Description

Technical Field

[0001] This utility model relates to the technical field of environmental protection equipment, and in particular to a harmless waste gas spray purification device. Background Technology

[0002] Harmless waste gas refers to waste gas that, under specific conditions, does not pose a significant threat to human health and the environment. This does not mean that these waste gases are completely harmless, but rather that their degree of harm is lower compared to some toxic and harmful waste gases.

[0003] Existing harmless waste gas spray purification equipment, such as the waste gas treatment device disclosed in utility model patent application number 202421297307.8, mainly includes a main tank, a fixed plate connected to the upper part of the main tank, a water tank connected to the upper part of the fixed plate, a water outlet pipe connected to one side of the water tank, the water outlet pipe passing through the fixed plate and rotatably connected to a rotating rod, a treatment device connected inside the main tank, a motor fixedly connected to the upper end of the main tank, the motor output shaft fixedly connected to a first gear, the rotating rod passing through a second gear and fixedly connected to the second gear, and the first gear meshing with the second gear; in use: waste gas enters through the air inlet. Inside the main tank, the motor is started to drive the first gear to rotate. The first gear drives the second gear and the rotating rod to rotate. Water is discharged from the water tank and flows through the water outlet to the rotating rod and the crossbar. At this time, the spray head sprays water mist, so that the exhaust gas in the main tank comes into contact with the water mist. When the rotating rod drives the crossbar to rotate, the water mist is evenly distributed in the main tank to adhere to the exhaust gas. At this time, the water mist with impurities falls to the bottom of the main tank and flows to the fixed shell through the liquid outlet. The air passes through the filter screen to further filter impurities. The filter screen can be pulled out of the fixed slot for replacement. When the wastewater flows to the activated carbon filter plate, the impurities are adsorbed, and the water flows to the bottom of the fixed shell and is discharged through the outlet.

[0004] However, the exhaust gas is generally still at a high temperature. Most existing purification equipment directly sprays water to cool it down, but the heat in the exhaust gas is not effectively recovered and utilized. Moreover, the dust reduction effect of a single spray is poor, and multiple sprays result in a large waste of water resources. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a harmless waste gas spray purification device that can not only absorb and reuse the heat in the waste gas, thus improving energy utilization, but also perform dual dust reduction on the waste gas without increasing water consumption, thereby enhancing the treatment effect.

[0006] This utility model discloses a harmless waste gas spray purification device, including a spraying mechanism; it also includes a stirring mechanism, a connecting mechanism, a heat exchange mechanism, and a rinsing mechanism. The stirring mechanism is installed on the spraying mechanism and drives the waste gas flow; the connecting mechanism is installed on the spraying mechanism and pre-treats the waste gas; the heat exchange mechanism is installed on the connecting mechanism and recovers residual heat from the waste gas; and the rinsing mechanism is installed on the heat exchange mechanism and rinses the heat exchange mechanism. The harmless waste gas is transported to the connecting mechanism, where clean water absorbs the heat from the waste gas for subsequent use. Simultaneously, the stirring mechanism blocks dust in the waste gas, accelerating dust settling. The connecting mechanism transports the waste gas to the spraying mechanism, where the stirring mechanism drives the waste gas flow, extending the residence time of the waste gas in the spraying mechanism. The spraying mechanism sprays clean water to further cool and remove dust from the waste gas. After prolonged use, the heat exchange mechanism transports clean water to the rinsing mechanism, which rinses the heat exchange mechanism to prevent dust from adhering to it and affecting the heat exchange effect.

[0007] Preferably, the spraying mechanism includes a support frame, a water tower, a filter plate, a chimney, a water distribution tray, and multiple sets of spray heads. The bottom end of the support frame is connected to the ground, and the bottom end of the water tower is connected to the top end of the support frame. The water tower has an internal cavity and a drain outlet at its bottom end. The filter plate is installed inside the cavity of the water tower. The bottom end of the chimney is connected to the top end of the water tower. The water distribution tray is installed inside the cavity of the water tower, and multiple sets of spray heads are installed on the water distribution tray. The exhaust gas is transported to the cavity of the water tower through a connecting mechanism. The heat exchange mechanism transports clean water to the water distribution tray, which distributes the clean water to the multiple sets of spray heads. The spray heads spray the clean water to purify and remove dust from the exhaust gas. At the same time, the filter plate filters the exhaust gas to enhance the purification effect. The purified exhaust gas is discharged through the chimney.

