Abstract
The invention relates to a double-effect parallel flow wet-type seawater desulfurization tower which comprises a tower body, tower plates, a tower kettle, a water pump, a fan, a tower separator and a liquid distributor. Each three-dimensional hydraulic cyclone tower plate is arranged in a double-effect tower; the purified sulfur-containing gas enters from the single-effect top of the desulfurization tower, the sulfur-containing gas on each layer of tower plates is contacted with a scrubbing solution, sulfur dioxide is absorbed by the scrubbing solution, the absorbed sulfur-containing gas enters a double-effect top of the tower and is contacted with the scrubbing solution for scrubbing, and the full washing and absorbing effects are achieved. The mounting distance between the two adjacent tower plates in each effect is 300mm, the mounting number is three, and the blade torsion angles of the tower plates are 60 degrees. The liquid distributor is arranged at a position of 100mm above each effect, and the shape of the liquid distributor is a shower nozzle. The desulphurization efficiency is 96-99 percent, the pressure drop is 110-440Pa, gas and liquid flow in parallel in the same direction, the air velocity in an empty tower is 6-11m/s, and a flooding phenomenon is avoided. Compared with a gas-liquid countercurrent desulfurization tower, the double-effect parallel flow wet-type seawater desulfurization tower disclosed by the invention has the advantages that the diameter of the tower body is reduced by 40-70 percent, and the height is reduced by 35-65 percent.
Description
Technical field
The present invention relates to a kind of flue gas desulfurization technique, particularly a kind of industry contains the economic benefits and social benefits of fume gases and flows wet type seawater desulfurization tower, belongs to desulphurization plant washing field.
Background technology
Often need in fields such as chemical industry, pharmacy, food, exhaust-gas treatment, environmental protection to carry out purified treatment to containing fume gases.The flue dust that China's industry and life cellar for storing things stove discharge every year and industrial dust are approximately 3,200 ten thousand tons, and wherein flue dust accounts for over half.And in flue dust with sulfur dioxide and particle diameter the grit between 0.1-10 μm for major pollutants.Sulfur dioxide forms acid rain, the arch-criminal of acid mist.So, develop the key issue that efficient, economic Novel desulfurizing dust removing technology is this field.Now widely used sulfur method has wet desulphurization, dry desulfurization and semi-dry desulphurization.Wet desulphurization mainly contains limestone/lime-gypsum, ammonia stripping desulfurization and seawer washing desulfurization etc.Tower wet desulphurization tower often adopts the mode of gas-liquid counter current, can fill in tower and also can not fill column plate, desulfurized effect still can, but because gas-liquid two-phase adverse current passes through tower body, in tower, gas speed is restricted, easily there is Concerning Flooding Phenomenon time larger in gas speed, and the tower body diameter needed under certain tolerance and highly all larger.
The present invention is exactly the deficiency that will overcome Counter-current wet desulfur technology, provides a kind of economic benefits and social benefits and flows wet type seawater desulfurization tower, utilizes seawater for cleaning solution, reaches that desulfurized effect is good, SR is little, without the little object of liquid flooding tower body size.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of economic benefits and social benefits and flow wet type seawater desulfurization tower, reaches that desulfurized effect is good, SR is little, without the little object of liquid flooding tower body size.
In wet type desulfurizing operating process, need the sulfur dioxide in flue gas to absorb with high efficiency of trying one's best, to ensure that flue gas reaches discharge standard.The present invention is in cylindrical-shaped tower, three-dimensional rotary fluid-type tower plate is installed, the rear sulfurous gas of purification is imitated top from desulfurizing tower one and is entered, on every layer of column plate, sulfurous gas contacts with cleaning solution, sulfur dioxide is absorbed by cleaning solution, the rear sulfurous gas of absorption enters two effects from tower top and again contacts with cleaning solution, washs, and has reached the effect of abundant washing, absorption.
In order to solve the problem, the present invention is achieved through technology:
The rear sulfurous gas of purification is imitated top from desulfurizing tower one and is entered, in every layer of three-dimensional rotary fluid-type tower plate, sulfurous gas contacts with cleaning solution, sulfur dioxide is absorbed by cleaning solution, the rear sulfurous gas of absorption enters two effects from tower top and again contacts with cleaning solution, washs, reached the effect of abundant washing, absorption, after last desulfurization, gas is discharged from exhaust outlet.
Often in effect, adjacent two column plate installing spaces are 300mm, and installing quantity is 3 pieces, and column plate blade twist angle is 60 °.
Often effect top 100mm installs liquid distribution trough, and shape is shower nozzle.
Have employed technique scheme, the invention has the beneficial effects as follows:
Economic benefits and social benefits of the present invention also flow wet type seawater desulfurization tower, desulfuration efficiency 96% ~ 99%, and pressure drop is 110 ~ 440Pa, gas-liquid is concurrent flow in the same way, empty tower gas velocity 6 ~ 11m/s, occurs, compared with gas-liquid counter current desulfurizing tower without Concerning Flooding Phenomenon, tower body diameter reduces 40% ~ 70%, height reduction 35% ~ 65%, can save a large amount of material making desulfurizing tower, slurry recycles, need supplement fresh water amount less, availability is higher.
Therefore, the present invention, compared with existing desulfurizing tower, has outstanding advantage and is: (1) is without Concerning Flooding Phenomenon; (2) desulfuration efficiency is high; (3) installation cost, running cost are lower.
