Description

Technical Field

[0001] This utility model mainly relates to the technical field of methanol engine unit pipelines, specifically a preheating pipeline for the unit. Background Technology

[0002] A methanol engine unit is a power unit consisting of an engine that uses methanol as fuel and its related supporting equipment. It mainly includes a methanol engine, a fuel supply system, an ignition system, a cooling system, and a lubrication system. The working principle of a methanol engine unit is based on the combustion of methanol. First, the fuel supply system injects methanol into the combustion chamber of the engine, where it mixes with air to form a combustible mixture. For spark-ignition methanol engines, the ignition system generates an electric spark at an appropriate time to ignite the mixture, causing it to burn rapidly and produce high-temperature, high-pressure gas. This gas pushes the piston downward, which in turn drives the crankshaft to rotate via the connecting rod, converting thermal energy into mechanical energy. During this process, the cooling system and the lubrication system work together to ensure the normal operation of all engine components.

[0003] The preheating piping system is divided into cold water piping and hot water piping. In the current existing engine units, each preheating piping only provides preheating services for one unit. This means that more pipes, valves, pumps and other equipment are needed to preheat the corresponding units. This not only increases the initial construction cost, but also occupies more space. In places with limited space, it may lead to layout difficulties. Moreover, the preheating pumps and other equipment in each preheating piping system consume energy. With a large number of units, the number of independent pipes also needs to increase, making the piping more complex. In the long run, the cost is high and the later maintenance is more difficult. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that current preheating pipelines only provide preheating services for one unit. This necessitates the installation of more pipes, valves, pumps, and other equipment for each unit in each plant, increasing initial construction costs, complicating the pipeline system, and resulting in high maintenance costs.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

The preheating pipeline includes a hot water pipeline and a cold water pipeline.

[0007] The hot water pipeline includes a first conduit and a hot water pipe, which are connected by an elbow. The hot water pipe is connected to a first hot water connecting pipe and a second hot water connecting pipe by a tee joint and an elbow, respectively. The first hot water connecting pipe and the second hot water connecting pipe are respectively connected to the hot water ports on the two engine units.

[0008] The cold water pipeline includes a second conduit and a cold water pipe, which are connected by an elbow. The cold water pipe is connected to a first cold water connecting pipe and a second cold water connecting pipe via a tee and an elbow, respectively. The first cold water connecting pipe and the second cold water connecting pipe are respectively connected to the cold water inlets on the two engine units.

[0009] Furthermore, the upper ends of the first hot water connecting pipe and the second hot water connecting pipe are respectively provided with a first ball valve and a second ball valve.

[0013] Furthermore, a first liquid injection / drainage port is provided at one end of the hot water pipe.

[0014] Furthermore, a second liquid injection and drainage port is provided at one end of the cold water pipe.

[0025] Please refer to the appendix carefully. Figure 1-3A preheating pipeline for a generator set includes a base frame 1 for mounting the generator set. A preheating pump 2 is mounted on the base frame 1. A preheating pipeline is installed at the interface of the preheating pump 2. The preheating pipeline includes a hot water pipeline 3 and a cold water pipeline 4. The pipeline is made of 304 stainless steel, which has the characteristics of strong corrosion resistance, high strength, strong environmental adaptability, and long service life. The hot water pipeline 3 includes a first conduit 31 and a hot water pipe 32, which are connected by an elbow. The hot water pipe 32 is connected by a tee joint and an elbow. A first hot water connection pipe 33 and a second hot water connection pipe 34 are connected, and the first hot water connection pipe 33 and the second hot water connection pipe 34 are respectively connected to the hot water ports on the two engine units; the cold water pipeline 4 includes a second conduit 41 and a cold water pipe 42, which are connected by an elbow.

[0026] The above structure enables one preheating pump 2 to preheat two units simultaneously, and the two units can be controlled independently, increasing flexibility, reducing the installation of energy-consuming equipment such as pipes, valves, and preheating pump 2, optimizing the pipeline layout, making the pipeline simpler, reducing initial construction costs and space occupation, simplifying the layout in space-constrained places, reducing long-term operating costs, and the entire pipeline is detachable, facilitating later maintenance. The overall structure is stable and has certain practical value.

[0027] Hot water flow: After the preheating pump 2 is started, hot water flows out from the preheating pump 2, passes through the first conduit 31, hot water pipe 32, first hot water connecting pipe 33, second hot water connecting pipe 34, elbows, tee joints and other pipeline components, and reaches the hot water port of the engine unit to enter the engine. The hot water circulates in the engine, transferring heat to the engine components, raising the engine temperature and reducing wear during cold starts.

[0028] Cold water flow: The water cooled inside the engine (water whose temperature has been relatively reduced can be regarded as "cold water") flows out from the cold water port, returns to the preheating pipeline system, and enters the preheating pump 2 through the first cold water connection pipe 43, the second cold water connection pipe 44, the cold water pipe 42, and the second conduit 41, where it is heated again by the preheating pump 2 to form a cycle.
