The structure and the working principle of the existing second-class absorption heat pump are as follows: referring to fig. 1, the evaporator 4 and the generator 1 use low-grade waste heat as a driving heat source, when the lithium bromide dilute solution in the absorber 3 flows through the heat exchanger 5, heat exchange is performed with the lithium bromide concentrated solution in the heat exchanger, the temperature of the dilute solution is reduced, the dilute solution enters the generator 1, the dilute solution is heated to boiling by hot materials under negative pressure to generate refrigerant steam, and the dilute solution is concentrated into concentrated solution. The concentrated solution is driven by the solution pump 6, flows through the heat exchanger 5, and then rises in temperature to enter the absorber 3, absorbs the refrigerant vapor from the evaporator 4, and emits a large amount of heat to heat the copper pipe. The refrigerant vapor generated by the generator 1 under negative pressure enters the condenser 2, and is condensed into low-temperature refrigerant by the cooling water flowing in the condenser. The refrigerant enters the evaporator 4 through the refrigerant pump 7, absorbs the heat of the hot material to evaporate, and turns into refrigerant vapor to enter the absorber 3. The refrigerant vapor is absorbed by the concentrated solution in the absorber 1 to become a dilute solution to release heat, the hot water copper pipe in the absorber is heated, and new circulation is continued to continuously generate heat to heat the hot water.

the absorber 30 is provided with a first heat exchange tube 31 therein, the first heat exchange tube 31 having a hot water inlet and a hot water/steam outlet; two second heat exchange tubes A11 and B12 are arranged in the generator 10, and each second heat exchange tube is provided with a heat source inlet and a heat source outlet; the condenser 20 is internally provided with a third heat exchange tube 21, and the third heat exchange tube 21 is provided with a cooling water inlet and a cooling water outlet; the evaporator 40 is provided with two fourth heat exchange tubes, a fourth heat exchange tube A41 and a fourth heat exchange tube B42, each of which has a heat source inlet and a heat source outlet.
In this embodiment, two heat exchange tubes are disposed in the generator 10 and the evaporator 40, and in other embodiments, 1 or more heat exchange tubes may be disposed in different numbers in the generator and the evaporator. The specific number can be flexibly adjusted according to the use condition.
In this embodiment, the two heat exchange tubes in the generator 10 and the evaporator 40 are arranged in the same manner, that is, may be arranged in parallel left and right, or in parallel up and down, or in staggered manner.
As shown in fig. 3, two second heat exchange tubes a11 and B12 in the generator 10 are arranged left and right, the middle is separated by a partition plate 13, a first spray pipe 201 is arranged above the second heat exchange tube a11, a second spray pipe 202 is arranged above the second heat exchange tube B12, and the first spray pipe 201 and the second spray pipe 202 are respectively connected with the second solution pipe 2 through branch pipes. The lower end of the second heat exchange tube A11 extends out of the front side of the generator to form a first heat source inlet 111, and the upper end extends out of the front side of the generator to form a first heat source outlet 112; the lower end of the second heat exchange tube B12 extends out of the rear side of the generator to form a second heat source inlet 121, and the upper end extends out of the rear side of the generator to form a second heat source outlet 122.
When the evaporator or the generator cylinder is arranged left and right, the evaporator or the generator cylinder is divided into two independent spaces by the partition plate, so that the vaporization space can be reduced and the heat exchange efficiency can be increased when one device heat source is independently used; the conversion of low-yield and high-yield steam can also be performed.
As shown in fig. 4, two second heat exchange tubes a11 and B12 in the generator 10 are arranged up and down, and share a shower pipe 201; the lower end of the upper second heat exchange tube A11 extends out of the left side of the generator to form a first heat source inlet 111, and the upper end extends out of the left side of the generator to form a first heat source outlet 112; the lower end of the second heat exchange tube B12 on the lower side extends out of the right side of the generator to form a second heat source inlet 121, and the upper end extends out of the right side of the generator to form a second heat source outlet 122.

In the use of the present utility model,
taking the evaporator/generator with two heat exchange tubes as an example, the first waste heat generated by the production device, namely the heat source 1, is firstly like the fourth heat exchange tube B42 of the evaporator 40, then enters the second heat exchange tube B12 of the generator 10, the second waste heat generated by the production device, namely the heat source 2, is firstly like the fourth heat exchange tube A41 of the evaporator 40, then enters the second heat exchange tube A11 of the generator 10, the heat source 1 is the main heat source, the heat source 2 is the auxiliary heat source, and under normal conditions, the main heat source runs at full load, and the auxiliary heat source properly reduces the flow. When the physical properties of the main heat source change, especially when the released heat is reduced, the auxiliary heat source can be increased to supplement, so that the heat pump unit can achieve the design load operation; and, when a high yield of steam is required, the load of the subsidiary heat source can be appropriately increased through calculation to produce more heat sources.
Taking the three heat exchange tubes in the evaporator/generator as an example for explanation, under normal conditions, one or two waste heat flows into the heat exchange, when one waste heat flows out of the production device,
can enter a third heat exchange tube for heat exchange, and can also produce more steam. The design can be realized through the on-off state of the corresponding switch valve.
Of course, the evaporator and the generator can also use different heat sources, namely, the waste heat generated by the production device only enters the evaporator and does not enter the generator, and the waste heat is directly discharged after heat exchange in the evaporator; or the waste heat only enters the generator, does not enter the evaporator, and is directly discharged after heat exchange in the generator.
In a word, the utility model can switch the working state of the heat pump according to the requirements of the users for the steam yield in different stages, so that the heat pump is in a high-yield or normal state to meet the requirements for the steam yield.
The foregoing is merely a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model and remain within the scope of the utility model.
