Description

Technical Field

[0001] The invention relates to the technical field of evaporators, and in particular to an energy storage type multiple-effect evaporator. Background Art

[0002] One of the ways to treat sewage is to send the sewage to be treated into the evaporator in the form of evaporation. The sewage encounters high temperature, evaporates to form steam and is drawn out. The remaining sewage and impurities remain in the evaporator. The evaporator is cleaned regularly to ensure its continuous and reliable operation.

[0003] For example, the patent with application number "CN2021219541705" discloses a sewage evaporator, in which the tower body is provided with a chimney, a negative pressure vacuum section, a heat exchange section, a water collection section, a gas-liquid mixing section and a spray section from top to bottom. The heat exchange section is provided with a heat exchanger, and an air inlet is provided on the tower body of the gas-liquid mixing section, which is connected to the heating component, and a water inlet pipe is provided at the bottom of the tower body; sewage enters the tower body from the water inlet pipe, and forms a mist after being sprayed out from the nozzle, and forms rising small water droplets and water vapor after being heated by the hot air sprayed by the heating component, and the water collection section removes large particles of small water droplets, and the heat exchange section is heated again, and the membrane assembly in the negative pressure vacuum section is used to filter and remove small particles of water droplets and impurities, and finally the water vapor in gaseous state is discharged from the chimney. The device can realize the heating of part of the sewage into gaseous discharge, but it will form some concentrated sewage, which needs to be treated separately; the steps are relatively cumbersome and the evaporation effect is poor.

[0004] For example, the patent with application number "CN2015211060970" discloses a rapid evaporation sewage evaporator, including an evaporator, wherein: a water baffle is installed on the inner side of the top of the evaporator, and a plurality of holes are arranged on the water baffle; overflow ports are respectively arranged on the walls of the evaporator; a thermal resistor is arranged on the inner side of the bottom of the evaporator, an insulation layer is arranged between the outer wall and the inner wall of the evaporator, and a slag discharge port is arranged at the bottom of the evaporator; a gas collecting tank is installed on the top of the evaporator, and the gas collecting tank is connected to a first drying tank, and an acidic desiccant is arranged in the first drying tank. The evaporator injects high-concentration sewage into the nozzle and sprays it into the inner cavity of the evaporator at a high speed; the thermal resistor evaporates the medium; due to the design and installation position, area and other restrictions of the heating resistor, the overall evaporation efficiency is not high, the sewage treatment speed is low, and it is difficult to meet the needs of continuous operation; and debris adheres to the resistor, resulting in a continuous decrease in evaporation efficiency and troublesome maintenance.

[0005] For example, the patent with application number "CN2012203907591" discloses a chemical evaporator, which includes a cylinder, a first feed pipe, a second feed pipe, a reduced-pressure steam extraction pipe, an upper packing layer, a partition, a first lower packing layer, a second lower packing layer and a discharge pipe; a reduced-pressure steam extraction pipe communicating with the inner cavity of the cylinder is fixed at the upper end of the cylinder, a discharge pipe is provided at the bottom of the cylinder, a support leg is fixed at the lower end of the cylinder, an upper packing layer is fixed in the upper part of the cylinder, a partition is fixed in the cylinder below the upper packing layer along the front-to-back direction, there is a gap between the bottom of the partition and the bottom of the cylinder, and a first feed pipe is fixed in the cylinder on the left side of the upper end of the partition. The device uses stainless steel metal balls, which have a larger specific surface area, increase the evaporation treatment surface area of ​​sewage and accelerate the evaporation rate; however, since debris will adhere to the stainless steel metal balls, blockage and reduced efficiency will gradually occur over time; and the maintenance of the stainless steel metal balls as fillers is also extremely inconvenient; in addition, relying solely on the increased treatment surface area, the efficiency is still not very high; in addition, the incoming sewage is required to be high temperature, which requires the coordination of other equipment, and the overall effect is not good.

