2014 Chengdu Water Show (CDWF2014) Organizing Committee News: Chengdu Surface Engineering Industry Association will once again organize its member units to visit the "2014 10th China Chengdu International Conference" held on March 13-15, 2014 at the New International Convention & Exposition Center in Chengdu Century City. Water Supply and Drainage Water Treatment Technology and Equipment Exhibition (CDWF 2014)". The surface engineering industry as an industry with large sewage discharge capacity, the demand for water treatment equipment can not be overlooked. In recent years, the state’s efforts to strengthen the environmental protection industry have increased, various kinds of sewage treatment and conditioning have been introduced and emission standards have gradually increased. Under this background, the surface engineering industry will continue to require equipment and technology in the process of sewage disposal. improve. The Chengdu Surface Engineering Industry Association has an important position in the western industrial region. Its member companies include well-known enterprises in the fields of machinery, electronics, light industry, chemical industry, municipal engineering, building materials, and metallurgy. The Chengdu Water Show (CDWF) has been successfully held for nine times, and its professional level has been recognized by the industry's authoritative organizations. The Chengdu Surface Engineering Industry Association and the Chengdu Water Exhibition Organizing Committee have established long-term cooperative relations. The strong support and in-depth participation of the Chengdu Surface Engineering Industry Association will greatly increase the quality of the audience. By then, Chengdu Water Treatment (CDWF2014) will perform a grand event of equipment and technology with authorities and well-known enterprises in the western water treatment industry.

1. Water supply equipment
It is composed of water treatment equipment, water supply tank and feed pump 24. Water treatment equipment is used to remove impurities in water, such as oxygen, calcium and magnesium ions, to avoid scaling and corrosion on the inner wall of steam boiler, and to ensure the quality of boiler water supply. The treated boiler feed water is lifted by the feed water pump and then sent to the upper drum through the economizer.
2. Ventilation
The ventilation equipment includes air supply fan, induced draft fan and chimney. Its function is to provide air for mule fuel combustion and lead out combustion product flue gas from the boiler, so as to ensure the normal combustion, and make the flue gas wash the heating surface at the necessary flow rate of 7a68696466fe78988e69d8331333433626465 to strengthen heat transfer. Finally, the stack with a certain height will exhaust the smoke to the atmosphere to reduce the smoke pollution and improve environmental health.
3. Fuel supply, slag removal and dust removal equipment
This is for conveying fuel to boiler, removing ash and purifying flue gas. Belt conveyor, ash conveyor, ash truck and dust remover, etc. For boilers that need to be pre processed with fuel, fuel preparation such as screening, crushing and coal grinding shall also be included. In addition, the dust remover or flue gas desulfurization and denitrification device installed in the flue at the tail of the boiler is an indispensable auxiliary equipment to reduce the smoke pollution and protect the environment.
4. Check instruments and automatic control equipment
In addition to water level gauge, pressure gauge, safety valve and other instruments installed on the boiler body, in order to supervise, regulate and control the safe and economic normal operation of the boiler equipment, a series of instruments, automatic boiler feed water regulating device, automatic fuel combustion control device, etc. are often installed. Some boiler rooms are also equipped with industrial television and remote control device and even more modern automatic control system, more Scientific supervision. Control boiler operation.
Boiler auxiliary equipment, not every boiler is equipped completely, but with the boiler capacity, type, fuel characteristics and combustion mode as well as water quality characteristics and many other factors to adapt to local conditions, adapt to the times, more practical requirements and objective conditions.
