 3 is connected to the outside of the treatment box 1. A disperser 4 is installed inside the treatment box 1. An air inlet pipe 5 is installed at one end of the disperser 4. The outlet end of the tail gas discharge pipe 2 is connected to the air inlet pipe 5. The disperser 4 can disperse the tail gas to various positions in the treatment box 1. A discharge pipe 6 is installed on one side of the lower end of the disperser 4. The disperser 4 can discharge impurities in the tail gas through the discharge pipe 6.

[0015] The process of treating the exhaust gas in this device is as follows: the exhaust gas is discharged into the disperser 4 through the exhaust gas discharge pipe 2 and the air inlet pipe 5. The disperser 4 can disperse the exhaust gas to various positions in the treatment box 1 and reduce the volume of the bubbles generated by the exhaust gas, thereby facilitating the rapid heat exchange between the exhaust gas and water. After the exhaust gas enters the water, the impurities in the exhaust gas will fall into the water and accumulate in the disperser 4, and then be discharged through the discharge pipe 6.

[0016] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 The disperser 4 includes multiple air outlet channels 7 installed in the processing box 1. Multiple air outlets 8 are opened at the upper end of the air outlet channels 7. The air inlet pipe 5 is connected to the multiple air outlet channels 7 through the connector 9. A rotating frame 10 is installed in the air outlet channel 7. A filter screen 11 is installed inside the air outlet 8. When the rotating frame 10 rotates, it can push the impurities at the lower end of the air outlet channel 7 to the rear. The discharge pipe 6 is installed at the lower rear end of the air outlet channel 7.

[0017] The process of the disperser 4 dispersing the exhaust gas is as follows: the exhaust gas can be discharged into different exhaust channels 7 through the connector 9, and then discharged through the exhaust port 8. The multiple exhaust channels 7 and multiple exhaust ports 8 make it easy to discharge the exhaust gas to different positions in the treatment box 1. The filter screen 11 at the exhaust port 8 can separate the bubbles and reduce their volume. The filter screen 11 can also intercept impurities and prevent them from mixing with the water.

[0018] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3 The connector 9 consists of multiple intake valves 12 installed on the intake pipe 5. The outlet end of the intake valve 12 is connected to the inlet end of the exhaust channel 7. By opening or closing the designated intake valve 12, the exhaust gas can enter the designated exhaust channel 7.

[0019] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The rotating frame 10 includes a rotating shaft 13 located in the air outlet channel 7. Rolling bearings 14 are installed at both ends of the rotating shaft 13. The rolling bearings 14 are installed in the air outlet channel 7 through support rods 15. A spiral baffle 16 is installed on the rotating shaft 13. A rotary motor 17 is installed at one end of the rotating shaft 13.

[0020] The process of conveying impurities by the rotating frame 10 is as follows: Impurities entering the air outlet channel 7 can accumulate at its lower end. The rotating motor 17 is started to rotate, which can drive the rotating shaft 13 and the spiral baffle 16 to rotate. Under the action of the spiral baffle 16, the impurities can move to the rear. When the impurities move to the top of the discharge pipe 6, they can move downward under the action of gravity. When the spiral baffle 16 rotates, it can also divide and push the airflow in the air outlet pipe 7, making it easier for the airflow to move to the rear.

[0021] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 An impurity collection box 18 is installed at the lower end of the processing box 1. The outlet end of the discharge pipe 6 extends into the impurity collection box 18. A detachable protective net 19 is installed at the upper end of the impurity collection box 18. Impurities discharged from the discharge pipe 6 can fall into the impurity collection box 18. The protective net 19 can prevent impurities from leaking out, thus facilitating the collection of impurities. After a period of use, the protective net 19 can be removed and the impurity collection box 18 can be cleaned.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
