Description

A kind of oxygenation combustion-supporting rotary kiln
Technical field
The utility model relates to rotary kiln field of combustion technology, in particular to a kind of oxygenation combustion-supporting rotary kilns.
Background technique
Currently, during rotary kiln incineration hazardous waste, in the prevalence of design production capacity is not achieved, the main reason is that into Expect that moisture content is higher, it is relatively low with kiln hood, kiln end temperature wherein, is shown as during the burning process that separately there are also waste liquids when coordination, normally 850-900 DEG C of temperature kiln hood, 1050-1100 DEG C of kiln tail, 550-650 DEG C of actual temperature kiln hood, 800-900 DEG C of kiln tail, and CO Be easy it is exceeded, reason be exactly in combustion air oxygen content it is relatively low (for the material that burns), not enough oxygen Combustion-supporting, to ensure yield, kiln revolving speed again cannot be too slow, causes slag discharge amount increase, clinker ignition loss is high, and waste water is difficult to locate Many bad phenomenons such as reason occur, and dry and limited by safe and environment-friendly etc..
Utility model content
The technical problems to be solved in the utility model is to overcome the above technical problem, provides one kind and is intended to improve burning production Amount reduces clinker ignition loss, it is ensured that discharge exhaust gas qualified discharge, small investment, quick oxygenation combustion-supporting rotary kiln.
In order to solve the above technical problems, technical solution provided by the utility model is a kind of oxygenation combustion-supporting rotary kiln, it is special Sign is: including rotary kiln main body, blower and combustion-supporting mechanism, the blower is connected to rotary kiln main body by air hose, described Oxygen content monitor is equipped on air hose at rotary kiln main body, the combustion-supporting mechanism includes oxygen access tube, pressure regulator valve, oxygen Gas tank, air vent valve and cloth oxygen device, the oxygen access tube are connected to oxygen tank side by pressure regulator valve, and the oxygen tank is another Side is connected to cloth oxygen device by air vent valve, and the cloth oxygen device is mounted in air hose.
Preferably, the air hose is made of stainless steel material.
The utility model has the advantages that yield is burned in raising compared with prior art, reduces clinker ignition loss, it is ensured that row Put exhaust gas qualified discharge, it is small investment, quick, it avoids that contingency occurs.
Detailed description of the invention
Fig. 1 is a kind of oxygenation combustion-supporting rotary structure schematic diagram of the utility model.
It is as shown in the figure: 1, rotary kiln main body, 2, blower, 3, air hose, 4, oxygen content monitor, 5, oxygen access tube, 6, Pressure regulator valve, 7, oxygen tank, 8, air vent valve, 9, cloth oxygen device.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
In conjunction with attached drawing, a kind of oxygenation combustion-supporting rotary kiln, it is characterised in that: including rotary kiln main body 1, blower 2 and combustion-supporting machine Structure, the blower 2 are connected to rotary kiln main body 1 by air hose 3, are equipped with and contain at rotary kiln main body 1 on the air hose 3 Oxygen amount monitor 4, the combustion-supporting mechanism include oxygen access tube 5, pressure regulator valve 6, oxygen tank 7, air vent valve 8 and cloth oxygen device 9, The oxygen access tube 5 is connected to 7 side of oxygen tank by pressure regulator valve 6, and 7 other side of oxygen tank passes through air vent valve 8 It is connected to cloth oxygen device 9, the cloth oxygen device 9 is mounted in air hose 3.
The air hose 3 is made of stainless steel material.
The utility model pours into the pure oxygen of high concentration in combustion air, properly increases the oxygen content in combustion air, really It protects kiln temperature and reaches technique requirement.Oxygen is adjusted by pressure regulator valve into oxygen pressure (being higher than air-introduced machine pressure), and pressure is preferably small unsuitable Greatly, as long as ensuring to burn completely, oxygen is entered in oxygen tank, is adjusted oxygen air inflow by starting regulating valve, is passed through cloth Oxygen device generates whirlwind, and the air for entering oxygen and air-introduced machine is sufficiently mixed uniformly, is transported to rotary kiln as combustion-supporting use.And lead to It crosses oxygen monito and observes oxygen content at any time, in the case where ensuring condition of negative pressure, oxygen content as far as possible in raising air pipe makes to give up Object full combustion in rotary kiln, kiln temperature touch the mark requirement, and step up the revolving speed of whole system absorbing quantity and kiln.It is existing The air-introduced machine used is generally at 16-25 hertz, 10-15 hertz of kiln revolving speed, and 50 hertz maximum, the space of adjusting is plentiful, due to kiln Warm kiln speed all improves, and kiln temperature ensures burning quality, and kiln speed ensures burning yield, while ensuring economic benefit.
To ensure entirely to cure by oxygen therapy the safety of process, by kiln negative pressure and oxygen therapy pneumatic control valve interlocking, when kiln negative pressure is down to -5 When (can sets itself size) close oxygen therapy pneumatic control valve in time, avoid positive pressure from occurring making gas from the two-port of kiln spilling At the generation of the accidents such as poisoning, fire, explosion.Oxygen cathete uses stainless steel material (carbon steel is easy to happen kindling, explosion accident) Can also be chain by kiln temperature, oxygen content in air and pneumatic control valve, play duplicate protection.
The utility model is suitable for all rotary kiln incinerations.If causing calorific value uneven because material stirring is irregular and causing When of short duration positive pressure, can fill a check valve in kiln hood will be sent to incinerator with air-introduced machine again in one storage Xun of positive pressure escaping gas introducing It burns.
The utility model and embodiments thereof are described above, this description is no restricted, shown in attached drawing Be also one of the embodiments of the present invention, actual structure is not limited to this.All in all if this field Those of ordinary skill is enlightened by it, without deviating from the purpose of the present invention, not inventively design with The similar frame mode of the technical solution and embodiment, all should belong to the protection range of the utility model.
