Embodiment 1

[0030] Such as figure 1 with figure 2 As shown, the steam mixer includes a heater housing 11, the top of one end of the heater housing 11 is connected to the main steam pipe 6 through a flow regulating valve, and the other end of the heater housing 11 is connected to the mixed steam pipe through a gate valve or a shut-off valve. 1 connection, the main steam pipe 6 is connected to the mixed steam pipe 1 through a gate valve or a shut-off valve, and the bottom of the heater housing 11 opposite to the entrance of the main steam pipe 6 is connected to the heating steam pipe 9 through a flow regulating valve, and the main steam pipe 6 is directed to Extending inside the heater housing 11 are a connection pipe 15 and a main steam distribution pipe 5 arranged in sequence. The main steam distribution pipe 5 is evenly distributed along the axial direction of the heater housing 11, and the air flow is parallel to the radial direction of the heater housing 11. The heating steam pipe 9 ...

Embodiment 2

[0033] On the basis of Example 1, different from Example 1, such as image 3As shown in the steam mixer, the main steam distribution pipe 5 is horizontally arranged as a cylindrical pipe along the central axis of the heater shell, the end of the main steam distribution pipe 5 is sealed by a blocking plate a12, and the bottom of the main steam distribution pipe 5 is opened There are circular steam holes 13, and there are elongated steam holes 14 equally spaced between adjacent circular steam holes 13. The elongated steam holes 14 are distributed from the bottom of the main steam distribution pipe 5 to the main steam distribution pipe. The central axis of the piping 5 is recessed and extended.

[0034] Open the circular steam hole 13 when the steam volume is relatively small, the diameter of the circular steam hole 13 is not more than 15mm, and open the strip steam hole 14 when the steam volume is relatively large, the width a of the strip steam hole 14 is Not greater than 10mm...

Embodiment 3

[0036] On the basis of Example 1, different from Example 1, such as Figure 4 , Figure 5 , Image 6 , Figure 7 with Figure 8 As shown in the steam mixer, the combined nozzle includes a spiral nozzle 16, a central nozzle 17 and a sleeve 19, and the central nozzle 17 is sleeved inside the spiral nozzle 16 along the central axis of the spiral nozzle 16, and the central nozzle 17 and the spiral nozzle 16 The bottom of the nozzle is sealed by the blocking plate b18, and the sleeve 19 is sleeved on the outside of the spiral nozzle 16.

[0037] The casing 19 is provided with a hollow cylindrical cavity, and the upper and lower ends of the hollow cylindrical cavity are all set as retracted ports. The internal thread provided on the inner wall of the upper port of the casing 19 and the external thread on the outer wall of the spiral nozzle 16 are assembled and matched. A protruding U-shaped clamp is provided on the outer wall, and the U-shaped clamp engages with the upper end su...

Abstract

The invention discloses a steam mixer. The top of one end of the heater shell is connected to the main steam pipe through a flow regulating valve, the other end of the heater shell is connected to the mixed steam pipe through a gate valve or a cut-off valve, and the main steam pipe is passed through a gate valve or a cut-off valve. The valve is connected to the mixed steam pipe, and the bottom of the heater housing opposite to the inlet of the main steam pipe is connected to the heating steam pipe through a flow regulating valve. The steam distribution pipes are evenly distributed along the axial direction of the heater shell, and the heating steam pipes are extended into the heater shell with combined nozzles. Mix a large flow of saturated steam and a superheated steam in the equipment to form a slightly superheated steam with a certain degree of superheat; it has high heat exchange efficiency and can effectively reduce the generation of steam when the pipe network transports The impact of water hammer is powerful for the safe operation of the pipe network.

Description

technical field [0001] The invention belongs to the technical field of mixer equipment, in particular to a steam mixer. Background technique [0002] In industrial production, especially in waste heat utilization devices, the steam generated by waste heat boilers or steam regenerators is saturated steam, and what users need is slightly superheated steam with a certain degree of superheat, which requires another heat source to heat The saturated steam is generally heated by another high-quality superheated steam in industry. The method is roughly divided into partition wall heat exchange and steam injection. The method of time heat transfer between partition walls is generally suitable for large temperature differences. The high-quality steam after heat exchange still has downstream users. If the high-quality steam after heat exchange cannot be found If it is used properly, the superheated steam after heat exchange still has a lot of energy, which will be a huge waste of ene...
