Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to a vertical kiln flue gas desulfurization device. Background Art

[0002] With the development of industry, flue gas desulfurization equipment is increasingly being used in the field of environmental protection. As a common flue gas desulfurization equipment, vertical kiln flue gas desulfurization equipment mainly sprays desulfurizers to react harmful gases such as sulfur dioxide in the flue gas with the desulfurizers, thereby purifying the flue gas and reducing environmental pollution.

[0003] A vertical kiln flue gas desulfurization device is disclosed in announcement number CN 217139899 U, which relates to the field of flue gas purification technology. The utility model includes a water storage tank, a desulfurization tank, and a kiln. A support platform is provided at the bottom of the water storage tank. A water outlet pipe is installed at the right end of the water storage tank. A hydraulic pump is installed on the right side of the water outlet pipe. One end of the hydraulic pump is connected to the water outlet pipe, and the other end of the hydraulic pump is connected to a first transfer pipe. The inner side wall of the first transfer pipe is connected to the outer side wall of the retaining pipe. A demisting pipe is provided at the top of the desulfurization tank. A side pipe is provided on the outer side wall of the desulfurization tank. A support plate is inserted into the lower side wall of the kiln. A second transfer pipe is provided at the left end of the kiln. A second induced draft fan is installed at the left end of the second transfer pipe. By providing a first boost pipe and a second boost pipe, the utility model can atomize the desulfurization circulating liquid and capture sulfur dioxide and particulate matter in the flue gas. By providing a second transfer pipe and a second induced draft fan, the flue gas can be quickly released, effectively improving work efficiency.

[0004] The above-mentioned vertical kiln flue gas desulfurization device does not have a desulfurization tank cleaning device when in use. After long-term use, dust in the flue gas accumulates and covers the pipe wall, thereby affecting the normal operation of the desulfurization device. The manual cleaning process is very time-consuming and labor-intensive. The flue gas flow distance of the above-mentioned vertical kiln flue gas desulfurization device is extremely short, which makes the desulfurization effect of sulfur-containing flue gas poor.

[0042] The sulfur-containing flue gas flows in an S-shape in the device, which can be double-purified to improve the desulfurization quality of the sulfur-containing flue gas.

[0043] SO₂ in flue gas is acidic in nature and can be removed from the flue gas by reacting it with an appropriate alkaline substance. The most commonly used alkaline substances for flue gas desulfurization are limestone (calcium carbonate, CaCO₃), quicklime (calcium oxide, CaO), and hydrated lime (calcium hydroxide, Ca(OH)₂). Limestone is abundant and therefore relatively inexpensive, and both quicklime and hydrated lime are produced from limestone by heating. Other alkaline substances such as sodium carbonate (soda ash), magnesium carbonate, and ammonia are sometimes used. The alkaline substances used react with the SO₂ in the flue gas to produce a mixture of sulfites and sulfates (which may be calcium, sodium, magnesium, or ammonium salts, depending on the alkaline substance used).

[0044] During use, sulfur-containing flue gas enters from the bottom box 3 on the left, and then enters the cylinder 4 on the left. The fan 6 on the left is turned on to make the flue gas rise from the bottom to the top and enter the top box 5 on the right through the pipe opening. The fan 6 on the right is turned on to inject the flue gas into the cylinder 4 on the right. The spray pump 14 is turned on to allow the alkali solution to enter the spray plate through the water pipe. The atomized alkali solution is sprayed from top to bottom, thereby purifying and desulfurizing the sulfur-containing flue gas.

During the rotation of the cylinder 4, the cleaning strip 13 is always in contact with the inner wall of the cylinder 4, thereby cleaning the cylinder 4 and reducing maintenance and cleaning work.
