Embodiment 1

[0031] Example 1: Combining figure 1 and figure 2 and image 3 , Figure 4 Utilize the waste gas condensation recovery system of condensing unit, it is characterized in that, recovery system comprises refrigerating unit 2, and the cold air that refrigerating unit 2 comes out can carry out heat exchange with water in circulating water tank 1; The chilled water inlet pipe, the chilled water outlet pipe and the chilled water inlet pipe lead into the water-air heat exchanger 6, and the water-air heat exchanger 6 protrudes from the pipeline to connect the gas-liquid separator 8; the chilled water outlet pipe and the chilled water inlet pipe connect Entering into the water-air heat exchanger 6 enables the frozen water to cool down the water-air heat exchanger 6 and allow as much organic matter as possible to dissolve in the water during the process. The substantive technical effects played by the technical solution here and its realization process are as follows: the environment...

Embodiment 2

[0032] Embodiment 2: As a further improved solution or a side-by-side solution or an optional independent solution, the pipeline connecting the gas-liquid separator 8 and the water-gas heat exchanger 6 is the inlet pipe 7 .

Embodiment 3

[0033] Embodiment 3: As a further improved scheme or a side-by-side scheme or an optional independent scheme, the water-gas heat exchanger 6 includes an inlet pipeline for entering hot oil and gas containing water; the water-gas heat exchanger 6 also includes a water inlet and Outlet. The substantive technical effect and the realization process of the technical solution here are as follows: the water inlet and the water outlet can enter water, and can absorb hot oil and gas containing water.

Abstract

The invention relates to the field of refrigeration, in particular to a waste gas condensation recovery system utilizing a condensing unit and an environment-friendly treatment method. The method comprises the following steps that a refrigeration technology is utilized, the temperature of chilled water is lowered, the amount of gas blended into water is increased, heat exchange is conducted on refrigerating fluid and oil gas again, and harmful gas in tail gas can be blended into low-temperature liquid so as to be simply separated out; water vapor contained in the tail gas is cooled and condensed in the gas-liquid separator to form liquid which can be cleanly discharged; and separated gas, namely light oil gas, is introduced into the combustion furnace through the gas-liquid separator to be incinerated, so that zero emission is realized.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a waste gas condensation recovery system and an environmental protection treatment method using a condensing unit. Background technique [0002] To meet the requirements of environmental protection, in the production of petroleum refining and chemical industry, a large amount of hot oil gas will be produced that pollutes the air. In line with the requirements of human health and the environment, the tail gas must be separated and treated in order to be green, safe and clean. The harmful hot exhaust gas is washed by two stages of water, and most of the exhaust gas is dissolved in water and separated, but there is still a small amount of harmful gas that cannot be separated after the two processes. Contents of the invention [0003] Purpose of the invention: In order to provide a waste gas condensation recovery system using condensing units with better effect, see the multiple substanti...
