Abstract
The utility model discloses an alkali adding device for flue gas desulfurization. The alkali adding device comprises a water reservoir for holding return water and a reaction tower for the flue gas desulfurization reaction, wherein the reaction tower is connected with the water reservoir through a water feeding device; an alkali storage can for storing the alkali liquor is arranged beside the water reservoir; an alkali discharging device is arranged at the bottom of the alkali storage can; and the alkali discharging device is directly connected with the water feeding device. In the utility model, the alkali adding device is directly connected with the water feeding device in the flue gas desulfurization process; the alkali liquor can be pumped into the reaction tower in the process of feeding water to the reaction tower, so that the alkali liquor and the water can be mixed in the water feeding device, and the alkali liquor does not need to be artificially added into the water reservoir at one time; therefore, the situations of precipitation can be avoided as the alkali liquor cannot be fully combined with the acidic material of the water in the water reservoir; meanwhile, the using amount of the alkali liquor can be effectively reduced and the invested cost for the flue gas desulfurization can be reduced.
Description
Technical field
The utility model relates to the flue gas desulfurization technique field, relates in particular to a kind of adder-subtractor that is used for flue gas desulfurization.
Background technology
The operation principle of flue gas desulfurization technique is: alkali lye is added make reactant liquor in the water and pump into reaction tower as absorbent and fully contact mixing with flue gas, alkali in sulfur in smoke and the reactant liquor and the air that blasts from the tower bottom carry out oxidation reaction and generate calcium sulfate, calcium sulfate reaches the certain saturation degree post crystallization, utilizes heavy grey pump to extract crystallization out reaction tower then and stores outward.The alkali method that adds original in whole technical process is manually directly alkali lye to be added in the entry, while is utilized artificial again or immersible pump stirs the liquid in the pond, so that alkali lye fully mixes, this alkali method that adds is not easy control and adds alkali number, to such an extent as to cause a large amount of alkali lye can not be fully and the acidic materials chemical combination in the water and produce precipitation, make alkali lye cause bigger waste, be unfavorable for saving the flue gas desulfurization cost.
The utility model content
Technical problem to be solved in the utility model provides a kind of adder-subtractor that is used for flue gas desulfurization, can avoid a large amount of alkali lye to produce precipitation effectively in cistern, helps saving the cost of flue gas desulfurization technique.
For solving the problems of the technologies described above, the technical solution of the utility model is: the adder-subtractor that is used for flue gas desulfurization, comprise the cistern of splendid attire backwater and be used for the reaction tower that flue gas desulfurization is reacted, described reaction tower connects described cistern by water-supply apparatus, the other storage alkali jar that stores alkali lye that is equipped with of described cistern, described storage alkali pot bottom is equipped with out the alkali device, describedly goes out the alkali device and directly connects described water-supply apparatus.
As optimized technical scheme, described water-supply apparatus comprises charging pump, is installed with upper hose on the described charging pump, and the end of described upper hose extend in the described cistern.
As to improvement of the technical scheme, describedly go out the alkali device and comprise alkali outlet pipe, the control valve that control alkali lye flows out is installed on the described alkali outlet pipe, described alkali outlet pipe end extend into the described upper hose that is arranged in described cistern.
Owing to adopted technique scheme, the beneficial effects of the utility model are: in flue gas desulfurization technique adder-subtractor is directly connected water-supply apparatus, on in reaction tower, pump into alkali lye in the reaction tower together in the process of water, alkali lye mixes in water-supply apparatus with water, do not need again in the disposable adding cistern that alkali lye is artificial, thereby avoided alkali lye in cistern, can not produce precipitation with the abundant chemical combination of the acidic materials in the water, reduce the use amount of alkali lye effectively, thereby helped to reduce the flue gas desulfurization input cost.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: the 1-cistern; The 2-reaction tower; The 3-upper hose; 4-storage alkali jar; The 5-alkali outlet pipe; The 6-control valve; The 7-charging pump.
The specific embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in drawings, the adder-subtractor that is used for flue gas desulfurization, comprise the cistern 1 of splendid attire clear water and be used for the reaction tower 2 that flue gas desulfurization is reacted, described reaction tower 2 connects described cistern 1 by water-supply apparatus, described water-supply apparatus comprises charging pump 7, be installed with upper hose 3 on the described charging pump 7, the end of described upper hose 3 extend in the described cistern 1, and charging pump 7 extracts needed moisture content in the flue gas desulfurization technique by upper hose 3 during work from cistern 1.
The 1 other storage alkali jar 4 that stores alkali lye that is equipped with of cistern described in the present embodiment, described storage alkali jar 4 bottoms are equipped with out the alkali device, describedly go out the alkali device and directly connect described water-supply apparatus, wherein saidly go out the alkali device and comprise alkali outlet pipe 5, the control valve 6 that control alkali lye flows out is installed on the described alkali outlet pipe 5, so that control out alkali number, described alkali outlet pipe 5 ends extend into the described upper hose 3 that is arranged in described cistern 4.
Earlier manually alkali lye is put into cistern before no longer needing flue gas desulfurization technique to carry out during present embodiment work, but flue gas desulfurization technique is when carrying out in the process opening charging pump, opening control valve can flow out alkali lye from storage alkali jar, because the end of alkali outlet pipe is to extend in the upper hose to go, charging pump is by can together being drawn into alkali lye in the reaction tower water time on the upper hose like this, thereby prevented from effectively to put into water simultaneously and can not carry out chemical combination with the acidic materials of water and produce precipitation owing to a large amount of alkali lye, when economizing on alkali number, do not need artificial yet or utilize immersible pump that the buck mixture in the cistern is stirred, thereby saved labour and technology cost effectively.
