Make, having the effect of linking well uses, while can be mutually perpendicular to by the moving direction of front stall 14 and back seat 16, Ji Ke
The two carry out simultaneously using it is fixed when, its active orientation can be defined, have the function of good lock-bit, and can be according to
Come to carry out clamping position to pipeline according to lock-bit hole 15, has the function of that limit uses well.
Example one:
Its structure mainly arranges serum recycle main pipe outside tower, and spray main pipe is circumferentially disposed, angularly equal in main pipe lower part
Cloth arranges that branch pipe, branch tube end arrange that nozzle 4, nozzle 4 are inserted into inside absorption tower.Rubber lined pipe or glass can be used in spray main pipe
Steel conduit, spray branch pipe use GRP pipe, screw conic atomizer 4 of the nozzle 4 using 120 degree of jet angles, the injection of nozzle 4
Pyramidal structure atomized drop, to guarantee that flue gas completely extends across atomized drop layer, atomized drop must cover entire absorption tower
Section；
After external desulphurization circulating spray system desulfurization technology, nozzle 4 is arranged in absorption tower tower wall orientation, spray
The injection pressure that mouth 4 exports is high, more smaller to tower center pressure, among the flue gas flow direction tower of absorption tower tower wall side, forms baffling,
Multi-layer sprinkling layer forms multilayer flue gas baffling, increases the smoke contacts time, desulfuration efficiency has been turned up.It is pressed since nozzle 4 exports
Power is high, and in the effect for adding flue gas baffling, flue gas not will form flue gas short circuit phenomenon at conventional desulfurization tower tower wall.Flue gas is in multilayer
After spraying layer, flue gas rises under the flow-disturbing effect of spraying layer, comes into full contact with atomized drop, increases desulfuration efficiency；
Technique: desulfuration recycle pump 5 is sent by being pressurized slurries extraction in desulfuration absorbing tower 1 to tower outer circulation main pipe 2, then
Enter each nozzle 4 by spray branch pipe and spray into absorption tower, the atomizing of nozzle 4 comes into full contact with drop with flue gas, absorb with
Washing realizes that the arranging rule of flue gas desulfurization Multi-layer sprinkling layer is to arrange from the top down, specifies the position and top of inlet flue gas
The relative position of spraying layer comes into full contact with the time with ensure slurries and flue gas, while can determine liquid-gas ratio according to desulfuration efficiency
Parameter, the liquid-gas ratio of slurries determine the number of plies of spraying layer, the coverage rate and covering of nozzle 4 are selected after the spray number of plies is determining after determining
Density, so that the quantity of delivery nozzle 4 is selected, meanwhile, under corresponding 4 coverage rate of nozzle and coverage density, the entrance of nozzle 4
Pressure parameter, arrangement height, the resistance of ducting of nozzle 4 etc. select the lift of circulating pump 5 as 5 selection ground of circulating pump；
In the case that absorption diameter is bigger, for the coverage effect for improving drop in the central area of absorption tower, properly increase
4 inlet pressure of nozzle reaches better effect to increase the spray distance of nozzle 4.Usually reaching desulfuration efficiency and spray covers
In the case where lid rate, the operating pressure of the inlet pressure selection 0.7bar of nozzle 4, low 5 lift of then circulating pump of 4 pressure of nozzle is small,
The operation power consumption of system is low, is beneficial to energy conservation consumption reduction nozzle 4 and is evenly distributed on the radial orientation on absorption tower, multi-tier arrangement when
It waits, 4 angle of nozzle is staggered.Make uniformly to sow liquid in entire absorption tower；
Nozzle 4 is horizontally disposed, and injection direction is radial, and spray distance, the jet angle of nozzle 4 are selected according to absorption tower tower diameter
Degree, after atomized drop ejects, comes into full contact with the flue gas to climb in absorption tower downwards with gravity, reaches ideal de-
Sulphur efficiency；
The pressure in 4 front of nozzle is big, and flue gas is blowed tower center, and the region outside 4 coverage area of nozzle then forms cigarette
Gas negative pressure, flue gas under the continuous perturbation action of Multi-layer sprinkling layer by climbing, and stirring effect is good, and gas-liquid contact time is long, takes off
Sulphur effect is good；
The selection of circulating pump 5 is mainly according to a whole set of desulfurizer entirety type selecting, while the utility model has structure simple, system
Make, is easy for installation；Enhance atomizing effect, using effect is good；Desulfuration efficiency is improved, the energy consumption of system is reduced, nozzle 4 is being inhaled
Tower visual examination is received, it is easy to maintain.
Working principle: for this kind of external desulphurization circulating spray system, first by Hospice Center's fixed board 9 and rocking bar 11 it
Between flexible connection, can allow between Hospice Center's fixed board 9 and rocking bar 11 and be rotated, thus come rotate adjust rocking bar 11 and passed
Dynamic operation, and stable use can be carried out to Hospice Center's fixed board 9 according to the fixation between Hospice Center's fixed board 9 and desulfuration absorbing tower 1,
It is matched by the shape and structure at the top of 10 left end of Hospice Center's substrate with the shape and structure of 5 bottom of circulating pump, can conveniently allow Hospice Center
Substrate 10 holds up circulating pump 5, acts the effect for arriving and being supported to circulating pump 5, enhances its stability when in use, together
When Hospice Center's base can can be driven when shaking rocking bar 11 according to the screw connection structure between rocking bar 11 and Hospice Center's substrate 10
Bottom 10 is displaced, and then to achieve the effect that change it using position, by the activity between detent block and lock-bit seat 13, i.e.,
Can interact the position for adjusting front stall 14 and back seat 16, it is convenient preferably to carry out manipulation use to it, while can front stall 14 and after
16 threaded hole that wears of middle part of seat the operation such as can connect to carry out screw thread group, have the effect of that linkage uses well, while can
It is mutually perpendicular to, can come to it when the two is carried out using fixing simultaneously by the moving direction of front stall 14 and back seat 16
Active orientation is defined, and has the function of good lock-bit, and can come to carry out pipeline clamping position, tool according to lock-bit hole 15
Play the role of limiting well and use, completes the use process of entire external desulphurization circulating spray system like this.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
