1.0.1

This standard is developed in order to regulate the design of mechanical mixing equipment (hereinafter referred to as mixing equipment), improve the design level, and achieve advanced technology, economic rationality, safety and applicability, and ensure quality.

1.0.2

This standard specifies the requirements for design, manufacture, inspection and acceptance of mixing equipment.

1.0.3

This standard is applicable to mixing equipment in chemical and petrochemical plants and other similar devices.

1.0.4

This standard is not applicable to the following mixing equipment:

1 Mixing equipment heated directly by flame;

2 Mixing equipment with neutron radiation damage failure risk in nuclear-energy plant;

3 Mobile mixing equipment (such as those carried by vehicle or ship);

4 Mixing equipment needing to be subjected to fatigue analysis.

1.0.5

In addition to this standard, the design of mixing equipment shall also meet those stipulated in the current relevant standards of the nation.

2.0.1 mixing equipment

equipment consisting of two major parts, namely mixing vessel and agitator

2.0.2 mixing vessels

vessel that, together with agitator, completes the physical and chemical processes (such as suspension, dispersion, emulsification, mixing, dissolution, absorption, extraction, chemical reaction and heat transfer) of the medium during operation

2.0.3 agitators

machine consisting of impeller, shaft, shaft seal system and transmission device (driving machine, reducer, frame and coupling)

2.0.4 impellers

component consisting of blades or vane wheel of various geometric shapes

2.0.5 shaft seals

sealing device at the joint of agitator transmission shaft and mixing vessel

3.0.1

The combination type of mixing vessel and agitator shall meet the requirements of mixing equipment size, installation space, arrangement of vessel process nozzle and control of flow field movement direction. See Table 3.0.1 for typical combination types.
