Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, a diazotization reation kettle's cooling structure, including reation kettle jar body 4 and control module, still include: a grid-shaped cooling structure and a cooling agent supply device.
The grid-shaped cooling structure is arranged on the inner wall of the reaction kettle tank body 4 and is detachably connected with the reaction kettle tank body 4. The cooling agent supply device is communicated with the grid-shaped cooling structure, is electrically connected with the control module and is used for supplying the cooling agent to the grid-shaped cooling structure.
Wherein the grid cooling structure includes: a cooling agent inlet pipe 3, a cooling agent outlet pipe 2 and a cooling pipe 1 group. The temperature reducing agent inlet pipe 3 is circumferentially arranged on the inner wall of the reaction kettle tank body 4, and one end of the temperature reducing agent inlet pipe is communicated with the temperature reducing agent supply device. The cooling agent outlet pipe 2 is arranged on the inner wall of the reaction kettle tank body 4 along the circumferential direction, and one end of the cooling agent outlet pipe is communicated with the cooling agent supply device. The cooling agent outlet pipe 2 is higher than the cooling agent inlet pipe 3. The cooling pipe 1 group is composed of a plurality of cooling pipes 1 which are arranged in parallel. One end of the cooling pipe 1 is communicated with a cooling agent inlet pipe 3, and the other end is communicated with a cooling agent outlet pipe 2. The grid-shaped cooling structure and the cooling agent supply device are filled with cooling agent, and the cooling agent is ethylene glycol.
As shown in fig. 2, the coolant supply device includes a low-temperature coolant outlet 7 and a high-temperature coolant inlet 6, and a coolant cooling block 5. The low-temperature cooling agent outlet 7 is communicated with the cooling agent inlet pipe 3. The high-temperature coolant inlet 6 is communicated with the coolant outlet pipe 2. The coolant cooling block 5 is used for cooling the coolant.
This application adopts bars shape cooling structure for under the area of contact's with the reation kettle inner wall the condition not reduced, shortened the stroke of cooling agent in reation kettle, make the cooling agent all can exert the biggest cooling effect in every cooling tube 1, and then reduced the energy resource consumption who produces in order to promote the circulation speed.
And in this application, the higher than coolant that will cool down the setting of coolant exit tube 2 advances pipe 3, because the density of the coolant under the different temperature condition is different, the density of coolant diminishes along with the rise of coolant temperature, thereby the higher coolant of temperature has the trend to the motion of coolant top layer, so the lower than coolant exit tube 2 that will cool down the setting of coolant entry tube 3 in this application, thereby make the flow direction of coolant be from bottom to top, compare in the mode of flow direction top-down of coolant, the flow mode from bottom to top of coolant has reduced the automatic energy that upwards moves of coolant of overcoming higher temperature, and utilized the energy of coolant automatic movement, the required energy reduction of coolant flow, further reduction energy resource consumption. Meanwhile, the cooling effect is better.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
