Description

Technical Field

[0001] This utility model relates to a high-efficiency rapid cooling device for flue gas. Background Technology

[0002] Currently, the cement industry is widely using solid and hazardous waste as alternative fuels to reduce raw coal consumption and carbon emissions, thereby contributing to the achievement of "dual carbon" targets. These alternative fuels often contain high concentrations of K₂O, Na₂O, SO₃, and Cl₂. - Volatile components, such as alkali, sulfur, and chlorine, are easily accumulated in the flue gas. The accumulation of these volatile components can lead to crusting and blockage in the cement kiln system. Excessive alkali, sulfur, and chlorine content in the clinker will affect its quality. A bypass venting system is typically used to remove some of these volatile components, requiring a quenching device to rapidly cool the flue gas.

[0003] Most flue gas quenching devices currently on the market have low cooling efficiency, are highly susceptible to thermal stress, and suffer from uneven flue gas temperature mixing, easily leading to localized high temperatures. Furthermore, existing flue gas quenching devices are inconvenient for operators to disassemble and clean, increasing their workload. Utility Model Content

The first slide rail is provided with a first slider, and a lifting plate is installed at one end of the first slider. A positioning plate is installed at the bottom end of the lifting plate.

[0017] By adopting the above technical solution, the lifting plate can be raised and lowered inside the first slide rail through the cooperation of the first slide rail and the first slider.

[0018] In a preferred embodiment of the flue gas high-efficiency rapid cooling device of this utility model, a first high-pressure spring is installed at the top of the first groove, and the bottom end of the first high-pressure spring is fixedly connected to the top of the lifting plate.

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0037] Example 1: Refer to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a high-efficiency flue gas rapid cooling device, which can achieve rapid temperature drop, with a rapid cooling time of less than 0.5s, reduce the impact of thermal stress on the equipment, and facilitate operation and maintenance by operators. The device includes a quench box 1, which includes a mounting base 101. The mounting base 101 is fixedly installed at the bottom of the quench box 1. A discharge pipe 1011 is installed inside the mounting base 101. A filter assembly 102 is installed inside the mounting base 101. A first welding plate 103 and a second welding plate 109 are installed on the outer wall of the quench box 1.

An internal thread 1012 is provided on the inner wall of the mounting base 101. A smoke exhaust pipe 112 is installed at the top of the quench box 1. A guide plate 111 is installed at the bottom of the interior of the quench box 1. A cooling fan 113 is installed on the side wall of the quench box 1.

[0038] A coolant pump 105 is installed at the top of the coolant tank 104, and a delivery pipe 106 connected to the coolant pipe 107 is installed at the output end of the coolant pump 105.

The water inside the water spray pipe 10101 is sprayed out through the nozzles.

[0039] The outer wall of the coolant pipe 107 is equipped with heat dissipation fins 108. Through the design of the heat dissipation fins 108, the heat absorbed inside the coolant pipe 107 can be quickly dissipated.

[0040] The specific working principle is as follows: when rapid heat dissipation of the quench box 1 is required, the coolant pump 105 is first started to drive the coolant inside the coolant tank 104 to enter the coolant pipe 107 through the delivery pipe 106. The coolant pipe 107 is then arranged in a ring around the outer wall of the quench box 1, thereby improving the heat dissipation effect of the coolant pipe 107 on the quench box 1. At the same time, the heat dissipation fins 108 are designed to quickly dissipate the heat absorbed by the coolant pipe 107, thereby improving the heat dissipation effect of the quench box 1. Simultaneously, the water spray pipe 10101 drives the water inside the water tank body 1010 to spray out quickly to dissipate the flue gas inside the quench box 1, thereby achieving a rapid temperature drop with a quenching time of less than 0.5 seconds, reducing the impact of thermal stress on the equipment.

[0041] Example 2: Refer to Figures 1-5 This is the second embodiment of the present invention. This embodiment provides a high-efficiency flue gas quenching device, which can overcome the problem that most flue gas quenching devices on the market, when circulating cooling water for a long time, are prone to generating heat in the cooling water, thus affecting the heat dissipation effect of the high-efficiency flue gas quenching device. At the same time, existing flue gas quenching devices are inconvenient for operators to disassemble and clean, thus increasing the labor intensity of operators. It includes a positioning and fixing mechanism 2, which includes a mounting frame 201. The mounting frame 201 is fixedly installed on the outer wall of the mounting base 101. A hinge plate 202 is hinged inside the mounting frame 201, and a limit rod 204 is installed at one end of the hinge plate 202. A second high-pressure spring 203 is installed at one end of the hinge plate 202, and one end of the second high-pressure spring 203 is fixedly connected to the side wall of the mounting base 101. Through the design of the first high-pressure spring 1018, the lifting plate 1016 is driven to reciprocate up and down by the elastic recovery of the first high-pressure spring 1018.

[0042] The outer wall of the filter assembly 102 is provided with external threads 1021, and the external threads 1021 are threadedly connected with the internal threads 1012. The outer wall of the filter assembly 102 is provided with positioning grooves 1022. The inner wall of the filter assembly 102 is provided with limiting blocks 1023, and the top of the limiting block 1023 is provided with a filter screen body 1024, which is threadedly connected with the internal threads 1012 through the external threads 1021, so as to facilitate the installation and removal of the filter assembly 102 from the mounting base 101 by rotating the filter assembly 102.

[0043] The bottom end of the discharge pipe 1011 is provided with a first groove 1013, and the inner wall of the first groove 1013 is provided with a first slide rail 1014. The first slide rail 1014 is provided with a first slider 1015, and a lifting plate 1016 is installed at one end of the first slider 1015. A positioning plate 1017 is installed at the bottom end of the lifting plate 1016. A first high-pressure spring 1018 is installed at the top end of the first groove 1013, and the bottom end of the first high-pressure spring 1018 is fixedly connected to the top end of the lifting plate 1016. Through the design of the first high-pressure spring 1018, the lifting plate 1016 is driven to reciprocate up and down by the elastic recovery of the first high-pressure spring 1018.

[0044] The specific working principle is as follows: when the filter assembly 102 needs to be installed and disassembled, it is first connected by the internal thread 1012 and the external thread 1021, which facilitates quick disassembly of the filter assembly 102 from the mounting base 101 by rotating it. At the same time, the positioning groove 1022 and the limiting rod 204 are engaged with each other, and the hinge plate 202 is hinged to the mounting frame 201. By pressing one end of the hinge plate 202, the second high-pressure spring 203 is deformed, causing the other end of the hinge plate 202 to lift up, which drives the limiting rod 204 to no longer be engaged with the positioning groove 1022, thereby facilitating the positioning and fixing of the filter assembly 102. At the same time, through the design of the filter screen body 1024, and by disassembling the filter assembly 102 to disassemble and clean the filter screen body 1024, the filtration effect of the filter screen body 1024 is improved.
