Description

Technical Field

[0001] The utility model relates to a coking device, in particular to a gas horizontal tube primary cooler for a coke oven. Background Art

[0002] The gas cross-tube primary cooler is a specially designed heat exchange device used in the coking industry to cool and preliminarily purify high-temperature raw gas. This device not only effectively cools the gas and reduces pollutant emissions, but also optimizes resource utilization by condensing and recovering by-products such as tar. In addition, the reduction in gas temperature reduces its volume, thereby reducing the power consumption required for gas transportation and protecting subsequent processing equipment from high temperature damage.

[0003] Existing coke oven gas cross-tube primary coolers face a common challenge during operation: as the gas temperature drops, tar, naphthalene, and other condensable organic compounds condense and adhere to the tube walls, forming naphthalene deposits. This not only increases the equipment's resistance and reduces heat exchange efficiency, but can even lead to pipe blockages in severe cases, seriously impacting continuous gas production and the normal operation of the equipment. Currently, regular manual cleaning is typically used to address this naphthalene accumulation issue, but this is not only time-consuming and labor-intensive, but also increases maintenance costs and impacts production efficiency. Therefore, there is an urgent need for a self-cleaning coke oven gas cross-tube primary cooler. Utility Model Content

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1: A gas horizontal tube primary cooler for a coke oven, such as Figure 1 and Figure 2 As shown, it includes a pre-cooler body 1, an air inlet pipe 2, a first water pipe 3, an air outlet pipe 21 and a cleaning component. The pre-cooler body 1 is the core part of the entire device, providing a closed space for heat exchange between high-temperature coal gas and cooling water. The front side of the pre-cooler body 1 is connected to the air inlet pipe 2, which is used to introduce the high-temperature gas into the interior of the pre-cooler body 1. A first water pipe 3 is provided inside the pre-cooler body 1 as the main channel for cooling water circulation. Its function is to allow cooling water to flow in the pipe and effectively cool the gas by absorbing the heat of the high-temperature gas entering from the air inlet pipe 2. Both ends of the first water pipe 3 pass through the pre-cooler body 1 and extend outward to connect the water source and the water circulation system to ensure the continuous supply and circulation of cooling water. The top center of the pre-cooler body 1 is connected to the air outlet pipe 21, and the cooled gas is discharged through the air outlet pipe 21. A cleaning component is provided between the top and the interior of the pre-cooler body 1 for regularly cleaning the scale on the wall of the first water pipe 3 to avoid the cooling performance being reduced due to increased thermal resistance due to scale.

[0021] like Figure 2 and Figure 3As shown, it also includes a water pump 4, a second water pipe 41, a screw motor 5 and a water sprayer 51. The water pump 4 is installed at the left end of the top of the primary cooler body 1, which is responsible for extracting and pressurizing cooling water from the water source. The screw motor 5 is installed at the right end of the top of the primary cooler body 1. The water sprayer 51 is threadedly installed on the screw motor 5. As the power source for the cleaning process, the screw motor 5 rotates the screw to accurately control the water sprayer 51 to move up and down along the set path to ensure that it covers the entire wall of the first water pipe 3 that needs to be cleaned. The outlet end of the water pump 4 Connected to the second water pipe 41, the movable end of this telescopic hose is connected to the water sprayer 51. The water pump 4 delivers pressurized cooling water to the water sprayer 51 through the second water pipe 41. The telescopic design of the second water pipe 41 allows the water sprayer 51 to move freely during the cleaning process, ensuring that the water supply will not be interrupted even when the position of the water sprayer 51 changes, thereby maintaining a stable cleaning operation. The water sprayer 51 is equipped with ten nozzles, which can provide uniform high-pressure water flow distribution, effectively removing scale on the wall of the first water pipe 3 and enhancing the cleaning effect.

[0022] like Figure 2 As shown, guide plates 52 are also included. Three guide plates 52 are arranged inside the pre-cooler body 1. The guide plates 52 are arranged on both sides of the water sprayer 51 to guide the vertical movement of the water sprayer 51. Under the guidance of the guide plates 52, the water sprayer 51 can slide up and down smoothly and accurately in the internal space of the pre-cooler body 1, ensuring the stability and efficiency of the cleaning operation.

