Description

Technical Field

[0001] The invention relates to the technical field of resource recovery and utilization equipment, and in particular to a pneumatic emulsification desulfurization device capable of adapting to large fluctuations in gas volume. Background Art

[0002] The existing pneumatic emulsification desulfurization tower includes an air-homing chamber, a pneumatic emulsification unit, and a demisting chamber. The air-homing chamber is a separate chamber. When treating a large amount of flue gas, there is an uneven distribution of gas volume, and the thickness of the emulsion layer formed is different, resulting in a large difference in the desulfurization efficiency of each unit, which reduces the purification efficiency of the entire tower and makes the purification effect of the desulfurization tower unstable. In addition, when the actual working condition flue gas is very different from the designed flue gas volume of the desulfurization tower (more than 30%), the flue gas volume is too low, resulting in insufficient support for the flue gas to rise, and the emulsified suspension layer cannot be formed, which seriously affects the desulfurization and dust removal efficiency of the desulfurization tower.

[0003] Therefore, we proposed a pneumatic emulsification desulfurization device that can adapt to large fluctuations in gas volume in order to solve the above-mentioned problems.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field. Summary of the invention

[0005] The object of the present invention is to provide a pneumatic emulsification desulfurization device that can adapt to large fluctuations in gas volume, so as to solve the problems raised by the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a pneumatic emulsification desulfurization device capable of adapting to large fluctuations in gas volume, comprising:

[0007] An air equalizing chamber, wherein an air inlet is provided on the air equalizing chamber, and a flow guide is installed in the air equalizing chamber;

[0008] Multiple pneumatic units, multiple pneumatic units are installed on the top of the air equalization chamber, each pneumatic unit is installed with a cyclone, each pneumatic unit processes the same amount of flue gas, and some pneumatic units are installed with a gas volume regulating device on the top;

[0009] A spray chamber is installed on the top of the pneumatic unit.

[0010] Preferably, the deflector is composed of 3-5 concentric cones of different sizes, the angle between the cones and the horizontal plane is 30-70 degrees, and the height of the deflector is 600mm-1000mm.

[0011] Preferably, the level of the deflector is higher than the air inlet.

[0012] Preferably, the gas volume regulating device is composed of a cylinder, a rotating shaft, a cover plate and a base, and the base is connected to the upper plate of the pneumatic unit.

[0013] Preferably, the cylinder is controlled by a solenoid valve.

[0014] Preferably, a spray pipe and a demister are installed in the atomization chamber.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) When the device is in use, after the flue gas enters the air equalization chamber, the flue gas can fill the entire upper part of the air equalization chamber under the action of the guide, so that the flue gas in the air equalization chamber can evenly enter each pneumatic unit to prevent uneven distribution of the flue gas, thereby achieving equal gas volume in each filter unit and achieving the purpose of stable desulfurization efficiency.

[0017] (2) When the actual operating flue gas parameters differ greatly from the designed flue gas parameters (more than 30%), the flue gas treatment volume of the desulfurization device is kept matched with the actual flue gas volume by opening or closing the gas volume regulating device, thereby achieving the purpose of ensuring that the purification efficiency of the desulfurization device is not affected by changes in the actual flue gas volume.

[0018] The above summary is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present invention will be readily apparent by reference to the accompanying drawings and the following detailed description.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1

[0025] See also Figure 1-Figure 3 , a pneumatic emulsification desulfurization device capable of adapting to large fluctuations in gas volume, comprising:

[0026] The air equalizing chamber 2 is provided with an air inlet 1, and a deflector 5 is installed in the air equalizing chamber 2; the deflector 5 is composed of 3-5 concentric cones of different sizes, the angle between the cone and the horizontal plane is 30-70 degrees, and the height of the deflector 5 is 600mm-1000mm. The horizontal height of the deflector 5 is higher than the air inlet 1.

[0027] Multiple pneumatic units 3 are installed on the top of the air equalization chamber 2. A cyclone 6 is installed in each pneumatic unit 3. The flue gas volume processed by each pneumatic unit 3 is the same. A gas volume regulating device 7 is installed on the top of some pneumatic units 3. The gas volume regulating device 7 is composed of a cylinder 7-1, a rotating shaft 7-2, a cover plate 7-3 and a base 7-4. The base 7-4 is connected to the upper plate of the pneumatic unit 3. The cylinder 7-1 is controlled by a solenoid valve.

[0028] Atomizing chamber 4 is installed on the top of pneumatic unit 3. A spray pipe 8 and a demister 9 are installed in the atomizing chamber 4.

[0029] After the flue gas enters the equalizing chamber 2 through the air inlet 1, the gas is unevenly distributed. After passing through the deflector 5 in the equalizing chamber 2, the flue gas is dispersed by the deflector 5. The dispersed flue gas fills the upper layer of the equalizing chamber 2, so that the flue gas entering the pneumatic unit 6 can be fully distributed in each pneumatic unit 6, so that the thickness of the emulsion layer formed in each pneumatic unit 6 is similar, thereby ensuring that the desulfurization efficiency of each pneumatic unit 6 is the same.

[0030] When the gas volume regulating device 7 needs to be adjusted, the opening and closing of the cylinder 7-1 can be controlled by the solenoid valve to realize the opening and closing of the gas volume regulating device 7. When the actual flue gas volume is greater than the processing volume of the desulfurization device, the gas volume regulating device 7 can be opened to increase the processing gas volume of the desulfurization device to the actual working condition gas volume; when the actual flue gas volume is less than the processing volume of the desulfurization device, the processing volume of the desulfurization device can be reduced by closing the gas volume regulating device 7. By closing (opening) the gas volume regulating device 7, the pneumatic unit 6 in the closed (opened) state of the flue gas is prevented (promoted) from passing through, thereby ensuring that the flue gas volume passing through other pneumatic units 6 meets the design requirements, so that the processing gas volume of the entire desulfurization tower remains consistent with the actual changing working condition gas volume, thereby maintaining the formation effect of the suspension and ensuring the desulfurization and dust removal efficiency.
