[0026] The specific embodiment is described below in conjunction with the accompanying drawings.

[0027] EMBODIMENT

[0028] As Figures 1 to 8 shown, in the embodiment, a kind of flue gas cooling device of glass kiln is mainly disclosed, including box 1, box 1 is equipped with the baffled flue 10 of being formed by water cooling plate 11, water cooling plate 11 both ends are equipped with water inlet hole and water outlet hole respectively, box 1 top end is connected with the gas inlet pipe 12 being communicated with the middle part of baffled flue 10, box 1 both sides are connected with the gas outlet pipe 13 being communicated with the end of baffled flue 10, box 1 is communicated with ash collection bin 2 below baffled flue 10.Specifically, gas inlet pipe 12 is communicated with the flue of glass kiln, gas outlet pipe 13 is connected with subsequent flue gas treatment equipment, and constitutes flue gas treatment system.Water cooling plate 11 is hollow heat exchange plate, can be integrally formed with box 1, water inlet hole and water outlet hole are located on the opposite two end faces of box 1, for connecting circulation cooling water.Through the arrangement of water cooling plate 11 inside box 1, baffled flue 10 for cooling flue gas is formed, flue gas flow path is lengthened, flue gas is forced to change flow direction, increases the contact time with water cooling plate 11, intensifies turbulent effect, significantly improves heat exchange efficiency, prolongs the service life of the device and subsequent flue gas treatment equipment.In the process of flue gas baffling, gravity promotes large-particle dust to settle along the surface of water cooling plate 11, falls into ash collection bin 2, reduces the risk of dust accumulation in flue, reduces the probability of blockage, prolongs the continuous operation cycle of equipment.

[0029] Furthermore, in a specific implementation, the ash collection bin 2 provided in this utility model embodiment is provided with an upward-opening insertion door 3. The upward-opening insertion door 3 includes a slider 31, a rotating shaft 32, and a door panel 33. The slider 31 is horizontally slidably connected to the slide rails 14 provided on both sides of the box body 1. The rotating shaft 32 is connected between the sliders 31 on both sides. The door panel 33 is rotatably connected to the rotating shaft 32. The slide rails 14 are provided between the baffle flue 10 and the ash collection bin 2, and the gap between the slide rails 14 and the baffle flue 10 can be used to insert the door panel 33 to isolate the baffle flue 10 from the ash collection bin 2. Specifically, when the upward-opening insertion door 3 is in the closed state, it isolates the gas exchange between the box 1 and the outside world, and the lower end of the baffle channel is connected to the ash collection bin 2 for continuous ash collection. When the ash in the ash collection bin 2 needs to be cleaned, the door panel 33 is first opened up to make the door panel 33 horizontal, and then the door panel 33 is moved horizontally and inserted into the box 1. At this time, the door panel 33 isolates the baffle flue 10 from the ash collection bin 2, reducing the leakage of flue gas in the flue gas treatment system and the backflow of external air, which would cause pressure fluctuations inside the kiln and ensure the stability of production. There is no need to shut down the entire machine or disassemble the flue, thus avoiding production interruption.

[0030] Furthermore, in specific implementation, such as Figures 4 to 6 As shown, the inner wall of the housing 1 provided in this embodiment of the present invention is provided with a limiting block 15 that abuts against the slider 31 to restrict the outward movement of the slider 31. Specifically, the limiting block 15 is located above one end of the slide rail 14. The limiting block 15 defines the outward movement boundary of the slider 31, while the inner wall of the housing 1 defines the inward movement boundary of the slider 31. It should be noted that when the slider 31 abuts against the limiting block 15, it ensures that the end of the slide rail 14 does not interfere with the rotation of the door panel 33, allowing the door panel 33 to be freely flipped up and down, while avoiding mechanical damage or personnel safety hazards caused by the door panel 33 accidentally falling off or being over-opened. In addition, when the slider 31 abuts against the inner wall of the housing 1 at the limit position of inward movement, a portion of the door panel 33 is still outside the housing 1, which facilitates the operation of the door panel 33, while ensuring that most of the channel between the baffle flue 10 and the ash collection bin 2 can be isolated.

[0031] Furthermore, in specific implementation, such as Figures 4 to 6 As shown in the embodiment of this utility model, the end face of the ash collection bin 2 is provided with a cleaning bin opening 20 that cooperates with the stepped door panel 33. Specifically, the cleaning bin opening 20 includes four stepped surfaces, with the upper stepped surface facing inward and the two side and lower stepped surfaces facing outward, effectively limiting the excessive rotation of the door panel 33. The stepped cooperation between the door panel 33 and the cleaning bin opening 20 forms a labyrinth seal, reducing dust leakage and air infiltration, and maintaining stable negative pressure in the system.

[0032] Furthermore, in a specific implementation, a sealing strip is provided along the outer edge of the ash removal chamber opening 20 provided in this embodiment of the present invention. Specifically, the sealing strip can be made of high-temperature resistant silicone material to ensure long-term sealing reliability.

[0033] Further, in specific implementation, the door plate 33 is provided with a transparent observation window, which facilitates the operator to directly view the dust accumulation state in the dust collecting bin 2 through the observation window, accurately determine the dust cleaning time, and avoid the risk of equipment overload.

[0034] Further, in specific implementation, as shown in Figure 1 , Figures 4 to 6 A handle 34 is installed on the outer plate surface of the door plate 33. Specifically, the handle 34 is externally located and the surface is coated with heat insulation material, which can still be safely held even in a high temperature environment.

[0035] Further, in specific implementation, as shown in Figure 3 The cross section of the baffle flue 10 is W-shaped. Specifically, the baffle flue 10 can be arranged by six water-cooled plates 11, the middle baffle position is communicated with the air inlet pipe 12, the flue gas is uniformly distributed to two flue gas treatment devices, and the working load of the flue gas treatment device is reduced. The lower baffle position is communicated with the dust collecting bin 2. In order to avoid the formation of vortex in the dust collecting bin 2 and reduce dust raising, a louver inclined plate can be further installed at the lower baffle position, which is inclined towards the outer wall of the box body 1.
