The Composition And Related Introduction Of The Concave Printing Machine Hot Air -Saving Technology

With the influence of various factors such as national policies and social environment, energy -saving and environmentally friendly machinery and equipment have become the direction of major mechanical manufacturers to improve mechanical research and development, and also protect the environment. The concave printing machine is a member of the machinery industry. And its daily work energy consumption is large, so the improvement of energy -saving technology of concave printing machines is also a major strategic direction that major concave printing machine manufacturers are concerned about. Let's talk about the composition and related introduction of the concave printing thermal air -saving technology.

Concave printing machine

At present, thermal air -saving technology applied on the concave printing equipment mainly includes three types: heat pump heating technology, thermal pipe technology, and a fully automatic thermal air circulation system with Lel control.

1. heat pump heating technology. The energy effect of the heat pump is much higher than the electric heating. At present, the heat pump used on the concave printing equipment is generally air energy heat pump. The actual test can save energy by 60%~ 70%

2. Thermal pipe technology. When running the heat pipe technology, the hot air system enters the oven, discharged through the air outlet, and is equipped with a second air return device at the air outlet. Some of them are used to participate in the secondary thermal cycle directly. As a hot air wind, the heat tube heat exchangers are effectively recovered and utilized.

3. A full -automatic hot air circulation system with Lel control. Using a fully automatic thermal air circulation system with LEL control can achieve the following effects: under the premise that the Lel's low explosion limit and the residual solvents do not exceed the standard, the second -time return wind is used to largely. Row 30%~ 50%. The displacement volume decreases accordingly. For future ban, it can be greatly reduced by 30%to 40%of the tail gas treatment investment.
