Description

Technical Field

[0001] The utility model relates to the technical field of solid waste treatment, and more specifically, it relates to a harmful gas external detection system. Background Art

[0002] Solid waste treatment is a process of reducing its volume and accelerating its natural purification through physical means (such as crushing, compressing, drying, evaporation, incineration, etc.) or biochemical actions (such as oxidation, digestion and decomposition, absorption, etc.) and chemical actions such as pyrolysis gasification, so as to achieve reduction, harmlessness and resource utilization. It usually refers to solid, semi-solid and liquid substances discarded by humans in production and life. However, no matter what treatment method is adopted, there is still a certain amount of solid waste remaining in the end, and this part of the waste needs to be properly disposed of. Especially when treating waste, secondary pollution should be avoided, and it should be ensured that toxic and harmful waste does not cause harm to humans.

[0003] Before solid waste treatment, scientific compatibility is required. During the temporary storage process and disposal process of the compatible materials, harmful gases will be generated, which requires the detection of harmful gases. Therefore, a device capable of detecting harmful gases is needed. The main purposes of detecting harmful gases are as follows:

[0004] 1. Detect and analyze the components and concentrations of toxic and harmful gases in the air of the operation site, and take corresponding measures to control the excessive toxic and harmful substances.

[0005] 2. Use gas detector technology to detect and analyze the concentration of toxic and harmful gases in the flue gas discharged after purification

[0006] to evaluate the purification effect, find problems and make timely improvements, so that the concentration of toxic and harmful gases discharged into the atmosphere meets the national standards. Content of the Utility Model

[0007] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an external detection system capable of detecting harmful gases generated during the temporary storage process of solid waste.

[0008] To achieve the above purpose, the utility model provides the following technical solutions:

[0009] A harmful gas external detection system includes a waste temporary storage pit. The solid waste temporary storage pit is provided with an internal device and a gas detection device. The internal device consists of a special pipeline in the pit and a tracheal reel. The gas detection device pumps harmful gases to the outside through the special pipeline.

[0010] The gas detection device includes a gas detector, a filtration component, and a hose for connecting the gas detector and the filtration component. One end of the gas detection device is placed inside the trachea reel, and the other end sends the filtered harmful gas to the detection equipment. There are multiple gas detection devices, and the gas detector is electrically connected to a monitoring cabinet. The gas detector uses an FT-2104 gas detector.

[0011] One end of the gas detector is connected to an integrated intake pipe. The other port of the integrated intake pipe is connected to a three-way pipe. One port of the three-way pipe is connected to the filtration component, and the other port of the three-way pipe is connected to a drainage pump.

[0012] The present utility model is further configured as: the filtration component includes a front-end filter and a terminal filter, and the front-end filter and the terminal filter are connected through an air intake management protection sleeve.

[0013] The present utility model is further configured as: the other end of the integrated intake pipe is connected to a rotameter.

[0014] The present utility model is further configured as: the drainage pump is connected to a compressor to introduce compressed air into the three-way pipe.

[0015] The present utility model is further configured as: the cross-section of the waste temporary storage pit is trapezoidal.

[0016] Compared with the deficiencies of the prior art, the beneficial effects of the present utility model are:

[0017] By leveraging the existing wired network, the newly collected data can be integrated into the dispatching center. Through the dispatching center, the collected real-time data can be seamlessly integrated into the display big screen system, the existing APP software system, and the SMS alarm function system, enabling operators to monitor the collected data in real time. By controlling the gas concentration ratio of the two-way gas through a flow controller, it ensures that the detector can detect the gas concentration, while reducing the gas concentration ratio entering the gas sensor. At the same time, the alarm concentration setting value is adjusted accordingly on the detector, which plays a role in extending the service life of the gas detector.

