In the low profit era of Chinese paper packaging industry, entrepreneurs have been turning their attention to internal management, increase business efficiency by saving energy. At present, the paper packaging industry equipment many of them appear old and comes with a variety of issues, in particular energy use seriously inadequate problem is solved and bear the brunt of reform issues. So we must make an effort in the use of energy, use energy-saving equipment for the industry, in order to solve the problem fundamentally.
At the same time, the vacuum hot water boiler also has many advantages, fast boiler as well-known vacuum hot water boiler manufacturers, research and development of production capacity has been an industry leader.
In the design of vacuum hot water boiler, the problem should be noted that the heat medium water vacuum hot water boiler, the negative pressure conditions at the maximum temperature is about 93 deg.] C, the maximum temperature of the boiler water at about 80 ℃, the water temperature and therefore require more when high, the water temperature should be used in other types of high boiler; 2) vacuum hot water boiler heat exchanger tube diameter is small, generally about 10 ~, while not fouling the inner pipe, to prevent impurities clogging the tube system , other sources should be installed or filter before the boiler return pipe inlet; 3) vacuum hot water boiler design, according to the system pressure, the pressure parameter determining unit, to ensure that the working pressure of the pressure unit to meet the system requirements. Pressure relief valve is provided at the interface of the vacuum hot water boiler system should be designed in which the unit set pressure must be less than the maximum allowable pressure, the pressure relief valve unit and the valve shall be fitted to the connecting portion based on such a design configuration of the vacuum hot water boiler , as compared with the vacuum hot water boiler pressure hot water boiler, has its own unique advantages, table 1 Comparative characteristic of both systems were schemes.
The comparison of boiler failure rate: 1, vacuum degree of vacuum boiler in vacuum boiler * important index of stable operation of furnace, and four main factors that often affect vacuum degree: 1) whether there is leakage point in boiler body and valve, instrument, and so on. At present, including imported valves and meters can not ensure that there is no leakage within 3 years. 2) it is inevitable that failure of control part, boiler controller and negative pressure, pressure controller will also happen in operation, for example, the failure rate of domestic controller is even higher. 3) vacuum pump, three-way solenoid valve is working normally or not. As a result of the vacuum pump, the three-way solenoid valve is not operating very often and is originally installed Mouth also easy to appear the card dead and in the operation occurs the fault. 4) the load can not change abruptly, the boiler load change is very normal for the boiler, generally, the boiler can meet the load regulation of 30% ~ 100%. The above faults will cause the change of the vacuum degree of the boiler. At this time, the gas tightness of the boiler, whether the control part is normal or not, the vacuum pump, the three-way solenoid valve are normal or not, and the change of load should be checked. If all normal should be checked negative pressure and pressure controller settings, all normal vacuum recovery boiler can still be normal, otherwise the boiler should be shut down and overhauled all-round inspection. The failure maintenance rate of vacuum boiler in actual operation is higher than that of existing boiler. Pressure steam boiler, control requirements are higher than steam boiler. 2. The normal pressure boiler only has the basic time, temperature, water level control, hot water boiler controller selected the original inlet, the failure rate is relatively low. There is no need to maintain vacuum control equipment, without complex control equipment, personnel operation requirements are simpler than vacuum boilers, the probability of downtime maintenance is less, the actual operation of hot water boiler is much more stable. The comparison of boiler safety: 1. If the vacuum degree of the vacuum boiler is not guaranteed due to the above four factors, it may cause the boiler pressure to rise rapidly, and the boiler body is a closed structure, and the operator may cause the boiler pressure to rise rapidly. If paralyzed, it is possible to become the danger of pressured steam boiler, the vacuum operation of vacuum boiler is more safe based on the premise that the vacuum degree of boiler can not appear problem. 2. The atmospheric hot water boiler of atmospheric pressure boiler is as simple as boiling water, and no fault will cause boiler pressure. The boiler www.boilermanufactory.com is more safe and reliable, and it is really free of any danger.
