Description

Pneumatic emulsification treatment device

Technical Field

The utility model belongs to the technical field of flue gas purification equipment technique and specifically relates to utilize pneumatic emulsification principle to carry out the processing apparatus who purifies to the flue gas of equipment such as industrial kiln, boiler.

Background

The wet flue gas desulfurization is the most widely used desulfurization technology, which almost accounts for 85% of the total capacity of the global desulfurization installed machine, the specific realization methods of the wet flue gas desulfurization include more than 200, most of the wet flue gas desulfurization methods can not be separated from nozzles, such as empty tower spray, venturi, rotational flow plate tower, bubble tower, turbulent ball tower, porous plate tower, water film tower and the like, and spray liquid distribution can not be separated from the nozzles.

In the last 20 years, more than 1000 pneumatic emulsification desulfurizing towers are put into industrial operation, and the absorption tower has simple and compact structure due to high desulfurizing efficiency, low operating cost and wide application in the non-ferrous metal smelting industry, the highest desulfurizing efficiency reaches 99.99 percent, the operating power consumption is only 20 percent of that of other methods, and the performance is very stable.

In 2008, the double-cyclone pneumatic emulsification desulfurization tower is successfully researched and developed, and is gradually applied to industries other than nonferrous smelting from 2010. In 2016, the sintered gas is put into commercial use and is used for meeting the conditions of unstable gas quantity and large fluctuation change of the sintered gas in ferrous metallurgy. At present, in hundreds of thousands of boilers and tens of thousands of pellet sintering production equipment in China, more than 400 furnaces are provided with pneumatic emulsification desulfurizing towers.

The multi-cyclone pneumatic emulsification desulfurization tower has high desulfurization efficiency, and has the advantages of smaller scale of the whole system equipment, low operating cost and the like, and has market competitiveness compared with wet methods such as spraying and the like, semi-dry methods such as a circulating fluidized bed and the like, and dry methods such as activated carbon and the like. However, in operation, the following may occur:

firstly, the resistance of the desulfurizing tower is large, when the flue gas to be treated is high-sulfur (tens of thousands of milligrams), the liquid-gas ratio design value is large, the resistance of a single tower is lower than a certain value, generally a single-tower double-cyclone is adopted in the original pneumatic emulsifying desulfurizing tower, and when the high-sulfur flue gas is treated, a multi-tower series connection mode is adopted, so that the standard discharge of an outlet is ensured. Even so, the tower resistance generated by processing the ultra-high sulfur flue gas is very high, and 70000mg/m of ultra-high sulfur flue gas is processed in the design³In the engineering practice of sulfur dioxide flue gas, 100mg/m of sulfur dioxide at the outlet is achieved³When the following requirements are met (the desulfurization rate is 99.86%), the series resistance of the double towers of the actual double cyclone tower reaches 14000pa, which is far higher than 8000pa resistance calculated by theory, and the total resistance is totalThe higher the body resistance is, the larger the work done by the flue gas to overcome the tower resistance is, the higher the performance requirement of the fan to be equipped is, the larger the rated power and the actual operating power of the matched motor under the same flue gas condition can be, and the higher the energy consumption of the whole production line is. Although the high efficiency of the pneumatic emulsification technology is verified, the actual production has large energy loss, and when the capacity of the fan is insufficient, the production is even affected, the actual production operation difficulty is high, and the pneumatic emulsification technology (pneumatic emulsification desulfurizing tower) still has a large improvement space.

Secondly, the resistance of the desulfurizing tower is uncontrollable. The pneumatic emulsification technology is widely used in the field of kiln waste gas treatment in the industries of ferrous metallurgy, nonferrous smelting and the like, in the field of nonferrous smelting and renewable resources, the kiln has high content of harmful substances such as sulfur and the like in kiln ingredients, the kiln load change is large, and by using an oxygen-enriched side-blown furnace in the secondary lead industry such as the factory area of environmental protection science and technology limited company of Zhongqing in Shandong, the maximum kiln sulfur dioxide discharge amount reaches 70000mg/m³Average sulfur dioxide is 42000mg/m³The feeding time is 6 hours, and the period is from 7000mg/m³Sulfur dioxide concentration to 70000mg/m³Only 15 minutes are needed, the fresh circulating liquid amount is instantly increased by multiple times in the process, the thickness of an emulsion layer is correspondingly increased, the resistance is correspondingly increased, and the highest tower resistance reaches 13000 pa.

Thirdly, most of the sulfur dioxide in the kiln generating high-sulfur flue gas is unstable, and the fluctuation from thousands of milligrams to tens of thousands of milligrams is very large. The desulfurization system can be actually regarded as a chemical production line for preparing desulfurization byproducts, and when the working condition is unstable, the production parameters are difficult to control, and the preparation of the desulfurization byproducts is unstable.

