Abstract
The utility model discloses a comprehensive waste gas processing system of an explosion-proof diesel. The comprehensive waste gas processing system of the explosion-proof diesel is provided with a cooling water jacket, an inlet of the cooling water jacket is connected with an exhaust port of the diesel, a flame arrester is arranged at an outlet end of the cooling water jacket, and a cooling cavity of the cooling water jacket is communicated with a water tank through a water pump, wherein the cooling water jacket is of a U-shaped structure, water is accommodated in the inner cavity of the cooling water jacket, a water level controller is arranged in the inner cavity of the cooling water jacket, and an electromagnetic valve is controlled to be opened and closed by the water level controller. The comprehensive waste gas processing system of the explosion-proof diesel plays roles in cooling waste gas, extinguishing sparks and reducing the surface temperature of an exhaust pipe, and ensures that the whole exhaust system and final tail gas meet explosion protection requirements.
Description
Technical field
The utility model relates to inflammable and explosive place diesel engine high-temperature tail gas treatment technology, specifically a kind of explosion-proof type diesel engine vent gas total system.
Background technique
The place that is difficult for using grid power and needs high-power power source at some, just need to use high-power (four cylinders and more than) diesel engine as power, but often be attended by flammable explosive gas (for example natural petroleum gas field) in these operation areas, should use in these zones the diesel engine that possesses explosion prevention function, the guarantee job safety.So the research of high-power diesel engine high-temp waste gas comprehensive treatment technique has important practical significance.
In inflammable and explosive place, discharge high-temp waste gas in the diesel engine running, contain Mars in waste gas simultaneously, these very easily become Ignition sources, the research of the explosion-proof technology of high-power diesel engine causes the heavy losses of property and casualties, so will be carried out integrated treatment to waste gas.
The model utility content
The purpose of this utility model is the problem for existing vent systems high temperature, design a kind of explosion-proof type waste gas total system, take into account the effect of waste gas cooling, fire extinguishing star, reduction outlet pipe surface temperature simultaneously, make whole vent systems and final tail gas reach requirement of explosion proof.
For achieving the above object, the technical solution of the utility model is:
This explosion-proof type diesel engine vent gas total system, there is cooling jacket, the air inlet entrance of described cooling jacket connects the diesel exhaust gas mouth, the outlet end of cooling jacket is provided with flame trap, the cooling chamber of described cooling jacket is by the water pump joining water box, the water outlet joining water box, it is characterized in that: the described cooling jacket structure that takes the shape of the letter U, fill the water for the star of putting out a fire in the inner chamber of cooling jacket, the outer wall of described cooling jacket is provided with water level controller, the both sides of water level controller are by stretching to the inner chamber of cooling jacket connecting tube, submerge the connecting tube of lower end in water, the connecting tube of upper end is positioned on liquid level, described water level controller underpart is communicated with tee pipe fitting, another two outlets of described tee pipe fitting are connected with respectively ball valve and entering water electromagnetic valve, entering water electromagnetic valve is controlled by water level controller.
Be provided with splash-back in the inner chamber of described inner casing.
Described water tank is provided with level meter.
Realize principle: high-temp waste gas enters total system inside by exhaust gas inlet, the water that waste gas enters in rear and cooling jacket carries out heat exchange, along with the movement of gas in the cooling jacket inner casing, temperature progressively reduces, when high speed tail gas arrives bottom spark arrester (water), at first waste gas contact with the water surface in spark arrester, can extinguish Mars wherein.In order to guarantee fire extinguishing property effect, by controlling solenoid valve, Water in Water Tank is injected to water base spark arrester inside, and keep certain water level.Simultaneously, in gas and spark arrester, water surface Contact Temperature can further reduce.The waste gas that finally meets explosion-proof emission request enters atmosphere by flame trap.In order to guarantee the cooling-down effect of system, this system is strengthened circulation by water pump, by extracting the water in water tank, pumps into the cooling jacket water intake, through with water jacket in the high-temperature gas heat exchange, finally flow back into water tank.Simultaneously, by the double-layer water jacket effect, can guarantee that the high temperature of waste gas can not be transmitted to the cooling jacket shell, guarantee that its hot face temperature is no more than 100 ℃, guarantee that the exhaust treatment system skin temperature reaches the requirement of T4 (135 ℃) group explosive-proof grade.Compared with prior art, the invention has the beneficial effects as follows: 1, realize the effect of waste gas cooling, fire extinguishing star, reduction outlet pipe surface temperature simultaneously; 2, toxic emission temperature can meet T3 or T4 requirement of explosion proof; 3, Mars is flutterred collection rate high (can reach 99%); 4, case surface temperature lower (being no more than 100 ℃).
The accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
