A spray cleaning device for smelting flue gas

Abstract

This utility model discloses a spray purification device for smelting flue gas, relating to the field of flue gas purification technology. It includes a housing, with a transmission mechanism on the top of the housing. The transmission mechanism includes a column fixedly connected to the rear side of the top of the housing, and a driven wheel rotatably connected to the column. A reciprocating mechanism is also provided on the top of the housing, with the driven wheel driving the reciprocating mechanism. The reciprocating mechanism includes a rocker arm rotatably connected to one side of the driven wheel. The beneficial effect is that when the pusher plate moves forward in the bellows, a negative pressure is generated inside the bellows, forcing air upwards through the front air inlet. This process is repeated when the pusher plate moves backward in the bellows. The baffles converge the air, continuously injecting it into the water tank through the air guide pipe, increasing the pressure inside the water tank. This increased pressure also increases the pressure of the atomizing nozzles, increasing the spray area and thus achieving a better spray purification effect on the air.

Description

Technical Field

[0001] This utility model relates to the field of flue gas purification technology, and in particular to a spray purification device for smelting flue gas. Background Technology

[0002] In the process of gold smelting, special technologies and methods are generally used to extract gold from gold mines. Gold smelting often generates a large amount of waste gas, so flue gas treatment equipment is needed to treat the waste gas. The waste gas generated by gold smelting contains a lot of heat. When this hot waste gas is directly discharged, it will cause a warming effect on the environment. This kind of pollution that can cause adverse warming effects on the environment during energy consumption and conversion is called thermal pollution. Thermal pollution can cause abnormal climate, severe drought, and damage to the original ecological balance.

[0003] However, current flue gas spraying devices often require external devices to pressurize the nozzles in order to achieve a good flue gas purification effect, which is costly. Utility Model Content

[0004] The purpose of this invention is to provide a spray purification device for smelting flue gas in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions: A spray purification device for smelting flue gas includes a housing.

The reciprocating mechanism includes a rocker arm rotatably connected to one side of the driven wheel. A slider is rotatably connected to the rocker arm. A limit frame is slidably connected to the slider. A limit rod is fixedly connected to the rear side of the limit frame, and a limit bar is fixedly connected to the front side of the limit frame. The push rod has a push plate fixedly connected to its front side. A water storage mechanism and an air supply mechanism are installed on the top of the box.

A limit plate is fixedly connected to the rear top of the box. The rear side of the limit rod is slidably connected to the limit plate. An air inlet pipe is fixedly connected to the top of one side of the box. An exhaust pipe is fixedly connected to the side of the box away from the air inlet pipe. A water outlet pipe is fixedly connected to the bottom of the side of the box near the air inlet pipe.

[0006] Preferably, the transmission mechanism includes a motor, which is fixedly connected to the top front side of the housing. The output end of the motor is fixedly connected to a drive pulley, and a synchronous belt is connected to the drive pulley. The rear end of the synchronous belt is connected to the driven pulley.

[0011] The beneficial effects are as follows: when the pusher plate of the device moves forward in the bellows, a negative pressure is generated inside the bellows, which discharges air upward through the air inlet on the front side. When the pusher plate moves backward in the bellows, this process is repeated. The baffle gathers the air, causing the bellows to continuously inject air into the water tank through the air guide pipe, which increases the pressure inside the water tank.

[0017] The present invention will be further described below with reference to the accompanying drawings: like Figure 1-7As shown in the figure, a spray purification device for smelting flue gas includes a housing 1. A transmission mechanism is provided on the top of the housing 1. The transmission mechanism includes a column 205, which is fixedly connected to the rear side of the top of the housing 1. A driven wheel 204 is rotatably connected to the column 205. A reciprocating mechanism is provided on the top of the housing 1. The driven wheel 204 is used to drive the reciprocating mechanism to move. The reciprocating mechanism includes a rocker arm 301, which is rotatably connected to one side of the driven wheel 204. A slider 302 is rotatably connected to the rocker arm 301. A limit frame 303 is slidably connected to the slider 302. A limit rod 304 is fixedly connected to the rear side of the limit frame 303. A push rod 305 is fixedly connected to the front side of the limit frame 303. A push plate 306 is fixedly connected to the front side of the push rod 305. The rotation of the driven wheel 204 drives the rocker arm 301 to rotate, and the rotation of the rocker arm 301 drives... The slider 302 slides on the inner surface of the limiting frame 303, causing the limiting frame 303 to drive the limiting rod 304 to reciprocate in the horizontal direction under the limiting action of the limiting plate 8. A water storage mechanism is provided on the top of the box 1, and an air supply mechanism is provided on the top of the box 1. The reciprocating mechanism is used to drive the air supply mechanism to move. A spraying mechanism is provided on the box 1, and a drainage mechanism is provided inside the box 1. The limiting plate 8 is fixedly connected to the rear side of the top of the box 1, and the rear side of the limiting rod 304 is slidably connected to the limiting plate 8. An air inlet pipe 9 is fixedly connected to the top of one side of the box 1, and an exhaust pipe 10 is fixedly connected to the side of the box 1 away from the air inlet pipe 9. A water outlet pipe 11 is fixedly connected to the bottom of the side of the box 1 near the air inlet pipe 9. The operator can connect the air inlet pipe 9 to an external air supply device, and connect the exhaust pipe 10 and the water outlet pipe 11 to external air extraction and water extraction devices, respectively.