The method is characterized in that after harmful substances in the flue gas are absorbed by the slurry of the emulsion layer formed by all layers of cyclones in a cyclone cylinder, the main process parameters (pH value and density) of the method are different due to different concentrations of the harmful substances in the flue gas, the absorption efficiency and the absorption effect of all layers are different, and the subsequent treatment and control are also different. When the concentration parameter of pollutants in the treated flue gas fluctuates greatly, the slurry feeding amount of each layer of the emulsion layer of the desulfurizing tower is increased and reduced, but the absorption efficiency and effect of each layer cannot be accurately known, so that the reaction time of the slurry absorbing harmful substances is not stable, and the process control time is changed.

Therefore, all the equipment scale sizes and types are designed according to the maximum design value, sometimes the design margin is increased, the overall scale of the project is determined from the initial design, and the investment does not reach the most economic state; meanwhile, wet desulphurization has certain requirements on the quality of the desulfurizer, for example, the required mesh number of limestone powder is more than 300 meshes, the CaO content is more than 52%, the finer the limestone particles are, the better the desulphurization effect and the desulfurization gypsum effect are, but the higher the quality of the limestone powder is, the higher the price is, equipment with certain requirements needs to be invested even if the limestone powder is ground by self, and the investment and energy consumption do not reach the optimal state. If the system is a single-layer cyclone pneumatic emulsification desulfurization tower with a plurality of towers connected in series, the problems can be solved, but a plurality of desulfurization towers are needed, the cost is high, the occupied area is large, and unnecessary waste is caused.

Fourthly, the material that present pneumatic emulsification desulfurizing tower, most use is 316L stainless steel, when meetting the flue gas fluorine-containing of chemical industry flue gas, the high flue gas of chloride ion also can use plastics materials such as PP to make. The desulfurizing tower made of the materials needs to be manufactured and installed, and due to transportation reasons, when a large project with hundreds of thousands to millions of flue gas volumes is processed, the desulfurizing tower cannot be manufactured in a factory, most of the desulfurizing towers need to send materials to a project site for field manufacturing and installation, the main processes of field manufacturing and installation are a large amount of welding work, the shortest construction period of a project also needs about 2-3 months, and the manufacturing and installation of the desulfurizing tower needs 1-2 months. Due to the open-air operation, weather, environment and other reasons, the quality and the construction period of the manufacturing of the desulfurizing tower are affected, and the quality and the speed are not comparable to those of the manufacturing of a processing plant.

Specifically, the pneumatic emulsification and desulfurization tower is mainly structurally (from bottom to top) divided into an air-homogenizing section, a filtering element group section and a demisting section, the air-homogenizing section and the demisting section of the conventional pneumatic emulsification and purification tower are made of stainless steel wall plates, the whole plate is cut, and after the wall plates are welded, the outer wall is welded and provided with a carbon steel reinforcing rib to ensure the strength; the filter element (cyclone cylinder) is manufactured by prefabricating the cyclone firstly and then installing/welding/connecting the cyclone into a tubular container with a hollow inner part, so that when the filter element group is required to be large-caliber in a meeting project, the filter element group is inconvenient to be manufactured and molded in a factory and then transported to a field for welding and installation (ultra-wide and ultra-high in steam transportation); all materials are generally transported to the site and then processed on site. Since the interior of the filter element is substantially empty except for the cyclone, the economy of the factory-fabricated shaped cyclone cartridge at the shipping site is very poor. A large amount of field welding leads the project period to be long.

If the components of the desulfurization tower cannot be fabricated in a processing plant and must be fabricated on site, the following problems may occur:

1. quality control problem compares mill's processing preparation, because cost and place reason, on-the-spot preparation has the factor that the several influences system ampere quality:

(1) the sites of non-ferrous smelting and ferrous metallurgy factories are limited, and the manufacture is difficult to completely spread;

(2) the blanking, welding, installation and derusting levels of the employed manufacturers cannot be completely controlled;

(3) according to the construction period, possible construction quality management regulations cannot be well implemented, for example, when special welding rods are used, the welding rods need to be insulated, welding slag needs to be removed completely, some parts need to be pickled, and 3-4 paths of paint need to be brushed on part of the platform stairs for protection, and the like are not performed seriously;

(4) the field environment is worse than that of a factory, and the field factory areas of ferrous metallurgy, nonferrous smelting and the like have large dust and dust, so that the cleaning of materials can not be ensured in place during manufacturing. The subsequent process treatment leads to unstable quality of the finished product.

2. Safety problems, according to local environmental protection requirements, environmental protection facilities (including a chimney) are not less than tens of meters, operation difficulty such as high-altitude hoisting, welding and the like is large, and safety accidents are easy to occur if management is not in place; if various media exist on the site, and leakage occurs, safety accidents are easy to occur.

