Summary of the invention
The purpose of this utility model provide a kind of simple in structure, anticorrosive construction convenient, less scaling, dust-removal and desulfurizing is effective, dedusting, the incorporate dedusting and desulfurizing tower of desulphurization plant, especially a kind of square dedusting and desulfurizing tower that is used for the boiler smoke wet dedusting desulfurization.
The utility model structure comprises: tower body, smoke inlet, forward jetter, packing layer, reverse spray thrower, demister, exhanst gas outlet, soot blower, chassis and inspection manhole constitute.
Forward jetter is located at the tower body bottom, is made up of the cleaning solution person in charge, palisade distributor pipe and several nozzles, and nozzle opening upwards.Flue gas is introduced in the tower by tower body bottom smoke inlet.Forward jetter can be arranged on the smoke inlet under or at same horizontal level.Packing layer is located at the middle part of tower body, is made up of supportive grid, filler (can be various corrosion-resistant fillings, as nut, organic filler, metal packing etc.), platen and fixture.Reverse absorption liquid spray thrower is located in the tower body, top, and the position is made up of the absorption liquid person in charge, palisade distributor pipe and several nozzles respectively on packing layer, and nozzle opening is downward, and reverse absorption liquid spray thrower can be provided with 1～6 grade, is preferably three grades.When adopting multistage reverse spray thrower, adopted respectively from top to bottom and can produce the nozzle that fogdrop diameter varies in size, mist droplet particle size diminishes gradually from top to bottom.Soot blower is located at the bottom of the tower, is made up of the cleaning solution person in charge and several nozzles.Leakage fluid dram is arranged on tower bottom, and exhanst gas outlet is arranged on top of tower, and demister is arranged on before the exhanst gas outlet, and inspection manhole is arranged on the tower bottom.
Tower body adopts composite construction, is made of framework, panel, anticorrosion paste layer and stiffener assembly, and shape can be circular, square or other suitable shape.
The utility model is according to containing the characteristics of sulfur dioxide flue gas, by purified treatment targetedly step by step, can obtain desirable clarifying smoke rate and desulfurization degree.The utility model apparatus structure is simple, and floor space is little, and is reliable, and desulfurization, dust removal efficiency height can be used for various types of flue gas desulfurization and dedusting purified treatment.
Description of drawings
Fig. 1 is a kind of dedusting and desulfurizing tower assembling of the utility model schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, as shown in Figure 1, this tower comprises tower body 1, smoke inlet 13, forward jetter 9, nut packing layer 7, three grades of reverse spray throwers 4,5,6, demister 3, exhanst gas outlet 2, soot blower 12, chassis 11, liquid outlet 10 and inspection manholes 8.
During work, flue gas to be clean is entered in the tower by smoke inlet 13, establishes a jetter 9 forward at the bottom of tower, this jetter by cleaning solution be responsible for, palisade distributor pipe and several nozzles form; This jetter evenly cleaning solution of ejection carries out hydro-peening to the flue gas of flowing through herein, and at the bottom of wherein the flue dust of larger particles dropped down onto tower together with cleaning solution, flue gas was realized pre-dedusting.
In tower, the bottom is provided with nut packing layer 7, this packing layer is made up of supportive grid, nut, obstruct grid and fixture; Than the flue dust of small particle diameter in this gathering, adhere to.Nut is fluidized when flue gas is blown over from bottom to top, and like this, packing layer can not fall because of fouling produces big pressure.Simultaneously, because of spray thrower (III) 6 has the effect of flushing packing layer, can will assemble, dash at the bottom of the tower attached to the flue dust on the nut.Flue gas is finished dust removal process herein.Dust removal efficiency reaches 97% after testing.
In tower, top is provided with three grades of reverse absorption liquid spray throwers 4,5,6, the absorption liquid spray thrower respectively by absorption liquid be responsible for, palisade distributor pipe and several nozzles form.Three grades of reverse spray throwers 4,5,6 have adopted respectively from top to bottom and can produce the nozzle that fogdrop diameter varies in size, and the mist droplet particle size that spray thrower (I) 4 produces is bigger, have the double action of the less droplet in distribution absorption liquid and the capture rising; The mist droplet particle size that spray thrower (II) 5 produces is less, thereby it is long-pending than large contact surface that absorption liquid and flue gas are had as much as possible, to improve desulfuration efficiency; Spray thrower (III) 6 has the effect of flushing packing layer and distribution absorption liquid.After flue gas is flowed through herein, finish the dust-removal and desulfurizing process, realized the purpose that purifies.According to the difference of the adsorbent of operating condition and use, desulfurization degree can reach 60%～90%, even more than.
This tower is provided with demister 3 at cat head exhanst gas outlet 2 places, is made up of lineup's font flap, and demister 3 adopts and hangs, the mode of a combination, and angled with flue gas flow direction, at the bottom of the droplet that become trapped in flow to tower in assembly on the demister and along Ta Bi.Flue gas after being purified is discharged outside the tower by the exhanst gas outlet 2 that is located on the top of tower sidewall.Establish a soot blower 12 at the bottom of tower, this soot blower is responsible for by cleaning solution and several nozzles are formed, and its effect is that the flue dust that will be deposited at the bottom of the tower dashes to the exit, and with cleaning solution, absorption liquid outside liquid phase outlet 10 outflow towers.Forward the nozzle quantity of spray thrower and three layers of anti-phase spray thrower can be determined according to unit scale and purification batch mark etc. are concrete.
