Description

Technical Field

[0001] This utility model belongs to the field of industrial waste gas treatment and detection technology, specifically relating to an anti-water vapor interference mechanism for a furnace and kiln waste gas sulfur dioxide and ammonia analysis equipment. Background Technology

[0002] Industrial furnace and kiln exhaust gas refers to the collective term for gases containing various pollutants generated during the combustion of fuel in industrial furnaces and kilns. The main pollutants in furnace and kiln exhaust gas include sulfur dioxide, nitrogen oxides, carbon monoxide, ammonia, and particulate matter. If these pollutants are directly released into the atmosphere, they will severely pollute the air quality and subsequently harm human health through the respiratory system. To treat pollutants in furnace and kiln exhaust gas, enterprises generally adopt mature technologies such as wet desulfurization, SCR denitrification, and baghouse dust collection.

[0003] Currently, to verify the effectiveness of pollution control and monitor in real time whether the concentration of sulfur dioxide or other waste gas components in furnace and kiln exhaust gas exceeds the standard, an online exhaust gas analysis device is often installed at the furnace and kiln exhaust gas outlet. Enterprises can dynamically adjust their production conditions based on changes in pollutant concentration data from this online analysis device to ensure stable and compliant emissions. However, the online analysis device originally used to detect sulfur dioxide in furnace and kiln exhaust gas has the following shortcomings in actual use: Because the furnace and kiln exhaust gas contains some water vapor, the water vapor directly enters the exhaust gas analysis device, easily causing condensation inside the device. This affects the normal flow of the gas path and the normal analysis function, resulting in significant data errors. To control the impact of water vapor on the analysis data, enterprise staff need to regularly inspect and manually drain the gas path of the exhaust gas analysis device, increasing the workload and difficulty of its actual use.

[0004] Therefore, a new type of anti-water vapor interference mechanism is needed for the analysis equipment of sulfur dioxide and ammonia in furnace exhaust gas. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing furnace exhaust gas analysis equipment is easily affected by residual water vapor in the exhaust gas, thus interfering with the normal operation of the equipment. To achieve the above objective, this invention discloses an anti-water vapor interference mechanism for furnace exhaust gas sulfur dioxide and ammonia analysis equipment. The technical solution of this invention is as follows:

[0006] An anti-moisture interference mechanism for a furnace exhaust gas sulfur dioxide and ammonia analysis device includes a treatment box, with connecting gas pipes extending from both ends of the treatment box. Two symmetrical guide blocks extend from both ends of the inner cavity of the treatment box, with the ends of the guide blocks tilting downwards. An inverted triangular condensing metal block is embedded in the top opening of the treatment box. A box cover is installed at the side opening of the treatment box. A movable cover plate extending into the inner cavity of the treatment box is horizontally inserted into the box cover. Both ends of the movable cover plate extend into a strainer box positioned between the condensing metal block and the guide blocks. Each strainer box contains absorbent silica gel particles. A liquid collection box corresponding to the notch between the two guide blocks extends from the bottom of the movable cover plate.

[0007] As a preferred embodiment of this utility model, the two connecting air pipes are coaxial, and each connecting air pipe is provided with an external thread.

[0008] As a preferred embodiment of this utility model, the movable cover plate is rotatably mounted with an external stud, and the external stud is adapted to the internal thread hole of the cover.

[0009] As a preferred embodiment of this utility model, the external stud extends coaxially to form a quick-release knob located outside the processing box.

[0010] As a preferred embodiment of this utility model, the upper end of the condensed metal block extends with several equidistantly distributed heat dissipation fins.

[0011] As a preferred technical solution of this utility model, the absorbent silicone particles of each of the mesh boxes are wrapped with a pure cotton mesh bag.

[0012] As a preferred embodiment of this utility model, each of the mesh boxes is provided with a through hole that accommodates the airflow between the two connecting air pipes.

[0013] As a preferred embodiment of this utility model, both ends of the processing box extend into L-shaped mounting ribs, and the mounting ribs are provided with mounting holes for fixing to external objects.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, an anti-moisture interference mechanism is first connected in series with the commonly used furnace exhaust gas analysis equipment. Exhaust gas containing moisture can enter the treatment box through the connecting gas pipe. When some of the moisture comes into contact with the condensing metal blocks arranged in an inverted triangle, it can be converted from vaporization to liquefaction. Then, it flows into the collection box by gravity along the guide inclined block. The other part of the moisture can flow in the gas cavity formed by the condensing metal block and the guide inclined block, and then enter the strainer box. When the pure cotton mesh bag and water-absorbing silica gel particles in the strainer box come into contact with the moisture, they can absorb the moisture. Only after comprehensive dehydration will the exhaust gas continue to enter the exhaust gas analysis equipment. This structure can perform comprehensive dehydration treatment on the exhaust gas entering the exhaust gas analysis pipeline before analysis, which can effectively reduce the interference of moisture entering the exhaust gas analysis equipment with subsequent exhaust gas analysis operations, thereby improving the stability and maintenance convenience of the exhaust gas analysis equipment.

