Description

Technical Field

[0001] This utility model belongs to the technical field of waste gas generator sets, and in particular relates to a multi-fan cooling water tank for generator sets with a wet curtain. Background Technology

[0002] In my country, waste gas is increasingly valued and vigorously developed as a usable energy source. Using waste gas for power generation can not only turn waste into treasure and meet the electricity needs of production and daily life, but also reduce environmental pollution and greenhouse gas emissions.

[0003] The 12V190 engine is commonly used in waste gas power generation. It is typically equipped with a horizontal multi-fan radiator, which, together with the engine's internal water channels, forms a dual-circuit cooling system: a "high-temperature cooling system" and a "low-temperature cooling system." The high-temperature cooling system is used to cool components operating in high-temperature areas (engine block, cylinder head) and the oil cooler; the low-temperature cooling system is used to cool components operating in low-temperature areas (intercooler).

[0004] The horizontal multi-fan radiator has eight fans, installed on top of the radiator core assembly. The radiator core assembly is divided into high-temperature and low-temperature radiator cores, with the high-temperature cores installed on top and the low-temperature cores on the bottom. The radiator core assembly is connected to the unit's internal cooling system via inlet and outlet pipes. Through fan operation, cooler ambient air flows upwards, penetrating the low-temperature and high-temperature radiator cores sequentially, achieving forced cooling of the cooling water to provide the necessary cooling water for the generator set during operation.

[0005] However, during the hot summer months, ambient air temperatures often exceed the generator set's design temperature. Improper installation of the horizontal multi-fan radiator, or poor airflow, can also lead to insufficient cooling capacity in the generator set's cooling system. This manifests as oil temperatures exceeding 85°C in the oil pan and excessively high exhaust gas inlet temperatures, failing to meet the unit's cooling requirements. This results in insufficient generator power output or oil temperature alarms causing shutdowns. Redesigning and replacing the cooling system is time-consuming, labor-intensive, and impractical, often resulting in reduced generator power output, wasted exhaust gas, and decreased power generation. Furthermore, the radiator's height exceeds 1.5 meters, requiring external ladders for maintenance of the horizontal multi-fan radiator's fans, which is time-consuming and labor-intensive. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a multi-fan cooling water tank with a wet curtain that can effectively meet the cooling needs of generator sets and increase power generation.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figures 1-3 As shown, this utility model provides a multi-fan cooling water tank for generator sets with a wet curtain, including a support frame, a heat dissipation component is provided on the upper part of the support frame, a wet curtain component is provided inside the support frame, and a cooling water tank controller is provided outside the support frame.

[0025] The heat dissipation assembly includes a heat dissipation box, at least one set of fans is provided on the upper part of the heat dissipation box, a heat dissipation core is provided inside, and a water temperature sensor is connected to the end of the heat dissipation core.

[0026] The evaporative cooling pad assembly includes a water storage tank, on which the evaporative cooling pad is mounted. Side frames fixed to the water storage tank are mounted on both sides of the evaporative cooling pad. An upper load-bearing heat dissipation box fixed to the side frames is mounted on the upper part of the evaporative cooling pad. A water pump and a float valve are installed inside the water storage tank. A longitudinally arranged water supply pipe is mounted on the water pump, and a water distribution pipe is installed at the end of the water supply pipe furthest from the water pump.

[0027] The heat dissipation core consists of a high-temperature heat dissipation core and a low-temperature heat dissipation core from top to bottom.

[0028] The support frame is equipped with a folding pedal.

[0029] The top of the heat sink is equipped with a handle.

[0030] Based on the above description, the specific positional relationship of the aforementioned components is as follows:

[0031] The support frame 1 is bolted to the lower surface of the heat sink 8; the heat sink core is a cuboid and is bolted into the heat sink 8. A handle 3 is fixedly connected to one side of the upper surface of the heat sink 8; the support frame 1 is a frustum, and a folding pedal 5 is installed on the outer wall of the support frame.

[0032] Four holes are drilled in the support frame of the horizontal multi-fan water tank, two folding pedals are installed, and a handle 3 is installed on the upper surface of the heat sink 8. The operator can safely climb onto the horizontal multi-fan water tank to add water or perform various maintenance tasks by stepping on the folding pedals installed on the support frame and holding the handle. This solves the problem of having to use an external ladder to climb up when performing fan maintenance and other tasks, which is time-consuming and laborious.

[0033] The evaporative cooling pad assembly 9 is mounted on the support frame 1, creating a sealed space below the radiator. Air is blown upwards from the fan 4, creating a negative pressure below the radiator. The air surrounding the radiator, cooled by the evaporative cooling pad assembly 9, enters the lower part of the radiator under this pressure, passing through the low-temperature cooling core 7 and the high-temperature cooling core 6 in sequence, thus achieving forced cooling of the cooling water to provide the necessary cooling water for the generator set during operation.

