Description

Technical Field

[0001] This utility model relates to the field of deaerator cap anti-clogging technology, specifically a deaerator anti-clogging foreign object device. Background Technology

[0002] A deaerator is designed into the dry quenching coke steam-water system. Its main purpose is to remove oxygen and other corrosive gases from the boiler feedwater, prevent corrosion of the steam-water system equipment, ensure safe and stable operation of the equipment, guarantee steam quality, and improve the operating efficiency of the steam-water system. The deaerator is a thermal deaerator, which utilizes the characteristic that "the solubility of gases in water decreases as water temperature increases." By heating the feedwater to near its boiling point, dissolved oxygen and other gases in the water escape, thereby achieving the purpose of deaeration.

[0003] Because the heating steam rises from the bottom of the deaerator during operation, passes through the deaerator water tank and the screen, and directly enters the deaerator tower, the steam directly heats and washes the packing at the bottom inlet of the deaerator tower. The packing here is easily corroded, damaged, and partially detached due to long-term direct steam heating. Small pieces of packing fall directly through the screen into the deaerator water tank, often clogging subsequent pipelines and pumps. This requires processing after the dry quenching coke production is stopped, which seriously affects the normal production of dry quenching coke. Therefore, we propose a deaerator anti-clogging foreign object device. Utility Model Content

[0004] The purpose of this invention is to provide a device for preventing foreign objects from clogging a deaerator, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deaerator anti-clogging foreign object device, comprising:

[0006] An anti-clogging mesh frame is provided, with an anti-clogging mesh at the upper end and a through hole in the middle. An installation cylinder is welded to the upper surface of the through hole, and a stainless steel disc is welded to the top of the installation cylinder. A vent hole is provided on the upper surface of the stainless steel disc. A grid is provided inside the installation cylinder and extends to the lower surface of the installation cylinder. A support plate is provided through the middle of the grid, and an insertion hole is provided in the middle of the support plate. A through rod is provided inside the insertion hole.

[0007] Furthermore, the anti-blocking mesh is symmetrically arranged about the central axis of the anti-blocking mesh frame, and the stainless steel disc is welded to the anti-blocking mesh frame through the mounting cylinder.

[0008] Furthermore, the vent holes are symmetrically arranged about the central axis of the stainless steel disc, and the stainless steel disc is connected to the mounting cylinder through the vent holes and the grille.

[0009] Furthermore, the through rod forms a detachable structure with the support plate through the insertion hole, and the support plate and the grid form a telescopic connection.

[0010] Furthermore, a circular connecting plate is fixed to the top of the support plate, a groove is provided at the connection between the stainless steel disc and the connecting plate, an annular positioning groove is provided at the weld between the stainless steel disc and the mounting cylinder, and a sealing ring is placed on the inner side of the annular positioning groove.

[0011] Furthermore, the connecting disc and the groove have matching shapes and structures, and the stainless steel disc is connected to the support plate through the groove and the connecting disc.

[0012] Furthermore, the mounting cylinder is engaged with the stainless steel disc via an annular positioning groove, and the sealing ring forms a sealing structure between the mounting cylinder and the annular positioning groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the deaerator anti-blocking foreign object device is equipped with a stainless steel disc, which, through the vent hole, not only ensures that the deaerator steam enters the deaerator tower normally, but also effectively prevents a large amount of steam from directly heating and scouring the packing at the bottom inlet of the deaerator tower. This effectively alleviates the heating and scouring of the packing at the inlet of the deaerator tower by the introduced steam, effectively extends the service life of the packing inside the deaerator tower, extends the normal deaerator deaerator operation time, and thus extends the continuous dry quenching coke production operation time.

[0022] Working principle: For this type of deaerator anti-clogging foreign object device, steam enters the installation cylinder 4 from the deaerator water tank through the perforation 3 in the anti-clogging mesh frame 1. The installation cylinder 4 is equipped with a grid 7 to initially disperse the airflow. Then, the steam passes through the vent holes 6 on the stainless steel disc 5 welded to the top of the installation cylinder 4. The vent holes 6 are evenly distributed in multiple rings to effectively disperse the steam flow and avoid concentrated scouring of the packing at the bottom of the deaerator. The stainless steel disc 5 is engaged and positioned with the installation cylinder 4 through the annular positioning groove 13, and the sealing performance is enhanced by the sealing ring 14.
