Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower sewage discharge, in particular to a cooling tower sewage discharge machine. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the heat exchange between water and air flow to generate steam. The steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer. It dissipates the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature through evaporative heat dissipation to ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower.

[0004] By adopting the above technical scheme, the entire cooling and ventilation process of the cooling tower relies on water spray as the source power, thereby realizing atomization cooling and ventilation. The whole process does not consume electrical energy and does not require energy supply equipment such as motors, which greatly reduces the overall energy consumption of the equipment, streamlines the internal structure of the equipment, and greatly improves its overall cooling efficiency. However, the above technical scheme cannot discharge the sludge at the bottom of the cooling tower. If there is too much sludge, it will cause the cooling tower to store water unsmoothly and the water quality will be poor, resulting in reduced heat exchange efficiency, increased system energy consumption and other problems.

[0005] Therefore, those skilled in the art provide a cooling tower blowdown machine to solve the problems raised in the above background technology. Utility Model Content

[0024] The sewage discharge mechanism 2 includes a sewage box 201, the upper surface of the sewage box 201 is fixedly connected to the bottom surface of the shell 1, and the inner bottom wall of the sewage box 201 is fixedly connected with a filter screen 202. The top end of the filter screen 202 penetrates the shell 1 and extends to the inside of the shell 1. A hot water pipe 5 is arranged inside the shell 1. The end of the hot water pipe 5 away from the shell 1 penetrates the shell 1 and extends to the outside of the shell 1. The outer surface of the hot water pipe 5 is fixedly connected with a plurality of nozzles 6. By providing the hot water pipe 5 and the nozzle 6, hot water can be evenly sprayed into small water droplets for heat conversion.

[0025] The bottom end of the filter screen 202 passes through the sewage tank 201 and is fixedly connected to a sewage pipe 203. One end of the sewage pipe 203 away from the sewage tank 201 is fixedly connected to an electronic induction valve 204. The outer surface of the hot water pipe 5 is fixedly connected to three square tubes 7. The left and right sides of each square tube 7 are fixedly connected to the inner wall of the outer shell 1. The square tubes 7 can support and fix the hot water pipe 5, so that the hot water pipe 5 cannot be shaken by wind, thereby increasing the service life of the hot water pipe 5.

[0026] The bottom surface of the sewage tank 201 is fixedly connected to a cold water pipe 205, and one end of the cold water pipe 205 away from the sewage tank 201 is fixedly connected to a cold water valve 206. The outer surface of the sewage tank 201 is fixedly connected to a detector 207, and the upper surface of the detector 207 is fixedly connected to a sewage detection needle 208. The inner wall of the outer shell 1 is fixedly connected to a filler 8, and a plurality of air inlet grilles 11 are provided on the outer surface of the outer shell 1. By providing the filler 8, the residence time of the circulating water can be prolonged and the heat exchange area can be increased. The air inlet grilles 11 can allow cold air to enter for heat conversion and then be discharged from the cooling tower through the rotation of the fan blades 14.

[0027] The end of the sewage detection needle 208 away from the detector 207 passes through the sewage tank 201 and the filter 202 in sequence and extends to the inside of the filter 202. The bottom surface of the detector 207 is fixedly connected with a cold water detection needle 209. The outer surface of the outer shell 1 is fixedly connected with five hoops 9. A water supply pipe 10 is arranged on the outside of the outer shell 1. The end of the water supply pipe 10 close to the outer shell 1 passes through the outer shell 1 and extends to the inside of the outer shell 1. The firmness of the outer shell 1 is increased by providing the hoop 9, so that the service life of the cooling tower is extended. The water supply pipe 10 can replenish the circulating water lost due to the discharged sewage.

[0028] The end of the cold water detection needle 209 away from the detector 207 passes through the sewage tank 201 and extends to the interior of the sewage tank 201. The front of the detector 207 is fixedly connected to a numerical meter 210. The bottom surface of one of the hoops 9 is fixedly connected to four supporting legs 12. The bottom end of each supporting leg 12 is fixedly connected to a base 13. The support legs 12 are provided to lift the cooling tower as a whole away from the ground, thereby preventing the outer shell 1 from being corroded by moisture at the ground due to long-term contact with the outer shell 1.

[0029] The working principle of the utility model is: first, the cooling tower body is fixed on the top of the base 13 through the support legs 12, and the material of the base 13 is preferably a concrete block, and then the rotating motor 3, the detector 207 and the electronic induction valve 204 are electrically connected through wires, and the hot water pipe 5 and the nozzle 6 are used to spray hot water on the inside of the cooling tower. At this time, the hot water contacts the air to evaporate water vapor. At this time, the power provided by the rotating motor 3 drives the fan blades 14 to rotate, and the cold wind passes through the air intake grille 11 to blow the evaporated water vapor out of the cooling tower through the rotation of the fan blades 14. When the hot water falls on the upper surface of the filler 8, the filler 8 increases the heat dissipation in the cooling tower, prolongs the residence time of the circulating water, and increases the heat exchange area. When the circulating water penetrates the filler 8, it falls on the bottom surface of the shell 1 and flows to the inside of the filter 202, and then the filter 202 can filter out the silt in the water and retain it in the inside of the filter 202. The cold water filtered by the filter 202 flows to the equipment that needs heat dissipation through the cold water pipe 205 for secondary heat dissipation. If the equipment that needs heat dissipation no longer works, The cold water pipe 205 can be closed by the cold water valve 206 to stop the water from flowing. The sewage detection needle 208 and the cold water detection needle 209 will continuously detect the water quality for 24 hours. The detected information is sent to the detector 207. The detector 207 calculates the information into data and presents it on the numerical table 210. Once the turbidity concentration of the water in the filter 202 is five to six times that of the cold water in the sewage tank 201, the detector 207 will send an opening signal to the electronic induction valve 204 to open the valve for sewage discharge. At this time, the sewage detection needle 208 continues to detect the water quality. If the turbidity concentration of the water in the filter 202 is less than 1.5 times the quality of the cold water in the sewage tank 201, the detector 207 will send a closing signal to the electronic sensor valve 204 to close the valve to stop the water. After several sewage discharges, the circulating water in the cooling tower will become less, and the cooling tower can be replenished with water through the water replenishment pipe 10. The cooling tower sewage machine can filter the impurities in the circulating water and automatically discharge them, ensuring the smooth flow of the circulating water, improving the water quality of the circulating water, making the heat exchange efficiency stable and saving system energy consumption.
