Description

Technical Field

[0001] The invention relates to an industrial waste salt treatment method, in particular to an industrial waste salt treatment and energy storage method. Background Art

[0002] Industries such as petrochemicals, coal chemicals, pesticides, pharmaceuticals, and fine chemicals continuously generate large quantities of waste salts during their production processes. These waste salts primarily contain a variety of salts, including inorganic salts such as sodium, calcium, magnesium, iron, copper, aluminum, lead, zinc, chromium, cadmium, manganese, arsenic, nickel, silicon, and phosphorus. Furthermore, these industrial waste salts often contain organic pollutants, including complex components such as organic solvents, mineral oils, polymers, aromatic hydrocarbons, halogenated organic compounds, esters, ethers, alcohols, and aldehydes. Due to the highly complex composition of industrial waste salts, the presence of toxic organic compounds, and their high hardness and viscosity, their treatment is difficult, making them difficult to reuse as a resource. Consequently, they are often left in large quantities, posing a potential risk of soil and water pollution.

[0003] Advanced processing, recycling, purification, and reuse of industrial waste salt not only mitigates environmental hazards but also maximizes its economic value. Currently, only high-temperature processes are feasible for advanced processing and utilization of waste salt. Rotary kiln calcination, typically using coal or natural gas as the heat source, is commonly employed. High-temperature heating using plasma torches and arcs is also an option, but these methods consume significant amounts of electricity. Furthermore, clean, renewable energy sources such as wind and solar power, which are often unstable and intermittent, often prevent these facilities from utilizing them. Summary of the Invention

[0038] In order to keep the following description of the disclosed embodiments of the present invention clear and concise, the disclosed embodiments omit detailed descriptions of known functions and known components.

[0039] like Figure 1-6 As shown, an embodiment of the present invention provides an industrial waste salt treatment and energy storage device, comprising:

[0040] The treatment tank 1 is constructed as a cylindrical shell with an inner cavity. Currently, the treatment of waste salt by high-temperature calcination is a relatively common treatment process, which mainly uses high temperature to thermally decompose organic matter. When the waste salt is treated at high temperature, the principle of anaerobic cracking of organic matter is mainly used. Therefore, it is necessary to ensure the sealing of the entire treatment tank 1 during calcination. The upper end of the treatment tank 1 is provided with an opening for pouring the waste material to be treated. The upper side of the treatment tank 1 is matched with a sealing cover 11. A lifting control component (not shown) is provided between the sealing cover 11 and the treatment tank 1. The reactor or tank body currently uses an automatic lifting switch, which is widely used in actual production in this field. The lifting structure can adopt a variety of existing structures to realize the lifting action of the sealing cover 11. No specific statement will be made in this application.

