Problems solved by technology

However, as the fluid velocity in the jacket increases, the secondary flow generated by the heat exchange fluid in the spiral jacket contributes less to the heat transfer enhancement, and the heat transfer enhancement effect is less significant, while the flow resistance increases significantly.

Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] refer to Figure 1-4 , the invention provides a heat transfer jacket of a reactor with an ejector, which is installed on the outside of the reactor, and a cooling liquid circulation channel in contact with the reactor body is provided in the jacket, and at least A jet device 3 is welded on the outer wall of the jacket, and its jet direction is at an angle α to the main flow tangential direction of the cooling liquid in the jacket, and α is selected as 30-60 degrees.

[0017] When α is greater than 60 degrees, the impact of the jet fluid on the inner wall of the jacket is more severe, which will cause a large loss of...

Abstract

The invention relates to a reaction device applied to the fields of pharmacy and fine chemical engineering, in particular to a reaction kettle heat transfer jacket with an ejector. The ejector is installed on the outer side wall face of a traditional outer jacket, the flow field structure in the jacket is improved through the impact and induction effect of jet flow, and heat exchange strengthening is achieved. The reaction kettle heat transfer jacket is high in heat transfer efficiency, convenient to implement and control, capable of obtaining a high enhanced heat transfer effect with small flow resistance loss and capable of being used for transferring reaction waste heat of reaction kettles in the fine chemical engineering fields of pharmacy, printing and dyeing and the like.

Description

technical field [0001] The invention relates to a reaction device applied in the fields of pharmacy and fine chemical industry, in particular to a heat transfer jacket of a reactor with a jet. Background technique [0002] Reactors used in fine chemical industries such as pharmaceuticals and printing and dyeing often need to install heat transfer jackets to remove the residual heat of reaction in the reactor. The removal of reaction heat is an important factor restricting the size of the reactor. At present, the commonly used types of external jackets for reactors include integral jackets, integral jackets with spiral deflectors, spiral half-pipe jackets, steel jackets, etc., among which spiral half-pipe jackets and integral jackets with spiral deflectors The heat transfer effect of the sleeve is good, mainly because its structure is similar to a curved heat transfer channel, and when the cooling fluid flows in it, a secondary flow can be generated due to the centrifugal for...
