Description

Technical Field

[0001] This invention belongs to the field of coal gas condensate treatment technology, specifically relating to an intelligent coal gas condensate treatment system and method. Background Technology

[0002] In large integrated steel enterprises, coal gas, as an important energy medium, faces a series of problems in its comprehensive utilization. Due to the long distances between the production and consumption sites of various coal gases, transportation via gas pipelines is necessary. During transportation, the temperature of the coal gas decreases, causing saturated water to precipitate. If not drained promptly, this can increase pipeline resistance, form water seals, cause pipeline corrosion, and even pose safety hazards due to water hammer. Therefore, numerous drains are installed at the top of the gas pipelines for water drainage. However, different types of coal gas condensate contain various harmful substances and cannot be directly discharged; they must be collected and treated separately. Although each coal gas production site is equipped with corresponding coal gas wastewater treatment equipment, the long distances between these sites and collection pools, coupled with high investment costs due to pipeline transportation, and the susceptibility to corrosion and blockages, result in high maintenance costs.

[0003] The current method of using trucks to transport coal gas condensate has several drawbacks. The truck transport team needs to manually inspect the water level before notifying the driver, a process that consumes a significant amount of manpower. Furthermore, manual inspections are subject to numerous uncertainties, especially during night shifts when the collection tanks are located in coal gas areas, posing a considerable safety risk to inspectors and increasing the risk of environmental accidents caused by water overflow from the collection tanks. Additionally, accurately tracking the water volume and rate of water generation in each collection tank, as well as the amount of water transported and received at each receiving point, is extremely difficult. Specifically, the truck transportation process presents the following problems: 1. The water level inspection process is cumbersome: it still relies on on-site personnel to check the water level before contacting the driver, which adds unnecessary procedures, wastes human resources, and increases the risk to on-site inspection personnel.

[0004] 2. Lack of water volume prediction: It can only rely on on-site inspections by personnel, which increases the proportion of ineffective work for on-site personnel.

[0005] 3. No automatic location function: The collection pools do not have an automatic location function, and novice drivers need a long time to familiarize themselves with the routes and locations.

[0006] 4. Lack of vehicle route planning: Transportation is arranged entirely based on telephone notifications, without any reasonable planning of vehicle routes.

[0007] 5. Difficulty in data statistics: It is difficult to count the location and volume of water taken out and discharged by vehicles. The statistics of condensate generated by each gas, the amount received by the sewage treatment plant, the amount of water transported by water trucks and the distance traveled are either difficult to count or not accurate enough.

[0008] The five issues mentioned above have had a significant negative impact on business operating costs, staffing of inspection personnel, personal safety, and environmental protection. Currently, these problems can only be addressed manually, which not only greatly increases the workload of these staff but also makes it difficult to guarantee data accuracy. Summary of the Invention

[0009] To address the shortcomings of the existing technology, this invention discloses an intelligent gas condensate treatment system and method, employing the following technical means: A smart gas condensate treatment system includes an automatic water level detection device, a sensor assembly, an alarm device, a transport vehicle, and a data receiving and processing system. The gas pipeline extending from the mixing station is connected to the collection pool via a gas drainer. There are N gas drainers on one gas pipeline, and each gas drainer corresponds to a collection pool. The automatic water level detection device is installed on the collection pool; The sensor assembly includes a flow sensor, multiple temperature sensors, and a humidity sensor. The flow sensor is located on the gas pipeline, and the temperature and humidity sensors are located on the gas pipeline at the outlet of the mixing station and at each drain. The transport vehicle is equipped with a receiving and transmitting device and an on-board water pumping device. The automatic water level detection device, sensor components, alarm device, receiving and transmitting device, and vehicle-mounted pumping device are all connected to the data receiving and processing system.

[0010] The automatic water level detection device can be a liquid level sensor. Alternatively, this invention provides a preferred automatic water level detection device, which includes a pull bottle, a pull cable, an SM card transmitter, a base, a balance bar connecting pin, a balance bar, a micro-switch, a counterweight, and a support rod. The support rod is mounted on the base, and the micro-switch and SM card transmitter are mounted on the support rod. The micro-switch and SM card transmitter are connected by signal, and the SM card transmitter is connected by signal to the data receiving and processing system. The balance rod is rotatably connected to the top of the support rod through the balance rod connecting pin. The pull bottle is mounted on one end of the balance rod through the pull line, and the counterweight is mounted on the other end of the balance rod. The bottle floats on the surface of the collection pool.