[0024] As Figures 1 to 3 shown,

[0025] The harmful gas external inspection system includes the internal devices of the waste temporary storage pit 1 and the gas detection device. Two sets of wireless Wi-Fi base stations have been arranged in front of and behind the factory warehouse in the early stage. The coverage area of the Wi-Fi base station is 300 meters in diameter, and the wireless Wi-Fi network covers the entire material pit area. The two sets of wireless Wi-Fi base stations work simultaneously. When one is faulty, the other can achieve seamless switching. Ensure the stable and reliable Wi-Fi network in the factory area.

[0026] The cross-section of the waste temporary storage pit 1 is trapezoidal. The internal devices of the waste temporary storage pit 1 are composed of special pipes in the pit and the air pipe reel 2. The gas detection device pumps the harmful gas to the outside through the special pipe. One end of the gas detection device is placed in the air pipe reel 2. There are multiple gas detection devices, and each air pipe reel 2 has a set of gas detection devices.

[0027] The gas detection device includes a gas detector 3, a filter assembly, and a hose 4 for connecting the gas detector 3 and the filter assembly. One end of the gas detection device is placed in the air pipe reel 2, and the other end sends the filtered harmful gas to the detection equipment. There are multiple gas detection devices, and the gas detector 3 is electrically connected to the monitoring cabinet 5, and the signal is transmitted through the monitoring cabinet 5.

[0028] Each waste temporary storage pit 1 is equipped with 2 WiFi monitoring cabinets 5. Inside the monitoring cabinet 5, there is an analog quantity acquisition module with no less than 12 channels. The analog quantity acquisition module supports the RS485 MODBUS RTU serial communication protocol, and is equipped with a serial port to WIFI gateway to enable the data of the acquisition module to access the factory area WiFi network. A switching power supply is configured inside the monitoring cabinet 5 to supply power to the control cabinet and on-site terminal sensors. The WiFi monitoring cabinet 5 provides a standard industrial-level TCP / IP Modbus communication protocol and can be conveniently connected to the configuration control software.

[0029] By adopting the internal network of the factory area, the communication network is safe and reliable, the comprehensive wiring of the network is simple, and the total investment cost is relatively low; and the wireless WiFi communication network has redundancy, which is basically the same as the wired communication.

[0030] The gas detector 3 adopts the FT-2104 gas detector 3, and the FT-2104 can detect more than 200 kinds of toxic and harmful gases or oxygen. This kind of sensor has a long service life and can ensure continuous detection even in the most severe environment.

[0031] One end of the gas detector 3 is connected with an integrated intake pipe 6, and the other end of the integrated intake pipe 6 is connected with a rotameter 12 to control the gas concentration ratio and at the same time adjust the alarm concentration setting value on the detector accordingly, so as to play a role in prolonging the service life of the gas detector 3.

[0032] The other port of the integrated intake pipe 6 is connected with a tee 7. One port of the tee 7 is connected with a filtering component, and the filtering component includes a front filter 9 and an end filter 10. The front filter 9 and the end filter 10 are connected through an air intake management protection sleeve 11, and the air intake management protection sleeve 11 can avoid the damage to the pipe body caused by harmful gases during the air intake process.

[0033] The other port of the tee 7 is connected with a drainage pump 8, and the drainage pump 8 is connected with a compressor to introduce compressed air into the tee 7, ensuring that the gas detector 3 can detect the gas concentration and at the same time reducing the gas concentration ratio entering the gas detector 3.

[0034] Working principle: According to the level of materials in the waste temporary storage pit 1, manually tighten or loosen the take-air pipe protection sleeve disc, shorten or lengthen the take-air pipe protection sleeve, and correspondingly adjust the alarm concentration setting value on the gas detector 3. When the gas detector 3 collects harmful gases, the drainage pump 8 is used to control the gas concentration ratio to ensure that the detector can detect the gas concentration. The gas detector 3 collects harmful gases and conducts data analysis on them. The obtained data is aggregated into the data centralized acquisition module, and then the data is transmitted to the centralized switch through serial communication, and then the real-time data collected is seamlessly integrated into the display big screen system, the existing APP software system, and the SMS alarm function system through the dispatching center, enabling the operator to monitor the collected data in real time.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
