Air Preheaters (APH)
An air preheater (APH) is a device used to heat air, commonly used in industrial boilers, thermal power plants, and other thermal energy facilities. APH improves the thermal efficiency of the boiler by transferring heat from the flue gas to the air entering the boiler through heat exchange with it.
APH usually consists of a Heat Exchanger with a number of parallel pipes inside the exchanger through which smoke and air flow to allow heat exchange. In APH, the smoke flows on the outside of the heat exchanger and the air flows on the inside so that the heat between the smoke and the air can be transferred through the pipe walls.
The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects. At present, our customers have covered all large and medium-sized petrochemical enterprises in China and established long-term strategic cooperative partnership with them. Products are exported to Southeast Asia, Middle East, and other regions.

Over the years, people have come up with countless methods in their confrontation with formaldehyde. What are their advantages and disadvantages? Who is the most effective way to eliminate formaldehyde?
Ventilation method, plant adsorption method
Advantages: Ventilation is known as the cheapest way to remove formaldehyde. It does not require any cost, as long as you pay attention to the habit of creating windows for ventilation and convection indoor and outdoor air. The method of plant adsorption is the use of the adsorption of harmful substances in the air during the photosynthesis process of green vegetation to absorb part of the formaldehyde. It is green and environmentally friendly, and at the same time, it brings people aesthetic enjoyment.
Disadvantages: Ventilation method is greatly affected by the climate conditions, plant absorption adsorption effect is limited, while careful selection of vegetation to avoid respiratory infections and other side effects. It is not the most effective method of removing formaldehyde, but it can be used as an auxiliary method to lay a solid foundation for healthy air.
Chemical removal method
Advantages: The use of chemical agents to quickly remove formaldehyde, or use some fresh air spray to mask the pungent odor of formaldehyde, this method is effective, really achieve the effect of rapid removal of formaldehyde, and the operation is not complicated, to meet a lot of rush to new homes Or need to solve the consumer demand for pungent odors in the home.
Disadvantages: These sprays themselves are chemical substances. The decomposition of formaldehyde, apart from its toxicity, will cause secondary pollution of the residue to the air. It is obviously not our pursuit to dismantle the Western Wall to fill the Western Wall. At the same time, the period of volatilization of formaldehyde is 3 to 15 years. The method of removing formaldehyde that is tried once and for all is obviously a cup of water. If it is used repeatedly, it will not only pollute the air, but also increase the cost of treatment.
Activated carbon adsorption
Advantages: Activated carbon adsorption method is better than plant absorption method, it has better adsorption effect, and it is environmentally friendly, it will not cause secondary pollution, and it can be removed 24 hours a day, which can protect the air health of the room all-weather.
Disadvantages: The cost is high, and the activated carbon needs to be exposed to the sun for some time after use, or it needs to be replaced and it is not easy to control and operate.
Anion Degradation
Advantages: The role of negative ions in the degradation of formaldehyde has been proven by a large number of clinical trials, and it has thus become a rare weapon for people to fight decoration pollution. As an indispensable and important component of the natural air, the anion itself is colorless and odorless. It rapidly degrades formaldehyde and does not cause any form of secondary pollution. Therefore, the negative ion to explain herbal Dialyte is considered to be the most recent addition to formaldehyde. effective method.
Disadvantages: The choice must be made carefully. If the resulting negative ion has a large particle size, its biological activity is low, and the effect of formaldehyde deposition is naturally reduced. Therefore, how to choose becomes a problem for many people. In fact, the key is to look for core technologies. Do not blindly congregate. Choose only celebrities and prices.
What is the most effective method of removing formaldehyde? Using the above methods in a comprehensive manner and avoiding weaknesses, this is the most reasonable way to create an ecological living room.
In addition to formaldehyde, decoration is imperative, "prescription for remedy" is the key
The new house has a pungent odor. Why is there an old house? Cold cough fever old but can not find the reasons? With the improvement of people's taste for decoration, a large number of man-made boards have begun to cater for people's pleasing desires. However, decoration pollution such as formaldehyde has become the biggest problem. Unpleasant odors, strange diseases continue to decorate, in addition to formaldehyde has become a mandatory course for everyone, in addition to formaldehyde is imperative to "prescribe the right medicine" is the key.
