The smoke deacidifying device of the rotary kiln is applicable to deacidifying treatment on smoke generated by the rotary kiln.
Description
Technical field
The utility model relates to a kind of flue gas processing device, especially relates to a kind of deacidifying flue gas device of rotary kiln.
Background technology
Rotary kiln is widely used in the industry such as metallurgy, chemical industry, building refractory material, environmental sanitation.It in use can produce a large amount of flue gases, and the flue gas of its generation need to just can enter atmosphere after the processing such as depickling, dedusting reach discharge standard.
The depickling that existing rotary kiln is generally used extracting tower to carry out flue gas is processed, and sometimes because the content of acid gas producing in rotary kiln in flue gas is higher, cannot realize whole absorptions of sour gas after by an extracting tower, makes flue gas reach emission request.This kind of too high fume emission of content of acid gas can cause atmosphere pollution, forms the harm such as acid rain, acid mist.In order to control pollution, the harm of control acid rain, the flexible processing that how to realize deacidifying flue gas is very necessary.
Utility model content
The utility model has overcome shortcoming of the prior art, provides a kind of depickling mode flexibly, effectively to realize the deacidifying flue gas device of the rotary kiln of deacidifying flue gas.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of deacidifying flue gas device of rotary kiln, comprise the first extracting tower and the second extracting tower that are set up in parallel on smoke discharging pipe, on the smoke exhaust pipe of described the first extracting tower, be provided with the first valve of often opening; On the smoke-intake pipe of described the second extracting tower, be provided with the second valve of often opening; The pipeline that is provided with connection between the outlet of described the first extracting tower and the first valve, the other end of this pipeline is communicated with the import of the second extracting tower, is also provided with the 3rd normally closed valve on this pipeline.
Preferably, described the first valve adopts stainless valve.
Preferably, described the second valve adopts stainless valve.
Preferably, described the 3rd valve adopts stainless valve.
Preferably, described pipeline adopts welding to be connected with the smoke exhaust pipe of the first extracting tower and the import of the second extracting tower.
Compared with prior art, the utlity model has following advantage:
(1) the utility model, by being provided with the first valve of often opening on the smoke exhaust pipe at the first extracting tower, is provided with the second valve of often opening on the smoke-intake pipe of the second extracting tower; The pipeline that connection is set between the outlet of the first extracting tower and the first valve, the other end of this pipeline is communicated with the import of the second extracting tower, and the 3rd normally closed valve is also set on this pipeline.When content of acid gas in flue gas is higher, can close the first valve and the second valve, and open the 3rd valve, and realize the order depickling of flue gas from the first extracting tower to the second extracting tower, effectively solution is worked as the single extracting tower of acid gas in flue gas too high levels and is difficult to a depickling difficult problem up to standard.
(2) if the discharge capacity of flue gas is less in using, can close the second valve, realize the use of single extracting tower, save the energy.Depickling mode of the present utility model is flexible, can process flexibly according to the situation of flue gas, so as to reaching best deacidification effect.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The deacidifying flue gas device of rotary kiln shown in Fig. 1, comprises the first extracting tower 1 and the second extracting tower 2 that are set up in parallel on smoke discharging pipe 7, is provided with the first valve 5 of often opening on the smoke exhaust pipe 11 of described the first extracting tower 1; On the smoke-intake pipe 21 of described the second extracting tower 2, be provided with the second valve 4 of often opening; The pipeline 3 that is provided with connection between the outlet of described the first extracting tower 1 and the first valve 5, the other end of this pipeline 3 is communicated with the import of the second extracting tower 2, is also provided with the 3rd normally closed valve 6 on this pipeline 3.Described the first valve 5, the second valve 4 and the 3rd valve 6 preferably adopt stainless valve, effectively prevent the oxide etch of valve, better adapt to working environment.Described pipeline 3 adopts welding to be connected with the smoke exhaust pipe 11 of the first extracting tower 1 and the import of the second extracting tower 2, obviously also can adopt flange to connect.
When content of acid gas in flue gas is higher, can close the first valve 5 and the second valve 4, and open the 3rd valve 6, realize flue gas from the order depickling of the first extracting tower 1 to second extracting tower 2, effectively solution is worked as the single extracting tower of acid gas in flue gas too high levels and is difficult to a depickling difficult problem up to standard.And the discharge capacity of working as flue gas is less, can close the second valve 4, realize the use of single extracting tower, save the energy.Depickling mode of the present utility model is flexible, can process flexibly according to the concrete condition of flue gas, so as to reaching best deacidification effect.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
