Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, and in particular to a quench tower device with precise control. Background Technology

[0002] Quenching towers are core equipment used in industrial production for rapidly cooling high-temperature fluids (gases or liquids), and are widely used in chemical, environmental protection, energy, and metallurgical fields (such as flue gas treatment, petroleum cracking, and reaction product cooling). Their core principle is to achieve rapid heat exchange through efficient contact between the cooling medium and the high-temperature fluid, utilizing heat conduction, convection, or phase change (such as evaporation endothermy), thereby reducing the temperature of the high-temperature fluid to the target range in a short time.

[0003] According to national standards, the heat utilization of flue gas in waste heat boilers can only reach 500℃. The flue gas must be rapidly cooled in a quench tower at a temperature between 500℃ and 200℃ to reduce the resynthesis of dioxins. The 500℃ flue gas at the outlet of the waste heat boiler will enter the quench tower, and water mist will be sprayed into the tower through spray guns, so that the high-temperature flue gas comes into direct contact with the atomized water mist, thereby cooling the flue gas. This process can prevent the resynthesis of dioxins.

[0004] The quench tower device has the following defects. In the traditional method of cooling the flue gas by using cooling water, the cooling effect is insufficient, which easily causes the quench tower to frequently experience phenomena such as wet bottom, wet walls and mud flow. Therefore, a quench tower device with precise control is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quench tower device with precise control, which aims to improve the problem of wet bottom of the quench tower caused by insufficient cooling effect in the traditional method of cooling flue gas using cooling water.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quench tower device with precise control, comprising a quench tower body and a transmission pipe, wherein the transmission pipe is fixedly connected to the left outer wall of the quench tower body, a control mechanism is provided on the transmission pipe, and an auxiliary mechanism is provided on the control mechanism, wherein the control mechanism includes an installation groove, the installation groove being opened on the inner side wall of the transmission pipe, a diversion pipe being opened on the bottom inner wall of the transmission pipe, a hollow tube being fixedly connected to the left inner wall of the quench tower body, a diversion annular pipe being fixedly connected to the left end of the hollow tube, a spray head being fixedly connected to the inner side wall of the diversion annular pipe, a rotating cover being snapped onto the top inner wall of the transmission pipe, a smoke exhaust pipe being fixedly connected to the right inner wall of the rotating cover, a lower cover being snapped onto the bottom inner wall of the transmission pipe, and a smoke inlet pipe being fixedly connected to the front inner wall of the lower cover.

[0007] As a further description of the above technical solution: the auxiliary mechanism includes a threaded groove, which is formed on the outer walls of the top and bottom sides of the transmission pipe. A rotating cover is threadedly connected to the outer wall of the side of the threaded groove. The outer wall of the side of the rotating cover is provided with a groove and a directional mark is provided on the outer wall of the top of the rotating cover.

[0008] As a further description of the above technical solution: there are three diversion pipes, which are arranged in a ring on the bottom inner wall of the transmission pipe, and the spray head is connected to the diversion pipes.

[0009] As a further description of the above technical solution: the exhaust pipe is connected to the diversion pipe, and the inlet pipe is connected to the diversion pipe.

[0010] As a further description of the above technical solution: the inner walls of the top and bottom sides of the transmission pipe are provided with annular grooves, the exhaust pipe is slidably connected to the inner wall of the side of the annular groove, and the lower cover is slidably connected to the inner wall of the side of the annular groove.

