Detailed Description
The present application is described in further detail below with reference to figures 1-6.
The embodiment of the application discloses whirlwind collision dust removal preprocessing device. Referring to fig. 1 and 2, the cyclone collision dust removal pretreatment device comprises a frame 1, a dust gas pretreatment mechanism 2 and a dust collection mechanism 3; dust gas pretreatment mechanism 2 installs in frame 1, and before handling shouting dirt gas through the main part dust remover, let in dirt gas pretreatment mechanism 2 with dirty gas earlier, filter the separation through most granule dust of dirt gas pretreatment mechanism 2 in to dirt gas, let dirt gas just carry out dust filtration once before not getting into the main part dust remover. And collection dirt mechanism 3 is then installed on dirt gas pretreatment mechanism 2, the dirty gas that contains the large granule dust realizes the initial gross separation in dirt gas pretreatment mechanism 2 and filters the back, most granule dust can enter into collection dirt mechanism 3 and store in for the dust content who stays in the dirty gas in dirt gas pretreatment mechanism 2 has become fewly, at this moment let in this part dirty gas carry out the secondary filter in letting in the main part dust remover again, the main part dust remover is difficult for producing the jam this moment.
As shown in fig. 1 and 2, the dust gas pretreatment mechanism 2 includes an air inlet 21, an air outlet 22, a cylindrical portion 23, and a tapered cylindrical portion 24; the cylindrical part 23 is bolted or welded to the frame 1, the cylindrical part 23 in this case being a cylinder in the shape of a cylinder, and the conical part 24 in this case being a cylinder in the shape of a truncated cone; the tapered cylinder part 24 is connected below the cylinder part 23, the tapered cylinder part 24 is communicated with the inside of the cylinder part 23, the opening end of the end with larger area of the tapered cylinder part 24 is close to the cylinder part 23, the cross-sectional area of the opening end with larger area of the tapered cylinder part 24 is the same as that of the cylinder part 23, the opening end of the end with smaller area of the tapered cylinder part 24 faces the ground surface, namely, the tapered cylinder part 24 gradually reduces from the cylinder diameter near the cylinder part 23 to the cylinder diameter near the dust collecting mechanism 3, and the dust collecting mechanism 3 is connected on the opening end of the tapered cylinder part 24 facing the ground surface.
As shown in fig. 1 and 2, the air inlet 21 is a cylindrical pipe made of iron or steel, and a non-stick material such as teflon is coated inside the pipe to prevent excessive accumulation of dust in the air inlet 21. One end of the air inlet 21 is communicated with the inside of the cylindrical part 23, and the length direction of the air inlet 21 is consistent with the tangential direction of the cross section of the cylindrical part 23, so that when the dust-containing gas is introduced into the cylindrical part 23 from the air inlet 21, the dust-containing gas also enters the inside of the cylindrical part 23 from the tangential direction of the cross section of the cylindrical part 23, the entering dust-containing gas is easy to form a bypass flow, and the dust-containing gas is attached to the inner wall of the cylindrical part 23 and flows in a rotating manner from top to bottom; and the position where the air inlet part 21 is communicated with the cylindrical part 23 is positioned on the cylindrical wall of the cylindrical part 23 close to the top, so that the dust-containing air stays in the cylindrical part 23 for a longer time when moving from top to bottom after entering the cylindrical part 23, and the filtering effect is better.
As shown in fig. 2 and 3, the air outlet 22 is a single pipe made of iron or steel, and a non-stick material such as teflon is also coated inside the air outlet 22, so that the possibility of dust accumulation on the inner surface of the air outlet 22 is reduced. The air outlet portion 22 is communicated with one end of the cylindrical portion 23 far away from the tapered cylindrical portion 24. The air inlet pipe of the external main body dust remover is communicated with the air outlet part 22, so that the communication relation between the external main body dust remover and the application is realized. The cylinder part 23 and the tapered cylinder part 24 are also formed with relative negative pressure by the high negative pressure inside the external main body dust collector.
When negative pressure is formed inside the cylindrical part 23 and the tapered cylindrical part 24, relative negative pressure is formed between the inside of the cylindrical part 23 and the outside, and dust-containing gas entering through the air inlet part 21 can be rapidly sucked into the cylindrical part 23, and due to the difference of pressure, the dust-containing gas entering the cylindrical part 23 generates kinetic energy under the action of pressure difference and moves in the cylindrical part 23 at a certain speed; the dust-containing gas which is sucked at this time collides with the inner walls of the cylindrical part 23 and the tapered cylindrical part 24 and stalls, and dust in the dust-containing gas falls to the bottom of the tapered cylindrical part 24 under the action of the gravity of the dust-containing gas, especially dust with a large size, and the dust is more easily dropped out in the process of the dust-containing gas moving inside due to heavier weight, so that the dust is collected and filtered. Further, the flow direction of the dust-containing gas in the cylindrical portion 23 and the tapered cylinder portion 24 forms a vortex, and the residence time of the dust-containing gas in the cylindrical portion 23 and the tapered cylinder portion 24 can be extended. The longer the time, the better the filtering effect of the dust in the dust-containing gas.