[0011] Furthermore, the vehicle-mounted water pumping device includes a water tank, a water pump, and a suction pipe. A flow meter is installed on the suction pipe, and the flow meter is connected to the data receiving and processing system. The receiving and transmitting device is located in the driver's cab of the transport vehicle.

[0012] This invention also discloses an intelligent treatment method for coal gas condensate, which uses any of the intelligent treatment systems described above and includes the following steps: The automatic water level detection device is used to detect the water level of condensate in the collection tank. If the water level reaches a preset height, the automatic water level detection device sends a "condensate water level signal of the j-th collection tank" to the data receiving and processing system, where j=1.2…N. After receiving the "condensate water level signal of the j-th collection pool", the data receiving and processing system sends a "transportation instruction" to the receiving and transmitting device of the transport vehicle. After receiving the instruction, the transport vehicle travels to the j-th collection pool to extract the condensate water and transfers the extracted condensate water to the sewage treatment plant. The sensor assembly transmits the monitored gas temperature and relative humidity information to the data receiving and processing system in real time. Based on the real-time temperature and relative humidity monitoring results of the gas, the data receiving and processing system determines whether the water level in the j-th collection pool has reached the preset height. If it is predicted that the water level should reach the preset height but the system does not receive the "the condensate water level in the j-th collection pool is in place signal" sent by the automatic water level detection device, the data receiving and processing system controls the alarm device to sound an alarm. The alarm device can be an audible and visual alarm.

[0013] Furthermore, the specific method by which the data receiving and processing system determines whether the water level in the j-th collection tank has reached the preset height based on the real-time temperature and relative humidity monitoring results of the gas is as follows: S1. Calculate the amount of condensate released in the j-th collection tank per cubic meter of dry coal gas;

[0014] In the formula, W j The amount of condensate collected in the j-th collection tank, in g / m³ 3 Dry gas; d j-1 Let be the absolute water vapor content (g / m³) in the gas when the gas flows through the gas pipeline at the (j-1)th drainer. 3 For dry coal gas, when j is 1, d1 is the absolute content of water vapor in the coal gas when the coal gas flows out of the mixing station; d j Let be the absolute water vapor content (g / m³) in the gas pipeline when the gas flows through the j-th drainer. 3 Dry gas; P vj-1 , P vj Let be the partial pressure of water vapor (Pa) when the gas flows through the gas pipeline at the (j-1)th and jth drainers, respectively. When j is 1...P vj-1 This refers to the partial pressure of water vapor when the gas flows out of the mixing station; M v The molar mass of water vapor is 18 g / mol; R Universal gas constant, 8.314 J / (mol·K); T : The absolute temperature of the gas in the gas pipeline at the j-th drain, in K; S2, based on the above calculations W j The total amount of condensate collected in the j-th collection tank is calculated based on the value, gas flow rate, and time information. W j × Gas flow rate = The amount of condensate collected per hour in the j-th collection tank, where the gas flow rate is in meters per second (m³). 3 / h dry gas; If the temperature at each point in the gas pipeline remains stable during gas transportation, then the amount of condensate collected per hour in the j-th collection pool multiplied by the collection time (h) is the amount of condensate collected in the j-th collection pool. If the temperature at various points in the gas pipeline is unstable during gas transportation, the amount of condensate collected per hour in the j-th collection pool during each temperature stabilization phase is calculated, multiplied by the collection time (h) of that temperature stabilization phase, to obtain the amount of condensate collected in each temperature stabilization phase. The sum of the condensate collected in all temperature stabilization phases is the amount of condensate collected in the j-th collection pool.

