Description
Technical field
The present invention relates to a kind of airflow reversing mechanism of vertical coal mine ventilation air methane oxidation device, belong to super low concentration methane thermal counter flow oxidation and low-density technical field of energy recovery.
Background technology
Gas density in the coal mine methane is generally less than 1%, is difficult to utilize conventional burners directly to burn under the situation of auxiliary fuel not having.The hot counter flow oxidation device of coal mine methane can be oxidized to carbon dioxide and water with the gas that lacks in the wind, realizes reducing discharging, and reclaims heat wherein.The weary general mood body that gets into the oxidation unit oxidation bed intensification of from thermal storage ceramic, absorb heat, high-temperature region oxidation heat liberation in the middle part of oxidation bed, and discharge after heat passed to ceramic honey comb again.The key of this technology is will be with the continuous conversion flow direction of sending in the oxidation bed of gas, to guarantee keeping certainly of oxidizing process.Because the disposal ability of every cover coal mine methane oxidation unit generally at tens thousand of cubic metres/hours, does not also have special-purpose reversal valve at present.Coal mine methane oxidation unit in the past adopts four valves, realizes that the airflow direction of weary wind and waste gas switches.But that this commutating device exists is bulky, the sealing is bad, big, the shortcomings such as functional reliability is poor, installation and maintenance inconvenience of weary wind escape amount during switching-over.
Summary of the invention
The object of the invention is exactly to overcome or to avoid the shortcoming and defect that exists in the above-mentioned prior art; A kind of integrated vertical coal mine ventilation air methane oxidation device airflow reversing mechanism is provided; It is connected with the last next part case of oxidation unit, alternately switches the airflow direction of turnover oxidation bed reliably.
The objective of the invention is to realize by following technical proposals:
A kind of vertical coal mine ventilation air methane oxidation device airflow reversing mechanism; It is characterized in that: comprise upper cavity, lower chamber, tube connector and exhaust valve chamber between upper cavity and lower chamber and air inlet valve chamber; Wherein exhaust valve chamber and air inlet valve chamber are respectively through tube connector and upper cavity and lower chamber UNICOM; And the tube connector that connects exhaust valve chamber upper and lower end face is located along the same line; The tube connector that connects air inlet valve chamber upper and lower end face also is located along the same line, and the connection position of tube connector and exhaust valve chamber and air inlet valve chamber is equipped with valve seat; The upper surface that upper cavity is positioned at top, tube connector center is equipped with the pilot seal cover; The lower end that is fixed on the piston rod of two cylinders on two cylinder blocks is fixedly connected with the upper end of valve rod through the cover that is threaded; Two valve rods pass pilot seal cover, upper cavity and tube connector successively, and it is indoor to probe into exhaust valve chamber and intake valve respectively, and the bottom is fixedly connected with valve plate; When valve plate moves upward with valve rod; The valve plate shutoff is on the valve seat of exhaust valve chamber and air inlet valve chamber upper surface, and when valve plate moved downward with valve rod, the valve plate shutoff was on the valve seat of exhaust valve chamber and air inlet valve chamber lower surface; The opening part of the sidewall of upper cavity, lower chamber, exhaust valve chamber and air inlet valve chamber is equipped with flange, and the corresponding cavity wall of the flange on the upper cavity, lower chamber adopts the orthodrome transition.
Described vertical coal mine ventilation air methane oxidation device airflow reversing mechanism, the longitudinal centre line of the end face of flange of the end face of flange of the end face of flange of upper cavity sidewall, lower chamber sidewall, air inlet valve chamber sidewall, air inlet valve chamber, exhaust valve chamber is parallel to each other and is positioned at same plane.
Described vertical coal mine ventilation air methane oxidation device airflow reversing mechanism; In upper cavity and lower chamber, be provided with a plurality of deflectors longitudinally; Deflector is the radial mouth of pipe around the tube connector that connects the air inlet valve chamber towards the flange side, and the upper and lower end of deflector is fixedly connected with the upper and lower inwall of upper cavity and lower chamber respectively.
Its operation principle is: when oxidation unit was worked, the indoor valve plate position of valve plate that intake valve is indoor and air bleeding valve was always opposite.If it is the next that the indoor valve plate of intake valve is in, then the indoor valve plate of air bleeding valve is in upperly, and two valve plates are closed the tube connector of air inlet valve chamber downside and the tube connector of exhaust valve chamber upside simultaneously.At this moment; Get in the tube connector entering upper cavity of coal mine methane gas through upside of air inlet valve chamber; Get into upper collecting chamber, the oxidation bed of oxidation unit then, oxidation in oxidation bed, the gas after the oxidation gets in the lower chamber through oxidation unit next part case; Tube connector through downside gets into the exhaust valve chamber, after the flange discharge of air bleeding valve chamber.When oxidation unit need commutate, under the control of automatic control system, two cylinders moved simultaneously; The valve plate of air inlet valve chamber is mentioned valve plate upper, the exhaust valve chamber to be pushed into the next; The air inlet valve chamber is communicated with lower chamber, and the exhaust valve chamber is communicated with upper cavity, gets in the tube connector entering lower chamber of coal mine methane gas through downside of air inlet valve chamber; Next part case through oxidation unit gets into oxidation bed; Gas after the oxidation gets in the upper cavity through the oxidation unit upper collecting chamber, through the tube connector entering exhaust valve chamber of upside, after the flange discharge of air bleeding valve chamber.So alternate cycles work.
The present invention compared with prior art, major advantage and beneficial effect are:
1, the airflow reversing mechanism of vertical coal mine ventilation air methane oxidation device of the present invention adopts integrated morphology, compact conformation, and volume is less; Upper cavity is connected with the upper collecting chamber of oxidation unit through flange, and lower chamber is connected with the next part case of oxidation unit through flange, and is easy for installation.Be flat seal between valve plate and the valve seat, be threaded to overlap through adjustment and can regulate the compressing degree between valve plate and the valve seat, good sealing effect, reliable operation.
2, between air inlet valve chamber, exhaust valve chamber and upper cavity, lower chamber, adopt four tube connectors to be connected, further reduced the volume that weary general mood body is flowed through in the valve body, thereby the not oxidation that has further reduced to cause because of switching-over lacks the escape amount of general mood body.
3, the side wall surface of upper cavity and lower chamber adopts the orthodrome transition; And be provided with deflector; Thereby make weary general mood body through behind the airflow reversing mechanism, get into the upper collecting chamber or the next part case of oxidation unit equably, for ventilation air gas in oxidation bed equably oxidation created condition.
