An output end of the circulation water pump (9) is connected with the check valve (8), and the other end of the check valve (8) is connected with the sampling water cooling device (5) by the pipeline. The utility model has the advantages of high cooling efficiency, small size, convenient installation and low cost. After the components are installed in a concentrated way, the utility model can be conveniently operated and managed. The utility model can particularly control the cooling temperature.
Description
Technical field
The utility model relates to a kind of refrigeration mode combined cycle cooling device that is used for fuel-burning power plant water and steam sampling system.
Background technology
The used water and steam sampling cooling device in fuel-burning power plant must be used the demineralized water cooling device, and demineralized water cooling device of the prior art mainly is made up of water tank, water pump, heat interchanger and valve, its water tank is bulky, install inconvenient, and taken very big fabricating yard, also to be equipped with frame, equipment manufacturing cost height for it, in addition, it also causes the cooling effectiveness of whole sampler to reduce.
Summary of the invention
The purpose of this utility model provides the refrigeration mode combined cycle cooling device that a kind of cooling effectiveness height, volume are little, be convenient to install, be convenient to control temperature.
The technical scheme that realizes above-mentioned purpose is: a kind of refrigeration mode combined cycle cooling device, comprise the demineralized water cooling device, sample water pre-cooler, sampler and sample water-cooling apparatus, the sample water-cooling apparatus is by sampling cooler, isolation valve and cooling sea water regulating valve are formed, the demineralized water cooling device is by compressor, condenser, throttling valve, evaporator, cooling water tank and isolation valve, water circulating pump and non-return valve are formed, one end of compressor is connected with condenser, the other end is connected with evaporator, the other end of condenser is connected with throttling valve, the other end of throttling valve is connected with evaporator, evaporator is positioned at cooling water tank, the water inlet of cooling water tank is connected with pre-cold water storage cistern in the sample water pre-cooler by pipeline, the water delivering orifice of cooling water tank is connected with the input end of water circulating pump with isolation valve by pipeline, the recirculated water delivery side of pump is connected with non-return valve, and the other end of non-return valve is connected with the sample water-cooling apparatus by pipeline.
After adopting technique scheme, the demineralized water cooling device is by compressor, condenser, throttling valve, evaporator, cooling water tank and isolation valve, water circulating pump and non-return valve, thereby saved the demineralized water water tank, and frame, electric control part is graded, do not need the industrial colling inlet tube and outlet tube yet, the volume of cooling device is dwindled greatly, can save very big fabricating yard, not only easy for installation, and reduced cost, and saved cost, be convenient to operational management after installing concentratedly, simultaneously, also improved the cooling effectiveness of whole sampling cooling device.In addition, the cooling device of being made up of compressor, condenser and evaporator etc. comes cooling and desalting water, also is convenient to control the temperature of sample water, guarantees cooling effect.
