DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be used as limitations on the present application. As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear indication to the contrary in the context.

[0024] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0025] The multiple involved in the embodiments of the present application means greater than or equal to two. It should be noted that in the description of the embodiments of the present application, the words "first", "second", etc. are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0026] like Figure 1 As shown, the industrial salt slag processing equipment provided in the embodiment of the present application includes: a crusher 1, an air separation device 10, a predissolver 2 and a salt tank 3. Among them, the crusher 1 includes a crusher feed port 104 and a crusher discharge port 105, and the predissolver 2 includes a predissolver feed port 201, a predissolver discharge port 203 and a predissolver gas outlet 202. In this way, after the industrial salt slag is cooled, it enters the crusher 1 through the crusher feed port 104 for crushing, and the crushed industrial salt slag is discharged through the crusher discharge port 105.

[0027] The pulverizer discharge port 105 is connected to the predissolver feed port 201, and the air separation device 10 is located inside the pulverizer 1, so that the crushed industrial salt slag is screened by the air separation device 10 and then transported to the predissolver 2 through the pulverizer discharge port 105. In this way, small particles of industrial salt slag can be screened to enter the predissolver 2, so that small particles of industrial salt slag can be dissolved faster, thereby increasing the dissolution rate of the industrial salt slag.

[0028] In order to ensure the accuracy of industrial salt slag particle screening, Figure 1As shown, the crusher discharge port 105 is higher than the crusher feed port 104, the crushing assembly of the crusher 1 is located at the bottom of the crusher 1, and the air separation device 10 is close to the crusher discharge port 105, so that in the process of crushing and screening of industrial salt slag in the crusher 1, small particles of industrial salt slag can first move a distance towards the direction of the air separation device 10 and then pass through the screening of the air separation device 10. Large particles of industrial salt slag fall and are crushed again in this process, which ensures the adequacy of the industrial salt slag crushing and the accuracy of particle screening, and further improves the dissolution rate of the industrial salt slag.

[0029] like Figure 1 As shown, the pre-dissolver outlet 203 is connected to the feed port of the salting tank 3, and a spray assembly 210 is provided in the pre-dissolver 2. The spray assembly 210 is provided between the pre-dissolver gas outlet 202 and the pre-dissolver feed port 201, and the pre-dissolver gas outlet 202 is located at the top of the pre-dissolver 2. In this way, after the industrial salt slag enters the pre-dissolver 2, the industrial salt slag is pre-dissolved under the spraying action of the spray assembly 210, so that the pre-solution formed after the pre-dissolution enters the salting tank 3 for dissolution, so that the pre-solution of the industrial salt slag can be dissolved faster and more fully in the salting tank 3, thereby improving the dissolution speed and dissolution effect, and improving the processing efficiency of the industrial salt slag.

[0030] In order to further improve the predissolution effect of industrial salt slag in the predissolver 2, as Figure 1 As shown, the bottom of the predissolver 2 is a conical section, and the small end of the conical section is located in the salt tank 3, so that the pre-solution formed by the predissolver 2 can directly enter the salt tank 3 to reduce external pollution. The predissolver discharge port 203 is located at the small end of the conical section, and the predissolver feed port 201 is higher than the conical section, so that the industrial salt slag can spirally move along the inner wall of the conical section after entering the interior of the predissolver 2, so that the water sprayed by the spray assembly 210 can be fully integrated with the industrial salt slag, further improving the dissolution effect of the industrial salt slag.

[0031] In some embodiments, the spray assembly 210 is configured into two groups, and fillers are disposed under each group of spray assemblies 210 to improve the gas-liquid fusion efficiency during the spraying process, achieve better dissolution of dust in the industrial salt slag, and further improve the predissolution effect of the industrial salt slag in the predissolver 2.

[0032] Since a large amount of mist will appear during the operation of the spray assembly 210 in the pre-dissolver 2 , a built-in demisting device is provided on the top of the pre-dissolver 2 to achieve preliminary demisting of the pre-dissolver 2 .

