Abstract
The invention discloses a heat pump with vacuum efficacy, comprising a steam-driven self-control implement instrument, a low-temperature steam regulating valve, a main bent injection pipe, a mixing pipe, a shell and a low-temperature steam inlet, wherein the steam-driven self-control implement instrument is fixed with the low-temperature steam regulating valve and is arranged at the top end of the shell; the main bent injection pipe and the low-temperature steam inlet are respectively arranged at the both sides of the shell; and the mixing pipe is arranged at the bottom end of the shell. The heat pump fully utilizes the pressure energy and the heat energy of the high-pressure steam or the superheated steam.
Description
Technical field
The present invention relates to a kind of heat pump, particularly a kind of heat pump with vacuum efficacy.
Background technique
Temperature is lower than water vapor often generation in industrial production of 100 ℃, because temperature is lower, it is very big to recycle difficulty, and particularly when vacuum evaporation (concentrating), the steam of generation is only about 80 ℃.Although temperature has only 80 ℃, its energy that has (heat content) is 631.1kcal/kg, and 119 ℃ of steam enthalpy 646.9kcal/kg only differ 15.8kcal/kg.Therefore reclaiming this part energy, is very important to saving energy and reduce the cost, and also is the effective way that evaporation (concentrating) device reduces cost.
Usually the pressure of boiler steam supply is at 0.8MPa, and if to use power plant's steam be the very big superheated vapor of heat, before use, all pass through decompression or spray cooling and reaches customer requirements, so a large amount of heat dissipation is at reduction valve with heat in the water that sprays into.
As shown in Figure 1, existing vacuum evaporator comprises vaporizer 1 and vacuum system 2, is evaporating with vaporizer 1 in (concentrating) process, in order to reduce the boiling point that is concentrated material, all adopts vacuum system 2 to achieve the goal.Like this, when reducing boiling point (energy-conservation), increased the power consumption of vacuum system again.
Summary of the invention
Technical problem to be solved by this invention provides a kind of heat pump with vacuum efficacy, and it allows the pressure energy and the heat energy of high pressure steam or superheated vapor be fully utilized.
For solveing the technical problem, the invention provides a kind of heat pump with vacuum efficacy, it is characterized in that, it comprises steam-operating self-control implementation instrument, Low Temperature Steam modulating valve, main injection bend pipe, mixing tube, shell and Low Temperature Steam inlet, steam-operating self-control implementation instrument and Low Temperature Steam modulating valve are fixed together, steam-operating self-control implementation instrument is on the top of shell, and main injection bend pipe and Low Temperature Steam inlet lay respectively at the both sides of shell, and mixing tube is positioned at the bottom of shell.
Positive progressive effect of the present invention is: the present invention had both reclaimed the heat content of the steam of low temperature, again can all or part of replacement vacuum system, allow high pressure steam or superheated vapor pressure can and heat energy be fully utilized.
Description of drawings
Fig. 1 is the work schematic representation of existing vacuum evaporator.
Fig. 2 has the structural representation of the heat pump of vacuum efficacy for the present invention.
Fig. 3 has the working principle schematic representation of the heat pump of vacuum efficacy for the present invention.
Embodiment
Lift a preferred embodiment below, and come the clearer the present invention that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 2, the heat pump that the present invention has vacuum efficacy comprises steam-operating self-control implementation instrument 121, Low Temperature Steam modulating valve 122, main injection bend pipe 123, mixing tube 124, shell 125 and Low Temperature Steam inlet 126, steam-operating self-control implementation instrument 121 is fixed together with Low Temperature Steam modulating valve 122, steam-operating self-control implementation instrument 121 is on the top of shell 125, main injection bend pipe 123 and Low Temperature Steam inlet 126 lay respectively at the both sides of shell 125, and mixing tube 124 is positioned at the bottom of shell 125.
After superheated vapor or the higher steam of pressure enter heat pump by main injection bend pipe 123, because Venturi principle, this high speed steam flow produces pumping action, with Low Temperature Steam by the Low Temperature Steam 126 suction heat pumps that enter the mouth, after in mixing tube 124, fully mixing, leave heat pump, enter on user's the pipeline pressure transducer is housed, when pressure surpasses customer requirements, steam-operating self-control implementation instrument 121 will be moved, Low Temperature Steam modulating valve 122 is moved downward, strengthen the Low Temperature Steam amount that enters heat pump, make and leave heat pump, entering the pipeline vapor pressure descends, otherwise Low Temperature Steam modulating valve 122 reduces the Low Temperature Steam amount that enters heat pump owing to the domination of steam-operating self-control implementation instrument 121 moves upward then.
The heat pump that the present invention has a vacuum efficacy utilizes this part energy of overheated or overpressure of steam, 80 ℃ of steam that pumping unit or whole vaporizer come out, guaranteed that vaporizer works under vacuum state, both reclaimed 80 ℃ of steam energies of vaporizer, and no longer allowed the heat energy of high steam of pressure or superheated vapor do meaningless consumption and waste again.
As shown in Figure 3, high pressure steam or hot superheated vapor enter the heat pump 12 with vacuum efficacy through the main injection bend pipe, and Low Temperature Steam (as 80 ℃ of steam) inlet is carried out automatic control through pneumatil control valve according to the pressure of outlet steam of the heat pump with vacuum efficacy and regulated and enter.Because entering, Venturi effect main injection bend pipe produces high speed steam flow formation negative pressure, therefore Low Temperature Steam is inhaled into, and makes vaporizer 11 obtain vacuum, and the steam of two kinds of grades enters vaporizer after section is fully mixed, reach the vapor pressure of production requirement, use for process units.Whole device no longer adopts common water spray or reduction valve, when satisfying the system vacuum requirement Low Temperature Steam energy is all recycled.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these mode of executions.Therefore, protection scope of the present invention is limited by appended claims.
