Description

Technical Field

[0001] The present invention relates to the technical field of resource utilization of construction waste, and particularly to a model device for detecting the physical and chemical properties of construction waste. Background Art

[0002] To dispose of a large amount of waste construction waste generated in urban infrastructure construction, a series of technologies and equipment for resource utilization of construction waste have rapidly developed. The process of resource utilization of waste construction waste involves key processes such as phase separation and regulation of the physical and chemical properties of slurry. The vibration parameters for phase separation and the process parameters for physical and chemical regulation in the resource utilization process of construction waste with different properties are very different. Intelligently perceiving the changes in the physical and chemical properties throughout the process of resource utilization of waste construction waste and making real-time adjustments to the production process parameters are the keys to achieving efficient, green, and low-carbon resource utilization. Currently, there is a method for improving the resource utilization of shield construction waste (CN113182328A), which conducts moisture content tests on shield construction waste and adopts different treatment processes and resource utilization paths for shield construction waste with different moisture contents. However, this process method only conducts a single-parameter (moisture content) test when the construction waste enters the site, lacking the perception of the physical and chemical property parameters during the subsequent slurry regulation process in resource utilization. The reason is that there is a lack of an integrated and intelligent device for perceiving the physical and chemical properties of construction waste in the field of resource treatment of construction waste. Another patent, CN116637902A, a method and system for intelligent multi-functional resource treatment of waste construction waste, mentions that the pH value sensor and near-infrared spectrometer in its data acquisition module can perceive the chemical parameters of the slurry and the water tank. The sensors mentioned in this system have low integration and are difficult to install, manifested in that its data transmission line and power supply line will inevitably affect resource production. At the same time, no solution to the waterproof problem of optical sensors is proposed.

[0003] Problems and Defects of the Existing Technology:

[0004] (1) There are few target parameters for perceiving the physical and chemical properties of multi-source construction waste, and it is impossible to comprehensively grasp the changes in the physical and chemical properties throughout the process of construction waste resources. (CN113182328A)

[0005] (2) The degree of intelligence in perceiving the physical and chemical properties of construction waste is low (CN113182328A), and the integration degree of the device is low (CN116637902A)

[0006] (3) The sensor lines for perceiving the physical and chemical properties of materials during the resource utilization process of construction waste affect the normal production process. At the same time, due to the harsh working environment of the sensors (high moisture content, multi-source slurry), the damage rate of the sensors is relatively high, resulting in low accuracy or inability to measure the measured physical and chemical parameters.

[0059] The external computer can also wirelessly control the operation of the model device for detecting the physical and chemical properties of muck. On the one hand, it can sense the physical and chemical properties of muck at different stages, and on the other hand, it can instantaneously turn on or off the intelligent sensor for the physical and chemical properties of shield muck as needed to extend the working time of the device.

[0060] Example 1: Muck slurry incoming pool

[0061] The muck slurry incoming pool serves as the raw material area of the muck resource utilization system, and its main function is to temporarily receive the muck and slurry newly generated in urban infrastructure construction. In the existing muck resource utilization process, by initially detecting the water content of the muck slurry, with 30% water content as the dividing line, the muck is resource-utilized into different products; however, it is obviously too rough to carry out resource utilization of muck only relying on this parameter of water content, ignoring the influence of the mineral composition, foaming agent, etc. of the muck slurry on the subsequent resource utilization process parameters.

[0062] For example, for waste muck with a high content of clay minerals and a foaming agent, it is necessary to increase the flushing water pressure in the muck phase separation module. When necessary, a dispersant needs to be added to reduce the adhesion of the muck. At the same time, an antifoaming agent needs to be added to eliminate the foam in the slurry liquid after flushing, avoiding blockage of the muck in the phase separation module and preventing malfunctions in the resource utilization equipment. Therefore, in order to reduce the operating failures of the resource utilization equipment, when used on-site, the staff will use the maximum flushing water pressure without discrimination and add a certain amount of dispersant and antifoaming agent. However, many waste mucks with a low content of clay minerals do not require too high a flushing water pressure and do not need external additives, which results in the problems of high energy consumption and insufficient economic benefits in the existing muck resource process.

