Description

Technical Field

[0001] This utility model relates to the field of denitrification catalysis technology, and in particular to a low-temperature denitrification device for glass products. Background Technology

[0002] With the increasing emphasis placed on environmental protection by the government, a series of stringent environmental regulations have been introduced. These regulations impose higher requirements on industrial emissions, particularly regarding the emission of pollutants such as nitrogen oxides (NOx). The fumes generated during the glass manufacturing process contain high concentrations of NOx; therefore, in order to meet environmental regulations, denitrification treatment must be performed on glass products.

[0003] Publication No. CN211886169U discloses a low-temperature denitrification device, including a reactor. A burner is fixedly connected to the lower outer surface of the reactor, and a flue gas inlet pipe is fixedly connected to the outer wall of the burner. A feeding port is provided on the outer wall of the reactor, and a flow pipe is provided at the upper end of the reactor. A detachable filter-type bellows mechanism is provided at one end of the flow pipe, and a vent pipe is provided at the other end of the detachable filter-type bellows mechanism. This low-temperature denitrification device, with its detachable filter-type bellows mechanism and gas detection and control module, facilitates better fan filtration operation, increases the purification effect of flue gas, and provides excellent filtration performance. It is easy to use and allows for convenient detection of flue gas concentration at the outlet, facilitating observation of the flue gas purification effect and preventing device malfunctions that could result in polluted flue gas output, thus offering better application prospects.

[0004] The mixing effect between the reducing agent and the flue gas affects the subsequent reaction results. However, the above-mentioned device does not take into account the mixing effect between the reducing agent and the flue gas, which can easily affect the subsequent reaction results. Therefore, there is a need to propose a low-temperature denitrification device for glass products. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as poor mixing of reducing agent and flue gas, which can easily affect subsequent reaction effects, by proposing a low-temperature denitrification device for glass products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A low-temperature denitrification device for glass products includes a dust removal mechanism, a disturbance mechanism, and a reaction mechanism, which are sequentially connected to each other. The disturbance mechanism includes a disturbance cylinder, and a disturbance body is movably disposed inside the disturbance cylinder. The cross-sectional diameter of the disturbance body gradually increases uniformly from both ends toward the center. Several disturbance protrusions are fixedly installed at equal intervals on the outer wall of the disturbance body. An installation rod is fixedly installed on the inner wall of the disturbance cylinder. One end of the disturbance body is rotatably connected to the top of the installation rod, and a movable component is disposed at the end of the disturbance body away from the installation rod.

[0008] Used to mix the gas entering the turbulence cylinder, ensuring that ammonia and flue gas are fully mixed to facilitate subsequent reaction processing. When ammonia and flue gas enter the turbulence cylinder, the gas impacts the turbulence body, causing the turbulence body to be disturbed around the top of the mounting rod under the action of the moving components. The disturbance protrusions on the surface of the turbulence body ensure that ammonia and flue gas are fully mixed.

[0009] Preferably, the active component includes a fixed mounting block fixedly installed on the inner side wall of the disturbance cylinder, a fixed sliding rod fixedly installed between the fixed mounting blocks, a sliding sleeve block slidably sleeved on the fixed sliding rod, and a pair of functional springs sleeved on the fixed sliding rod. The pair of functional springs are symmetrically arranged at the top and bottom of the sliding sleeve block, and the functional springs are elastically connected between the inner side wall of the fixed mounting block and the outer side wall of the sliding sleeve block.

[0010] This device is used to cause the disturbance to move under the impact of gas. When ammonia and flue gas impact the disturbance, the disturbance moves. The sliding block moves on the fixed slide rod, causing the functional spring to stretch or compress. Under the reaction force of the functional spring, the sliding block drives the disturbance to reciprocate.

[0011] Preferably, the dust removal mechanism includes a separation cylinder, an air inlet pipe is connected to the top of the outer side wall of the separation cylinder, an air delivery pipe is connected to the top of the separation cylinder, and a discharge pipe is opened at the bottom of the separation cylinder;

[0012] The separator is inverted conical in shape, with the inner wall of the air inlet pipe tangent to the top of the inner wall of the separator, and the other end of the air delivery pipe connected to the disturbance cylinder.

[0013] Used for dust removal of flue gas, the flue gas enters the separator cylinder through the inlet pipe, forming a strong rotating airflow inside the separator cylinder. During this process, due to their large mass, the solid particles are subjected to centrifugal force much greater than their gravity and inertial force, and are thus pushed against the inner wall of the separator cylinder. They move along the wall with the rotating airflow and are finally discharged from the discharge pipe at the bottom of the separator cylinder. At the same time, the purified gas forms an upward internal vortex in the central area and is transported to the turbulence cylinder through the gas delivery pipe at the top.