3. The construction period problem, a general desulfurization project, as for a pneumatic emulsification desulfurization system, is 2-4 months, and comprises a design period of 20-30 days, a civil engineering construction period of 20-30 days, and an equipment manufacturing and installation period of 30-50 days; and for the spray desulfurization system, the total construction period is 6 months, the equipment manufacturing and installation period needs more than 60 days (including an anticorrosion process in the manufacturing process of the desulfurization tower), and no matter which mode, a large amount of construction time is needed, so that the planned production of an owner is greatly influenced.

Fifthly, the 316L stainless steel is the mainstream material for manufacturing the pneumatic emulsification desulfurizing tower, but because the desulfurizing tower is designed to be in a welding connection mode originally, other high-performance materials which can not be welded can not be used according to the specific working condition of the flue gas, such as electroplating composite materials and ceramics, and the like, the pneumatic emulsification desulfurizing tower can not adopt the electroplating composite materials and the ceramics or other materials which are not suitable or can not be welded, so that the popularization of the pneumatic emulsification technology is limited, and the special material which can effectively reduce the cost can not be used according to the actual working condition of the flue gas.

Detailed Description

In order to make the technical field better understand the solution of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings and the detailed description.

In this document, terms such as "front, rear, inside, and outside" are established based on positional relationships shown in the drawings, and the corresponding positional relationships may vary depending on the drawings, and therefore, they are not to be construed as absolutely limiting the scope of protection; moreover, relational terms such as "first" and "second," and the like, may be used solely to distinguish one element from another element having the same name, without necessarily requiring or implying any actual such relationship or order between such elements.

A typical pneumatic emulsification principle in which a purification element operates is as follows: in a circular tubular device of a purification element, accelerated flue gas to be treated enters a container from the lower end of the container at a certain angle to form a rotating and ascending turbulent flow, the turbulent flow collides with an unstable solution flowing down from the upper end of the container, the solution flowing down is cut by the high-speed rotary cutting of the flue gas, the gas and the liquid are fully mixed, a section of dynamically stable emulsion layer is formed under the matching of proper parameters, the emulsion layer is gradually thickened in the emulsification process, and the ascending pneumatic supporting force and the gravity of the emulsion reach balance. Along with the flow of the flue gas, part of the emulsion is taken away, the previously formed emulsion is replaced by the newly formed emulsion, and harmful substances carried by the flue gas in the emulsion layer are contacted with fine liquid particles in the emulsion so as to be absorbed.

The pneumatic emulsification and purification device is generally provided with a plurality of purification elements, each purification element is internally provided with a cyclone, and solution enters the purification elements from the upper part of each cyclone; fresh solution is also supplied with simultaneously to lower floor's swirler top, the upper emulsion mixes with fresh solution, the flue gas forms the emulsion layer with mixed liquid after accelerating through lower floor's swirler, this layer emulsion volume is the total of this layer fresh solution and upper strata whereabouts emulsion, aerodynamic force is directly proportional with the square of flue gas velocity of flow, the flue gas velocity of flow that the lower floor rotation is accelerated is faster, just can provide bigger pneumatic power of holding in the palm that makes progress, reach the balance with the gravity of solution, and, at the in-process of the continuous whereabouts of thick liquid, also can correspondingly cause the improvement of filter element internal resistance. Therefore, the resistance of the emulsion layer with a thicker lower layer is larger than the theoretical value of the emulsion layer formed by the single-layer cyclone, so that the actual tower resistance of the multi-cyclone pneumatic emulsification desulfurization tower is larger. When the amount of flue gas and the content of pollutants in the flue gas are increased, the solution supply amount in the tower is correspondingly increased, the resistance in the tower is inevitably increased by times, and the performance of the pneumatic emulsification desulfurization tower cannot be further improved.

In addition, the utility model discloses the people still discovers through the research, thick liquid absorption efficiency after the pollutant reduces or has lost the reabsorption ability once more in the upper strata absorption flue gas, mix the back with the thick liquid that the lower floor was supplied with, further cause emulsion layer absorption efficiency to reduce, make lower floor's emulsion layer work efficiency can't reach the optimum condition, can only give the pollutant in the thick liquid volume desorption flue gas through the increase, and increase and to make the interior bulk resistance of tower rise after giving the thick liquid volume, it further increases the system resistance along with the practice is passed to return in the use, lead to the unable normal production of kiln.

Therefore, single-stage pneumatic emulsification desulfurization (filtration) tower sets up the purification element more than two-layer at least, and the system resistance that otherwise causes is several times of theoretical value, when handling the flue gas that pollutant content is high, generally adopts the form of multistage tower series connection, and equipment manufacturing cost is far above the system that pollutant content is low under the same flue gas volume condition, and moreover, pipeline bending between the multistage series connection tower, desulfurizing tower defogging section all can increase the tower and hinder.
