Description

The invention relates to the technical field of dust and mist separation, in particular to a condensing, dedusting and demisting device for flue gas of a sintering machine.
Background
In 2018, in Hebei, Shanxi, Tianjin and the like, heavy-spot industry atmospheric pollutant depth treatment files such as steel sintering machines, coking, coal-fired power plant boilers and the like are produced in succession. The gypsum rain and the colored smoke plume are required to be treated in the document, the emission temperature and the moisture content of the smoke are reduced through corresponding technologies, the moisture in supersaturated water vapor in the smoke is collected, and the emission of condensable particles such as soluble salt, sulfuric acid mist and organic matters in the smoke is reduced.
Handan city issued an implementation scheme for advanced treatment of air pollution in key industry of industrial enterprises in 2020 of Handan city in 3 months in 2020, and the scheme requires that the emission concentration of particulate matters in sintering machine heads in the steel industry is not higher than 10mg/Nm 3.
The flue gas characteristics of the head of the sintering machine contain SO2, NOx and particulate matters, the requirement on NOx emission indexes in the flue gas is not strict in the early national environmental protection policy, most sintering machines are not provided with a denitration device, and the established sintering machine mostly adopts the combined technology of an electrostatic dust collector, wet desulphurization (comprising a limestone/lime-gypsum method, an ammonia method, a double alkali method and the like) and a wet electric dust collector for treating SO2 and particulate matters in the flue gas.
When the outlet effect of the electrostatic dust collector for the head flue gas of the sintering machine is good at present, the emission concentration of particulate matters can be controlled to be about 50mg/Nm3 and normally about 80mg/Nm3, and in combination with a following wet electric dust collector, the emission concentration of the particulate matters at the terminal can be controlled to be about 15mg/Nm3 and cannot reach below 10mg/Nm3, so that the emission concentration of the particulate matters is not higher than 10mg/Nm3 in the current environmental protection policy, and the emission concentration of the particulate matters is in the following part of regions.
The traditional condensation dedusting and demisting method is that after wet desulphurization, the flue gas of a sintering machine head is provided with a water spray cooling layer and an independent demister layer in the top of a desulphurization tower (the upper part of a desulphurization slurry spray layer) or a flue behind the desulphurization tower, and a water collecting tray is arranged between the desulphurization spray layer and the water spray cooling layer.
The prior art has the problems that: firstly, the water of cooling usefulness and high temperature flue gas direct contact have increased the droplet volume in the flue gas when reducing gas temperature, have increaseed the defogging pressure of follow-up defroster, lead to the flue gas to take water seriously, influence rear end equipment. And secondly, the water collecting disc increases the smoke resistance, so that the fan has high requirement on output and high running power consumption. Thirdly, the liquid drops collected by the water collecting tray are provided with most of slurry particles, all water cooling systems need to select corrosion-resistant and wear-resistant materials, and an independent cooling water treatment system is also needed. Fourthly, the water consumption of the system is greatly increased due to the cooling of the water spray, and the water balance of the whole system cannot be ensured. Fifthly, due to the characteristic of sintering flue gas, the traditional demisting device is easy to block, and once the demisting device is blocked, the device can be overhauled only after the unit stops running and under the condition that no flue gas passes through.
In view of the above, the prior art is obviously inconvenient and disadvantageous in practical use, and needs to be improved.
