Description

Technical Field

[0001] This invention relates to the field of industrial waste liquid incineration equipment technology, specifically to an industrial waste liquid incineration equipment and incineration method. Background Technology

[0002] With the rapid development of industry, the scale of industries such as chemicals and electronics is constantly expanding, and the amount of hazardous waste generated is also increasing year by year. Hazardous waste is diverse, existing in various forms such as solid, liquid, semi-solid, and solid-liquid mixtures, among which the amount of liquid hazardous waste generated is increasing. Currently, the hazardous waste incineration industry typically filters waste liquid through multiple stages before using centrifugal pumps, diaphragm pumps, gear pumps, etc., to transport it to waste liquid spray guns for atomization and incineration. Our company also uses this waste liquid spraying incineration method, but we have encountered many problems during operation.

[0003] First, because liquid hazardous waste typically possesses characteristics such as strong corrosivity, toxicity, volatility, and reactivity. The liquid is not only volatile, but also contains a large amount of impurities, which leads to problems such as easy clogging of filters and frequent cleaning of filters, high pump failure rate and short replacement and maintenance cycle in traditional waste liquid spraying systems that use pumps as the power source. Secondly, because the waste liquid contains a high amount of impurities, the waste liquid in the traditional waste liquid tank is easily clogged by the filter and pump after being stirred and homogenized, and may even cause frequent damage to the pump. Therefore, the traditional waste liquid incineration system usually does not adopt waste liquid homogenization measures. However, the key to waste liquid incineration is atomization. Excessive viscosity will lead to poor atomization effect. Therefore, the homogenization process is very important. Finally, traditional viscosity control requires manual sampling, laboratory analysis, and then a decision on whether to add a reagent. This method has a certain lag, and the timed and quantitative extensive addition can easily lead to reagent waste. Therefore, an industrial waste liquid incineration device and incineration method are proposed. Summary of the Invention

DETAILED DESCRIPTION

[0019] In the description of the present application, it should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. The embodiments of the present application will be described in detail below with reference to the drawings.

[0020] Example 1 Please refer to Figures 1 to 11The present invention preferably provides the following technical solution: an industrial waste liquid incineration device, comprising: a support 111, a nitrogen supply mechanism 112 assembled with the support 111; and a pressure tank mechanism disposed on one side of and connected to the nitrogen supply mechanism 112, wherein the nitrogen supply mechanism 112 uses nitrogen as a power source to transport and burn the waste liquid; the pressure tank mechanism includes a first support rod 113, a tank body 114 fixed to the first support rod 113, a liquid inlet pipe 118 disposed on one side of the tank body 114 for the waste liquid to enter the tank body 114; and a coupled stirring assembly 115 and a reagent dispensing assembly 116 respectively disposed in the middle and on the side wall of the tank body 114, wherein, when the viscosity of the waste liquid is too high, the coupled stirring assembly 115 adaptively senses and drives the reagent dispensing assembly 116 to add surfactant to the tank body 114 to reduce the viscosity of the waste liquid; and also includes a spray pipe 120 disposed at the bottom of the tank body 114 for the outflow and spraying of the waste liquid.

