Embodiment 1

[0044] Such as figure 1As shown, an intensive high-efficiency plume treatment and purification system of the present invention includes a first heat exchanger 4, a middle header 6, a second heat exchanger 7, a gas collector and dehydrator 8, a condensed water recovery mechanism 9, a first The fan and the second fan 10, the first heat exchanger 4 communicates with the second heat exchanger 7 through the middle header 6, the second heat exchanger 7 communicates with the gas collector and dehydrator 8, and the pipe side inlet of the second heat exchanger 7 communicates with The first fan obtains cold air, and the flue gas in the second heat exchanger 7 can exchange heat with the cold air, and the condensed water recovery mechanism 9 is installed at the bottom of the gas collector and dehydrator 8 and the fan; the outlet on the shell side of the second heat exchanger 7 communicates The inlet of the second fan 10, the outlet of the second fan 10 is connected to the shell-side inlet...

Embodiment 2

[0061] Embodiment 2 discloses an intensive smoke plume treatment and purification method, the flue gas flows through the tube body of the first heat exchanger 4 and the shell of the second heat exchanger 7, and the original flue gas passes through the first heat exchanger 4 After the preliminary cooling, the temperature is further lowered in the second heat exchanger 7 .

[0062] The flue gas cooled by the first heat exchanger 4 and the second heat exchanger 7 is discharged through the tail gas discharge chimney 5 after heat exchange with the high-temperature raw flue gas in the first heat exchanger 4 .

[0063] Specifically, the intensive smoke plume treatment and purification method specifically includes the following steps:

[0064] 1) The flue gas passes through the pipe fittings of the first heat exchanger 4, and the exhaust gas passes through the shell of the first heat exchanger 4, so as to ensure that the temperature inside the pipe fittings is maintained at a relative...

Abstract

The invention discloses an intensive smoke plume treatment and purification system and method, comprising a first heat exchanger and a second heat exchanger, the first heat exchanger communicates with the second heat exchanger; the first heat exchanger includes a pipe body And the shell wrapped outside the tube, the tube is used for flue gas circulation, the shell is used for exhaust gas circulation, the temperature of the tube is higher than the temperature of the shell; the second heat exchanger includes the tube and the shell wrapped outside the tube body, the tube body is used for cold air circulation, the shell is used for flue gas circulation, and the temperature of the shell is higher than the temperature of the tube body; the shell outlet of the first heat exchanger is used for the discharge of flue gas. The present invention can realize the comprehensive control of smoke plume through reasonable equipment design and ingenious system design, especially for renovation projects, it can effectively solve the problems of difficulty in implementing smoke plume control and poor control effect by taking advantage of extremely small land occupation.

Description

technical field [0001] The invention relates to the field of waste treatment, in particular to an intensive smoke plume treatment and purification system and method. Background technique [0002] During the smoke exhaust process of various production units in the iron and steel industry, the phenomenon of "white feathers" of high-humidity flue gas often appears. The formation of smog in the air has caused a lot of waste of water vapor. With the vigorous promotion of domestic ultra-clean emissions, the dust content of the air has been effectively controlled, but the large-scale smog weather has not been suppressed and alleviated. Plume emission is one of the important factors that generate smog, so eliminating plume has become a necessary link to solve smog, so it is particularly important to provide an intensive, efficient and feasible smoke plume control plan. [0003] The inventor believes that to control the smoke plume phenomenon, it is necessary to comprehensively con...