[0033] like Figure 1As shown, the industrial salt slag treatment equipment provided in the embodiment of the present application also includes a demister 6 and an induced draft fan 7, the demister 6 includes a demister air inlet 601, a demister water inlet and a demister air outlet 602, the pulverizer 1 also includes a pulverizer air inlet 101; the demister air inlet 601 is connected to the predissolver air outlet 202, the demister air outlet 602 is connected to the air inlet of the induced draft fan 7, and the air outlet of the induced draft fan 7 is connected to the pulverizer air inlet 101. In this way, under the action of the induced draft fan 7, the industrial salt slag crushed in the pulverizer 1 is blown into the predissolver 2, and the gas entering the predissolver 2 enters the demister 6 through the predissolver outlet 202, so that the gas and the industrial salt slag are separated in the predissolver 2, and the predissolver 2 is defogged under the action of the demister 6 to ensure the stable operation of the predissolver 2, and then the gas flows back to the induced draft fan 7 through the demister outlet 602, so that the gas passes through the induced draft fan 7, the pulverizer 1, the predissolver 2, the demister 6, and the induced draft fan 7 in sequence, forming a closed circulation system, reducing dust emission pollution and reducing pollution to the outside air.

[0034] Since the pulverizing process of the pulverizer 1 generates a lot of heat, in order to prevent the gas entering the pulverizer 1 from being liquefied by the induced draft fan 7, a circulating cooling water system is provided in the pulverizer 1, such as Figure 1 As shown, the pulverizer 1 includes a circulating cooling water inlet 102 and a circulating cooling water return port 103, the circulating cooling water inlet 102 and the circulating cooling water return port 103 are connected to a circulating cooling water pipe, and the circulating water cooling pipe is located inside the pulverizer 1 to cool the inside of the pulverizer 1 to prevent the gas from liquefying inside the pulverizer 1.

[0035] In actual situations, in order to ensure the working efficiency of the induced draft fan 7, the air outlet of the induced draft fan 7 is also connected to an exhaust venting pipeline, on which an eighth control valve 18 and a filter 9 are provided. When the efficiency of the induced draft fan 7 is reduced, the eighth control valve 18 is opened to allow the induced draft fan 7 to be emptied after passing through the filter 9, thereby ensuring the stable operation of the induced draft fan 7.

[0036] In order to further ensure the separation effect of gas and industrial salt slag in the predissolver 2, a flap valve is provided at the predissolver outlet 203 to achieve air-locking discharge, further ensuring the separation effect of gas and industrial salt slag, so as to ensure the dissolution effect of industrial salt slag.

[0037] Since the continuous operation of the demister 6 will cause a large internal pressure difference, it is necessary to flush the inside of the demister 6 with water through the demister water inlet. Specifically, Figure 1As shown, the demister water inlet includes a first demister water inlet 604 and a second demister water inlet 605, and all-round flushing of the inside of the demister 6 is achieved through the two water inlets, thereby ensuring the flushing effect; the demister 6 also includes a demister water outlet 603, and the demister water outlet 603 is connected to the salt tank 3, so that the liquid generated after flushing the demister 6 is directly discharged into the salt tank 3, without the need for additional treatment, thereby simplifying the process.

[0038] Since a large amount of dust will be generated during the crushing process of the industrial salt slag by the pulverizer 1, the dust will be blown into the interior of the pre-dissolver 2 under the action of the induced draft fan 7. In order to further ensure the separation effect of the gas and the industrial salt slag in the pre-dissolver 2 and increase the dissolution rate of the dust, Figure 1-Figure 2 As shown, the pulverizer discharge port 105 is connected to the predissolver feed port 201 through a venturi tube 8. A nozzle 801 is provided at the throat of the venturi tube 8, and the nozzle 801 includes an air inlet and a water inlet. Compressed air and produced water enter the nozzle 801 through the air inlet and the water inlet respectively. In this way, the flow rate of the gas from the induced draft fan 7 increases when passing through the throat of the venturi tube 8, so that a negative pressure is generated at the throat, thereby sucking in the produced water and compressed air, so that the produced water and compressed air form mist, and the dust and the mist are merged to form particles, so that the dust particles entering the predissolver 2 can be better predissolved under the spraying action of the spray assembly 210, thereby improving the separation effect of the gas and industrial salt slag in the predissolver 2 and increasing the dissolution rate of the dust.

