Technical field

The utility model relates to a kind of energy-saving and cost-reducing technical field, particularly a kind of dying setting machine flue gas energy-saving and purifying complete equipments.

Background technology

Along with more and more faster increasingly high with industrialization degree of the step of nearest decades of whole world industrialization progress, for the demand of traditional fossil fuel with consume also sharply increase, on the one hand, aggravated the exhausted speed of non-renewable fossil fuel; On the other hand, the greenhouse gases that the use of fossil fuel is discharged also make the global environmental pollution aggravation, and ecological environment goes from bad to worse.These problems have caused the concern of global national governments and enterprise, and power-saving technology and renewable energy technologies have obtained the attention of more and more countries and enterprise.Therefore, under current energy-intensive overall background, all trades and professions are tried one's best invariably and are carried out energy-saving and cost-reducing activity by every means, improve the industrial model of original high energy consumption.And this reform and opening-up in thirties years of China when economy obtains significant achievements, has also been paid the heavy cost of severe environmental pollution; So governments at all levels of current both the central and local governments are all in transition of carrying forward vigorously economic structure and adjustment; Pursue and save energy and reduce the cost, the industry pattern of protection environment.

The dyeing that present patent application is related; Since closely bound up with people's life, also be the traditional larger economic industry of China, when the dress that makes people beautifies; Also consumed a large amount of energy; Simultaneously because dyeing when industry size constantly enlarges and advances, has also polluted a large amount of precious water resource and atmosphere.

In dyeing, dying setting machine is indispensable production equipment.Dyeing machine can discharge a large amount of waste gas when operation; Its exhaust gas discharged not only contains volume of smoke; Also have polyphenyl type organic, printing and dyeing assistant, the multiple composition of wet goods simultaneously, every general discharged particle 150-250mg/m3 of setting machine, oil smoke 40-80mg/m3.The oil that is discharged, cigarette, dirt all have very big harm to human body health and environment.

The utility model content

To the problems of the prior art; The utility model proposes a kind of flue gas energy-saving and purifying complete equipments; Be used for the supporting a large amount of setting machines that use of dyeing that are applied in, be intended to reduce the smoke evacuation of setting machine, and can the preheating cold air; The smoke evacuation of purification setting machine, and reclaim the grease/tar in the flue gas.

For reaching the purpose of the utility model, the flue gas energy-saving and purifying complete equipments of the utility model comprise filter, air preheater and purifying column; Be provided with the multiple tracks silk screen along the flue gas flow direction in the wherein said filter, can filter out big portion grease and velveteen; Said air preheater is to be provided with the heat exchanger with heat exchanger tube, utilizes hot flue gas heating cold air; Said purifying column is provided with cooling water pipe, and waste collector.

Preferably, in said filter, timing water injector is housed, drenches screen pack, prevent to be deposited in velveteen on the filter screen because of electrostatic fire.

Preferred again, the silk screen of said filter adopts the steel silk screen.

Preferred again, for strengthening heat exchange, heat exchanger tube adopts the finned tube of generally popular use, can reduce the profile and the weight of air preheater like this, for the user practices thrift cost.

The utility model utilize described flue gas energy-saving and purifying complete equipments carry out with setting machine supporting the heat energy that is used for carrying out flue gas is utilized again and the flow process of waste collection following:

The flue gas that comes from setting machine is at first through filter, and the silk screen filter of filter is fallen most grease and velveteen; Flue gas is behind filter; Get into air preheater, cold air carries out heat exchange from the air inlet entering of air preheater through heat exchanger tube and carries out the flue-gas temperature cooling, and the gas after heating flows out the confession setting machine from outlet to be used; With the increase heat energy utilization, and the energy consumption that can save setting machine; Flue gas gets into purifying column through behind the air preheater, and this moment, flue gas still had than higher temperature, through inner cooling water pipe and waste collector; On one side the temperature with flue gas further reduces, and it is discharged from the top of purifying column with lower temperature (being generally below 60 ℃), and harmful substances such as contained aldehyde, ketone, hydrocarbon, aliphatic acid, alcohol, ester, lactone, heterocyclic compound, aromatic compound in the setting machine discharged flue gas; Through the inner waste collector of supercooling and purifying column and moisture, cotton-wool etc. together, condensed by major part; Again through after the road separating technology; With water, cotton-wool, organic matter further separates; Organic matter in the isolated end product is taken on the market and is sold, and obtains economic interests; The water of heating also can utilize again.

The beneficial effect of the utility model is; Described flue gas energy-saving and purifying complete equipments; When cooperating setting machine to use, can effectively carry out the utilization again of flue gas heat, effectively reclaim contained harmful substance in the flue gas simultaneously; Not only can reduce the energy consumption of setting machine, also reduce fume emission pollution on the environment problem; And can turn waste into wealth, the harmful substance of discharging is collected and utilization again, obtain the certain economic interests, save production cost.