[0018] The transmission mechanism includes a motor 201, which is fixedly connected to the top front side of the housing 1. The output end of the motor 201 is fixedly connected to a drive wheel 202, and a synchronous belt 203 is connected to the drive wheel 202. The rear end of the synchronous belt 203 is connected to the driven wheel 204. The rotation of the motor 201 drives the drive wheel 202 to rotate, and drives the driven wheel 204 to rotate through the synchronous belt 203.

[0019] The water storage mechanism includes a water tank 401, which is fixedly connected to the top of the housing 1. A bellows 402 is fixedly connected to the side of the water tank 401 near the motor 201. Air holes are provided on both the front and rear sides of the bellows 402, and cover plates are hinged to the air holes. The cover plates are located inside the bellows 402. A drain pipe 403 is fixedly connected to the bottom of the side of the water tank 401 near the motor 201.

[0020] The air supply mechanism includes two baffles 501, which are fixedly connected to the top of the air box 402. The air box 402 has two air inlets 502. The top of the air box 402 is fixedly connected to an air guide pipe 503, and the other end of the air guide pipe 503 is fixedly connected to the top of the water tank 401. When the push plate 306 moves forward in the air box 402, a negative pressure is generated inside the air box 402, which discharges the air inside the air box 402 upward through the front air inlet 502. When the push plate 306 moves backward in the air box 402, this process is repeated. The air box 402 is continuously injected into the interior of the water tank 401 through the air guide pipe 503 by the baffles 501.

[0021] The spraying mechanism includes a driving bevel gear 601, which is fixedly connected to the output end of the motor 201. A driven bevel gear 602 meshes with the side of the driving bevel gear 601 near the water tank 401. The driven bevel gear 602 has a hollow structure, and several atomizing nozzles 603 are fixedly connected to the bottom of the driven bevel gear 602. The drain pipe 403 is rotatably connected to the inner surface of the driven bevel gear 602, and the bottom end of the drain pipe 403 is connected to the inside of the atomizing nozzles 603. When the motor 201 is started, the motor 201 drives the driving bevel gear 601 to rotate, which in turn drives the driven bevel gear 602 to rotate. The rotation of the driven bevel gear 602 drives the atomizing nozzles 603 at its bottom to rotate, thereby spraying the gas entering the chamber 1, adsorbing dust, and finally expelling the air inside the chamber 1 through the exhaust pipe 10.

[0022] The drainage mechanism includes a partition 701, which is fixedly connected to the inside of the box 1. The partition 701 has an arc-shaped structure and a drain outlet 702 is provided on the partition 701. A wastewater chamber 703 is provided inside the box 1.

[0023] Working principle: When using this device, the operator first connects the air inlet pipe 9 to the external air supply equipment, connects the exhaust pipe 10 and the water outlet pipe 11 to the external air extraction and water extraction equipment respectively, and fills the water tank 401 with a certain amount of water.

[0024] Start the motor 201, which drives the active bevel gear 601 to rotate, thereby driving the driven bevel gear 602 to rotate. The rotation of the driven bevel gear 602 will drive the atomizing nozzle 603 at its bottom to rotate, thereby spraying the gas entering the chamber 1, adsorbing dust, and finally expelling the air inside the chamber 1 through the exhaust pipe 10.

[0025] The motor 201 rotates to drive the drive wheel 202 to rotate, and drives the driven wheel 204 to rotate via the synchronous belt 203. The rotation of the driven wheel 204 drives the rocker arm 301 to rotate. The rotation of the rocker arm 301 drives the slider 302 to slide on the inner surface of the limiting frame 303, so that the limiting frame 303 drives the limiting rod 304 to reciprocate in the horizontal direction under the limiting action of the limiting plate 8. The reciprocating movement of the limiting frame 303 drives the push rod 305 to make the push plate 306 reciprocate within the bellows 402.

[0026] When the push plate 306 moves forward in the bellows 402, a negative pressure is generated inside the bellows 402. The front cover closes due to the negative pressure, and the rear cover opens due to the negative pressure. The push plate 306 discharges the air inside the bellows 402 upward through the front air inlet 502. When the push plate 306 moves backward in the bellows 402, this process is repeated. The baffle 501 gathers the air, causing the bellows 402 to continuously inject air into the water tank 401 through the air guide pipe 503.

[0027] The injected air will increase the pressure inside the water tank 401, which in turn will increase the pressure inside the atomizing nozzle 603, increasing the spray area and thus achieving a better spray purification effect on the air.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
