Description

Technical Field

[0001] This utility model belongs to the technical field of gas generator sets, and specifically relates to a containerized multi-unit parallel gas generator set. Background Technology

[0002] Existing containerized gas generator sets mostly adopt a single high-power unit or a limited number of small and medium-power units integrated together. Although the single-unit solution has a simple structure, it suffers from problems such as large equipment size, limited transportation and installation, and insufficient load regulation capability; while the parallel solution of a few units (such as 2 to 3 units) has a certain degree of redundancy, it is difficult to achieve higher total output power and maintenance space utilization within the limited container space, and the total power is usually difficult to exceed 1MW.

[0003] With the increasing demand from scenarios such as distributed energy stations, industrial and commercial load peak shaving, new energy grid connection support, and emergency backup, the market demand for high power density gas-fired power generation equipment in single containers is becoming increasingly urgent. For example, when it is necessary to achieve an output of more than 1.5MW in a 40-foot standard container, the traditional layout of 3 units can no longer meet the dual requirements of power demand and cooling heat dissipation, and the complexity of airflow organization and cooling circuits also increases accordingly.

[0004] Furthermore, existing units mostly rely solely on conventional cooling circuits, lacking online monitoring and sampling methods for the circulation of coolant in long pipelines. This makes it difficult to detect coolant deterioration or leaks in a timely manner, affecting the stability and safety of the units. At the control level, traditional multi-unit parallel systems often cannot achieve intelligent, graded start-up and shutdown and balanced control when the load fluctuates significantly. This results in operating efficiency deviating from the optimal range, increasing fuel consumption and affecting the overall lifespan and reliability of the unit.

[0005] Therefore, existing technologies have significant shortcomings in terms of single-container power expansion, cooling circuit monitoring, airflow heat dissipation organization, and distributed intelligent control. There is an urgent need for a new type of containerized gas generator set that can integrate six 300kW natural gas generator sets in a standard container, achieve a stable output of 1.8MW per container, and take into account space utilization, maintenance convenience, safety and reliability, and operating efficiency.

[0006] • The power output of a single unit is difficult to exceed 1MW, which is insufficient to meet the needs of distributed energy stations and high-load industrial and commercial applications;

[0007] • When multiple units are arranged in a limited container space, they are often constrained by heat dissipation and maintenance passages, which can easily lead to overheating, crowded layout and inconvenient maintenance.

[0008] • Cooling systems mostly rely on conventional long pipeline circulation, lacking online monitoring and sampling of coolant conditions, resulting in problems where leaks or deterioration are difficult to detect in a timely manner;

[0009] • When the load fluctuates, multi-unit parallel systems lack intelligent graded start-up and shutdown and balancing control strategies, which leads to operating efficiency deviating from the optimal range, increased gas consumption, and shortened equipment life. Utility Model Content

[0010] In view of this, this utility model provides a containerized multi-unit parallel gas generator set, integrating six 300 kW units within the container to achieve a stable output of 1800 kW, significantly improving the power density per unit volume. The cooling system adopts a dual-loop design, and sampling / detection devices are installed at key locations in the pipelines, enabling coolant status monitoring without shutting down the system, thereby significantly improving operational safety and reliability. Regarding airflow organization, a highly efficient cooling airflow is formed using the front-end air intake grille, radiator, and fan, combined with a double-sided ventilation structure, effectively preventing heat accumulation and ensuring continuous and efficient unit operation. Therefore, it surpasses existing technologies in power output, space utilization, cooling, intelligent control, and operational safety, possessing significant engineering application value and promotional significance.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1

[0039] like Figures 1 to 10 As shown, a containerized multi-unit parallel gas generator set includes a container 1 and gas generator sets. The container 1 includes a working area 11 and a heat dissipation area 12. Six gas generator sets are installed in the working area 11 and connected in parallel. Each of the six gas generator sets is equipped with an independently controlled electrical cabinet. The front end of the heat dissipation area 12 is provided with an air inlet grille 10. The heat dissipation area 12 is equipped with a cooling component for cooling the gas generator sets in the working area 11. The container 1 is equipped with an air intake and exhaust component and a control component. The air intake and exhaust component filters the gas entering the gas generator sets. The control component includes a control panel and a distributed monitoring module, which are electrically connected to the six gas generator sets for controlling the gas generator sets. The gas generator sets are 300KW generators.

