Description
Technical field
The utility model relates to a kind of desulfuration absorbing tower, particularly, relates in particular to a kind of absorption tower that is used for the wet process of FGD of thermoelectric enterprise.
Background technology
As everyone knows, problem of environmental pollution has been subjected to the extensive concern of various circles of society, solves problem of environmental pollution and has arrived instant stage to a certain extent.
Wherein, for China part city, air pollution is the most important thing in the problem of environmental pollution.Tracing it to its cause, is because the emission of automobile wastes amount increases year by year on the one hand, is because the toxic emission problem of heavy industry on the other hand.
In fact, most enterprises have given enough attention on the toxic emission problem, but because China is shorter than its technical development history of western developed country aspect the control environmental pollution, equipment is also comparatively backward, and this is that factor is that economic development with the high speed of China present stage is incompatible.
Particularly, for the most of thermoelectric enterprise of China, it adopts wet process of FGD equipment to carry out carrying out desulfurization for flue gas usually and handles, and wherein, the absorption tower is the nucleus equipment of wet process of FGD equipment.Operational circumstances such as liquid level, spray, demist are that some instruments, instrument etc. by being provided with on tower carry out centralized Control in the wet process of FGD nucleus equipment absorption tower generally speaking, can't real observation in the tower situation.Yet when carrying out work on described absorption tower, owing to have foam in slurry surface, the height of this foam can't be measured by liquid level gauge.
Owing to have the problems referred to above, so can cause following result.For example foam overflow inlet flue duct and entered booster fan, thereby booster fan is broken or cause heavy corrosion, serious can so that blower fan scrap; And, because a large amount of existence of foam, also can't observe inner case when the operation, so usually wait until and learn just when eroding to tower wall and spillage that the tower inside liner comes off for spraying layer and demister.
Under the situation that above-mentioned fault takes place, not only can cause economic loss, also can cause power plant to interrupt its production work.In addition, also can make flue gas desulfurization work to carry out smoothly.Even some enterprise makes air be subjected to severe contamination for guaranteeing that electrical production directly enters atmosphere with flue gas.
Therefore, be necessary to design a kind of new desulfuration absorbing tower in fact, to address the above problem.
The utility model content
The purpose of this utility model is to provide a kind of desulfuration absorbing tower that can directly observe the operation and the liquid level of slurries in the tower.
For achieving the above object, desulfuration absorbing tower of the present utility model comprises the absorption tower body, be located at the former smoke inlet of this body middle and lower part, absorption tower, be arranged on the slurries spraying layer of former smoke inlet top, body middle and upper part, absorption tower, be located at the demister of this spraying layer top, be arranged in the clean exhanst gas outlet of described absorption tower bodies top and connect and is connected at least one finder of setting with part more than the routine work liquid level of described absorption tower body.
According to one side of the present utility model, described finder is located at the routine work liquid level between the former smoke inlet lowest part.
According on the other hand of the present utility model, described finder is corresponding to the height setting of described slurry face spraying layer.
According to another aspect of the present utility model, described finder is corresponding to the height setting of described demister.
According to other aspects of the present utility model, described finder comprises that an end runs through the nipple that is connected with the absorption tower body, be fixed to the inner flange of the other end of this short tube, with the outward flange that this inner flange is used, the fixture that is folded in the transparent window between described inner flange and the outward flange and described inside and outside flange is fixedlyed connected with transparent window.
Preferably, between described inside and outside flange, seal is set.
Preferably, in described connection short tube inside anticorrosive coat is set preferably.
By adopting above technical scheme, not only can observe directly the operation and the level condition of the inner slurries in absorption tower, the spray effect of slurries and remove fog effect for example, and its finder can also be as liquid level gauge use on the spot, even the pressure reduction liquid level gauge goes wrong, also can directly observe liquid level,, thereby avoid occurring above-mentioned major accident with timely adjustment and control slurries liquid level by utilizing finder.Furthermore, not only can effectively transform for the absorption tower, can also effectively avoid economic loss simultaneously, and ensure carrying out smoothly of flue gas sulphur removal, thereby reduce pollution air with lower cost.
Description of drawings
Below, will be further described in detail specific embodiments of the present utility model in conjunction with the accompanying drawings, wherein:
Fig. 1 is the structural representation of desulfuration absorbing tower of the present utility model;
Fig. 2 is the cutaway view of the finder of desulfuration absorbing tower of the present utility model.
The specific embodiment
See also Fig. 1, desulfuration absorbing tower 1 of the present utility model is used for the wet process of FGD of thermoelectric enterprise, comprising absorption tower body 10, be located at the former smoke inlet 12 of these absorption tower body 10 middle and lower parts, be arranged on the slurries spraying layer 14 of absorption tower body 10 middle and upper parts, be located at the demister 16 of these slurries spraying layer 14 tops, be arranged in the clean exhanst gas outlet 18 at body 10 tops, described absorption tower and respectively with tower in operating fluid level (lime stone, gypsum slurries), slurries spraying layer 14 and the demister 16 corresponding finders of arranging 19.
For the utility model, its improvements are mainly at its finder of setting up 19, and for other parts, desulfuration absorbing tower structure basic and in the past is identical, so in the description of this omission to this same section, and emphasis is described the structure of its finder 19, and it combines and the function of this finder with absorption tower body 10.
