Embodiment Construction

[0047] 1. Implementation mode of boiler flue gas water vapor condenser:

[0048] A. Manufacture of boiler flue gas water vapor condenser: first use a metal plate to make a cylinder or square cylinder (6) with both ends closed, and the outer diameter of the cross section of the cylinder (6) is slightly smaller than that of the flue (1) For the inner diameter size, open a number of circular holes with the same number on both ends of the cylinder (6) and align them one by one with a diameter slightly larger than the outer diameter of the metal pipe G (2), and then match the length of the corresponding number with the length of the cylinder (6) The same metal pipe G (2) extends into the cylinder body and is flush with the end face of the cylinder body (6), and a round hole is opened on the cylinder wall of the cylinder body (6) near one end surface and welded to the cooling medium inlet (5 ), a round hole is opened on the opposite side cylinder wall near the other end face and the...

Abstract

On the basis that causes and formation mechanisms of fog and haze in an atmosphere are analyzed detailedly, it is determined that the fog and haze produced in the atmosphere can by prevented or reduced only by reducing release of moisture and solid particles entering the atmosphere. The method comprises the steps that for flue gases released from burning of various oil fired and gas fired boilers and stoves, a flue gas moisture condenser is installed; for automobile exhaust, an automobile exhaust moisture condenser is installed; for water-bearing gas discharged by production equipment of industrial and commercial enterprises, a similar flue gas moisture condenser is installed; a large amount of moisture contained in the gases is mostly condensed into liquid water, partial solid particles adhered to the gases are cleaned by the liquid water, and the liquid water flows into the ground or sewers; for a low-pressure steam condensing mode of a thermal power plant, open water cooling is changed into closed water cooling or complete air cooling; watering on the city road surface is changed to washing on the road surface. The flue gas moisture condenser and the automobile exhaust moisture condenser are both made of metal materials, and effective heat dissipation and cooling can be achieved by allowing hot gas to pass through inner passages of the flue gas moisture condenser and the automobile exhaust moisture condenser.

Description

technical field [0001] The invention relates to a method and related equipment capable of preventing or reducing fog and haze from being produced in the atmosphere. Background technique [0002] At present, in many places in my country, especially in North China, Northeast China, and parts of Central China and East China, air pollution of fog and smog of varying severity often occurs in autumn, winter and early spring, especially in large and extra-large cities, which are more prone to severe pollution. Atmospheric fog and smog pollution. We know that fog is formed when the moisture content in the atmosphere or its local area reaches supersaturation at a certain temperature, resulting in a large number of liquid fine water droplets suspended in the air and staying over a certain area. Smog is formed by liquid fine water droplets It is formed by adding a large number of solid particles suspended in the air and staying over a certain area. Therefore, the constituent elements ...