[0041] It also includes a mobile platform 2, which is horizontally arranged in the processing tank 1. A number of heating rods 21 are fixedly arranged vertically and evenly on the lower end surface of the mobile platform 2. During the high-temperature treatment of waste salt, the waste gas generated needs to be discharged. Therefore, a gas outlet pipe 15 is fixedly connected to one side of the upper end of the processing tank 1, and the temperature inside the processing tank 1 needs to be detected to ensure the control of the temperature inside the processing tank 1. A number of temperature and pressure sensors are evenly fixed in the processing tank 1, and a controller 16 electrically connected to the number of temperature and pressure sensors is fixedly arranged outside the processing tank 1; but currently used When the electric heating rod realizes the heating effect, it needs to consume a large amount of electric energy. At present, my country's clean and renewable energy sources mainly include wind energy and solar energy, but these clean and renewable energy sources are unstable electric energy, which are all in the form of discontinuous or continuous. Therefore, the heating rod 21 in the device adopts a ceramic electric heating rod, and further, in order to ensure the full utilization of heat, the outer fixed sleeve of the treatment tank 1 is provided with an insulation sleeve 12. The device realizes the direct conversion into heat energy in the form of discontinuous or continuous, and stores it in industrial waste salt, which can keep the industrial waste salt in an ultra-high temperature state for a long time. At the same time, there will be problems when treating industrial waste salt. The heat energy that cannot be utilized can be utilized. A serpentine groove is provided on the end surface of the insulation sleeve 12 close to the treatment tank 1. A heat exchange water pipe 13 is fixedly arranged in the groove. Both ends of the heat exchange water pipe 13 pass through the insulation sleeve 12 and extend to the outside. The lower end of the heat exchange water pipe 13 is a heat exchange water pipe outlet 131. When the heat energy needs to be utilized, water is passed through the heat exchange water pipe 13 to carry away the heat energy and output steam. According to the existing waste salt high-temperature treatment process, the waste salt is generally calcined directly at high temperature in a container such as a reactor. After calcination, The waste gas is treated, but the current high-temperature treatment device either uses high-temperature gas to achieve the heating effect, which is not uniform for the heating of the waste salt and has a poor heating effect. The use of direct contact heating structures such as heating rods also has the problem of uneven contact. To address this problem, a stirring rod is generally used to achieve uniform heating. However, impurities generated during the stirring process are easy to adhere to the stirring rod, and vortices are easily formed during the rotating stirring process. Due to the centrifugal effect, a part of the solid waste salt is always attached to the inner wall of the container, and the contact with the direct heating structure is still not sufficient, resulting in poor overall heating effect.Therefore, in this device, the mobile platform 2 can move vertically, and at the same time, the mobile platform 2 can move arbitrarily in the horizontal position, and can change the heating position according to the needs, and has the function of stirring. At the same time, the heating will not be insufficient due to the single rotation action. In order to achieve the above needs and ensure the sealing of the processing tank 1, the mobile platform 2 is connected to the sealing cover 11 through a mobile component. The mobile component includes a mobile disk 31 arranged in the sealing cover 11, the mobile platform 2 is connected to the mobile disk 31, and the upper end surface of the mobile disk 31 is fixedly connected to the disk external connection member 146, and the inner wall of the sealing cover 11 is provided with a ring The limiting groove has a side T-shaped cross-section, with four sliding studs 32 evenly arranged within it. Four elastic limiting rods 33 are arranged around the movable disk 31 and connected to the movable disk 31. The ends of the four elastic limiting rods 33, which are away from the movable disk 31, extend into the limiting groove and are fixedly connected to the four sliding studs 32. In this structure, the four elastic limiting rods 33 and the sliding studs 32 can achieve a vertical limit and fixation of the movable disk, while ensuring horizontal movement of the movable disk 31 within the sealing cover 11.

[0042] In this device, it is also necessary to control the movement of the mobile platform 2, that is, to control the movement of the mobile disk 31. In order to achieve the control of the movement of the mobile disk 31 while ensuring the high sealing of the processing tank 1, the sealing cover 11 is provided with a driving assembly 14, which includes a frame 141 provided on the upper side of the sealing cover 11. The frame 141 is provided with a horizontal strip frame 142 and a strip frame 2 143. Both ends of the strip frame 142 and the strip frame 2 143 are slidably connected to the frame 141. 3 are arranged vertically and adjacent to each other, and the sliding block 144 slides simultaneously in the bar frame 142 and the bar frame 2 143. A fixing rod 145 is vertically provided on the upper side of the sealing cover 11. The upper end of the fixing rod 145 is fixedly connected to the sliding block 144, and the lower end of the fixing rod 145 is fixedly connected to the outer connecting member 146 of the connecting plate. Through the movement of the bar frame 142 and the bar frame 2 143, the sliding block 144 can be controlled to drive the fixing rod 145 to move to any position in the horizontal direction. Therefore, the frame-shaped member 141 is provided with two control components 148 for driving the bar frame 142 and the bar frame 2 143 to move. The control component 148 includes a screw 1481 arranged in the frame-shaped member 141. The two screws 1481 are arranged perpendicular to each other. A connecting block 1482 is threadedly sleeved on the screw 1481. The two connecting blocks 1482 are fixedly connected to the bar frame 142 and the bar frame 2 143 respectively. Both ends of the screw 1481 are rotatably connected to the frame-shaped member 141. Two servo motors 1483 are fixedly provided on the frame-shaped member 141 to drive the two screws 1481 to rotate respectively. When it is necessary to control the mobile platform 2 to move arbitrarily in the horizontal direction, the two servo motors 1483 are used to work, and the control bar The first-shaped frame 142 and the second-bar frame 143 respectively move within a certain stroke, which can realize the control of the movement of the fixed rod 145 to any position within the projection area of ​​the frame-shaped member 141, and then control the outer disk connection member 146 to move arbitrarily within the corresponding area. The outer disk connection member 146 drives the movable disk 31 to move horizontally within the range inside the sealing cover 11. Because the movable platform 2 is connected to the lower side of the movable disk 31, the effect of controlling the movable platform 2 to move arbitrarily is achieved. When the movable platform 2 moves, it can drive a number of heating rods 21 to move. When it moves irregularly at a certain rate, it can stir the waste salt, and can also ensure the sufficient heating effect of the waste salt, ensure the overall high waste salt treatment effect, and also ensure the sealing state of the treatment tank 1;

