[0026] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0027] like Figure 1-Figure 3 As shown, the utility model is an aluminum ash disposal MVR evaporator, comprising:

[0028] An MVR evaporation structure 1, wherein the interior of the MVR evaporation structure 1 is hollow to form a compression chamber 3, a steam pipe 4 is installed on one side of the MVR evaporation structure 1, and the steam pipe 4 is connected to the compression chamber 3; the other end of the steam pipe 4 is connected to the gas outlet of the boiler;

[0029] A compression structure 2, wherein the compression structure 2 is installed at the bottom of the MVR evaporation structure 1, and a compression end of the compression structure 2 is placed in the MVR evaporation structure 1 to perform preliminary compression on the steam;

[0030] The MVR evaporator body is connected to the MVR evaporation structure 1 through a pipeline, and plays a role in secondary steam compression.

[0031] The compression structure 2 includes a lifting cylinder 5 and a compression plate 6 arranged at the bottom of the MVR evaporation structure 1;

[0032] The compression plate 6 is arranged in the compression chamber 3 of the MVR evaporation structure 1, and the output shaft of the lifting cylinder 5 passes through the MVR evaporation structure 1 and is connected to the compression plate 6 of the compression chamber 3, and the steam in the compression chamber 3 is compressed by the compression plate 6; a retaining ring 7 is arranged in the center of the compression chamber 3, and the compression plate 6 is limited by the retaining ring 7.

[0033] The upper end of the MVR evaporation structure 1 is provided with a compressed steam outlet 8, and the compressed steam outlet 8 is connected to a pipeline; an outlet valve 10 is provided between the compressed steam outlet 8 and the pipeline.

[0034] Among them, a water outlet 11 is arranged at the lower part of the other side of the MVR evaporation structure 1, and a water outlet pipe 12 is connected to the water outlet 11, and a water outlet valve 13 is arranged between the water outlet pipe 12 and the water outlet 11; the position of the water outlet 11 is flush with the upper end surface of the retaining ring 7, when the compression plate 6 of the compression structure 2 rises to the retaining ring 7, the liquid in the compression chamber 3 flows out from the water outlet 11; the other end of the water outlet pipe 12 is connected to the boiler to send the filtered water back into the boiler.

[0035] In addition, a breathable plate 14 is arranged above the retaining ring 7 of the compression chamber 3 , and breathable holes are arranged on the breathable plate 14 . When the steam is compressed, the liquid remains on the breathable holes and is filtered, and then drips onto the compression plate 6 .

[0036] An air intake valve 16 is provided at the connection point between the steam pipe 4 and the compression chamber 3 , and steam is delivered into the compression chamber 3 through the air intake valve 16 .

[0037] In addition, a mounting seat 15 is fixed below the MVR evaporation structure 1 , and a control panel is provided on the mounting seat 15 , and the control panel is connected to control the lifting cylinder 5 , the air outlet valve 10 , the water outlet valve 13 and the air inlet valve 16 .

[0038] Here’s how it works:

[0039] The steam generated by the boiler enters the compression chamber of the MVR evaporation structure through the steam pipe; at this time, the compression structure is in the MVR evaporation structure, and the steam entering the compression chamber is preliminarily compressed; the preliminarily compressed steam passes through the compression steam outlet and is compressed again by the compression system in the MVR evaporator body. This process increases the temperature and pressure of the steam and accelerates the evaporation process;

[0040] High-pressure steam causes the treated liquid (such as water in aluminum ash) to evaporate in the main body of the MVR evaporator. The evaporated steam can be recycled back to the evaporation process for reuse, while the condensed liquid passes through the compression plate;

[0041] When the compression plate rises to the retaining ring, the liquid flows out through the water outlet; the liquid compressed in the compression chamber is sent back to the boiler through the water outlet pipe, realizing the recycling of water resources; at the same time, the air inlet valve is used to control the new steam to enter the compression chamber to maintain the continuous operation of the evaporator.

[0042] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
