Liquid distribution mixing device for heat exchanger

Abstract

The invention provides a liquid distribution mixing device for a heat exchanger. A liquid inlet pipe of the liquid distribution mixing device is mounted at the upper end of a supporting body and extends into the supporting body, liquid accommodating grooves are formed in the supporting body, and the liquid inlet pipe extends into the corresponding liquid accommodating groove; diffusion pipes comprise connecting pipes, diffusion pipe bodies and butterfly valve combined pieces; the connecting pipes and the butterfly valve combined pieces as well as the diffusion pipe bodies and the butterfly valve combined pieces are connected through flanges; pressure water inlets and gas inlets are formed in the connecting pipes; the diffusion pipe bodies comprise gas-water combined chambers and solution diffusion chambers; the gas-water combined chambers are connected with the butterfly valve combined pieces; the outlet ends of the solution diffusion chambers are pressure mixing gas water accommodating outlets; and spraying nozzles are formed between the gas-water combined chambers and the solution diffusion chambers. The liquid distribution mixing device is reasonable in structure and good in mixing uniformity, and the heat exchanging effect is improved.

Description

technical field [0001] The invention relates to a liquid distribution and mixing device for a heat exchanger, which belongs to the technical field of heat exchangers. Background technique [0002] Heat exchangers are usually composed of partitions, fins, seals, and deflectors. Fins, deflectors and seals are placed between two adjacent partitions to form an interlayer, which is called a channel. Such interlayers are stacked in different ways according to the liquid, and brazed into a whole to form a plate bundle. The plate bundle is a plate. The core of the finned heat exchanger, also known as the core. Generally, the hot fluid in the plate-fin heat exchanger flows from top to bottom, while the cold liquid flows from bottom to top. When the hot liquid is liquid phase or gas-liquid two-phase and the flow rate is low, it is easy to form a bias flow when the liquid phase enters the core from the heat exchanger head, so that the liquid cannot be evenly distributed to the entire...