[0043] The heating rod 21 is easily adhered when inserted into the waste salt for heating operation. At the same time, if there are too many adhered impurities, it is easy to affect the heating effect of the heating rod 21 on the overall waste salt. A cleaning structure for the heating rod 21 is set in the device. Because the movable platform 2 in the device also needs to meet the vertical movement requirement, that is, the movable platform 2 is fixedly connected to the movable disk 31 through two symmetrically arranged multi-stage telescopic rods 22. Here, the multi-stage telescopic rod 22 adopts a telescopic rod structure that can be automatically extended and retracted. It can be driven and extended by hydraulic, pneumatic or electric means. It only needs to realize the telescopic action. This telescopic rod structure has many applications in this field and will not be elaborated here. In order to avoid high temperature affecting the telescopic effect, the telescopic rod should be subjected to high temperature resistant insulation treatment. Through the telescopic rod structure, the device realizes the function of allowing the movable platform 2 to drive several heating rods 21 to move in the vertical direction, and the vertical heating position can be controlled. In this device, the vertical direction of the movable platform 2 can be used The straight moving action realizes the cleaning effect of the heating rod 21, wherein a cleaning disc 23 is provided on the lower side of the movable platform 2, and the cleaning disc 23 is slidably sleeved on several heating rods 21, and several telescopic rods 24 are vertically and evenly provided on the upper side of the movable platform 2, and several of the telescopic rods 24 are fixedly sleeved with limit springs 25 that limit their extension and contraction. The upper end of the telescopic rod 24 is fixedly connected to the movable disc 21, and the lower end of the telescopic rod 24 is fixedly connected to the cleaning disc 23, wherein the minimum length of the multi-stage telescopic rod 22 is much smaller than the minimum length of the telescopic rod 24. When the high-temperature treatment of the waste salt inside the treatment tank 1 is completed and the treated material needs to be discharged, the heating rod 21 is moved out of the material by contracting the multi-stage telescopic rod 22. When the multi-stage telescopic rod 22 is shortened to less than the minimum length of the telescopic rod 24, the cleaning disc 23 and several heating rods 21 move relative to each other, thereby cleaning the material adhered to the heating rod 21. This cleaning structure does not affect the function of the heating rod 21 when it is inserted into the waste salt.

[0044] The method for treating and storing industrial waste salt using this device includes the following steps: first, using a multi-axis spiral pulverizer to crush the industrial waste salt and evenly distribute it in a treatment tank 1. Next, a heating rod 21 is placed in the treatment tank 1 and inserted into the crushed industrial waste salt. Intermittent electrical energy from a wind or solar power plant is converted into heat energy by the heating rod 21 and introduced into the treatment tank 1, locally heating the industrial waste salt to above 1000°C. The heating rod is then moved to another location in the treatment tank and continuously heated until all the industrial waste salt in the treatment tank is melted. During the heating process, because the treatment tank 1 is equipped with an insulation jacket 12, a discontinuous heating method can be used, allowing heating to be turned on and off at any time. The temperature can be maintained until it is output and used during peak power or heat periods. After heating to above 1000°C, all organic pollutants in the waste salt are completely decomposed under anoxic conditions. The resulting waste gas is discharged through a gas outlet pipe 15. The discharged waste gas is treated in a desulfurization and denitrification spray tower and an activated carbon adsorption device before being discharged into the atmosphere. Because the molten industrial waste salt can store heat for a long time in the heating kettle, it can be used to heat and evaporate the water in the heat exchange water pipe 13 during peak power periods to drive the steam turbine to generate electricity, or to output high-temperature steam during peak thermal periods. After cooling, the inorganic salt treated in the treatment tank 1 can be dissolved in water in a dissolution tank and then passed through a nanofiltration membrane to separate the monovalent salt from the polyvalent salt, obtaining a monovalent salt solution for industrial production.

[0045] Of course, the above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
