[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a steel structure anti-corrosion spraying waste gas circulation purification device.

[0026] The utility model provides Figure 1-3 The steel structure anti-corrosion spraying waste gas circulation purification device shown in the figure comprises a water curtain cabinet 1 and an exhaust fan 2 connected to the top of the water curtain cabinet 1. A plurality of water curtain baffles 3 are arranged inside the water curtain cabinet 1. A circulating water pool 4 is fixedly arranged at the lower end of the interior of the water curtain cabinet 1. A circulating water pump 5 is fixedly arranged on the top of the circulating water pool 4. The two ends of the circulating water pump 5 are respectively connected with an inlet pipe 6 and an outlet pipe 7. The pipe mouth fixed sleeve of the inlet pipe 6 is provided with an anti-blocking net 20. The upper end of the outlet pipe 7 passes through the water curtain cabinet 1. The air outlet fixed sleeve of the exhaust fan 2 is provided with a fuel A burning tube 8, the inner wall of which is fixedly provided with a plurality of electric heating wires 9, a supporting ring 10 is fixedly provided on the outer wall of the burning tube 8, a filter screen 11 is provided inside the supporting ring 10, a material box 12 is fixedly provided on the outer wall of the circulating water pool 4, a partition 15 is fixedly provided on the inner wall of the material box 12, a paint mist coagulant 16 and a paint mist flocculant 17 are provided on both sides of the partition 15 and in the material box 12, respectively, a motor 21 is fixedly provided at the bottom of the circulating water pool 4, an output end of the motor 21 penetrates into the circulating water pool 4 and is fixedly provided with a stirring fan blade 22.

[0027] Before purifying the spraying waste gas, the paint mist coagulant 16 and the paint mist flocculant 17 in the material box 12 are put into the circulating water pool 4, and the motor 21 is started, so that the stirring fan blades 22 can stir the water in the circulating water pool 4, so that the agent can be mixed with the water, and then the exhaust fan 2 is started, so that the spraying waste gas can enter the water curtain cabinet 1 and contact the water curtain on the water curtain baffle 3, so that part of the waste gas can be sprayed, and under the flushing of the water, the pollutants in the waste gas fall into the circulating water pool 4, and with the cooperation of multiple agents, the pollutants are removed. The flocculants are cleaned and floated, which is convenient for cleaning. At this time, under the setting of the anti-blocking net 20, the circulating water pump 5 can suck the purified water inside the circulating water pool 4, and discharge it into the water curtain cabinet 1 for recycling again. The gas after spraying enters the combustion tube 8 through the exhaust fan 2 again. At this time, multiple heating wires 9 are started and the gas is burned at high temperature, so that the gas can be purified again. Subsequently, the gas is burned and discharged outwardly through the filter net 11, and the particulate matter inside the gas is finally filtered, so as to complete the complete purification of the spraying exhaust gas and improve the purification effect.

[0028] In order to ensure that the exhaust gas can be discharged into the air after combustion, Figure 1 As shown, a VOC sensor 13 is fixedly provided on the outer wall of the combustion tube 8 , and the detection end of the VOC sensor 13 extends into the interior of the combustion tube 8 . An alarm 14 is fixedly provided on the outer wall of the combustion tube 8 , and the alarm 14 is electrically connected to the VOC sensor 13 .

[0029] After the exhaust gas is burned, the VOC sensor 13 can be used to detect the pollutant content inside the exhaust gas after combustion, and the alarm 14 can be used to ensure that the exhaust gas is effectively burned and purified.

[0030] In order to obtain quick and convenient replacement of the filter screen 11 after long-term use, Figure 2 As shown, limit rods 18 are slidably penetrated on both sides of the support ring 10, and the limit rods 18 are arranged on the outside of the filter screen 11. A spring 19 is sleeved on the rod wall of the limit rod 18. The two ends of the spring 19 are respectively fixedly connected to the limit rod 18 and the support ring 10, and a pulling hole is opened at the end of the limit rod 18.

[0031] After the filter 11 has been filtering exhaust gas for a long time, the limit rods 18 on both sides can be pulled at the same time, so that the two limit rods 18 move away from each other and are pulled out of the support ring 10. At this time, the spring 19 is stretched, and the filter 11 can be directly taken out, and the new filter can be reinstalled in the support ring 10, and the limit rod 18 is loosened. Under the elastic force of the spring 19, the limit rod 18 rebounds to its original position and continues to limit and block the filter 11, thereby determining the use position of the filter 11.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
