Description
Technical Field
[0001] This utility model relates to the field of anti-clogging ash honeycomb denitrification catalyst technology, specifically to a production device for an anti-clogging ash honeycomb denitrification catalyst. Background Technology
[0002] With increasingly stringent national air pollution prevention and control policies, pollutant emission standards for coal-fired power plants and industrial furnaces are constantly being raised, and ultra-low emission standards are gradually being implemented. Due to its high denitrification efficiency and stable operation, SCR denitrification technology has become the mainstream technology for flue gas denitrification. In the entire SCR denitrification process, the denitrification catalyst is a key component, which is directly related to the stable operation of the denitrification system and the compliance of flue gas emissions with standards.
[0003] For example, the authorization announcement number "CN214973059U" is titled "Anti-clogging ash honeycomb denitrification catalyst unit." Compared with ordinary honeycomb denitrification catalysts, it increases the flue gas flow area and intercept within the same horizontal cross-section, increasing the difficulty of ash bridging in the flue gas and thus reducing the probability of clogging. Existing anti-clogging ash honeycomb denitrification catalyst units require a series of thorough processing and production before they can be put into formal use. For example, titanium dioxide, active ingredient powder, and auxiliary materials such as glass fiber, deionized water, ammonia, extrusion aid, and binder should be added in sequence and stirred at high speed to form a plastic material that is easy to extrude. Then, it is filtered and shaped, and finally dried and calcined to produce a qualified catalyst. However, when drying the shaped honeycomb denitrification catalyst, the temperature needs to be precisely controlled. The heat source used for drying should not be directly close to the honeycomb denitrification catalyst, because direct high-temperature baking will destroy the structural stability of the honeycomb denitrification catalyst. Therefore, the honeycomb denitrification catalyst will produce more pores and cracks, which will reduce the production quality of the anti-clogging ash honeycomb denitrification catalyst unit.

[0012] The present invention proposes a production device for an anti-clogging ash-filled honeycomb denitrification catalyst, which has the following advantages: the horizontal plate can be raised and lowered after the electric push rod is connected to the power supply. This raising and lowering of the horizontal plate can adjust the height of the frame composed of the partition and support rod, and thus adjust the height of the frame composed of the partition and support rod from the heating tubes on both sides. The closing door can be manually rotated outward to open. After opening and closing the door, the formed anti-clogging ash-filled honeycomb denitrification catalyst can be placed on the partition for drying. The further the electric push rod drives the partition from the heating tube, the more easily it will crack and develop holes due to direct heat source baking, which can be alleviated, thus improving the production quality of the anti-clogging ash-filled honeycomb denitrification catalyst production device.

[0023] The heating and drying ventilation structure 4 includes an air inlet 41 and a connecting plate 44. The two connecting plates 44 are fixedly installed on both sides of the inner wall of the drying chamber 3. The connecting plates 44 are used to support the two vertical partition plates 45 fixed on both sides of the drying chamber 3. The two vertical partition plates 45 can separate the heating tube 43 and the anti-clogging ash honeycomb denitrification catalyst waiting to be dried, so that the anti-clogging ash honeycomb denitrification catalyst stored in this way is not easily in direct contact with the heat source.
[0024] Two connecting plates 44 are fixedly connected to the lower ends of partition plates 45. Two air inlets 41 are fixedly opened on both sides of the outer wall of the drying chamber 3. The air inlets 41 are used to send external air into the drying chamber 3. Support blocks 42 are fixedly connected to the lower ends of the inner wall of the drying chamber 3. The support blocks 42 fix the vertical heating tube 43 inside the air inlet 41. When the power is connected and the heating tube 43 is started, the external air will be heated by the heat generated by the heating tube 43. The heating tube 43 is fixedly connected to the inner side of the two support blocks 42.
