The tank body 2 is driven to rotate in a mode of driving by the motor 42 and gear transmission, the structure is simple, installation interference is avoided, and the operability is high.
Further, as shown in fig. 1, the spraying system 3 further includes a water storage device 32, a water pump 33 and a water pipe 34; the water storage device 32 and the water pump 33 are both arranged outside the cavity surrounded by the upper tank body 1 and the lower tank body 2; the water storage device 32 and the water pump 33 are respectively communicated with the first spraying array 30 and the second spraying array 31 through water pipes 34. By adopting the structure, the first spraying array 30 and the second spraying array 31 share the same water supply pipeline (the water supply pipeline is composed of the water storage device 32, the water pump 33 and the water pipe 34), the structure of the water supply pipeline is simplified, and the layout of the water pipe 34 is simpler and easier to maintain. Meanwhile, as the first spraying array 30 and the second spraying array 31 are generally required to be synchronously sprayed, the structure can be used for setting valves on the main pipeline, so that the synchronous spraying control of the first spraying array 30 and the second spraying array 31 is conveniently realized.
By adopting the flue gas pre-dedusting spray tank 01 for the preheating furnace, the cooling water sprayed by the first spray array 30 is not in direct contact with high-temperature flue gas, so that the components of the cooling water sprayed by the first spray array 30 are not polluted. And the cooling water sprayed by the second spray array 31 is sewage containing dust. Directly collecting two paths of cooling water leads to the increase of sewage quantity and increases the treatment burden for solid-liquid separation in the subsequent lower tank body 2, and aiming at the technical problem, as shown in figure 1, the upper tank body 1 comprises a partition plate 11; the partition plate 11 is respectively fixedly connected with the side wall of the upper tank body 1 and the side wall of the flue pipeline 10, and the partition plate 11 separates the upper tank body 1 into an upper chamber 001 and a lower chamber 002; a first water outlet 12 is formed on the lower side wall of the upper chamber 001. The cooling water sprayed by the first spray array 30 flows in the upper chamber 001 and is finally discharged through the first water outlet 12. Through the arrangement, the recycling of the cooling water sprayed out of the first spraying array 30 is realized, the water pollution and the water waste are reduced, the water resource is saved, and the treatment burden is reduced for the subsequent solid-liquid separation in the lower tank body 2.
Since the water discharged from the first water outlet is not polluted, the water can be directly recycled, and further, as shown in fig. 1, the first water outlet 12 is communicated with the water storage device 32. Through the structure, the water outlet of the first water outlet 12 is directly recycled to the water storage device 32, so that the water consumption of the flue gas pre-dedusting spraying tank 01 for the preheating furnace is greatly reduced.
In order to obtain a good settling effect, the slag discharge valve 20 is normally set to a closed state when the lower tank 2 is rotated. Therefore, when the solid dust slag at the bottom of the lower tank body 2 accumulates to a certain amount, the small opening end of the lower tank body 2 may be blocked, which is specifically indicated that the solid dust slag cannot be smoothly discharged. In order to solve the technical problem, as shown in fig. 1, an ultrasonic vibration device 22 is disposed on the outer wall of the lower tank 2; the ultrasonic vibration device 22 is arranged near the small end of the lower tank body 2. Through setting up ultrasonic vibration device 22, can carry out high-speed vibration to the awl fill portion outer wall of the lower jar of body 2 and handle, help solid-state dust material sediment particle to break away from awl fill portion outer wall, the solid-state dust material sediment particle homodisperse of help caking to help solid-state dust material sediment to be discharged by the osculum end of the lower jar of body 2 smoothly. The working principle is as follows: the sound pressure sharp change of the ultrasonic wave generated by the ultrasonic vibration device 22 when the ultrasonic wave is transmitted in the liquid generates strong cavitation and emulsification phenomena, millions of tiny cavitation bubbles are generated every second, the bubbles are rapidly generated in large quantity under the action of the sound pressure and are continuously and violently blasted to generate strong impact force and negative pressure suction force, so that the stubborn solid dust slag particles can be stripped from the outer wall of the cone part, and the agglomerated solid dust slag particles are uniformly dispersed.
Since the water discharge pipe 21 is moved circumferentially when the lower tank 2 is rotated, the water discharge pipe 21 cannot be connected to an external device or a pipeline. That is, it is necessary to ensure that the lower tank 2 is in a stationary state to dock the drain pipe 21 with external equipment or piping. With the continuous operation of the spraying system 3, after the spraying tank 01 for pre-heating furnace flue gas pre-dedusting is operated for a period of time, a part of upper clear water must be discharged to ensure that the water level is in a safe range. Therefore, a requirement is made for a speed of docking the drain pipe 21 with an external device or a pipeline, and further, as shown in fig. 1, the outlet end of the drain pipe 21 is provided with a quick coupling 211. The quick connector 211 can significantly shorten the butt joint time of the drain pipe 21 and external equipment or pipelines, thereby providing reliable guarantee for the long-time safe and stable operation of the flue gas pre-dedusting spray tank 01 for the preheating furnace.
Although the upper clarified water has a low dust content, the upper clarified water still has the possibility of polluting the environment, and further, as shown in fig. 1, a filter element 212 is detachably arranged in the drain pipe 21 in order to ensure the standard discharge of the upper clarified water; the filter element 212 and the drain valve 210 are arranged in sequence along the drain direction. The filter element 212 can filter fine particles in the upper clarified water, ensure the standard discharge of the upper clarified water and reduce the pollution risk to the environment. By placing the filter element 212 upstream of the water inlet end of the drain valve 210, the risk of fine particles clogging the drain valve 210 may be reduced.
Further, as shown in fig. 1, the drain pipe 21 is provided in detachable communication with the water storage device 32. When clear water and solid-state dust material sediment above needing to be discharged are discharged, the lower tank body 2 is set to be in a static state, then the drain pipe 21 is communicated with the water storage device 32, the drain valve 210 is set to be in an opening state, the water outlet of the drain pipe 21 is discharged into the water storage device 32, the water outlet of the drain pipe 21 is recycled, the water consumption of the flue gas pre-dedusting spray tank 01 for the preheating furnace can be greatly saved, and the production requirements of energy conservation and environmental protection are met.
When the lower tank body 2 is set to be in a rotating state, the connecting pipeline between the water discharging pipe 21 and the water storage device 32 can be disconnected, and meanwhile, the water discharging valve 210 is set to be in a closed state, so that the safe and stable operation of the flue gas pre-dedusting spraying tank 01 for the preheating furnace can be guaranteed.
In order to facilitate operators to know the solid-liquid separation degree in the lower tank body 2 in real time, a transparent observation window is further arranged on the lower tank body 2; the length direction of the transparent observation window is arranged along the direction of the conical generatrix of the lower tank body 2. Preferably, the height of the transparent observation window covers at least the range from the drain pipe 21 to the conical tip of the lower tank 2. The sedimentation condition at the small-opening end of the lower tank body 2 and the water quality condition at the drain pipe 21 can be clearly observed through the transparent observation window, so that an operator can conveniently judge the solid-liquid separation degree in the lower tank body 2 in real time.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structural changes made by the contents of the specification and the drawings, or the direct or indirect application in other related technical fields, are included in the same way in the protection scope of the present invention.
