Abstract
A flue gas even distribution device for desulfuration spray tower, relates to flue gas desulfurization device technical field.The utility model is inhomogeneous in order to solve in existing desulfuration spray tower smoke distribution, the large problem of flue gas resistance in tower.Scheme: flue gas even distribution device is arranged on the interior smoke inlet of tower, under bottom spraying layer, comprise many tube banks, the cross sectional shape of tube bank is inverted droplet-shaped, tube bank is horizontal, make the flue gas flow area that between tube bank, Formation cross-section is irregular venturi-shaped, there is brace summer the below of tube bank, and brace summer is fixedly connected on the tower wall of spray column.The utility model can make the interior smoke distribution of tower even, and strengthening gas-liquid mass transfer, improves desulfuration efficiency, and caused flue gas resistance increase is less, and has the features such as simple in structure, cost is low.
Description
Technical field
The utility model relates to a kind of flue gas uniform device, specifically relates to a kind of flue gas even distribution device of desulfuration spray tower, belongs to flue gas desulfurization device technical field.
Background technology
In the flue gas of coal fired boiler of power plant discharge, contain a large amount of sulfur dioxide, if sulfur dioxide is just directly discharged in atmosphere huge to the harm of environment and person health without strictly removing processing.Thermal power plant is according to all canceling gas bypass of the requirement of environmental administration, solar obligation flue gas desulfur device, and wet desulfurization of flue gas by limestone-gypsum method technology is the most ripe current sulfur removal technology, has become heat-engine plant desulfurized one preferred technique both at home and abroad.And spray column is the main flow tower on current wet desulfurization of flue gas by limestone-gypsum method absorption tower, there is the remarkable advantages such as desulfuration efficiency is high, tower inner member is few, resistance is low.In desulfuration spray tower, flue gas is entered in tower along the flue that has a down dip by tower bottom import cross section, and flue gas rises in tower, and in tower, Yu Congta top in uptake zone sprays downward desulfurization slurry adverse current and fully contacts and reach the object that removes sulfur dioxide in flue gas.Spray column, owing to being that the size of void tower structure and tower is larger, makes smoke distribution inhomogeneous in tower, can reduce to a certain extent like this desulfuration efficiency.Certain main flow desulfurization company adopts installs Venturi rod layer in desulfurizing tower bottom, can strengthen gas-liquid mass transfer, significantly improves smoke distribution situation, but can increase largely flue gas resistance in tower.
Utility model content
The utility model is inhomogeneous for solving the interior smoke distribution of existing desulfuration spray tower, the large problem of flue gas resistance in tower, provide one can make the interior smoke distribution of tower even, the flue gas resistance increase causing is less, thereby improves the flue gas even distribution device of the desulfuration spray tower of desulfuration efficiency.
The utility model for solving the problems of the technologies described above taked technical scheme is:
The flue gas even distribution device of a kind of desulfuration spray tower of the present utility model is arranged on the interior smoke inlet of tower, under bottom spraying layer, comprise many tube banks, the cross sectional shape of tube bank is inverted droplet-shaped, tube bank 1 is horizontal, horizontal mode makes the flue gas flow area that between tube bank, Formation cross-section is irregular venturi-shaped, and there is brace summer the below of tube bank, and brace summer is fixedly connected on the tower wall of spray column.
In such scheme, restraining cross sectional shape is inverted water-drop-shaped, tube bank is horizontal, horizontal mode makes to form between tube bank the flue gas flow area of irregular venturi-shaped, flue gas by flow area after along rising in tower and spraying downward slurries and contact.The flue gas even distribution device of this structure can be strengthened gas-liquid mass transfer, make smoke distribution in tower become very even, realize air-flow in absorption tower is carried out to effective rectification, thereby improve desulfuration efficiency, and can improve to a certain extent flue gas ash removal effect, its another significant advantage is exactly that flue gas resistance increase is less.
Scheme is further designed: in order to make in tower smoke distribution more even, the spacing between tube bank equates, the spacing between tube bank is defined as the horizontal size at narrow place of two flow areas between tube bank.
Scheme is further designed: for the effect of better performance tube bank, the integral width of tube bank is 50-100mm, and whole height is 150-400mm.
Scheme is further designed: in order to bring into play the effect of flue gas flow area, the spacing between tube bank is 20-80mm.
Scheme is further designed: in order to make in tower smoke distribution more even, the direction that the interval between tube bank enters tower body along flue gas reduces gradually.
Scheme is further designed: for the effect of better performance tube bank, the integral width of tube bank is 50-100mm, and whole height is 150-400mm.
Scheme is further designed: in order to bring into play the effect of flue gas flow area, the spacing between tube bank enters tower body direction along flue gas is decreased to the 20mm of opposite side gradually by the 80mm of a side.
Scheme is further designed: for the ease of installing, tube bank is made up of multistage pipe.
The utility model can be strengthened gas-liquid mass transfer, make smoke distribution in tower become very even, realize air-flow in absorption tower is carried out to effective rectification, thereby improve desulfuration efficiency, and can improve to a certain extent flue gas ash removal effect, its another significant advantage is exactly that flue gas resistance increase is less, can be used as flue gas desulfurization device and extensively promotes.
