Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization and denitration spray towers, in particular to a corrosion-resistant desulfurization and denitration spray tower. Background Art

[0002] At present, after the hollow balls inside the spray tower have been used for a period of time, the adhesion and accumulation of highly viscous pollutants can easily lead to obstruction of gas flow inside the spray tower, affecting the working efficiency of the desulfurization and denitrification spray tower. Therefore, the hollow balls in the spray tower need to be cleaned regularly.

[0003] However, when cleaning the hollow balls in the existing spray tower structure, it is necessary to first remove the hollow balls on the filter plate inside the spray tower by observation and then clean them. Since the diameter of the spray tower is relatively large, it is difficult to remove the hollow balls that are far away from the observation hole. For this reason, the existing spray tower structure is optimized to facilitate the removal of the hollow balls in the tower for cleaning. Utility Model Content

[0004] In view of the problems and shortcomings in the prior art, the utility model provides a corrosion-resistant desulfurization and denitrification spray tower.

[0005] The technical solution of this utility model is as follows:

[0006] A corrosion-resistant desulfurization and denitrification spray tower comprises a cylindrical tower body, a plurality of observation holes connected to the tower body are vertically arranged on the side wall, and two filter plates are vertically arranged inside the tower body; the tower body is characterized in that:

[0007] There is also a ball collecting device inside the tower body, which includes:

[0008] The motor is fixed on the side wall of the tower body, and the output shaft extends horizontally into the tower body;

[0009] A transmission assembly, comprising a driving shaft, a first driven shaft and a second driven shaft, wherein one end of the driving shaft is connected to the motor output shaft, and the other end is connected to the driving gear, the first driven shaft and the second driven shaft are respectively connected to the filter plates adjacent to each other vertically and rotatably, the upper and lower parts are coaxial and intersect at the driving gear, and the upper and lower adjacent parts are respectively connected to the first driven gear and the second driven gear meshing with the driving gear;

[0010] The ball collector is connected to the first driven shaft and the second driven shaft and rotates therewith, and is located above the filter plate. It has a partition extending along the radial direction of the tower body, and a plurality of partitions are evenly distributed in the circumferential direction.

[0011] Working principle: When it is necessary to take out the hollow ball from the body for cleaning, start the motor, and the motor converts the circular motion around the horizontal axis into the circular motion around the vertical axis through the transmission assembly, thereby driving the first drive shaft and the second drive shaft connected to the two adjacent filter plates to rotate, and the first drive shaft drives the ball collector connected thereto to rotate, and the ball collector is divided into multiple fan-shaped areas opening outward by the partition. When the center of each fan-shaped area rotates to the position of the observation hole, the motor stops rotating, and the staff can take out the hollow ball inside at this time. The motor starts again to rotate the next fan-shaped area separated by the partition to the position of the observation hole, which is convenient for the staff to take out the hollow ball inside. The interval time of starting and stopping the motor can be determined according to the experiment at this time, and the start-stop button can also be set at the observation hole position. In this way, the staff only needs to salvage the hollow ball in the fan-shaped area in the front center of the tower body, and there is no need to directly salvage the hollow ball in the rear center of the tower body, which reduces the difficulty of taking out the hollow ball and improves the maintenance efficiency.

[0012] According to a specific embodiment, the driving gear, the first driven gear, and the second driven gear are helical cylindrical gears or spur bevel gears.

[0013] Furthermore, the height of the partition is equal to 2-5 times the outer diameter of the hollow ball. The number of the partitions is 3-6, the purpose of which is to reduce the range of the hollow ball to be salvaged at one time and reduce the difficulty of salvaging. Preferably, the number of the partitions is 4.

[0014] Furthermore, a filter plate brush is provided at the bottom of the partition, and the bottom surface of the filter plate brush contacts the top surface of the filter plate. Specifically, the filter plate brush is detachably connected to the bottom of the partition.

[0015] A spray mechanism is also provided on one side of the tower body, including a medicine pool connected to the tower body, a pump fixed on the water pool, a spray pipe connected to the pump and extending upward above the filter plate inside the tower body, and a plurality of nozzles arranged on the spray pipe.

[0016] The beneficial effects of the utility model are:

[0017] A ball collecting device is arranged in the tower body, and the ball collecting device comprises a motor, a transmission assembly and a ball collector. The motor and the rotating assembly drive the first driven shaft and the second driven shaft connected to the two upper and lower adjacent filter plates to rotate, thereby driving the ball collector connected thereto to rotate. The ball collector is divided into a plurality of sector-shaped areas by partitions radially radiating along the tower body. Each sector-shaped area forms a small ball collecting area, which is driven by the motor and the transmission assembly to rotate to the observation hole in turn. The staff only needs to salvage the hollow ball from the side close to the observation hole, thereby reducing the difficulty of salvaging the hollow ball and improving the efficiency of cleaning and maintenance of the spray tower.
