Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of waste incineration, and in particular to a device and method for combined incineration treatment of saline wastewater and waste gas. Background Art
[0002] The specific composition of industrial waste salt varies depending on its source, but it usually contains a large amount of organic matter that is difficult to separate, tends to release strong irritating odors and is even highly toxic. The pharmaceutical industry mainly produces waste gas and saline wastewater in the production process, with large emissions and a wide range of organic matter concentrations and types, including benzene, toluene, ethanol, ethyl acetate, hydrogen chloride, etc.
[0003] In the process of waste salt disposal, common treatment methods include physical treatment, chemical treatment, biological treatment and membrane separation technology. Physical treatment involves phase separation, precipitation, filtration, incineration and other steps, aiming to remove solid particles and suspended matter in waste salt; chemical treatment promotes the precipitation or coagulation of organic matter and heavy metal ions by adding chemical agents such as aluminum sulfate and polyaluminum chloride; biological treatment uses microorganisms to degrade organic matter and oxidized salts; membrane separation technology further removes organic components in waste salt and dissolves internal particles through reverse osmosis, nanofiltration and other technical means. For the treatment of waste salt, it also involves evaporation and salt separation process, which requires analysis of the composition of the waste salt solution, calculation and control of the salt separation temperature and salt-nitrogen ratio based on the mass percentage and solubility of the inorganic salt, and precise control of the endpoint concentration of each evaporation. In some cases, if the content of a certain inorganic salt in the waste salt solution has a large advantage, it can be considered to separate and recover the component by direct evaporation and crystallization. However, these conventional treatment technologies mainly focus on the treatment of saline wastewater, while the treatment of waste gas usually involves more complex technologies and process flows. Therefore, in the face of complex waste salt disposal scenarios, most waste salt treatment technologies tend to only treat either waste gas or saline wastewater, with a single use occasion, which greatly increases the treatment cost. In addition, large pharmaceutical companies often need to treat large quantities of waste salt, and the above technologies often have problems such as high disposal costs, large construction costs, low waste salt treatment efficiency, and low intelligence level.
[0004] The incineration of waste salt is an important waste salt treatment technology. The organic matter in the waste salt is decomposed by high temperature to achieve harmless and resource utilization of the waste salt. The main process of waste salt incineration is to heat the waste salt to a high temperature, usually above 800°C, so that the inorganic salt melts and flows into the bottom of the furnace, while the organic matter volatilizes and decomposes at high temperature. This method can effectively remove the organic matter in the waste salt, while recovering the inorganic salt to achieve resource utilization of the waste salt. However, incineration treatment requires a lot of energy to increase the incineration temperature, the energy consumption is high, and the heating process in the furnace is slow, the heat utilization rate is low, and in addition, the waste salt after high temperature treatment is deposited on the bottom and wall of the furnace body, which will have a great impact on the system pipelines, equipment and waste salt treatment quality, and reduce the service life of the equipment and the treatment yield. Each maintenance and cleaning requires a lot of manpower and material resources, and the recovery and treatment cycle is long, which delays normal operation. Therefore, in order to ensure the efficient and stable incineration of waste salt, it is necessary to optimize and improve the incineration treatment device and working method.
[0005] The existing patent with publication number CN115751342A discloses a combined incineration device for acrylonitrile waste gas and waste liquid, comprising: a burner for treating fuel and high calorific value waste liquid; a high-temperature reduction zone for treating high calorific value waste liquid and a small amount of low calorific value waste water, and configured with preheated combustion air or a small amount of preheated waste gas; a low-temperature reduction zone for treating low calorific value waste water, and configured with preheated combustion air or a small amount of preheated waste gas; a high-temperature mixer, provided with a preheated air distributor, a preheated waste gas distributor, and an ammonia distribution pipe; a high-temperature oxidation zone, providing space for upstream reduced flue gas or waste gas to undergo chemical reactions; a medium-temperature mixer, provided with a normal-temperature air distributor, a preheated waste gas distributor, and an ammonia distribution pipe; a low-temperature oxidation zone, providing space for upstream flue gas or waste gas to undergo chemical reactions; a low-temperature mixer, provided with a normal-temperature air distributor; a solid salt temperature adjustment zone, providing space for upstream flue gas cooling and uniformly distributing flue gas flow rate, so as to achieve the purpose of controlling fuel-type NOx, with a longer flue gas residence time and a better mixing effect.
[0006] However, the above invention does not perform diversion treatment according to the concentration of exhaust gas and waste water, and the degree of refinement is low. The combustion chamber cannot adjust the chamber size and cannot adapt to exhaust gas and waste water of different concentrations and flow rates.

[0044] Among them, the filter layers are arranged axially at equal intervals inside the activated carbon filter assembly 3, and a sedimentation port 3-2 is provided outside each filter layer for replacing the filter material, and visible impurities can also be separated and discharged.

[0049] Example 3 Reference Figure 1 to Figure 8 , which is the third embodiment of the present invention, and this embodiment is based on the previous embodiment.
