Specifically, the highest position of the collection bucket 14 is the opening position of the collection bucket 14 in the housing 1. The highest position of the collection bucket 14 can be the same as the highest position of the liquid level of the gas water, or it can be slightly higher than the gas water level. The highest position of the liquid level of water, like this, when can avoid dust scraper 12 work on the water, a large amount of liquids on the liquid level directly flow out from collecting bucket 14.

FIG. 2 is a schematic structural view of the collecting bucket 14 in the primary tar separator shown in FIG. 1 . Each collecting bucket 14 includes a collecting groove 141 located in the housing 1 and a diversion bucket 142 located outside the housing 1 which communicate with each other; ; The diversion bucket 142 is used to clean up floating dust and impurities. Wherein the highest position of the collection tank 141 located inside the housing 1 is equal to or slightly higher than the highest position of the liquid level of the gas water, and the collection tank 141 extends from the bottom to the outside of the housing 1, collecting The part of the bucket 14 located outside the housing 1 can be referred to as a diversion bucket 142, and the diversion bucket 142 can flow out the floating dust and impurities collected by the collection tank 141 from the diversion bucket 142, that is to say, the diversion bucket 142 Outlet 143 needs to be set in the center, so as to facilitate the regular cleaning of the collected floating dust and impurities.

In practical applications, the water dust scraper 12 can also adopt other regular or irregular shapes, as long as it can scrape off floating dust and impurities. In the embodiment shown in FIG. 3 , two water dust scrapers 12 are arranged symmetrically as an example. In practical applications, there may be one water dust scraper 12 , or multiple water dust scrapers 12 may also be provided. Similarly, in the embodiment shown in FIG. 1 and FIG. 3 , two collecting buckets 14 are arranged symmetrically as an example. In practical applications, one or more collecting buckets can be installed.

It should also be noted that, in the embodiment of the present invention, the rotation direction of the water dust scraper 12 driven by the central shaft 8 is preferably clockwise. When changing the direction of rotation, for example, when rotating counterclockwise, it is necessary to adjust the water dust scraper 12 shown in Figure 3, so that the arc-shaped raised part of the water dust scraper 12 is towards the direction of rotation, which can facilitate scraping off the dust on the liquid surface. Floating dust and impurities.

In order to further facilitate the rotation of the water dust scraper 12, the end of the water dust scraper 12 can be made of soft material, so that the water dust scraper 12 will not be affected when passing through the collecting bucket 14. Optionally, as shown in Figure 3, the end of the water dust scraper 12 can be made slightly longer, so that when the water dust scraper 12 rotates around the central shaft 8, the end of the water dust scraper 12 is close to the housing 1, it is convenient to scrape off all the floating dust and impurities floating on the liquid surface.

Further, as shown in FIG. 1 , the primary tar separator of the embodiment of the present invention may also include a flow stabilization cylinder 3 . The steady flow cylinder 3 is located inside the housing 1, and the steady flow cylinder 3 is movably connected with the central shaft 8, and the bottom of the steady flow cylinder 3 is only open up and down.

Further, as shown in Fig. 1, the initial tar separator of the embodiment of the present invention can also include an upper umbrella surface 4 also located inside the housing 1, and the upper umbrella surface 4 is also movably connected with the central shaft 8, but located in the steady flow tube 3 below.

Further, as shown in FIG. 1 , the initial tar separator of the embodiment of the present invention can also include a lower umbrella surface 5, which is also located inside the housing 1, and the lower umbrella surface 5 is also movably connected with the central shaft rod 8, But be positioned at upper umbrella surface 4 below. That is to say, the steady flow cylinder 3 and the lower umbrella surface 5 are respectively movably connected with the central shaft rod 8 in order from top to bottom.

