Description

Technical Field

[0001] This utility model relates to the field of lithium bromide absorption refrigeration technology, specifically to a liquid distribution device. Background Technology

[0002] Existing lithium bromide absorption chillers suffer from uneven liquid distribution within the generator, especially when non-condensable gases are present. This leads to severe liquid impact and splashing, which can reduce the utilization rate of the heat exchange surface and decrease system efficiency. Traditional liquid separation structures typically employ bottom openings, which can cause severe liquid disturbance within the shower tray and hinder gas-liquid separation, resulting in operational instability. Therefore, there is an urgent need for a structural device that can achieve effective gas-liquid separation and uniform liquid distribution to improve heat exchange efficiency and system reliability. Summary of the Invention

[0003] The purpose of this invention is to provide a gas-liquid separation and liquid distribution device for lithium bromide units, in order to solve the problems of uneven solution distribution, poor separation effect of non-condensable gases and solution splashing in existing devices, and to achieve efficient, stable gas-liquid separation and uniform liquid distribution.

[0004] To achieve the above objectives, the present invention includes an inlet pipe 1, a liquid-blocking groove 2, a liquid-distributing box 3, a liquid-distributing pipe 4, a spray plate 5, a spray plate outlet hole 51, and a heat exchange tube 6. The inlet pipe 1 is connected to the liquid-distributing box 3 for introducing the solution into the unit. The liquid-distributing box 3 has liquid collection and distribution holes on both sides, which are connected to several liquid-distributing pipes 4 to achieve uniform solution distribution. The liquid-distributing box 3 and the liquid-distributing pipes 4 have outlet holes at the top to facilitate the upward separation of non-condensable gases and reduce solution splashing. The liquid-blocking groove 2 is located above the liquid-distributing box 3 and the liquid-distributing pipes 4 for collecting splashed solution and gaseous substances. The spray plate 5 is located below the liquid distribution assembly composed of the inlet pipe 1, the liquid-distributing box 3, and the liquid-distributing pipes 4, and the spray plate outlet hole 51 is located directly above the heat exchange tube 6 to ensure that the solution is evenly dripped onto the heat exchange tube 6.

[0005] This device has the following significant advantages: Improved solution distribution uniformity: The solution flow distribution is consistent through the graded distribution of the liquid distribution box and the liquid distribution pipe; High-efficiency gas-liquid separation: The top liquid outlet design promotes the natural separation of non-condensable gases and solutions; Anti-splashing and anti-disturbance: The liquid baffle collects splashed solution, avoiding disturbance to the solution in the shower tray and preventing turbulent solution flow; Simple and reliable structure: The components are compactly arranged and the maintenance cost is low.

[0011] Exemplary embodiments of the present invention are described in detail below with reference to the accompanying drawings to enable those skilled in the art to readily implement them; for clarity, parts irrelevant to the description have been omitted.

[0012] A preferred embodiment of this utility model is a gas-liquid separation liquid distribution device for lithium bromide generator units, suitable for lithium bromide absorption generator units. The device includes an inlet pipe 1, a liquid-blocking groove 2, a liquid distribution box 3, a liquid distribution pipe 4, a spray plate 5, a spray plate outlet 51, and a heat exchange pipe 6. The inlet pipe 1 is connected to the liquid distribution box 3, and the solution in the unit enters the liquid distribution box 3 through the inlet pipe 1. The liquid distribution box 3 has collection and distribution holes on both sides, connected to several liquid distribution pipes 4, allowing the solution to be evenly distributed to the liquid distribution pipes 4 through the liquid distribution box 3. The liquid distribution box 3 and the liquid distribution pipes 4 have outlet holes at the top, unlike traditional bottom-type devices. Compared to the previous design, the top outlet hole helps separate non-condensable gases from the solution, preventing high-pressure solution from splashing directly onto the shower tray 5, effectively reducing solution disturbance and splashing. A baffle trough 2 is provided above the liquid distribution box 3 and the liquid distribution pipe 4. Non-condensable gases and water vapor flashing due to heat brought in by the solution are splashed onto the baffle trough 2 through the outlet hole. The baffle trough 2 collects the solution and drips it into the shower tray 5. The shower tray 5 is provided with several shower tray outlet holes 51, which are located directly above the heat exchange tube 6. The solution drips evenly onto the heat exchange tube 6 through the shower tray outlet holes 51, achieving efficient heat exchange.

[0013] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, modifications, equivalent substitutions or improvements can be made according to actual needs. All changes within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
