Description

Technical Field

[0001] The utility model relates to the technical field of spray washing tower equipment, in particular to an exhaust gas spray washing tower with an intelligent spray system. Background Art

[0002] An exhaust gas spray washing tower is an environmental protection device used to treat dust, acidic gases, alkaline gases and other harmful gases in industrial waste gas. When the waste gas passes through the spray washing tower, the waste gas contacts the washing liquid medicine sprayed in the tower, and the pollutants in the waste gas are removed through physical adsorption and chemical reactions.

[0003] Multiple spray heads and packing layers are arranged inside the exhaust gas spray washing tower. The water pump of the water tank at the lower part of the exhaust gas spray washing tower is connected to supply liquid to the multiple spray heads. The multiple spray heads are spaced apart at different heights of the exhaust gas spray washing tower. The height difference between the spray heads will cause a difference in the supply liquid pressure of the spray. The higher the height of the spray head, the smaller the pressure. Increasing the water pressure of the higher spray head will cause the pressure of the lower spray head to be too high. It is difficult to precisely control the pressure of the spray heads at different height positions, which is not conducive to the precise utilization of the liquid medicine of the spray heads. Summary of the Invention

[0004] An embodiment of the present disclosure relates to an exhaust gas spray washing tower with an intelligent spray system. The lower medicine tank supplies liquid to the first spray rack through a first pump and supplies liquid to the upper buffer water tank at the same time. A second pump supplies liquid to the second spray rack. The first spray rack and the second spray rack with a vertical drop are independently controlled for spray pressure, avoiding the problem that when one pump supplies liquid to the first spray rack and the second spray rack, the height difference between the first spray rack and the second spray rack causes a large difference in spray pressure, and it is difficult to control the first spray rack and the second spray rack more precisely.

[0005] In a first aspect of the present disclosure, an exhaust gas spray washing tower with an intelligent spray system is provided, which specifically includes: a spray washing main tower body, a lower medicine tank and an upper buffer water tank. The lower medicine tank is fixedly arranged on the outer side of the lower part of the spray washing main tower body, the upper buffer water tank is fixedly arranged on the outer side of the middle part of the spray washing main tower body. A lower air inlet is communicated and arranged at the lower part of the spray washing main tower body. Transparent inspection and maintenance openings are arranged in an array in the vertical direction on the side surface of the spray washing main tower body. A packing layer is arranged inside the spray washing main tower body, and a mixing fan blade is rotated in cooperation with the central rotating shaft of the packing layer. An upper air outlet is communicated and arranged at the top of the spray washing main tower body.

[0006] In at least some embodiments, a first pump is fixedly connected and communicated at the upper part of the lower medicine tank, and the liquid outlet of the first pump is connected to the first spray rack through a pipeline.

[0007] In at least some embodiments, the first spray rack is fixedly arranged inside the spray washing main tower body, and the lower medicine tank is communicated with the bottom of the spray washing main tower body.

[0008] In at least some embodiments, a second pump is fixedly connected to the upper part of the upper buffer water tank in a communicating manner. The liquid outlet of the second pump is connected to the second spray rack through a pipeline, and the second pump supplies liquid for spraying to the second spray rack.

[0009] In at least some embodiments, the second spray rack is fixedly arranged inside the main spray washing tower body, and packing layers and mixing fan blades are arranged above and below the second spray rack.

[0010] In at least some embodiments, the liquid outlet of the first pump is connected to the upper buffer water tank through a pipeline. The first pump simultaneously injects the liquid medicine into the upper buffer water tank. The upper buffer water tank is located above the lower medicine tank. The first spray rack and the second spray rack with a vertical drop are independently controlled for the spray pressure by the first pump and the second pump.

[0011] In at least some embodiments, the first spray rack is located above the lower air inlet. The waste gas enters the main spray washing tower body through the lower air inlet and is then sprayed with the liquid medicine by the upper first spray rack. A packing layer and a mixing fan blade are arranged below the upper air outlet.

[0012] The present utility model provides an exhaust gas spray washing tower with an intelligent spray system, which has the following beneficial effects:

[0013] The lower medicine tank includes supplying liquid to the first spray rack through the first pump and simultaneously supplying liquid to the upper buffer water tank. The second pump supplies liquid to the second spray rack. The first spray rack and the second spray rack with a vertical drop are independently controlled for the spray pressure, avoiding the large spray pressure difference caused by the height difference between the first spray rack and the second spray rack when a single pump supplies liquid to the first spray rack and the second spray rack, and it is difficult to control the first spray rack and the second spray rack more precisely.

[0014] While the waste gas flows upward, it drives the mixing fan blade to rotate. The mixing fan blade promotes the circumferential flow mixing of the waste gas and the sprayed liquid medicine, and promotes the mixing effect of the waste gas and the liquid medicine.