Further, as shown in Figure 1, the initial tar separator of the present embodiment can also include a motor 7 positioned outside the casing 1 and a slime scraper 6 positioned at the bottom of the casing 1; the bottom of the casing 1 is in the shape of an inverted cone , and the center of the bottom is provided with a slime outlet S3. The motor 7 can run continuously, or run at intervals. The upper end of the central shaft 8 protrudes from the outside of the housing 1 and is connected to the motor 7. The lower end of the central shaft 8 is located at the bottom of the housing 1 and is fixedly connected with the slime scraper 6. The central shaft 8 follows the rotation of the motor 7. The central shaft 8 Drive coal slime scraper 6 to rotate.

Wherein, the central shaft 8 runs through the housing 1 longitudinally, which can support all structures in the housing 1 in a suspended state and provide an origin for the rotatable structures. When the central shaft 8 starts to rotate with the motor 7 , the overflow weir 2 , the flow stabilization cylinder 3 , the upper umbrella surface 4 and the lower umbrella surface 5 that are movably connected with the central shaft 8 do not rotate with the central shaft 8 . The water dust scraper 12 fixedly connected to the central shaft 8 through the water pull rod 13 and the coal slime scraper 6 fixedly connected to the central shaft 8 all rotate with the central shaft 8 . As shown in FIG. 1 , the slime scraper 6 of this embodiment can be fixedly connected to the central shaft 8 through an underwater pull rod 11 .

Further, as shown in Figure 1, there is a first annular gap between the lower edge of the lower umbrella surface 5 and the side wall of the housing 1, the upper umbrella surface 4 is surrounded by the periphery of the middle part of the steady flow tube 3, and the lower edge and the shell There is a second annular gap between the side walls of the body 1, the purpose is to make the gas water after gravity sedimentation and separation of impurities squeeze out along the second annular gap, and pass between the upper umbrella surface 4 and the side wall of the shell 1 At least two connection points are connected, preferably two connection points are connected symmetrically to ensure the stability of the upper umbrella surface 4, or there can be more than two odd or even connection points, the more the connection points, the stronger the stability . The reason why the lower umbrella surface 5 is located below the upper umbrella surface 4 is to control that the tar separated from the original gas water can remain stable in a certain space in the housing 1 .

Further, as shown in FIG. 1 , the initial tar separator of the embodiment of the present invention may also include a water inlet pipe S1 and an outlet pipe S2; wherein one end of the water inlet pipe S1 extends into the inside of the steady flow cylinder 3 , and the other end extends out of the housing 1 External; 1. One end of the outlet pipe S2 extends into the bottom of the overflow weir 2, and the other end extends out of the shell 1.

Further, as shown in FIG. 1 , the initial tar separator of this embodiment may also include a tar outlet pipe S4;

The overflow weir 2, the steady flow cylinder 3, the upper umbrella surface 4 and the lower umbrella surface 5 in the initial tar separator of the embodiment of the present invention have a fixed connection relationship with each other and/or between each of them and the side wall of the housing 1 Has a fixed connection relationship. In practical applications, such a fixed connection relationship may be welding, riveting or other fixed connection relationships. The overall fixed relationship is mainly the fixed connection with the side wall of the housing 1 , supplemented by the fixed connection between them.

Optionally, the steady flow cylinder 3 in the embodiment of the present invention is a trumpet-shaped cylinder. When the original gas water is introduced into the steady flow cylinder 3 from the water inlet pipe S1, there is a certain spray force, and the horn-shaped steady flow cylinder 3 It can better buffer the corresponding injection force, so that the original gas water can drop slowly.

Further, as shown in FIG. 1 , in the primary tar separator of the embodiment of the present invention, water outlet holes 9 are provided on the top of the upper umbrella surface 4 near the periphery of the flow stabilization cylinder 3 . Because the original gas water inevitably contains light oil, the density of light oil is smaller than that of water, the light oil in the original gas water coming in from the steady flow tube 3 will float upwards, and then slowly gather in the center below the upper umbrella surface 4 , it is difficult to flow upward from the second annulus. Even if some light oil flows upward from the second annulus following the gas water, because the second annulus is located at the lower edge of the upper canopy surface 4 and is relatively low, it may mix with the tar that settles below, affecting the sedimentation effect of the tar . Therefore, in the embodiment of the present invention, the top of the upper umbrella surface 4 is provided with a water outlet 9 near the steady flow cylinder 3, so that the light oil in the gas water can be squeezed out upwards from the water outlet 9, and float to the overflow weir 2 The height of the liquid surface, together with the gas water, flows out from the outlet pipe S2 into the next process, which can further ensure the separation effect of tar. Certainly, because of the less amount of light oil, a large amount of gas water is discharged upwards from the water outlet hole 9 in fact simultaneously.