[0006] In summary, it can be seen that there are still some problems and shortcomings in the relevant equipment currently on the market. First of all, it is generally necessary to cooperate with other equipment to realize the entire sewage treatment process, which leads to a long overall treatment process, a large area occupied by the equipment, and correspondingly low efficiency. Secondly, low energy utilization is a more prominent problem; the sewage needs to be heated externally, or the sewage needs to be heated directly inside the evaporator; in this process, a large amount of energy is required to provide a high temperature environment, but the energy utilization is not efficient enough, and some energy is not effectively utilized, resulting in energy waste. In addition, the energy of steam has not been reasonably and effectively utilized, which further leads to high overall energy consumption. In addition, there are also inconveniences in cleaning and maintenance; due to the lack of convenient cleaning and maintenance mechanisms in the internal structure design, the operation is complicated, time-consuming and labor-intensive when cleaning and maintaining the evaporator, which increases the processing cost and difficulty.

[0044] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] Reference Figure 1-15 , an energy storage type multiple-effect evaporator, comprising an evaporating cylinder 2 filled with steel balls 1, and a preheating chamber 4 with a sewage pipe 3 reciprocatingly arranged inside.

[0046] This device is different from the traditional evaporator for sewage treatment. The heated steel ball 1 is designed to store energy to heat the sewage and form evaporation. At the same time, the preheating bin 4 is designed to cooperate with the evaporating cylinder 2 to preheat the sewage to be treated. A set of equipment has multiple functions and can directly complete the entire sewage treatment function.

[0047] like Figure 2 As shown, the evaporation tube 2 is cylindrical in shape as a whole, and is filled with a suitable number of steel balls 1; the sewage pipe 3 is arranged in a serpentine shape in the preheating chamber 4 to increase the length of the sewage pipe 3 in the preheating chamber 4, so that the sewage can be preheated for a longer time.

[0048] It should be noted that the size, quantity, filling height and other data of the steel balls 1 should be reasonably calculated and evenly filled according to the specifications of the evaporator tube 2, the amount of sewage to be treated, the treatment speed requirements, etc.

[0049] At the same time, a steam outlet 21 is provided at the top of the evaporating cylinder 2, and is connected to the steam inlet 41 at the lower part of the preheating chamber 4 through a pipeline; thereby, the steam generated in the evaporating cylinder 2 is recycled, the overall energy utilization rate is improved, and more energy is saved.

[0050] It is understandable that a steam outlet 42 is provided at the top of the preheating chamber 4; after preheating the sewage pipe 3, the steam is discharged to the outside of the preheating chamber 4. It should be noted that if the steam temperature at the steam outlet 42 is still high, it can be reused; or, the volume of the preheating chamber 4 can be increased to make the steam stay longer.

[0051] It can be understood that the inlet and outlet of the sewage pipe 3 are respectively arranged to penetrate the outside of the preheating chamber 4 to facilitate the connection of the pipeline; further, flanges or quick connectors are arranged at the ends of the inlet and outlet to facilitate the docking and assembly of the pipeline.

[0052] Preferably, the inlet of the sewage pipe 3 is located at the high end, and the outlet is located at the low end; thereby, a certain pressure difference is created, which can speed up the flow rate and reduce adhesion in the pipe.

[0053] It is important to note that the location of this setting is not mandatory.

[0054] In addition, the outlet of the sewage pipe 3 is connected to the water distribution pipe 5 arranged at the upper position inside the evaporating cylinder 2 through a pipeline; the preheated sewage is sent into the evaporating cylinder 2 through the water distribution pipe 5 to be evaporated; and the steam formed by evaporation enters the preheating chamber 4 for utilization.

[0055] When the device is used, the inlet end of the sewage pipe 3 is connected to the sewage to be treated, and the outlet end is connected to the water distribution pipe 5 of the evaporating cylinder 2; the sewage is preheated in the preheating chamber 4, and then dispersed through the water distribution pipe 5 and sprinkled onto the steel ball 1; the steel ball heated and storing energy heats the sewage at high temperature to form steam in the evaporating cylinder 2; impurities in the sewage remain on the steel ball 1 of the evaporating cylinder 2; at the same time, the formed steam enters the preheating chamber 4 to preheat the sewage pipe 3; after a period of use, the inside of the evaporating cylinder 2 and the steel ball 1 are cleaned.