All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1: Please refer to Figures 1 to 6 :

[0030] The utility model provides an exhaust gas spray washing tower with an intelligent spray system, comprising: a main spray washing tower body 1, a lower chemical agent tank 2 and an upper buffer water tank 3. A lower air inlet 101 is communicated and arranged at the lower part of the main spray washing tower body 1. Transparent inspection and maintenance openings 102 are arrayed in the vertical direction on the side surface of the main spray washing tower body 1. A packing layer 103 is arranged inside the main spray washing tower body 1. A mixing fan blade 104 is rotatably matched with the central rotating shaft of the packing layer 103. An upper air outlet 105 is communicated and arranged at the top of the main spray washing tower body 1. The lower part of the outer side of the main spray washing tower body 1 is fixedly provided with a lower chemical agent tank 2. A first pump 201 is fixedly communicated with the upper part of the lower chemical agent tank 2. The liquid outlet of the first pump 201 is communicated with a first spray rack 202 through a pipeline. The first spray rack 202 is fixedly arranged inside the main spray washing tower body 1. The lower chemical agent tank 2 is communicated with the bottom of the main spray washing tower body 1. The first spray rack 202 is located above the lower air inlet 101. The exhaust gas enters the main spray washing tower body 1 through the lower air inlet 101 and is then sprayed with liquid medicine by the upper first spray rack 202. The packing layer 103 and the mixing fan blade 104 are arranged below the upper air outlet 105. The middle part of the outer side of the main spray washing tower body 1 is fixedly provided with an upper buffer water tank 3. A second pump 301 is fixedly communicated with the upper part of the upper buffer water tank 3. The liquid outlet of the second pump 301 is communicated with a second spray rack 302 through a pipeline. The second pump 301 supplies liquid for the second spray rack 302 for spraying.

[0031] In the embodiment of the present disclosure, the second spray rack 302 is fixedly arranged inside the main spray washing tower body 1. The packing layer 103 and the mixing fan blade 104 are arranged above and below the second spray rack 302. The rotation of the mixing fan blade 104 promotes the circumferential flow and mixing of the exhaust gas and the sprayed liquid medicine, accelerates the mixing speed of the exhaust gas and the sprayed liquid medicine, and promotes the mixing effect of the exhaust gas and the liquid medicine.

[0032] In the embodiment of the present disclosure, the liquid outlet of the first pump 201 is communicated with the upper buffer water tank 3 through a pipeline. The first pump 201 simultaneously fills the liquid medicine into the upper buffer water tank 3. The upper buffer water tank 3 is located above the lower chemical agent tank 2. The first spray rack 202 and the second spray rack 302 with a vertical drop are independently controlled by the first pump 201 and the second pump 301 for the spray pressure. The first spray rack 202 and the second spray rack 302 can maintain the same pressure or different pressure differences. The spray pressures of the first spray rack 202 and the second spray rack 302 are intelligently adjusted, so that the liquid medicine is utilized more precisely, the usage amount of the liquid medicine is reduced, and the purification cost of the exhaust gas is reduced.

[0033] Embodiment 2: On the basis of Embodiment 1, the mixing fan blade 104 can be not arranged. The omission of the mixing fan blade 104 reduces the number of components, reduces the setting cost of the mixing fan blade 104, reduces the manufacturing and assembly difficulty, and achieves the purpose of cost reduction.

[0034] The working principle of this embodiment is as follows: the lower air inlet 101 is connected to the exhaust gas discharge pipe, the exhaust gas enters the spray washing main tower body 1 through the lower air inlet 101 and is then sprayed with liquid medicine by the upper first spray rack 202, the packing layer 103 is filled with adsorption balls, the liquid medicine continues to move upward through the packing layer 103 and is then sprayed with liquid medicine by the upper second spray rack 302, the liquid medicine continues to move upward through the packing layer 103 and is finally discharged from the upper air outlet 105, the lower medicine box 2 includes a first pump 201 to supply liquid to the first spray rack 202 for spraying, the first pump 201 simultaneously injects the liquid medicine into the upper buffer water tank 3, the second pump 301 supplies liquid to the second spray rack 302 for spraying, the first spray rack 202 and the second spray rack 302 with a vertical drop are independently controlled by the first pump 201 and the second pump 301 to control the spray pressure, the first spray rack 202 and the second spray rack 302 can maintain the same pressure or different pressure differences , the lower medicine box 2 and the first pump 201 and the first spray rack 202 and the second spray rack 302 and the upper buffer water tank 3 and the second pump 301 form an intelligent spray system, and the spray pressure of the first spray rack 202 and the second spray rack 302 is intelligently adjusted, so that the liquid medicine is used more accurately, the amount of liquid medicine used is reduced, and the purification cost of exhaust gas is reduced, which avoids the existing equipment that a pump supplies liquid to the first spray rack 202 and the second spray rack 302. The height difference between the first spray rack 202 and the second spray rack 302 leads to a large difference in spray pressure. The second spray rack 302 at a high place must be smaller than the first spray rack 202. It is difficult to control the first spray rack 202 and the second spray rack 302 more accurately. The second spray rack 302 and the packing layer 103 are arranged in multiple layers as needed, and each layer of the second spray rack 302 is provided with an upper buffer water tank 3 and a second pump 301, and the vertically adjacent upper buffer water tanks 3 and the second pump 301 are connected by pipelines;

[0035] While the exhaust gas flows upward, it drives the mixing blades 104 to rotate in a circular direction. The rotation of the mixing blades 104 promotes the circumferential flow mixing of the exhaust gas and the spray liquid, accelerates the mixing speed of the exhaust gas and the spray liquid, promotes the mixing effect of the exhaust gas and the liquid, and improves the purification efficiency of the exhaust gas.
