Abstract
Description
Technical Field
[0001] This utility model relates to the field of calcium carbide furnace gas purification technology, and is a precise positioning device for ash blockage in a calcium carbide furnace purification system. Background Technology
[0002] The calcium carbide furnace purification system operates by reducing the temperature of the furnace gas (normally below 850℃) to below 600℃ in a primary settling chamber. The cooled gas then passes through a secondary settling chamber and an air-cooling chamber for further settling and cooling, reducing the temperature to below 320℃ and removing large particles of dust. The gas, now below 320℃, is then sent to a baghouse for further dust collection. After dust collection, the gas is sent to the main gas pipeline. Dust collected in the primary, secondary, and baghouse chambers is discharged via an ash discharge valve into a scraper conveyor, which then transports it to an ash storage silo. From there, it is transported by ash trucks to a solid waste treatment plant for disposal. Currently, in existing calcium carbide furnace purification systems, when ash blockage occurs in any chamber, operators typically use hammers to tap the chambers. This method not only makes it difficult to determine the extent of blockage but also easily damages the chambers. Since the medium inside the chambers contains CO gas and dust, the tapping can easily generate sparks, potentially causing an explosion.
[0003] Therefore, existing calcium carbide furnace purification systems often experience difficulties in operation due to ash blockage in the silo, which prevents the fan from drawing out the ash and makes operation difficult. In addition, the location of the ash blockage cannot be accurately located in the ash-blocking silo, affecting calcium carbide furnace production. Summary of the Invention
[0004] This utility model provides a precise ash-blocking positioning device for a calcium carbide furnace purification system, which overcomes the shortcomings of the prior art.

Detailed Implementation
[0016] This utility model is not limited to the following embodiments, and the specific implementation method can be determined according to the technical solution of this utility model and the actual situation.
[0017] Unless otherwise specified, all equipment and devices used in this invention are existing and commonly known in the art. For example, the pressure detector 23, dust analyzer 42, and gas analyzer 43 are existing and commonly known equipment.
[0018] In this utility model, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as the positional relationships of front, back, top, bottom, left, and right, which are based on the instructions attached. Figure 1 The orientation of the layout is determined by the direction of the map.
[0019] The present invention will be further described below with reference to the embodiments and accompanying drawings:
[0020] Example 1: As shown in the attached document Figure 1As shown, the precise ash-blocking positioning device of the calcium carbide furnace purification system includes a calcium carbide furnace 1, a primary settling chamber 2, a secondary settling chamber 3, an air-cooled chamber 4, a coarse gas blower 5, a primary bag filter 6, a clean gas blower 9, and a nitrogen main pipe 10. A furnace gas inlet pipeline 11 is fixedly connected between the furnace gas outlet of the calcium carbide furnace 1 and the lower inlet of the primary settling chamber 2. A first treatment pipeline 12 is fixedly connected between the top outlet of the primary settling chamber 2 and the lower inlet of the secondary settling chamber 3. A second treatment pipeline 13 is fixedly connected between the top outlet of the secondary settling chamber 3 and the lower inlet of the air-cooled chamber 4. A third treatment pipeline 14 is fixedly connected between the top outlet of the air-cooled chamber 4 and the inlet of the coarse gas blower 5. A fourth treatment pipeline 15 is fixedly connected between the outlet of the coarse gas blower 5 and the lower inlet of the primary bag filter 6. A fifth processing pipeline 16 is fixedly connected between the outlet of the gas purifier and the inlet of the gas purifier 9. A furnace gas outlet pipeline 17 is fixedly connected to the outlet of the gas purifier 9. A first nitrogen test plug pipeline 18, a second nitrogen test plug pipeline 19, a third nitrogen test plug pipeline 20, and a fourth nitrogen test plug pipeline 21 are fixedly connected to the bottom inlet of the first-stage bag filter 6, the bottom inlet of the air-cooled silo 4, the bottom inlet of the second-stage settling silo 3, and the bottom inlet of the first-stage settling silo 2, respectively. A fifth nitrogen test plug pipeline 22 is fixedly connected to the top outlet of the first-stage bag filter 6 and the furnace gas outlet pipeline 17. A pressure detector 23 and a pressure relief valve 24 are sequentially installed on the furnace gas outlet pipeline 17 to the right of the fifth nitrogen test plug pipeline 22. A high-temperature inlet valve 25 is installed on the furnace gas inlet pipeline 11.
