A waste gas spraying device for a 2-hydroxy-3-naphthoic acid production process comprises a spraying tower, a fan, a spraying liquid barrel, a plurality of filter screen plates, a plurality of guide plates, a water diversion pipe, a water pump and an air inlet pipe, wherein the spraying tower is arranged on a rack, an opening at the upper end of the spraying tower forms an air outlet, the air inlet pipe is connected with the side wall of the lower part of the spraying tower, and the bottom of the spraying tower is connected with a drain pipe lower than the air inlet pipe; the plurality of filter screen plates are obliquely arranged inside the spray tower respectively, and the filter screen plates are longitudinally distributed in the spray tower at intervals; each guide plate is respectively pasted on the inner wall of the spray tower and is lapped on the edges of two adjacent filter screen plates, the water distribution pipe is fixedly arranged on the inner wall of the upper part of the spray tower and is connected with the higher side edge of the uppermost filter screen plate, a plurality of water distribution holes are arranged on the side wall of the water distribution pipe, the end part of the water distribution pipe is connected with the spray liquid barrel through a water supply pipe, and the water pump is connected in the water supply pipe; the fan is connected to the inner side of the exhaust port.
The waste gas spraying device for the 2-hydroxy-3-naphthoic acid production process is further designed in such a way that the inclination directions of two adjacent filter screen plates are opposite, so that a guide plate between two adjacent filter screen plates is connected with the bottom side edge of the upper filter screen plate and the upper side edge of the lower filter screen plate.
The waste gas spraying device for the 2-hydroxy-3-naphthoic acid production process is further designed in that an alkali liquor is contained in the spraying liquid barrel.
The waste gas spraying device for the 2-hydroxy-3-naphthoic acid production process is further designed in that hot water is contained in the spraying liquid barrel.
The waste gas spraying device for the 2-hydroxy-3-naphthoic acid production process is further designed in that hot alkali liquor is contained in the spraying liquid barrel.
The beneficial effects of the utility model reside in that: through adopting filter plate, when the even flow of spray filters filter plate, the automatic water film that forms on the wire side, and then waste gas is when passing the water film under the negative pressure is drawn, and the water film bursts and is formed a large amount of water smoke to utilize water film and water smoke formation to spray twice of waste gas and dissolve the adsorption, have better treatment effect, and the spray need not high-pressure drive also need not to set up high-pressure shower head.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The invention is further described with reference to the drawings and examples in the following description:
The waste gas spraying device for the 2-hydroxy-3-naphthoic acid production process comprises a spraying tower 1, a fan 2, a spraying liquid barrel 3, a plurality of filter screen plates 4, a plurality of guide plates 5, a water distribution pipe 6, a water pump 7 and an air inlet pipe 8, wherein the spraying tower is arranged on a frame 9, an upper end opening of the spraying tower forms an air outlet 91, the air inlet pipe is connected with the lower side wall of the spraying tower, and the bottom of the spraying tower is connected with a drain pipe 10 lower than the air inlet pipe; the plurality of filter screen plates are obliquely arranged inside the spray tower respectively, and the filter screen plates are longitudinally distributed in the spray tower at intervals; each guide plate 5 is respectively pasted on the inner wall of the spray tower and is overlapped with the edges of two adjacent filter screen plates, the water distribution pipe is fixedly arranged on the inner wall of the upper part of the spray tower and is connected with the higher side edge of the uppermost filter screen plate, the side wall of the water distribution pipe is provided with a plurality of water distribution holes, the end part of the water distribution pipe is connected with the spray liquid barrel through a water supply pipe, and the water pump is connected in the water supply pipe; the fan 2 is connected to the inside of the exhaust port.
Through adopting filter plate, when the even flow of spray filters filter plate, the automatic water film that forms on the wire side, and then waste gas is when passing the water film under the negative pressure is drawn, and the water film bursts and is formed a large amount of water smoke to utilize water film and water smoke formation to spray twice of waste gas and dissolve the adsorption, have better treatment effect, and the spray need not high-pressure drive also need not to set up high-pressure shower head.
