Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchange equipment and process equipment, and specifically relates to a frame-type demister. Background Art

[0002] The frame-type metal baffle cooler commonly used in existing air coolers uses stainless steel baffles, which are fixed by a frame extrusion fixation method. Figure 1 As shown, the lower reinforcement plate is fixed on the frame, and a water retaining plate is inserted into the groove of the reinforcement plate. A round steel is used to press the water retaining plate on the upper part, and the water retaining plate and the round steel are fixed by argon arc spot welding. During the construction process, the upper round steel is relatively thin, and the water retaining plate fixed in the middle is prone to overpressure and underpressure, and sometimes both situations occur at the same time. Overpressure causes the angle and shape of the fins to change, resulting in poor defoaming effect, and underpressure causes the retaining plate to loosen, causing vibration under the action of high-speed airflow, affecting the life of the defoamer. In addition, in order for the retaining plate to withstand the force of extrusion and in order to be welded with the upper fixed round steel, the retaining plate needs to have a certain rigidity and strength when designed, and the weldability must be good. The material needs to be stainless steel, the manufacturing cost is high, and the product weight is large. For this reason, a frame-type defoamer is designed to overcome the above problems.

[0016] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "horizontal" and "vertical" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention. They do not indicate or imply that the device or component referred to must have a specific direction and therefore should not be understood as a limitation on the present invention.

[0017] The utility model will be described in detail below with reference to the accompanying drawings: Figure 2-3 As shown, a frame-type demister comprises a demister body 1, wherein the demister body 1 is composed of an outer frame 2, a first reinforcing plate 3, a second reinforcing plate 4 and a plurality of demister baffles 5, wherein the first reinforcing plate 3 and the second reinforcing plate 4 are respectively provided with a plurality of recessed first slot holes 6 and second slot holes 7, and when the first reinforcing plate 3 and the second reinforcing plate 4 are aligned front and back and tightly assembled, a placement groove for installing the demister baffles 5 is formed at the recessed intersection between the corresponding first slot holes 6 and the second slot holes 7, and symmetrical outer frames 2 are respectively fixed on the left and right side surfaces of the first reinforcing plate 3 and the second reinforcing plate 4 that are tightly assembled, and the first reinforcing plate 3 and the second reinforcing plate 4 are limited and fixed by the left and right outer frames 2, thereby ensuring that the demister baffles 5 in the mounting holes are firmly fixed and will not shift during operation.

[0018] The first slot hole 6 on the first reinforcing plate 3 and the second slot hole 7 on the second reinforcing plate 4 have the same shape, and each corresponding first slot hole 6 and second slot hole 7 are cross-arranged (either left-right cross-arrangement or up-down cross-arrangement is possible), and the concave intersection between the first slot hole 6 and the second slot hole 7 is used to install and fix the defoaming baffle 5.

[0019] The defoaming baffle 5 is drawn from a long strip mold, one end of which is bent downward to form a hook-shaped bending portion 8, and the other end is a zigzag long strip structure, and a circular limiting protrusion 9 is arranged at one end of the long strip structure away from the bending portion 8, and the circular limiting protrusion 9 is inserted into the groove corresponding to the bottom of the first slot 6 of the first reinforcing plate 4 or the second slot 6 of the second reinforcing plate 4, so as to ensure that the defoaming baffle 5 will not fall out of the first slot 6 and the second slot 7. The first reinforcing plate 3 and the second reinforcing plate 4 are of the same size and both have an inverted "X" shape.

[0020] The defoaming baffles 5 are arranged in a single row, parallel and equidistantly, and are evenly distributed between the first reinforcing plate 3 and the second reinforcing plate 4.
