[0025] Embodiment:
[0026] Reference Figure 1 - Figure 5 The utility model discloses a kind of slag flushing water smoke vapor collection equipment, including tower body 1, tower body 1 is equipped with spray cavity 4, the top of spray cavity 4 is fixedly connected with tail gas pipe 5, the bottom of the outer wall of spray cavity 4 is fixedly connected with gas supply pipe 6;
[0027] Spray component 2, it is set in the bottom of spray cavity 4, spray component 2 includes water tank 21, water supply pipe 22 and rotating spray head 23, water tank 21 is fixedly connected with the bottom wall of spray cavity 4, the top of water tank 21 is vertically connected with water supply pipe 22, the top of water supply pipe 22 is rotatably connected with rotating spray head 23;
[0028] Exhaust hood 3, it is set in spray cavity 4, exhaust hood 3 is generally annular, the surface of exhaust hood 3 is evenly distributed with mesh for air flow, the top and bottom of exhaust hood 3 are connected with the bottom of rotating spray head 23 and the top of water tank 21 respectively.
[0029] In the embodiment, observe Figure 1 And Figure 2 It can be found that by being equipped with spray cavity 4 in tower body 1, the top of spray cavity 4 is fixedly connected with tail gas pipe 5, the bottom of the outer wall of spray cavity 4 is fixedly connected with gas supply pipe 6, can be inhaled by fan Smoke vapor, then by gas supply pipe 6 at the bottom of tower body 1 input spray cavity 4, again by tail gas pipe 5 discharge.
[0030] And in Figure 2As can be seen, the bottom of the spraying cavity 4 is provided with a spraying assembly 2, the spraying assembly 2 comprises a water tank 21, a water supply pipe 22 and a rotating spray head 23, the water tank 21 is fixedly connected with the bottom wall of the spraying cavity 4, the top of the water tank 21 is vertically connected with the water supply pipe 22, the top end of the water supply pipe 22 is rotatably connected with the rotating spray head 23, water can be provided by the water tank 21, the water pump arranged in the water tank 21 is used to deliver water from the water supply pipe 22 to the rotating spray head 23, so that the rotating spray head 23 sprays a water curtain to purify the smoke, so as to achieve the purification effect of the water smoke of the slag. At the same time, the water curtain is sprayed out, which can reduce the temperature of the smoke, so as to condense the water in the smoke and reduce the waste of water resources.
[0031] And because the wet treatment needs the smoke to have enough contact time with water to ensure the purification efficiency, which leads to the need to control the flow rate of the smoke when collecting and processing the smoke, so that the purification efficiency of the smoke is slow, and therefore Figure 2 and Figure 3 It can be found that the exhaust hood 3 is arranged in the spraying cavity 4, the exhaust hood 3 is generally annular, the surface of the exhaust hood 3 is uniformly distributed with mesh holes for air flow, the top and bottom of the exhaust hood 3 are connected with the bottom of the rotating spray head 23 and the top of the water tank 21 respectively, and the smoke can be discharged through the mesh holes on the periphery of the exhaust hood 3 after entering the exhaust hood 3. At this time, when the exhaust amount is large, a large amount of smoke will accumulate in the exhaust hood 3, thereby increasing the air pressure in the exhaust hood 3, increasing the flow rate of the gas discharged through the mesh holes, and thereby making the gas impact on the inner wall of the spraying cavity 4, thereby greatly reducing the speed of the smoke, increasing the contact time of the smoke with the water curtain, and ensuring the purification effect of the smoke while ensuring the exhaust efficiency of the smoke.
[0032] In a further preferred embodiment of the present application, as shown in Figure 2 The inner wall of the spraying cavity 4 is connected with at least two water collecting rings 7 from top to bottom, and the bottom of the water collecting ring 7 is provided with water leakage holes 8.
[0033] The top of the water collecting ring 7 located at the top is lower than the height of the rotating spray head 23, and the water leakage holes 8 of the adjacent two water collecting rings 7 are staggered.
[0034] In this embodiment, it can be found that Figure 2 By arranging at least two water collecting rings 7 on the inner wall of the spraying cavity 4 from top to bottom, and arranging water leakage holes 8 in the bottom of the water collecting ring 7 in an annular array, the water sprayed by the rotating spray head 23 on the inner wall of the spraying cavity 4 can be collected and then uniformly leaked out through the water leakage holes 8, so that a water flow is formed on the inner wall of the spraying cavity 4, the gas sprayed by the exhaust hood 3 can be contacted with the water flowing on the inner wall of the spraying cavity 4, so as to play a role in preliminary purification, and then the gas flows upward to be contacted with the water curtain again for secondary purification, thereby further improving the purification effect.
