Description

Technical Field

[0001] The invention relates to a chemical waste gas treatment and tail-end carbon dioxide treatment device, belonging to the technical field of chemical waste gas treatment. Background Art

[0002] At present, the RTO (regenerative thermal oxidizer) waste gas treatment process will produce a large amount of carbon dioxide gas in the process of burning organic gas. The specific process is mainly as follows: the waste gas enters the direct-fired furnace, heats up after passing through the heat storage body, and then passes through the burner to heat up to above 760℃. Under the action of high temperature, it burns and decomposes the organic matter into carbon dioxide and water. After cooling through the heat storage body, it is finally discharged into the atmosphere through the fan and chimney.

[0003] There are still some problems in the use of an existing chemical waste gas treatment device. For example, when treating exhaust gas, the air duct needs to be connected to the inside of the equipment to guide the exhaust gas into the interior of the equipment. However, the existing connection mechanism is relatively complicated and troublesome to install. When filtering the exhaust gas, dust is easily accumulated on the surface of the filter plate, causing blockage, which in turn affects the purification efficiency of the equipment. After filtering the dust, carbon dioxide gas still exists in the gas, and direct discharge will pollute the air. Summary of the Invention

[0004] The purpose of the present invention is to provide a chemical waste gas treatment and tail-end carbon dioxide treatment device. The present invention has a simple structure and is easy to use. The air duct can be quickly connected to facilitate the introduction of gas. When the filter plate is used to filter impurities in the air, the filter plate is automatically cleaned. At the same time, the carbon dioxide gas can be purified to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A chemical waste gas treatment and tail-end carbon dioxide treatment device includes a body shell, the bottom of the body shell is fixedly connected to a support block, the outside of the body shell is fixedly connected to a controller, the top of the body shell is fixedly connected to an air intake pipe, the inside of the air intake pipe is clamped with an air guide pipe, the outside of the air intake pipe is fixedly connected to an L-shaped plate, the outside of the L-shaped plate is fixedly connected to a threaded pipe, the inside of the threaded pipe is threadedly connected to a screw, the outside of the screw is fixedly connected to a rotating cover, the outside of the screw is fixedly connected to a push rod, the inside of the L-shaped plate is fixedly connected to a compression spring, and the outside of the compression spring is fixedly connected to a sealing clamping cover.

[0007] Furthermore, a motor is fixedly installed on the outside of the body shell, a screw rod is fixedly connected to the output end of the motor, a bolt is threadedly connected to the outside of the screw rod, the top of the bolt is fixedly connected to a limit rod, the bottom of the bolt is fixedly connected to a guide rod, the bottom of the guide rod is fixedly connected to a cleaning plate, and a filter plate is fixedly connected to the inside of the body shell, and a discharge chute is provided inside the filter plate.

[0008] Furthermore, a connecting rod is fixedly connected to the outside of the body shell, a sodium hydroxide solution tank is fixedly connected to the outside of the connecting rod, an extraction pump is fixedly connected to the outside of the body shell, a through pipe is fixedly connected to the top of the extraction pump, a sealing disk is clamped on the top of the sodium hydroxide solution tank, and a scale plate is fixedly connected to the outside of the sodium hydroxide solution tank.

[0009] Furthermore, the support blocks are symmetrically distributed on the bottom of the body shell, and the L-shaped plates are symmetrically distributed on the outside of the air intake pipe.

[0010] Furthermore, the push rod passes through the interior of the L-shaped plate, the compression spring is symmetrically distributed between the L-shaped plate and the sealing clamping cover, and the push rod and the sealing clamping cover are on the same plane.

[0011] Furthermore, the motor is electrically connected to the controller, the screw rod is rotatably connected to the inside of the body shell, and the top of the limit rod is slidably engaged in the inner top wall of the body shell.

[0012] Furthermore, the cleaning plate is movably connected to the top of the filter plate through a guide rod, and the discharge chute is located on one side of the interior of the cleaning plate.

[0013] Furthermore, the extraction pump is electrically connected to the controller, and the sodium hydroxide solution tank is fixedly connected to the outside of the body shell through a connecting rod.

[0014] Furthermore, the sodium hydroxide solution tank stores sodium hydroxide solution, and one end of the through pipe away from the extraction pump is fixedly connected to the interior of the sodium hydroxide solution tank.

[0015] The beneficial effects of the present invention are:

[0016] (1) The present invention is provided with a body shell, and an air intake pipe is fixedly connected to the top of the body shell. First, the air guide pipe is clamped to the inside of the air intake pipe, and the rotating cover is rotated to drive the screw to move inside the threaded pipe. The screw drives the push rod to move, thereby pushing the sealing clamping cover on the outside of the compression spring, so that the sealing clamping cover is tightly attached to the outside of the air intake pipe and the air guide pipe. At this time, they can be clamped, achieving the effect of convenient clamping.

[0017] (2) The present invention is provided with a body shell, and the exhaust gas is transported to the interior of the body shell through the air duct. Since a filter plate is fixedly connected to the interior of the body shell, impurities in the exhaust gas can be filtered. When the two sealing clamping covers are close to each other, the elastic switch on the outside of the sealing clamping cover on one side will be squeezed, so that the controller will start the motor. At this time, the motor drives the screw rod to rotate inside the body shell. Since a bolt is threadedly connected to the outside of the screw rod, and a limiting rod is fixedly connected to the top of the bolt, and the top of the limiting rod is slidably connected to the inner top wall of the body shell, the limiting rod can limit the bolt. When the screw rod rotates, it can drive the bolt to move. At this time, the bolt and the guide rod are used in conjunction to move the cleaning plate on the top of the filter plate, and clean the impurities to the inside of the body shell through the discharge chute, thereby preventing blockage.

[0018] (3) The present invention is provided with a body shell, and a sodium hydroxide solution tank is fixedly connected to the outside of the body shell by a connecting rod. The extraction pump is started by a controller, so that the filtered gas is transported to the interior of the sodium hydroxide solution tank through a through pipe. Since the sodium hydroxide solution is stored in the sodium hydroxide solution tank, the carbon dioxide in the exhaust gas can be neutralized through a chemical reaction, thereby preventing the carbon dioxide from being directly discharged and causing air pollution.

[0032] Example 2

[0033] See also Figure 1 、 Figure 2 and Figure 6 The difference between this embodiment and embodiment 1 is that a motor 13 is fixedly mounted on the outside of the body shell 1, a screw rod 14 is fixedly connected to the output end of the motor 13, a bolt 15 is threadedly connected to the outside of the screw rod 14, a limit rod 16 is fixedly connected to the top of the bolt 15, a guide rod 17 is fixedly connected to the bottom of the bolt 15, a cleaning plate 18 is fixedly connected to the bottom of the guide rod 17, a filter plate 19 is fixedly connected to the inside of the body shell 1, and a discharge chute 20 is opened inside the filter plate 19.

[0035] Example 3, please refer to Figure 1 、 Figure 2 and Figure 5 The difference between this embodiment and embodiment 1 is that: a connecting rod 21 is fixedly connected to the outside of the body shell 1, a sodium hydroxide solution tank 22 is fixedly connected to the outside of the connecting rod 21, an extraction pump 23 is fixedly connected to the outside of the body shell 1, a through pipe 24 is fixedly connected to the top of the extraction pump 23, a sealing disk 25 is clamped on the top of the sodium hydroxide solution tank 22, and a scale plate 26 is fixedly connected to the outside of the sodium hydroxide solution tank 22.
