Weary wind nail alkane concentration is lower than the industrial tail gas that industries such as 1% mine ventilation gas and chemical industry, papermaking, wastewater treatment contain fuel gas.It is the discharging in atmosphere directly, on the one hand, has aggravated atmosphere pollution, has caused greenhouse effect; Caused the serious waste of limited non-renewable resources on the other hand, only annual its low heat valve of gas that discharges from coal mine methane stream is equivalent to the low heat valve of 3,370 ten thousand tons of standard coals.
Therefore, carry out weary wind and utilize technical research,, improve atmosphere quality, have very important significance for effectively utilizing existing resource and reducing greenhouse gas emission; Can promote simultaneously China's response environment and change and contractual capacity, improve the environmental protection equipment technical level, promote the Environmental Protection in China industry development.Weary wind comprehensive utilization technique starts from the fifties in last century four abroad, and China then starts from the seventies and eighties in last century.At present, core technology is still grasped in developed country.
Weary wind use device is divided into from principle both at home and abroad: hot reverse-flow oxidation unit and catalytic oxidizing equipment, and by oxidation unit, make the gas generation oxidation reaction in the weary wind produce heat energy with calorific value, make waste gas not useless! But no matter be any oxidation unit, all need reliable intake and exhaust exchange inverse circulation systerm,, guarantee the reaction temperature in central reaction district and the heat of exporting by heat exchanger the continuous conversion direction of motion of sending in the reactor of gas.
We can say that the intake and exhaust circulating system relates to rationally whether, concerning the height of the weary wind oxidation unit thermal efficiency.Conventional design, it generally is the mouth of respectively boxing out in device intake and exhaust chamber, both sides, to lack the general mood body and directly introduce and discharge oxidation unit by an end, this way is feasible reluctantly for small-sized oxidation unit, but for the weary large-scale plant of wind disposal ability more than tens thousand of cubes, gas is introduced by an end, through one several meters long passages (intake and exhaust chamber), the flow of gas and pressure have significantly decay more, and the gas flow and the pressure that are assigned to inner each position of device are extremely inhomogeneous, there is the immobilising dead angle of gas, increased the danger that sets off an explosion because of air accumulation.The circulation or the exchange system simplicity of design of domestic and international this type of device, the problem that ubiquity energy storage bed section temperature is inhomogeneous, heat storage capacity is poor, energy waste is serious.
The utility model content
The intake and exhaust circulation system design that the purpose of this utility model is to solve the weary wind oxidation unit of prior art is simple, cause the defective that the energy storage bed section temperature is inhomogeneous, heat storage capacity is poor, energy waste is serious, provide in the whole oxidation unit of a kind of assurance, weary wind intake evenly distributes, avoided the inner heat transfer free convection of device, do not produce air accumulation district (being the dead angle), improve the oxygenation efficiency of weary wind, reach the technical indicator of high accumulation of energy, the safe and reliable weary wind oxidation unit intake and exhaust circulating system.
The utility model is realized by following technical scheme:
It is a kind of weary wind oxidation unit intake and exhaust circulating system, comprise the intake and exhaust distribution pipe that is connected with the oxidation unit body, it is characterized in that being provided with between blower fan and the intake and exhaust distribution pipe special-shaped t-bend pipe of rectangle, the body of described special-shaped t-bend pipe lower end is provided with weary general mood body import and waste gas outlet, described intake and exhaust distribution pipe is a multiple-branching construction, comprise house steward and arm, described house steward is connected with the body of special-shaped t-bend pipe upper end, lower end respectively.
Described special-shaped t-bend pipe is provided with reversing control system, and described reversing control system comprises four electromagnetic valves, and described electromagnetic valve is installed on the body of special-shaped t-bend pipe upper and lower end, lays respectively at house steward's both sides.
House steward is equipped with explosion proof door with the position that special-shaped t-bend pipe upper and lower end body is connected.
The utility model alternately opens and closes by two one group of four electromagnetic valves, the switching of control electromagnetic valve realizes the conversion of gas flow, enters in the oxidation unit intensification of absorbing heat of weary general mood body thereby make in the thermal storage ceramic module, the temperature that keeps center cross-sectional is to guarantee keeping certainly of oxidizing process.
Key of the present utility model is the structure of intake and exhaust distribution pipe, and it directly influences even distribution and the oxygenation efficiency that enters the inner weary wind of oxidation unit.And the utility model adopts multiple-branching construction to avoid above problem, is applicable to the large-scale weary wind oxidation unit of all size.
Major advantage of the present utility model and beneficial effect are:
(1) reversing control system is set,, realizes the continuous conversion of gas flow, make the weary general mood body that the enters intensification of in regenerative apparatus, absorb heat, with keeping certainly of assurance oxidizing process by the switching time of control electromagnetic valve.
(2) the intake and exhaust distribution pipe is taked multiple-branching construction, and the streamline transition is passed through a plurality of arms with gas, be assigned to each position of oxidation unit uniformly, gas is evenly distributed at device inner flow and pressure, thereby make it more fully oxidation, improve the oxygenation efficiency of gas.And reduce the generation in the immobilising zone of gas as much as possible, avoid producing air accumulation.
(3) a plurality of explosion proof doors are set in the pipeline, blast, can effectively prevent the damage and the security incident of equipment by explosion proof door with explosion energy discharging safely and fast in case concentration transfinites.
This shows that the utility model is applied to the air inlet system and exhaust system of all kinds of weary wind oxidation units, safety, reliability, economy for improving oxidation unit all can produce good effect, thereby improve the economic benefit and the social benefit of weary wind oxidation unit.
