Recently, the "safe access conditions for the caustic soda industry (draft for comment)" was completed at the end of last year. Recently, the deputy director of the State Administration of Work Safety proposed to speed up the revision and improvement of the "chlorine-alkali industry safety access standards", strict access to high-risk chemical industries such as chlor-alkali. The automatic monitoring of exhaust gas was also drafted into the "Entry Conditions" to improve safety. It will also bring new business opportunities and huge development space for the automatic monitoring equipment industry.

In high-risk chemical industry, special emphasis should be placed on safety, and improving safety access conditions for high-risk chemical industry is a necessary measure to ensure safety, and it is also an important means of regulating the development of the industry. The conditions for safe access to the caustic soda industry (Draft for Soliciting Opinions) were completed at the end of last year. Recently, the deputy director of the State Administration of Work Safety proposed to speed up the revision and improvement of the "chlorine-alkali industry safety access standards", strict access to high-risk chemical industries such as chlor-alkali.

It is reported that the "access conditions" involve the layout of production enterprises, production equipment and process requirements and safety facilities, storage and transportation requirements, safety standardization requirements, and responsibilities, supervision and management. The "Admission Requirements" is expected to be announced in the second half of the year and will be mandatory after the announcement.

With the soon-to-be-released "Access Conditions", more than 200 chlor-alkali industry enterprises in China will be involved. In recent years, more and more chlorine accidents have occurred because of the lack of on-line monitoring equipment. Therefore, the requirements for automatic monitoring of exhaust gas have also been drafted into the “entry conditions” to improve safety. According to the "access conditions" involved in the "electrolysis, ** dry compression device, ** storage tanks, cylinder filling, accidental chlorine devices and other direct response emissions ** exhaust gas treatment equipment must be equipped with harmful gas monitoring probes and other automatic leak monitoring Requirements for facilities, etc., and the installation and renovation of related equipment of some enterprises have begun. This will also bring new business opportunities and huge room for development for the automatic monitoring equipment industry.

what is the Pipe Fan?

Pipe fan selection control parameters for the air volume, total pressure, efficiency, noise, motor power and so on. Depending on the physical and chemical properties of the gas being transported, fans of different uses are selected.

Features

1. Pipe fan selection control parameters for the air volume, total pressure, efficiency, noise, motor power and so on.

2. According to the physical and chemical properties of the gas being transported, select the fan for different purposes. Such as the delivery of clean air, should choose a general fan; transport flammable and explosive gases, explosion-proof fan should be selected; corrosive gas transmission, corrosion-resistant fan should be used.

3. Ventilator selection, should consider the leakage of piping system losses, calculation errors, and the actual fan fan, the negative pressure deviation, the general use of air flow 1.05 ~ 1.1, wind pressure of 1.10 to 1.15 safety factor. However, it is neither too large nor too large to prevent the fan from operating in an area of low efficiency for a long time.

4. Pay attention to the matching characteristics of the pipe network resistance characteristics and fan characteristics. In order for the ventilator to operate stably, the ventilator should be operated near its maximum efficiency point. The operating point of the ventilator is located on the right side of the full pressure peak point in the performance curve (ie, on the gales side and generally at 80% of the full pressure peak) ).

5. For ventilation systems with muffler requirements, fans with high efficiency and low impeller circumferential speed should be selected first and operate near the highest efficiency point. Should also be based on the ventilation system noise and vibration propagation, take the appropriate noise reduction and damping measures.

6. Pipe fan is through the blade shape changes, the air flow into the fan, the existing part of the axial flow, but also produce part of the centrifugal effect, so its performance is between the axial flow fan and Centrifugal Fan.

7. Piping ventilator can provide medium pressure and moderate air flow, ventilation system used in high-rise civil buildings are more appropriate.

Installation points

1) The natural frequency of the basic device shall not be greater than 1/3 of the motor and fan speed;

2) The difference between the vibration speed when the ventilator is running and the vibration speed when the ventilator is stationary should be more than 3 times.

2. Ventilator inlet and outlet connections between the duct should be set flexible joints. Into the air duct, air duct and other devices should be a separate support, and by the foundation or other components of the firm support firm, the chassis should not bear the weight of other parts.

3. Fan installed in the building components, should take measures to isolate vibration.

4. Fan installation can refer to the following national building standard design atlas.

5. Pipe fan can be installed in the straight pipe, with easy to take over, taking up the advantages of smaller space.