[0056] It should be noted that a water collection pipe is provided at the bottom of the preheating chamber 4 to collect the condensed water or water vapor in the preheating chamber 4 .

[0057] In this device, steel balls 1 are filled in the evaporating cylinder 2 to directly heat the steel balls 1, which are used to store heat. The sewage is then heated and evaporated through the surface area of ​​the steel balls 1. The surface area is large and the evaporation efficiency is high. Without the need for other equipment, this device can realize the entire sewage treatment process without the need for transportation between equipment, further improving efficiency.

[0058] In this device, a preheating bin 4 is provided to pretreat the incoming sewage, thereby increasing the initial temperature of the sewage entering the evaporating cylinder 2, and further improving the treatment efficiency of the evaporator; the sewage pipe is arranged in a serpentine shape in the preheating bin 4, and the arrangement length of the sewage pipe 3 in the preheating bin 4 is increased, so that the sewage undergoes a longer preheating treatment and obtains more heating, further cooperating with the evaporating cylinder 2 to improve the overall treatment efficiency; and the evaporating cylinder 2 cooperates with the preheating bin 4 to realize the preheating process by recycling the steam generated in the evaporating cylinder 2; it significantly improves the overall energy utilization rate and is more energy-saving.

[0059] In some embodiments, a combustion chamber 22 is provided at the lower part of the evaporation cylinder 2 to transfer heat to the steel ball 1, so that the steel ball 1 is in a high temperature state; after the sewage enters, it comes into contact with the steel ball 1, quickly vaporizes and evaporates, and debris is attached to the surface of the steel ball 1.

[0060] It should be noted that the steel ball 1 used as the heating body is heat-resistant and corrosion-resistant, and its consumption during use is almost negligible. The service life of the steel ball 1 is extremely long, and there is almost no need to bear subsequent material costs; and the steel ball 1 can be cleaned during cleaning, which makes the operation more convenient.

[0061] It is understandable that the steel ball 1 should be made of a heat-resistant and corrosion-resistant material with high reliability; for example, 722M24 steel, 1.4845 stainless steel, SKD61, etc. Furthermore, a fire tube 6 with a closed top is provided in communication with the middle position of the top of the combustion chamber 22 .

[0062] It is understandable that since the combustion chamber 22 is located at the lower part, the temperature of the steel balls 1 in the lower layer will be high, but the temperature is difficult to transfer to the steel balls 1 in the upper layer; however, the sewage is distributed from above; this actually results in the upper steel balls with lower temperatures being the first to contact the sewage, and even the temperature may be extremely low; the overall evaporation efficiency is low and the effect is poor.

[0063] In this solution, after the fire tube is set, the flame can be guided upward to directly transfer heat to the upper steel ball 1; compared with the solution of only setting the combustion chamber 22, the heating speed and effect are greatly improved.

[0064] Furthermore, a plurality of flame-spraying holes 61 are provided on the outer ring side of the fire tube 6 .

[0065] As shown in the figure, a plurality of flame-spraying holes 61 are evenly, spaced apart and arranged around each layer; the distance between the flame-spraying holes 61 in each layer is kept consistent.

[0066] It is understandable that when the top is in a closed state, the flame can hardly reach the upper position; and the internal airflow must be blocked, further affecting the combustion effect of the flame; thus, directly affecting the evaporation effect.

[0067] In this solution, after the flame hole 61 is provided, the fire tube 6 also forms a chimney effect; the flame is sucked, and more flames can be emitted from the flame hole 61; the overall combustion is more vigorous, and the heating efficiency and heating effect of the steel ball 1 are also better.

