Problems solved by technology

[0003] There are also a lot of researches in China trying to utilize them as resources, but in the existing technologies, some are purely for the recovery of organic solvents, without considering the pollution caused by the process to the environment, and some have uncertain safety factors in the process of processing, and some In the process of processing, mucous membrane wrapping bubbles will be formed, so that the organic solvent and water cannot be completely separated, and the recovery effect is not ideal

Embodiment 1

[0046] like figure 1 As shown, a waste paint slag reduction and drying equipment includes: a solid-liquid separation system 1 , a liquid-liquid separator 2 , a gas-liquid conversion system 3 , a cooling silo 4 , and a waste gas treatment system 5 .

[0047] Put the waste paint slag into the solid-liquid separation system 1, dry it under negative pressure, extract the water vapor, sewage, and organic solvent generated during the drying process, and realize solid-liquid separation; dry the waste paint slag after a certain period of time sent to the cooling silo 4 for cooling treatment; the extracted sewage and organic solvent enter the liquid-liquid separator 2 for separation, the organic solvent can be recycled after being stored in the storage box, and the sewage enters the sewage treatment system for treatment and discharge after reaching the standard; The exhausted gas enters the gas-liquid conversion system 3 for treatment, the separated waste gas is discharged up to the st...

Embodiment 2

[0099] like Figure 18 As shown, the present invention provides a kind of waste paint slag reduction drying process, comprising the following steps:

[0100] In the first step, the waste paint slag is put into the drying host in the solid-liquid separation system 1 for drying, and the drying host is set as a negative pressure environment;

[0101] In the second step, the water vapor and organic solvent generated in the solid-liquid separation system 1 are cooled by the refrigerating unit 34 to realize gas-liquid conversion;

[0102] In the third step, the water vapor and organic solvent are pumped out with a vacuum pump, and the gas enters the exhaust gas treatment system 5, and is discharged after the treatment reaches the standard, and the organic solvent is recycled;

[0103] In the fourth step, the liquid obtained from the solid-liquid separation system 1 and the gas-liquid conversion system 2 is sewage and organic solvent, and the organic solvent is recycled through the ...

Embodiment 3

[0107] The difference between this embodiment and the above-mentioned embodiment is that the thermometer of a device for reducing and drying waste paint slag can use a glass rod thermometer or a platinum thermal resistance sheet. Because the movement of gas molecules is very inactive under vacuum conditions, ordinary thermometers cannot display the real temperature of waste paint residue, but can only indicate the relative temperature of waste paint residue. The position indicated by the mercury column of the left-point thermometer does not decrease with the decrease of temperature, but remains and indicates the highest point ever reached; platinum thermal resistance elements usually use industrial mica platinum resistance as the temperature measurement sensor, and the temperature transmitter , regulators and display instruments are used together to form a process control system, which can be used to directly measure or control the temperature of liquid, steam and gas media and...

Abstract

The invention discloses a gas-liquid conversion system and equipment with the same. The gas-liquid conversion system comprises a condensing device; the condensing device is connected with a freezing unit used for providing required condensed water for the condensing device, and the other end of the condensing device is connected with a buffer device used for buffering liquid which is formed aftergas is condensed; the buffer device is connected with a first vacuum device; and the other end of the first vacuum device is connected with a water tank device, and the first vacuum device utilizes water in the water tank device to convert the gas which is not converted timely into liquid through water circulation. Organic solvents can be prevented from adhering and flow to a buffer tank through the gravity, a vacuum pump device pumps cooled air to a water tank through water circulation, parts of the residual organic solvents are intercepted in the water tank, and thus secondary pollution is prevented.

Description

technical field [0001] The invention relates to the technical field of sludge drying, in particular to a gas-liquid conversion system and equipment with the system. Background technique [0002] With the development of industries such as automobiles and home appliances, there are more and more industrial wastes. How to effectively deal with these industrial wastes has become an urgent matter for various manufacturers, and the cost of occupying the earth's resources is also getting higher and higher, especially waste The proper disposal of paint slag and the reduction and utilization of waste paint slag are imminent. [0003] There are also a lot of researches in China trying to utilize them as resources, but in the existing technologies, some are purely for the recovery of organic solvents, without considering the pollution caused by the process to the environment, and some have uncertain safety factors in the process of processing, and some In the process of processing, mu...
