" multistage multibarrel backset " remove dust desulphurization craft
Traditional wet flue gas removes dust desulphurization craft is general form of characters or letters of tower of the place outside be, be opposite in tower system interior through lye of flue gas gush drenchs, the purpose that catharsis achieves sulfur of the 2 oxidation in dividing flue gas. Because fluid is enraged in this one process,small, slow, impact force spent two interface to bring about the result with low efficiency not quite. If why handle this problem,be one of tasks that environmental protection Scientists and Technologists solves urgently all the time. Civil Qiu Li is the person that solve this difficult problem the earliest, with high speed the air current that contain dirt passes trunnion, water is in infuse in trunnion and by pulverization of high speed air current, the impurity in gas and water collide each other make sedimentation, its remove dust efficiency is highest can achieve 99% . The pulverization of this shows water and gas fluid two between the size how that pounds impact force is important. Dan Wenshi canal is put in a the heel of Achilles again, already resistance is too great bad news can be exorbitant, still must add dehydrator alone, also bring certain difficulty to actual application so. " multistage multibarrel backset " remove dust the settlement with desulphurization very good craft difficult problem of this one craft, the detailed process of this one craft is below.
1, design academic keyword: Pulverization, intercept, collision, agglomeration, absorb, diffuse.
2, design thought keyword: Low block, efficient.
3, basic structure:
Larynx of pulverization of much unit of inlet plenum, 3 class, 3 class are much uniter eddy current board, 3 class are much uniter system of room of conduit of swirl chamber, dehydration board, circumfluence, exhaust, boiler circulation.
4, working principle:
Inlet plenum: The gas that contain dirt and water from this and into, gas and water even allocation arrives larynx of much uniter pulverization.
Larynx of pulverization of 3 class much unit: Pulverization larynx promotes brother's son every second aeriform velocity of flow 30 meters, because enrage fluid,humidity of very expensive gas achieves two relative speed saturated, fluid shape of the mist that be become by air current concussion, the gas film that grit surface adheres to is broken through and by water wet, process of the pulverization that finish. Two herein pound gas fluid each other mutual collision becomes mixture steam, make the impurity in gas sedimentations, intense agglomeration happens between grit and water or grit and grit. The NaOH in the SO2 in compulsive gas and water or Ca (OH) 2 happen counteract reaction to generate sulfate.
3 class are much uniter eddy current board: Eddy current board designs cone (can reduce obstruction) , mixture steam passes eddy current board to eddy current arises when haul bypasses eddy current board moves again and make air current produces rapid to move at the same time, increase gas fluid two mutual concussion collides each other opportunity.
