Problems solved by technology

[0003] However, there are generally two phenomena in practical applications. One is that the steam pressure supplied by the user is very low, below 0.05MPa.G. The other is that the user is not allowed to adjust the load change by adjusting the input heat, because most of the input heat sources are Process waste heat, if the adjustment input will cause changes in the user's process, the user needs to use a lithium bromide absorption refrigerator to consume all the waste heat generated by the process
Faced with these two phenomena, the unit cannot meet the user's control requirements when it is running at partial load

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] like figure 2 The shown single-effect lithium bromide absorption refrigerator involves evaporator 1, absorber 2, refrigerant pump 8, etc. A refrigerant regulating system is added to the unit, and the refrigerant regulating system regulates the flow from evaporator 1 to absorber 2. Refrigerant overflow, so as to adjust the load of the unit. The refrigerant adjustment system includes a refrigerant tank 11, a liquid level detection device 12, an overflow valve 13, a controller 14, and connecting pipelines and wiring. The refrigerant is sprayed in the evaporator 1 The pipe leads to a bypass pipeline 10, the bypass pipeline 10 is installed with a relief valve 13, the bypass pipeline port is connected to the absorber 2, the evaporator is installed and connected to the refrigerant tank 11, and the refrigerant tank is provided with a liquid Level detection device 12...

Abstract

The invention relates to the technical field of the lithium bromide absorption-type machine unit control. A load adjusting method relates to a single / double effect lithium bromide absorption-type refrigerating machine; and the machine unit is added with a refrigerant adjusting system which adjusts the overflow quantity of the refrigerant from an evaporator to an absorber, thus adjusting the load of the machine unit. The method has simple structure, is additionally provided with a bypass pipeline and an overflow valve in the traditional machine unit, controls in real time by a control loop, conducts the adjustment of the overflow quantity of the refrigerant according to the size of the load, adjusts the load by adjusting the overflow quantity of the refrigerant, and does not adjust the input heat by a control valve, therefore, when being loaded partially, the machine unit not only can stably run to guarantee the refrigerating requirements of a user, but also can consume the waste heat generated by a technique completely by the machine unit, and has no influence on the operation of the technique of the user. Simultaneously, the control loop formed by liquid level detection and the controller protects a refrigerant pump and prevents the cavitation erosion phenomenon occurred on the refrigerant pump and has wide application scope.

Description

technical field [0001] The invention belongs to the technical field of lithium bromide absorption type unit control, and relates to a load regulation method of a single / double-effect lithium bromide absorption type refrigerator. Background technique [0002] Previous single-effect lithium bromide absorption refrigeration units such as figure 1 As shown, it is widely used in the recovery and refrigeration of waste heat (low temperature water below 100°C, low pressure steam below 0.2MPa.G, low temperature flue gas). Its working principle is: the cold water in the evaporator 1 is cooled by the low-temperature refrigerant water from the condenser 3 after decompression and throttling, and the refrigerant water absorbs the heat of the cold water and evaporates into refrigerant steam, which enters the absorber 2 and is absorbed by the concentrated solution , into a dilute solution. The dilute solution in the absorber 2 is sent to the heat exchanger 5 and heat recovery device 6 (w...