[0039] It should be noted that the mist formed in the venturi tube 8 can be water mist or dry mist, which is collectively referred to as mist herein, and the embodiments of the present application do not limit this.

[0040] In order to further improve the fusion effect of the mist and dust in the Venturi tube 8, the nozzle 801 is rotatably connected to the Venturi tube 8 through a universal joint, thereby expanding the range of the mist sprayed by the nozzle 801 and achieving full fusion of the mist and dust; and, at the ejection end of the nozzle 801, vibration is used to cause a secondary collision between water and compressed air to make the atomization more complete, thereby improving the fusion effect of the mist and dust.

[0041] The industrial salt slag pre-dissolved by the pre-dissolver 2 enters the salt tank 3 for stirring and dissolving. The salt tank 3 is provided with a stirring device 310. The discharge port of the salt tank 3 is connected with a shearing machine 4 and a delivery pump 5. Specifically, the discharge port of the salt tank 3 is connected with the feed port of the shearing machine 4, the discharge port of the shearing machine 4 is connected with the feed port of the delivery pump 5, the discharge port of the delivery pump 5 is connected with the reflux port of the salt tank 3, and a first control valve 11 is provided between the discharge port of the salt tank 3 and the feed port of the shearing machine 4. When the brine in the salt tank 3 reaches the first liquid level, the first control valve 11 is opened, so that the brine in the salt tank 3 enters the shearing machine 4 for shearing, so that the undissolved particles in the brine are re-ground, and the sheared brine flows back to the salt tank 3 through the delivery pump 3 for stirring and dissolving, so as to improve the dissolution effect of the industrial salt slag in the salt tank 3.

[0042] The discharge port of the delivery pump 5 is connected to the first delivery pipeline 21 and the second delivery pipeline 22. The first delivery pipeline 21 connects the discharge port of the delivery pump 5 and the reflux port of the salt tank 3, and a second control valve 12 is provided on the first delivery pipeline 21. When the brine in the salt tank 3 reaches a first liquid level, the second control valve 12 opens to allow the sheared brine to reflux; the second delivery pipeline 22 connects the discharge port of the delivery pump 5 and the subsequent equipment located downstream of the industrial salt slag treatment equipment provided in this embodiment, and a third control valve 13 is provided on the second delivery pipeline 22. When the brine in the salt tank 3 reaches a second liquid level, the second control valve 12 reduces the opening and opens the third control valve 13 to allow the dissolved brine to flow into the subsequent equipment.

[0043] In order to further ensure the dissolution effect of the industrial salt slag in the salt tank 3, an anti-accumulation baffle is set on the inner wall of the salt tank 3, and a serrated arc-shaped protrusion is set on the anti-accumulation baffle. In this way, during the stirring process of the stirring device 310, the brine in the salt tank 3 can reduce laminar flow and increase turbulence under the action of the anti-accumulation baffle, so that the industrial salt slag can be fully dissolved in the salt tank 3, thereby improving the dissolution effect and dissolution efficiency.

[0044] In order to ensure the water supply demand of the components in the industrial salt slag treatment equipment provided in this embodiment, the industrial salt slag treatment equipment is connected to external production water, and the production water is connected to the first water pipeline 31, the second water pipeline 32, the third water pipeline 33 and the fourth water pipeline 34.

[0045] The first water pipeline 31 is connected to the water inlet of the nozzle 801 in the venturi tube 8, and a fourth control valve 14 is provided on the first water pipeline 31. When the venturi tube 8 is in operation, the fourth control valve 14 is opened to allow the produced water to enter the nozzle 801 and form mist with the compressed air.

