I. Brief description of the process flow of SLTC equipment SGTLC type High-efficiency desulfurization dust remover does not change the original drawing design process. Its brief is as follows:
The first stage: using a certain pressure of water, through a special ejector device, spray high-speed water mist, forming a negative pressure in the flue, generating air volume, sucking the flue gas inside the furnace, and playing a role of air. At the same time, the high-speed water mist in the flue can effectively capture and absorb dust particles, remove harmful substances such as sulfur dioxide, and then use the centrifugal force, adsorption force and inertial force of the separator to achieve the purpose of purifying the flue gas. The gas enters the second stage desulfurization and dust removal equipment.
The second stage: When the dusty flue gas enters the venturi shrinkage tube from the separator, the gas velocity gradually increases. The gas velocity in the throat is up to 55m/s, and the relative velocity of gas and liquid is large. Under the impact of high-speed airflow, the water droplets sprayed from the clear water nozzle in front of the venturi throat are highly atomized, and the high-speed low pressure at the throat causes the airflow to be supersaturated, and the air film attached to the surface of the dust particles is broken and burst. The dust particles are wetted by water. Therefore, there is a fierce collision and condensation between dust particles and water droplets or dust particles and dust particles. After entering the diffusion section from the throat, the speed decreases, the static pressure rises, and the condensation of supersaturated steam with dust particles as condensation nuclei proceeds quickly. The condensed water particles continue to condense and collide, and the small particles condense into large particles, and then the flue gas with a flow rate of about 20m/s enters the multi-tube water film dust removal stage from the tangential direction, and the flue gas enters the multi-tube stage and then the large-area airflow The water film formed by the small-surface airflow product passing through the spray on the multi-tube is flushed into the water. Because the venturi tube is equipped with a water spray system in front of the throat and an alkali spray system behind the throat and a multi-tube split air film system, so that the smoke in the flue gas is wet by water, SO2 is also highly atomized. The alkali mist is wet, so that the SO2 in the flue gas is in contact with the lye in the venturi tube and the multi-tube, so that the SO2 in the flue gas has a sufficient reaction time with the alkali hydrazine.
The third stage: the flue gas after the first stage venturi and multi-tube water film desulfurization and dedusting enters the SGTLC type water bath for the second stage desulfurization and dust removal. When the flue gas is flushed into the SGTLC type water bath through multiple tubes, the dust particles are settled by gravity. The principle is precipitated into water, and at the same time, sufficient countercurrent contact with the lye from the desulfurization circulating tank is carried out. Under the interaction of gas and liquid, a boiling layer of lye of 400-500 mm is formed on the water bath, and the flue gas passes through the water bath. Entering the boiling layer, the gas and liquid have a long contact time and a large contact area, so that the first stage unremoved fine dust is trapped by water, and the first few stages are not absorbed by the SO2 and the water bath. The lye is fully reacted and absorbed.
The fourth stage: the flue gas enters the upper swirl plate type desulfurization and dust removal system after passing through the second-stage water bath. When the flue gas enters the gap between the two swirl sheets, the air flow guiding effect of the swirl plate and the upward spiral of the flue gas itself are utilized. The movement blows and atomizes the desulfurization liquid on the swirl plate to form an ideal atomization area on the upper part of the swirl. The desulfurization absorption liquid in the region exists in the droplets of several tens of micrometers, which greatly increases the gas-liquid contact area, thereby ensuring that the SO2 in the flue gas is sufficiently dissolved and absorbed by the alkaline absorption liquid, and the originally small amount of smoke in the flue gas is again It is washed by the absorption liquid to obtain higher dust removal and desulfurization efficiency.
The fifth stage: Finally, the purified gas is removed by a dehumidifier and a dehumidifying device to remove water mist, so that the fan does not have a water mist phenomenon, and the operating life of the induced draft fan is ensured.
