Abstract
The invention relates to a high-temperature waste gas afterheat recycling and peculiar smell treating method. When an open fire detector does not detect open fire, an automatic fireproof valve is opened, high-temperature waste gas passes through the automatic fireproof valve via a flue, enters a heat exchanger and heats cold water in the heat exchanger into hot water, the hot water is delivered in a hot water tank for later use, waste gas discharged from the heat exchanger enters an electric field generator, waste oil in the waste gas is removed and collected in a waste oil tank by using an electrostatic oil removal technology, and then the treated waste gas is discharged through a fan. According to the high-temperature waste gas afterheat recycling and peculiar smell treating equipment and the high-temperature waste gas afterheat recycling and peculiar smell treating method, the open fire detector is arranged in the flue, when open fire is detected, the automatic fireproof valve is closed immediately through a controller so as to prevent fire from spreading, and simultaneously, a spraying fire extinguishing device is started to extinguish the fire. Besides, heat in the waste gas is recycled through the heat exchanger, the waste oil in the waste gas is separated from the waste gas and recycled through the electric field generator, so that the waste gas can be discharged directly, and environment friendliness is realized.
Description
Technical field
The present invention relates to the environmental protection field, the Apparatus and method for that especially a kind of high-temp waste gas waste heat recovery and peculiar smell are handled.
Background technology
Industry low-carbon (LC) production inhabitation green environment, energy-saving and emission-reduction are maximum problems of current society, are to carry out the requirement that development in science and technology is seen; Also being to build resource-conserving and environmentally friendly social task, is the problem about the sustainable development of socio-economy overall situation, and the 17th Session of the General Assembly or the National People's Congress that are party are all environmental protection; Clean energy resource; Cleaner production has been put on the agenda, and China will accelerate low-carbon (LC) production, technical research and popularization; And encourage enterprise's increasing low-carbon (LC) production technology transformation and technological innovation to push, enhance the capability of independent innovation.
Zhejiang Province government, Jiaxing City government strengthens energy savings work suggestion conscientiously successively about low-carbon (LC) production, and Tongxiang municipal government is also energy savings; Reduce discharging as adjusting economic structure, change the breach and the important means of growth pattern, municipal government has put into effect a series of about strengthening energy conservation and implementation suggestion, as the important goal of macro adjustments and controls; Mobilize the strength of the whole society, carry out cleaner production and energy-saving and emission-reduction work in a down-to-earth manner, confirm the restrictive index of actual energy-saving and emission-reduction; Promote economy development both fast and sound, this project is complied with the Party Central Committee, the call of State Council and governments at all levels; Give full play to us and be engaged in that energy technology is used and the exploitation advantage, it is master's national top 100 (county) city with the light textile industry that the Tongxiang is one, and there is family surplus the printing and dyeing enterprise 50 whole city; Printing and dyeing enterprise need carry out destarch to machining object in process of production, boiling-off, bleaching and the refining of mercerising after washing; After processing, need drying and shaping, typing just needs to use forming machine; Flue can be discharged a large amount of high-temp waste gas and harmful substance during typing, and surrounding enviroment have been caused very big influence, is directly connected to the healthy of common people.Caused great amount of heat energy to waste simultaneously, gone back atmosphere pollution, mentioned today of agenda simultaneously in energy-saving and cost-reducing and environmental protection, we have reason these energy that is wasted is recycled again.
The general recovery and the peculiar smell treating apparatus, single have only heat reclamation device, do not have the peculiar smell treating apparatus; Another kind is single to have only the water spray to abandon the flavor device, but does not have heat reclamation device.So effect is all undesirable, especially, forming machine all is a hyperthermia drying, fiber. the dyestuff grease is easy to catch fire, in case catch fire, consequence is with hardly imaginable, and economic loss and social influence are huge, directly influence the people life property safety, thereby this problem is badly in need of solving.
From the test operation situation, its ruuning situation is very convenient to the city, and is quick; Recuperation of heat and to abandon the peculiar smell effect also fairly obvious, economic benefit is also very considerable, is the our province cleaner production; A highly effective approach has been opened up in low-carbon (LC) production, to promoting the rural and urban industry cleaner production, the low-carbon (LC) life; Economic construction, economic development is of great practical significance.

Described automatic fire prevention valve 1, it mainly comprises valve body 10, valve body 10 is a loop configuration; In valve body 10, be provided with three valve plates 11, valve plate 11 splicing backs are consistent with the hollow shape of valve body 10 inside, and three valve plates 11 all are connected with valve body 10 through rotating shaft; Between three valve plates 11, connect through interlinked mechanism 12, on the valve plate 11 of centre, be provided with extension spring 14, extension spring 14 is connected with valve body 10; Be provided with controller 13 in valve body 10 outsides; Controller 13 is connected with the rotating shaft of middle valve plate 11, and said to be the naked light survey meter be connected with controller 13 on the automatic fire prevention valve 1, on valve body 10, is provided with a temperature sensor 15.
The method that high-temp waste gas waste heat recovery and peculiar smell are handled; When the naked light survey meter did not detect naked light, automatic fire prevention valve 1 was opened, and high-temp waste gas passes through automatic fire prevention valve 1 through flue; Get into heat exchanger 5 through maintenance fire resisting damper 3 and filter screen 4 backs; High-temp waste gas is heated to hot water to the cold water in the heat exchanger 5, and hot water is sent in the boiler 7 subsequent use, and the waste gas that heat exchanger 5 comes out gets into electric field generation device 6; Utilize the static degreasing technique that the waste oil in the waste gas is removed and is collected in the dirty oil tank 8, the waste gas after will handling is then discharged through blower fan 9.
Through measuring: waste gas has been separated the total alkynes measured value of methane from the air-introduced machine mouth, divides three times, is respectively: 0.380MG/M3,0.817MG/M3,0.676MG/M3.
Through measuring, 85 ℃ of flue temperatures need 18 ℃ of the temperature of heat exchange clear water, and the temperature of exchange back clear water is 63 ℃, per hour uses about 15-20T.
Waste oil reclaims: after the electric field oil smoke separates, calculated by 24 hours, can reach about 200KG.
Economic benefit:
The theoretical quantity of steam of practicing thrift calculates as follows:
Computing formula: Q * Δ t * 1000 ÷ 600000
Q: discharge
Δ t: the temperature difference, 63 ℃-18 ℃=45 ℃
1000: the heat that 1 ℃ of water of every intensification needs is 1000 kilocalories
600000:1 ton steam contains heat
With 5000 cubic metres of/hour waste gas discharge capacities is example, can practice thrift steam: Q * Δ t * 1000 ÷ 600000=5 * 45 * 1000 ÷ 600000=0.375 tons/hour
That is to say that press per hour 5000 cubic metres of/hour discharge capacitys, clear water reaches 63 ℃ from 18 ℃ through after the heat exchange; It can practice thrift 0.375 ton/hour of steam; With 150 yuan of calculations of present steam price per ton, can economize on the use of funds 56.25 yuan, waste oil reclaims by printed fabrics different; Isolated oil does not wait yet, approximately about 7KG/ hour.
Economize on the use of funds the whole year like following table:
