With the continuous development of science and technology, Combination dryer is increasingly widely used in daily life. In the structure of the combination dryer, each component plays a very important role. A silencer is a device that reduces aerodynamic noise in the airflow channel. Do you know what harm will be caused if it fails? Next, the ultrafiltration industry will explain to you, hoping to help you.

The role of the silencer in the combination dryer:

The main function of the silencer in the combination dryer is to reduce the noise generated when the regenerated gas is discharged from the combination dryer. Because the regenerated gas has a certain pressure during the discharge process, and the exhaust speed is fast, it will cause gas vibration and generate strong exhaust noise, generally reaching 80~110dB. According to relevant regulations, when the exhaust noise is greater than 75db, noise reduction measures need to be taken.

In the combination dryer, due to the large amount of dust and moisture in the regenerated exhaust gas, condensate will accumulate easily when the temperature is suitable, which is easy to block the silencer of the combination dryer. Therefore, the working conditions of the combination dryer silencer are very harsh, and it is a consumable part in the combination dryer.

Once the silencer fails, it will cause trouble to the normal operation of the dryer. The silencer passes through regenerated waste gas with high water content. As long as the temperature conditions are met, it is easy to "condense" in the silencer. Worse still, a large amount of dust impurities detached from the adsorbent are mixed in the regenerated waste gas, and these impurities are easy to condense together and adhere to the exhaust channel of the silencer, blocking the silencer. Once the silencer is blocked, the regenerated waste gas will lose the discharge channel, causing the internal pressure of the regeneration tower to continue to rise, and the regeneration operation cannot be carried out. In severe cases, the silencer will rupture.

What are the consumable parts of the combination dryer

In industry, adsorbent, controller, valve and silencer are collectively known as the four major consumable parts of the combination dryer.

As the industrial main body of the dryer, the adsorbent is often affected by pressure, water vapor and heat in most cases. It is easily mechanically damaged and contaminated by the medium, thus reducing the performance of the adsorbent.

The controller is the command of the combination dryer. With the development of auxiliary electronic technology and the wide application of PLC technology, a qualitative leap has been made in control accuracy and reliability compared with the early electromechanical control. In addition to further improving the anti-interference and overload capacity of the heating regeneration components, other control components are no longer consumable parts.

The control valve is an easily damaged part of the combination dryer. Frequent switching and long-term mixed water intrusion and adsorbent shedding are important reasons for valve damage.

When purchasing Combination dryer its quality can be judged by the following points:

1. According to national standards, after the adsorption tower is cooled, a separate inspection report issued by the state is required before it can be installed at the user's location.

2. Control system, for non-heat dryers less than 100m/Min, and micro-heat dryers less than 40m/Min, there is no problem in choosing a PC control system. If it is higher than this value, a PLC control system should be considered. Other models should be PLC control systems.

3. Heater, a good heater generally has a baffle structure, the heating tube is a stainless steel tube, and overtemperature protection is required. This is not easy to distinguish. If an appearance inspection is carried out, it depends on the process.
