Abstract
The utility model relates to a device used to remove the high-concentration interval nitrogen oxides from the industrial off-gas, comprising absorbing cover, fan, air-draining pipe, air-inlet pipe, absorption tower, air-outlet pipe, waste-liquid pool, absorbent pool, serum circulation pump and serum under-water pump. The invention is characterized in that an air-sending bag is set in the air-inlet of the tower and the air-outlet of air-sending bag is guaranteed to be in the absorbent by the level-controller. The off-gas equally enters the absorption tower through the air-sending bag and the atomized absorbent sprays inside the tower. After a sufficient reaction, the off-gas is discharged from the air-outlet. Its advantages lie in less costs and higher off-gas disposal rate and less space requirement.
Description
Technical field
The utility model relates to environmental protection equipment, refers in particular to a kind of device that removes industrial waste gas middle and high concentration intermittence nitrogen oxide.
Background technology
At present, the processing of nitrogen oxide industrial waste gas is a global problem, is thrown into the SO in the atmosphere
2And NO
XIt is the one of the main reasons that forms " acid rain " and " acid mist ".Wherein, nitrogen oxide and hydrocarbons are in conjunction with forming photochemical fog, and they have caused great harm to the human health and the natural ecological balance! Processing for the nitrogen oxide routine has water absorption method, sour absorption process, alkaline solution absorption process, oxidation-reduction method etc., and these processing methods are not high for the treatment effeciency of high concentration nitrous oxides exhaust gas, and can not solve the problem of high concentration intermittence well.
Summary of the invention
In order to address the above problem, improve the treatment effeciency of high concentration nitrous oxides exhaust gas, the purpose of this utility model provides a kind of device that removes high concentration intermittence nitrogen oxide, it has introduced the atomizing spray technology on the basis of existing technology, improved treatment effeciency, and designed the bag of getting angry, solved the problem of intermittence substantially.The realization the technical solution of the utility model is:
It comprises blast pipe, air inlet pipe, absorption tower, escape pipe, waste liquid pool, absorbent pond, the recycle slurry liquid pump, the diving slush pump is characterized in that the air inlet in tower is installed the bag of getting angry, and guarantee in absorption liquid by liquid level control the gas outlet of the bag of getting angry, waste gas is equably from getting angry bag in absorption liquid enters tower, cat head is provided with many row's shower nozzles, and through the vaporific absorbent that the shower nozzle atomizing spray goes out, waste gas and absorbent fully react the back and discharge from exhaust outlet.
The utility model is exactly traditional water absorption method, alkali absorb method secondary to be absorbed unite two into one, and finishes in an absorption tower; Introduce the technology of atomizing spray simultaneously, the control concentration of absorbing prolongs the reaction time, increases the reaction contact-making surface; When high concentration intermittence nitrous oxides exhaust gas enters the absorption tower, settled the bag of getting angry, high concentration intermittence nitrous oxides exhaust gas can be discharged uniformly.The utility model can remove high concentration intermittence nitrogen oxide efficiently, and can reach national waste gas emission standard.
The utility model has the advantages that cost is low, exhaust-gas treatment efficient height, site requirements is not high.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation
As shown in the figure, number in the figure is represented respectively: 1. 6. escape pipes, 7. waste liquid pools, 8. absorbent ponds, air-suction cover 2. ventilating fans 3. blast pipes, 4. air inlet pipe, 5. absorption towers, 9. recycle slurry liquid pumps, 10. diving slush pumps 11. are got angry and are wrapped 12. shower nozzles.
The specific embodiment
As shown in Figure 1, the structure of this device is:
By air-suction cover (1) and ventilating fan (2) forms getter device pass through blast pipe (3), air inlet pipe (4) links to each other with absorption tower (5), air inlet in tower is installed the bag (11) of getting angry, guarantee in absorption liquid by liquid level control the get angry gas outlet of bag (11), waste gas is equably from getting angry bag (11) in absorption liquid enters tower, be the vaporific absorbent that atomizing spray goes out in the tower, waste gas fully reacts the back discharges from blast pipe (6), and cat head is two row's shower nozzles (12).The absorbent that sprays is by circulation oar liquid pump (9) circulated sprinkling utilization once more.When the liquid level in absorption tower (5) is too high, a part can be entered in the waste liquid pool (7).Constantly new absorbent in absorbent pond (8) is fed in the absorption tower (5) by diving slush pump (10).
Claims (1)
1. remove the device of high concentration intermittence nitrogen oxide, it comprises: blast pipe (3), air inlet pipe (4), absorption tower (5), escape pipe (6), waste liquid pool (7), absorbent pond (8), recycle slurry liquid pump (9), diving slush pump (10), it is characterized in that the air inlet in tower installs the bag (11) of getting angry, the gas outlet of the bag (11) of getting angry is arranged in absorption liquid by liquid level control, arranges shower nozzles (12) cat head is provided with more.
