Description

Technical Field

[0001] This utility model relates to the field of waste incineration equipment technology, and in particular to a cooling tower for an easy-to-maintain waste incineration cooling system. Background Technology

[0002] For a long time, insufficient attention has been paid to cooling towers in the circulating water systems of waste incineration plants, with the perception that their maintenance is too arduous and complex. Due to a lack of awareness of the energy-saving potential of cooling towers, many power plants neglect their maintenance and supervision, and invest insufficiently in their retrofitting. This results in reduced cooling capacity, higher outlet water temperatures, decreased condenser vacuum, and reduced unit economics. Furthermore, existing cooling towers are often difficult to maintain, requiring cleaning of the water distributors inside the tower to prevent dust accumulation from affecting cooling performance. Therefore, structural modifications to the cooling towers are urgently needed to address this issue. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides an easy-to-maintain cooling tower for a waste incineration cooling system. The tower includes a cooling tower body, an air inlet mechanism, and a cooling mechanism. The cooling mechanism is located inside the cooling tower body, and the air inlet mechanism is located at the top of the cooling tower body. An air inlet dust removal device is provided on one side of the cooling tower body. This device includes a dust removal box with a removable cover, a fan, an air inlet pipe, an air supply pipe, a cleaning water tank, a water pump, a water delivery pipe, an atomizing nozzle, a drain pipe, and a solenoid valve. The dust removal box is located on the outer wall of the cooling tower body, and the cleaning water tank is located on one side of the cooling tower body. The cleaning water tank is connected to the dust removal box via the water supply pipe and the water pump. The air inlet mechanism is connected to the dust removal box via the air supply pipe. Both ends of the air inlet pipe are connected to the fan and the dust removal box, respectively. The atomizing nozzle is located at the end of the water supply pipe and inside the dust removal box. The drain pipe is connected to the bottom of the dust removal box, and the solenoid valve is located on the drain pipe.

[0004] By adopting the above technical solution, and by setting up an air intake dust removal device including a dust collection box, fan, air inlet pipe, air supply pipe, cleaning water tank, water pump, water delivery pipe, atomizing nozzle, drain pipe, and solenoid valve, the cooling air enters from the air inlet pipe and is then cleaned by the cleaning water tank, water pump, and atomizing nozzle in the dust collection box before entering the cooling tower. This ensures the cleanliness of the air entering the cooling tower and minimizes the rate of dust accumulation on the water distributor of the cooling tower, thereby avoiding affecting the cooling effect of the water distributor and effectively improving the cooling effect of the cooling tower.

[0005] A further feature of this invention is that a slot is provided at the bottom of the dust collection box, a filter screen is provided in the slot, and a baffle is fixedly provided on the box cover, with the baffle aligned with the slot.

[0006] By adopting the above technical solution, since a slot is provided at the bottom of the dust collection box, and a filter screen is provided in the slot, and a baffle is fixed on the box cover, the position of the baffle is aligned with the slot. The water mist combined with dust can be blocked by the baffle and the filter screen, so that the water mist liquefies into liquid on the baffle and the filter screen and flows down. At the same time, the amount of moisture carried by the air entering the cooling tower can also be reduced. In addition, the filter screen can be removed and cleaned regularly by opening the cover, which greatly reduces the difficulty of maintenance.

[0007] A further feature of this invention is that a level gauge is provided on the side wall located at the bottom of the dust collection box.

[0008] Using the above technical solution, since a level gauge is installed on the side wall at the bottom of the dust removal box, when the water level in the dust removal box reaches a certain depth, the solenoid valve of the drain pipe opens to discharge the water that has absorbed the dust.

[0009] A further feature of this invention is that an air outlet is provided on the outer side wall of the cooling tower body near the bottom, an air outlet is provided on the air outlet, an air outlet duct is provided inside the air outlet duct for auxiliary ventilation, and a removable filter screen is provided at the inlet of the air outlet duct.

