Description
Technical Field
The invention relates to the technical field of air conditioner waste gas treatment, in particular to an air conditioner two-device degreasing and VOCs waste gas treatment device.
Background
According to the forty-fifth item of the atmospheric pollution prevention and treatment law of the people's republic of China, production and service activities for generating waste gas containing volatile organic compounds are carried out in a closed space or equipment, and pollution prevention and treatment facilities are installed and used according to regulations; cannot be sealed, and measures should be taken to reduce exhaust emission. Reaches the secondary standard of Table 2 in the national Integrated emission Standard of atmospheric pollutants (GB16297-1996), the standard of Table 2 in the emission Standard of malodorous pollutants (GB14554-1993), and the other industrial standards of Table 1 in the emission control Standard of volatile organic compounds (DB 13/2322-2016) of industrial enterprises. Major environmental factor limit criteria: the particle is less than 120mg/m 3; the total diameter of the non-methane is less than 80mg/m 3; benzene is less than 1mg/m 3; toluene and xylene < 40mg/m 3. Odor concentration < 2000 (dimensionless).
The two devices (copper tube aluminum foil finned heat exchanger, widely used in the air conditioner, ice machine, dehumidification, oil cooling, water cooling and other fields), widely used in the processing of M607C, M108A or equivalent volatile oil products, used in the fin and copper tube processing of lubrication and cooling, after the processing, must remove otherwise will influence the final hydrophilic heat exchange performance of the product and hydrolysis corrosion copper tube quality hidden danger.
The traditional cleaning equipment for removing the relevant lubricating oil by adopting trichloroethylene medicament has strong toxicity, can cause serious damage to nerves, livers, skins and the like of people, seriously pollutes the environment and is gradually forbidden to use.
The M607C and M108A are in a good combination or oil products with the same volatility, have low boiling points (two concentrated volatilization temperature points of about 120 ℃ and 150 ℃) and high burning explosion points (the flash point (closed cup method) is more than 52 ℃), are easy to volatilize, and have relatively good safety performance. The conventional method is that a gas heating drying furnace accelerates the volatilization speed of volatile oil on the surface of a workpiece through high temperature, and takes away air with high concentration of the volatile oil on the surface of the workpiece through high-speed air blown out from an air port; through a large amount of circulating air, the air with high volatile oil concentration is diluted to accelerate the volatilization speed of the oil. The exhaust device is arranged at the high position of the volatile oil concentration, so that the volatile oil concentration in the furnace body is not too high to cause danger. However, the traditional drying furnace has no proper treatment scheme for waste gas, and a large amount of VOCs are remained in discharged substances.

The working principle of heat storage and standing degradation of VOCs is as follows: and in the time T1, the electromagnetic control valve S18 is opened, the waste gas collected by the waste gas collecting fan 7 enters the heat storage degradation chamber 17 through a waste gas recovery air pipe, the temperature of the waste gas is increased under the action of the heat accumulator, and the waste gas is stood in the heat storage degradation chamber 17 for degradation. Discharging waste gas subjected to standing degradation treatment in the previous period, allowing the waste gas to enter a combustion chamber 15 through a heat exchange decomposition pipeline 18, oxidizing and decomposing organic matters in the waste gas into carbon dioxide (CO2), water (H2O) and other pollution-free substances under a high-temperature condition (more than or equal to 760 ℃), allowing the reacted high-temperature flue gas to enter a heat storage degradation chamber 17, storing most of heat in a heat accumulator (a special corrugated heat-conducting ceramic sheet), and then exhausting the heat via a chimney 16; at the same time, the thermal storage degradation chamber 17 is in a thermal degradation state. There are three states for each incinerator: the heat is transferred to the waste gas to heat the waste gas, the heat of the high-temperature waste gas is transferred to a heat accumulator (a special corrugated heat-conducting ceramic plate), the waste gas is degraded by heat preservation, and the waste gas alternately operates according to the sequence.
And in the time T2, the electromagnetic control valve S4 is opened, the waste gas collected by the waste gas collecting fan 7 enters the heat storage degradation chamber 17 through a waste gas recovery air pipe, the temperature of the waste gas is increased under the action of the heat accumulator, and the waste gas is stood in the heat storage degradation chamber 17 for degradation. Discharging waste gas subjected to standing degradation treatment in the previous period, allowing the waste gas to enter a combustion chamber 15 through a heat exchange decomposition pipeline 18, oxidizing and decomposing organic matters in the waste gas into carbon dioxide (CO2), water (H2O) and other pollution-free substances under a high-temperature condition (more than or equal to 760 ℃), allowing the reacted high-temperature flue gas to enter a heat storage degradation chamber 17, storing most of heat in a heat accumulator (a special corrugated heat-conducting ceramic sheet), and then exhausting the heat via a chimney 16; at the same time, the thermal storage degradation chamber 17 is in a thermal degradation state. There are three states for each incinerator: the heat is transferred to the waste gas to heat the waste gas, the heat of the high-temperature waste gas is transferred to a heat accumulator (a special corrugated heat-conducting ceramic plate), the waste gas is degraded by heat preservation, and the waste gas alternately operates according to the sequence.
And in the time T3, the electromagnetic control valve S2 is opened, the waste gas collected by the waste gas collecting fan 7 enters the heat storage degradation chamber 17 through a waste gas recovery air pipe, the temperature of the waste gas is increased under the action of the heat accumulator, and the waste gas is stood in the heat storage degradation chamber 17 for degradation. Discharging waste gas subjected to standing degradation treatment in the previous period, allowing the waste gas to enter a combustion chamber 15 through a heat exchange decomposition pipeline 18, oxidizing and decomposing organic matters in the waste gas into carbon dioxide (CO2), water (H2O) and other pollution-free substances under a high-temperature condition (more than or equal to 760 ℃), allowing the reacted high-temperature flue gas to enter a heat storage degradation chamber 17, storing most of heat in a heat accumulator (a special corrugated heat-conducting ceramic sheet), and then exhausting the heat via a chimney 16; at the same time, the thermal storage degradation chamber 17 is in a thermal degradation state.

T4-6 and its subsequent repeats T1-3. And alternately run in this order.
A chimney 16: the degraded and purified gas is discharged to the atmosphere through a chimney 16.
The safety guarantee scheme is as follows: in order to prevent the heat accumulation degradation chambers 17 and the heat exchange decomposition pipeline 18 from backfiring due to the fact that dust particles are ignited or pressure fluctuation relates to the pipeline, a flame arrester is installed at an inlet to ensure that high-temperature waste gas cannot flow back into the waste gas collecting pipe.
When the concentration of the waste gas collected by the waste gas collecting fan 7 is higher but less than 25% of the explosion lower limit, the waste gas collecting fan 7 is installed with an on-line gas concentration detector at the position of the enough distance of the collecting front end, and the waste gas is safely treated. The response time is about 3-5 seconds. When the exhaust gas concentration is detected to be high, the electromagnetic control valves S18-S6 are all automatically opened to carry out bypass dilution; if the concentration of the continuously scrapped gas is high, the online of the combustion chamber 15, the heat storage degradation chamber 17 and the production line is cut off.
