Description

HIGH SPEED CENTRIFUGAL ATOMIZATION MIXING NET FOR EXHAUST OUTLET PIPE}

The present invention relates to an exhaust gas purification treatment equipment. Specifically, the high-speed centrifugal spray agitation net acting on the exhaust gas exhaust pipe sufficiently mixes the exhaust gas and water mist, and also rapidly removes toxic substances and dust in the exhaust gas. It can be incorporated into the fog and at the same time reduce the heat of the exhaust gases.

With the development of the industry, the exhaust gas emission is gradually increased and seriously affects the normal life of mankind, and the exhaust gas treatment equipment is attracting attention day by day. Current exhaust gas treatment equipment mainly sprays water on the exhaust gas to mix toxic substances and dust in the exhaust gas with water droplets to separate the air from the air. The problem with such equipment is how to improve the spraying effect, increasing the contact area of exhaust gas and water to the maximum, so that toxic substances and dust can be sufficiently mixed with water. Applicant filed on December 11, 2009, "High Speed Centrifugal Spray Blade", filed with Chinese application number "ZL200920202313.X", includes an axial sleeve connected to an inlet pipe and several sloping blades installed in the axial sleeve. do. The inclined centrifugal discharge groove provided on the shaft sleeve sidewall is between two adjacent blades. Many centrifugal drainage holes are distributed in the annular stop plate fitted to the front end of the shaft sleeve. The net cover installed in front of the shaft sleeve is fixed to the blade, and there are several layers of net sheet inside the net cover. The disadvantage of this original structure is that most of the waste gas is attached to the inner wall of the pipe and discharged directly without passing through the spray net filter. This results in the exhaust gas not coming into sufficient contact with the water mist, thus affecting the filtering.

China application number: ZL200920202313.X (2009.12.11)

It is an object of the present invention to provide a high speed centrifugal spray stirring net which overcomes the shortcomings and shortcomings of the current technology described above and prevents exhaust gases from being directly discharged without passing through the spray net and at the same time makes the exhaust gas and water mist sufficiently contacted. ,

In order to realize the above object, the present invention takes the following technical solutions. The high speed centrifugal atomizing agitator net used in the exhaust gas exhaust pipe is a rotating spray pipe, a shaft sleeve fixed to the spray pipe, and an air guide blade and spray net installed in front of and behind the shaft sleeve, and a shaft sleeve on the side wall of the spray pipe. And spray holes installed opposite to each other, and several sloped spray grooves mounted on the sidewalls of the shaft sleeves. The end of the air induction blade is bent, the bent direction is the same as the inclined direction of the air induction blade. The air guide blade ends and the edge of the spray net were connected to each other to form a stop plate.

The inner wall of the shaft sleeve is provided with a recessed spray cavity, which is opposed to the spray hole of the spray pipe.

A plurality of air circulation blades are installed on the side wall of the spray net, and the inclination directions of the air circulation blades and the air induction blades are opposite to each other.

The spray net may be a steel net of several layers of discs.

The present invention is mainly installed in the exhaust gas discharge pipe. The water sprayed out of the hole in the spray pipe is sprayed out of the cavity first, then through several sloped spray holes. The sprayed water mist runs out of the outer wall of the shaft sleeve under high velocity air induction. At this time, the water mist is scattered into small grains due to the spray net rotating at high speed to form a mist wall in the cross section of the pipe. Toxic substances and dusts in the exhaust gas are rapidly incorporated into the water mist to lower the heat of the exhaust gas. In addition, the equipment can suppress airflow from the pipe walls. The air circulation blades on the sidewalls of the spray nets reverse the flow of air on the inner wall of the pipes, allowing the exhaust gases to pass through the central spray nets and to filter them. This solved the difficulty of passing the exhaust gas directly to the inner wall of the pipe without passing through the spray net, and exhibited an ideal purification effect by sufficiently contacting the exhaust gas with water mist.

FIG. 2 is a perspective view of direction A of FIG. 1.

As shown in Figs. 1 and 2, the present invention relates to a high speed centrifugal spray agitation net acting on the exhaust gas exhaust pipe, which is fixed to the rotatable spray pipe (7) and the spray pipe (7). It includes an air induction blade 4 and a spray net 3 installed in front of and behind the eve 6 and the shaft sleeve 6. The spray pipe 7 is driven by a motor to rotate at high speed. The shaft sleeve 6 is connected with the spray pipe 7 with a screw 9. Therefore, the shaft sleeve 6, the air induction blade 4, the spray net 3 rotates with the spray pipe 7 at high speed. The spray hole 10 is provided in the side wall of the spray pipe 7. A hollow spray cavity 8 is provided on the inner wall of the shaft sleeve 6, and the spray cavity 8 is opposed to the spray hole 10 of the spray pipe 7. Several inclined spray grooves 5 are provided on the side wall of the shaft sleeve 6. The water droplets sprayed from the spray hole 10 of the spray pipe 7 repeatedly collide with each other in the spray cavity 8, and then are sprayed into a plurality of inclined spray grooves 5, under the action of high speed air induction. A high speed centrifugal water mist wall is formed by coming out of the outer wall of the shaft sleeve 6 and contacting the spray net 3 rotating at a high speed. Since the air induction blade 4 is installed at the front end of the shaft sleeve, the rotation of the air induction blade 4 will accelerate the flow of the first atomized mist sprayed from the exhaust gas and the spray groove 5. Can be. The spray net 3 is formed of several layers of disc-shaped steel nets and is installed on the rear side of the air induction blade 4. The high speed rotating spray net 3 disperses the water mist into small grains, forming a mist wall in the cross section of the pipe. When the exhaust gas passes through the high-speed rotating fog wall, the toxic substances and dust in the exhaust gas rapidly mix with the mist and lower the heat quantity of the exhaust gas. The end of the air induction blade 4 is bent, and the bent direction is the same as the inclination direction of the air induction blade 4. The stop plate 1 was formed by connecting the end of the air induction blade 4 and the edge of the spray net 3 with each other. The stop plate 1 suppresses most of the air flow to the pipe wall, allowing the exhaust gas to pass through the central spray net and filtering it, thereby preventing direct air flow. Several air circulation blades 2 are installed on the side wall of the spray net 3, and the inclination directions of the air circulation blades 2 and the air guide blades 4 are opposite to each other. The air circulation blade (2) reverses the air flow adhering to the inner wall of the pipe, and filters the exhaust gas into sufficient contact with the mist wall formed in the spray net, thereby exhibiting an ideal purifying effect.
