Low temperature cleaning treatment device of anti-explosion diesel engine tail gas in coal mine

Abstract

The invention relates to a low temperature cleaning treatment device of an anti-explosion diesel engine tail gas in a coal mine. The cleaning treatment device comprises an anti-explosion diesel engine provided with a tail gas outlet and a tail gas processing device connected with the tail gas outlet end of the anti-explosion diesel engine, wherein the tail gas processing device comprises a tail gas exhaust pipe connected with the tail gas outlet end, a cooling pipeline arranged outside the tail gas exhaust pipe and used for cooling the tail gas exhaust pipe, and a cold air delivery mechanism used for automatically delivering cold air to the cooling pipeline; and a purification plant is arranged in the tail gas exhaust pipe. The cleaning treatment device provided by the invention has the advantages that the structure is simple, the occupied space is small, the tail gas is capable of being cooled to safe temperature and purified, and then the cooled and purified tail gas is discharged; the security of work in the coal mine is improved, thereby avoiding the damage of the tail gas to the physical and psychological health of task staff; and meanwhile, compared with the prior art, the device has the advantages that the tail gas discharge resistance is avoided, the power of the anti-explosion diesel engine is guaranteed, the oil consumption is reduced, and the cost is saved.

Description

technical field [0001] The invention relates to a tail gas treatment device, in particular to a low-temperature purification treatment device for an explosion-proof diesel engine tail gas under a mine. Background technique [0002] Explosion-proof diesel engines are necessary machinery for power supply in mine mining and transportation. At present, the exhaust emission treatment method of mining explosion-proof diesel engines is mostly to use water bath cooling devices, which have many components and large volumes, and are inconvenient to transport. And the scope of occupied underground space is bigger; This kind of method is to discharge after the exhaust gas of explosion-proof diesel engine is filtered through the cooling water in the exhaust gas treatment box, thereby must clean the colloid and depositing in the box every day. Therefore, the wastewater treatment of the water bath cooling system is not only labor-intensive for the operators; but also the cooling water that...

[0002] Explosion-proof diesel engines are necessary machinery for power supply in mine mining and transportation. At present, the exhaust emission treatment method of mining explosion-proof diesel engines is mostly to use water bath cooling devices, which have many components and large volumes, and are inconvenient to transport. And it occupies a large range of underground space; and this method is to filter the exhaust gas of the explosion-proof diesel engine through the cooling water in the exhaust gas treatment box and then discharge it, so that the colloid and sediment deposited in the box must be cleaned every day.

Therefore, the wastewater treatment of the water bath cooling system is not only labor-intensive for the operators; but also the cooling water that consumes a lot, due to the difficulty of replenishing water underground, once the water is short and the temperature of the exhaust gas is too high, it is easy to cause a gas explosion and endanger Safe; and because the exhaust gas is first discharged into the cooling water and then discharged, the exhaust resistance is relatively large, which reduces the power of the engine and increases the fuel consumption; If it fails to meet the emission standards stipulated by the state, it will still cause certain pollution to the underground environment and directly affect the physical and mental health of the operators.
