Description
Technical field
This utility model belongs to flue gas desulfurization technique field, is specifically related to a kind of desulfurizing tower being applicable to ultra-clean discharge.
Background technology
" fossil-fuel power plant atmospheric pollutant emission standard " (GB13223-2011) specifies, from 1 day July in 2014, new construction of coal-fired boiler sulfur dioxide in tail gas emission limit was 100mg/Nm3, key area emission limit is 50mg/Nm3。
At present in the coal-fired process of power industry, the SO of generation2Administering method based on limestone gypsum wet, but, with the desulfurizing tower of current technical support, exist air flow method not uniformly, gas-liquid mass transfer efficiency low, and lime slurry concentration at wall flow phenomenon, i.e. tower wall is low compared to tower central authorities, along the SO of tower wall vertical ascent2Can not be caused discharging some problems such as grade the most up to standard by absorbing fully.The existence of these problems makes desulfurizing tower purification efficiency can not reach initial design values, exiting flue gas SO2Concentration is it is possible that discharge situation about exceeding standard.
Summary of the invention
The purpose of this utility model is the problem existed for existing desulfurizing tower, it is provided that a kind of desulfurizing tower being applicable to ultra-clean discharge.
Technical solution of the present utility model is: a kind of desulfurizing tower being applicable to ultra-clean discharge, including tower body, be provided with slurry pool in the bottom of tower body, slurry pool be arranged over smoke inlet, the top of tower body arranges exhanst gas outlet, inside tower body, above smoke inlet, being sequentially arranged airflow-distribution board, gas-liquid distribution ball, atomization sprayer, demister from bottom to top, gas-liquid distribution ball is arranged on the inwall of tower body, being evenly distributed with through hole on airflow-distribution board, demister is ridge type demister；Airflow-distribution board, gas-liquid distribution ball, atomization sprayer；Can repeatedly arrange in this order to improve desulfuration efficiency in tower body.
Further, described airflow-distribution board is broken-line type tabular.
Further, described airflow-distribution board broken-line type bending angle is 90 ° ~ 120 °.
Further, the through hole on described airflow-distribution board is circular hole or square hole or irregular hole.
Further, on described airflow-distribution board the percent opening of through hole for for 60% ~ 70%.
Further, described gas-liquid distribution ball is hemispherical or ellipsoid shape.
Further, described gas-liquid distribution ball is interrupted on tower wall and is uniformly distributed.
The beneficial effects of the utility model are: by setting up airflow-distribution board and the gas-liquid distribution ball of a kind of improvement, airflow-distribution board can the most uniform flow field in tower, in making tower, air flow method is more uniform, and the alkali liquor of atomization sprayer ejection simultaneously forms liquid film, SO on the small sircle hole of airflow-distribution board2Carry out the most sufficiently reaction with alkali liquor, reach more preferably mass transfer effect；It addition, gas-liquid distribution ball improves concentration and the gas-liquid mass transfer time of lime slurry at tower wall, decrease the SO escaped along tower wall2Amount, improves gas cleaning efficiency；This utility model simple in construction, it is easy to safeguarding, purification efficiency is higher, can solve the problem existing for desulfurizing tower to a certain extent, have certain using value.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model desulfurizing tower.
Fig. 2 is the structural representation of airflow-distribution board in Fig. 1.
In figure: 1. smoke inlet；2. slurry pool；3. airflow-distribution board；4. gas-liquid distribution ball；5. atomization sprayer；6. demister；7. tower body；8. exhanst gas outlet.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
Such as Fig. 1, a kind of desulfurizing tower being applicable to ultra-clean discharge, from bottom to top set gradually: slurry pool 2, smoke inlet 1, airflow-distribution board 3, gas-liquid distribution ball 4, atomization sprayer 5, demister 6, tower body 7, exhanst gas outlet 8.
Former cigarette is after smoke inlet 1 enters tower body 7, and flue gas rises to airflow-distribution board 3, and the through hole on airflow-distribution board 3 makes air flow method evenly, it addition, the liquid film on airflow-distribution board 3, greatly improve gas-liquid mass transfer efficiency, increase the turbulent extent of flue gas so that desulfurizing tower purification efficiency is higher.
Arranging multiple equally distributed atomizer on atomization sprayer 5, atomization sprayer 5 is connected with slurry pool 2 and carries out serum recycle simultaneously, and the serosity that atomization sprayer 5 sprays out forms liquid film on airflow-distribution board 3.
In Fig. 2, airflow-distribution board 3 is broken-line type, and its bending angle is 90 ° ~ 120 °, and the through hole on airflow-distribution board 3 is circular hole or square hole or irregular hole, and the vias rate of airflow-distribution board 3 is 60% ~ 70%, and through hole is intensive on airflow-distribution board 3 to be uniformly distributed.
Flue gas is by continuing rising after airflow-distribution board 3, the effect of gas-liquid distribution ball 4 makes serosity be improved in the concentration of tower wall, extends the gas-liquid mass transfer time at Ta Bichu simultaneously, thus decreases the SO along tower wall2Escape amount, improves the purification efficiency of desulfurizing tower.
Gas-liquid distribution ball 4 is hemispherical or ellipsoid shape, evenly distributed at Ta Bichu interval, and the flue gas after abundant gas-liquid mass transfer rises to demister 6 in tower body 7 and removes the steam of excess in flue gas.
Exhanst gas outlet 8 is located at desulfurizing tower top left hand, broken-line type design with relax flue gas muzzle velocity, reduce the pressure loss, purified after exiting flue gas reach ultra-clean discharge standard.
Above content is to combine specific embodiment further detailed description of the utility model, it is impossible to assert that of the present utility model being embodied as is confined to these explanations.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, it is also possible to make some simple deduction or replace.
