[0002] With the development of the market economy, many new carton factories have been added. In order to obtain the development of the enterprise, the only way to obtain benefits is to expand the scale of survival. Due to the large scale of the production line, high degree of automation, and high production speed of 300M / min, there is a demand for steam consumption. In order to meet the high-speed and high-efficiency characteristics of the production line, and to achieve high heat exchange speed, in order to meet the needs of the above work, it is necessary to increase the gas consumption of the production line to meet the process temperature of the corrugated board and increase the steam discharge. Some production processes can no longer meet the needs of production

Embodiment Construction
[0008] This technical solution is to utilize the indirect heating process of steam. As the steam releases the latent heat of vaporization in the steam-using equipment, a large amount of high-temperature saturated condensed water is produced. About 30% of the enthalpy value has high utilization value, and it is carried out by using a flash tank to generate flash steam and low-temperature condensed water. Flash steam can be used as secondary steam to supplement low-pressure steam equipment. The condensed water is directly pumped to the boiler body by the condensed water recovery device, so as to increase the boiler make-up water temperature and balance the boiler pressure. Not only can save boiler fuel and demineralized water, but also can greatly reduce the operating cost of the boiler. Specific examples figure 1 As shown, the output end of the single-chip microcomputer 6 is bidirectionally connected to the HIM man-machine interface 5, and the output end of the single-chip mi...

The invention discloses a constant-temperature constant-pressure intelligent control system for steam of a corrugated board. The output end of a single-chip microcomputer is in double-way connection with an HIM man-machine interface, and the output end of the single-chip microcomputer is in double-way connection with the input end of an actuator. The input end of the single-chip microcomputer is connected with an analog-digital converter, and the input end of the analog-digital converter is connected with the output end of a pressure sensor, the output end of a temperature sensor and the output end of a liquid level sensor. The actuator comprises a primary heating valve, a secondary pressure increasing valve, a condensate water valve and an electric actuator body. According to the technical scheme, the steam use rate can be saved by 18% to 25% compared with a traditional steam conveying mode, and can be higher, the adhesive strength and flatness of the corrugated board are effectively improved, gelatinization of glue reaches an optimal state, and the phenomenon that the use amount of the glue is too large due to the fact that the temperature is not ideal can be reduced.
