Description
Technical Field
The invention relates to a desulfurizing tower and a desulfurizing method thereof, which are mainly used for desulfurizing flue gas.
Background
Flue gas generally refers to a mixture of gas and smoke. The operation of chemical plants such as boilers, industrial kilns, thermal power plants, coke ovens, cement plants, blast furnaces, open-hearth furnaces, converters, electric furnaces, and catalytic cracking (FCC) units produce significant amounts of flue gas. Air pollutants such as sulfur oxides and nitrogen oxides contained in flue gas bring about a series of environmental problems. Therefore, the flue gas must be desulfurized, denitrated and dedusted before being discharged.
The desulfurizing tower is the most commonly used equipment in the flue gas desulfurization treatment at present, and current desulfurizing tower generally contains the digester, and sets up at least two sets of absorption liquid spraying mechanism in the digester according to the height, and flue gas flows through the digester from bottom to top. The absorption liquid at the bottom of the desulfurizing tower is pumped and discharged to the position of the absorption liquid spraying mechanism through corresponding liquid pumping circulation, and the absorption liquid is atomized and sprayed out, so that the atomized absorption liquid is contacted with the flue gas flowing through the desulfurizing tank and reacts with the flue gas, and the desulfurizing effect is achieved. Because upward air flow can be formed in the upward exhaust process of the flue gas, the circulation speed is high, and the atomized absorption liquid is easy to cause that the absorption liquid cannot be uniformly distributed in the desulfurization tank, so that the desulfurization effect is not ideal.
Therefore, the circulation speed of the smoke can be greatly reduced by designing a device so as to effectively prolong the contact time of the smoke and the atomized absorption liquid; the desulfurization tower and the desulfurization method thereof can effectively ensure the distribution uniformity of the atomized absorption liquid so as to effectively improve the contact rate of the flue gas and the atomized absorption liquid, thereby effectively improving the desulfurization effect and the desulfurization efficiency.
