Description

Technical Field

[0001] The present invention relates to the technical field of tail gas treatment, and in particular to a hazardous waste tail gas system treatment device. Background Art

[0002] With the development of industry, the amount of hazardous waste discharged in the industrial production process is increasing. A large amount of hazardous waste is easy to volatilize harmful substances in storage warehouses, such as formaldehyde, VOC (toxic volatile gas), heavy metals (mercury, chromium, lead, etc.), Class I compounds, organic gases, etc., which will form harmful gases when combined with air. They are easy to accumulate and difficult to handle, and can easily spread with the air to cause environmental pollution.

[0003] When treating hazardous waste tail gas, the tail gas needs to be filtered before reacting with liquid alkali, but the filtered impurities are not easy to discharge, and it takes a lot of time to remove them, which reduces work efficiency and is inconvenient to use. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art that when treating hazardous waste exhaust gas, the exhaust gas needs to be filtered before reacting with liquid alkali, but the filtered impurities are not easy to discharge, and it takes a lot of time to remove them, which reduces work efficiency and is inconvenient to use. A hazardous waste exhaust gas system treatment device is proposed to solve the problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A hazardous waste tail gas system treatment device, comprising a treatment box, the top of the treatment box is fixedly connected to an arc-shaped cover, the top of the arc-shaped cover is fixedly connected to an exhaust pipe, an air inlet hole is opened on one side of the treatment box, one end of the air inlet hole is fixedly connected to the air inlet pipe, a fixing ring is fixedly connected to the inside of the treatment box, the bottom of the fixing ring is fixedly connected to an annular plate, and the outer wall of the annular plate is provided with a filter assembly for filtering tail gas;

[0007] A liquid inlet pipe is fixedly passed through one side of the arc-shaped cover, one end of the liquid inlet pipe extends to the interior of the treatment box, and one end of the liquid inlet pipe is provided with a treatment component for treating tail gas;

[0008] The outer wall of the treatment box is provided with a waste liquid barrel, and the interior of the waste liquid barrel is provided with a collecting component for collecting liquid alkali.

[0009] In one possible design, the filter assembly includes a filter plate slidably connected to the outer wall of the annular plate, the top of the filter plate is inclined, a plurality of filter holes are provided inside the filter plate, a baffle is fixedly connected to the bottom of the filter plate, and two symmetrically arranged discharge ports are provided on the outer wall of the processing box, and the baffle is used to block the discharge ports.

[0010] In one possible design, the processing component includes a connecting pipe fixedly connected to one end of the liquid inlet pipe, the bottom of the connecting pipe is fixedly connected to a hollow box, the bottom of the hollow box is fixedly connected to a plurality of nozzles, and the nozzles are located directly above the annular plate.

[0011] In a possible design, a fixing plate is fixedly connected to the top of the fixing ring. The fixing plate is located directly below the hollow box, and a groove is formed on the top of the fixing plate.

[0012] In a possible design, the collecting assembly includes a liquid outlet pipe fixedly connected to one side of the waste liquid barrel, a valve is provided on the liquid outlet pipe, and an overflow hole is opened on one side of the processing box, and the overflow hole is connected to the waste liquid barrel.

[0013] In a possible design, a collecting box is placed on the top of the waste liquid barrel, and an arc block is fixedly connected to one side of the collecting box. Two symmetrically arranged first plug holes are opened inside the arc block, and two symmetrically arranged arc grooves are opened on one side of the processing box, and the arc grooves are snap-connected with the arc block.

[0014] In a possible design, the outer wall of the filter plate is fixedly connected with two symmetrically arranged arc-shaped connecting plates, the bottom of the arc-shaped connecting plate is fixedly connected with two symmetrically arranged plug rods, the bottom inner wall of the discharge port is provided with two symmetrically arranged second plug holes, the bottom inner wall of the arc-shaped groove is provided with two symmetrically arranged slots, and the slots, the second plug holes and the first plug holes are all engaged with the plug rods.

[0015] In a possible design, an electric push rod is fixedly connected to one side of the bottom of the fixing ring, and a piston rod of the electric push rod is fixedly connected to one side of the top of the filter plate.

[0016] In the present application, when in use, the exhaust gas is sent into the interior of the treatment box through the intake pipe. At this time, impurities in the exhaust gas can be filtered through the filter holes. Due to the obstruction of the fixed ring and the annular plate, the exhaust gas cannot be discharged directly from the exhaust pipe. It needs to move down into the reserved liquid alkali first, and then be discharged through the interior of the annular plate, and finally discharged through the exhaust pipe;

[0017] During the exhaust gas discharge process, the liquid alkali can be sent into the interior of the connecting pipe through the liquid inlet pipe, and after entering the interior of the hollow box, it is finally discharged through multiple nozzles, which can fully react with the exhaust gas, and the fixed plate can collect the liquid alkali, and finally stay in the lower half of the treatment box, and the part exceeding the height of the overflow hole will be discharged into the interior of the waste liquid barrel for collection, and the valve can be opened to discharge through the liquid outlet pipe;

[0018] When it is necessary to discharge the waste, the electric push rod can be started, and the piston rod of the electric push rod drives the filter plate to move down, and the filter plate drives the baffle plate to move down. At this time, the baffle plate no longer blocks the discharge port, and the impurities remaining on the surface of the filter plate will be discharged through the discharge port and enter the collection box for collection. The surface of the filter plate is inclined, which can facilitate the discharge of impurities.

[0019] When the filter plate moves downward, it will drive the two arc-shaped connecting plates to move downward, and the arc-shaped connecting plates will drive the plug rod to move downward. The plug rod enters the interior of the arc-shaped groove through the second plug hole, and passes through the first plug hole to be connected to the interior of the slot. At this time, the stability of the collection box can be guaranteed to prevent the collection box from tipping over when the waste is dumped. When the filter plate is reset, the collection box is released from the brake and can be taken out normally.

[0020] Beneficial effects:

[0021] In the present invention, the hazardous waste tail gas system treatment device can achieve the effect of filtering tail gas through the filter component, which can not only filter the internal impurities, but also help to quickly discharge the filtered impurities, thereby reducing the workload;

[0022] In the present invention, the hazardous waste tail gas system treatment device can achieve the effect of treating tail gas through the treatment component, and can increase the mixing time of liquid alkali and tail gas, thereby improving the reaction effect;

[0023] In the present invention, the tail gas is sent into the interior of the treatment box through the air inlet pipe. At this time, impurities in the tail gas can be filtered through the filter holes, and the liquid alkali is sent into the interior of the connecting pipe through the liquid inlet pipe, and finally discharged through multiple nozzles, which can fully react with the tail gas. The filter plate drives the baffle to move downward, and the impurities remaining on the surface of the filter plate will be discharged through the discharge port and enter the interior of the collection box to complete the collection.