Further, in the initial tar separator of the embodiment of the present invention, the lower edge of the upper umbrella surface 4 is provided with a baffle plate upwards, because in the actual separation process, some coal dust will also settle on the upper umbrella surface 4, and the coal dust After it is too much, it will slide along the upper umbrella surface 4 to the lower edge around. If it is not blocked, it will inevitably form a countercurrent movement with the current in the second annulus, which will affect the overall settlement or separation effect.

Further, as shown in Figure 1, in the initial tar separator of the embodiment of the present invention, the lower edge of the upper umbrella surface 4 is provided with a downcomer 10 downwards, and the interception space formed by the baffle plate and the upper umbrella surface 4 and the downcomer 10 connected. The function of the downcomer 10 is to flow the coal dust settled on the upper umbrella surface 4 to the bottom of the housing 1 from the inside. The quantity of downcomer 10 is not limited, and the purpose of arranging downcomer 10 is to make the coal dust on the upper umbrella surface 4 flow to the bottom of housing 1 through downcomer 10 .

Further, the lower end of the downcomer 10 is inclined towards the direction of the central shaft 8, and the downcomer 10 is used to flow the coal dust settled on the upper canopy surface 4 to the bottom of the primary tar separator along it, from the coal slime outlet S3 discharge. In the present embodiment, the preferred solution is to incline the lower end of the downcomer 10 to the direction of the central shaft 8. Such an angle can ensure that the coal dust settled on the upper umbrella surface 4 is as far as possible towards the bottom center of the initial tar separator. Aggregated to facilitate discharge from the slime outlet S3.

Because if the downcomer 10 is vertically downward, the coal dust falling from the downcomer 10 will generally fall on the upper end of the coal slime scraper 6, which is also the bending place where the side wall of the housing 1 is connected with the cone part, and deposition is easy to occur. Affect coal slime scraper 6 to rotate. During normal operation, the coal dust can be controlled at the middle and lower position of the cone, if it is too high, it will affect the rotation of the coal slime scraper 6. Therefore, in the embodiment of the present invention, the lower end of the downcomer 10 is inclined toward the direction of the central shaft 8 . In addition, during normal operation, the coal slime scraper 6 is continuously rotating, the purpose is to gather coal dust to the center of the bottom of the cone, and when it reaches a certain amount, it will be discharged intermittently from the bottom slime outlet S3, of course, it can also be set to discharge continuously. The tar liquid level will be controlled at the upper part of the lower umbrella surface 5. If it is too high, it will affect the settlement of the gas and water coming in later, because there is a settling space between the bottom of the steady flow tube 3 and the tar liquid level. If it is too small, it will affect settlement. When the tar liquid level reaches a certain position, it starts to go out, and the lowest position needs to be controlled and cannot be lower than the lower edge of the lower umbrella surface 5; if it is lower than the lower edge of the lower umbrella surface 5, what is discharged will not be tar but gas water. The tar in the embodiment of the present invention is discharged through the tar outlet pipe S4. If continue to keep between the high position and the low position and continue to operate normally, the tar in the lower umbrella surface 5 belongs to clean clear oil.

For the primary tar separator in the embodiment of the present invention, the content further explained above is the optimal design, not the only design, which is only used to achieve a better gas-water separation effect, which is beneficial to the subsequent production process.