[0068] Furthermore, in order to avoid the impact of sewage on combustion, we also set up corresponding shielding structures.

[0069] Specifically, the outer ring side of the fire tube 6 is provided with a ring retaining edge 62 which is inclined downward on the outer side, corresponding to the upper position of the flame-spraying hole 61 .

[0070] like Figure 3-7 As shown; the barrier structure is set to prevent unvaporized sewage from entering.

[0071] Preferably, the gap between the two layers of annular retaining edges 62 is smaller than the diameter of the steel ball 1. In other words, the steel ball 1 will not get stuck between the two layers of annular retaining edges 62; thus, the space for the flame to spray outward can be directly controlled by controlling the inner and outer diameter difference of the annular retaining edges 62.

[0072] In some embodiments, the top surface of the combustion chamber 22 is in the shape of a top cone; it not only has a larger combustion contact surface; at the same time, it guides the steel ball 1, making it easier to cooperate with the subsequent ball discharge process.

[0073] In some embodiments, a volleyball mechanism 7 is provided at the lower outer side of the evaporating cylinder 2 .

[0074] It is understandable that the purpose of the evacuation mechanism 7 is to discharge part or all of the internal steel balls 1 after a certain period of time for cleaning; and to make its operation fully controllable.

[0075] It is understandable that, in the conventional form, if the steel ball 1 needs to be discharged, it needs to be taken in and placed from the top; if the opening is opened from the bottom, the ball discharge will be uncontrollable (under the action of pressure, the steel ball tilts out); and the ball discharge from various places cannot be uniform, and the partial ball discharge cannot be controlled, etc.

[0076] After setting up this component, the ball output can be well controlled and the ball output position can be controlled.

[0077] Specifically, the ball discharge mechanism 7 includes: a ball outlet hole 71 surrounding the evaporator tube 2 , a lower opening enclosure 72 fixedly connected to the outer side of the evaporator tube 2 , and a ball outlet plate 73 rotatably arranged below the lower opening enclosure 72 .

[0078] It should be noted that the position of the ball outlet hole 71 is set according to the number of steel balls 1 that can be placed in the outermost layer of the evaporating tube 2. For example, if the outermost layer can accommodate 28 steel balls 1, 28 ball outlet holes are opened.

[0079] In addition, one or more ball outlets 731 are formed on the ball outlet plate 73 .

[0080] During each rotation, after the ball outlet 731 corresponds to the ball outlet hole 71 at a certain position, the steel ball 1 can be discharged outward through the ball outlet hole 71, the lower opening enclosure 72, and the ball outlet plate 73 in sequence.

[0081] It should be noted that by providing several ball outlets 731, steel balls in several positions can be discharged simultaneously. As for whether to provide one or more, it can be provided according to the needs.

[0082] In this solution, the steel balls 1 at different positions are taken out respectively by rotating the ball-out plate 73; the operation is convenient, efficient, and fully controllable.

[0083] Preferably, the ball outlet hole 71 is a door-shaped structure with a semicircular top.

[0084] As shown in the figure, the inner diameter of the lower part of the gate-like structure is not less than the size of the upper part, which makes it easier for the steel ball 1 to pass through.

[0085] It can be understood that since the ball outlet hole 71 and the lower opening enclosure 72 are always connected, some steel balls 1 will be temporarily stored in the lower opening enclosure 72; when in use, after the ball outlet 731 corresponds to a certain steel ball 1, the steel ball 1 is discharged; and by rotation, the ball outlet at each position can be controlled to be relatively uniform.

[0086] In some embodiments, ball spacers 721 are disposed at intervals in the lower opening enclosure 72 .

[0087] The ball stopper 721 is arranged corresponding to the ball outlet hole 71 and is located on both sides thereof to form a gap.

[0088] Therefore, only one steel ball 1 can be accommodated between two adjacent ball spacers 721, so that the steel ball 1 can be effectively controlled better.

[0089] In some embodiments, a ball volley tube 732 is disposed below the ball outlet 731 .

