Description

Technical Field

[0001] The utility model relates to the technical field of water scrubbers, in particular to a high-efficiency and energy-saving tail gas water scrubber with controllable gas flow direction. Background Technique

[0002] Industrial waste gas usually contains pollutants such as harmful gases and dust, which generally pose great harm to human health and the environment. For example, these pollutants enter the human body through respiration, skin contact and the digestive tract, which can lead to endocrine dysfunction and affect the immune function, cardiovascular and central nervous systems of the human body. Therefore, the problem of waste gas treatment has received great attention.

[0003] A plurality of spray systems are installed in the tail gas water scrubber, and most of the spray systems adopt disc spray systems to wash the rising tail gas. However, in the actual process, the flow direction of the tail gas in the tower body is relatively dispersed, and generally the flow direction of the tail gas cannot be well controlled. Therefore, this leads to a poor water washing effect when washing the tail gas. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a high-efficiency and energy-saving tail gas water scrubber with controllable gas flow direction to solve the problem that a plurality of spray systems are installed in the tail gas water scrubber in the above background technique. Most of the spray systems adopt disc spray systems to wash the rising tail gas. However, in the actual process, the flow direction of the tail gas in the tower body is relatively dispersed, and generally the flow direction of the tail gas cannot be well controlled. Therefore, this leads to a poor water washing effect when washing the tail gas.

[0005] To achieve the above object, the utility model provides the following technical solution: A high-efficiency and energy-saving tail gas water scrubber with controllable gas flow direction, including a tower body. A water storage cavity is opened at the bottom of the tower body. Four support legs are fixedly installed at the bottom of the water storage cavity. The four support legs are arranged in a circumferential array in the water storage cavity. A liquid discharge port is opened at the bottom of the water storage cavity. A diversion pipe is arranged at a position closer to the bottom in the tower body. An air inlet is opened at the head end of the diversion pipe. The air inlet penetrates through the tower body and extends to the outer end of the tower body. The diversion pipe spirally rises in the tower body. An air outlet is opened at the top end of the diversion pipe. A liquid discharge pipe is opened at the bottom of the diversion pipe.

[0006] With the above technical solution, the impurities in the carried tail gas are stored through the water storage cavity opened at the bottom of the tower body. Then, since there is a liquid discharge port opened at the bottom of the water storage cavity, the flushing liquid carrying the impurities in the tail gas can be discharged through the liquid discharge port. Then, the four support legs installed at the bottom of the water storage cavity and arranged in a circular array can better support the tower body. Then, when it is necessary to wash the tail gas, first send the tail gas into the diversion pipe through the air inlet. Then, because the diversion pipe is spirally rising, the tail gas will be discharged through the air outlet opened at the top end of the diversion pipe.

[0007] Preferably, a spiral water washing pipe is arranged at a position relatively close to the bottom inside the tower body. The spiral water washing pipe is located at the outer end of the diversion pipe. A connecting pipe is fixedly installed at the inner end of the spiral water washing pipe. The other ends of the connecting pipes are all connected inside the diversion pipe. The other end of the spiral water washing pipe is provided with a first liquid inlet pipe, and the first liquid inlet pipe penetrates through the tower body and extends outside the tower body.

[0008] With the above technical solution, there is a spiral water washing pipe arranged at the outer end of the diversion pipe, and the other end of the connecting pipe installed at the inner end of the spiral water washing pipe is connected inside the spiral water washing pipe. Therefore, when the staff injects the flushing liquid into the first liquid inlet pipe, the flushing liquid will be sent into the diversion pipe through the connecting pipe. Then, after the flushing liquid enters the diversion pipe, it will remove the impurities in the rising tail gas in the diversion pipe. Then, the flushing liquid carrying particulate impurities will be discharged through the liquid discharge pipe opened at the bottom of the diversion pipe, so as to enter the water storage cavity.

[0009] Preferably, a gas guiding structure is arranged at the middle position inside the tower body. A first gas guiding groove is opened at the bottom position of the gas guiding structure, a second gas guiding groove is opened at the top end of the gas guiding structure, and through holes are opened between the first gas guiding groove and the second gas guiding groove.

[0010] With the above technical solution, after the tail gas enters the gas guiding structure, the tail will enter the second gas guiding groove through the first gas guiding groove, so as to perform secondary water washing on the tail gas, thereby improving the water washing effect of the tail gas.

[0011] Preferably, an annular pipe is arranged at a position relatively close to the top inside the tower body. A second liquid inlet pipe is arranged on one side of the annular pipe. The second liquid inlet pipe penetrates through the tower body and extends outside the tower body. A plurality of atomizing nozzles are installed at the bottom of the annular pipe.

[0012] With the above technical solution, by connecting the second liquid inlet pipe to an external water source, the flushing liquid is sent into the annular pipe. Then, because a plurality of atomizing nozzles are installed at the bottom of the annular pipe, the flushing liquid will be sprayed out through the atomizing nozzles, so as to perform secondary flushing on the tail gas, thereby improving the water washing effect on the tail gas.

[0013] Preferably, a demister is provided near the top inside the tower body. The top of the tower body is conical, and an exhaust port is provided at the top of the tower body.

[0014] With the above technical solution, after the tail gas passes through the water wash, it will pass through the demister. When the tail gas passes through the demister, the remaining moisture in the tail gas will be removed by the demister. Then, when the tail gas passes through the demister, it will become dry. After the moisture in the tail gas is removed, it will be discharged through the exhaust port provided at the top of the tower body. Then, the top of the tower body is conical, so that the tail gas can be better discharged.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. For this high-efficiency energy-saving tail gas water wash tower with controllable gas flow direction, the tail gas is sent into the diversion pipe through the air inlet. After the tail gas is sent into the diversion pipe, the staff injects the flushing liquid into the first liquid inlet pipe. Then, the flushing liquid will be sent into the diversion pipe through the connecting pipe. After the flushing liquid enters the diversion pipe, it will remove the impurities in the rising tail gas in the diversion pipe. Then, the flushing liquid carrying particulate impurities will be discharged through the drain pipe provided at the bottom of the diversion pipe, so as to enter the water storage cavity and be discharged therefrom. At the same time, the diversion pipe can also better control the flow direction of the tail gas.

[0017] 2. For this high-efficiency energy-saving tail gas water wash tower with controllable gas flow direction, the second liquid inlet pipe is connected to an external water source to send the flushing liquid into the annular pipe. Since a plurality of atomizing nozzles are installed at the bottom of the annular pipe, the flushing liquid will be sprayed out through the atomizing nozzles to perform a secondary flushing of the tail gas, so as to improve the effect of washing the tail gas with water. After the tail gas passes through the water wash, it will pass through the demister. When the tail gas passes through the demister, the remaining moisture in the tail gas will be removed by the demister. Then, when the tail gas passes through the demister, it will become dry.
