Description

Technical Field

[0001] The utility model relates to the technical field of soot purification, in particular to a boiler soot purification device. Background Art

[0002] A boiler is an energy conversion device. The energy input into the boiler includes the chemical energy in fuel and electric energy. The boiler outputs steam, high-temperature water or organic heat carriers with a certain amount of heat energy. The original meaning of "pot" refers to a water container heated on fire, and "furnace" refers to a place where fuel is burned. A boiler includes two major parts: a pot and a furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's livelihood, or can be converted into mechanical energy through a steam power device, or further converted into electrical energy through a generator. When the boiler burns fuel to work, generally, incomplete combustion occurs, and a large amount of small particle products in the discharged soot are discharged into the air along with the flue gas, which is likely to cause pollution to the surrounding environment. It is necessary to purify the discharged soot;

[0003] The Chinese patent (Publication No.: CN215831955U) discloses a soot purification and energy-saving device for boilers, which includes a purification box. A cover plate is arranged at the top of the purification box. An air inlet pipe is fixedly connected to one side of the purification box, and an exhaust pipe is fixedly connected to the other side of the purification box. A connecting cylinder is fixedly connected to the inner wall of the purification box. A sleeve is slidably sleeved inside the connecting cylinder. A limiting plate is fixedly sleeved on the outer side of the sleeve. A tension spring is slidably sleeved on the outer side of the sleeve. A rubber plate is fixedly connected to the inner wall of the purification box. A protective pipe is arranged on one side of the rubber plate. An adsorption cylinder is fixedly sleeved inside the protective pipe. Through the design of the sleeve and the connecting cylinder, the operator aligns the two ends of the adsorption cylinder with the air inlet and the inner wall of the sleeve respectively. The tension spring pushes the sleeve to move towards the adsorption cylinder, and one end of the protective pipe contacts the side of the rubber plate, thereby realizing the installation of the adsorption cylinder, improving the convenience of the operator to install the adsorption cylinder. However, in the actual use process, when the soot is adsorbed and filtered by the adsorption cylinder, the filter material in the filter adsorption cylinder will gradually become saturated. If not replaced in time, it cannot effectively adsorb and filter the impurities and pollutants in the air. This device cannot detect the filtering effect of the adsorption cylinder, resulting in the inability to replace the adsorption cylinder in time, and when the boiler is running, the adsorption cylinder cannot be replaced, reducing the purification effect and purification efficiency. For this reason, a boiler soot purification device is proposed. Summary of the Utility Model

[0004] In view of this, the utility model provides a boiler soot purification device to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0005] The technical solution of the utility model is realized as follows: A boiler soot purification device includes a main body mechanism, a purification mechanism, and two fixing mechanisms. The purification mechanism is installed inside the main body mechanism, and the two fixing mechanisms are installed inside the main body mechanism. The main body mechanism includes a box body. An air inlet pipe is provided inside the box body. Both ends of the air inlet pipe penetrate through the box body. A U-shaped pipe is communicated with the outer side wall of the air inlet pipe. Two electromagnetic valves are symmetrically installed on both the air inlet pipe and the U-shaped pipe. A soot sensor is installed on the inner side wall of the air inlet pipe. Adsorption cylinders are provided inside both the air inlet pipe and the U-shaped pipe. Openings are provided on the outer side walls of both the air inlet pipe and the U-shaped pipe.

[0006] Further preferably, two L-shaped plates are symmetrically and fixedly connected to the inner side wall of the box body. Threaded holes are provided on the front surface of the L-shaped plates. The inner side walls of the threaded holes are threadedly connected with threaded rods. One end of each threaded rod is rotatably connected with an arc-shaped plate through a bearing. A fixing frame is fixedly connected to the inner side wall of the arc-shaped plate. A sleeve is fixedly connected to one side of the fixing frame. A plurality of through grooves are evenly provided on the outer side wall of the sleeve. The sleeve is inserted into the inside of the adsorption cylinder. The other end of the threaded rod is fixedly connected with a knob.

[0007] Further preferably, a sealing gasket is bonded to one side of the arc-shaped plate adjacent to the opening.

[0008] Further preferably, two through holes are symmetrically provided on the front surface of the L-shaped plate. Guide rods are slidably connected to the inner side walls of the two through holes. One end of each guide rod is fixedly connected with the arc-shaped plate.

[0009] Further preferably, two box doors are symmetrically hinged to the front surface of the box body. A handle is fixedly connected to the front surface of each box door.

[0010] Further preferably, a controller is installed on one side of the box body. The controller is signal-connected to the soot sensor and electrically connected to the electromagnetic valves.

[0011] Due to the adoption of the above technical solutions in the embodiments of the utility model, it has the following advantages:

[0012] First, when the utility model is in use, the filtered gas is detected by the soot sensor. When the soot sensor detects the filtered gas and the filtering effect is not ideal, it indicates that the adsorption cylinder needs to be replaced. Control the electromagnetic valves on the air inlet pipe and the U-shaped pipe to make one of the air inlet pipe and the U-shaped pipe in a flowing state and the other in a non-flowing state, so as to switch the use of the adsorption cylinders in the air inlet pipe and the U-shaped pipe, replace the adsorption cylinder in time, and improve the filtering effect.