[0035] In order to ensure the water collecting effect of the water collecting ring 7, the water collecting ring 7 is arranged as shown in the positional relationship. Figure 2 As shown in the positional relationship, the top of the water collecting ring 7 at the top is lower than the height of the rotating nozzle 23.
[0036] In order to ensure that the water flow can cover the inner wall of the spraying cavity 4 as much as possible, the water leakage holes 8 of adjacent two water collecting rings 7 are staggered, which can effectively improve the coverage area of the water flow.
[0037] In a further preferred embodiment of the utility model, as shown in Figure 4 and Figure 5 The rotating nozzle 23 comprises a rotating disc 231, a connecting sleeve 232 and an atomizing nozzle 233, the bottom of the rotating disc 231 is provided with an annular groove 9, the inner wall of the annular groove 9 is provided with a plurality of drainage grooves 10 in an annular array, the drainage grooves 10 are fixedly connected with the atomizing nozzle 233 at the side away from the annular groove 9, the bottom of the rotating disc 231 is rotatably connected with the connecting sleeve 232 at the outside of the annular groove 9, and the bottom of the connecting sleeve 232 is fixedly connected with the water supply pipe 22.
[0038] The connecting sleeve 232 is provided with an impeller 11, and the top of the impeller 11 is fixedly connected with the rotating disc 231 through a connecting shaft.
[0039] In this embodiment, the rotating nozzle 23 comprises the rotating disc 231, the connecting sleeve 232 and the atomizing nozzle 233, the bottom of the rotating disc 231 is provided with the annular groove 9, the inner wall of the annular groove 9 is provided with the plurality of drainage grooves 10 in an annular array, the drainage grooves 10 are fixedly connected with the atomizing nozzle 233 at the side away from the annular groove 9, the bottom of the rotating disc 231 is rotatably connected with the connecting sleeve 232 at the outside of the annular groove 9, and the bottom of the connecting sleeve 232 is fixedly connected with the water supply pipe 22.
[0040] At this time, the water pump runs to supply water into the connecting sleeve 232, into the annular groove 9 from the connecting sleeve 232, and finally into the atomizing nozzle 233 through the drainage groove 10, and a large amount of water mist is sprayed from the fine nozzles of the atomizing nozzle 233 to form a water curtain for purifying the smoke, thereby improving the purification effect on the smoke.
[0041] Since the coverage area of the atomizing nozzle 233 is limited, the water curtain at the joint position of adjacent two atomizing nozzles 233 is weak, which can cause the smoke purification effect at the position to be poor. Figure 5 It can be found that when the drainage groove 10 and the annular groove 9 are provided with an inclination angle, when the water flow in the atomizing nozzle 233 is sprayed, the sprayed water flow can exert a counter thrust on the rotating disc 231, and the multiple counter thrusts can collectively push the rotating disc 231 to rotate, thereby rotating the water curtain and improving the purification effect on the smoke as much as possible.

[0044] In the embodiment, the slag washing water contains gas, water vapor and impurities such as sulfide particles, so the sewage for purifying the flue gas contains particle impurities, and therefore it is observed that Figure 2 It can be found that the filter plate 12 is fixedly connected to the bottom of the spraying cavity 4, and the filter plate 12 is provided with a mounting groove 13 for avoiding the water tank 21, so that the sewage can be simply filtered by the filter plate 12, and the impurities can be filtered out from the sewage, thereby reducing the difficulty of subsequent sewage treatment.
[0045] The implementation principle of the above embodiment is that the flue gas is sent into the tower body 1 through the air supply pipe 6 by the high-power fan, and then the flue gas is sprayed out at the mesh of the exhaust cover 3, so that the flue gas contacts the inner wall of the spraying cavity 4 in the tower body 1, the exhaust speed of the flue gas is slowed down, the time of the flue gas staying in the spraying cavity 4 is increased, and the contact time of the flue gas with the water curtain is longer, so as to improve the purification effect of the flue gas.
[0046] The embodiments of the present application are preferable embodiments of the present application, and are not limited to the protection scope of the present application, so that: any equivalent changes made according to the structure, shape and principle of the present application should be covered in the protection scope of the present application.
