There is rhone, water is directly flowed down from the rhone for being located at 3 lower of deflector along shell wallboard, so that it may avoid enter into lower layer
Electric field region 2 avoids lower layer electric field region 2 that short circuit phenomenon occurs.
Deflector 3 shown in figure not only tilts in the longitudinal direction, but also is divided into symmetrical two parts, this two parts exists
Also be in tilted layout on left and right directions, in the middle part of height be lower than the height on both sides, form deflector shape intermediate high, that both sides are low
Formula.
In the process of running, the steam in the remover of conductive glass steel tube 51 of lower layer electric field region 2 is in off state, upper layer electric field region
Steam is open state in 1 remover of conductive glass steel tube 51, and flue gas is when by lower layer electric field region 2, due to leading for lower layer electric field region 2
There is not steam in electric glass reinforced plastic pipe 51, the vapor in flue gas, which encounters cold remover of conductive glass steel tube 51, can be condensed into water；Work as heat
When flue gas is by upper layer electric field region 1, due to being connected with steam in the remover of conductive glass steel tube 51 of upper layer electric field region 1, flue gas is by conductive
51 temperature of glass reinforced plastic pipe increases, to avoid the occurrence of " white haze " phenomenon.
In addition, only need to periodically be sprayed, not needed to remover of conductive glass steel tube 51 according to system operation situation when using
Long-term water spray and overflow water.
When upper layer electric field region 1 is sprayed, the remover of conductive glass steel tube 51 of lower layer electric field region 2 is connected with steam, and flue gas passes through
It is heated when the remover of conductive glass steel tube 51 of lower layer electric field region 2, and the obstructed steam of remover of conductive glass steel tube 51 of upper layer electric field region 1, cigarette
Gas by upper layer electric field region 1 remover of conductive glass steel tube 51 when, condensation can be played to flue gas.Due in lower layer electric field region 2
Remover of conductive glass steel tube 51 is longer than upper layer electric field region 1, and the contact area of flue gas and remover of conductive glass steel tube 51 is bigger, therefore flue gas
Temperature rise effect is bigger than flue gas condensing effect, and flue gas is overall or heats up.
When lower layer electric field region 2 is sprayed, the obstructed steam of remover of conductive glass steel tube 51 of lower layer electric field region 2, flue gas passes through
When the remover of conductive glass steel tube 51 of lower layer electric field region 2, condensation can be played to flue gas, and the electroconductive frp of upper layer electric field region 1
Pipe 51 leads to steam, and flue gas is thus sustainable to heat up to flue gas by being heated when the electric field region 1 of upper layer, and then flue gas can
It is directly arranged by flue to chimney, is also effectively solved the problems, such as " white haze ", and be conducive to the lifting of smoke height.
The remover of conductive glass steel tube 51 of dust collecting electrode 5 is connected with steam pipework, and steam is passed through conduction by these steam pipeworks
Glass reinforced plastic pipe 51, steam can be discharged together after remover of conductive glass steel tube 51 with flue gas, or as condensed water along leading
Flowing plate outflow.
Use above-mentioned wet-esp temperature rising integrated device, it may not be necessary to condenser is added after wet electrical dust precipitator
Effect, cost of investment " except white ", which can be reached, with follow-up equipments such as MGGH to substantially reduce；It can effectively solve wet-esp
Flue-gas temperature is low after device and subsequent flue, chimney low-temperature corrosion problem, and is conducive to the lifting of smoke height.
Above-described embodiment is only the preferred embodiment of the utility model, is specifically not limited thereto, on this basis can basis
Actual needs is made having and targetedly be adjusted, to obtain different embodiments.For example, the shutter of upper layer deflector 32
In inverted " u "-shaped；Alternatively, the flue gas opening on lower layer's deflector 31 can be continuously, it is also possible to intermittent, etc..Due to
Mode in the cards is more, just no longer illustrates one by one here.
Wet-esp temperature rising integrated device provided by the utility model is described in detail above.Herein
Specific case is applied to be expounded the principles of the present invention and embodiment, the explanation of above example is only intended to
Help understands the core concept of the utility model.It should be pointed out that for those skilled in the art, not taking off
Under the premise of from the utility model principle, several improvements and modifications can be made to this utility model, these improvement and modification
It also falls into the protection scope of the utility model claims.
