Description

Technical Field

[0001] The invention relates to the technical field of accident oil collecting pools in transformer substations, in particular to ventilation equipment used for accident oil collecting pools in transformer substations. Background Art

[0002] The function of the substation accident oil collection pool is to prevent the main transformer and other oil-filled electrical equipment from leaking oil and causing fires and other accidents. When an accident occurs, the oil will flow into the accident oil collection pool, and the air in the accident oil collection pool will be discharged at the same time. This requires the installation of a ventilation device on the top of the accident oil collection pool. The traditional ventilation device uses an ordinary ventilation pipe with a hook-shaped top. Since the ventilation pipe is exposed to the outside, rainwater can easily corrode the ventilation pipe, small animals and foreign objects can easily enter the ventilation pipe to cause blockage, and the oil in the oil pool can be easily contaminated. In addition, with the progress of society, people pay more and more attention to the monitoring of exhaust gas, and single-function ventilation equipment can no longer meet people's needs. Summary of the invention

The adsorption dust removal ring divides the cylinder into two chambers, one of which is close to the monitoring unit and the other is close to the channel. An opening is provided on the cylinder, and the opening is connected to the channel.

[0008] Furthermore, the adsorption dust removal ring includes an outer ring, an inner ring for the rotating rod to be inserted, and a plurality of metal rods for evenly dividing the ring body between the outer ring and the inner ring into a plurality of petal fan-shaped structures, and two adjacent metal rods form a petal fan-shaped structure, and in each of the fan-shaped structures, at least one petal of the fan-shaped structure is filled with adsorption cotton.

[0009] Furthermore, there are a plurality of adsorption dust removal rings, all of which are sleeved on the rotating rod, and each of the adsorption dust removal rings is arranged in parallel.

[0022] See also Figures 1 to 5 The embodiment of the present invention provides a ventilation device for the accident oil collecting pool of a substation, comprising an outlet pipe 3 with one end extending into the underground accident oil collecting pool, a monitoring unit for monitoring the concentration of the exhaust gas, and a dust removal mechanism 9 for removing oil molecules from the gas. The other end of the outlet pipe 3 extends into the monitoring unit, the monitoring unit is docked with the dust removal mechanism 9, and the dust removal mechanism 9 is provided with a channel 8 for the exhaust of the cleaned gas on the side away from the monitoring unit. In this embodiment, the concentration of the exhaust gas and the removal of the oil molecules in the gas can be monitored respectively by the monitoring unit and the dust removal mechanism 9. On the one hand, the exhaust gas is monitored, and on the other hand, the exhaust gas is purified, which is environmentally friendly. Specifically, the lower end of the outlet pipe 3 extends into the underground accident oil collecting pool, and the gas discharged from the pool enters the monitoring unit through the outlet pipe 3, and the concentration of the gas is monitored by the monitoring unit. Then the gas is passed from the monitoring unit to the dust removal mechanism 9, and is purified in the dust removal mechanism 9 to remove the oil molecules. The purified gas can be discharged from the device through the channel 8. In fact, after the gas passes through the above links, its sealing performance is obviously better than that of the existing system with only one ventilation pipe, which can prevent small animals and foreign objects from entering the ventilation pipe and blocking the ventilation pipe and polluting the oil pool.
