Description
Technical Field
[0001] The utility model relates to the technical field of chemical equipment, in particular to an efficient graphite quencher. Background Art
[0002] The high-temperature flue gas containing hydrogen chloride gas is corrosive. Also, due to its large volume flow rate and a relatively high content of non-condensable gases, and it contains recoverable hydrogen chloride. Generally, after cooling, the effective components are recovered through a fiberglass combined absorption tower, and the non-condensable gases are discharged after the temperature is reduced to the standard. The maximum inlet temperature of the fiberglass absorption tower is 120 °C, and a corrosion-resistant quenching device is required to cool the flue gas. Quenching is a process of rapidly cooling high-temperature gas, which is the direct contact cooling of high-temperature gas with a cooling medium. In the existing quencher, the coolant is not evenly sprayed. The coolant enters through the form of punching, and the water flow is in a linear shape. Also, the existing graphite quencher has no cooling chamber. Although the pressure resistance ability is considered, there is no cooling facility on the outer wall of the graphite cylinder, which will cause the graphite wall thickness to be too high, and the outlet temperature is still higher than the tolerance temperature of the fiberglass equipment.

Detailed implementation mode
[0017] To further understand the features, technical means, specific purposes, and functions achieved by the present utility model, the following will describe the present utility model in further detail in conjunction with the accompanying drawings and specific implementation modes.
[0018] Refer to Figure 1 - Figure 2 : An efficient graphite quenching cooler, comprising a quenching cooler main body 113, wherein a steel cylinder 101 is provided inside the quenching cooler main body 113. A flue gas inlet 107 is provided at one end of the steel cylinder 101, and a flue gas outlet 108 is provided at the other end of the steel cylinder 101.

An upper pressing plate 106 for installing an upper pressing flange 105 on the cylinder upper flange 104 is provided on the cylinder upper flange 104.
[0019] High-temperature flue gas enters from the flue gas inlet 107, sequentially passes through the atomization cooling zone 200 and the efficient cooling zone 300, and finally cools down to a suitable temperature and enters the absorption tower 109 from the flue gas outlet zone 400, omitting the intermediate pipeline and cooling equipment.
[0020] Refer to Figure 1 - Figure 2 : The atomization cooling zone 200 includes an upper graphite section 201, an exhaust port 202, a cooling water inlet 203, a spray gun 204, a first baffle 205, a first sealing mechanism 500, a second sealing mechanism 600, and a third sealing mechanism 700. An upper graphite section 201 is provided inside the steel cylinder 101. An exhaust port 202 and a cooling water inlet 203 are provided on the side wall of the steel cylinder 101. A plurality of spray guns 204 penetrate through the steel cylinder 101. A plurality of vertically and horizontally interconnected holes are provided on the cylindrical wall of the upper graphite section 201. A first sealing mechanism 500, a second sealing mechanism 600, and a third sealing mechanism 700 are provided on the side wall of the steel cylinder 101.
[0021] The spray gun 204 is equipped with a nozzle, which has a spiral design. The spray guns 204 are evenly distributed at 120°. The water mist ejected by the nozzles can cover the entire cross-section. The spray gun 204 is made of special Inconel alloy steel or silicon carbide that is resistant to high temperature and corrosion. The nozzle is made of Inconel alloy steel. The liquid flow rate can be adjusted by adjusting the pressure, and the number of spray guns 204 can also be selected according to the gas flow rate. The holes provided on the upper part 201 of the graphite are evenly distributed in a circumferential manner, which can better cool the graphite cylinder wall and prevent the local temperature of the graphite cylinder wall from being too high.
[0022] Refer to Figure 2 : The second sealing mechanism 600 includes a spray gun graphite sleeve 601, a spray gun graphite sleeve steel shell nozzle flange 602, a first spray gun graphite sleeve gland 603, a second spray gun graphite sleeve gland 604 and a spray gun bottom plate 605. The spray gun bottom plate 605 is arranged on the spray gun 204. The spray gun graphite sleeve 601 is sleeved outside the spray gun 204 and is connected to the spray gun bottom plate 605 at one end close to the spray gun interface 111. The spray gun 204 is provided with a spray gun interface 111 at one end away from the steel cylinder body 101. A plurality of spray gun graphite sleeve steel shell nozzle flanges 602 are provided on the side wall of the steel cylinder body 101. The second spray gun graphite sleeve gland 604 is alternately provided with inner ring threaded holes and outer ring threaded holes. The inner ring thread is connected to the spray gun bottom plate 605, and the outer ring thread is connected to the spray gun graphite sleeve steel shell nozzle flange 602 through a long pull rod. The first spray gun graphite sleeve gland 603 is hermetically connected to the spray gun graphite sleeve steel shell nozzle flange 602 through an O-ring. An insertion pipe interface 110 is provided between the spray gun graphite sleeve steel shell nozzle flange 602 and the first spray gun graphite sleeve gland 603.