Detailed Implementation

[0021] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0022] Please see Figure 1-3 An anti-moisture interference mechanism for a furnace exhaust gas sulfur dioxide and ammonia analysis device includes a treatment box 1, with connecting gas pipes 101 extending from both ends of the treatment box 1. The two connecting gas pipes 101 are coaxial, and each connecting gas pipe 101 is provided with external threads. Two symmetrical guide ramps 102 extend from both ends of the inner cavity of the treatment box 1, with the ends of the two guide ramps 102 inclined downwards. An inverted triangular condensation metal block 3 is embedded in the top opening of the treatment box 1.

[0023] A cover 2 is installed at the side opening of the treatment box 1, and a movable cover plate 4 extending into the inner cavity of the treatment box 1 is inserted laterally into the cover 2. Both ends of the top of the movable cover plate 4 extend into a strainer box 401 positioned between the condensing metal block 3 and the guide ramp 102. Each strainer box 401 contains absorbent silica gel particles 7. The top and bottom of the strainer box 401 are respectively attached to the condensing metal block 3 and the guide ramp 102, and the side wall of the strainer box 401 away from the movable cover plate 4 is attached to the inner wall of the treatment box 1. A collection box 402 corresponding to the notch between the two guide ramps 102 extends from the bottom of the movable cover plate 4. Each strainer box 401 has a through hole to accommodate the airflow between the two connecting air pipes 101.

[0024] The cover 2 has through holes for the strainer box 401 and the collection box 402 to pass through. An external stud 5 is rotatably mounted on the movable cover 4, and the external stud 5 is fitted with an internal threaded hole 201 in the cover 2. A quick-release knob 501 extends coaxially from the external stud 5 and is located on the outside of the treatment box 1. This facilitates the operator's grip and adjustment of the external stud 5. When the external stud 5 is screwed into the internal threaded hole 201, the movable cover 4 can be stably locked and fixed onto the cover 2.

[0025] Each filter box 401 has its absorbent silica gel particles 7 wrapped in a pure cotton mesh bag 6. Both the pure cotton mesh bag 6 and the absorbent silica gel particles 7 have excellent water absorption effects, which can comprehensively absorb and treat the water vapor in the exhaust gas, thereby reducing the water vapor content in the exhaust gas.

[0026] The condensing metal block 3 is shaped like an isosceles triangle with its apex pointing downwards. This allows liquefied water vapor to flow towards the center and then drip into the collection box 402 by gravity. Several equidistant heat dissipation fins 301 extend from the upper end of the condensing metal block 3, effectively increasing the contact area at the top and thus improving its heat dissipation and condensation efficiency. The condensing metal block 3 can be made of metals such as copper or aluminum.

[0027] Both ends of the treatment box 1 extend L-shaped mounting ribs 8, and the mounting ribs 8 are provided with mounting holes 801 for fixing to external objects. The different positions of the mounting ribs 8 and the mounting holes 801 make it easy for the treatment box 1 to be fixed to the fixed position of the exhaust gas analysis equipment by side mounting or bottom mounting with fasteners.

[0028] Working principle:

[0029] In use, the anti-water vapor interference mechanism is installed into the exhaust gas analysis equipment using fasteners and mounting ribs 8. Then, the air inlet pipe of the exhaust gas analysis equipment is connected to one of the connecting air pipes 101 on the treatment box 1 through a rubber hose. The other connecting air pipe 101 on the treatment box 1 is then connected to the exhaust gas discharge pipe. This completes the installation of the anti-water vapor interference mechanism. Before daily use, the operator can insert unused water-absorbing bags (composed of water-absorbing silica gel particles 7 and pure cotton mesh bags 6) into the two strainer boxes 401 respectively. Then, the accumulated water in the liquid collection box 402 is poured out. The movable cover plate 4 can then be slid horizontally onto the box cover 2. Then, the operator can hold and turn the quick-release knob 501 to screw the external stud 5 into the internal thread hole 201 of the box cover 2. At this time, the movable cover plate 4 can stably cover the box cover 2, and the two strainer boxes 401 and the liquid collection box 402 can then enter the treatment box 1.

[0030] In actual use, the exhaust gas in the exhaust pipe can enter the treatment box 1. The exhaust gas can flow between the condensing metal block 3 and the guide inclined block 102 in the treatment box 1. When some water vapor enters the treatment box 1, it can come into contact with the condensing metal block 3 which is distributed in an inverted triangle. The vaporized water vapor can be converted into liquefaction by pre-cooling. Then, it flows into the collection box 402 by gravity on the inclined surface of the guide inclined block 102 or the apex of the condensing metal block 3. When another part of the water vapor enters the treatment box 1, it can enter and pass through the strainer box 401. The pure cotton mesh bag 6 and water-absorbing silica gel particles 7 in the strainer box 401 can absorb the water vapor. The exhaust gas after comprehensive dehydration can enter the exhaust gas analysis equipment through the connecting air pipe 101 and the air inlet pipe for subsequent analysis and treatment.

[0031] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