As shown in fig. 4 and 5, a gas baffle plate 4 is mounted in the cylindrical portion 23 at a position close to the air intake portion 21, the gas baffle plate 4 is welded to the inner ceiling wall of the cylindrical portion 23, the gas baffle plate 4 is an arc-shaped plate, and the arc surface of the gas baffle plate 4 is matched with the arc surface of the cylindrical portion 23. A flow guide cavity 5 is reserved between the gas flow guide plate 4 and the inner wall of the cylindrical part 23, and dust-containing gas entering the cylindrical part 23 from the gas inlet part 21 firstly enters the flow guide cavity 5. Referring to fig. 6, the gas baffle plate 4 is provided with a plurality of buffer chambers 41 along the longitudinal direction of the gas baffle plate 4, and one side of each buffer chamber 41 opens into the buffer chamber 41, and the other side opens out of the buffer chamber 41 and is also located in the cylindrical portion 23. The inner wall of the buffer cavity 41 is provided with a plurality of buffer arc plates 42 along the length direction of the buffer cavity 41 in a hinged mode through a torsion spring 43, one end of the torsion spring 43 is connected with the inner wall of the buffer cavity 41, the other end of the torsion spring is connected with one side plate edge of each buffer arc plate 42, and the torsion spring 43 enables the buffer arc plates 42 to be always kept at the current position. One side of each buffer arc plate 42, which is far away from the torsion spring 43, extends towards the opening of one side of the buffer cavity 41, which is far away from the diversion cavity 5, and two adjacent buffer arc plates 42 are respectively hinged on two cavity walls of the buffer cavity 41.
When the dust-containing gas enters the cylinder part 23 from the air inlet part 21, a part of the dust-containing gas can stably rotate spirally along the inner wall of the cylinder part 23, and the other part of the dust-containing gas can be separated from the rotating track of the cylinder part 23 close to the inner wall when entering the cylinder part 23 from the air inlet part 21, directly enters the middle part of the cylinder part 23 and spreads in the middle part of the cylinder part 23, and the dust in the part of the dust-containing gas is not easy to be separated by centrifugal force, so that the filtering effect can be reduced; therefore, after the gas guide plate 4 is arranged, the dust-containing gas entering the cylindrical part 23 from the air inlet part 21 directly enters the guide cavity 5 and is not easy to disperse, so that the dust-containing gas which originally can be separated from the inner wall of the cylindrical part 23 can continuously move along the inner wall of the cylindrical part 23 after being shielded by the gas guide plate 4, and the problem that the dust-containing gas entering the cylindrical part 23 is dispersed to cause poor filtering effect is solved. However, after the gas enters the flow guide cavity 5, the gas guide plate 4 is easily broken by the dust-containing gas due to the huge impact force because the dust-containing gas has too high speed and large impact force caused by the difference of internal and external pressures and the space of the flow guide cavity 5 is narrow. Therefore, in order to avoid the above situation, the plurality of buffer chambers 41 on the gas baffle plate 4 can be used for a part of a small amount of dust-containing gas to enter, and the impact force of the dust-containing gas entering the baffle chamber 5 from the gas inlet part 21 is weakened. After the small amount of dust-containing gas enters the buffer chamber 41, the buffer arc plate 42 disposed in the buffer chamber 41 blocks the dust-containing gas, so as to weaken the impact force of the dust-containing gas entering the buffer chamber 41.
That is, after the dust-containing gas contacts the buffer arc plate 42, under the elastic force of the torsion spring 43, the buffer arc plate 42 will slightly shift after receiving the impact force, and convert the impact force of the dust-containing gas into the power of the buffer arc plate 42, and the multiple buffer arc plates 42 will sequentially weaken the impact force of the dust-containing gas, thereby reducing the impact force of the dust-containing gas in the whole diversion cavity 5. After setting up like this, only can prevent that dusty gas from taking place the problem of dispersion, can solve dusty gas's impact force again and too big cause the problem that gas guide plate 4 damaged, and then the filter effect of dusty gas has been promoted from the side.

As shown in fig. 2, the dust isolating mechanism 6 is mounted on the communicating pipe 321, the dust isolating mechanism 6 includes an upper valve 61 and a lower valve 62, the upper valve 61 and the lower valve 62 are both mounted on the communicating pipe 321, and an isolating space is formed between the upper valve 61 and the lower valve 62 on the communicating pipe 321. In this embodiment, butterfly valves are selected for the upper layer valve 61 and the lower layer valve 62. In other embodiments, a manual gate valve, a pneumatic ball valve, or a pneumatic stop valve may be selected.