[0046] The second water pipeline 32 is connected to the spray assembly 210 in the predissolver 2, and a fifth control valve 15 is provided on the second water pipeline 32. During the operation of the predissolver 2, the fifth control valve 15 is opened, and production water is sprayed out through the spray assembly 210 to achieve predissolution of industrial salt slag.

[0047] The third water pipeline 33 is connected to the water inlet of the demister 6 , and a sixth control valve 16 is provided on the third water pipeline 33 . When the pressure difference inside the demister 6 is large, the sixth control valve 16 opens to flush the demister 6 .

[0048] The fourth water pipeline 34 is connected to the water inlet of the salt tank 3, and the water inlet of the salt tank 3 is located at the upper end of the salt tank 3. The fourth water pipeline 34 is provided with a seventh control valve 17. After the industrial salt slag enters the interior of the salt tank 3 after pre-dissolution, the seventh control valve 17 is opened to allow production water to enter the salt tank 3 to dissolve the industrial salt slag.

[0049] The fifth water supply pipeline 35 is connected to the flushing port of the salt tank 3, and the flushing port of the salt tank 3 is located at the bottom of the salt tank 3, and the fifth water supply pipeline 35 is provided with a ninth control valve 19. After the salt tank 3 stops working, when there is material deposited at the bottom of the salt tank 3, the ninth control valve 19 is opened, so that the production water can be flushed from the bottom of the salt tank 3 to flush the deposited material and reduce material deposition.

[0050] When the industrial salt slag treatment equipment provided in the embodiment of the present application is working, first, the induced draft fan 7 and the pulverizer 1 are turned on in sequence to form a closed circulation system to ensure the normal operation of each component. The cooled industrial salt slag enters the pulverizer 1 through the pulverizer feed port 104 for pulverization. Under the action of the air separation device 10, the industrial salt slag is pulverized into small particles and the dust enters the venturi tube 8 through the pulverizer discharge port 105, so that the dust is fused with the mist formed by the venturi tube 8. The formed dust particles and industrial salt slag particles enter the predissolver 2 and are pre-dissolved under the action of the spray component 210. The pre-dissolved industrial salt slag enters the salt tank 3 through the predissolver discharge port 203 and is dissolved and stirred by the stirring device 310. When the brine in the salt tank 3 reaches a first liquid level, the brine in the salt tank 3 is sheared by the shearing machine 4 and refluxed to the salt tank 3 through the delivery pump 5 for redissolution. When the brine in the salt tank 3 reaches a second liquid level, the brine in the salt tank 3 is delivered to the downstream subsequent equipment by the delivery pump 5. In this way, the dissolution speed and dissolution effect of industrial salt slag are improved, and the processing efficiency of industrial salt slag is improved.

[0051] like Figure 3 As shown, the embodiment of the present application also provides an industrial salt slag treatment method, comprising: Crushing industrial salt slag and air separation of the crushed industrial salt slag; The industrial salt slag selected by wind enters the pre-dissolver; Spraying water onto the industrial salt slag entering the predissolver to predissolve it and form a pre-solution; The pre-solution enters into a salt tank, and the pre-solution in the salt tank is stirred to form salt water.

[0052] The industrial salt slag is crushed and the crushed industrial salt slag is air-selected, and the air-selected industrial salt slag enters the pre-dissolver. The industrial salt slag treatment method also includes: The industrial salt slag selected by wind enters the venturi tube, and the nozzle on the venturi tube sprays water and compressed air to the industrial salt slag; The industrial salt slag passes through the venturi tube and enters the predissolver.

[0053] When the liquid level of the salt tank is higher than the first liquid level, the salt water discharged from the salt tank is sheared, and the sheared salt water flows back to the salt tank; When the liquid level of the salting tank is higher than the second liquid level, the brine discharged from the salting tank enters the subsequent downstream process of industrial salt slag treatment.
