Description

Organic waste gas treatment device

technical field

The utility model relates to an organic waste gas treatment device.

Background technique

In the current industrial production, various organic waste gases are produced, mainly including various hydrocarbons, alcohols, aldehydes, acids, ketones and amines. The current solutions to purify such waste gas are:

(1) Combustion and decomposition: high-temperature combustion can be divided into direct combustion method and catalytic combustion method, which are methods of decomposing pollutants through combustion. Catalytic combustion is a method that uses the action of a catalyst to decompose organic pollutants at a lower temperature. Because catalytic combustion can lower the decomposition temperature, it can greatly reduce operating costs. In the combustion method, heat exchangers are generally used in combination to exchange and reuse the heat energy of combustion. If heat storage is used for heat recovery, the more commonly used regenerative combustion (RTO) and regenerative catalytic combustion ( RCO) method, compared with the heat exchange method, this heat recovery method has the advantages of high heat recovery efficiency, and the RCO energy saving effect is more significant, but the RCO and RTO technologies are more complicated, and the initial investment in equipment is higher. the

(2) Biodegradation: The biodegradation method is to use the biological oxidation of microorganisms to decompose organic pollutants, and at the same time, microorganisms obtain the energy needed for survival. The more commonly used biological decomposition methods are biological scrubbers and biological filter beds. Others include MBR method, aerated sludge method and so on. Both the biological scrubber and the biological filter bed combine complex processes such as the absorption, adsorption and biochemical decomposition of pollutants, and capture the pollutants in the air by using water as the medium or adsorbent as the medium, and then use microorganisms to decompose them. break down. Since the life activities of microorganisms use water as the medium, for water-soluble and non-biologically toxic organic pollutants, biological methods can achieve better removal rates and stability, but for hydrophobic and toxic organic pollutants , the treatment efficiency of biological method is low. Biodegradation requires less external supplementary energy, so the operating cost of biodegradation is the lowest. For some hydrophilic organic pollutants, biodegradation is a better treatment process. However, due to the relatively slow rate of biodegradation, the biodegradation process generally requires a large space, and the problem of space occupation is more prominent in the case of large air volumes.

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model will be further described.

Examples for the above purposes have been illustrated pictorially.

Figure 1 is a schematic plan view of the utility model. As shown in Figure 1, the industrial organic waste gas is sent to the anti-fog flame arrester chamber 6 by the fan 1, and is filtered through a layer of anti-fog film 6a to remove relatively large granular colloids and dust in the organic waste gas. The organic waste gas enters the activated carbon adsorption chamber 10 through the exhaust pipe, and is adsorbed and filtered through the activated carbon layer 10a. The blower 8a discharges the air in the activated carbon adsorption chamber 10 after being adsorbed and filtered by the activated carbon layer 10a. In the activated carbon adsorption chamber 10, after the organic waste gas is filtered by the activated carbon layer 10a, the organic matter of the exhaust gas is adsorbed by the activated carbon layer 10a, so it is discharged The air that goes to meet the emission standards is a standard emission. During the foregoing process, the exhaust valves 7 and 8 are open, and the exhaust valves 4b and 3a are closed.

After the activated carbon suction layer 10a filters the waste gas for a certain period of time, when the concentration of the exhaust gas in the air discharged from the exhaust fan 8a reaches a certain value, the activated carbon suction layer 10a is saturated, and the exhaust valves 7, 8 and exhaust fans 1, 8a are closed. Open the heater 3 to work, then open the exhaust fan 3a to send the air on the top of the activated carbon layer to the heating chamber 3 for heating, then send it to the bottom of the activated carbon layer 10a by the ventilation duct, and the air blower 3a extracts air from the upper space of the activated carbon layer to make the activated carbon layer 10a The upper space creates a negative pressure on the lower space of the activated carbon layer 10a, so that the hot air in the lower space of the activated carbon layer 10a is pumped into the upper space of the activated carbon layer 10a through the activated carbon layer 10a, forming a circulating air flow, so that the upper and lower spaces of the activated carbon layer 10a The air is evenly heated. Heating the air in the activated carbon adsorption chamber 10 is to desorb the saturated activated carbon to desorb the organic waste gas. When the air temperature in the activated carbon adsorption chamber 10 reaches 100° C., the organic waste gas substances adsorbed on the activated carbon are completely desorbed. Open exhaust valve 4b now, start vacuum pump 4, the air that contains the desorbed organic matter in the active carbon adsorption chamber 10 is discharged in the condensation tank 9, and the temperature in the condensation tank 9 is kept at 0-- At 5°C, the waste gas containing organic substances desorbed in the activated carbon adsorption chamber 10 is sent to the condensation tank 9 for low-temperature condensation, and then changes from a gaseous state to a liquid state, and is directly discharged and collected from the condensation tank. Clean air is exhausted from the condensation tank 9 Port 9a discharges. When the vacuum pump 4 is pumping air from the activated carbon adsorption chamber 10, when the temperature of the air discharged from the exhaust port of the condensation tank 9 is greater than 5°C, the vacuum pump 4 automatically stops pumping, and when the temperature in the condensation tank 9 is low At 5°C, the vacuum pump automatically turns on to continue pumping.

When the vacuum gauge 4a on the vacuum pump 4 shows that the vacuum in the activated carbon adsorption chamber 10 reaches a certain value, the vacuum pump 4 stops working, the exhaust valve 4b is automatically closed, the heater 3b stops working, and the exhaust fan 3a is turned off. . The exhaust valves 7 and 8 are automatically opened, and the exhaust fans 1 and 8a are automatically turned on to work.

The activated carbon layer 10a in the activated carbon adsorption chamber 10 is a detachable part.

When the whole system is working normally, the above actions are repeated repeatedly to achieve the recovery and treatment of organic waste gas and organic matter.

As mentioned above, although the utility model has been described by examples, workers in the relevant technical fields cannot deviate from the scope of the application and the idea and field of the utility model to make modifications or deformations.