[0021] In this invention, the high-temperature furnace gas (temperature below 850℃) output from the calcium carbide furnace 1 is cooled by settling in the first-stage settling chamber 2, and the furnace gas temperature drops to below 600℃. After settling and cooling in the second-stage settling chamber 3 and the air-cooled chamber 4, the furnace gas temperature drops to 320℃, removing large particles of dust. Then, the coarse gas blower 5 sends the furnace gas with the temperature reduced to below 320℃ to the first-stage bag filter chamber 6 for further dust removal. The dust-removed furnace gas is then sent to the subsequent main gas pipeline through the furnace gas outlet pipeline 17.
[0022] When ash blockage occurs during operation, this utility model closes the high-temperature inlet valve 25 and the venting and pressure relief valve 24. Nitrogen is then used to sequentially check the blockage chambers of the primary bag filter silo 6, air-cooled silo 4, secondary settling silo 3, and primary settling silo 2. Specifically: First, the primary bag filter silo 6 is checked. Nitrogen is supplied to the primary bag filter silo 6 via the nitrogen main pipe 10 and the first nitrogen test blockage line 18, and then to the furnace gas outlet line 17 via the fifth nitrogen test blockage line 22. The pressure is detected by the pressure detector 23 on the furnace gas outlet line 17. When the pressure rises, it indicates that the primary bag filter silo 6 is unobstructed and not blocked. Pressure is then released through the venting and pressure relief valve 24 on the furnace gas outlet line 17. After depressurization, close the venting valve 24. Next, inspect the air-cooled chamber 4. Send nitrogen from the second nitrogen test plugging pipeline 19 to the air-cooled chamber 4 and the first-stage bag filter chamber 6, and then send it from the fifth nitrogen test plugging pipeline 22 to the furnace gas outlet pipeline 17. The pressure is detected by the pressure detector 23 on the furnace gas outlet pipeline 17. When the pressure rises, it indicates that the air-cooled chamber 4 is also unobstructed and not blocked with ash. Depressurize through the venting valve 24 on the furnace gas outlet pipeline 17. After depressurization, close the venting valve 24. Finally, inspect the second-stage settling chamber 3 and the first-stage settling chamber 2 in sequence until the blocked chamber is found and cleaned.
[0023] This utility model, through the addition of a nitrogen main pipe 10 and the cooperation of various nitrogen test plugging pipelines, can accurately locate the ash-blocked silo, clean the ash-blocked silo in a timely manner, effectively shorten the ash-blocking treatment time, reduce the treatment cost, improve the operating efficiency of the device, and does not affect the normal production process of the calcium carbide furnace 1.
[0024] The above-mentioned precise positioning device for ash blockage in the calcium carbide furnace purification system can be further optimized and / or improved according to actual needs:
[0025] Example 2: Its difference from Example 1 is as follows: (See attached) Figure 1As shown, it also includes a secondary bag filter hopper 7 and a tertiary bag filter hopper 8. A sixth treatment pipeline 26 is fixedly connected between the fourth treatment pipeline 15 and the lower inlet of the secondary bag filter hopper 7. A seventh treatment pipeline 27 is fixedly connected between the sixth treatment pipeline 26 and the lower inlet of the tertiary bag filter hopper 8. An eighth treatment pipeline 28 is fixedly connected between the fifth treatment pipeline 16 and the top outlet of the secondary bag filter hopper 7. A ninth treatment pipeline 29 is fixedly connected between the fifth treatment pipeline 16 (between the eighth treatment pipeline 28 and the air purifier 9) and the top outlet of the tertiary bag filter hopper 8. A first nitrogen test plugging... A sixth nitrogen test plugging pipeline 30 is fixedly connected between the nitrogen main pipe 10 on the right side of pipeline 18 and the bottom inlet of the secondary bag filter 7. A seventh nitrogen test plugging pipeline 31 is fixedly connected between the nitrogen main pipe 10 on the right side of the sixth nitrogen test plugging pipeline 30 and the bottom inlet of the tertiary bag filter 8. An eighth nitrogen test plugging pipeline 32 is fixedly connected between the top outlet of the secondary bag filter 7 and the fifth nitrogen test plugging pipeline 22. A ninth nitrogen test plugging pipeline 33 is fixedly connected between the fifth nitrogen test plugging pipeline 22 on the right side of the eighth nitrogen test plugging pipeline 32 and the top outlet of the tertiary bag filter 8.
