Description

A gas purification apparatus that improves the mixing and dissolving function of chemicals and reduces waste {A Gas Purification Apparatus with Improved Mixture of Chemicals and Reduced Waste of Chemicals}

The present invention relates to a gas purification device, and more specifically, to a gas purification device that improves the mixing and dissolving functions of chemicals and reduces waste through improved gas-liquid contact.

As industrialization progresses, efforts are being made to strengthen environmental regulations and reduce air pollutants around the world due to air pollution and environmental destruction. A wet gas purification device used for the purpose of reducing air pollution is a device that purifies contaminated gas by bringing it into contact with a cleaning liquid, and removes particulates, water-soluble substances, and substances that can be neutralized or oxidized in the contaminated gas.

In this way, in a gas purification device where gas and liquid come into contact, fillers with a large specific surface area are filled to form a filler layer, and a cleaning solution is sprayed on the filler layer to form a thin water film layer on the surfaces of the fillers. The polluted gas to be purified is blown to the filler layer by a blower, and when the water film formed by spraying the cleaning liquid on the surface of the filler and the polluted gas come into contact with each other, material transfer and reaction occur through gas-liquid contact, and in this process, purification of pollutants occurs. It will come true.

Among pollutants, particulate matter such as dust is collected in the water film, acid gas is mainly neutralized by a cleaning solution containing dissolved caustic soda (NaOH), and mercaptan, which is a odor-causing substance, is oxidized and decomposed by oxidizing agents such as sodium hypochlorite. do. In this way, since purification occurs through gas-liquid contact in the water film on the surface of the filler, it is desirable to increase the contact speed and frequency by increasing the surface area of the filler as much as possible to increase the contact area and form turbulence.

By continuously spraying the cleaning solution onto the filler layer using a spray means such as a nozzle, the water film on the surface of the filler is continuously replaced and regenerated by the newly sprayed cleaning solution, thereby maintaining purification performance. In this way, not only must the cleaning liquid be replaced and regenerated at the gas-liquid contact surface where the water film on the surface of the filler and the contaminated gas come into contact with each other, but the purification of the contaminated gas continues by exhausting the gas purified through gas-liquid contact and contacting the newly incoming contaminated gas. It must be done as much as possible. Therefore, it is desirable for the gas flow to be fast and strongly turbulent so that the contact interface can be continuously regenerated. In this way, in the purification process through gas-liquid contact, the supply of cleaning liquid and the regeneration of the interface through the formation of gas turbulence are very important.

In addition, in the purification of contaminated gas, not only the contact between the cleaning fluid water film formed on the surface of the filler and the contaminated gas, but also the gas-liquid contact in which the cleaning fluid droplets, which are mainly sprayed downward, and the contaminated gas, which is mainly blown upward, directly collide with each other play an important role. Since the collision speed and collision frequency are important in the purification action by direct collision between the cleaning liquid and polluted gas, it is desirable to spray the cleaning liquid as finely as possible to increase the total surface area of the droplets, and the flow of the polluted gas should be as even and strong as possible. However, conventional fillers are so focused on reducing blowing resistance that they focus on the size of the pores and porosity and do not sufficiently consider the specific surface area. While the turbulent flow that increases gas-liquid contact is important, the filler itself is used. Therefore, the formation of turbulence is not properly considered, so improvement is required.

In addition, in order to increase cleaning performance through gas-liquid contact, the collision speed and collision frequency at which contaminants in the gas and the cleaning liquid collide with each other must be increased as described above. Therefore, not only must the spraying speed of the cleaning liquid be increased, but it is also desirable that the contaminated gas has a strong turbulent flow. Among the components of the gas purification device, the places where turbulence is most strongly formed are the inside of the blower casing, where the rotor rotates at high speed, and the space around the rotor and the rotor. However, in the conventional gas purification device, elements such as the internal space of the blower casing and the rotary wheel are not properly used for gas-liquid contact, and the blower is used only to generate flow energy for transport of gas, so improvement is required.

