Description

Technical Field

[0001] The utility model relates to the field of flue gas purification equipment, in particular to a flue gas purification device used for garbage incineration. Background Art

[0002] Waste incineration is a process of reducing the volume of waste through oxidation at high temperatures through appropriate thermal decomposition and combustion. A large amount of flue gas will be produced after waste incineration. The flue gas contains a large amount of harmful substances such as heavy metals and acidic gases, which will cause great harm to the earth's environment and human body. Therefore, the flue gas needs to be treated to prevent pollutants from being discharged into the air.

[0003] The purpose of flue gas desulfurization is to reduce the sulfur content in the emissions, reduce air pollution and the formation of acid rain. Wet flue gas desulfurization is to spray a certain concentration of limestone emulsion or alkaline solution into the flue gas, so that the SO2 in it reacts with the hydroxide in the solution to form sulfate, thereby achieving the purpose of removing sulfur.

[0004] In the process of desulfurization, the contact area between flue gas and limestone emulsion affects the efficiency of neutralization reaction. Existing purification devices are all through the contact between flue gas and sprayed limestone emulsion, and the means of increasing the contact area are limited. Therefore, those skilled in the art provide a flue gas purification device for waste incineration treatment to solve the problems raised in the above background technology. Utility Model Content

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0022] It should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "sleeved / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two components.

[0023] See also Figures 1 to 4 In this embodiment, a flue gas purification device for garbage incineration treatment is provided, including a box body 1, a slurry barrel 4 is connected to the bottom of the box body 1, a partition 8 is provided between the slurry barrel 4 and the box body 1, and a plurality of through holes are provided on the partition 8. A disturbance mechanism 7 is installed above the partition 8, and the disturbance mechanism 7 includes a fixed barrel 71, and a rotating seat 73 is rotatably connected to the upper end of the fixed barrel 71. A plurality of blades for dispersing smoke are connected to the outer side of the rotating seat 73. A hollow is provided inside the fixed barrel 71 and is connected to the slurry barrel 4 below. The fixed barrel 71 has the function of conveying lime slurry.

[0024] When in use, the rotating seat 73 can be rotated, and the rotation of the rotating seat 73 drives the outer blades to rotate together, so that the blades disturb the flue gas entering the inside of the box 1 to disperse it, and the flue gas can fully contact with the falling lime water during the rising process. At the same time, the lime water in the slurry tube 4 can be extracted through the fixed cylinder 71, and the lime water slides from the upper end of the rotating seat 73 and scatters on the outer surface of the rotating seat 73, thereby forming a layer of flowing lime water film. The flue gas contacts the lime water film, thereby increasing the means of neutralizing the flue gas reaction and improving the efficiency of flue gas purification. At the same time, a through hole is provided on the partition 8, so that the lime water can be used in repeated circulation, thereby making full use of the lime water and avoiding the replacement of the lime water when it is not saturated, thereby causing waste.

[0025] In further embodiments, see Figure 4The lower end of the fixed cylinder 71 is located inside the slurry cylinder 4, and a rotating rod 72 is inserted into the fixed cylinder 71. The upper end of the rotating rod 72 passes through the fixed cylinder 71 and is fixedly connected to the rotating seat 73. The lower end of the rotating rod 72 passes through the lower end of the slurry cylinder 4. A liquid inlet 74 is provided on one side of the lower end of the fixed cylinder 71, and a conveying auger is provided between the outer side of the rotating rod 72 and the fixed cylinder 71. The rotating rod 72 rotates to drive the rotating seat 73 to rotate, so that it disturbs and disperses the flue gas. At the same time, the rotating rod 72 drives the conveying auger to rotate, so that the lime slurry entering the fixed cylinder 71 through the liquid inlet 74 is transported to the top of the rotating seat 73 as the conveying auger rotates, and the lime slurry is dispersed along the outer surface of the rotating seat 73, thereby increasing the contact area between the lime slurry and the flue gas and improving the flue gas purification efficiency.

[0026] In further embodiments, see Figure 4 The outer side of the rotating rod 72 is fixedly connected to a connecting seat 75 located below the fixed cylinder 71, and a plurality of stirring rods 76 are fixedly connected to the outer side of the connecting seat 75. The rotating rod 72 also drives the connecting seat 75 to rotate during the rotation process, and the connecting seat 75 rotates through the stirring rods 76 to stir the lime slurry inside the slurry cylinder 4 to maintain the uniformity of the lime slurry.

[0027] In further embodiments, see Figure 2 A driving mechanism is installed below the slurry barrel 4, and the driving mechanism is connected to the rotating rod 72. The driving mechanism can be a motor, which is started to drive the rotating rod 72 to rotate, and the rotating rod 72 rotates to drive the rotating seat 73 to rotate and transport the lime slurry in the slurry barrel 4 to the top of the rotating seat 73.

[0028] In further embodiments, see Figures 1-2 A spray pipe 6 is installed on the upper part of the box body 1, and a delivery pump 5 is installed on one side of the box body 1. The delivery pump 5 is connected with the spray pipe 6 and the slurry barrel 4. The lime slurry in the slurry barrel 4 is delivered to the spray pipe 6 by the delivery pump 5, and the lime slurry is sprayed from the spray pipe 6, thereby increasing the contact area between the lime slurry and the flue gas inside the box body 1.

[0029] In a further embodiment, a discharge port is provided at the lower side of the slurry barrel 4, and a valve is installed on the discharge port. Thus, the saturated lime slurry is discharged and replaced with new lime slurry. A liquid level gauge can be provided on the slurry barrel 4, so as to facilitate observation of the amount of lime slurry inside, and facilitate discharge or addition of lime slurry.

[0030] In further embodiments, see Figure 1A smoke inlet 2 is fixedly connected to one side of the box 1, and the smoke inlet 2 faces the rotating seat 73. A smoke outlet 3 is connected to the top of the box 1. Smoke is input through the smoke inlet 2, and directly contacts the rotating seat 73 after entering the box 1. The purified smoke is discharged through the smoke outlet 3 and then other subsequent purification procedures are performed.