And the above-mentioned embodiment describes the technical solution of the present invention by including all the above-mentioned further preferred solutions as an example. In practical applications, all the above-mentioned preferred technical solutions can be combined in any combination to form optional embodiments of the present invention. This will not repeat them one by one.

The following uses the initial tar separator of the embodiment of the present invention including all the above-mentioned components as an example to describe the use process of the initial tar separator, as follows:

First, the shell 1 is filled with water first, and then the original gas water enters the steady flow cylinder 3 through the water inlet pipe S1, and naturally settles according to gravity, coal dust and tar slowly descend, and the separated gas water flows from the upper umbrella surface 4 The second annular gap between the shell 1 wall and the water outlet hole 9 on the upper umbrella surface 4 is squeezed out upwards, and when the liquid level reaches the overflow weir 2, the separated gas water flows into the overflow weir 2 from there , and flow out through the outlet pipe S2 at the bottom of the overflow weir 2 and enter the next process. Because the density of coal dust is bigger than tar, so after a period of time, then deposit coal dust on the side wall of the cone bottom of casing 1, the highest position of the deposited coal dust layer can not be higher than the highest position of coal slime scraper 6, Generally, it is controlled at the middle and lower part of the cone at the bottom of the shell. Because the density of tar is greater than the density of gas water, so above the coal dust layer is a relatively pure tar layer, the highest position of the tar layer can not be higher than the upper position of the lower umbrella surface 5. Above the tar layer is gas water. When the liquid level of tar rises to the upper position close to lower umbrella surface 5, tar is then started to be discharged from tar outlet pipe S4. Along with the discharge of tar, the tar liquid level outside the lower umbrella surface 5 in the housing 1 descends, and when the liquid level of the tar layer descends to the lower edge close to the lower umbrella surface 5, the control stops discharging tar. Because the gas water will flow from the second annulus to the overflow weir located in the center above the upper umbrella surface 4, so there may still be a part of coal dust falling on the upper umbrella surface 4, and the dust deposited on the upper umbrella surface 4 The coal dust flows along the downcomer 10 to the bottom of the primary tar separator. The motor 7 drives the central shaft 8 to rotate, and the central shaft 8 drives the coal slime scraper 6 to rotate, and the coal dust settled on the side wall of the bottom of the housing 1 is scraped up and gathered in the middle, and then from the center of the bottom of the housing 1 Position the slime outlet S3 to discharge. Along with the continuation of gas water entering and gravity natural settlement, the tar liquid level outside the lower umbrella surface 5 slowly rises again, and when rising to the upper position close to the lower umbrella surface 5, oil can be drained again. By repeating the above process, the impurities such as tar and coal dust in the original gas water can be separated.

In the initial tar separator of this embodiment, the process of filtering the floating dust and impurities on the liquid surface is as follows: when the central shaft 8 rotates clockwise, the water pull rod 13 is driven to pull the water dust scraper 12 to rotate clockwise around the central shaft 8, The water dust scraper 12 scrapes the floating dust impurities on the liquid surface to the end of the water dust scraper 12, and when the end of the water dust scraper 12 rotates to the collection bucket 14, the floating dust impurities of the water dust scraper 12 are sent into the collection bucket 14. After the floating dust and impurities are collected in the collecting tank 141 inside the housing 1 in the collecting bucket 14, they flow into the diversion bucket 142 of the collecting bucket 14 outside the housing 1, and can be discharged through the outlet 143 provided on the diversion bucket 142. The collected dust and impurities.

The initial tar separator of the embodiment of the present invention, by adopting the above scheme, can realize the separation treatment of the original gas water with impurities such as tar and coal dust, effectively separate the tar and coal dust in the gas water, and initially purify the gas The water quality provides convenience for the advanced treatment of gas water. At the same time, the initial tar separator of this embodiment can also clean up the floating dust and impurities on the gas water surface, thereby further purifying the gas water after impurity separation, further optimizing the production process of gas water, and further providing convenience for the advanced treatment of gas water .

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: It is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the various embodiments of the present invention. scope.
