Description

Porous sapphire steam heating pipe

Technical Field

The utility model relates to a steam heating device technical field especially relates to a porous type sapphire steam heating pipe.

Background

The direct steam heating mode has the advantages of direct steam-liquid contact, rapid heating, simple heating equipment and low manufacturing cost, so the direct steam heating mode is widely applied to the industries of food, brewing, chemical engineering, metal surface treatment, metallurgy, mining and the like.

The existing method for direct steam heating is that a steam heating pipe with a hole at the bottom end is directly extended into reaction liquid, and steam enters the reaction liquid from the hole at the bottom end through a hollow steam heating pipe for heating. Because the aperture of the bottom opening of the steam pipe is large, the speed of steam entering the reaction liquid from the bottom opening is small, the stirring of the liquid in the kettle is small, the steam and the liquid are not fully mixed, the reaction cannot be completely carried out, and the heating effect is poor.

Aiming at the problems, the Chinese patent with publication number 202741106U, publication number 2013, 02/20, designs a direct steam heating device which is formed by connecting a steam pipe, a connecting piece, a buffer section and a nozzle in sequence, wherein the diameter of the buffer section is smaller than that of the steam pipe, the nozzle is of a conical structure, the device can accelerate the flow rate of heating steam sprayed from the nozzle, has good stirring effect on liquid in a kettle, and can improve the reaction speed of the liquid in the kettle to a certain extent, but the device arranges a steam outlet hole on the conical nozzle, on one hand, as the unit volume of steam flowing out is reduced, the heating efficiency is reduced, the steam and the reaction liquid cannot be fully and uniformly mixed, the expected heating effect cannot be achieved, on the other hand, as a steam heating pipe is generally made of stainless steel material, as the steam can intensively release a large amount of heat to generate bubble corrosion around the nozzle in the mixing process of the steam and the reaction liquid, the nozzle can be broken after long-term use, the speed of the nozzle breakage is aggravated when corrosive reaction liquid is heated, and therefore the replacement frequency of the steam heating pipe is inevitably increased, and the equipment cost is increased. Meanwhile, in the heating process, the device generates vibration and noise due to the impact of a large amount of collected steam water, the heat insulation layer of the equipment is damaged and falls off, and even the equipment is damaged, so that the safety production is threatened.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough of existence among the prior art, providing a simple structure, high temperature resistant, corrosion-resistant, the effectual porous type sapphire steam heating pipe of heating, enabling high-temperature steam and reaction liquid intensive mixing, can reach fine heating effect.

According to the technical scheme provided by the utility model, porous type sapphire steam heating pipe includes the heating pipe body, the heating pipe body has upper end and lower tip, characterized by: the upper end of the upper end part is provided with an opening, the lower end of the lower end part is closed, a plurality of steam jet holes are formed in the periphery of the radial pipe wall of the lower end part, and the lower end part is made of sapphire.

Further, the upper end portion and the lower end portion are integrally formed.

Further, the upper end portion and the lower end portion are detachably connected.

Further, the lower end part pipe diameter is the same as the upper end part pipe diameter.

Further, the lower end pipe diameter is larger than the upper end pipe diameter.

Further, the plurality of steam injection holes are evenly distributed on the circumference of the radial pipe wall.

The utility model discloses the lower tip of structure heating pipe body adopts the sapphire material, because of the peculiar high temperature resistant, corrosion resisting characteristic of sapphire, can overcome the use defect who adopts other materials, long service life, reduce cost, but the wide application is in the firing equipment of trades such as food, brewing, chemical industry, metal surface treatment, metallurgy, mining, the utility model discloses structure practicality is strong; through having seted up a plurality of steam jet orifices on the radial pipe wall periphery at steam heating pipe lower tip, on the one hand can increase the unit outflow volume of heating steam and with the area of contact of reaction liquid, on the other hand, steam sprays inflow reaction liquid through a plurality of evenly distributed's of radial pipe wall aperture, the impact force is along horizontal direction evenly distributed, avoided traditional structure because of vibrations and the noise that steam high-speed injection inflow reaction liquid of steam from steam heating pipe's bottom trompil caused because the impact force is concentrated.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, the utility model relates to a porous sapphire steam heating pipe includes heating pipe body 1, and heating pipe body 1 has upper end 2 and lower tip 3, and upper end 2 and lower tip 3 can dismantle through integrated into one piece and connect and form upper end opening, lower extreme confined heating pipe body 1. Upper end 2 and lower tip 3 form upper end opening, lower extreme confined sapphire heating pipe body 1 through integrated into one piece, because of the peculiar high temperature resistant, the corrosion-resistant characteristic of sapphire, can overcome the service defect who adopts other materials, long service life, in addition, also can form through dismantling the connection heating pipe body 1, upper end 2 adopt stainless steel material, and lower tip 3 adopts sapphire material, and convenient the change saves the cost. Set up a plurality of evenly distributed's steam jet orifice 4 on the radial pipe wall periphery of the lower tip 3 of heating pipe body 1, high-temperature steam gets into heating pipe body 1 through heating pipe body 1 upper end 2 and again through lower tip 3, from the high-speed blowout of a plurality of evenly distributed's of the radial pipe wall of lower tip 3 in the reaction liquid that flows in, enable high-temperature steam and reaction liquid abundant contact and homogeneous mixing, simultaneously because the impact force of steam jet is along horizontal direction evenly distributed, and the impact force is dispersive, the problem of traditional structure because of vibrations and noise and the misce bene that the impact force concentrates on the steam and sprays inflow reaction liquid at a high speed from the bottom trompil of steam heating pipe is avoided.

As shown in fig. 1, the pipe diameter of the lower end part 3 of the heating pipe body 1 is the same as that of the upper end part 2, so that steam and reaction liquid can be mixed uniformly more fully, the pipe diameter of the lower end part 3 can be larger than that of the upper end part 2 as shown in fig. 2, the structure can increase the unit outflow volume of high-temperature steam and the contact area of the high-temperature steam and the reaction liquid, and the heating rate and the heating effect of the steam heating pipe are improved.
