Description

Technical Field

[0001] The utility model relates to the technical field of chemical waste gas absorption and treatment equipment, in particular to chemical waste gas absorption and treatment equipment. Background Art

[0002] The waste gas absorption treatment tank is a device that puts waste gas into the treatment tank to carry out a series of physical or chemical reactions to react harmful gases in the waste gas into harmless gases for discharge. When treating chemical waste gas, waste gas treatment tanks are often used for treatment. The waste gas is put into the treatment tank through the air inlet for reaction treatment to generate harmless gases for discharge.

[0003] The inventor discovered during daily use of the waste gas absorption treatment tank that since the waste gas reacts inside the purification tube that enters the treatment tank to generate harmless gas, long-term use of the purification tube will cause the raw materials inside the purification tube to undergo oxidation or reduction reactions with the waste gas, thereby causing the purification capacity of the purification tube to gradually weaken, and the purification tube needs to be replaced. Since the purification tube is arranged inside the treatment tank by means of screws and other parts, and since there are multiple purification tubes inside the treatment tank, it is inconvenient to replace the purification tube, which in turn causes an impact. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a chemical waste gas absorption and treatment device.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a chemical waste gas absorption and treatment equipment, including a treatment tank, a water inlet and a water outlet are fixedly connected to the side of the treatment tank, a fixed plate is fixedly connected to the inside of the treatment tank, a purification pipe is arranged on the upper top of the fixed plate, an upper and lower bottom of the treatment tank are respectively fixedly connected with an air inlet pipe and an exhaust pipe, a replacement device is arranged on the upper top of the fixed plate, a cleaning device is arranged inside the treatment tank, the replacement device includes a hollow rod fixedly connected to the top of the fixed plate, a purification pipe is inserted into the inside of the hollow rod, a groove is opened on the inner wall of the hollow rod, and a sealing ring is fixedly connected to the surface of the purification pipe.

[0006] The effects achieved by the above components are: under the action of the replacement device, the purification pipe can be replaced, avoiding the phenomenon that the purification pipe is used for too long and affects the purification of exhaust gas. When treating exhaust gas, the exhaust gas is discharged into the interior of the treatment tank through the air inlet pipe at the bottom of the treatment tank. Under the action of the fixed plate, the exhaust gas enters the interior of the purification pipe for purification. Cooling water flows into the interior of the treatment tank through the water inlet pipe to cool the exhaust gas. When the purified exhaust gas is discharged through the outlet, the treatment of chemical waste gas is completed.

[0007] Preferably, a groove is provided on the top of the purification tube, a spring is fixedly connected inside the groove, a bump is fixedly connected to one end of the spring, a round rod is fixedly connected to the bottom of the fixing plate, and the bump is inserted into the inside of the round rod.

[0008] The effect achieved by the above components is that under the action of the spring, the protrusion can be squeezed into the inside of the groove when installing the purification tube, thereby achieving the effect of facilitating the installation of the purification tube.

[0009] Preferably, a snap ring is fixedly connected to the surface of the protrusion, an annular groove is formed on the inner wall of the round rod, and the snap ring is interference fit with the annular groove.

Under the action of the sealing ring and the groove body, sealing is performed, and the protrusion is squeezed into the inside of the groove. When one end of the purification tube is in the same plane as the round rod, under the action of the spring, the protrusion is inserted into the inside of the round rod. Under the action of the clamping ring and the ring groove, no leakage occurs at the connection. The clamping rod is pressed down to fix the protrusion inside the round rod, thereby achieving the effect of replacing the purification tube.

[0013] Preferably, the cleaning device includes a motor fixedly connected to the top of the processing tank, the output end of the motor is fixedly connected to a rotating shaft, the surface of the rotating shaft is threaded, the surface of the rotating shaft is threadedly connected to a scraper, and the bottom of the scraper is fixedly connected to a scraper strip.

[0014] The effect achieved by the above components is that under the action of the scraper and the thread, the scraper can move up and down inside the treatment tank, thereby cleaning the scale on the inner wall of the treatment tank and achieving the cleaning effect.

[0015] Preferably, the scraper is slidably connected to the surface of the purification tube, and a triangular plate is fixedly connected to the bottom of the scraper, and the triangular plate is tightly attached to the surface of the purification tube.

[0016] The effect achieved by the above components is that under the action of the triangular plate, the scale on the surface of the purification pipe can be cleaned, thereby achieving the cleaning effect.

[0019] Preferably, a stopper is fixedly connected to the side surface of the arc-shaped plate, and both the arc-shaped plate and the stopper are made of corrosion-resistant plastic.

[0020] The effects achieved by the above components are as follows: under the action of the block, the oily substances that are scraped off will not block the pipe opening of the purification pipe, thereby avoiding the effect of blocking the purification pipe. When the inside of the treatment tank needs to be cleaned, the motor is started to rotate the shaft, thereby driving the scraper to move up and down. With the cooperation of the triangular plate, the scale on the inner wall of the treatment tank and the surface of the purification pipe can be cleaned. When the inner wall of the treatment tank is adhered to by the oily substances in the exhaust gas that are cooled and precipitated due to the cooling water, under the action of the arc plate and the block, the oily substances are blocked between the arc plate and the block, thereby not blocking the pipe opening of the purification pipe, thereby achieving the cleaning effect.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

Under the action of the sealing ring and the groove body, sealing is performed, and the protrusion is squeezed into the interior of the groove. When one end of the purification tube is in the same plane as the round rod, the protrusion is inserted into the interior of the round rod under the action of the spring. Under the action of the clamping ring and the ring groove, no leakage occurs at the connection. The clamping rod is pressed down to fix the protrusion inside the round rod, thereby achieving the effect of replacing the purification tube, thereby solving the problem of inconvenient replacement of the purification tube.