[0010] By adopting the above technical solution, an air outlet is provided on the outer side wall of the cooling tower body near the bottom, an air outlet is provided on the air outlet, an air outlet duct is provided inside the air outlet duct for auxiliary exhaust, and a removable filter screen is provided at the inlet of the air outlet duct. The fan prevents outside air from flowing into the tower from the air outlet, and the filter screen further reduces the amount of dust entering the tower. Attached Figure Description

Detailed Implementation

[0015] like Figure 1-3 As shown, a maintenance-friendly waste incineration cooling system cooling tower includes a cooling tower body 1, an air inlet mechanism 2, and a cooling mechanism 3. The cooling mechanism is located inside the cooling tower body, and the air inlet mechanism is located at the top of the cooling tower body. An air inlet dust removal device 4 is provided on one side of the cooling tower body. The air inlet dust removal device includes a dust removal box 6 with a removable cover 5, a fan 7, an air inlet pipe 8, an air supply pipe 9, a cleaning water tank 10, a water pump 11, a water supply pipe 12, an atomizing nozzle 13, a drain pipe 14, and a solenoid valve 15. The dust removal box is located on the outer wall of the cooling tower body, and the cleaning water tank is located on one side of the cooling tower body. The cleaning water tank is connected to the dust removal box through the water supply pipe and the water pump. The air inlet mechanism is connected to the dust removal box through the air supply pipe. The two ends of the air inlet pipe are connected to the fan and the dust removal box, respectively. The atomizing nozzle is located at the end of the water supply pipe and inside the dust removal box. The drain pipe is connected to the bottom of the dust removal box, and the solenoid valve is located on the drain pipe.

[0016] By installing an air intake dust removal device that includes a dust collector, fan, air inlet duct, air outlet duct, cleaning water tank, water pump, water supply pipe, atomizing nozzle, drain pipe, and solenoid valve, the cooling air enters through the air inlet duct and is then cleaned by the cleaning water tank, water pump, and atomizing nozzle within the dust collector to remove dust from the air before it enters the cooling tower. This ensures the cleanliness of the air entering the cooling tower and minimizes the rate of dust accumulation on the water distributor, thus avoiding any impact on the cooling effect of the water distributor and effectively improving the cooling efficiency of the cooling tower.

[0017] The dust collection box has a slot 16 at the bottom, a filter screen 17 is installed in the slot, and a baffle 18 is fixed on the box cover, the position of the baffle being aligned with the slot.

[0018] Because a slot is located at the bottom of the dust collection box, and a filter screen is installed in the slot, and a baffle is fixed on the box cover, with the baffle aligned with the slot, water mist combined with dust can be blocked by the baffle and the filter screen, causing the water mist to liquefy into liquid and flow down. At the same time, it can also reduce the amount of moisture carried by the air entering the cooling tower. In addition, the filter screen can be removed for regular cleaning by opening the cover, greatly reducing the difficulty of maintenance.

[0019] A level gauge 19 is installed on the side wall at the bottom of the dust collection box.

[0020] Because a level gauge is installed on the side wall at the bottom of the dust collector, when the water level in the dust collector reaches a certain depth, the solenoid valve of the drain pipe opens to discharge the water that has absorbed the dust.

[0021] An air outlet 20 is provided on the outer wall of the cooling tower body near the bottom. An air outlet duct 21 is provided on the air outlet. A fan 22 for auxiliary ventilation is provided inside the air outlet duct. A removable filter screen 23 is provided at the inlet of the air outlet duct.

[0022] An air outlet is located near the bottom on the outer wall of the cooling tower body. An air outlet duct is provided on the air outlet. A fan for auxiliary ventilation is provided inside the air outlet duct. A removable filter screen is provided at the inlet of the air outlet duct. The fan prevents outside air from flowing into the tower from the air outlet, and the filter screen further reduces the amount of dust entering the tower.
