Description

Technical Field

[0001] This utility model patent relates to the technical field of sodium bicarbonate desulfurization, mainly to a sodium bicarbonate processing desulfurization equipment. Background Art

[0002] Sodium bicarbonate dry desulfurization uses sodium bicarbonate as a desulfurizer to remove acidic gases such as SO2 from flue gas, and can achieve a desulfurization efficiency of 90%-95%. It is a flue gas treatment technology with a simple system, small footprint and low operating cost. Although the dry desulfurization process is simple, there is no sewage, and it is conducive to flue gas discharge, dry desulfurization is a gas and solid reaction with a slow reaction rate, resulting in a low utilization rate of sodium bicarbonate, and may cause undesulfurized flue gas to be discharged to the outside, causing air pollution. In this regard, we propose a sodium bicarbonate processing desulfurization equipment. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0019] For example, please refer to Figure 1-3A sodium bicarbonate processing desulfurization device comprises a reaction barrel 10, one side of the reaction barrel 10 is connected to an observation box 20, the reaction barrel 10 is provided with a plurality of cavities 11, the top of the reaction barrel 10 is connected to a driving mechanism 30, the driving mechanism 30 comprises a rotating motor 31 connected to the top of the reaction barrel 10, a first gear 32 connected to the driving end of the rotating motor 31, a second gear 33 meshingly connected to one side of the first gear 32 and a delivery pipe 34 connected to the bottom of the second gear 33, the delivery pipe 34 is provided with a plurality of vents 36, the outer wall of the delivery pipe 34 is provided with a plurality of stirring blades 35, the bottom of the delivery pipe 34 is connected to a rotary joint 40, and the bottom of the rotary joint 40 is connected to an air inlet pipe 50.

[0020] It should be noted that, in the embodiment, the rotating motor 31 drives the first gear 32 to rotate, thereby driving the second gear 33 to rotate, and then driving the delivery pipe 34 and the stirring blade 35 to rotate, so that the sodium bicarbonate in the cavity 11 floats up, and after the smoke enters the delivery pipe 34, it enters the cavity 11 through the vent 36, and the sodium bicarbonate and the smoke can fully react.

[0021] For example, please refer to Figure 2 A plurality of communication holes 17 are provided at the bottom of the two cavities 11 at the top, and a first dustproof net 12 is covered on the top of the communication holes 17 .

[0022] It should be noted that, in the embodiment, the connecting hole 17 facilitates the smoke at the bottom to enter the upper cavity 11, and the first dust-proof net 12 prevents sodium bicarbonate from entering other cavities 11. The smoke first enters the cavity 11 at the bottom, and the humid smoke obtained after the reaction enters the upper cavity 11, which can accelerate the reaction in the upper cavity 11.

[0023] For example, please refer to Figure 2 A plurality of discharge ports 13 are provided on one side of the reaction barrel 10 , and a sealing cover 14 is connected to one side of the discharge ports 13 , and the discharge ports 13 correspond to the cavities 11 one by one.

[0024] It should be noted that, in the embodiment, the discharge port 13 is convenient for replacing sodium bicarbonate.

[0025] For example, please refer to Figure 2 A gas outlet is provided on one side of the top of the reaction barrel 10, a second dustproof net 61 is fixed on one side of the gas outlet, one side of the gas outlet is connected to a connecting pipe 60, one side of the connecting pipe 60 is connected to an observation box 20, and an exhaust hole 21 is provided on one side of the bottom of the observation box 20.

[0026] It should be noted that, in the embodiment, the second dustproof net 61 prevents sodium bicarbonate from entering the connecting pipe 60, and the exhaust hole 21 is used to discharge the desulfurized gas.

[0027] For example, please refer to Figure 2 A reflux hole 15 is provided on one side of the top of the reaction barrel 10 , one side of the reflux hole 15 is connected to the observation box 20 through a pipeline, and a switch valve 70 is installed on one side of the pipeline.

[0028] It should be noted that, in the embodiment, the reflux hole 15 facilitates the undesulfurized flue gas in the observation box 20 to return to the reaction barrel 10 , and the switch valve 70 controls whether the reflux hole 15 is connected to the observation box 20 .

[0029] For example, please refer to Figure 3 An observation window 22 is installed on one side of the observation box 20.

[0030] It should be noted that, in the embodiment, the observation window 22 is convenient for observing whether the flue gas in the observation box 20 is black. If it is black, it means that desulfurization is not complete, and it is necessary to open the switch valve 70 to allow the flue gas to return to the reaction barrel 10 for desulfurization, or replace the sodium bicarbonate in the cavity 11.

[0031] For example, please refer to Figure 3 A plurality of anti-slip feet 16 are fixed to the outer wall of the reaction barrel 10 .

[0032] It should be noted that, in the embodiment, the anti-slip feet 16 are used to stabilize the reaction barrel 10 .

[0033] The specific operation mode of the utility model is as follows:

[0034] The sodium bicarbonate processing desulfurization equipment first drives the first gear 32 to rotate by rotating the motor 31, thereby driving the second gear 33 to rotate, and then driving the conveying pipe 34 and the stirring blade 35 to rotate, so that the sodium bicarbonate in the cavity 11 floats, and then the flue gas enters the conveying pipe 34 and enters the cavity 11 through the vent 36, so that the sodium bicarbonate and the flue gas can fully react;

[0035] Since the flue gas first enters the bottom cavity 11, the moist flue gas obtained after the reaction enters the upper cavity 11 through the connecting hole 17, making the upper flue gas moist, which can accelerate the reaction in the upper cavity 11. The desulfurized flue gas enters the observation box 20 for observation, avoiding the discharge of undesulfurized flue gas;

[0036] If black smoke appears in the observation box 20, close the exhaust hole 21 and open the switch valve 70 to allow the smoke to return to the reaction barrel 10 for desulfurization. If the smoke is still black, the sodium bicarbonate in the cavity 11 needs to be replaced.

[0037] The above-described embodiments only express the implementation methods of the present application, but for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