[0026] During operation, the primary bag filter silo 6, the secondary bag filter silo 7, and the tertiary bag filter silo 8 can be used simultaneously, or two can be used at a time, or they can be used individually. This configuration facilitates maintenance and does not affect the normal operation of the process. If all bag filter silos are in use, and ash blockage occurs during operation, the blockage should be located in the following order: tertiary bag filter silo 8, secondary bag filter silo 7, air-cooled silo 4, secondary bag filter silo 7, and primary bag filter silo 6. The principle is to start by checking the silo closest to the furnace gas outlet pipeline 17.
[0027] Example 3: Its difference from Example 2 is as follows: (See attached) Figure 1 As shown, the bottom of the primary settling chamber 2, the secondary settling chamber 3, the air-cooled chamber 4, the primary baghouse 6, the secondary baghouse 7, and the tertiary baghouse 8 are all equipped with vibration motors.
[0028] During use, the vibration motor vibrates each compartment to promptly remove accumulated dust.
[0029] Example 4: It differs from Examples 2 to 3 in that: as shown in the appendix Figure 1 As shown, a first nitrogen replacement pipeline 35 is fixedly connected between the nitrogen main pipe 10 on the right side of the seventh nitrogen test plug pipeline 31 and the upper inlet of the first-stage bag filter 6. A second nitrogen replacement pipeline 36 is fixedly connected between the first nitrogen replacement pipeline 35 and the upper inlet of the second-stage bag filter 7. A third nitrogen replacement pipeline 37 is fixedly connected between the first nitrogen replacement pipeline 35 on the right side of the second nitrogen replacement pipeline 36 and the upper inlet of the third-stage bag filter 8. A venting treatment pipeline 38 is fixedly connected to the furnace gas outlet pipeline 17 on the right side of the pressure detector 23.
[0030] During operation, when maintenance is required, nitrogen is used to replace the primary bag filter 6, secondary bag filter 7, and tertiary bag filter 8. The replacement steps for the primary bag filter 6 are as follows: nitrogen is sent to the primary bag filter 6 through the nitrogen main pipe 10 and the first nitrogen replacement pipeline 35, and then sent to the subsequent venting chimney for combustion treatment through the fifth treatment pipeline 16, the furnace gas outlet pipeline 17, and the venting treatment pipeline 38. The replacement steps for the secondary bag filter 7 and the tertiary bag filter 8 are the same.
[0031] Example 5: It differs from Example 4 in that, as shown in the attached document... Figure 1 As shown, a furnace gas circulation pipeline 39 is fixedly connected between the furnace gas outlet pipeline 17 and the furnace gas inlet pipeline 11 on the right side of the corresponding venting pipeline 38.
[0032] During use, furnace gas with a temperature below 320°C is sent from furnace gas circulation pipeline 39 to furnace gas inlet pipeline 11, where it mixes with high-temperature furnace gas (temperature below 850°C) sent from calcium carbide furnace 1 to reduce the temperature of the furnace gas.
[0033] Example 6: Its difference from Examples 2 to 5 is as follows: (See attached) Figure 1 As shown, temperature displays 40 are installed on the first processing pipeline 12 and the third processing pipeline 14. A dust analyzer 42 is installed on the fifth processing pipeline 16 between the ninth processing pipeline 29 and the clean air blower 9. A gas analyzer 43 is installed on the furnace gas outlet pipeline 17 between the clean air blower 9 and the fifth nitrogen test plug pipeline 22. A temperature display 40 and a pressure display 41 are installed on the furnace gas circulation pipeline 39.