[0025] The heating adjustment structure 5 includes electric push rods 51 and a horizontal plate 53. Two electric push rods 51 are fixedly connected to the bottom of the inside of the drying oven 3. The top of the electric push rods 51 supports the sliders 52. The top of the two electric push rods 51 is fixedly connected to the sliders 52. The horizontal plate 53 is fixedly connected above the two sliders 52. The horizontal plate 53 can support the frame composed of the top partition 55 and the support rod 54. The horizontal plate 53 can be raised and lowered after the electric push rods 51 are connected to the power supply.
[0026] The horizontal plate 53, which can be raised and lowered in this way, can adjust the height of the frame composed of the partition plate 55 and the support rod 54, and thus adjust the height of the frame composed of the partition plate 55 and the support rod 54 from the heating tubes 43 on both sides. The partition plate 55 is fixedly installed on the top of the horizontal plate 53, and the support rod 54 is fixedly connected between multiple partition plates 55. The outer wall of the drying chamber 3 is hinged to a closing door 56. The closing door 56 can be manually rotated outward to open. After the closing door 56 is opened, the molded anti-clogging honeycomb denitrification catalyst can be placed on the partition plate 55 for drying.
[0027] The top of the electric push rod 51 supports the slider 52. The horizontal plate 53 supports the frame composed of the top partition 55 and the support rod 54. The horizontal plate 53 can be raised and lowered after the electric push rod 51 is connected to the power supply. The raised and lowered horizontal plate 53 can adjust the height of the frame composed of the partition 55 and the support rod 54, and thus adjust the height of the frame composed of the partition 55 and the support rod 54 from the heating tubes 43 on both sides. The closing door 56 can be manually rotated outward to open. After opening and closing the closing door 56, the molded anti-clogging ash honeycomb denitrification catalyst can be placed on the partition 55 for drying. When the electric push rod 51 drives the partition 55 further away from the heating tube 43, the problem of cracking and pores caused by direct heat source baking can be alleviated, thus improving the production quality of the anti-clogging ash honeycomb denitrification catalyst production device.
[0028] The moisture emission structure 6 includes a motor 61 and an exhaust plate 63. The motor 61 is fixedly connected to the lower end of the drying chamber 3. The motor 61 is a servo motor. When selecting a servo motor, you can choose a motor model that meets the usage requirements. The lower half of the motor 61 is set inside the fixed base 1. The rear end of the fixed base 1 is provided with a ventilation structure for heat dissipation of the motor 61. The upper output shaft of the motor 61 is fixedly connected to a drive fan 62. The exhaust plate 63 is fixedly installed on the top of the drying chamber 3.
[0029] When the power supply is connected and the motor 61 is started, the motor 61 will drive the upper drive fan 62 to rotate. The drive fan 62 can drive the air upward. Then, the air carrying hot air passes through the multi-layer partition 55 on which the anti-clogging ash honeycomb denitrification catalyst is placed, and the anti-clogging ash honeycomb denitrification catalyst is dried. The moisture will be discharged upward along the exhaust holes 64 drilled on the exhaust plate 63. Multiple exhaust holes 64 are fixedly opened on the inner side of the exhaust plate 63.
[0030] A temperature sensor 7 is fixedly installed at the top of the inside of the drying oven 3. The temperature sensor 7 is made of a thermistor semiconductor. It converts the physical properties caused by temperature changes into measurable electrical signals or other forms of information and outputs them to the temperature display screen 2. This allows the staff to view the temperature readings on the temperature display screen 2 to coordinate with the drying process. The temperature sensor 7 is electrically connected to the temperature display screen 2 below through wires.
[0031] Working principle:
[0032] The production unit for anti-clogging ash honeycomb denitrification catalyst is used to produce and process anti-clogging ash honeycomb denitrification catalyst. In the specific processing, it is necessary to first mix the titanium dioxide, active ingredient powder and auxiliary materials such as glass fiber, deionized water, ammonia water, extrusion aid and binder in sequence, and mix them at high speed to form a plastic material that is easy to extrude. The automatic feeding system controlled by the program ensures the accurate quantitative measurement of raw materials and guarantees the uniformity of the final product. Then, the material is filtered and shaped. The pre-filtered extruder is equipped with a filter screen to filter out impurities and pre-shape the material. The filtered raw material is fed into the twin-screw vacuum extruder for product extrusion and shaping. This facilitates the subsequent drying and calcination processing and shaping. Finally, the calcined finished product needs to be cut neatly by a cutting machine.
