Abstract
The utility model relates to a lower sealing head jet flow impingement cooling device of a reaction tower. The lower sealing head jet flow impingement cooling device comprises a water outlet, a cooling jacket, a sealing head, a jacket sealing head and a skirt, wherein the jacket sealing head is positioned at the lower end of the sealing head; the sealing head and the jacket sealing head are hermetically connected to form a cavity; the cooling jacket is arranged on the upper part of the sealing head; the water outlet is formed in the cooling jacket; the skirt is arranged at the lower end of the jacket sealing head. The lower sealing head jet flow impingement cooling device is characterized in that a nozzle which is communicated with the cavity is arranged at the bottom of the jacket sealing head and consists of a water inlet pipe, an elbow and a conical diffusion pipe; the conical diffusion pipe is positioned in the cavity; the water inlet pipe is connected with the conical diffusion pipe through the elbow. According to the lower sealing head jet flow impingement cooling device, a good heat exchange effect is generated in a lower surface area of the sealing head to enable the sealing head to be in a cooling protection range, so that the high-temperature corrosion or material damage of the sealing head is avoided.
Description
Technical field
The utility model relates to a kind of refrigerating unit, especially the lower cover jet impulse refrigerating unit of thermal phosphoric acid reaction tower.
Background technology
In the thermal phosphoric acid reaction tower equipment of by-product industrial steam, liquid phosphor and air generation chemical reaction, discharge a large amount of reaction heat, thereby present high heat load in the bottom of thermal phosphoric acid reaction tower.P due to reaction tower generation
2o
5gas is the industrial chemicals of preparing high-purity phosphoric acid, and reaction tower is manufactured with 316L stainless steel conventionally.And the high heat load of bottom causes lower cover to be in high-temperature zone, temperature can be up to 400 ℃～and 800 ℃, very easily cause the corrosion of phosphoric acid gas to tower body, in order to ensure the metal parts of lower cover, be not subject to the corrosion of phosphoric acid gas, conventionally need to a cooling system be set at lower cover, conventionally adopt jacketed type refrigerating unit.
But the exchange capability of heat of jacketed type refrigerating unit is subject to a great extent in the resistance to heat of lower cover region generation and the impact of hot flow-disturbing, this is that after water coolant heating, the water that temperature is higher is more pressed close to lower cover hot face because the density of water raises and declines with temperature.Under the further effect of the high hot-fluid of lower cover, these high-temperature water are easily vaporized generation steam bubble and are attached to lower cover surface, make to conduct heat and sharply worsen, the hot flow-disturbing that causes water coolant to produce can not effectively approach lower cover surface and play cooling effect, cause on the one hand the corrosion of material, also by destroying rigidity and the intensity of material, when serious, the safety of reaction tower equipment will be jeopardized simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of lower cover jet impulse refrigerating unit of reaction tower, effectively avoids the generation of hot flow-disturbing phenomenon, thereby improves the heat transfer effect on lower cover surface.
For solving the problems of the technologies described above, the lower cover jet impulse refrigerating unit of the reaction tower that the utility model provides comprises water outlet, cooling jacket, end socket, jacket head, skirt, described jacket head is positioned at end socket lower end, end socket and the jacket head formation cavity that is tightly connected, end socket top is provided with cooling jacket, cooling jacket is provided with water outlet, jacket head lower end is provided with skirt, jacket head bottom is provided with the nozzle being communicated with cavity, nozzle is by water inlet pipe, elbow, conic diffuse forms, wherein conic diffuse is arranged in cavity, water inlet pipe is connected with conic diffuse by elbow.
Preferably, the conic diffuse center of described nozzle is over against the central authorities of jacket head.
Preferably, described jacket head is provided with symmetrical posticum.
Preferably, described nozzle quantity is set to more than 1.
The beneficial effects of the utility model are:
Owing to having adopted jet impulse refrigerating unit; water coolant is directly injected to the surface of end socket; middle section at end socket forms impact jet flow; drive and be attached to lower cover steam bubble and high-temperature water around; thereby produce very strong heat transfer effect in end socket lower surface area; make the scope of end socket in cooling protection, to avoid high temperature corrosion or the material of end socket to damage.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the lower cover jet impulse refrigerating unit of reaction tower.
Fig. 2 is the structural representation of the lower cover jet impulse refrigerating unit of reaction tower.
Embodiment
As Fig. 1, shown in Fig. 2, the lower cover jet impulse refrigerating unit of reaction tower comprises water outlet 1, cooling jacket 2, end socket 3, jacket head 4, skirt 5, jacket head 4 is positioned at end socket 3 lower ends, end socket 3 and the jacket head 4 formation cavity that is tightly connected, end socket 3 tops are provided with cooling jacket 2, cooling jacket 2 is provided with water outlet 1, jacket head 4 lower ends are provided with skirt 5, jacket head 4 is provided with symmetrical posticum 10, jacket head 4 bottoms are provided with the nozzle 6 being communicated with cavity, nozzle 6 is by water inlet pipe 7, elbow 8, conic diffuse 9 forms, conic diffuse 9 is arranged in cavity, center is over against the central authorities of jacket head 4, water inlet pipe 7 is connected with conic diffuse 9 by elbow 8.
By adopting such scheme; water coolant sprays with mode of jet by nozzle 6 under certain pressure; be directly injected to the surface of end socket 3; thereby the middle section at end socket 3 forms impact jet flow; drive and be attached to lower cover steam bubble and high-temperature water around; in end socket 3 lower surface area, produce very strong heat transfer effect, make the scope of end socket 3 in cooling protection, to avoid high temperature corrosion or the material of end socket 3 to damage.
Above-mentioned explanation is illustrative rather than restrictive.By above-mentioned explanation those skilled in the art, can recognize that many kinds of the present invention change and distortion, within it also will drop on the spirit and scope of the invention.
