Description

Technical Field

[0001] The utility model relates to the technical field of pure steam sampling, in particular to a pure steam rapid sampling device. Background Art

[0002] Pure steam is usually produced by heating purified water or water for injection with industrial steam. It is an indispensable production condition in the biopharmaceutical industry. Almost all heating, concentration, drying and heat exchange in pharmaceutical production require pure steam. In some cases, the pure steam sampling device includes a sampling tube and a condensation mechanism. When sampling, pure steam is passed into the sampling tube. The pure steam in the sampling tube is converted into condensed water by the condensation action of the condensation mechanism, and the condensed water flows out of the sampling tube to complete the collection.

[0003] 1. The existing pure steam sampling device uses a condenser to cool the steam and then take samples. Since the length and size of the inner tube of the condenser are fixed, the time the steam stays in the tube is fixed. If the steam is sufficient, part of the steam will directly flow out of the condenser and will not condense in the condenser, resulting in low efficiency of pure steam sampling.

[0004] 2. The existing condenser tube has a certain contact area with the cooling water, which results in poor heat exchange between the cooling water and the inner tube of the condenser tube, affecting the condensation effect of the steam. Utility Model Content

[0005] The utility model aims to provide a pure steam rapid sampling device, which solves the above-mentioned problems in the prior art.

[0006] To achieve the above object, the utility model provides the following technical solution: a pure steam rapid sampling device, comprising a cylindrical outer tube, an inner tube fixed inside the outer tube, an upper water outlet opened at the upper end of the outer tube, a lower water outlet opened at the lower end of the outer tube, and a water inlet opened on the outer wall of the outer tube near the upper water outlet;

[0007] The inner tube includes a plurality of conical tubes connected in series, an air inlet is provided at the upper end of the inner tube, a sampling port is provided at the lower end of the inner tube, heat dissipation rings are fixed to the outer walls of the plurality of conical tubes, separation tubes are provided inside the conical tubes, a flow guide cavity is formed between the separation tubes and the inner tube, guide tubes are provided inside the connection points of the plurality of conical tubes, a water guide ring is formed between the guide tubes and the inner tube.

[0008] Preferably, the separation cylinder is conical, and a plurality of connecting blocks are fixed along the circumference of the outer wall of the separation cylinder. The separation cylinder is fixedly connected to the inner tube via the connecting blocks. The diameter of the upper end of the separation cylinder is smaller than the diameter of the upper end of the conical tube, and the diameter of the lower end of the separation cylinder is smaller than the diameter of the lower end of the conical tube.

[0009] Preferably, the upper end of the guide cylinder is conical and the lower end is cylindrical, a conical chamber is provided inside the guide cylinder, the diameter of the upper end of the guide cylinder is smaller than the diameter of the lower end of the separating cylinder, and the diameter of the lower end of the guide cylinder is smaller than the diameter of the connection between multiple conical tubes.

[0010] Preferably, a plurality of fixing blocks are fixed to the outer wall of the guide cylinder along its circumference, and the guide cylinder is fixedly connected to the inner tube via the fixing blocks.

[0011] Preferably, the diameter of the lower water outlet is smaller than the diameter of the upper water outlet, and the diameter of the upper water outlet is smaller than the diameter of the water inlet.

[0012] Preferably, the upper end of the water guide ring is connected to the lowest point of the lower end of the tapered tube.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. A separation cylinder is arranged in the conical tube, a guide cavity is formed between the separation cylinder and the conical tube, and a chamber is formed between the separation cylinder, the guide cylinder and the conical tube. The lower end of the chamber is bent upward. After the steam enters the interior of the inner tube through the air inlet, part of the steam directly passes through the separation cylinder and enters the next conical tube, and part of the steam moves toward the interior of the separation cylinder through the guide cavity formed between the separation cylinder and the conical tube, colliding with the steam that directly passes through the separation cylinder, thereby forming an obstruction to the steam that directly passes through the separation cylinder, causing the steam to exist in the inner tube for a longer time, thereby causing the steam to condense for a longer time, thereby improving the condensation efficiency of the steam. At the same time, the condensation effect of the steam can also be guaranteed when the steam is sufficient.

[0015] 2. Part of the steam that moves toward the inside of the separation tube through the guide cavity formed between the separation tube and the tapered tube is blocked by the steam that directly passes through the separation tube, resulting in a large amount of steam gathering here and causing the temperature of this part to be higher. A heat dissipation ring is provided on the outside of the tapered tube for heat conduction, which quickly exchanges heat with cooling water to ensure the condensation of steam. At the same time, the water inlet is set close to the upper water outlet, and the diameter of the upper water outlet is smaller than that of the lower water outlet. The diameter of the upper water outlet is smaller than that of the water inlet, so that the water flow from the water inlet enters the inside of the outer tube and moves in two directions of the upper water outlet and the upper water outlet, and a large amount of water flows out from the upper water outlet, and a small amount of water flows out from the lower water outlet. Since the steam enters from the air inlet, the steam temperature of the inner tube at the upper water outlet is higher, and a large amount of water will directly exchange heat with the steam at the upper end of the inner tube. The exchanged water quickly flows out from the upper water outlet, ensuring the condensation of the steam at the upper end of the inner tube. At the same time, part of the cooling water flows to the upper water outlet, which also ensures the condensation of the condensed water at the lower end of the inner tube.