[0050] Specifically, the telescopic device 25 includes a slide 251 that penetrates the outer wall of the incinerator 1, a positioning cover 252 is provided outside the slide 251, a connecting rod 253 is slidably provided inside the slide 251, a bracket 254 is fixedly provided on the outer wall of the positioning cover 252, and a sliding rod 255 is provided on the outer wall of the bracket 254.
[0051] Among them, a lifting sleeve 256 is slidably provided on the sliding rod 255, and the lifting sleeve 256 is fixedly connected to the connecting rod 253. One end of the connecting rod 253 penetrates into the incinerator 1 and is fixedly connected to the flow equalizing orifice plate 23, so that when the lifting sleeve 256 is raised or lowered, the flow equalizing orifice plate 23 is driven to rise and fall through the connecting rod 253.
[0052] Among them, during the up and down movement of the flow equalizing orifice plate 23, not only the size of the combustion chamber 18 will be changed according to the amount of exhaust gas to improve the combustion efficiency, but also the inner wall of the combustion chamber 18 of the incinerator 1 will be rubbed to scrape and remove the impurities attached to the inner wall of the combustion chamber 18 after combustion. The greater the exhaust gas intake, the greater the scraping frequency to prevent impurities from accumulating and agglomerating.
[0053] Preferably, an impeller 257 is rotatably provided in the exhaust gas inlet 26 - 1 , a rotating shaft 258 is fixedly provided at the center of the impeller 257 , and the rotating shaft 258 rotates and penetrates outside the exhaust gas inlet 26 - 1 and is provided with an eccentric fan 259 .
[0054] More preferably, the slide bar 255 is arranged parallel to the axial direction of the incinerator 1, the bracket 254 is a rectangular frame, the connecting rod 253 slides through the positioning cover 252 and is sealed therewith to prevent the heat and waste water and exhaust gas from escaping, and the other end of the rotating shaft 258 is meshed with the outer wall of the annular spray assembly 26 through a bevel gear, so that when the rotating shaft 258 rotates, it can also drive the annular spray assembly 26 to rotate on the inner wall of the incinerator 1, so as to achieve uniform spraying of the waste liquid, fully and evenly mix it with the exhaust gas, and improve the combustion efficiency.
[0055] Among them, the outer wall of the sliding rod 255 is also fixedly engaged with a fixing rod 2511, and the fixing rod 2511 is fixedly connected to the outer wall of the incinerator 1. The fixing rod 2511 is vertically provided with a support rod 2512, and an amplitude modulation rod 2513 is rotatably provided on the support rod 2512. The amplitude modulation rod 2513 is parallelly provided with an amplitude modulation groove 2514, and a slider 2515 is slidably provided in the amplitude modulation groove 2514.
[0056] Preferably, a pull rod 2516 is provided on the end face of the slider 2515, a swing arm is rotatably provided in the lifting sleeve 256, an arc groove is provided on the swing arm, and a cylinder 2517 is provided at the end of the amplitude modulation rod 2513, and the cylinder 2517 is slidably provided on the arc groove.
[0057] The rotation speed of the impeller 257 is related to the exhaust gas flow rate at the exhaust gas inlet 26-1, so the faster the exhaust gas flow rate, the faster the annular spray assembly 26 rotates. Among them, the arc groove and the swing trajectory of the swing arm do not overlap, so when the cylinder 2517 moves with the swing arm, the fulcrum position of the arc groove itself during rotation and swinging changes, thereby changing the lifting amplitude of the lifting sleeve 256. The larger the lifting amplitude, the larger the scraping range, and the maximum and minimum values of the internal space of the combustion chamber 18 also change accordingly.
[0058] Preferably, the first heat storage chamber 19 and the second heat storage chamber 20 are connected with a first branch pipe 2518 and a second branch pipe 2519 respectively, and the first branch pipe 2518 and the second branch pipe 2519 are respectively provided with a connecting pipe 2521, and the two connecting pipes 2521 are arranged in parallel.
[0059] A floating ball is slidably disposed inside the connecting tube 2521 , and a rack 2523 is slidably disposed on the outer wall of the connecting tube 2521 . One end of the rack 2523 slides through the connecting tube 2521 and is fixedly connected to the outer wall of the floating ball.
[0060] The rack 2523 is sealed to the connecting pipe 2521 to prevent gas or liquid leakage. The floating ball is made of heat-resistant rubber. When the temperature in the primary heat storage chamber 19 and the secondary heat storage chamber 20 increases, the gas expands and pushes the floating ball toward one of the heat storage chambers.
[0061] More preferably, the two racks 2523 are meshed with the gear 2524 at the same time. The gear 2524 is provided with a balance bar 2525 rotatably axially. An inclined block 2526 is provided at one end of the balance bar 2525 . The inclined block 2526 slides through the pull rod 2516 .