In addition, in order to increase gas purification performance, it is important to increase the above-mentioned gas-liquid contact area as well as increase the contact time and contact frequency to secure sufficient collection time and sufficient reaction time for neutralization and oxidation. In order to achieve this goal, conventional technology mainly focuses on greatly expanding the cleaning room or increasing the amount of filler, making it uneconomical in terms of site requirements and facility costs. However, ducts that provide a flow path for transporting polluted gases are not utilized for purification of polluted gases, despite securing a significant residence time while the gases are being transported, so improvements are required.

In addition, chemicals are often injected in conventional scrubbing gas purification devices, but they are inefficient because they are mainly put into a cleaning fluid storage tank and dissolved without a separate line mixer. It is difficult to install a mechanical line mixer in the cleaning liquid storage tank located at the bottom of the cleaning tower. A device that mixes and dissolves the cleaning liquid being transferred and the chemical solution by installing a line mixer in the cleaning liquid transfer line extending from the discharge port of the cleaning liquid transfer pump to the spray means may be considered. However, in the conventional line mixer, a plurality of irregularly bent metal pieces are arranged in a row and installed inside the pipe, so it does not form an even and fine turbulent flow. Instead, a turbulent flow is formed that is irregular and has a large flow radius, resulting in large head loss and power consumption. There are too many problems and improvements are needed.

Gas purification performance can be improved by increasing gas-liquid contact with the contaminated gas blown by the blower 320 inside the room 310 and increasing mass transfer and solids collection.

Hereinafter, in the following description of FIGS. 2 and 3, the structure and operation of the first to second embodiments of the filler provided in the gas purification device of the first embodiment according to the present invention will be described in detail.

Figure 2 is a perspective view showing the concept of the first embodiment of the filler provided in the gas purification device according to the present invention.

Figure 3 is a plan view showing the concept of the first embodiment of the filler provided in the gas purification device according to the present invention.

The filler 100 according to the first embodiment of the present invention shown in FIGS. 2 and 3 is mainly molded from a hard synthetic resin material, is open on both sides to form openings that penetrate each other, and has a length relatively compared to the diameter. It is a configuration in which a blade 225 that generates a rotational flow is installed on the inside of a tubular single pipe member 221 that is short and has a mainly circular opening cross-section.

The blades 225 that generate rotational flow are provided to protrude from the inner surface of the short pipe member 221 toward the center, and are composed of a plurality of blades disposed inclined at a predetermined angle with the longitudinal direction of the short pipe member 221.

The plurality of blades 225 according to the present invention are combined to form one propeller, that is, an impeller that induces an axial fluid flow, and converts the flow energy of the fluid into rotational power or the rotational power into flow energy. Its purpose and configuration are different from the rotating pump of the converting pump. The blades 225 in the present invention are used to induce a change in the flow form by converting the straight flow of fluid into a rotating flow, so they do not require a rotating shaft. Therefore, to minimize flow path reduction and fluid resistance, the central axis and hub are omitted and the ends of the blades 225 are concentrated. In a typical fluid machine, the central part where the rotation axis is installed is empty and the blades 225 are not connected to each other. Each is composed of separate, independent members.

The fluid flowing toward the opening of the short pipe member 221 comprised in the filler 100 of the present invention is converted into a rotational flow by the blade 225 disposed inclined at a predetermined angle while passing through the short pipe member 221. do.

The cleaning liquid is sprayed with a pump to form a water film on the surface of the filler 100, and the contaminated gas is blown away with a blower. When air is supplied, the contaminated gas flow flowing through the single pipe opening of the single pipe member 221 is converted into a rotating flow by the blades 225, so turbulence can increase and gas-liquid contact can increase.

In this way, the filler 100 according to the present invention converts the straight gas flow into a rotational flow and creates a turbulent flow, so gas-liquid contact can be improved.

