Description

A kind of method of impelling generating or heat recovery or absorption system pump to economize energy
Technical field:
The present invention relates to a kind of method of saving generating or heat recovery or the used energy of absorption system pump machine, belong to the energy utilization technology field.
Background technique:
No matter be middle low-temperature generating system, residual neat recovering system, thermal power generation system at present, or absorption system, need carry out working medium with pump mostly and carry, consumed too much energy in the link of pumping working medium.Be commonly used for the ammonia that has of working medium, ammoniacal liquor, ammonia, chloromethanes, chloroethanes, ethanol, carbon sulfide, acetylene, carbon dioxide, freon, water, " seawater ", soft water, salt solution, lithium bromide, octanol, hydrogen, helium etc.
Summary of the invention:
The present invention places eminence by being transferred working medium, make it flow down the method for lower from eminence, solve generation current or heat recovery or absorption system working medium conveying process energy and consumed excessive problem, played the consumption of reduction pump energy, save the beneficial effect of the used energy of pump, make pump needn't consume too much energy and carry out the working medium conveying.The working medium elevated height, potential energy increases, and can overcome the system resistance acting, supply to vaporizer or equipment such as boiler or oxygen-eliminating device, energy that so just will not be too much is used for ordering about the pump transferring working medium, and is former in the too much that part of energy of the consumption of ordering about pump operation, saved.
Production process should be carried to working medium according to unit working conditions change and actual demand, guarantees that unit normally moves, and satisfies actual demand.Be example with the lithium-bromide absorption-type refrigerating machine, the solution circulating load is the key factor that influences unit performance.If it is excessive to enter the dilute solution amount of generator, then the heat major part of heating steam is used to improve the temperature of dilute solution in the generator, cause steam producing amount to reduce, refrigerating capacity descends, and the concentrated solution flow that leads to adsorber is increased, and temperature raises, and concentration reduces, cause the spray assimilation effect to worsen, absorptivity descends; If it is too small to enter the dilute solution amount of generator, cause the concentration difference of solution to increase, strong solution concentration is too high, and the danger of crystallization is arranged, thereby is necessary in the practical operation according to season, and various factorss such as refrigeration duty variation are rationally adjusted the solution circulating load, improve unit performance.Technical solution of the present invention, by working medium transferring regulator, pump are set, insert adsorber to the passage of generator, and adsorber is installed in the position that is not less than generator, a reasonable regulator solution circulating load is provided and has reduced the approach that the pump energy consumes, made unit have pump consuming little energy and the adjustable advantage of solution circulating load simultaneously.
