Description

Technical Field

[0001] The utility model relates to the technical field of demisting. Background Art

[0002] At present, in various power generation or central air conditioning systems, circulating cooling water towers are essential equipment for reducing the temperature of circulating cooling water. However, due to the structure, the cold air exchanges heat with water inside the cooling tower. While the water temperature is reduced, saturated hot and humid air is generated. After the hot and humid air is blown out of the cooling tower by the fan, it mixes with the external cold air, cools and condenses to form mist containing many tiny liquid particle groups. Especially when the ambient temperature is low, the mist can rise 20 to 30 meters, resulting in a large waste of water resources. With the improvement of environmental protection requirements, water-saving and demisting of mechanical ventilation cooling towers are becoming more and more important. Summary of the invention

[0003] In order to solve the technical problem of water resource waste caused by rising mist during cooling, the utility model provides a water-saving demister.

[0004] The technical solution adopted by the utility model to achieve the above-mentioned purpose is:

[0005] A water-saving demister has a baffle plate installed obliquely in an outer shell, a conical wire mesh cap installed on the inner top of the outer shell, and the baffle plate on the baffle plate is arranged obliquely.

[0006] The deflector grating includes a first deflector grating and a second deflector grating. The first deflector grating and the second deflector grating are both installed on the inner wall of the shell. The first deflector grating and the second deflector grating are staggered, and the first deflector grating and the second deflector grating have the same inclination angle relative to the central axis.

[0007] The baffle is a hole-type plate.

[0008] The inclination angle of the baffle plate is 50±10°, and the inclination angle of the baffle plate is 20±10°.

[0009] The baffle is a long hole plate or a circular hole plate.

[0010] The wall plate of the shell is a patterned plate, and one side of the patterned plate is located inside the shell, and a gap is provided between the inner wall of the shell and the baffle.

[0011] A water return baffle is installed at the bottom of the shell, and a gap is arranged between the water return baffle and the bottom edge of the shell.

[0012] A support is installed outside the shell.

[0013] The shell and the conical wire mesh cap are made of stainless steel or glass.

[0014] The advantages of the utility model compared with the prior art are:

[0015] As the mist enters from the bottom of the square shell and rises, it passes through multiple baffle plates and finally reaches the conical wire mesh cap. The mist contacts the baffle plates and the conical wire mesh cap, and the moisture in the mist accumulates on the baffle plates and the conical wire mesh cap. When it accumulates to a certain extent, the accumulated water droplets will slide along the inclined baffle plates and the conical wire mesh cap to the bottom of the square shell, thereby realizing the recovery of moisture in the mist. The water collection rate is high, the structure is simple, and the manufacturing cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model provides a water-saving demister, such as Figure 1 As shown, the outer shell 1 is square, and the baffle plate 2 is installed obliquely in the outer shell 1. The baffle plate 2 includes a first baffle plate 7 and a second baffle plate 8. The first baffle plate 7 and the second baffle plate 8 are both installed on the inner wall of the outer shell 1. The first baffle plate 7 and the second baffle plate 8 are staggered, and the first baffle plate 7 and the second baffle plate 8 have the same inclination angle relative to the central axis. By arranging multiple groups of baffle plates 2, the blocking of fog inside the outer shell 1 is improved, and the contact time and release area between the fog and the baffle plate 2 are increased.

[0022] The baffle plate 6 of the baffle grid plate 2 is a hole plate, such as Figure 3-4As shown, it can be a long strip hole plate or a circular hole plate, the wall plate of the shell 1 is a patterned plate, and the patterned side of the patterned plate is located inside the shell 1, and a gap is provided between the inner wall of the shell 1 and the baffle 6 to facilitate the passage of water droplets. The hole plate and the patterned plate can present many edges inside the shell 1. By utilizing the properties of the water surface tension, the moisture in the mist can be easily adsorbed to these edges. When the moisture accumulates to a certain extent to form water droplets, the water will fall onto the return water baffle 4 at the bottom of the square shell, and a gap is provided between the return water baffle 4 and the bottom edge of the shell 1 to facilitate water recovery.

[0023] The baffle plate 6 of the baffle plate 2 is tilted, the tilt angle of the baffle plate 2 is 50±10°, and the tilt angle of the baffle plate 6 is 20±10°. Due to the surface tension of water, the weight of the water droplets must reach a certain level before they can fall. By tilting the baffle plate 2 and the baffle plate 6, the water droplets can converge to the bottom of the baffle along the tilt surface of the baffle plate 6, and large water droplets can fall quickly.

[0024] like Figure 2 As shown, a conical wire mesh cap 5 is installed on the top of the housing 1, and the conical wire mesh cap 5 blocks the mist rising to the top of the square housing, further improving the water collection rate of the water in the mist. The housing 1 and the conical wire mesh cap 5 are made of corrosion-resistant materials with smooth surfaces, and the housing 1 and the conical wire mesh cap 5 are made of stainless steel or glass, which reduces the adsorption of water droplets on the housing 1 and the conical wire mesh cap 5, accelerates the falling of water droplets, improves the water collection rate, and improves the service life of the defogger.

[0025] A support 3 is installed outside the housing 1 for supporting and installing the demister.
