Device for solving systematic problem of gas flooding of absorption-type unit

Abstract

The invention provides a device for solving the systematic problem of gas flooding of an absorption-type unit. The device comprises a flow guide pipe, wherein the glow guide pipe comprises a prep-storing device, a flow rate adjusting component and a connecting pipe; one end of the flow guide pipe is connected with the rectifier of the absorption-type unit, and the other end is connected with a lowpressure side pipe; the low pressure side pipe is used for feeding a solution in a generator into an absorber; and the pre-storing device is used for pre-storing a distillation fluid flowing out of the rectifier.

Description

technical field [0001] The invention relates to the field of absorption heat pump units, in particular to a device for solving the systematic problem of the absorption unit flushing the tower. Background technique [0002] Due to the increase of electricity bills, the shortage of electricity during the peak period of electricity consumption and the increasing awareness of global environmental protection, the use of heat energy from pollution-free working fluids to drive ammonia water-absorption air source heat pump units to meet heating and domestic hot water has once again attracted people's attention. Due to the wide range of operating conditions of the unit, high ambient temperature and low water temperature operation are prone to tower flushing due to the large amount of occurrence, resulting in a sharp decline in unit performance and failure to work normally. Traditional technical solutions can solve this problem, but the size of the unit is increased by about 300mm, wh...

Problems solved by technology

The principle of solving tower punching phenomenon in the prior art is shown in Figure 3 Shown: Ammonia vapor enters the rectifier 102 from the generator 101, and after being purified by the rectifier 102, the liquid ammonia solution returns to the water tank of the generator by the height difference from point A to point D, and the rectification liquid is removed by this method When the external ambient temperature is high and the generator produces a large amount, the distillate cannot be removed in time and effectively, resulting in the phenomenon of tower flushing, which seriously affects the efficiency of the unit

In order to solve the tower flushing problem, the traditional method needs to raise the height of the rectifier by at least 300mm, so that the A-D height difference increases, so as to achieve the effect of eliminating the distillate. This solution will not only increase the production cost, but also occupy a lot of space, which is not conducive to the unit Installation and transportation