[0034] During use, dust in the furnace gas is detected by dust analyzer 42, CO, H2 and O2 content in the furnace gas is detected by gas analyzer 43, and temperature and pressure are monitored in real time by temperature display 40 and pressure display 41.
[0035] Example 7: It differs from Examples 2 to 6 in that: as shown in the appendix Figure 1 As shown, the bottom outlets of the primary settling bin 2, secondary settling bin 3, air-cooled bin 4, primary bag filter bin 6, secondary bag filter bin 7 and tertiary bag filter bin 8 are all fixedly connected to ash discharge pipelines 34. A chain conveyor 45 is provided below each ash discharge pipeline 34, and an ash discharge bin 46 is provided below the left side of the chain conveyor 45.
[0036] During use, the ash accumulated in each bin is sent to the chain conveyor 45 through the ash discharge pipeline 34 of each bin, and then sent to the ash discharge bin 46 by the chain conveyor 45.
[0037] Depending on the needs, the pipelines and equipment of the ash-blocking precision positioning device of the calcium carbide furnace purification system can also be equipped with conventional valves, thermometers and pressure gauges known and commonly used in the field, according to production requirements.
[0038] The above technical features constitute the embodiments of this utility model, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
[0039] The usage process of this utility model embodiment:
[0040] First, the high-temperature furnace gas below 850°C from the calcium carbide furnace 1 is sequentially sent to the primary settling chamber 2, the secondary settling chamber 3, and the air-cooled chamber 4 via the furnace gas inlet pipeline 11 for settling and cooling treatment, resulting in furnace gas with a temperature below 320°C and removal of large particulate dust. Then, the furnace gas with a temperature reduced to below 320°C is sequentially sent to the primary bag filter chamber 6, the secondary bag filter chamber 7, and the tertiary bag filter chamber 8 for further dust removal by the coarse air blower 5. The dust-removed furnace gas is then sent to the subsequent main gas pipeline via the fifth treatment pipeline 16 and the furnace gas outlet pipeline 17. Finally, the ash accumulated in each chamber is sent to the chain conveyor 45 via the ash discharge pipeline 34, and then to the ash discharge chamber 46 via the chain conveyor 45.
[0041] When ash blockage occurs during operation (all three baghouses – primary baghouse 6, secondary baghouse 7, and tertiary baghouse 8 – are in use), close the high-temperature inlet valve 25 and the venting and pressure relief valve 24. Use nitrogen to sequentially check the blocked baghouses in the following order: First, check the tertiary baghouse 8. Nitrogen is supplied to the tertiary baghouse 8 via the main nitrogen pipe 10 and the seventh nitrogen test line 31. Then, it is supplied to the furnace gas outlet line 17 via the ninth nitrogen test line 33 and the fifth nitrogen test line 22. The pressure is detected by the pressure detector 23 on the furnace gas outlet line 17. When the pressure rises, it indicates that the tertiary baghouse 8 is clear and not blocked. The pressure is then released through the venting valve on the furnace gas outlet line 17. Pressure relief valve 24 is used to release pressure. After the pressure release is completed, pressure relief valve 24 is closed. Next, the secondary bag filter silo 7 is checked. Nitrogen gas is sent to the secondary bag filter silo 7 through the sixth nitrogen gas test plugging pipeline 30, and then sent to the furnace gas outlet pipeline 17 through the eighth nitrogen gas test plugging pipeline 32 and the fifth nitrogen gas test plugging pipeline 22. The pressure is detected by the pressure detector 23 on the furnace gas outlet pipeline 17. When the pressure rises, it indicates that the air-cooled silo 4 is unobstructed and not blocked with ash. Pressure is released through pressure relief valve 24 on the furnace gas outlet pipeline 17. After the pressure is released, pressure relief valve 24 is closed. Finally, the primary bag filter silo 6, air-cooled silo 4, secondary settling silo 3 and primary settling silo 2 are checked in sequence until the blocked silo is found. The blocked silo is vibrated by the vibration motor on the right side of the bottom of the silo and the ash is cleaned in time.
