Method used

Embodiment nine: as further improved scheme or side-by-side scheme or optional independent scheme, utilize the environmental protection processing method of condensing unit, it is characterized in that, utilize recovery system as above, comprise following method: utilize refrigeration Technology, the temperature of the chilled water is lowered, the amount of gas incorporated into the water is increased, and the refrigerant is exchanged with the oil and gas again, and the harmful gas in the tail gas can be integrated into the low-temperature liquid, so that it can be easily separated; the water vapor contained in the tail gas is separated in the gas-liquid separation After being condensed and condensed into liquid in the device, it can be cleaned and discharged; the separated gas, namely light oil and gas, is led to the combustion furnace for incineration through the gas-liquid separator to achieve zero emissions.

Embodiment one: in conjunction with Fig. 1 and Fig. 2 and Fig. 3, Fig. 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 be in circulating water tank 1 Neutralize the water for heat exchange; the circulating water tank 1 protrudes from the chilled water outlet pipe and the chilled water inlet pipe, and 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 extends out The pipeline is connected to the gas-liquid separator 8; the chilled water outlet pipe and the chilled water inlet pipe lead into the water-gas heat exchanger 6 so that the frozen water can cool the water-gas heat exchanger 6 and allow as much organic matter as possible to dissolve in the process In the water. The substantive technical effects played by the technical solution here and its realization process ...

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.

Example Embodiment

[0031] Example 1: Combination figure 1 with figure 2 with image 3 , Figure 4 The exhaust gas condensation recovery system utilizing the condensed unit, wherein the recovery system includes a refrigeration unit 2, and the air conditioner from the refrigeration unit 2 can be heat exchange in the circulating water tank 1; the circulating water tank 1 extends the freezing water outlet tube and The frozen water inlet tube, the frozen water outlet pipe and the frozen water inlet pipe are introduced into the water gas heat exchanger 6, and the water gas heat exchanger 6 projects the pipe connection to the gas-liquid separator 8; the frozen water outlet pipe and the frozen water import pipe The inlet gas heat exchanger 6 allows the frozen water to cool down the water gas heat exchanger 6 and allow the tried organic matter to dissolve as much as possible in the water. The technical effects of the technical solution and its implementation process are as follows: the environmental protection method using the condenser set, characterized in that the recovery system as described above is comprised of the following method: using refrigeration technology, frozen The water temperature is lowered, and the amount of gas incorporating water increases, the freezing liquid is again exchanged with the oil and gas, and the harmful gas in the exhaust gas can be integrated into the low temperature liquid, which is simply separated; the water vapor contained in the exhaust gas is in the gas-liquid separator. After cold condensation, it is clean and eliminated; the separated gas is passed by the gas-liquid separator to the combustion furnace incineration, and zero emissions.

Example Embodiment

[0032] Example 2: As a further improved scheme or a parallel scheme or an alternative independent scheme, the pipeliner connected to the air-liquid separator 8 and the water gas heat exchanger 6 is the intake pipe 7.

Example Embodiment

[0033] Embodiment 3: As a further improved scheme or a selection or selection of independent scheme, the water gas heat exchanger 6 includes an inlet pipe for water-impregnating a hydrothermal air; water-air heat exchangers also contain inlet and Outlet. The substantive technical effects of the technical solutions and their implementation processes are as follows: water inlet and outlets can be intake, and water-containing hot oil can be absorbed.
