Description

Heating chamber of Liangwen evaporator

Technical Field

The invention relates to the technical field of evaporators, in particular to a heating chamber of a Levenberg evaporator.

Background

The Leiwen evaporator has high production capacity in the evaporator, is suitable for caustic soda factory with high yield, and features that one boiling chamber is added to the heating chamber, and the static pressure produced by the liquid level in the heating chamber makes the liquid in the heating chamber boil continuously after the liquid in the boiling chamber is reduced in pressure, so as to reduce scaling in the heating chamber well, but the heating chamber of available Leiwen evaporator has some problems:

1. the heating tube in the existing heating chamber is a simple tube, the solution rises in the heating tube, and the solution is heated by heat transfer through the heating tube wall, while the existing heating tube has a smooth inner wall, the liquid is likely to form a fluid film on the inner wall, the fluid film can greatly reduce the heat exchange efficiency between the liquid in the film and the heating tube wall, and the liquid flows regularly and stably in the heating tube, and the combination of the two can greatly influence the heating efficiency of the heating tube, so that the working efficiency of the whole evaporator is reduced.

2. The heat source of the existing heating chamber is external heating steam, the steam is introduced into the heating chamber, and the heating is realized by heat exchange between the heating pipe and liquid, but most of the existing steam inlets are arranged at the upper part of the heating chamber, because the high-temperature steam is fed in, the upper part of the whole heating chamber has very high hot steam content and is less downwards, the heat distribution of the whole heating chamber is extremely uneven, especially the bottom part has extremely low liquid heating effect, the bottom part does not have preheating effect, the preset heating temperature is difficult to achieve by directly and intensively heating the top part by the high-temperature steam, and the existing steam inlet is only connected to one side of the heating chamber by a pipeline, so that the temperature of the side close to the steam inlet is very high, and the temperature of the side far away from the inlet is low, so that the heating pipe in the heating chamber is heated unevenly, not only the heat utilization rate is reduced, but also the heat exchange of the heating pipe far away from the steam inlet is reduced, and the uniform and efficient heating effect is difficult to achieve.

To this end, we propose a heating chamber for a lewen evaporator.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, a heating chamber of a lewy evaporator includes a heating chamber 1, a boiling chamber 2 is fixedly connected to the upper portion of the heating chamber 1, an inclined bottom 3 is fixedly installed at the bottom of the inner wall of the heating chamber 1, a heating pipe 4 is fixedly installed inside the heating chamber 1, a turbulent flow 5 is fixedly installed inside the heating pipe 4, a steam pipe 6 is fixedly connected to one side of the heating chamber 1, a steam spraying box 7 is fixedly installed at one end of the steam pipe 6, a steam nozzle 8 is opened on the steam spraying box 7, and a condensed water outlet 9 is fixedly installed at the bottom of one side of the heating chamber.

Wherein, the incline direction of the inclined bottom 3 is towards one side of the condensed water outlet 9, the condensed water is condensed after the heating steam is absorbed by the liquid in the heating pipe 4, the condensed water can quickly flow to the condensed water outlet 9 along the inclined edge of the inclined bottom 3 from the inclined bottom 3 after becoming the condensed water, and then is discharged from the condensed water outlet 9 to the heating chamber 1, the quick discharge of the condensed water can avoid the heat of the condensed water accumulated and absorbed in the heating chamber 1, and the heat absorbed in the condensed water can not be well utilized, which causes the heat waste, and the design of the inclined bottom 3 can further improve the utilization rate of the heating steam in the heating chamber 1.

Wherein, the even rotatory distribution that rises of indiscriminate fluid 5 is on the inner wall of heating pipe 4, the distribution that rotatory rises can be so that indiscriminate fluid 5 on the perpendicular line can stagger the distribution, make liquid keep the flow direction route of broken line on the perpendicular all the time, can not appear because the fixed liquid that leads to of the route of fluid on the perpendicular direction produces the fluid film, the high efficiency of the heat transfer of heating pipe 4 has been guaranteed, indiscriminate fluid 5 is the toper, can cut the fluid, it is mixed and disorderly to combine the flow of its distribution can be fine assurance liquid, can be so that the inside liquid of heating pipe 4 can be even carry out the heat exchange, and the heat exchange efficiency is improved.

Wherein, steam spray box 7 is cylindrical, the one end that steam spray box 7 was installed to steam pipe 6 is located the inside center of heating chamber 1, steam spout 8 encircles and sets up in steam spray box 7's side, after heating steam got into steam spray box 7 from steam pipe 6, because steam spray box 7 was in central point on this horizontal plane in heating chamber 1 inside, heating steam from steam spout 8 to the even injection all around of heating chamber 1 inside, the condition that traditional one side directly lets in hot steam and leads to the import department high temperature and keep away from the temperature of import low has been changed, make inside heating pipe 4 be heated more evenly the time also further improved the utilization ratio of heating steam.

Wherein, the bottom in heating chamber 1 one side is installed to steam pipe 6, change the tradition and set up the design in heating chamber 1 upper portion one side with the heating steam import, the design of bottom can be fine utilizes the rising effect of hot steam to let it rise naturally from the inside bottom of heating chamber 1, combine the injection effect of steam spout 8, can guarantee the even distribution of heat from the top down in whole heating chamber 1 well, can guarantee like this that heating pipe 4 carries out the even high efficiency of heat exchange in heating chamber 1 inside, and the bottom can not lead to the very low condition of heating effect of the inside bottom of heating chamber 1 because the heat can not in time supply yet, the work efficiency of whole evaporimeter has been improved.

The operating principle is that liquid enters the heating pipe 4 from the bottom of the heating chamber 1, the liquid moves upwards in the heating pipe 4, meanwhile, heating steam enters the steam spraying box 7 from the steam pipe 6, the steam spraying box 7 uniformly sprays the heating chamber 1 through a steam nozzle 8 formed in the steam spraying box 7, heat of the heating steam is exchanged with the liquid in the heating chamber through the heating pipe 4, and the condensed steam forms liquid to flow to the condensate water outlet 9 along the inclined bottom 3 and flows out of the condensate water outlet 9.
