Friends who have cars have probably had such a mental journey: finally ruthlessly bought a car, and since then, you have one more child. You want your child to grow up, you have to feed it, you want the car to walk, you have to fuel it. The child is sick, you have to spend money on treatment, the car is broken, you have to repair it.
I hope that the child can spend less money, not get sick, and be excellent.
I hope that the car can add less fuel, no trouble, and good quality.
There are some things we can't do about it, but there are some things we've been looking for.
New energy vehicles came into being~
In recent years, the rapid development of new energy vehicles shows that consumers attach great importance to the cost of parenting after purchase.
In the enterprise development strategy, cost control is in an extremely important position. In production-oriented enterprises, energy saving of equipment is the top priority to reduce costs.
In the field of our dehumidification dryers, two of them are more common in the market.
One is molecular sieve dehumidification dryer, and the other is honeycomb rotary dehumidification dryer
The imported brands that are used more in China are dryers that use molecular sieve switching.
The key to the double barrel molecular sieve dehumidifier is: A and B two molecular sieve barrels switch use.
When barrel A is absorbing moisture, barrel B is regenerative heating, and when barrel B completes regeneration, the regeneration fan and regenerative heating stop running and start waiting.
When the A barrel molecular sieve is saturated with moisture, switch to the B barrel, at this time, the B barrel begins to absorb water, A barrel begins to regenerate heating, when the regeneration is completed, the regeneration fan and regenerative heating stop running and start waiting.
The key to the honeycomb dehumidifier is: the honeycomb dehumidifier wheel keeps turning slowly.
This runner is divided into three zones: dehumidification zone, regeneration zone, cooling zone.
In the process of continuous rotation of the runner, dehumidification, regeneration, cooling are carried out at the same time, since there is no time to wait for switching, the fan, regenerative heating always keeps running.
The following figure is a diagram of molecular sieve regeneration heating and rotary wheel regeneration heating:
In this chart:
The molecular sieve dryer is regenerated and heated every 4 hours (Jinyue dew point switching mode, in the case of low initial moisture content of raw materials, it can be switched once in 8-12 hours).
The rotary dryer is regenerated and heated every 4 minutes, and about 60 regenerative heating processes are required in 4 hours.
Through multiple analysis of experimental results:
To dry different kinds of raw materials, molecular sieve dryers save 18% to 65% in energy consumption compared with rotary dryers.
Conventional treatment of 1 ton of PE breathable material, double drum molecular sieve dehumidifier saves 15 degrees of electricity than the rotary dehumidifier, if the daily production capacity is 24 tons, 8760 tons a year, that can save 131400 yuan per year. It can save more than one million in ten years!
If it is those enterprises with large production capacity, it saves millions and tens of millions every year. In a future article, Jinyue will show you a case study of how we help companies save millions of dollars in electricity bills every year.
Seeing this, many people know that the dryer of molecular sieve switching mode has low energy consumption, however:
The dryer of molecular sieve switching mode is also divided into time switching and dew point switching
The principle of the traditional time switching mode is that the regeneration completion time is set at 4 hours, and the regeneration fan continues to operate. Regardless of the moisture of the raw materials, and whether the regeneration is completed or not, it can only be switched once in 4 hours, although compared with the rotary dehumidifier, the twin-barrel molecular sieve time switching mode has been more energy-saving in terms of energy consumption, but compared with the dew point switching double-cylinder molecular sieve dehumidifier, in terms of energy consumption, it is a large distance.
The principle of dew point switching mode: according to different raw materials, set different dew point values, when the dew point value drops to the set value to start switching molecular sieve, if the moisture content of raw materials is small, dew point drops slowly, then the molecular sieve switching time will become longer, if the switching time is 8 hours, if the molecular sieve regeneration completion time of A barrel is 3 hours, then there is 5 hours of waiting time, at this time both the regeneration fan and the regeneration heating are no longer running.
