Background technique
Explosion-proof combustion engine is generally used for the inferior flammable explosive gas place that exists of coal mine, for transport, the mechanical work such as loading provide power, the common shortcoming of existing anti-explosion diesel unit is that pollution emission is administered greatly difficulty, a kind of close coupled type water jacket explosion-proof combustion engine gas exhaust manifold purifier is disclosed in Chinese utility model patent specification ZL201320518361.6, this purifier is arranged in gas exhaust manifold, it comprises explosive-proof sealed base plate, water sleeve exhaust steam passage, water jacket is the rectangular cavities structure being fixed on explosive-proof sealed base plate, between water jacket internal layer and explosive-proof sealed base plate, it is exhaust steam passage, explosion-proof base plate is provided with at least two suction ports that connect with waste gas, water jacket top is also provided with the exhaust pipe connecting with exhaust steam passage, exhaust pipe is cavity body structure, and cavity is communicated with water jacket, on suction port, sealing is provided with Purified core, exhaust pipe outer wall is provided with the cooling water inlet pipe being communicated with water jacket, on the outer wall of water jacket end, be also provided with the cooling water outlet connecting with water jacket.The unit waste gas treatment device that this gas exhaust manifold is integrated is arranged in gas exhaust manifold, because, the gas that gas exhaust manifold is discharged can carry out cooling, in this temperature, general oxidation catalyst cannot normally be worked, so purification ratio can be very low, but, for the less unit of some installing space, just can not realize and in gas exhaust manifold, complete control measures; In addition, this purifier is owing to being arranged in gas exhaust manifold, and therefore requirement of explosion proof is higher, and explosive-proof sealed base plate need to be set, and this explosion-proof base plate cost is higher, and more thick and heavy, has increased the manufacture cost of device, has also increased the weight of the weight of whole unit.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of water jacket explosion-proof combustion engine outlet pipe purifier, this purifier can be arranged on outlet pipe and reach the object of high-efficient purification, more so be suitable for the unit that some installing spaces are less, in addition, this purifier does not need to install explosive-proof sealed plate, can effectively reduce manufacture cost, and can alleviate the weight of unit entirety.
To achieve these goals, the utility model provides a kind of water jacket explosion-proof combustion engine outlet pipe purifier, comprise suction tude, water intake, Purified core, water outlet, steam outlet pipe, receiving cavity, exhaust elbow, described suction tude, steam outlet pipe, receiving cavity and exhaust elbow are the cavity body structure with water jacket, this receiving cavity one end is communicated with suction tude, the other end is communicated with one end of exhaust elbow, wherein the other end of exhaust elbow is communicated with steam outlet pipe, on the outer wall of receiving cavity, be communicated with water intake, on the outside of receiving cavity inwall, there is heat insulation coating, on outer wall at exhaust elbow away from one end of receiving cavity, be communicated with water outlet, described Purified core is fixed on the inwall of receiving cavity, on this Purified core, be coated with oxidized form noble metal catalyst.
As improvement of the present utility model, described exhaust elbow is double-layer stainless steel ripple shake structure.
As further improvement of the utility model, the longitudinal section of described receiving cavity is cylinder type, and described Purified core is the cylindric cellular structure with clear opening adapting with receiving cavity.
The utility model is by doing heat insulation coating on the outside purifying cavity wall, and on Purified core, apply oxidized form noble metal catalyst, so can be arranged on the object that realizes high-efficient purification waste gas on outlet pipe, then solved the problem that water jacket explosion-proof waste gas treatment device cannot be applicable to small unit, in addition, because this device is not mounted in gas exhaust manifold, so just avoided use bursting diaphragm, thereby reduce the fabricating cost of device and reduced the weight of installing, simultaneously, because exhaust elbow adopts double-layer stainless steel ripple shake structure, thereby the damage bringing to this device because of vibrations can effectively reduce unit work time.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, suction tude, 2, water intake, 3, Purified core, 5, water outlet, 6, receiving cavity, 7, steam outlet pipe, 8, exhaust elbow, 9, heat insulation coating.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of water jacket explosion-proof combustion engine outlet pipe purifier, comprise suction tude 1, water intake 2, Purified core 3, water outlet 5, steam outlet pipe 7, receiving cavity 6, exhaust elbow 8, described suction tude 1, steam outlet pipe 7, receiving cavity 6 and exhaust elbow 8 are the cavity body structure with water jacket, these receiving cavity 6 one end are communicated with suction tude 1, the other end is communicated with one end of exhaust elbow 8, wherein the other end of exhaust elbow 8 is communicated with steam outlet pipe 7, on the outer wall of receiving cavity 6, be communicated with water intake 2, on the outside of receiving cavity 6 inwalls, there is heat insulation coating 9, on outer wall at exhaust elbow 8 away from one end of receiving cavity 6, be communicated with water outlet 5, described Purified core 3 is fixed on the inwall of receiving cavity 6, on this Purified core 3, be coated with oxidized form noble metal catalyst.
While work because of unit, can produce violent vibrations, for fear of this vibrations, this purifier be produced to damage, can make described exhaust elbow 8 for double-layer stainless steel ripple shake structure.
For the ease of the making of receiving cavity 6, the longitudinal section that can make described receiving cavity 6 is cylinder type, and meanwhile, in order to improve purification efficiency, can make described Purified core 3 is the cylindric cellular structure with clear opening adapting with receiving cavity 6.
Because some small anti-explosion diesel engine unit limited spaces, in order to make this purifier more can adapt to some small units, water intake 2 is arranged on receiving cavity 6, instead of be arranged on other positions.
When this purifier work, waste gas enters receiving cavity 6 from be connected suction tude 1 with outlet pipe, on outside because of receiving cavity 6 inwalls, there is heat insulation coating 9, in the time that the waste gas of unit flows into receiving cavity 6 by suction tude 1, although the water intake 2 in water jacket from receiving cavity 6 outer walls flows into, the cooling water flowing out from water outlet 5, but there is heat insulation coating 9 on the outside of receiving cavity 6 inwalls, the exhaust gas temperature that so just can avoid entering in receiving cavity 6 reduces and has affected purification efficiency, simultaneously, on Purified core 3, be coated with oxidized form noble metal catalyst, this catalyzer is relatively suitable for being used in the environment that temperature is lower, so can ensure the high-efficient purification of waste gas.When waste gas is by after receiving cavity 6, on exhaust elbow 8 and steam outlet pipe 7, all there is no Insulation, so now waste gas can be lowered the temperature by the cooling water in water jacket, so that the exhaust gas temperature of discharging is lower.