[0023] Ensure that the spray gun and related systems are turned off and the power supply is disconnected to prevent accidents during disassembly. Loosen the connection of the long pull rod. Use appropriate tools to loosen the long pull rod connecting the graphite sleeve gland 604 of the second spray gun to the pipe flange 602 of the steel shell of the spray gun graphite sleeve. This may require a wrench or special tool to loosen the nut or bolt. After loosening the long pull rod, remove the graphite sleeve gland 604 of the second spray gun from the pipe flange 602 of the steel shell of the spray gun graphite sleeve. Pay attention to keeping the parts clean and avoid damaging the threads or other connection parts. Disconnect the connection between the spray gun bottom plate 605 and the spray gun graphite sleeve 601. This may require a screwdriver or other special tool. After disconnecting the connection with the spray gun bottom plate 605, carefully slide the spray gun graphite sleeve 601 out from the outside of the spray gun 204. Since the spray gun graphite sleeve may be long and heavy, it is recommended that two people cooperate. If there is an O-ring seal connection between the first spray gun graphite sleeve gland 603 and the pipe flange 602 of the steel shell of the spray gun graphite sleeve, carefully remove the gland from the flange to avoid damaging the O-ring. This may require a thin blade or special tool to gently pry up the gland. After disassembling all parts, carefully clean each part and check for damage or wear; pay special attention to checking the integrity of the O-rings, threads and other sealing parts.
[0024] Refer to Figure 2 : The first sealing mechanism 500 includes a sight glass, a pipe flange 503 of the steel shell of the sight glass graphite sleeve, a graphite sleeve gland 504 of the sight glass, a gland 505 of the sight glass, and a glass cover plate 506. The sight glass includes a sight glass graphite sleeve 501 symmetrically arranged on the steel cylinder 101 and a sight glass high-temperature resistant quartz 502 arranged in the sight glass graphite sleeve 501. The sight glass graphite sleeve 501 is matched with the pipe flange 503 of the steel shell of the sight glass through the outer ring threaded holes provided on the gland 505 of the sight glass and is tightened and sealed by a long pull rod. The graphite sleeve gland 504 of the sight glass is tightly sealed with the pipe flange 503 of the steel shell of the sight glass through an O-ring. The inner ring of the gland 505 of the sight glass is tightly sealed with the sight glass high-temperature resistant quartz 502 by bolts.
[0025] First, it is necessary to loosen the bolts on the sight glass gland 505. These bolts are used to connect and seal the sight glass gland 505 to the flange of the nozzle of the steel shell of the sight glass graphite sleeve 503. Use appropriate tools to loosen the bolts one by one. After loosening the bolts, the sight glass graphite sleeve 501 can be removed. Note to protect the sight glass graphite sleeve during the operation to avoid damage; the sight glass graphite sleeve gland 504 is tightly sealed with the flange of the nozzle of the steel shell of the sight glass graphite sleeve 503 through an O-ring. It is necessary to carefully remove the O-ring and remove the sight glass graphite sleeve gland 504. The high-temperature resistant quartz of the sight glass 502 is tightened and sealed by the bolts inside the inner ring of the sight glass gland 505. After loosening these bolts, the high-temperature resistant quartz of the sight glass 502 can be taken out. If the sight glass graphite sleeve 501 is connected to other components, these connections need to be disconnected. After all components are disassembled, clean the contact surface and check whether all components are damaged or worn to determine whether replacement is needed. To ensure correct installation during reassembly, it is recommended to record the disassembly sequence and position, and properly store the disassembled components to avoid dust and contamination. This sealing method is convenient for maintenance and disassembly. The sight glasses are symmetrically distributed, facilitating the observation of the spray effect of the nozzles.
[0026] Refer to Figure 1 - Figure 2 : The third sealing mechanism 700 includes a graphite drain pipe steel shell nozzle flange 701, a first graphite drain pipe gland 702, a second graphite drain pipe gland 703, and a graphite drain pipe 704. The second graphite drain pipe gland 703 is provided with two circles of staggered threaded holes. The inner ring of the second graphite drain pipe gland 703 is connected to the outer pipeline. The outer ring of the second graphite drain pipe gland 703 and the graphite drain pipe steel shell nozzle flange 701 tightly seal the graphite drain pipe 704 through a long pull rod. The first graphite drain pipe gland 702 is tightly sealed with the graphite drain pipe steel shell nozzle flange 701 through an O-ring.
