Abstract
The utility model relates to a triple tandem high-temperature heat pump unit. Every heat pump (3) consists of a compressor (A1), a condenser (A2), an evaporator (A3) and an electronic expansion valve (A4) which form a heat pump loop. The triple tandem high-temperature heat pump unit is characterized in that: the condensers (A2) of three heat pumps (3) are communicated and connected in series through pipelines; the evaporators (A3) of the three heat pumps (3) are communicated and connected in series through pipelines; a clear water inlet pipe (2) is in communicated connection with a water inlet of the condenser (A2) of a first heat pump (31); a high-temperature waste water inlet pipe (1) is in communicated connection with the evaporator (A3) of a third heat pump (33); an outlet of the condenser (A2) of the third heat pump (33) is in communicated connection with a clear water inlet pipe (4); and the outlet of the evaporator (A3) of the first heat pump (31) is in communicated connection with a high-temperature waste water outlet pipe (5). In the triple tandem high-temperature heat pump unit, triple tandem heat pumps heat clear water for three times to ensure that high-temperature clear water which has the temperature of more than 90 DEG C and can meet the requirement of a production process can be obtained at a time.
Description
Technical field:
The utility model relates to the source pump technical field, more specifically to a kind of high temperature heat pump unit that is together in series by three heat pumps.
Background technology:
Dyeing is a kind of industry of high energy consumption; The dyeing waste water of its discharging every day is not only measured big but also is contained great amount of heat; Temperature is between 40-60 ℃; Existing source pump generally adopts the two-stage tandem source pump, and it can only be warmed up to clear water about 80 ℃, and the temperature of the hot water of producing with it can not satisfy manufacturing technique requirent.
The utility model content:
The purpose of the utility model is exactly the deficiency to prior art; And a kind of three grades of series connection high temperature heat pump units are provided; It can be fast is that dyeing waste water between 40-60 ℃ is warmed up to more than 90 ℃ clear water is disposable through heat exchange with temperature, to satisfy the demand of production technology to the high temperature clear water.
The technological solution of the utility model is following:
A kind of three grades of series connection high temperature heat pump units; Comprise heat pump; Each heat pump constitutes heat pump circuit by compressor, condenser, evaporimeter and electric expansion valve, and the condenser of three heat pumps connects through pipeline and is cascaded, and the evaporimeter of three heat pumps connects through pipeline and is cascaded; The clear water water inlet pipe connects the condenser water inlet of first heat pump, and the hot waste water water inlet pipe connects the evaporimeter of the 3rd heat pump; The condensator outlet of the 3rd heat pump connects the clear water outlet pipe, and the outlet of the evaporimeter of first heat pump connects the hot waste water outlet pipe.
Source pump hot waste water water intaking valve is installed on the said hot waste water water inlet pipe, the clear water water intaking valve is installed on the clear water water inlet pipe.
The beneficial effect of the utility model is:
Its heat pump through three grades of series connection three times is to clear water heating, the disposable high temperature clear water more than 90 ℃ that obtains accords with production technological requirement temperature.
Description of drawings:
Fig. 1 is the structural representation of the utility model
Among the figure: 1, hot waste water water inlet pipe; 2, clear water water inlet pipe; 3, heat pump; 31, first heat pump; 33, the 3rd heat pump; A1, compressor; A2, condenser; A3, evaporimeter; A4, electric expansion valve; 4, clear water outlet pipe; 1a, hot waste water water intaking valve; 2a, clear water water intaking valve; 5, hot waste water outlet pipe.
The specific embodiment:
Embodiment: see shown in Figure 1; A kind of three grades of series connection high temperature heat pump units; Comprise heat pump 3; Each heat pump 3 constitutes heat pump circuit by compressor A1, condenser A2, evaporimeter A3 and electric expansion valve A4, and the condenser A2 of three heat pumps 3 connects through pipeline and is cascaded, and the evaporimeter A3 of three heat pumps 3 connects through pipeline and is cascaded; Clear water water inlet pipe 2 connects the condenser A2 water inlet of first heat pump 31, and hot waste water water inlet pipe 1 connects the evaporimeter A3 of the 3rd heat pump 33; The condenser A2 outlet of the 3rd heat pump 33 connects clear water outlet pipe 4, and the outlet of the evaporimeter A3 of first heat pump 31 connects hot waste water outlet pipe 5.
Source pump hot waste water water intaking valve 1a is installed on the said hot waste water water inlet pipe 1, clear water water intaking valve 2a is installed on the clear water water inlet pipe 2.
Operation principle: generally only adopt two utmost points series connection heat pump in the prior art; Can't be warmed up to the dyeing waste water between 40-60 ℃ to more than 90 ℃ with clear water is disposable through heat exchange; The working medium (cold-producing medium) of its each heat pump all is the same simultaneously, and the COP of source pump is lower.The utility model; Utilize three heat pumps of three grades of series connection to form the high temperature heat pump unit; The working medium of each heat pump (cold-producing medium) is all inequality; Like this can be disposable be that dyeing waste water between 40-60 ℃ is warmed up to more than 90 ℃ clear water is disposable through heat exchange with temperature, to satisfy the demand of production technology to the high temperature clear water.