[0062] The inclined block 2526 is a parallelogram, and a parallelogram groove is also provided in the pull rod 2516, so that when the balance bar 2525 moves up and down, the pull rod 2516 is driven to move left and right, thereby adjusting the swinging and floating of the swing arm.
[0063] Preferably, when the temperatures in the primary heat storage chamber 19 and the secondary heat storage chamber 20 change synchronously, the two floating balls move up and down in the same proportion, thereby synchronously driving the gear 2524 to rotate. When there is a temperature difference between the two, the floating ball on the side with higher temperature moves more greatly, so that the rack 2523 on this side descends more greatly, driving the gear 2524 to roll downward along the rack 2523 on the other side for a distance, and at the same time moves downward through the balance rod 2525, driving the pull rod 2516 to move outward, so that the swing amplitude of the swing arm changes.
[0064] It should be noted that, in the present embodiment, the annular spray assembly 26 is also provided with an upwardly directed nozzle, so that when the swing amplitude of the swing arm increases, the waste liquid can also be sprayed upward to spray and cool the equalizing orifice plate 23 connected to the primary heat storage chamber 19, thereby lowering the temperature of the connected heat storage chambers, reducing the temperature difference, and preventing damage to the heat storage body.
[0065] Example 4 Reference Figure 1-Figure 18 , which is the fourth embodiment of the present invention, and this embodiment provides a method for treating saline wastewater and waste gas by combined incineration, and the method is implemented based on the above-mentioned device for treating saline wastewater and waste gas by combined incineration.
[0066] Specifically, a method for treating salt-containing wastewater and waste gas by combined incineration includes: the waste gas is monitored and diverted by a first concentration sensor 7, and low-concentration waste gas is pumped into an activated carbon filter assembly 3 by a second fan 5. The lower side wall of the activated carbon filter assembly 3 is provided with an air supply port 3-1 and a filter mesh is provided radially to preliminarily screen out large particles of impurities visible in the waste gas. The waste gas forms an upward flow field inside, and passes through a primary filter layer 3-8, whose surface is paved with macroporous activated carbon 3-8a; a secondary filter layer 3-7, whose surface is paved with transitional pore activated carbon 3-7a; a tertiary filter layer 3-6, whose surface is paved with microporous activated carbon 3-6a. The filter layer is a grid structure, which can be used as a diverter plate to guide the waste gas to flow upward, guide the waste gas to form an upward circulation, a uniform flow field, and improve the filtering efficiency of the gas. The waste gas coming out of the waste gas outlet 3-3 enters the zeolite rotor molecular sieve assembly 2 through the adsorption fan 2-4, and after the organic adsorption is completed, it is discharged after the third concentration sensor 11 monitors and meets the standard; Another part of the high-concentration exhaust gas is pumped by the first fan 4 through the exhaust gas ring pipe and directly sent into the combustion chamber 18 in the incinerator 1. At the same time, the burner 16 sprays the combustion aid to assist the incineration of the waste salt. After the incineration and purification is completed, the exhaust gas flows upward from the equalizing orifice plate 23 and enters the primary heat storage chamber 19 and the secondary heat storage chamber 20 in turn, and exchanges heat with the phase change heat storage body 20-1 to complete the heat storage process.
[0067] Most of the exhaust gas finally enters the gas storage chamber 17 at the top of the incinerator 1 through the guide orifice plate 24, and is then discharged after being monitored by the fourth concentration sensor 12 to meet the standard; the other part of the exhaust gas enters the desorption chamber 2-1 through the desorption fan 2-3 to desorb the zeolite rotor molecular sieve component 2, and after desorption is completed, it circulates through the exhaust gas ring pipe into the combustion chamber 18 for incineration purification treatment.
[0068] The organic wastewater at the other end is monitored and diverted by the second concentration sensor 8, and the organic components are pumped from high to low by the water pump 6, and enter the first-level heat storage chamber 19 and the second-level heat storage chamber 20 through the wastewater inlet pipe 34, and pass through the heat storage body to complete preheating, and then flow downward into the annular spray assembly 26 and evenly sprayed into the combustion chamber 18 until it is purified and discharged after being monitored by the fifth concentration sensor 13 to meet the standards.
[0069] The first temperature sensor 28 and the second temperature sensor 29 are deeply inserted into the upper and lower parts of the side of the first heat storage chamber 19, respectively. Similarly, the third temperature sensor 30 and the fourth temperature sensor 31 are deeply inserted into the upper and lower parts of the side of the second heat storage chamber 20, respectively. The four groups of temperature sensors are connected to the control unit. When the temperature difference between the first temperature sensor 28 and the second temperature sensor 29 (or the third temperature sensor 30 and the fourth temperature sensor 31) exceeds 100°C, in order to prevent the phase change heat storage body 20-1 from being damaged, the flow rate of the water pump 6 is increased to enable the wastewater to quickly pass through the wastewater inlet pipe 34 and complete the heat exchange, thereby reducing the temperature difference. Otherwise, the flow rate of the water pump 6 is reduced.