[0013] Second, when one of the intake pipe or the U-shaped pipe is blocked, the adsorption cylinder inside the currently blocked pipe body can be replaced, which does not affect the filtration of soot, enabling the replacement of the adsorption cylinder even during the operation of the boiler and improving the filtration efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In the following text, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0024] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0025] As Figure 1-6 shown, the embodiment of the present utility model provides a boiler soot purification device, which includes a main body mechanism 1, a purification mechanism 2, and two fixing mechanisms 3. The purification mechanism 2 is installed inside the main body mechanism 1, and the two fixing mechanisms 3 are installed inside the main body mechanism 1. The main body mechanism 1 includes a box body 11. An air inlet pipe 21 is arranged inside the box body 11. Both ends of the air inlet pipe 21 penetrate through the box body 11. A U-shaped pipe 22 is communicated with the outer side wall of the air inlet pipe 21. Two electromagnetic valves 23 are symmetrically installed on both the air inlet pipe 21 and the U-shaped pipe 22. A soot sensor 24 is installed on the inner side wall of the air inlet pipe 21. Adsorption cylinders 25 are arranged inside both the air inlet pipe 21 and the U-shaped pipe 22. Openings 26 are formed on the outer side walls of both the air inlet pipe 21 and the U-shaped pipe 22.

[0026] In one embodiment, two L-shaped plates 31 are symmetrically and fixedly connected to the inner side wall of the box body 11. Thread holes 311 are formed on the front surface of the L-shaped plates 31. A threaded rod 32 is threadedly connected to the inner side wall of the thread hole 311. One end of the threaded rod 32 is rotationally connected to an arc-shaped plate 33 through a bearing. A fixing frame 36 is fixedly connected to the inner side wall of the arc-shaped plate 33. A sleeve 37 is fixedly connected to one side of the fixing frame 36. A plurality of through grooves 38 are uniformly formed on the outer side wall of the sleeve 37. The sleeve 37 is inserted into the inside of the adsorption cylinder 25. The other end of the threaded rod 32 is fixedly connected to a knob 35. Through the arrangement of the threaded rod 32, when the adsorption cylinders 25 inside the air inlet pipe 21 and the U-shaped pipe 22 need to be replaced, the knob 35 is rotated to drive the threaded rod 32 to rotate. The threaded rod 32 rotates in the thread hole 311, driving the arc-shaped plate 33 to move, so as to take out the adsorption cylinder 25 sleeved on the sleeve 37 from the air inlet pipe 21 and the U-shaped pipe 22, facilitating the replacement of the adsorption cylinder 25.

[0027] In one embodiment, a sealing gasket 39 is bonded to the side of the arc-shaped plate 33 adjacent to the opening 26. Through the arrangement of the sealing gasket 39, when the arc-shaped plate 33 seals the opening 26, the sealing gasket 39 on the arc-shaped plate 33 fits with the opening 26, improving the sealing performance between the arc-shaped plate 33 and the opening 26.

[0028] In one embodiment, two through holes 312 are symmetrically formed on the front surface of the L-shaped plate 31. The inner side walls of the two through holes 312 are slidably connected with a guide rod 34, and one end of the guide rod 34 is fixedly connected with the arc-shaped plate 33. Through the arrangement of the guide rod 34, the guide rod 34 slides in the through hole 312 to guide the moving direction of the arc-shaped plate 33.

[0029] In one embodiment, two cabinet doors 12 are symmetrically hinged to the front surface of the cabinet body 11, and a handle 13 is fixedly connected to the front surface of the cabinet door 12. Through the arrangement of the cabinet door 12, the cabinet body 11 is closed, and pulling the handle 13 facilitates the movement of the cabinet door 12.

[0030] In one embodiment, a controller 14 is installed on one side of the cabinet body 11. The controller 14 is in signal connection with the soot sensor 24, and the controller 14 is electrically connected to the solenoid valve 23. Through the arrangement of the controller 14, when the soot sensor 24 detects the filtered gas and the filtering effect is not ideal, it indicates that the adsorption cylinder 25 needs to be replaced. The controller 14 opens or closes the solenoid valve 23 on the intake pipe 21 and the U-shaped pipe 22 to control the flow of the intake pipe 21 and the U-shaped pipe 22, so as to switch the use of the adsorption cylinder 25 in the intake pipe 21 and the U-shaped pipe 22.

[0031] When the utility model is working: First, the intake pipe 21 is communicated with the boiler exhaust port. The controller 14 adjusts the opening or closing of the solenoid valve 23 on the intake pipe 21 and the U-shaped pipe 22 to keep the intake pipe 21 and the U-shaped pipe 22 in a flowing state. If the intake pipe 21 is flowing and the U-shaped pipe 22 is not flowing, the gas generated by the boiler enters the intake pipe 21 and is filtered by the adsorption cylinder 25 in the intake pipe 21. The filtered gas is detected by the soot sensor 24. When the soot sensor 24 detects the filtered gas and the filtering effect is not ideal, it indicates that the adsorption cylinder 25 needs to be replaced. At this time, the solenoid valve 23 on the intake pipe 21 is closed, and the solenoid valve 23 on the U-shaped pipe 22 is opened to make the U-shaped pipe 22 flow. The gas enters the U-shaped pipe 22 and is filtered by the adsorption cylinder 25 in the U-shaped pipe 22, and then enters the intake pipe 21 and is detected by the soot sensor 24. When it is necessary to replace the adsorption cylinder 25 inside the non-flowing intake pipe 21 or U-shaped pipe 22, the staff rotates the knob 35 to drive the threaded rod 32 to rotate. The threaded rod 32 rotates in the threaded hole 311 to drive the arc-shaped plate 33 to move, so as to take out the adsorption cylinder 25 sleeved on the sleeve 37 from the intake pipe 21 and the U-shaped pipe 22, which is convenient for replacing the adsorption cylinder 25.

[0032] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims described.
