Description

Technical Field

[0001] The utility model belongs to the field of kitchen waste water treatment equipment and relates to a washable MVR compressor volute. Background Art

[0002] When the MVR evaporation system is used to treat kitchen waste water, during the evaporation process, the oil in the feed can easily volatilize and condense on the volute and impeller of the compressor, reducing the working efficiency of the compressor, destroying the dynamic balance of the impeller, and causing the compressor to vibrate abnormally, causing the motor shaft displacement alarm to be too large and shut down, and even causing the impeller and volute to be scratched and torn due to surface scaling, seriously affecting the normal operation of the MVR evaporation system. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a cleanable MVR compressor volute, which dissolves and flushes oil by injecting steam at a certain pressure and temperature to achieve the purpose of cleaning oil. The device has the advantages of simple structure, easy use and significant effect, and has broad application prospects in MVR compressor cleaning.

[0004] The specific technical solution adopted by the utility model to achieve the above purpose is:

[0005] A washable MVR compressor volute comprises a main body, a steam inlet and a sewage outlet, wherein the steam inlet and the sewage outlet are arranged on the main body.

[0006] As a further optimization of the above solution, the steam inlet is at the upper part of the main body, and the sewage outlet is arranged at the bottom of the main body; the steam enters the main body from the steam inlet and flows out of the main body from the sewage outlet.

[0007] As a further optimization of the above scheme, the pressure range of the steam is between 0.1-0.2 MPa, the temperature is between 100-120° C., and the flushing time is controlled between 2-5 minutes.

[0008] The beneficial effects of the utility model are as follows: the utility model discloses a MVR compressor volute that can be cleaned, and steam of a certain temperature and pressure is added from the steam inlet to soften and dissolve the oil stains adsorbed on the air collecting ring, bracket, impeller and the inner surface of the volute, and the oil stains are washed out from the cleaned surface, and the separated oil stains are mixed with steam and flow out from the sewage outlet. The device has the advantages of simple structure, convenient use and significant effect, and has a wide application prospect in MVR compressor cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0027] Example:

[0028] like Figure 1-Figure 15 As shown, a washable MVR compressor volute includes a main body, a steam inlet and a sewage outlet, wherein the steam inlet and the sewage outlet are arranged on the main body.

[0029] As a further optimization of the above solution, the steam inlet is at the upper part of the main body, and the sewage outlet is arranged at the bottom of the main body; the steam enters the main body from the steam inlet and flows out of the main body from the sewage outlet.

[0030] As a further optimization of the above scheme, the pressure range of the steam is between 0.1-0.2 MPa, the temperature is between 100-120° C., and the flushing time is controlled between 2-5 minutes.

[0031] The working principle of the utility model will be explained below from two working states: normal operation of the MVR evaporation system, discharge of concentrated liquid, and cleaning and maintenance of the MVR compressor.

[0032] The instructions for use of this utility model are as follows:

[0033] First, assemble the main body 1, the air collecting ring 4, the bracket 5 and the impeller 6 into an MVR compressor, and connect the relevant pipelines and pipe fittings to prepare for the operation of the MVR evaporation system.

[0034] When the MVR evaporation system is operating normally, the steam inlet 2 and the sewage outlet 3 are closed, the air collecting ring 4 and the compressor outlet 7 are opened, the MVR compressor starts to run, and the evaporated material enters the main body 1 from the air collecting ring 4, the bracket 5, and the impeller 6 for compression and is discharged from the compressor outlet 7. This process continues until the concentrated liquid of the evaporated material reaches the discharge level.

[0035] When the MVR evaporation system discharges the concentrated liquid, the MVR compressor starts cleaning and maintenance, the MVR compressor stops running, the steam inlet 2 and the drain port 3 are opened, the air collecting ring 4 and the compressor outlet 7 are closed, and the steam enters the main body 1 from the steam inlet 2 to soften and dissolve the oil adsorbed on the main body 1, the air collecting ring 4, the bracket 5 and the inner surface of the impeller 6, and rinses the oil from the cleaned surface. The separated oil is mixed with steam and flows out of the main body 1 from the drain port 3 until it is cleaned.

[0036] After the cleaning and maintenance of the MVR compressor is completed, close the steam inlet 2 and the sewage outlet 3, open the air collecting ring 4 and the compressor outlet 7, restore the MVR compressor to a normal working state, and prepare for the normal operation of the MVR evaporation system.

[0037] When the utility model cleans and maintains the MVR compressor, the steam pressure is controlled between 0.1-0.2MPa, the temperature is controlled between 100-120°C, the flushing time is controlled between 2-5 minutes, and the steam temperature, pressure and flushing time should be adjusted according to the actual sewage discharge situation to ensure the working quality and effect of the utility model to meet the needs of oil pollution cleaning.