[0040] The cooling assembly includes a radiator 21 installed in the heat dissipation area 12 of container 1. A fan 25 is connected to the air inlet grille 10 and corresponds to the radiator 21 for heat exchange. The return and drain ports of the radiator 21 are sealed with main pipes 22, and a circulation pump 24 is installed on the main pipe 22 at the drain port to provide power for transporting the coolant. Six sets of branch pipes 23 are provided between the two main pipes 22, and a gas generator set is connected through the six sets of branch pipes 23 for heat dissipation. Sampling / detection devices 4 are installed on the six sets of branch pipes 23 and the main pipe 22 to detect the temperature, level, and impurities of the flowing coolant. The sampling / detection device 4 includes a temperature sensor, a level sensor, and an impurity content sensor, and is electrically connected to the control panel. The air intake and exhaust assembly includes a filter grille 31, and the filter grille 31 is equipped with… The air intake compartment 32 is equipped with a filter 33 for filtering the passing gas. The exhaust port of the filter 33 is sealed with an air intake pipe 34, and the air intake pipe 34 is provided with six sets of air intake branch pipes 3523, which are respectively connected to the air intake chambers of six gas generator sets. The exhaust chambers of the gas generator sets are connected to exhaust pipes 36 for discharging exhaust gas. The control component is installed at the front end of the container 1. The control component also includes a multimedia intelligent touch screen for displaying the unit's operating status, warning information, historical records, and operation prompts. The multimedia intelligent touch screen supports touch operation for selecting functions and inputting parameters. The distributed monitoring module has multiple sensors for cooling, air intake, exhaust, and gas supply, and is electrically connected to the control panel. An end door 8 is hinged at the heat dissipation area 12 of the container 1. The end door 8 is used for entering and exiting the container 1 by opening and closing. The end door 8 is provided with a second louver 9.

[0041] In actual operation: The operator initiates the start command through the multimedia intelligent touch screen of the front control component of container 1. The distributed monitoring module first performs a pre-test on the cooling, air intake, exhaust, and gas supply systems, and feeds back the normal parameters of each link to the control panel. The air intake and exhaust components then start. Outside air enters the air intake chamber 32 through the air filter grille 31, and after impurities are filtered out by the filter 33, it is precisely delivered to the air intake chambers of the six 300KW gas generator sets through the air intake pipe 34 and the branch air intake branch pipes 3523. At the same time, the gas supply system supplies gas on demand, which mixes with the filtered air and completes combustion to drive power generation in the unit. The six units operate in parallel. The heat generated during power generation is carried away by the cooling components. The circulating pump 24 provides power to the dual-loop cooling system. The coolant is distributed through the main pipe 22 to each branch pipe 23 and enters the corresponding unit. After absorbing heat, it flows back to the radiator 21. The fan 25, in conjunction with the air intake grille 10, introduces cold air to exchange heat with the radiator 21 to achieve cooling. The sampling / detection devices 4 on branch pipe 23 and main pipe 22 collect real-time data on coolant temperature, level, and impurities. The distributed monitoring module synchronously collects unit operating parameters and exhaust status information, all of which are displayed on the touchscreen. When an abnormality is detected, the control system immediately triggers a safety interlock, cutting off the gas supply and issuing an alarm. The system can achieve phased start-up and shutdown and balancing control of the units via the control panel according to load changes, ensuring efficient and stable operation. Exhaust gas is collected and discharged through the exhaust pipes 36 of each unit, and the louvers on the end doors 8 assist in ensuring ventilation within the enclosure. Example 2

The outer shell is formed by bending and welding Q235 high-strength steel plate, with a thickness of not less than 2.0mm. The surface is treated with pickling, rust removal, and phosphating, followed by electrostatic powder coating to form a protective layer with good weather resistance and corrosion resistance. The color is industrial gray-white, meeting the requirements for long-term use in maritime transport and outdoor environments. Container 1 is equipped with standard corner fittings and shock-absorbing support devices at the bottom, facilitating transportation and hoisting while maintaining vibration resistance during operation.

A first bushing 73 is provided at one end of the side wall 6, and the first pin 72 is rotatably installed in the first bushing 73. A second pin 75 is provided between the container 1 and the side wall 6, and a second bushing 76 is rotatably installed on the two second pins 75. The two second bushings 76 are connected by a support assembly, which is a support rod 741, and both ends are fixedly snapped onto the second bushings 76 respectively.

[0044] In actual operation: the side wall 6 is rotated along the first pin 72, and the side wall 6 can be opened or closed by the engagement of the support rod 741 with the second bushing 76, facilitating maintenance or heat dissipation. Example 4

[0045] Based on Example 3, such as Figure 12 As shown, the support assembly includes a first screw 742 and a second screw 743 fixedly mounted on the second bushing 76, and the first screw 742 and the second screw 743 are connected by a double-threaded tube 744. Operating the double-threaded tube 744 drives the first screw 742 and the second screw 743 to move synchronously in opposite directions or towards each other. The thread directions of the first screw 742 and the second screw 743 are opposite.

[0046] In actual operation: the double-threaded tube 744 drives the first screw 742 and the second screw 743 to move synchronously in opposite directions or towards each other, thereby adjusting the distance between the first screw 742 and the second screw 743, and thus adjusting the opening angle of the side wall 6 for easy adjustment.
