Description

Technical Field

[0001] This utility model relates to the field of quench tower technology, and specifically to a quench tower. Background Technology

[0002] In the precious metal recycling process, incineration equipment is mainly involved, as the high-temperature flue gas generated from incineration undergoes further treatment. Generally, the high-temperature flue gas first passes through an SNCR unit to remove nitrogen oxides, then passes through a heat exchanger to recover heat energy, and the resulting hot water is reused. The flue gas temperature is reduced to 550℃. Then, the high-temperature flue gas first enters a graphite quench tower for rapid cooling to below 80℃ (which can effectively suppress the formation of dioxins). After subsequent wet treatment to meet standards, the flue gas is discharged into the atmosphere through a chimney by an induced draft fan.

[0003] Impermeable graphite quench towers are commonly used for the rapid cooling of high-temperature gases (corrosive flue gas, chlorine-containing waste liquid incineration gas). The quenching principle is as follows: 1. The spray liquid vaporizes and carries away heat; 2. The graphite partition wall conducts heat and removes heat; 3. The spray liquid temperature is lower than the gas temperature, resulting in heat exchange between them. During operation, the gas and liquid flow directions are generally counter-current. The liquid is evenly sprayed down from the top of the tower through the spray device, while the gas rises evenly from the bottom. The two phases come into contact with each other through the surface of the packing material, thus transferring heat and mass. To improve spray quality, packing balls are usually filled inside the spray tank to increase the contact area between the spray liquid and the high-temperature gas. However, after a period of use, impurities such as oil and dust accumulate on the surface of the packing balls, which can easily affect the purification quality of the waste gas. Therefore, the packing balls need to be replaced. Since the packing balls are located in the middle of the spray tank at a relatively high position, unloading them is extremely inconvenient.

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] Example: Please refer to Figure 1-2 A quench tower includes a spray tank 1 equipped with spray pipes. The bottom of the spray tank 1 is connected to an exhaust gas inlet pipe. It also includes a chain drive mechanism fixed to the middle of the spray tank 1. Several support rods are fixed to the inner side of the chain 3 of the chain drive mechanism, and plastic mesh 10 is fixed to the support rods. The plastic mesh 10 divides the spray tank 1 into two parts. Several packing balls are placed on top of the plastic mesh 10. The side wall of the spray tank 1 is connected to a first chamber 2 through a notch 13. When the plastic mesh 10 is inside the first chamber 2, the packing balls will fall to the bottom of the spray tank 1. The lower part of the spray tank 1 is provided with an opening and closing door. The width of the notch 13 is smaller than the diameter of the packing balls, so when the packing balls are used for a period of time, they become sticky with... After the plastic mesh 10 is covered with oil and dust, the chain drive mechanism is activated to move it into the first chamber 2. During this process, the packing balls will fall from the plastic mesh 10 to the bottom of the spray tank 1, thus unloading the packing balls. The upper part of the spray tank 1 is equipped with a detachable observation window 11. A ladder is fixed to one side wall of the spray tank 1 at the observation window 11. The detachable method can be achieved by bolt connection. Therefore, when the old packing balls fall from the plastic mesh 10, the chain drive mechanism will reset, thus resetting the plastic mesh 10. Then, the observation window 11 can be removed, and new packing balls can be poured in through the observation window 11. This ensures the purification quality of the exhaust gas.

[0020] In this embodiment, the spray tank 1 is provided with a drive chamber 6, which is located below the first chamber 2. A motor is fixedly connected inside the drive chamber 6, and a drive sprocket 5 that meshes with the chain 3 is fixedly connected to the output end of the motor. The chain 3 passes through both the drive chamber 6 and the first chamber 2, thereby driving the chain 3. There are two chains 3, with a support rod located between the two chains 3. The motor is a dual-shaft motor, which facilitates the simultaneous driving of both chains 3. The interior of the first chamber 2 and the spray tank 1... Inside, guide rods 14 are fixedly connected to the inside of the spray tank 1 via several support rods 12. The guide rods 14 have the same direction as the chain 3. Support rods overlap the outside of the guide rods 14 to prevent the plastic net 10 from collapsing. The plastic net 10 can be fixed to the support rods with cable ties. A second chamber 9 is also connected to the side wall of the spray tank 1 away from the first chamber 2. The top of the second chamber 9 and the top of the first chamber 2 are rotatably connected by a first transition sprocket 7. A second transition sprocket 8 is provided at the bottom of the second chamber 9. The chain 3 follows... The chain 3 engages with the drive sprocket 5, the two first transition sprockets 7, and the second transition sprocket 8. The chain 3 at the bottom passes through the spray tank 1, thus achieving chain drive. The rotatable connection is as follows: a rotating shaft is fixedly connected to the spray tank 1, and the rotating shaft is rotatably connected to the first transition sprockets 7 and the second transition sprockets 8 via bearings. The lower part of the spray tank 1 has an isolation chamber 4 communicating with the first chamber 2 and the second chamber 9. The chain 3 at the bottom is located inside the isolation chamber 4, reducing the contact between the spray liquid and waste liquid. The contact range between the air and the chain 3 is increased, improving the service life of the chain 3; the drive chamber 6 effectively prevents the exhaust gas from affecting the motor; the spray tank 1 is connected to the second chamber 9 through a hole, the chain 3 passes through the hole, and the end of the guide rod 14 is in contact with the inner wall of the spray tank 1 near the second chamber 9, which helps to prevent exhaust gas leakage; and a rubber baffle 15 is fixed to the top of the notch 13, and the bottom of the rubber baffle 15 is in contact with the plastic mesh 10 to prevent the packing balls from entering the first chamber 2.

[0021] The working principle of the embodiment is as follows: After the packing balls have been used for a period of time and become covered with oil and dust, the motor starts, causing the chain 3 to move, which in turn moves the plastic mesh 10 into the interior of the first chamber 2. During this process, the packing balls fall from the plastic mesh 10 to the bottom of the spray tank 1, thereby unloading the packing balls. When the old packing balls fall from the plastic mesh 10, the motor reverses, causing the plastic mesh 10 to reset. Then, the observation window 11 is removed, and new packing balls can be poured in through the observation window 11. This ensures the purification quality of the exhaust gas.