They can complete the separation or fixing of the cover and the transmission pipe by simply observing the direction indication. This facilitates the cleaning and maintenance of the inside of the device and the disassembly and replacement of individual parts, effectively reducing the high maintenance costs caused by overall replacement and lowering the operation threshold and labor costs of daily maintenance of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3This utility model provides an embodiment of a quench tower device with precise control, comprising a quench tower body 1 and a transmission pipe 2. The transmission pipe 2 is fixedly connected to the left outer wall of the quench tower body 1. A control mechanism 3 is provided on the transmission pipe 2, and an auxiliary mechanism 4 is provided on the control mechanism 3. The control mechanism 3 includes a mounting groove 31, which is formed on the inner side wall of the transmission pipe 2. A diversion pipe 33 is formed on the bottom inner wall of the transmission pipe 2. The diversion pipe 33 can divide the flue gas entering the transmission pipe 2 into multiple streams, creating conditions for subsequent precise cooling. A hollow tube 34 is fixedly connected to the left inner wall of the quench tower body 1. The left end of the hollow tube 34... A diversion annular pipe 35 is fixedly connected, which can evenly distribute the mist transported by the hollow pipe 34 to each spray head 36, ensuring that each spray head 36 supplies mist evenly. Spray heads 36 are fixedly connected to the inner side wall of the diversion annular pipe 35. The spray heads 36 spray the mist from the diversion annular pipe 35 in the form of a spray, directly cooling the flue gas in the diversion pipe 33 to achieve precise cooling. A rotating cover 37 is snapped onto the inner top wall of the transmission pipe 2. A smoke exhaust pipe 38 is fixedly connected to the inner right side wall of the rotating cover 37. A lower cover 39 is snapped onto the inner bottom wall of the transmission pipe 2. A smoke inlet pipe 310 is fixedly connected to the inner front side wall of the lower cover 39.

[0024] Reference Figures 2-4 There are three diversion pipes 33. The three diversion pipes 33 are arranged in a ring on the bottom inner wall of the transmission pipe 2. The three ring-shaped diversion pipes 33 can evenly divert the flue gas, increase the contact area with the cooling mist, and improve the cooling efficiency. The spray head 36 is connected to the diversion pipe 33, the exhaust pipe 38 is connected to the diversion pipe 33, and the inlet pipe 310 is connected to the diversion pipe 33. The inner walls of the top and bottom sides of the transmission pipe 2 are provided with annular grooves. The annular grooves provide a track for the sliding connection of the exhaust pipe 38 and the lower cover 39, ensuring smooth sliding and easy disassembly and assembly. The exhaust pipe 38 is slidably connected to the inner wall of the side of the annular groove, and the lower cover 39 is slidably connected to the inner wall of the side of the annular groove.

[0025] Reference Figures 3-4The auxiliary mechanism 4 includes a threaded groove 41, which is formed on the outer walls of the top and bottom sides of the transmission pipe 2. A rotating cover 42 is threadedly connected to the outer wall of the side of the threaded groove 41. Through the threaded connection between the rotating cover 42 and the threaded groove 41, the rotating cover 37 and the lower cover 39 can be fixed to the transmission pipe 2. The operation can be completed by rotation, which is convenient and efficient. The outer wall of the side of the rotating cover 42 has a groove 43, which increases the friction between the hand and the rotating cover 42, making it easier to grip and rotate, saving effort and preventing slippage. The outer wall of the top of the rotating cover 42 has a pointing mark 44, which indicates... The rotating cover 42 indicates the rotation direction (tightening or loosening), which helps operators quickly master the operation and improve efficiency. There are two rotating covers 42. The rotating cover 42 is rotatably connected to the outer side wall of the rotating cover 37 via a bearing. The rotating cover 42 is rotatably connected to the outer side wall of the lower cover 39 via a bearing. A frosted pad is fixedly connected to the outer side wall of the groove 43. The frosted pad further increases the friction and improves the stability when holding and rotating. A display coating is fixedly connected to the top outer wall of the indicator mark 44. The display coating makes the indicator mark 44 more conspicuous and makes it easier for operators to quickly identify the rotation direction.

[0026] Working principle: The flue gas enters the transmission pipe 2 through the inlet pipe 310 and is divided by the diversion pipe 33. Then, by opening the main body of the quench tower 1, the water-cooled mist flows through the hollow pipe 34 and into the diversion ring pipe 35. The three spray heads 36 precisely cool the flue gas in the diversion pipes 33 of different diversions, avoiding the phenomenon that the flue gas cooling efficiency is affected or incomplete when the mist is too large when the whole thing passes through, or when the mist from the spray head 36 is too small. The cooled flue gas is discharged through the exhaust pipe 38. When internal inspection, maintenance or replacement of individual parts is required, the direction of rotation is known by observing the indicator mark 44. Then, the rotating cover 42 is rotated to separate from the threaded groove 41, so that the rotating cover 37 or the lower cover 39 can be easily separated from the transmission pipe 2 for internal cleaning, maintenance or component disassembly and replacement. This reduces the maintenance cost of overall replacement and eliminates the need for professional disassembly and assembly tools for operation and adjustment.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
