Description

Technical Field

[0001] The invention relates to the technical field of waste gas alkali washing, and in particular to a horizontal alkali washing device and a use method thereof. Background Art

[0002] In the prior art, the acid gas discharged from the top of the glue tank is usually treated by an alkali scrubber. The alkali scrubber is a device for gas purification, which mainly removes acidic substances in the gas through acid-base neutralization reaction. During operation, the gas phase in the glue tank enters from the middle and lower part of the tower, and the circulating alkali liquid is injected from the top of the tower through a circulating pump to form a top-down flow. In this way, the acid gas from the bottom to the top and the alkali liquid from the top to the bottom are fully contacted and the acid-base neutralization reaction is carried out on the tower plate;

[0003] Although alkali washing towers are widely used in industrial applications, they have several major problems. First, due to the relatively short residence time of the alkali solution in the tower, the alkali washing effect is usually not ideal. The contact time between the alkali solution and the acidic gas is not enough to achieve complete acid-base neutralization, so the utilization efficiency of the alkali is not high. Secondly, this operation mode leads to a large consumption of alkali solution, which in turn produces a large amount of alkali discharge and corresponding hazardous waste, increasing the treatment cost and environmental burden. Summary of the invention

[0004] The present application aims to solve one of the technical problems in the related art at least to some extent.

[0005] To this end, the first purpose of the present application is to solve the problem of traditional horizontal alkali washing device and its use method. The mixture of acidic gas and cold oil that has been fully alkali washed can be overflowed from the top of the last reaction chamber to the oil-alkali separation tank for separation, and the separated alkali liquid is returned to the horizontal tank with stirring through an alkali liquid circulation pump for recycling. Thus, the acid corrosion problem of the device is alleviated, and the utilization efficiency of the alkali is very high. It is only necessary to control the alkali concentration in the horizontal tank with stirring. When the alkali concentration is lower than the control range, a certain amount of alkali liquid can be added.

[0042] The horizontal alkali washing device and its use method of the embodiment of the present application are described below with reference to the accompanying drawings.

[0043] The embodiments of the present application provide a horizontal alkali washing device and a method of using the same. The device can separate a mixture of acidic gas and cold oil that has been sufficiently alkali washed by overflowing from the top of the last reaction chamber to the oil-alkali separation tank 242. The separated alkali liquid is returned to the horizontal tank with stirring through an alkali liquid circulation pump for recycling. Thus, the acid corrosion problem of the device is alleviated, and the utilization efficiency of the alkali is very high. It is only necessary to control the alkali concentration in the horizontal tank with stirring. When the alkali concentration is lower than the control range, a certain amount of alkali liquid can be added. There is no need to discharge the waste alkali regularly, the amount of hazardous waste is low, and the operation cycle is long.

[0044] like Figure 1-Figure 8 As shown, the horizontal alkali cleaning device and the use method thereof of the embodiment of the present application may include a supporting base 1, a horizontal alkali cleaning mechanism 2 and an air intake duct 3.

[0045] The horizontal alkali cleaning mechanism 2 is installed on the top of the supporting base 1 , and the air inlet pipe 3 is installed on the horizontal alkali cleaning mechanism 2 .

[0046] It should be noted that the support base 1 described in this embodiment is symmetrically fixedly connected to the two sides with guardrails, and one end of the air intake pipe 3 is connected to the top of the glue tank, so that the exhaust gas discharged from the top of the glue tank can be transported through the air intake pipe 3.

[0047] The horizontal alkali washing mechanism 2 comprises a cold oil absorption component 21 , a salt cooling component 22 , an alkali washing component 23 and an oil-alkali separation component 24 .

[0048] Among them, the cold oil absorption component 21, the salt cooling component 22, the alkali washing component 23 and the oil-alkali separation component 24 are all installed on the supporting base 1, the end of the cold oil absorption component 21 is connected to the end of the salt cooling component 22, the end of the salt cooling component 22 is connected to the end of the alkali washing component 23, the end of the alkali washing component 23 is connected to the oil-alkali separation component 24, and the oil-alkali separation component 24 can return the separated alkali solution to the alkali washing component 23 through the alkali solution circulation pump for recycling.

[0049] It should be noted that the exhaust gas described in this embodiment passes through the cold oil absorption component 21, the salt cooling component 22, the alkali washing component 23 and the oil-alkali separation component 24 in sequence, thereby effectively improving the effect of alkali washing. At the same time, the oil-alkali separation component 24 returns the separated alkali liquid to the alkali washing component 23 through the alkali liquid circulation pump for recycling. Therefore, the utilization efficiency of the alkali is very high. It is only necessary to control the alkali concentration of the alkali washing component 23. When the alkali concentration is lower than the control range, a certain amount of alkali liquid can be added. There is no need to discharge the waste alkali regularly, and the amount of hazardous waste is low.

[0050] The air intake pipe 3 is mounted on the cold oil absorption assembly 21 .

[0051] It should be noted that, when the exhaust gas is transported through the air intake pipe 3 as described in this embodiment, the exhaust gas can be cooled by the cold oil absorption component 21. At the same time, the acidic gas on the top of the glue tank can also be absorbed by the cold oil, and the acidic components in the gas are dissolved and absorbed by the cold oil, thereby purifying the gas.

[0052] Specifically, the waste gas is processed in turn through the cold oil absorption component 21, the salt cooling component 22, the alkali washing component 23 and the oil-alkali separation component 24, and then the alkali solution separated by the oil-alkali separation component 24 is returned to the horizontal tank with stirring through the alkali solution circulation pump for reuse. This recycling process not only saves resources but also reduces operating costs. At the same time, through the cold oil absorption component 21, the salt cooling component 22 and the alkali washing component 23, the acidic gas can be effectively converted into harmless substances in the multi-stage stirring and reaction process, and the utilization efficiency of the alkali solution is optimized.

At the same time, when the exhaust gas is transported, the cold oil can be extracted through the first pump body 213 and sprayed through multiple spray heads. Therefore, after the acidic gas is absorbed by the cold oil, the acidic components in the gas are dissolved and absorbed by the cold oil, thereby purifying the gas, and the exhaust gas can also be cooled synchronously.

[0063] Specifically, in order to cool the exhaust gas and thus ensure the effect of subsequent alkali washing, the exhaust gas can be cooled by salt cooling through the cooling tank 222, and then under the action of the third pump body 223, the cooled exhaust gas can be transported to the alkali washing component 23 through the output pipe 225 for subsequent operations, thereby effectively improving the effect of alkali washing.