[0015] Furthermore, when the gas temperature is higher than the dew point, the partial pressure of water vapor is the actual partial pressure of water vapor, which is obtained by multiplying the relative humidity by the saturated partial pressure of water vapor at that temperature; when the gas temperature is lower than the dew point, the partial pressure of water vapor is the saturated partial pressure of water vapor; the saturated partial pressure of water vapor can be obtained by consulting the saturated vapor pressure table based on the temperature value.

[0016] Furthermore, the data receiving and processing system uses the receiving and transmitting devices of the transport vehicles to obtain the location information of the transport vehicles in real time. When the transport vehicles are working, the receiving and transmitting devices simultaneously send a "working signal" to the data receiving and processing system. When the transport vehicles are idle, the receiving and transmitting devices simultaneously send a "waiting signal" to the data receiving and processing system. When the data receiving and processing system receives a "condensate water level signal for the j-th collection pool", it will select the idle transport vehicle closest to the j-th collection pool to go to the j-th collection pool, and at the same time send the precise location information of the j-th collection pool to the idle transport vehicle.

[0017] Furthermore, the automatic water level detection device is used to detect the water level of the condensate in the collection tank. If the water level reaches a preset height, the automatic water level detection device sends a "condensate level in the j-th collection tank reaches the target level signal" to the data receiving and processing system. Specifically: As the water level in the collection tank rises, the bottle rises. The side of the balance bar with the counterweight moves downward under the influence of the counterweight's weight. When the water level in the collection tank reaches the preset height, the balance bar moves down to contact the micro switch, triggering the micro switch to open. The SM card transmitter then sends a "the j-th collection tank condensate level is reached signal" to the data receiving and processing system.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. Significantly Enhanced Safety: This invention greatly improves operational safety. In practical applications, on-site personnel no longer need to enter the gas area for inspection. This effectively avoids the safety risks that personnel may face due to entering dangerous areas and reduces safety hazards in gas area operations.

[0019] Significant environmental benefits: The intelligent gas condensate treatment system enables timely and accurate monitoring of wastewater discharge, preventing spillage accidents that could occur due to untimely manual inspections. This intelligent monitoring method not only protects the environment and reduces pollution from wastewater overflows, but also meets the stringent environmental protection requirements of modern industry.

[0020] 2. Optimized and Efficient Personnel Allocation: Taking the 180 external water collection pools of Shandong Iron & Steel Group's Laiwu Branch as an example, under the traditional model, two people were needed per shift to inspect every 3-5 collection pools, with each inspection taking about 30-40 minutes, requiring a total of 36-60 people and a total shift work time of 2160 to 2400 minutes. However, with this invention, all these inspection personnel can be eliminated, greatly saving labor costs and improving the company's operational efficiency.

[0021] 3. Leading with Innovative Technical Architecture: This solution adopts a three-layer architecture of IoT sensing, intelligent decision-making, and precise execution, achieving a complete digital reconstruction of the gas condensate management process. This innovative technical architecture not only improves the level of intelligent management but also provides a reusable technical paradigm for the intelligent transformation of traditional heavy industries. It has strong promotional value and demonstration significance, and can help more traditional heavy industrial enterprises achieve digital and intelligent upgrades. Attached Figure Description

Detailed Implementation

[0024] The technical solutions in the embodiments of the present invention will now be clearly and completely described in conjunction with the accompanying drawings.

[0025] Example 1 This embodiment discloses an intelligent gas condensate treatment system, including an automatic water level detection device, a sensor assembly, an alarm device, a transport vehicle, and a data receiving and processing system; like Figure 1 As shown, the automatic water level detection device includes a pull bottle 1, a pull cable 2, a balance bar bracket 3, an SM card transmitter 4, a base 5, a balance bar connecting pin 6, a balance bar 7, a micro-switch 8, a counterweight 9, and a support rod 10. The support rod 10 is mounted on the base 5. The micro-switch 8 and the SM card transmitter 4 are mounted on the support rod 10 and are signal-connected. The SM card transmitter 4 is signal-connected to the data receiving and processing system. The balance bar 7 is rotatably connected to the top of the support rod 10 via the balance bar connecting pin 6. A balance bar bracket 3 is also provided on the support rod 10 below the balance bar 7. The pull bottle 1 is mounted at one end of the balance bar 7 via the pull cable 2, and the counterweight 9 is mounted at the other end of the balance bar 7.