[0014] Preferably, the disturbance cylinder is connected to an ammonia inlet pipe at one end near the gas delivery pipe, and to several connecting pipes at the other end of the disturbance cylinder;

[0015] Preferably, the reaction mechanism includes a reaction chamber, in which several low-temperature reaction mesh plates are fixedly installed, and the other end of a connecting pipe extends into the reaction chamber. The connecting pipe is located below the several low-temperature reaction mesh plates, and an exhaust pipe is connected to the top of the reaction chamber.

[0016] Used to react a mixture of flue gas and ammonia.

[0017] This utility model has the following beneficial effects:

[0018] 1. By setting up a disturbance mechanism, when ammonia and flue gas enter the disturbance cylinder, the gas impacts the disturbance body, causing the disturbance body to be disturbed around the top of the mounting rod under the action of the moving component. Combined with the disturbance protrusions on the surface of the disturbance body, the ammonia and flue gas are fully mixed, which facilitates subsequent reaction processing.

[0019] 2. By setting up movable components, when ammonia and flue gas impact the disturbance body, the disturbance body is made to move. The sliding sleeve moves on the fixed slide rod, causing the functional spring to stretch or compress. Under the reaction force of the functional spring, the sliding sleeve drives the disturbance body to reciprocate. Attached Figure Description

[0028] Reference Figure 1-5 A low-temperature denitrification device for glass products includes a dust removal mechanism 1, a disturbance mechanism 2, and a reaction mechanism 3. The dust removal mechanism 1, the disturbance mechanism 2, and the reaction mechanism 3 are sequentially connected to each other. The disturbance mechanism 2 includes a disturbance cylinder 21. A disturbance body 22 is movably disposed inside the disturbance cylinder 21. The cross-sectional diameter of the disturbance body 22 gradually and uniformly increases from both ends toward the center. Several disturbance protrusions 23 are fixedly and uniformly installed at equal intervals on the outer wall of the disturbance body 22. An installation rod 24 is fixedly installed on the inner wall of the disturbance cylinder 21. One end of the disturbance body 22 is rotatably connected to the top end of the installation rod 24. A movable component 25 is disposed at the end of the disturbance body 22 away from the installation rod 24.

[0029] The active component 25 includes a fixed mounting block 251 fixedly installed on the inner side wall of the disturbance cylinder 21. A fixed sliding rod 252 is fixedly installed between the fixed mounting blocks 251. A sliding sleeve block 253 is slidably sleeved on the fixed sliding rod 252. A pair of functional springs 254 are sleeved on the fixed sliding rod 252. The pair of functional springs 254 are symmetrically arranged at the top and bottom of the sliding sleeve block 253. The functional springs 254 are elastically connected between the inner side wall of the fixed mounting block 251 and the outer side wall of the sliding sleeve block 253.

[0030] The dust removal mechanism 1 includes a separation cylinder 11, an air inlet pipe 12 connected to the top of the outer wall of the separation cylinder 11, an air delivery pipe 13 connected to the top of the separation cylinder 11, and a discharge pipe 14 opened at the bottom of the separation cylinder 11.

[0031] The separator 11 is inverted cone shape, the inner wall of the air inlet pipe 12 is tangent to the top of the inner wall of the separator 11, and the other end of the air delivery pipe 13 is connected to the disturbance cylinder 21.

[0032] The disturbance cylinder 21 is connected to an ammonia inlet pipe 4 at one end near the gas transmission pipe 13, and to several connecting pipes 5 at the other end of the disturbance cylinder 21.

[0033] The reaction mechanism 3 includes a reaction chamber 31, in which several low-temperature reaction mesh plates 32 are fixedly installed. The other end of the connecting pipe 5 extends into the reaction chamber 31. The connecting pipe 5 is located below the several low-temperature reaction mesh plates 32. The top of the reaction chamber 31 is connected to an exhaust pipe 33.

[0034] In this invention, flue gas enters the separator 11 through the inlet pipe 12, forming a strong rotating airflow inside the separator 11. During this process, solid particles, due to their large mass, experience a centrifugal force much greater than their gravitational and inertial forces, and are thus pushed against the inner wall of the separator 11. They then move along the wall with the rotating airflow and are finally discharged from the outlet pipe 14 at the bottom of the separator 11. Simultaneously, the purified gas forms an upward internal vortex in the central region and is transported to the turbulence cylinder 21 through the top gas delivery pipe 13. Ammonia gas enters through the ammonia gas inlet pipe 4. When the ammonia and flue gas impact the disturbance body 22 inside the disturbance cylinder 21, the disturbance body 22 moves, and the sliding sleeve 253 moves on the fixed slide rod 252, causing the functional spring 254 to stretch or compress. Under the reaction force of the functional spring 254, the sliding sleeve 253 drives the disturbance body 22 to reciprocate. With the help of the disturbance protrusions 23 on the surface of the disturbance body 22, the ammonia and flue gas are fully mixed, which facilitates the subsequent reaction processing. The mixed gas enters the reaction chamber 31 through the connecting pipe 5, and the low-temperature reaction mesh plate 32 performs reaction processing on the mixed gas.
