Description

Exhaust structure for circulating water cooler in large-scale equipment

Technical Field

The utility model relates to chemical equipment, in particular to an exhaust structure of a circulating water cooler in a large-scale device.

Background

The circulating water cooler in the large-scale equipment is more in quantity, and needs to exhaust periodically in the operation process so as to eliminate air resistance and improve heat exchange efficiency. The diameter of a large circulating water cooler in the large-scale tool reaches more than 1 meter, the ground clearance of the base is 2-3 meters, and part of the large circulating water cooler is positioned at the high position of the frame, so that the ascending exhaust potential safety hazard is very large, the risk of falling from the high position exists, the operation is very inconvenient, time and labor are wasted, and the cost of an operation platform is increased greatly. The problem of freezing prevention in winter caused by leading high-point exhaust to the ground exists, and the problem of high-point exhaust of the circulating water cooler brings great trouble to field operators.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems in the prior art, the utility model provides an exhaust structure for a circulating water cooler in a large-scale device.

The utility model provides an exhaust structure for maximization frock circulating water cooler, includes circulating water cooler's lower part is provided with circulating water inlet pipe the upper portion of circulating water cooler is provided with the circulating water wet return, the high-order department body of circulating water wet return with be connected with the bypath pipe between the body that is close to ground position on the circulating water inlet pipe, circulating water wet return and circulating water inlet pipe pass through the bypath pipe is linked together the position that is close to ground on the bypath pipe has concatenated first ooff valve be located on the lateral wall of bypath pipe be located second ooff valve is installed to position between first ooff valve and the circulating water inlet pipe, the second ooff valve is close to first ooff valve.

The working principle of the utility model is as follows: when the circulating water cooler operates, gas is gathered at the high position in the circulating water return pipe, the first switch valve is opened in winter, so that one path of water flow in the circulating water upper water pipe passes through the circulating water cooler, the other path of water flow in the circulating water return pipe passes through the branch pipe and then flows into the circulating water return pipe, the branch pipe is not easy to freeze and block in a low-temperature environment, when the high position of the circulating water return pipe needs to be exhausted, the first switch valve is closed, the second switch valve is opened at the same time, so that water in the branch pipe reversely flows out from the second switch valve, the gas gathered at the high position in the circulating water return pipe is exhausted from the second switch valve through the branch pipe under the action of air pressure and water pressure, when the exhaust of the second switch valve is changed from gas into liquid, the gas gathered at the high position in the circulating water return pipe is completely exhausted, the second switch valve is closed, and the first switch valve is opened, avoid the branch pipe to freeze.

Further: the internal diameter of circulating water return pipe is 200mm ~300 mm, the internal diameter of bypass pipe is 20mm ~25 mm, sets up the internal diameter of bypass pipe into the internal diameter that is far less than circulating water return pipe to avoid too much circulating water direct inflow circulating water return pipe and cause the unnecessary energy extravagant.

Further: and a third switch valve is connected in series on the branch pipe close to the connection point of the branch pipe and the circulating water return pipe, and the branch pipe can be maintained when the third switch valve is closed.

The utility model has the beneficial effects that: (1) after the improvement, the circulating water cooler does not need to ascend for high-level exhaust, so that the working efficiency and the safety coefficient are greatly improved;

(2) by optimizing the operation, the antifreezing effect can be achieved in extremely cold weather in winter;

(3) compared with an operation platform, the method has low investment cost and simple implementation.
