Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to a high thermal conductivity wastewater evaporator. Background Art

[0002] The basic principle of the evaporator is to use the property of liquid to evaporate when it comes into contact with a higher temperature surface, thereby absorbing heat from the surrounding environment and converting the liquid into a gas state. The evaporator usually contains a series of pipes, coils or other surfaces to increase the contact area and promote the evaporation of the liquid.

[0003] After searching, the authorization announcement number CN 219058593 U discloses a high thermal conductivity wastewater evaporator, which relates to the technical field of wastewater evaporators; the above technical scheme includes an evaporator body, both ends of the evaporator body are fixedly connected with guide plates, the guide plate at the upper end is threadedly connected with an upper cover, and the guide plate at the lower end is threadedly connected with a lower cover, an exhaust pipe is fixedly sleeved on the upper cover, and a water outlet pipe and a crystal row tube are fixedly sleeved on the lower cover, a plurality of air channels opened in the shell of the evaporator body are connected with a plurality of in-line tubes inside through the guide plate, so that the thermal conductivity is enhanced and the heat exchange rate of the organic waste liquid is improved; the organic waste water is subjected to multiple reciprocating deflections in the evaporator body through a plurality of first partitions and a plurality of annularly distributed independent chambers separated by a second partition, so that the retention time of the organic waste water in the evaporator body is prolonged, thereby making the concentration of the organic waste water more thorough.

[0004] The above-mentioned technical solution and the existing evaporator generally only have one steam inlet. When external steam enters the evaporator through one inlet, it is difficult to heat the internal temperature of the evaporator quickly and evenly. Due to the obstruction of the in-line pipes in the evaporator, the side of the evaporator away from the steam inlet is preheated slowly, making it difficult for the in-line pipes distributed at different positions inside the evaporator to be heated efficiently and evenly.

[0005] To this end, we propose a high thermal conductivity wastewater evaporator. Utility Model Content

[0006] The utility model mainly solves the above technical problems and provides a wastewater evaporator with high thermal conductivity.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high thermal conductivity wastewater evaporator, comprising an evaporator body, an evaporator feed part is provided on the evaporator body, a plurality of groups of in-line tube assemblies are provided inside the evaporator body, the plurality of groups of in-line tube assemblies are evenly distributed inside the evaporator body, the in-line tube assemblies include a vertical tube, and a plurality of groups of hollow balls connected to the vertical tube are equidistantly provided on the vertical tube;

[0008] The outer wall surface of the evaporator body is provided with a steam introduction pipe, and the outer side surface of the evaporator body is respectively provided with an exhaust pipe and a liquid discharge pipe.

[0009] Preferably, a liquid guide tube is provided on the top surface of the evaporator inlet portion, and a guide plate and a uniform distribution plate are provided inside the evaporator inlet portion.

[0010] Preferably, the uniform distribution plate is penetrated with densely distributed openings.

[0011] Preferably, a connecting pipe is fixedly spliced ​​at the upper end of the vertical pipe, and the upper end of the connecting pipe is fixedly connected to the uniform distribution plate through a corresponding opening. The wastewater is introduced into the evaporator feed part through the liquid guide pipe, and the wastewater introduced into the evaporator feed part is evenly introduced into the uniform distribution plate through the guide plate, and the wastewater is introduced into multiple groups of in-line tube assemblies through multiple groups of openings.

[0012] Preferably, the gaps between the multiple groups of risers are wavy.

[0013] Beneficial Effects

[0014] The utility model provides a high thermal conductivity wastewater evaporator. It has the following beneficial effects:

[0015] (1) In this high thermal conductivity wastewater evaporator, external steam is introduced into the evaporator body through a steam inlet pipe, and the high-temperature steam in the evaporator body heats the multiple groups of in-line tube assemblies in the evaporator body, thereby heating the wastewater inside the vertical pipe. When the steam enters the evaporator body, it is dispersed in the gaps formed between the multiple groups of in-line tube assemblies through the multiple groups of hollow balls equidistantly arranged on the vertical pipe. The gap formed between two adjacent groups of hollow balls is a region with a large front end, a small middle, and a large rear end. When the steam passes through such a region, it is similar to passing through a Lafarge tube, so that the steam can be fully dispersed in the evaporator body, thereby improving the dispersion efficiency of the steam in the evaporator body, achieving the effect of improving the performance of the in-line tube assemblies, and facilitating uniform heating in the evaporator body.

[0016] (2) This high thermal conductivity wastewater evaporator has multiple groups of hollow balls on the vertical pipe.

[0027] The outer wall of the evaporator body 1 is provided with a steam introduction pipe 8, and external steam is introduced into the evaporator body 1 through the steam introduction pipe 8. The high-temperature steam in the evaporator body 1 heats the multiple groups of in-line tube assemblies 7 in the evaporator body 1, thereby heating the wastewater in the vertical pipe 701. The multiple groups of hollow balls 702 are equidistantly arranged on the vertical pipe 701, so that the gaps between the multiple groups of vertical pipes 701 are wavy. In this way, when the steam enters the evaporator body 1, the steam is dispersed in the gaps formed between the multiple groups of in-line tube assemblies 7, and the gaps between two adjacent groups of hollow balls 702 are wavy. The gap formed between the two ends of the evaporator 701 is a region with a large front end, a small middle end, and a large rear end. When the steam passes through such a region, it is similar to passing through a Laval tube, so that the steam can be fully dispersed in the evaporator body 1, thereby improving the dispersion efficiency of the steam in the evaporator body 1, thereby improving the thermal conductivity in the evaporator body 1. At the same time, through the multiple groups of hollow balls 702 provided on the vertical pipe 701, the outer surface area of ​​the hollow balls 702 is large, so that the contact area between the hollow balls 702 and the steam is also greatly increased, further improving the thermal performance of the in-line tube assembly 7, and facilitating the rapid heating and evaporation of the wastewater in the in-line tube assembly 7;

[0028] An exhaust pipe 9 and a drain pipe 10 are respectively disposed on the outer side of the evaporator body 1 , through which the evaporated gas is discharged, and through which the wastewater compressed liquid is discharged to the outside.

[0029] The working principle of this utility model:

[0031] External steam is introduced into the evaporator body 1 through the steam inlet pipe 8, and the high-temperature steam in the evaporator body 1 heats the multiple groups of in-line tube assemblies 7 in the evaporator body 1, thereby heating the wastewater inside the vertical pipe 701. The multiple groups of hollow balls 702 are equidistantly arranged on the vertical pipe 701, so that the gaps between the multiple groups of vertical pipes 701 are wavy. In this way, when the steam enters the evaporator body 1, the steam is dispersed in the gaps formed between the multiple groups of in-line tube assemblies 7, and the gap formed between two adjacent groups of hollow balls 702 is an area with a large front end, a small middle, and a large rear end. When the steam passes through such an area, it is similar to passing through a Laval tube, so that the steam can be fully dispersed in the evaporator body 1, thereby improving the dispersion efficiency of the steam in the evaporator body 1.

[0032] The multiple groups of hollow balls 702 provided on the vertical pipe 701 have a larger outer surface area, so that the contact area between the hollow balls 702 and the steam is greatly increased, further improving the heating performance of the in-line pipe assembly 7 and facilitating rapid heating and evaporation of wastewater in the in-line pipe assembly 7.
