Description
Technical field
The present invention relates to tail gas cleaning applications, spy is related to a kind of anti-explosion diesel engine tail gas cleaning device.
Background technology
When anti-explosion diesel engine is used for underground working, underground working has 2 points of particular/special requirements to electromotor：One is well
Under need to prevent gas explosion, forbid high temperature or naked light, and the exhaust temperature of Diesel engine be up to 300-400 degree, 70 need to be down to
Below degree；Two is that subsurface environment is relatively airtight, need to strictly control the dust granules of electromotor, the discharge of harmful gass.Thus, use
Anti-explosion diesel engine in down-hole generally arranges water washing chamber, and tail gas discharges after washing cooling, dust suction again.
But, because the temperature of tail gas is higher, cause the water temperature of water supply tank also very high, increased evaporation of water speed, cause
So that the water of water supply tank is discharged and ruing out of quickly with gas, tend not in the finite capacity of water supply tank, and mine in time
Moisturizing, impact electromotor normally uses.The preferable mine of partial condition, is provided with moisturizing point every 1 kilometer, but most mine is little
Even without setting moisturizing point.Underground working is complicated, and electromotor has often been climbed, born a heavy burden, and water consumption is larger.Reality is frequent
There is a problem of that wash water shortage affects work.Meanwhile, there is also, when discharge reduction, tail gas is directly moved through from bottom to top
Cheng Zhong, short for time of contact with water, the dust in tail gas absorbs halfway shortcoming.
Content of the invention
For the deficiencies in the prior art, the invention provides a kind of anti-explosion diesel engine tail gas cleaning device.The present invention
By increasing heat exchanger after the offgas duct of electromotor and water supply tank, reduce temperature before entering water tank for the tail gas, pass through
Reduce water temperature and evaporation of water speed is greatly reduced, and then reduce the water consumption of down-hole water tank.Meanwhile, heat-insulated by increasing
Plate, when the water yield is few it is ensured that tail gas and water time of contact length it is ensured that the cleaning performance of dust.
The technical scheme is that：A kind of anti-explosion diesel engine tail gas cleaning device, including water inlet pipe, outlet pipe,
Heat exchanger, escape pipe, cleaning water tank, air inlet pipe and water supply tank it is characterised in that：The offgas duct of described electromotor pass through into
Trachea is connected with the air inlet of heat exchanger, and the outlet of water supply tank passes through the water inlet of water inlet pipe and heat exchanger, heat exchange
The outlet of device is connected with outlet pipe, and outlet pipe stretches in cleaning water tank from the top of cleaning water tank, the gas outlet of heat exchanger
It is connected with escape pipe, escape pipe stretches into cleaning water tank bottom from the top of cleaning water tank.
According to anti-explosion diesel engine tail gas cleaning device as above it is characterised in that：In described cleaning water tank
Bottom arranges thermal insulation board, and thermal insulation board arranges pore, and pore is individually positioned in, with the venthole of escape pipe, the both sides cleaning water tank.
According to anti-explosion diesel engine tail gas cleaning device as above it is characterised in that：Described water supply tank and sending out
The offgas duct of motivation is not less than the highest plane of cleaning Water in Water Tanks.
According to anti-explosion diesel engine tail gas cleaning device as above it is characterised in that：The going out of described outlet pipe
Mouth is arranged on thermal insulation board lower region.
According to anti-explosion diesel engine tail gas cleaning device as above it is characterised in that：Increase in described air inlet pipe
If the second check valve, described water inlet pipe is set up the first check valve.
The invention has the beneficial effects as follows：One is that the cleaning water tank overall temperature base of a fruit is relatively low, slow down evaporation of water speed, delays
Use time；Two are to ensure that when the water yield is few, tail gas and water time of contact length it is ensured that the cleaning performance of dust.
Brief description
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of another embodiment of the present invention.
Description of reference numerals：Electromotor 1, offgas duct 2, water inlet pipe 3, outlet pipe 4, heat exchanger 5, escape pipe 6, rinse water
Case 7, thermal insulation board 8, pore 9, water supply tank 10, the first check valve 11, the second check valve 12, air inlet pipe 13.
Specific embodiment
Below in conjunction with accompanying drawing, technical scheme is described further.
As shown in figure 1, the anti-explosion diesel engine tail gas cleaning device of the present invention includes water inlet pipe 3, outlet pipe 4, heat friendship
Parallel operation 5, escape pipe 6, cleaning water tank 7, air inlet pipe 13 and water supply tank 10, the offgas duct 2 of electromotor 1 is passed through air inlet pipe 13 and is handed over heat
The air inlet of parallel operation 5 connects, and the outlet of water supply tank 10 passes through the water inlet of water inlet pipe 3 and heat exchanger 5.Heat exchanger 5
Outlet is connected with outlet pipe 4, and outlet pipe 4 stretches in cleaning water tank 7 from the top of cleaning water tank 7.The gas outlet of heat exchanger 5
It is connected with escape pipe 6, escape pipe 6 stretches into cleaning water tank 7 bottom from the top of cleaning water tank 7.In the present invention, water supply tank 10 and sending out
The offgas duct 2 of motivation 1 is preferably not below the highest plane cleaning water in water tank 7, is so easy to current and air-flow automatically flows into clearly
In water tank 7.
The work process of the present invention is：Tail gas enters heat exchanger 5 through offgas duct 2, air inlet pipe 13, finally by escape pipe
Tail gas is caused cleaning water tank 7 bottom by 6, and the water of water supply tank 10 is flowed into clearly by water inlet pipe 3, heat exchanger 5 and outlet pipe 4 simultaneously
In water tank 7, realize cleaning water tank 7 is carried out with the function of automatic water supplement.Benefit of the invention is, supplements in water supply tank 10