[0008] Preferably, the stirring mechanism includes a motor, a reducer, a drive shaft, three sets of fan blades, and a scraper. The motor and the reducer are mounted on the water tower. The drive shaft is rotatably mounted inside the cavity of the water tower and longitudinally connected to the reducer. All three sets of fan blades are mounted on the drive shaft, and the scraper is mounted on the drive shaft. When the motor is started, it drives the drive shaft to rotate through the reducer. The drive shaft drives the three sets of fan blades to rotate, which accelerates the airflow and prolongs the time the airflow stays in the cavity of the water tower, thus extending the purification time of the exhaust gas. At the same time, the drive shaft drives the scraper to rotate, and the scraper scrapes the bottom of the cavity of the water tower, accelerating the discharge of wastewater through the drain outlet of the water tower.

[0009] Preferably, the connecting mechanism includes a treatment box, a connecting pipe, a gas supply pipe, a check valve, a drain pipe, and a drain valve. The bottom end of the treatment box is connected to the top end of the support frame. The treatment box has an internal cavity. The connecting pipe is installed on the treatment box and communicates with the internal cavity of the treatment box. The gas supply pipe is connected between the treatment box and the water tower. The check valve is installed on the gas supply pipe. The drain pipe is connected between the treatment box and the water tower. The drain valve is installed on the drain pipe. The connecting pipe is connected to the exhaust end of the equipment. Harmless waste gas enters the internal cavity of the treatment box through the connecting pipe. Heat exchange occurs with the heat exchange mechanism in the internal cavity of the treatment box, and some dust settles. Then, the gas is transported to the cavity of the water tower through the gas supply pipe. The check valve prevents backflow of air. After the flushing mechanism has finished flushing the heat exchange mechanism, the drain valve is opened, and the wastewater is transported to the cavity of the water tower through the drain pipe and discharged centrally.

[0010] Preferably, the heat exchange mechanism includes a water pump, a pumping pipe, a first water supply pipe, a second water supply pipe, a first valve, and two sets of heat exchange boxes. The bottom of the water pump is connected to the top of the treatment tank. The pumping pipe is installed on the water pump. The first water supply pipe is installed on the water pump and communicates with the inside of the water distribution pan. The second water supply pipe is installed on the first water supply pipe and communicates with the inside of the first water supply pipe. The first valve is installed on the second water supply pipe. Both sets of heat exchange boxes are installed inside the treatment tank and communicate with the inside of the first valve. When the water pump is started, the pumping pipe is connected to the water source. The water pump pumps clean water and delivers it to the water distribution pan through the first water supply pipe. The first valve is opened, and the first water supply pipe delivers clean water to the two sets of heat exchange boxes through the second water supply pipe. The clean water exchanges heat with the harmless waste gas through the heat exchange boxes, absorbing the heat in the waste gas for subsequent use. At the same time, the two sets of heat exchange boxes are tilted to block the waste gas and accelerate the settling of dust in the waste gas.

[0011] Preferably, the rinsing mechanism includes a third water supply pipe, a second valve, a water distributor, and multiple sets of nozzles. The third water supply pipe is internally connected to the first water supply pipe. The second valve is installed on the third water supply pipe. The water distributor is installed on the treatment box and is internally connected to the second valve. The multiple sets of nozzles are all installed inside the treatment box and are internally connected to the water distributor. After long-term use, the second valve is opened, and the first water supply pipe delivers clean water to the water distributor through the third water supply pipe. The water distributor distributes the clean water to the multiple sets of nozzles, which rinse the outer surfaces of the two heat exchange boxes, washing away the dust adhering to the surface of the heat exchange boxes and ensuring the heat exchange effect of the heat exchange boxes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: harmless waste gas is transported to the connecting mechanism, and the clean water in the heat exchange mechanism absorbs the heat in the waste gas, which is convenient for subsequent use. At the same time, the stirring mechanism blocks the dust in the waste gas and accelerates the dust settling in the waste gas. The connecting mechanism transports the waste gas to the spraying mechanism, and the stirring mechanism drives the waste gas to flow, prolonging the residence time of the waste gas in the spraying mechanism. The spraying mechanism sprays clean water to further cool and remove dust from the waste gas. After long-term use, the heat exchange mechanism transports clean water to the rinsing mechanism, and the rinsing mechanism rinses the heat exchange mechanism to prevent dust from adhering to the heat exchange mechanism and affecting the heat exchange effect.