[0033] Air heating structure of the production unit for anti-clogging honeycomb denitrification catalyst:
[0034] The connecting plate 44 is used to support the two vertical partition plates 45 fixed on both sides of the drying box 3. The two vertical partition plates 45 can separate the heating tube 43 and the anti-clogging ash honeycomb denitrification catalyst waiting to be dried. In this way, the anti-clogging ash honeycomb denitrification catalyst is not easily in direct contact with the heat source. The air inlet 41 is used to send external air into the drying box 3. The support block 42 fixes the vertical heating tube 43 inside the air inlet 41. When the power is connected and the heating tube 43 is started, the external air will be heated by the heat generated by the heating tube 43.
[0035] Adjustable heating and drying structure of the production unit for anti-clogging honeycomb denitrification catalyst:
[0036] The top of the electric push rod 51 supports the slider 52. The horizontal plate 53 supports the frame composed of the top partition 55 and the support rod 54. The horizontal plate 53 can be raised and lowered after the electric push rod 51 is connected to the power supply. The raised and lowered horizontal plate 53 can adjust the height of the frame composed of the partition 55 and the support rod 54, and thus adjust the height of the frame composed of the partition 55 and the support rod 54 from the heating tubes 43 on both sides. The closing door 56 can be manually rotated outward to open. After opening and closing the closing door 56, the molded anti-clogging honeycomb denitrification catalyst can be placed on the partition 55 for drying. When the electric push rod 51 drives the partition 55 further away from the heating tube 43, the problem of cracking and pores caused by direct heat source baking can be alleviated.
[0037] Air supply, drying, and exhaust structure of the production unit for anti-clogging honeycomb denitrification catalyst:
[0038] When the power supply is connected and the motor 61 is started, the motor 61 will drive the upper drive fan 62 to rotate. The drive fan 62 can drive the air upward and then the air carrying hot air passes through the multi-layer partition 55 on which the anti-clogging ash honeycomb denitrification catalyst is placed to achieve the drying process of the anti-clogging ash honeycomb denitrification catalyst. The moisture will be discharged upward along the exhaust hole 64 drilled on the exhaust plate 63.

[0040] Please see Figure 1-6 In this embodiment, a production device for an anti-clogging honeycomb denitrification catalyst further includes a drying and calcining structure 8 comprising a base 81 and a muffle furnace 83. The base 81 is fixedly installed on the outer ground away from the fixed seat 1, and the muffle furnace 83 is fixedly connected above the base 81. The muffle furnace 83 can be a metal box type muffle furnace that can generate a high temperature of thousands of degrees for calcination.
[0041] A heat shield 82 is movably connected to the front end of the outer wall of the muffle furnace 83. The heat shield 82 is made of pure steel metal door filled with asbestos material. The heat shield 82 can block the heat of the muffle furnace 83. A calcination chamber 84 is fixedly opened on the inner side of the muffle furnace 83. The dried anti-clogging ash honeycomb denitrification catalyst block can be placed inside the calcination chamber 84 for storage. Then, after the muffle furnace 83 is connected to the power supply and started, it can generate a high calcination temperature inside, which can accelerate the rapid molding of the anti-clogging ash honeycomb denitrification catalyst.
[0042] Working principle:
[0043] The calcination and shaping structure of the production unit for anti-clogging honeycomb denitrification catalyst:
[0044] The base 81 is fixedly set on the ground on the outer side away from the fixed seat 1. The muffle furnace 83 model can be a metal box type muffle furnace that can generate a high temperature of thousands of degrees for calcination.