[0027] First, check and disconnect all external connections related to the graphite drain pipe 704, such as pipes, sensors, etc. Use a wrench or pneumatic tool to loosen the long tie rods on the outer ring of the second graphite drain pipe gland 703. These long tie rods tighten and seal the graphite drain pipe 704 on the flange of the graphite drain pipe steel shell nozzle 701. Carefully loosen the long tie rods completely and remove them for subsequent disassembly. After loosening the long tie rods, the second graphite drain pipe gland 703 can be disassembled. This may require using a screwdriver or other tools to loosen the fixing screws on the gland. Gently remove the second graphite drain pipe gland 703 from the graphite drain pipe 704 and the flange of the graphite drain pipe steel shell nozzle 701. Next, the first graphite drain pipe gland 702 needs to be disassembled. This usually involves removing the O-ring between the gland and the flange of the graphite drain pipe steel shell nozzle 701 and loosening the fixing screws on the gland. Carefully remove the first graphite drain pipe gland 702 from the flange, taking care not to damage the O-ring or other sealing elements. After disassembling all the glands, the graphite drain pipe 704 can be removed. This may require gently tapping or using a rubber mallet to assist in overcoming possible jamming, ensuring that the graphite drain pipe 704 or the surrounding sealing structure is not damaged during removal. After disassembly, use a rag and cleaner to clean all components, removing dirt and debris. Check the wear and damage of all components and perform repairs or replacements as needed. This loose flange sealing method facilitates maintenance and disassembly.
[0028] Refer to Figure 1 - Figure 2 : The high-efficiency cooling zone 300 includes a graphite heat exchange block 301, a second baffle 302, and a third baffle 303. The graphite heat exchange block 301, the second baffle 302, and several third baffles 303 are provided on the steel cylinder 101. The second baffle 302 is arranged on the steel cylinder 101. The second baffle 302 is an annular 180° steel plate and rubber gasket composite baffle. The third baffle 303 is arranged inside the steel cylinder 101 and is perpendicular to the second baffle 302.
[0029] The cooling water flows in a zigzag pattern between the graphite cylinder and the steel cylinder to improve the heat exchange effect. After the first-stage atomization cooling, the hot flue gas and the low-temperature cooling water fully conduct heat exchange in a wall-to-wall manner in the high-efficiency cooling zone 300, and the flue gas can continue to be efficiently cooled.
[0030] Refer to Figure 1 - Figure 2: The flue gas outlet area 400 includes a lower graphite section 401, a temperature measuring port 402, a cooling water outlet 403, and a drainage port 404. The wall of the steel cylinder 101 at the end close to the flue gas outlet 108 is provided with vertically and horizontally interconnected holes. The cross-sectional shape of the steel cylinder 101 at the end close to the flue gas outlet 108 is in the shape of an inserted pipe with an inclined opening. A lower graphite section 401 is provided inside the steel cylinder 101. The side wall of the steel cylinder 101 at the end close to the flue gas outlet 108 is provided with lifting lugs 112, a temperature measuring port 402, a cooling water outlet 403, and a drainage port 404.
[0031] Vertically and horizontally interconnected holes are drilled in the cylindrical wall of the lower graphite section 401, and the holes are evenly distributed in the circumference, which can better cool the graphite cylinder wall and prevent the local temperature of the graphite cylinder wall from being too high. The end of the lower graphite section 401 is processed into the shape of an inserted pipe with a certain inclined opening, which can directly penetrate into the interior of the absorption tower 109. The flue gas after sufficient cooling can directly enter the absorption tower 109 for the absorption and reuse of the effective components in the flue gas, saving the intermediate pipeline and flue gas cooling equipment.
[0032] Working principle: The high-temperature flue gas flows in from the flue gas inlet 107 and first passes through the atomization cooling area 200, where it will make reverse contact with the water mist ejected from the nozzle of the spray gun 204. Most of the heat is absorbed by using the heat of vaporization absorption of the water mist, so that the temperature of the flue gas drops rapidly. The cooled flue gas enters the high-efficiency cooling area 300 and makes staggered flow contact with the graphite heat exchange block 301 and the cooling water channels to further cool the flue gas. The cooled flue gas passes through the lower graphite section 401 and the steel cylinder 101 with an inclined cross-section at the end and enters the absorption tower 109 to absorb the effective components in the flue gas, omitting the intermediate pipeline and cooling equipment.
[0033] The above embodiments only represent one or several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
