The purification mechanism not only can purify air, but also can be provided with a cooling function, and can purify and cool air simultaneously, so that the air flowing back to the capacitance compensation control cabinet 10 is cleaner and cooler, and the operation environment in the cabinet is better.

In addition, through setting up venturi jet pipe 30 for the air can be circulated, also makes this cooling dust pelletizing system can set up a plurality ofly in parallel, and a plurality of parallelly connected settings are realized more easily. The explanation of the plurality of parallel arrangement refers to the parallel arrangement of the cooling and dedusting systems of the plurality of capacitance compensation control cabinets, which is easier to realize. Because the cooling dust pelletizing system of each capacitance compensation switch board is equipped with a venturi jet pipe 30, every venturi jet pipe 30 links to each other with the air supply through its entry pipe section 31, makes the air supply link to each other with the cooling dust pelletizing system of each capacitance compensation switch board conveniently easily like this, just also makes the cooling dust pelletizing system of a plurality of capacitance compensation switch boards arrange side by side and realize easily. Furthermore, the air can be simultaneously supplied to the cooling and dedusting systems of a plurality of capacitance compensation control cabinets through a total air source.

In some preferred embodiments, a plurality of capacitance compensation control cabinets are arranged in parallel, and the inlet circular pipe section 31 of the temperature reduction and dust removal system of each capacitance compensation control cabinet is connected with an air source.

Further, the air source can be a compressed air supply system or a fresh air supply system. The gas source is delivered to the inlet pipe section 31 through a pipeline. Correspondingly, the air source can deliver compressed air or normal pressure air with accelerated flow rate. Compressed air is preferred, and the pressure of the compressed air does not need to reach high pressure, and the air in the venturi jet pipe 30 can be driven to flow only by pressurizing the compressed air to enable the air to flow.

In some preferred embodiments, the purification mechanism comprises a purification cartridge 51, a top end cap 54, a bottom conical end cap 55, a water supply pipe 52, a water discharge pipe 53;

the top end cover 54 is buckled at the top end of the purifying cylinder body 51;

the bottom conical end cover 55 is buckled at the bottom end of the purification cylinder body 51; and the purifying cylinder body 51, the top end cover 54 and the bottom conical end cover 55 are sealed to form an inner cavity (not marked in the figure);

the upper water pipe 52 is connected with the top end cover 54 and is communicated with the inner cavity;

the drain pipe 53 is fixedly connected with the middle part of the bottom conical end cover 55 and is communicated with the inner cavity;

In some preferred embodiments, the mixing outlet pipe 60 is formed with a "concave" section a and forms a low point of drainage. The concave section a is provided to collect the moisture in the gas discharged from the mixing outlet duct 60, so as to accelerate the formation of water drops, so that the moisture in the mixing outlet duct 60 is collected at the concave section a as much as possible, and the moisture in the mixing outlet duct 60 is further promoted to be discharged from the drainage low point.

In some preferred embodiments, an automatic drain valve 61 of a mechanical type is further included, and the automatic drain valve 61 is installed at a drain low point of the "concave" section a. The accumulated water is automatically discharged by the automatic water discharge valve 61, and the automatic water discharge valve 61 may be mechanical or electric.

In some preferred embodiments, the conical top of the bottom conical end cap 55 is at the bottom end, and the drain pipe 53 is connected to the conical top of the bottom conical end cap 55. The cone top faces downwards, so that water can be conveniently collected and drained.

The PVC pipe can reduce cost, effectively block heat exchange of external air, and avoid heat exchange between external high-temperature air and air in the pipe.

In some preferred embodiments, a temperature sensor and a controller are also included, the temperature sensor being disposed within the capacitance compensation control cabinet 10 and electrically connected to the controller.

When the temperature sensor detects that the temperature is higher than a set value, the controller controls the air source to provide air, so that the air in the venturi jet pipe 30 flows, and the cooling and dedusting system of the whole capacitance compensation control cabinet operates.

In some preferred embodiments, the suction pipe 33 of the venturi jet pipe 30 is provided with a solenoid valve, and the solenoid valve is electrically connected with the controller. The electromagnetic valve is arranged on the venturi jet pipe 30 to realize independent control; when the air source corresponds to the cooling and dedusting systems of a plurality of capacitance compensation control cabinets at the same time, each venturi jet pipe 30 corresponds to one electromagnetic valve, so that the independent operation and independent ventilation of the cooling and dedusting systems of the capacitance compensation control cabinets are realized.

In some preferred embodiments, the controller is electrically connected to the delivery system of the gas source to control the opening or disconnection of the branches of the gas source.

In other preferred embodiments, the purification mechanism is an electric air purifier.