[0063] If the main mineral components and the content of the foaming agent in each batch of waste muck can be quickly detected in the raw material pool, the subsequent muck phase separation module can adjust the resource utilization process parameters according to these physical and chemical information, effectively improving the resource utilization efficiency and benefits. In the model equipment for detecting the physical and chemical properties of muck used in the slurry pool, a Fourier transform infrared spectrometer is optionally installed in the optical sensing module 2 to quickly detect the main mineral components and the content of the foaming agent in the muck slurry; a moisture content sensor and a pH sensor are optionally installed in the electrochemical sensing module 6 to detect the moisture content and pH value of the muck, providing a decision-making basis for the subsequent resource utilization treatment path and means. According to the physical and chemical parameters of the muck slurry quickly detected by the Fourier transform infrared spectrometer, the optimal resource utilization plan for different batches can be initially determined, effectively reducing the addition amount of external additives such as antifoaming agents and dispersants; at the same time, the flushing water pressure during sediment separation can be intelligently adjusted according to the mineral components, greatly saving energy and improving the economic benefits of muck slurry resource utilization.

[0064] Example 2: Mud Flocculation - Curing Pond

[0065] After the muck slurry undergoes sediment separation, clean high-value sand and gravel aggregates and high-moisture-content slurry are obtained. The high-moisture-content slurry needs to be further flocculated, settled, dehydrated, and cured into a concentrated slurry with the ability to develop structural strength in the mud flocculation - curing pond; this process requires the addition of flocculants and curing agents. In engineering, there is no specific basis and dosing standard for the addition of flocculants and curing agents. Dosing according to experience often results in excessive or insufficient dosing, causing waste of flocculants and curing agents or the quality of the muck resource products not meeting the standards.

[0066] In the model equipment for detecting the physical and chemical properties of muck used in the mud flocculation - curing pond, a Fourier transform infrared spectrometer is optionally installed in the optical sensing module 2 to quickly detect the main mineral components of the muck slurry; a moisture content sensor and a pH sensor are optionally installed in the electrochemical sensing module 6, and the central signal processing and communication module 4 integrates and transmits the physical and chemical information of the slurry to the control decision-making terminal to intelligently control the dosing amount of flocculants and curing agents.

[0067] Example 3: Intermediate water tank

[0068] The intermediate water tank is a container for recycling the supernatant of the flocculation-solidification tank and removing water from the concentrated mud by pressure filtration. Dispersants, defoamers added during the separation of water-rich mud and sand in the tank, as well as flocculants and solidifying agents added during flocculation-solidification, and various pollutants (organic matter, shield grease, alkaline substances) leached from the soil also exist; the presence of these substances affects the addition amount of additives such as dispersants and defoamers during the process of reusing intermediate water on the one hand, and is also related to the harmless treatment and discharge of excess intermediate water on the other hand.

[0069] Model devices for detecting the physical and chemical properties of muck are placed in the intermediate water tank. The pH sensor, OPR sensor, chloride ion sensor, and ammonia nitrogen sensor in the electrochemical sensing module 6, as well as the turbidity sensor, nitrate sensor, and oil-in-water sensor in the optical sensing module 2, monitor the water quality in real time. After being integrated with the central signal processing and communication transmission module, the data is displayed at the control decision terminal to guide the harmless treatment and discharge of intermediate water. At the same time, the pH sensor and the Fourier transform infrared spectrometer in the optical sensing module provide guidance for the reuse of intermediate water. The pH value affects the addition amount of flocculants and solidifying agents during the flocculation-solidification process. The Fourier transform infrared spectrometer can detect the content of various additives (dispersants, defoamers, flocculants, solidifying agents, etc.) in water, and combined with the mud quality during the mud and sand separation process, the content of additives that still need to be added can be calculated, effectively saving the addition of various additives and improving the economic benefits of muck slurry resource utilization.

[0070] The beneficial effects of the present invention are: (1) improving the intelligence and integration degree of sensors for the physical and chemical properties of materials during the process of muck resource utilization; (2) realizing a more comprehensive perception of the physical and chemical properties of muck resource utilization, thereby guiding the efficient resource utilization of muck slurry and enhancing the economic benefits during the process of muck resource utilization; (3) overcoming the problem of high failure rate of existing sensors through sealed design and modular combination; (4) wireless communication transmission and magnetic adsorption design, improving the engineering adaptability of the sensor device, greatly reducing the installation and maintenance workload of the sensor device, and taking into account the portability and flexibility of the sensing device.

[0071] The above content is a further detailed description of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present invention.