Water is drained through the upper water outlet 102 and the lower water outlet 103, which is conducive to discharging the cooling water for heat exchange, so that the cooling water is circulated to ensure the condensation effect of the device, and a water inlet 101 is provided on the outer wall of the outer tube 1 and near the upper water outlet 102, the diameter of the lower water outlet 103 is smaller than the diameter of the upper water outlet 102, the diameter of the upper water outlet 102 is smaller than the diameter of the water inlet 101, and the water intake of the water inlet 101 is slightly greater than or equal to the lower water outlet. The sum of the water outputs of the upper water outlet 103 and the upper water outlet 102, the water inlet 101 is set close to the upper water outlet 102, and the diameter of the upper water outlet 102 is smaller than the lower water outlet 103, and the diameter of the upper water outlet 102 is smaller than the diameter of the water inlet 101, so that the water flow from the water inlet 101 enters the inner part of the outer tube 1 and moves in two directions of the upper water outlet 102 and the upper water outlet 102, and a large amount of water flows out from the upper water outlet 102, and a small amount of water flows out from the lower water outlet 103. Since the steam enters from the air inlet 203, the steam temperature of the inner tube 2 at the upper water outlet 102 is higher, and a large amount of water will directly exchange heat with the steam at the upper end of the inner tube 2. The exchanged water quickly flows out from the upper water outlet 102, which ensures the condensation of the steam at the upper end of the inner tube 2. At the same time, part of the cooling water flows to the upper water outlet 102, which also ensures the condensation of the condensed water at the lower end of the inner tube 2.

At the same time, a chamber is formed between the separation tube 3, the guide tube 4 and the conical tube 201, and the lower end of the chamber is bent upward. After the steam enters the interior of the inner tube 2 through the air inlet 203, part of the steam directly passes through the separation tube 3 and enters the next conical tube 201, and part of the steam moves toward the interior of the separation tube 3 through the guide cavity formed between the separation tube 3 and the conical tube 201, colliding with the steam that directly passes through the separation tube 3, forming an obstruction to the steam that directly passes through the separation tube 3, so that the steam exists in the inner tube 2 for a longer time, and then the steam is condensed for a longer time, which improves the condensation efficiency of the steam. At the same time, the condensation effect of the steam can also be guaranteed when the steam is sufficient. The upper end of the water guide ring is connected to the lowest point of the lower end of the conical tube 201, which is beneficial to guide the water into the collection bottle after the steam is condensed into water.

[0030] See also Figure 4 , Figure 5 and Figure 6The diameter of the upper end of the separation cylinder 3 is smaller than the diameter of the upper end of the tapered tube 201, and the diameter of the lower end of the separation cylinder 3 is smaller than the diameter of the lower end of the tapered tube 201.

When the steam enters the interior of the inner tube 2, it is beneficial to separate the steam and disperse part of the steam. After the steam enters the interior of the inner tube 2 through the air inlet 203, part of the steam directly passes through the separation cylinder 3 and enters the next tapered tube 201. Part of the steam passes through the guide cavity formed between the separation cylinder 3 and the tapered tube 201 and moves toward the interior of the separation cylinder 3, colliding with the steam that directly passes through the separation cylinder 3.

The separation cylinder 3 and the guide cylinder 4 are fixed by the connecting blocks 301 and the fixing blocks 401, which ensures the fixation of the separation cylinder 3 and the guide cylinder 4 and prevents the separation cylinder 3 and the guide cylinder 4 from being suspended without support.

[0031] When the utility model is used:

[0032] First, the device is placed vertically, the water inlet 101 is connected to the cooling water inlet pipe, the water outlet pipe is connected to the upper water outlet 102 and the lower water outlet 103, the steam pipe is connected to the air inlet 203, and the collecting bottle is connected to the sampling port 204;

[0033] Then, the circulating cooling water flows. Since the diameter of the sampling port 204 is smaller than the diameter of the air inlet 203 and the diameter of the water inlet 101 is larger than the diameter of the upper water outlet 102, the cooling water will fill the interior of the inner tube 2.

[0034] Then, pure steam enters the inner tube 2 through the air inlet 203, part of the steam directly passes through the separation tube 3 and enters the next tapered tube 201, and part of the steam passes through the guide cavity formed between the separation tube 3 and the tapered tube 201 and moves toward the inside of the separation tube 3, colliding with the steam that directly passes through the separation tube 3, thereby forming an obstruction to the steam that directly passes through the separation tube 3, causing the steam to exist in the inner tube 2 for a longer time, thereby causing the steam to condense for a longer time, and the steam condenses to form water, which is guided into the collection bottle through the water guide ring;

[0035] Finally, part of the steam moving toward the interior of the separation tube 3 through the guide cavity formed between the separation tube 3 and the tapered tube 201 is blocked by the steam directly passing through the separation tube 3, resulting in a large amount of steam gathering here and causing the temperature of this part to be higher. A heat dissipation ring 202 is provided on the outside of the tapered tube 201 for heat conduction, which quickly exchanges heat with cooling water to ensure the condensation of steam. At the same time, the water inlet 101 is set close to the upper water outlet 102, and the diameter of the upper water outlet 102 is smaller than that of the lower water outlet 103, and the diameter of the upper water outlet 102 is smaller than that of the water inlet 101, so that the water inlet After the water flows from the outlet 101 into the outer tube 1, it moves toward the upper water outlet 102 and the upper water outlet 102, and a large amount of water flows out from the upper water outlet 102, and a small amount of water flows out from the lower water outlet 103. Since the steam enters from the air inlet 203, the steam temperature of the inner tube 2 at the upper water outlet 102 is relatively high, and a large amount of water will directly exchange heat with the steam at the upper end of the inner tube 2. The exchanged water flows out quickly from the upper water outlet 102, ensuring the condensation of the steam at the upper end of the inner tube 2. At the same time, part of the cooling water flows to the upper water outlet 102, which also ensures the condensation of the condensed water at the lower end of the inner tube 2.