[0026] like Figure 3 As shown, the gas transportation system includes a mixing station 11, a gas pipeline 12, a drainer 13, a collection tank 14, and a gas user terminal 15. After the gas is output from the mixing station 11, it is transported to the gas user terminal 15 via the gas pipeline 12. During the gas transportation process via the gas pipeline 12, condensate generated due to temperature changes is collected in the collection tank 14 via the drainer 13. A gas pipeline 12 typically has multiple drainers 13 and collection tanks 14, with each drainer 13 and collection tank 14 corresponding to another. This section describes the conventional structure of existing gas transportation systems and is intended to illustrate the installation location and working principle of the intelligent gas condensate treatment system of this invention; therefore, the technical details of the gas transportation system will not be elaborated further.

[0027] Each collection pool 14 is equipped with a set of automatic water level detection devices. The pull bottle 1 of the automatic water level detection device is located on the water surface of the collection pool 14. When the water level in the collection pool 14 rises, the pull bottle 1 rises. The side of the balance bar 7 with the counterweight 9 moves downward under the influence of the weight of the counterweight 9. When the water level of the condensate reaches the preset height (the preset height is set by technicians based on experience, which can be the maximum amount of water that the collection pool can collect without splashing), the balance bar 7 moves down to contact the micro-switch 8, triggering the micro-switch 8 to open. At this time, the SM card transmitter 4 sends a "condensate water level signal of the j-th collection pool" (j=1.2…N, where N is the total number of collection pools) to the data receiving and processing system. After receiving the signal, the data receiving and processing system sends a "transportation instruction" to the transport vehicle. After receiving the instruction, the transport vehicle travels to the j-th collection pool to extract the condensate and transfers the extracted condensate to the sewage treatment plant.

[0028] The transport vehicle 17 is equipped with a receiving and transmitting device 18 and an on-board water pumping device. The on-board water pumping device includes a water tank 19, a water pump, and a suction pipe 20. A flow meter 21 is installed on the suction pipe 20. The transport vehicle uses the on-board water pumping device to transfer the condensate from the collection tank 14 to the sewage treatment plant. The flow meter 21 is used to detect the amount of water pumped. The receiving and transmitting device 18 is used to send "location information" to the data receiving and processing system and to receive "transportation instructions" sent by the data receiving and processing system.

[0029] The sensor assembly 16 includes a flow sensor, multiple temperature sensors, and a humidity sensor. The flow sensor is installed on the gas pipeline 12 to detect the gas flow rate. The temperature and humidity sensors are installed on the gas pipeline 12 at the outlet of the mixing station 11 and at each drain 13 to monitor the temperature and relative humidity of the gas in that section in real time. The sensor assembly 16 is connected to the data receiving and processing system and sends the monitoring results to the data receiving and processing system in real time. Based on the real-time temperature and relative humidity monitoring results of the gas, the data receiving and processing system determines whether the water level in the j-th collection pool 14 has reached the preset height. If it is predicted that the water level should reach the preset height but the "the j-th collection pool condensate water level is in place signal" sent by the SM card transmitter 4 is not received, the data receiving and processing system controls the alarm device to sound an alarm, reminding the staff to check in time to avoid the occurrence of faults.

[0030] Specifically, the data receiving and processing system determines whether the water level in the j-th collection tank 14 has reached the preset height based on the real-time temperature, relative humidity, and flow rate monitoring results of the gas as follows: S1. Calculate the amount of condensate released from the j-th collection tank per cubic meter of dry coal gas, where j takes values ​​from 1, 2…N, and N is the total number of collection tanks: The condensate in the first collection tank is released from the gas flowing through the gas pipeline between the mixing station and the first drainer. When j≥2, the condensate in the j-th collection tank is released from the gas flowing through the gas pipeline between the (j-1)-th and j-th drainers. Based on this, The formula for calculating the amount of condensate precipitated in the j-th collection tank per cubic meter of dry coal gas is:

