The device serves the functions of exhaust explosion prevention and motor tail gas purification; the explosion prevention effect is safe and reliable, and the tail gas purification effect is good; and the device has the advantages of simple, compact and reasonable structure and good application effect, and integrates fire extinguishing and waste gas purification as a whole.
Description
Technical field
The present invention relates to the explosion-proof and filtration equipment for clarifying of a kind of exhaust, be particularly useful for the filtration that motor exhausts such as underground diesel machine, petrol engine are explosion-proof and purify, also be applicable to the exhaust gas purification filter of ground large diesel power generation unit.
Background technique
Working environment inflammable and explosive under the coal mine has explosion-proof performance to normal requirement of some electromechanical equipments, could guarantee the safety of mining.The present explosion-proof and water washing box that uses of downhole anti-explosion diesel engine, employing be bigger casing, in the water washing box bottom water impeller is arranged.When engine exhaust passed through the grid type flameproof apparatus, gas is discharging and the flame extinction that possibility is residual more after filtering.These characteristics explosion-proof and water washing device are that structure is bigger, engine exhaust through the time can not well filter washing, most of waste gas through the washing and directly be not discharged in atmosphere or the tunnel, the tail gas clean-up effect is relatively poor.
Summary of the invention
The objective of the invention is provides a kind of simple in structure to the problem that exists in the prior art, and using effect is good, integrates the explosion-proof and filtration equipment for clarifying of diesel exhaust gas of fire extinguishing, waste-gas cleaning.
For realizing above-mentioned purpose; Technological scheme of the present invention: the filter housings that washing filtering liquid is housed bottom comprising; The periphery of filter housings is provided with the elbow suction tude, and is provided with impeller in the filter housings of elbow suction tude corresponding position, and an end face of filter housings is provided with the bearing support of supporting outlet pipe; The other end is provided with the bearing support of supporting impeller; Be provided with both ends of the surface in the filter housings and be individually fixed in the explosion-proof sieve of filtration on outlet pipe and the impeller, the top of filter housings is provided with spout, and the bottom is provided with pollutant exhaust hole and screw plug.
Be provided with gas seal ring in the described bearing support; Said elbow suction tude is offset on the filter housings; The explosion-proof sieve of described filtration constitutes by network framework with attached to the single or multiple lift screen cloth on the network framework; Be attached with the corrosion resistant layer on the internal surface of said filter housings.
Beneficial effect: explosion-proof effect is safe and reliable, and good tail gas clean-up effect is arranged, and has the exhaust explosion prevention function; When tail gas when suction tude gets into; Promote filter screen casing fan and promote the blade rotation, filter screen casing fan promotes gas filtration and explosion-proof net rotation in the blade drive, forms moisture film on gas filtration and the explosion-proof net in washing filtering liquid adheres to; Form water film dedusting, prevented the propagation of flame in outlet pipe effectively.The function that has the harmful gases such as oxynitrides of scavenging in addition contains alkalescence in the filtered fluid of use, can be with harmful gases such as the oxynitrides reaction of waste gas.Be particularly useful for the filtration that motor exhausts such as underground diesel machine, petrol engine are explosion-proof and purify, also be applicable to the exhaust gas purification filter of ground large diesel power generation unit.It is simple in structure, compact and reasonable, and using effect is good, integrates fire extinguishing, waste-gas cleaning, has practicability widely.
Description of drawings
Fig. 1 is a main TV structure schematic representation of the present invention.
Fig. 2 is a right TV structure schematic representation of the present invention.
Among the figure: outlet pipe-1, bearing support-2, filter housings-3, network framework-4 filters explosion-proof sieve-5, washing filtering liquid-6, pollutant exhaust hole and screw plug-7, elbow suction tude-8, impeller-9, bearing support-10, liquid filling hole-11.
Embodiment
Below in conjunction with accompanying drawing one embodiment of the present of invention are done further to describe:
Shown in Figure 1, the explosion-proof and filtration equipment for clarifying of exhaust, mainly by filter housings 3, elbow suction tude 8, outlet pipe 1, impeller 9 constitutes with the explosion-proof sieve 5 of filtration.The filter housings 3 of filtered fluid 6 is housed bottom it comprises, elbow suction tude 8 is offset on the periphery of filter housings 3, and its shaft axis does not overlap with the shaft axis of filter housings 3, and is shown in Figure 2.Impeller 9 is located in the filter housing 3 of elbow suction tude 8 inlet corresponding positions, and an end face of filter housings 3 is provided with the bearing support 2 of supporting outlet pipe 1, and the other end is provided with the bearing support 10 of supporting impeller 9, is provided with gas seal ring in the bearing support 2.Outlet pipe 1 is fixed on the filter housings 3 through bearing support 2; The one of which end stretches in the filter housings 3; Link to each other with explosion-proof sieve 5 one ends of filtration in being located at filter housings 3, the other end that filters explosion-proof sieve 5 links to each other with impeller 9, and impeller 9 is fixed in the filter housings 3 through tail bearing seat 10.Filter housings 3 bottoms fill washing filtering liquid 6, and the highest spacing foot that is lower than outlet pipe 1 of washing filtering liquid 6 is attached with the corrosion resistant layer on the internal surface of filter housings 3.Filtering explosion-proof sieve 5 constitutes by network framework 4 with attached to the single or multiple lift screen cloth on the network framework 4.The top of filter housing 3 is provided with spout 11, and the bottom is provided with pollutant exhaust hole and screw plug 7.