[0021] Because liquid hazardous waste typically possesses characteristics such as strong corrosivity, toxicity, volatility, and reactivity, and also contains a significant amount of impurities, traditional waste liquid incineration systems using pumps as the power source suffer from numerous problems. These include frequent filter clogging requiring cleaning, high pump failure rates, short replacement and maintenance cycles, easy clogging of spray guns leading to poor atomization, high safety risks, and waste liquid stratification affecting the incineration process. In particular, after the waste liquid is stirred and homogenized, it is extremely easy to clog filters and pumps, even causing frequent pump damage. Therefore, traditional waste liquid incineration systems usually do not employ waste liquid homogenization measures, and the outlet pipe of the waste liquid tank is generally about 30 cm from the bottom of the tank, resulting in the waste liquid in the tank not being completely incinerated. When the next batch of waste liquid enters the tank, there may be mutual reactions. To address these issues, this application organically couples three functions—nitrogen delivery, online viscosity monitoring, and automatic addition of viscosity-reducing reagents—to form an intelligent, efficient, and safe waste liquid treatment system. Specific examples Figure 1 , 2 As shown in Figures 3 and 4; First, this application uses high-pressure nitrogen instead of a pump as a power source for waste liquid spraying and burning, eliminating the pump, which is prone to damage and clogging, thus significantly reducing maintenance and operating costs. It also avoids the hassle of frequently cleaning or replacing pipes and nozzles due to blockages, extending the service life of the equipment and reducing maintenance costs. In addition, using nitrogen as a power source, the entire process is carried out in an inert atmosphere, which is safer than using a pump, especially for corrosive and flammable waste liquids. Furthermore, the inert nature of nitrogen ensures a smooth drive. Secondly, the key of waste liquid incineration lies in atomization, and too large viscosity can result in poor atomization effect, large liquid drops, insufficient combustion, and harmful substances such as black smoke, therefore, the middle and side wall of the tank body 114 are respectively equipped with a coupling stirring assembly 115 and a reagent filling assembly 116, when the viscosity of the waste liquid is too large, the coupling stirring assembly 115 can adaptively sense and drive the reagent filling assembly 116 to fill surfactant into the tank body 114, so as to reduce the viscosity of the waste liquid, and this design can overcome the hysteresis problem that the traditional viscosity control needs manual sampling, laboratory analysis, and then decides whether to add reagent, the "coupling stirring assembly 115" of the device is equivalent to an online real-time viscosity sensor, which can instantly sense the rheological property change of the waste liquid in the tank body 114, and the reagent filling assembly 116 is an execution component, and the high cooperation of the two can automatically add surfactant according to the viscosity of the waste liquid, so as to ensure that the waste liquid can always maintain excellent atomization state when being sprayed and burned, thereby improving the combustion efficiency, ensuring that the waste liquid is completely decomposed to reach the environmental protection emission standard, compared with the time-based and quantitative extensive addition, the device only adds surfactant "when needed", realizes accurate and on-demand addition of reagent, avoids waste of reagent, and reduces operation cost.

[0022] Embodiment 2 As another embodiment of the application, the coupling stirring assembly 115 comprises an inner shaft 1151 rotatably installed in the middle of the tank body 114, wherein one end of the inner shaft 1151 penetrates through a first through hole opened in the top of the tank body 114 and is fixed with the output end of a driving motor 1159 arranged on the top of the tank body 114, the other end of the inner shaft 1151 is aligned with the liquid spraying pipeline 120, a transmission groove 1152 is opened in the middle of the inner shaft 1151, and an outer sleeve 1153 is arranged in the transmission groove 1152, and a sealed interlayer is formed between the outer sleeve 1153 and the inner shaft 1151, and the sealed interlayer is filled with viscous hydraulic oil, a first coupling plate 1155 and a second coupling plate 1154 are coupled on the opposite sides of the inner shaft 1151 and the transmission groove 1152 and are arranged in the interlayer, and a stirring plate 1156 is arranged in the outer periphery of the outer sleeve 1153 in a ring shape, which is used for continuous stirring of the waste liquid, and a rotating speed sensor is arranged between the inner shaft 1151 and the outer sleeve 1153 and is used for detecting the speed of the outer sleeve 1153, when the rotating speed sensor senses the sudden change of the differential speed of the inner shaft 1151 and the outer sleeve 1153, the viscosity of the waste liquid is large, and the trigger condition of the reagent filling assembly 116 for filling surfactant into the tank body 114 is reached, and under the action of the stirring plate 1156, the viscosity of the waste liquid is reduced.

The stirring plate 1156 arranged in the outer periphery of the outer sleeve 1153 is in contact with the waste liquid. When the inner shaft 1151 rotates by the power provided by the driving motor 1159, the first coupling plate 1155 and the second coupling plate 1154 coupled to each other can make the outer sleeve 1153 rotate adaptively under the action of the hydraulic oil, so as to realize the mixing and stirring of the waste liquid by the stirring plates 1156. When the stirring plate 1156 is difficult to operate due to the too large viscosity of the waste liquid, the rotation speed sensor between the inner shaft 1151 and the outer sleeve 1153 can sense the signal in real time and send the sensed signal to the single-chip microcomputer. The single-chip microcomputer receives and analyzes the signal, and then controls the reagent filling assembly 116 to fill the surfactant into the tank 114, so as to reduce the viscosity of the waste liquid until the viscosity of the waste liquid in the tank 114 reaches a suitable viscosity. Here, the rotation speed sensor interrupts the magnetic field through the window of the vane rotor to detect the change of the rotation speed, which is a mature technology and will not be described here.