[0031] In the formula, W j The amount of condensate collected in the j-th collection tank, in g / m³. 3 Dry gas; d j-1 d1 represents the absolute water vapor content in the gas when the gas flows through the gas pipeline at the (j-1)th drainer (when j is 1, d1 is the absolute water vapor content in the gas when the gas flows out of the mixing station), unit: g / m³ 3 Dry gas; d j Let be the absolute water vapor content in the gas as it flows through the gas pipeline at the j-th drain, expressed in g / m³. 3 Dry gas; P vj-1 , P vj These are the partial pressures of water vapor when the gas flows through the gas pipeline at the (j-1)th and jth drainers, respectively (when j is 1). P v0 This refers to the partial pressure of water vapor when the gas flows out of the mixing station, in Pa. When the gas temperature here is higher than the dew point, the partial pressure of water vapor is the actual partial pressure of water vapor, which is obtained by multiplying the relative humidity by the saturated partial pressure of water vapor at that temperature. When the gas temperature here is lower than the dew point, the partial pressure of water vapor is the saturated partial pressure of water vapor (at which point the relative humidity is 100%). The saturated partial pressure of water vapor can be obtained by consulting the saturated vapor pressure table based on the temperature value. M v The molar mass of water vapor is 18 g / mol; R Universal gas constant, 8.314 J / (mol·K); T : The absolute temperature of the gas in the gas pipeline at the j-th drain, in K; S2, based on the above calculations W j Value, and gas flow rate (m³) 3 The total amount of condensate collected in the j-th collection tank is calculated using the dry gas ( / h) and time information. W j × Gas flow rate = condensate volume collected per hour in the j-th collection tank; If the temperature at each point in the gas pipeline remains stable during gas transportation, then the amount of condensate collected per hour in the j-th collection pool multiplied by the collection time is the amount of condensate collected in the j-th collection pool. If the temperature at various points in the gas pipeline is unstable during gas transportation, the amount of condensate collected per hour in the j-th collection pool during each temperature stabilization phase is calculated, multiplied by the collection time of that temperature stabilization phase, to obtain the amount of condensate collected in each temperature stabilization phase. The sum of the condensate collected in all temperature stabilization phases is the amount of condensate collected in the j-th collection pool.

[0032] The system predicts whether the amount of condensate collected in the j-th collection tank has reached the preset water level in the j-th collection tank (based on the amount of condensate calculated in step S2, the volume of the j-th collection tank, and the preset water level). If the preset water level is predicted to be reached but no "condensate water level signal for the j-th collection tank" is received, the data receiving and processing system controls the alarm device to sound an alarm, reminding staff to check in time to avoid malfunctions.

[0033] The data receiving and processing system can acquire the real-time location information of the transport vehicles based on their receiving and transmitting devices. When the transport vehicles are working, the receiving and transmitting devices simultaneously send a "working signal" to the data receiving and processing system. When the transport vehicles are idle, the receiving and transmitting devices simultaneously send a "waiting signal" to the data receiving and processing system. When the data receiving and processing system receives a "condensate water level signal for the j-th collection pool", it will select the idle transport vehicle closest to the j-th collection pool and send it to the j-th collection pool. At the same time, it will send the j-th collection pool's precise location information to the idle transport vehicle, so that the idle transport vehicle can quickly find the location of the j-th collection pool.

[0034] The transport vehicle 17 is also equipped with a water volume detection device, which is connected to the flow meter 21 and the data receiving and processing system. This device calculates the water volume in the collection pool 14 based on the monitoring data from the flow meter 21 and transmits the data to the data receiving and processing system. The system compares the calculated condensate volume with the actual collected condensate volume to determine if they match, providing data support for subsequent automatic intelligent detection equipment malfunctions. Simultaneously, the water volume in each collection pool is statistically analyzed. Based on the originally labeled type of gas condensate in the collection pool and the factory to which it belongs, the system can query the water volume generated by each collection pool within a specific time period, or the wastewater volume generated by each factory within a corresponding time period. By locating the unloading point and querying the wastewater volume received by each factory, and simultaneously statistically analyzing the transport volume of each water truck per shift, the entire transportation process can be managed digitally. For example, based on the above statistical data, it is easier to calculate transportation costs, driver workload, driver compensation, etc.
