Device for guiding airflow to impact liquid level in tangential direction for forming moisture-containing airflow

Abstract

The invention relates to a device structure used in the fields of liquefied natural gas heating gasification, natural gas heating, dust removal, central air-conditioning systems and the like. A device for guiding airflows to impact the liquid level in a tangential direction for forming moisture-containing airflows is characterized in that a conical spraying opening (4) communicated with a vertical downward airflow air inlet pipe (2) is arranged in a container (3), liquid (6) is arranged under the spraying opening (4), the lower part of an airflow swirl water element (5) in a reverse umbrella shape is soaked in the liquid (6), an airflow outlet (1) is led out on a passage formed between the inner wall of the container (3) and the outer walls of the air inlet pipe (2) and the spraying opening (4), the middle of the airflow swirl water element (5) is an upwards projected pointed top (5a) and then is an arc-shaped curve surface (5c) formed by being upwards bended a little after firstly going downwards to an edge by a curve line shape extending from the pointed top to the edge, and the horizontal projection of the outer ring of the airflow swirl water element (5) has the same shape as the horizontal cross section of the spraying opening (4) and is in a circular shape or a polygon shape. The invention has the advantages of simple structure and no movable component, is applicable to various kinds of strengthened heat transfer, has the functions of dust removal, humidifying purification and the like, and improves the heat efficiency and the dust removing efficiency.

Description

technical field [0001] The invention is a device structure used in the fields of liquefied natural gas heating and gasification, natural gas heating, dust removal, and centralized air-conditioning systems, and specifically relates to heating by guiding high-speed airflow tangentially impacting the liquid surface to form a wet vortex airflow , dust removal, humidification and purification functions. Background technique [0002] Energy conservation and emission reduction is a top priority in today's world, and our country also attaches great importance to it as a basic national policy. [0003] 1. In terms of energy saving, improving the thermal efficiency of various heat exchange devices is one of the key technologies. Liquefied natural gas heating gasifier and natural gas heating furnace are widely used heating devices in the natural gas industry. Today, natural gas is increasingly valued as a clean energy source. Improving the thermal efficiency of such devices is an urge...

Problems solved by technology

The dust removal device is a device for dust removal treatment of exhaust gas discharged from various operations such as boilers, medicine copying machines, casting workshops, brick kilns, wood processing, central air conditioning, range hoods, etc. Commonly used dust removal devices include cyclone dust collectors and bag dust collectors. These dust removal devices have their own characteristics, advantages and disadvantages, and are also suitable for some occasions. However, due to the different shapes and sizes of dust particles, such as: in wood processing The generated dust such as small pieces of wood, shavings, and wood chips has a large difference in mass and weight. For this mixed dust, only using a cyclone separator or a bag filter cannot solve the dust removal problem well, and the dust removal efficiency is low; another example: When removing dust from the flue gas produced by boilers and brick kilns, due to the high temperature of the flue gas, the general dust collector is not suitable, and the water film dust removal method is usually used, but due to the large resistance of the water film dust removal device, the induced draft fan The power of the motor increases, and the power consumption is large. The dust removal efficiency of the dust removal device is low and the energy consumption is large, which affects energy saving.
