Description

A kind of Novel flue gas pretreatment system

Technical field

The utility model belongs to industrial smoke abatement equipment technical field, and in particular to a kind of Novel flue gas pretreatment system System.

Background technology

Flue gas pretreatment system, which is widely used in steam power plant, steel mill etc., needs the industry of smoke gas treatment.Mainly it is final Discharge provides a pretreatment, reduces the operating pressure of flue gas final process equipment.The minimum discharge of national requirements flue gas at present, Original discharge numerical value can not meet discharge standard, it is necessary to which flue gas is further processed.Especially haze is tighter in recent years Weight, require more strict for the dust emission in flue gas, many local requirements soot emissions reach 5mg/Nm³.Wet electrostatic Deduster is can effectively to catch one of capital equipment of dust in flue gas, and the equipment major defect is cost of investment and operation Expense is all very high.The height of dust content has direct relation in the size and flue gas of wet cottrell specification, if into The dust content of wet cottrell is high, then needs to increase the area of its dust collecting electrode, so as to increase input cost.Many enterprises Industry is abandoned setting up wet cottrell, can only face stopping production；Also many enterprises are even mounted with wet cottrell, Because operating cost is too high, also seldom operation, performs practically no function.At present also have many production units can wet cottrell it Before set up flue gas pretreatment system, but its pretreatment system is complicated so that whole Meteorological, goes up not down.Existing flue gas Pretreatment system mainly has tower body, spraying layer, and supporting water pump and circulatory pool form, and the effect for reducing Dust Capacity is brighter It is aobvious.But prior art causes substantial amounts of resource wave to be continuously increased tower body height and spray flux to realize pretreating effect Take.In addition, substantial amounts of spray to carry substantial amounts of water smoke in flue gas, wet electric operating load may be increased.

Utility model content

The technical problems to be solved in the utility model is：Overcome the deficiencies in the prior art, there is provided a kind of device structure is simple, Occupy little space, the Novel flue gas pretreatment system that efficiency of dust collection is high, input is low with operating cost.

Technical scheme is used by the utility model solves its technical problem：A kind of Novel flue gas pretreatment system, its It is characterised by：Including a cylinder, a spray equipment is set in the cylinder；The spray equipment includes：Laterally laying support Beam, the support beam both ends are fixed on an arm；In the support beam, some spray pipings, the spray are longitudinally equipped with The tube wall top in shower pipe road offers several nozzles；The top of the spray piping is covered with arc plate.

Preferably, the arc plate radius is more than the radius of the spray piping.

Preferably, in the cylinder, it is provided with one layer of spray equipment described above.

Preferably, the arc plate in adjacent two layers is staggered.

Preferably, the spray equipment is horizontal, be arranged in parallel.

Preferably, between the support beam, between the spray piping, between the arc plate, impartial spacing is regularly arranged.

Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, occupies little space, Input cost is low.It can reduce in flue gas 30% dust content, reduce the dust collecting electrode area of wet cottrell, significantly Reduce the input and operating cost of wet cottrell；The utility model can also play uniform effect to flue gas, can generation For original gas guide board.

Brief description of the drawings

Fig. 1 is the structural representation of the utility model embodiment；

Fig. 2 is the enlarged drawing at A in Fig. 1.

In figure mark for：

1st, cylinder；2nd, support beam；3rd, spray piping；4th, nozzle；5th, arc plate.

Embodiment

Embodiment below in conjunction with the accompanying drawings, the utility model is described further：

Embodiment one

As shown in Figure 1, 2, a kind of Novel flue gas pretreatment system, including cylinder 1, in cylinder 1, two layers of spray dress is set Put；Spray equipment includes, and is laterally equipped with some support beams 2, and the both ends of support beam 2 are fixed on an arm；In support beam 2 Surface, is longitudinally equipped with some spray pipings 3, and the tube wall top of spray piping 3 offers several nozzles 4；Every spray The top of pipeline 3 is covered with arc plate 5, and the radius of every arc plate 5 is all higher than the radius of spray piping 3, to ensure in arc plate 5 Surface has 110% flushing coverage rate.

Arc plate in each layer be arranged in parallel, and the arc plate 5 in upper and lower two layers is staggered；Between each bar support beam 2, each bar It is equidistantly regularly arranged between spray piping 3, between each arc plate 5.

The course of work of the present utility model is as follows：

As shown in Figure 1, 2, in the entry position of wet cottrell, gas approach and wet cottrell are utilized Connection space or the border region using desulfurizing tower and wet cottrell, the utility model is installed；Arc plate 5 is arranged on In support beam 2, then nozzle 4 is set on the arranged beneath spray piping 3 of arc plate 5, spray piping 3, ensures the inner surface of arc plate 5 It is provided with 110% or more flushing coverage rate.Flue gas is flowed out by desulfurizing tower, is entered first before into wet cottrell Enter arc plate 5, the arc plate 5 that flue gas passes through in lower floor is turned back away, subsequently into the arc plate 5 in upper strata, by the flue gas of pretreatment Wet cottrell body is directly entered, is further processed.So, before flue gas enters wet cottrell, Go out to be additionally arranged two layers of arc plate 5 and its auxiliary equipment in gas approach, flue gas is pre-processed.The inwall of arc plate 5 is needed into Row periodic flushing, avoid internal deposition dust excessive, be again introduced into flue gas, cause secondary pollution.

It is described above, only it is preferred embodiment of the present utility model, is not that other forms are made to the utility model Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent The equivalent embodiment of change.But it is every without departing from the content of the technical scheme of the utility model, it is real according to technology of the present utility model Any simple modification, equivalent variations and the remodeling that confrontation above example is made, still fall within the guarantor of technical solutions of the utility model Protect scope.