In addition, by further including a cut portion 106 in the short pipe member 221, which is formed in the short pipe member 221 and cut in the longitudinal direction so that the lateral directions communicate with each other, and increasing the specific surface area, a water film of the cleaning liquid can be formed. The surface area of the filler 100 can be increased and more turbulence can be formed, thereby further improving gas-liquid contact.

In addition, if the blade 225 is provided with a plurality of through holes 105 that penetrate the front and back sides, the specific surface area of the blade 225 is further increased and fluid flows through the through holes 105. While additional fine turbulence is generated by the through holes 105, fluid resistance can be reduced.

Therefore, in the gas purification device filled with the filler 100 according to the present invention, the dissolution rate at which gaseous, liquid, and solid dissolved substances, etc. are dissolved in the cleaning liquid is increased, so that cleaning performance can be improved and solid substances such as dust, etc. It can also be well captured by the cleaning solution.

In addition, the filler 100, which has a large porosity and specific surface area, is made of a non-toxic material that is not biotoxic, and is filled in a cleaning chamber to attach and proliferate a biofilm on the surface in a wet state. When it comes into contact with a contaminated gas, the biodegradation contained in the gas is carried out. Sexual pollutants are biologically decomposed, making it possible to purify the gas and remove bad odors.

In addition, the filler 100 according to the first embodiment of the present invention having the above-mentioned structure has a large specific surface area and porosity and improved gas-liquid contact performance, so it can be applied to a physicochemical washing tower where chemicals are introduced, etc. to increase purification performance. .

The filler 100 according to the present invention of this configuration has a relatively large porosity and specific surface area compared to the volume, and generates rotational flow and turbulence, so it can be installed in reactors, washing towers, etc. to increase the contact area and contact frequency between gas and liquid. there is. Therefore, in the gas purification device filled with the filler 100 according to the present invention, the dissolution rate of dissolved substances in the gas phase, liquid phase, and solid phase is increased, so the cleaning performance can be improved, and solid substances such as dust are also easily removed by the cleaning liquid. can be captured.

Figure 4 is a perspective view showing the concept of a second embodiment of the filler provided in the gas purification device according to the present invention.

As shown in Figure 4, the filler 100 according to the second embodiment of the present invention, in addition to the filler of the first embodiment, further includes a member whose length is longer than the width and whose cross-section is in an inverted streamline shape. The reverse streamlined member 107 may be provided on the outer surface along the circumference of the short pipe member 221 provided in the filler of the first embodiment. In addition, the reverse streamlined member 107 provided in the second embodiment may be configured in a circular shape by extending a plurality from the inlet side outer edge of the single pipe member 221, as shown in FIG. 4, or may be configured in a hemispherical shape. there is.

As shown in the enlarged cross-sectional view shown on one side of FIG. 4, the fluid flowing through the tip of the inverted streamlined member 107 flows to the rear portion of the inverted streamlined member 107, where both sides are angled at an acute angle and the rear portion is flat. This can convert to turbulent flow and increase gas-liquid contact. While a general streamlined structure minimizes the occurrence of turbulence and reduces fluid resistance, the filler according to the second embodiment of the present invention described above increases turbulent flow and further improves gas-liquid contact by adding an inverted streamline member 107. It was done.

The pipe 340 can be communicated to inject a chemical solution. If an oxidizing agent, etc. is added to the cleaning liquid storage tank 360 and dissolved, the oxidizing agent may be consumed and wasted by reducing substances in the storage tank while it stays in the storage tank. Therefore, in the gas purification device of the second embodiment, the oxidizing agent is directly transferred to the spray means 350 to be used for the purification reaction of the gas, thereby preventing waste of the oxidizing agent due to reducing substances in the storage tank. As such, in this embodiment, chemicals such as oxidizers are directly added to the cleaning fluid transfer pipe 340, and the line mixer 200 is used to stir and dissolve the cleaning fluid while it is being transported, and then use it immediately for gas purification, thereby reducing unnecessary waste of chemicals.
