Abstract
The utility model discloses a heat pump energy saving system of printing and dyeing sewage heat, which comprises a printing and dyeing pool and a sewage pool. The heat pump energy saving system further comprises a heat pump closed circulating system formed by sequentially connecting a compressor, a condenser, an evaporator and an expansion valve. A supply water pipe of the printing and dyeing pool penetrates through a condensation heat exchanger of the condenser to be communicated with a supply water inlet of the printing and dyeing pool. A high temperature sewage discharge pipe of the printing and dyeing pool penetrates through an evaporation heat exchanger of the evaporator to be communicated with the sewage pool. Compared with the prior art, the heat pump energy saving system has the advantages of being capable of effectively utilizing heat energy of hot printing and dyeing sewage, improving heat efficiency of a printing and dyeing system, and reducing pollution of printing and dyeing sewage to the environment.
Description
Technical field
The utility model relates to a kind of dyeing and printing sewage heat heat pump energy-conserving system.
Background technology
At present, the dyeing and printing process of printing and dyeing mill need carry out in hot water, and this just needs to consume a large amount of heat energy and takes the heating process water, and the hot stamping after the use is stained water and not only is not used, and also can cause high temperature to pollute, and destroys environment.
The utility model content
The purpose of this utility model is: a kind of dyeing and printing sewage heat heat pump energy-conserving system is provided, can effectively utilizes hot stamping to stain the heat energy of water, improve the thermal efficiency of printing and dyeing system, reduce hot stamping and stain the pollution of water to environment.
For achieving the above object, the utility model can be taked following technical proposals:
A kind of dyeing and printing sewage heat of the utility model heat pump energy-conserving system comprises printing and dyeing pond and cesspool, also is provided with the heat pump closed circulation system that is connected and composed successively by compressor, condenser, evaporimeter and expansion valve; The make-up pipe in described printing and dyeing pond, the condensing heat exchanger in the condenser of flowing through is communicated with the make-up water inlet in printing and dyeing pond; The high temperature sewage comb in printing and dyeing pond, the evaporating heat exchanger in the evaporimeter of flowing through is communicated with cesspool.
Compared with prior art the beneficial effects of the utility model are: owing to be provided with the heat pump closed circulation system, water is stained in the hot stamping of coming out from the printing and dyeing pond, behind the evaporating heat exchanger by evaporimeter, the cold-producing medium working medium of evaporimeter will absorb hot stamping and stain the heat of water and deliver in the compressor, compressed machine is compressed into high temperature and high pressure steam, deliver in the condenser, by the condensing heat exchanger in the condenser will print and dye make-up water be heated into 80 the degree about hot water, cold-producing medium working medium becomes the low-temp low-pressure steam after emitting heat, behind expansion valve, be condensed into liquid, send into evaporimeter again.Printing and dyeing make-up water through the condenser heating flows in the printing and dyeing pond, and the sewage temperature after heat absorption reduces, and is discharged to cesspool.This structure of the present utility model can effectively utilize hot stamping to stain the heat energy of water, improves the thermal efficiency of printing and dyeing system, reduces hot stamping and stains the pollution of water to environment.
Description of drawings
Fig. 1 is a syndeton schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of dyeing and printing sewage heat of the utility model heat pump energy-conserving system comprises printing and dyeing pond 1, cesspool 6, and the heat pump closed circulation system that is connected and composed successively by compressor 5, condenser 3, evaporimeter 4 and expansion valve 2.The make-up pipe in described printing and dyeing pond 1, the condensing heat exchanger in the condenser 3 of flowing through is communicated with the make-up water inlet in printing and dyeing pond 1; The high temperature sewage comb in printing and dyeing pond 1, the evaporating heat exchanger in the evaporimeter 4 of flowing through is communicated with cesspool 6.