[0090] The steel ball 1 is guided by the additional ball volley tube 732; the lower end of the ball volley tube 732 can be provided with a conveying trough, a conveying pipe and other structures to directly guide the steel ball 1 to a suitable position.

[0091] In some embodiments, a lower ring 733 is provided on the inner side of the lower part of the ball outlet plate 73 to match the outer wall of the evaporator tube 2; an upper ring 734 is provided on the outer side of the upper part of the ball outlet plate 73 to match the outer wall of the lower opening enclosure 72; a gear ring is fixedly provided on the outer side of the lower ring 733 or the upper ring 734, and is transmission-connected to an external driving gear (not shown in the figure).

[0092] It should be noted that the two upper and lower ring bodies are provided to ensure and improve the stability of the ball outlet plate 73 during the rotation operation; they cooperate with the inner and outer equipment structures respectively, and have excellent stability.

[0093] It is understandable that a support ring fixedly connected to the evaporator tube 2 is provided at the lower end of the lower ring 733 to limit the ball outlet plate 73. The gear ring is matched with the driving gear, and the driving gear is driven by the power device; when rotating, the relative position of the ball outlet 731 changes.

[0094] In some embodiments, a ball adding mechanism 8 is provided on the upper outer side of the evaporating cylinder 2 .

[0095] It is understandable that after taking out some steel balls 1 from the bottom, the data of steel balls 1 in the evaporating tube 2 is insufficient, which will directly affect the efficiency of the evaporator; therefore, it is necessary to add material inside, and we have set up a ball adding structure accordingly.

[0096] Specifically, the ball adding mechanism 8 includes: a ball hole 81 surrounding the evaporator tube 2, an upper opening enclosure 82 fixedly connected to the outside of the evaporator tube 2, and a ball ring 83 rotatably arranged inside the evaporator tube 2 and corresponding to the ball hole 81; one or more ball openings 831 are opened on the ball ring 83.

[0097] For the structural settings here, please refer to the previous description.

[0098] Specifically, the number of the ball holes 81 does not need to be specially set, as long as it can be evenly distributed.

[0099] When in use, through the rotation of the goal ring 83, one or more goal openings 831 are overlapped with different goal holes 81 respectively, so that the steel ball 1 can be introduced into the interior to achieve ball addition.

[0100] Through the arrangement of the present application, under the rotation of the goal ring 83, goals are scored in sequence at different positions; the uniformity of each position during the ball adding process can be ensured, and the ball adding effect is good.

[0101] In some embodiments, a support ring fixedly connected to the evaporator tube 2 is provided at the lower end of the goal ring 83; the vertical movement of the goal ring 83 is limited by the support ring and the gravity of the goal ring 83.

[0102] At the same time, a plurality of driving components are arranged above the goal ring 83 to drive the rotation of the goal ring 83 .

[0103] Preferably, the driving component is a motor in a closed housing; a rubber wheel is provided on the output shaft of the motor, which is pressed against the inner side of the ball ring 83 to drive it to rotate; or, a gear is provided on the output shaft of the motor, and teeth are correspondingly provided on the inner ring side of the ball ring 83, and rotational drive is performed through meshing.

[0104] In some embodiments, a vertically movable cover 84 is disposed above the upper opening enclosure 82 .

[0105] It should be noted that the cover 84 is provided to seal the upper opening enclosure 82 when no balls are added to prevent the steam from overflowing.

[0106] In some embodiments, the water distribution pipe 5 includes multiple layers of coaxially arranged and interconnected ring pipes.

[0107] Correspondingly, a water outlet is provided at the lower end of the annular tube; as shown in the figure, by setting up the multi-layer annular tube, the comprehensiveness of water distribution coverage can be improved, so that the steel balls 1 used are relatively uniform.

[0108] Furthermore, the height of the multi-layer annular pipe gradually decreases from the outside to the inside; it can better match different water distribution ranges, and the water pressure in the inner circle is generally lower, which can be compensated by the height setting.