[0023] When gas cooling is required, first, the high-temperature gas generated by the coking oven enters the interior of the primary cooler body 1 through the air inlet pipe 2 at the front end of the primary cooler body 1. During this process, cooling water circulates through the first water pipe 3 in the primary cooler body 1, exchanges heat with the gas, and effectively reduces the gas temperature. The cooled gas is then discharged from the air outlet pipe 21 at the top center of the primary cooler body 1 and enters the subsequent processing stage. When the outer wall of the first water pipe 3 needs to be cleaned, the water pump 4 is started to draw clean water from the water source, and the clean water is transported to the sprinkler through the second water pipe 41. 51. Since the second water pipe 41 adopts a telescopic hose design, it can flexibly adapt to different position requirements inside the pre-cooler body 1. The screw motor 5 drives the sprinkler 51 to move in the vertical direction through a threaded transmission. Under the guidance of the guide plate 52, the sprinkler 51 can slide up and down smoothly inside the pre-cooler body 1, ensuring that clean water is evenly sprayed on the wall of the first water pipe 3, effectively removing accumulated tar, dust and other impurities, thereby avoiding increasing the resistance of the equipment, maintaining heat exchange efficiency, preventing pipeline blockage, and ensuring the continuous production of gas and the normal operation of the equipment.

[0024] Example 2: Based on Example 1, Figure 1 and Figure 2As shown, it also includes a clip 31, a baffle 32 and a first handle 33. Four clips 31 are symmetrically installed on both sides of the pre-cooler body 1. The clips 31 fit tightly against the outer wall of the first water pipe 3. The two ends of the first water pipe 3 are firmly fixed to the pre-cooler body 1 by fixing bolts. A first handle 33 is provided between the two clips 31. A baffle 32 is provided at the lower part of the first handle 33. The baffle 32 usually closes the drain outlet at the bottom of the pre-cooler body 1 to prevent cooling water leakage; after completing the cleaning operation, when it is necessary to discharge the cleaning water and impurities, the operator should first remove the fixing bolts to unlock the clips 31 on both sides, and then lift the baffle 32 by pulling the first handle 33 to open the drain outlet at the lower part of the pre-cooler body 1, so that the internal cleaning water and impurities can be discharged smoothly, completing the entire drainage process.

[0025] like Figure 2 As shown, it also includes a charging box 6, a filter 61 and a second handle 62. A charging box 6 is provided at the lower part of the pre-cooler body 1, and a filter 61 is provided on the top of the charging box 6. The filter 61 is provided below the water sprayer 51. During the cleaning process, the high-pressure water flow sprayed by the water sprayer 51 will wash away the impurities on the wall of the first water pipe 3, and these impurities will then fall into the charging box 6 at the lower part of the pre-cooler body 1. The filter 61 performs preliminary filtration on the fallen impurities, effectively intercepts larger particles, and prevents them from entering the circulating water system, thereby protecting the pump and other components from damage. A second handle 62 is provided on the left side of the charging box 6. The operator can easily pull the charging box 6 out of the pre-cooler body 1 by pulling the second handle 62, so that the impurities can be easily cleaned and the charging box 6 can be thoroughly cleaned, ensuring the hygiene and efficient operation of the entire system.

[0026] Impurities generated during the cleaning process will fall into the charging box 6 at the bottom of the pre-cooler body 1. The filter 61 on the top of the charging box 6 will perform preliminary filtration on the impurities to prevent larger particles from entering the circulation system. After the cleaning operation is completed, the buckles 31 on both sides are unlocked by removing the fixing bolts. Then, the first handle 33 is pulled to lift the baffle 32 to open the drain port at the bottom of the pre-cooler body 1, so that the cleaning water and impurities can be discharged. Finally, by pulling the second handle 62, the charging box 6 can be easily removed for further cleaning and maintenance.
