Description
Technical field
The utility model relate to refrigeration and heating field, particularly a kind of utilize kitchen residual heat to drive absorption type refrigerating and heating system, belong to heat utilization field.
Background technology
The residual heat resources of China are very abundant, and the low grade residual heat resource of a large portion is not used effectively, and is discharged in air, causes significant damage to environment.How to make good use of residual heat resources, both can protection of the environment, again can saving resource.Along with the development of domestic cooking fuel, the application of coal gas, oil liquify gas, natural gas is increasingly extensive, especially large-scale dining room, restaurant, applies more general.How being used more fully by the waste heat of flue gas, can reduce again the discharge in greenhouse, be the problem that people study always simultaneously.
At present, existing multiple flue gas recovery device on market, the fume afterheat in kitchen can well use by this device, produces hot water and utilizes for people.But how to utilize the fume afterheat in kitchen to realize refrigeration and heating system, reducing energy consumption, is also problem demanding prompt solution simultaneously.
Summary of the invention
The purpose of this utility model is, utilize the fume afterheat in kitchen to drive absorption type refrigerating and heating system, both ensure that heat supply, can the cold that adsorption refrigeration system produces be used for fresh-keeping again, achieve the object of cold and heat combined supply, low product waste heat is obtained utilize more fully, improve the utilization rate of the energy.The utility model mainly comprises waste-heat recoverer (2), recuperation of heat pump (20), adsorbent bed, condenser (7), evaporimeter (11), incubator, cold water storage cistern, pipeline, valve, vacuum
Pump and pressure vacuum gauge, cold water storage cistern and incubator are connected with lower port with the upper port of adsorbent bed B with adsorbent bed A respectively; Waste-heat recoverer is communicated with the lower port of two adsorbent beds with recuperation of heat pump (20), and waste-heat recoverer is used for the fume afterheat in absorption boiler, and recuperation of heat pump (20) cools for reclaiming adsorbent bed the heat that the heat that discharges and absorption discharges.Meanwhile, the pipeline between two adsorbent beds is provided with valve (25), for regulating the flowing of the heat between adsorbent bed A and adsorbent bed B.
Operation logic of the present utility model adopts active carbon-methyl alcohol to be working medium pair for testing, when the kitchen in restaurant or dining room brings into operation, cooking fume is reclaimed by waste-heat recoverer, the heat reclaimed heats (valve closing between adsorbent bed B and waste-heat recoverer) adsorbent bed A, when reaching uniform temperature, start desorb.Open valve, under the condition of constant voltage, the continuous desorption of refrigeration working medium gas out, through condenser condenses, flow into evaporimeter, and adsorbent bed A continues to be heated; Meanwhile, in the casing at adsorbent bed B place, input cold water, adsorbent bed is constantly cooled, and after a period of time, reaches balance, carrys out refrigeration working medium after condenser, evaporimeter, absorbed, thus realize process of refrigerastion by adsorbent bed B from adsorbent bed A desorb.
After adsorbent bed B completes absorption, the hot water in the casing of adsorbent bed A place is put into the casing at adsorbent bed B place, meanwhile, open valve (22) and valve (27), its thermal source comes from two parts, and a part is the waste heat that boiler smoke produces; Another part is that recuperation of heat pump (20) exotherm of collecting and adsorbent bed cool the heat discharged.After hot water discharges, by the valve open between cold water storage cistern and adsorbent bed A place casing, put into cold water, ensuing process is identical with said process.In the process of circulation, in order to improve utilization rate of waste heat, between two adsorbent beds, be provided with recuperation of heat pump.When daytime restaurant and dining room kitchen run time, continuous circulation absorption type refrigerating can be realized; When night, kitchen was not run, process of refrigerastion suspends; Now, the hot water in the casing of adsorbent bed place can be put into incubator (3), for kitchen personnel.
