Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, in particular to a garbage incineration hydrogen chloride monitoring pretreatment device. Background Art

[0002] Waste incineration plays an important role in environmental management and resource utilization. Waste incineration can convert organic matter in waste into energy, such as electricity or heat energy, thereby realizing resource recycling and reducing dependence on traditional energy. Waste incineration can greatly reduce the volume of waste, thereby reducing the demand for landfills, extending the service life of landfills, and reducing the waste of land resources. Waste incineration not only generates a large amount of heat energy, but also generates smoke, toxic gases, smoke, etc. Among them, hydrogen chloride can cause great harm to the human respiratory tract. Therefore, it is necessary to install hydrogen chloride monitoring equipment in the flue, and configure corresponding hydrogen chloride adsorption measures by detecting the concentration of hydrogen chloride. At present, the probe part of the hydrogen chloride monitoring device is placed inside the flue for detection. In order to avoid partial blockage of the probe, a filter structure is generally designed on the outside of the probe, but the filter structure will become blocked after a long working time, and the general blowing and washing method cannot clean it. It is necessary to shut down and dismantle the filter structure for replacement. The shutdown and replacement of the filter structure affects the continuous operation of the system, and the equipment loss is large, which is urgently needed. Therefore, we propose a waste incineration hydrogen chloride monitoring pretreatment equipment. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Embodiment 1, as Figure 1-4 As shown, the utility model provides a technical solution: a garbage incineration hydrogen chloride monitoring pretreatment device, comprising a detection shell 1 installed inside the incineration flue 14, the left and right ends of the detection shell 1 are respectively provided with an air inlet and an air outlet, the air inlet and the air outlet are both provided with a filter 3, a platform seat 2 is fixedly provided on the top of the detection shell 1, the top surface of the platform seat 2 is connected to the top seat 8 through a bracket 5, a driving motor 13 is fixedly provided on the top surface of the top seat 8, a gear 11 is coaxially provided on the motor shaft of the driving motor 13, and the inside of the detection shell 1 is along the incineration flue A filter element mechanism 1 6 and a filter element mechanism 2 7 are movably arranged in the wind direction 14. A tooth row 10 and a tooth row 2 12 are arranged at one end of the filter element mechanism 1 6 and the filter element mechanism 2 7 close to the gear 11. The tooth row 10 and the tooth row 2 12 are meshed with the gear 11. A hydrogen chloride monitor 4 is arranged on the top surface of the platform seat 2. The probe of the hydrogen chloride monitor 4 is located inside the detection shell 1. The filter element mechanism 1 6, the filter element mechanism 2 7 and the probe of the hydrogen chloride monitor 4 are arranged along the wind direction of the incineration flue 14. The filter element mechanism 2 7 and the filter element mechanism 1 6 are arranged alternately up and down.

[0020] In a specific embodiment of the utility model, the top of the incineration flue 14 is opened for installing the detection housing 1, and the platform seat 2 is fixed to the top surface of the incineration flue 14 by bolts. A cavity matching the outer dimensions of the filter element mechanism 1 6 and the filter element mechanism 2 7 is formed inside the detection housing 1, and the two cavities are separated by a partition 101. The partition 101 is provided with a ventilation hole to establish a communication relationship. The filter element mechanism 1 6 and the filter element mechanism 2 7 are both provided with a sealing ring 17, which is used to closely fit with the through hole 15 and the through hole 2 16 respectively to improve the sealing performance. 02 is used to improve the stability of the filter element mechanism 1 6 and the filter element mechanism 2 7 when they are installed inside the detection housing 1. The split filter element 18 of the filter element mechanism adopts nanofibers. The nanofibers have a high surface area and a small pore size, which can effectively capture larger particles and have a small adsorption of gas molecules such as hydrogen chloride. The hydrogen chloride monitor 4 includes a processing host and a hydrogen chloride detection sensor. The hydrogen chloride detection sensor adopts an electrochemical hydrogen chloride sensor, which reacts with specific chemical substances to generate current changes, and determines the concentration of hydrogen chloride by measuring the current changes.

[0021] In the preferred technical solution, the top surface of the detection shell 1 is provided with a through hole 15 for accommodating the up and down movement of the filter element mechanism 1 6, and the top surface of the detection shell 1 is provided with a through hole 16 for accommodating the up and down movement of the filter element mechanism 2 7. The top and bottom of the filter element mechanism 1 6 and the filter element mechanism 2 7 are both inlaid with sealing rings 17. The provision of the sealing ring can improve the sealing performance of the filter element mechanism when it cooperates with the through hole.

[0022] In the preferred technical solution, two recessed holes 102 of the same size are opened at the bottom of the inner wall of the detection shell 1, and the two recessed holes 102 are vertically aligned with the through hole 15 and the through hole 2 16 respectively. The recessed holes 102 are used to improve the stability of the filter element mechanism 1 6 and the filter element mechanism 2 7 when they are installed inside the detection shell 1.

[0023] In the preferred technical solution, limiting rods 9 are fixedly provided on the top surfaces of filter element mechanism 1 6 and filter element mechanism 2 7. The limiting rods 9 of filter element mechanism 1 6 and filter element mechanism 2 7 are both connected through the top seat 8. The limiting rods 9 limit the filter element mechanism to only move in the vertical position, thereby improving the stability of the filter element mechanism in moving up and down.

[0024] In the preferred technical solution, a partition 101 for separating the filter element mechanism 1 6 and the filter element mechanism 2 7 is fixedly provided inside the detection shell 1, and an air flow channel hole is opened in the middle of the partition 101. The partition 101 is used to separate the two cavities accommodating the filter element mechanism 1 6 and the filter element mechanism 2 7, so that the air flow must pass through the air flow channel hole in the middle of the partition 101 when passing through.

[0025] In the preferred technical solution, both the filter element mechanism 1 6 and the filter element mechanism 2 7 are composed of a cylinder and a split filter element 18. The split filter element 18 is detachably connected to the cylinder by bolts, so that the split filter element 18 can be easily disassembled for replacement and maintenance.

[0026] Working principle: in the initial state, the filter element mechanism 1 6 is located inside the detection housing 1, the sealing ring on the top of the filter element mechanism 1 6 blocks the through hole 15, and the sealing ring on the bottom of the filter element mechanism 2 7 blocks the through hole 2 16, and the drive motor 13 does not work. At this time, the smoke from the incineration flue 14 passes through the filter screen 3 at the air inlet to filter large particles of foreign matter, and then is filtered through the filter element mechanism 1 6. The gas then contacts the probe of the hydrogen chloride monitor 4 through the partition 101, so as to perform smoke detection. After a period of time, the drive motor 13 is controlled to drive the gear 11 to rotate clockwise, so that according to the meshing movement principle of the gear and the tooth row, and because The limiting rod 9 limits the filter element mechanism to move only in the vertical position, so that the filter element mechanism 1 6 moves up and the filter element mechanism 2 7 moves down, until the sealing ring at the bottom of the filter element mechanism 1 6 blocks the through hole 15 and the sealing ring at the top of the filter element mechanism 2 7 blocks the through hole 2 16. At this time, the smoke is filtered by the filter element mechanism 2 7, and the gas then contacts the probe of the hydrogen chloride monitor 4 through the partition 101, so as to perform smoke detection. By removing the bolts used to fasten the split filter element 18 of the filter element mechanism 1 6, the split filter element 18 can be removed and replaced. At this time, the incineration flue 14 can still transport smoke normally, and will not affect the continuity of the operation of the garbage incineration system.
