Description

Technical Field

[0001] The utility model relates to the field of steam curing of pipe segments, in particular to a low-pressure and high-efficiency steam curing device for steam curing of pipe segments. Background Art

[0002] Currently, steam generation equipment relies on traditional boilers. These boilers require continuous operation, maintaining temperature even when steam is not needed. This results in high energy consumption, significant floor space, and low safety performance. To facilitate ease of use and eliminate the need for inspection, smaller steam generators have emerged on the market. However, these generators offer low temperatures, limited steam output, and limited energy savings, making them unsuitable for applications requiring large amounts of steam, such as concrete curing.

[0003] Since traditional boilers need to heat a large amount of water first and maintain the temperature, they need to be kept warm even when steam is not needed, which will cause a lot of energy waste. The design of the combustion chamber structure and the steam output structure will greatly reduce the energy transfer efficiency, resulting in a waste of resources. It is also impossible to produce steam efficiently in a short time and the preparation time is long.

[0004] Prior art 202121854010.3 discloses an automated low-pressure steam generator for concrete component maintenance.

The problem is then solved, and the ignition module 53 is started to ignite the gas-air mixture in the main combustion chamber to generate a stable main flame. Water is then injected into the water tank between the inner wall of the cylinder body 1 and the inner tank 2 through the water inlet pipe 4. The water level in the water tank then slowly rises. During the rising process, the main flame preheats the water in the water tank. When the water level reaches the limit height of the inner tank 2, the water overflows along the inner wall of the inner tank 2. The main flame then quickly heats the moisture on the inner wall of the inner tank 2, and the water is quickly evaporated to form high-temperature steam. The steam is then discharged from the steam exhaust pipe 6 at the bottom of the cylinder body 1 into the curing room under the action of an external fan.