When dust removal and filtration are performed in an industrial plant environment of laser welding or other welding, dust-containing gas with scattered sparks may be sucked into the cylindrical portion 23 from the plant environment, and when dust-containing gas with scattered sparks flows in the cylindrical portion 23, there is a high possibility that flames may occur due to collision between the scattered sparks. At this time, the upper valve 61 is opened and the lower valve 62 is closed to communicate the tapered tube part 24 with the communication pipe 321, so that the dust in the tapered tube part 24 can directly enter the communication pipe 321 without continuously moving into the dust collection tube 311, and then the upper valve 61 is closed to completely locate the dust in the isolation space between the upper valve 61 and the lower valve 62. If there is a flame in the dust, the dust will be in the isolation space of the communication pipe 321 and will not enter the cone part 24 and the dust collection barrel 311, so as to achieve the effect of sufficient isolation; after the flame is extinguished, the lower valve 62 is opened to introduce the dust into the dust collecting cylinder for storage.
As shown in fig. 1 and 2, in the present embodiment, the tapered cylinder portion 24 is provided with a fire extinguishing connection pipe 7 in communication, and the fire extinguishing connection pipe 7 is used for connecting with external fire extinguishing equipment. In other embodiments, the fire extinguishing nipple 7 can also be arranged in communication with the cylindrical portion 23. The fire extinguishing connecting pipe 7 is used for being connected with external fire extinguishing equipment, if dust-containing gas with sporadic sparks is sucked into the conical cylinder part 24 and then is subjected to afterburning, the external fire extinguishing equipment can be directly communicated with the interior of the conical cylinder part 24 through the fire extinguishing connecting pipe 7, and therefore the effect that fire extinguishing materials are sprayed into the conical cylinder part 24 in time to extinguish dust can be achieved. And, the sprayed fire extinguishing material includes, but is not limited to, fire retardant gas for fire extinguishing bottles, gas-liquid mixture, etc.
As shown in fig. 1, the temperature sensor 8 is further attached to the tapered tubular portion 24, and the temperature sensor 8 measures the temperature inside the tapered tubular portion 24. It is to be noted that, since dust with sparks falls into the tapered cylindrical portion 24 by its own weight after entering the cylindrical portion 23, if a re-ignition occurs, the re-ignition also occurs in the tapered cylindrical portion 24. Therefore, the temperature sensor 8 only needs to be attached to the tapered tube portion 24 to detect the temperature in the tapered tube portion 24 at any time, and the temperature sensor 8 does not need to be attached to the cylindrical portion 23.
Through setting up temperature sensor 8, under the condition that can not directly see the interior of tapered cylinder portion 24, can judge whether the inside after combustion takes place through the temperature information of temperature sensor 8 transmission to can make things convenient for the staff in time to discover the crisis condition.
As shown in fig. 1 and 2, an inert gas connecting pipe 9 is connected to the cylindrical portion 23, and the inert gas connecting pipe 9 is used for introducing an inert gas to the outside. When dust-containing gas with sparks enters the cylindrical part 23, the dust-containing gas with sparks is likely to explode in an internal pressure environment after being re-ignited, and inert gas can be introduced in time through the inert gas connecting pipe 9, so that the dust-containing gas in the cylindrical part 23 is not easy to explode when being re-ignited.
Specifically, a control box 91 is installed on the frame 1, the control box 91 is communicated with the inside of the cylindrical part 23 through an air pipe 92, an electromagnetic valve or an electric valve for controlling the opening and closing of the pipe is installed on the air pipe 92, and the control box 91 is connected with an external inert gas storage device through a pipe, that is, a part of inert gas is stored in the control box 91. When the control box 91 detects that the dust concentration in the cylindrical part 23 is too high, the control box 91 controls the electromagnetic valve or the electric valve to be opened, so that the external inert gas equipment can introduce inert gas into the control box 91 through the pipeline, and then the inert gas is introduced into the cylindrical part 23 from the control box 91 through the gas pipe 92, and the process is called as "inerting dust". Its aim at, when dust concentration is too high, very easily take place the spark and ignite again and then produce the explosion, and can in time let in the drum portion 23 with inert gas through above-mentioned structure for lose the explosiveness after dust and the inert gas mixture, thereby realize the blast proof effect in the drum portion 23.
The implementation principle of the cyclone collision dust removal pretreatment equipment in the embodiment of the application is as follows: the dust-containing gas in the working environment is introduced into the main body dust remover. The dust-containing gas is firstly introduced into the cylindrical part 23, under the action of the pressure difference between the cylindrical part 23 and the outside, the dust-containing gas can enter the cylindrical part 23 and collide with the inner wall of the cylindrical part 23 to stall, so that dust in the dust-containing gas falls to the bottom of the conical cylinder part 24 under the action of self gravity, the flow direction of the dust-containing gas in the cylindrical part 23 and the conical cylinder part 24 forms a vortex, the staying time of the dust-containing gas in the cylindrical part 23 and the conical cylinder part 24 is prolonged, and the filtering effect of the dust-containing gas is improved; if the dust-containing gas with the sporadic sparks is sucked, in order to prevent the sparks from reigniting in the cylindrical part 23 and the tapered cylinder part 24, the upper valve 61 is opened to close the lower valve 62, so that the dust with the sporadic sparks falls into the communicating pipe 321, and then the upper valve 61 is closed, so that the dust with the sporadic sparks is in the isolated space of the communicating pipe 321 until the sparks are extinguished. Then, the lower valve 62 is opened to introduce the dust into the dust collecting container 311 for storage.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