[0034] like Figure 2 , 3 The evaporative cooling pad assembly shown includes a frame 92, an upper support heat dissipation box 93, a water storage tank 91, an evaporative cooling pad 94, a water supply pipe 97 and a water distribution pipe 98, a float valve 95, and a water pump 96. The water pump is installed inside the water storage tank on one side via a suction cup. The upper side of the water pump is connected to the water supply pipe 96, and the water supply pipe 96 extends into the upper support heat dissipation box and connects to the water distribution pipe 98. The lower surface of the water distribution pipe 98 has multiple spray holes evenly spaced. The evaporative cooling pad 96 is a porous honeycomb material used for evaporative cooling. It is 100-150mm thick and is made of specially made fiber paper with good water absorption. The paper is pressed into a corrugated board and then layered and bonded into a plate shape, allowing airflow and water flow to cross and maximize water-air contact. It also has good corrosion resistance.

[0035] The frame bracket 92, the upper support heat dissipation box 93, and the water storage tank 91 are made of bent stainless steel plates and are connected by welding to fix the wet curtain 94 in the middle. A float valve is installed on one side of the inside of the water storage tank through a fixing hole, and the float valve is connected to the softened water system of the power plant.

[0036] Water from the storage tank is pumped through the supply pipe to the distribution pipe 98, and then sprayed onto the evaporative cooling pad 94 through the nozzles of the distribution pipe 98. The water then flows back into the storage tank 91 under the influence of gravity. The evaporative cooling pad 94 prolongs the residence time of the air, which helps to lower the air temperature and also filters and purifies the air, removing dust particles.

[0037] The float valve uses a hollow ellipsoidal float. The buoyancy of the float on the water surface causes the rotation of a lever, thus opening and closing the float valve. When the water level in the storage tank drops, the float, under the influence of gravity, follows the water level and opens the float valve, allowing softened water from the power station to flow into the storage tank, achieving automatic water replenishment. When the float rises to a certain position, the lever connected to one side of the float rotates, closing the float valve and blocking the inlet, completing the automatic water replenishment of the storage tank.

[0038] The fan 4 is used in conjunction with the wet curtain assembly. By blowing air upwards from the fan 4, a negative pressure is created below the water tank. The air around the water tank is cooled by the wet curtain assembly and enters the bottom of the water tank under the action of air pressure. It then passes through the low-temperature heat dissipation core 7 and the high-temperature heat dissipation core 6 in sequence, thereby achieving forced cooling of the cooling water and effectively reducing the temperature of the cooling water.

[0039] The specific embodiments of this utility model are described in further detail below.

[0040] When the ambient temperature is not very high and the cooling capacity of the radiator is sufficient, the radiator controller detects that the water temperature sensor temperature does not exceed the set temperature and cuts off the power to the water pump 96, preventing water supply to the evaporative cooling pad. Only through the operation of eight fans, ambient air passes through the evaporative cooling pad and then sequentially through the low-temperature and high-temperature cooling cores from bottom to top, achieving forced cooling of the cooling water to provide the cooling water required for the generator set's operation. The evaporative cooling pad is made of porous material with low resistance of approximately 20 Pa, which does not affect the heat dissipation effect.

[0041] During hot summer weather, if the cooling capacity of the radiator is insufficient and the radiator controller detects that the temperature of the water temperature sensor 2 exceeds the set temperature, it will activate the power supply to the water pump 96. The water pump 96 will then transport water from the storage tank to the distribution pipe 98 via the supply pipe 97, and spray it onto the wet curtain through the nozzles of the distribution pipe 98. This ensures that the water flows evenly across the surface of the wet curtain, forming a water film. Under the influence of gravity, the water flows back into the storage tank 91 through the wet curtain, creating a continuous cycle. The wet curtain is made of porous material, which helps retain moisture. When air passes through these moist pores, the water evaporates, absorbing heat from the air. This lowers the temperature of the outflowing air by approximately 10°C. The cooled air then passes through the low-temperature radiator core and the high-temperature radiator core sequentially from bottom to top, achieving forced cooling of the cooling water to provide the cooling water required for the generator set to operate. The water pump circulates water to the top of the wet curtain, ensuring even distribution and keeping it moist. The fan pushes air through the wet curtain, promoting evaporation. In this way, the entire system works in concert to achieve a cooling effect. By reducing the temperature of the outside air, the temperature of the cooling water can be reduced, the oil temperature in the oil pan can be lowered to below 85°C, and the intake temperature of the exhaust gas can be reduced to meet the cooling requirements of the unit, allowing the generator set to operate at full power.

[0042] The newly added wet curtain unit consumes very little power during operation, but the generator set can operate at full power, increasing the power generation by about 100 kilowatts per hour. Based on a month of high-temperature summer operation, it can generate an additional 70,000 kilowatt-hours of electricity, thus increasing the economic benefits of the power plant.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
