Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and in particular relates to a waste gas water washing tower which can improve the waste gas treatment efficiency. Background Art

[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life. Industrial waste gas usually contains pollutants such as waste gas and dust. These pollutants are usually very harmful to human health and the environment, especially chemical plants, steel mills, pharmaceutical plants, coking plants and refineries. The waste gas emitted has a strong odor, seriously polluting the environment and affecting human health. During the waste gas treatment process, water absorption, alkali absorption, resin absorption, combustion and other operations will be used according to the types of harmful components in the waste gas to ensure that the discharged waste gas meets the emission requirements; when the waste gas is subjected to water absorption operation, a waste gas water washing tower is usually used.

[0003] In the prior art, a waste gas purification water washing tower with patent announcement number CN213193182U includes a filtering device, and a plurality of spray pipes are fixed on both sides of the inner cavity of the filtering device, and one end of each of the spray pipes is fixedly connected to a diversion pipe 2. The waste gas purification water washing tower captures harmful metals in the gas and sinks them to the bottom through the atomized liquid sprayed from the spray pipe, and the clean gas is discharged through the air outlet of the top cone. The demisting net can absorb the small water droplets remaining in the gas to ensure that the dry gas is discharged. However, in actual use, there are still the following deficiencies: the air flow direction after the gas enters the tower body is a flow trajectory from bottom to top that is approximately a straight line, which results in the waste gas not staying in the tower body for a long time, so that the contact time between the waste gas and water is short, the spraying is incomplete, and the liquid after spraying contains more particulate matter, which is not easy to reuse, resulting in a waste of resources.

[0004] Therefore, there is a need for a waste gas water washing tower that can improve the waste gas treatment efficiency to solve the problems in the prior art that the contact time between the waste gas and the liquid in the water washing tower is short and the waste liquid generated after the waste gas treatment is not easy to recycle.

[0023] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the filtering mechanism 8 includes an opening 81 and two limit blocks 84 distributed in parallel. The opening 81 is opened at the bottom of the outer wall of one side of the tower body 1, and a panel 82 is slidably arranged on the bottom surface of the opening 81. A purification filter plate 83 is fixedly connected to the outer wall of one side of the panel 82. The purification filter plate 83 is located in the inner cavity of the tower body 1.

[0024] Further as Figure 2 and Figure 3As shown, it is worth explaining in detail that a sewage pipe 11 is fixedly connected to the bottom of the outer wall of the side of the liquid storage tank 6 away from the liquid inlet pipe 10, and the sewage pipe 11 passes through the outer wall of one side of the tower body 1 away from the liquid storage tank 6, and a stop valve 12 is provided on the outer side wall of the sewage pipe 11 outside the tower body 1.

[0027] In summary: when the water washing tower is in use, the exhaust gas to be treated is first introduced into the tower body 1 through the air inlet pipe 2, and the water pump 72 is turned on. After the exhaust gas enters the tower body 1, it is divided into two upward-flowing air flows by the partition 4. The upward-flowing exhaust gas is blocked by the multiple baffles 5, which extend the drifting path of the exhaust gas inside the tower body 1 and make the exhaust gas stay longer in the tower body 1. At this time, the water pump 72 extracts the liquid in the liquid storage tank 6, and transports it to the nozzle group 77 through the diversion pipe 75 and the water pipe 76 to spray the exhaust gas. The particles in the exhaust gas, that is, the harmful substances, are wrapped by the liquid and drip downward, thereby separating from the gas. The sprayed gas continues to flow upward, and finally passes through the demisting net 9 to adsorb the residual liquid in the gas. The purified and dried gas is discharged through the exhaust pipe 3, which effectively avoids the problem of poor purification effect caused by the short contact time between the exhaust gas and the liquid in the water washing tower.

[0028] After the sprayed liquid is mixed with the particles in the exhaust gas, i.e., the harmful substances, it drips to the bottom of the tower body 1, and the waste liquid is drained through the inclined baffle 5. When the waste liquid passes through the purification filter plate 83, the purification filter plate 83 purifies the waste liquid, and the purified liquid falls into the liquid storage tank 6, and is pumped out again by the water pump 72 for use, thereby realizing the recycling of the purified liquid. When the purification filter plate 83 needs to be cleaned and maintained, the staff only needs to pull the handle 87 to take out the purification filter plate 83. The operation is simple, and the problem of the waste liquid generated after the exhaust gas treatment being difficult to recycle is effectively avoided.

[0029] The water pump 72 can be purchased on the market. The water pump 72 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
