The present invention relates to a kind of device to combustion process high-temperature tail gas harmless treatment, belong to technical field of waste gas treatment.

Background technology

Burning, as a kind of method of supplying of the energy, serves the productive life of the mankind, it may be said that be ubiquitous.Same in laboratory, various combustion experiments are also in an endless stream, and therefore various waste gas dust are also a lot, the CO that such as imperfect combustion produces, containing the SO that S material produces2, and it is used for the titanium dioxide solids granule of combustion experiment etc..The waste gas that burning is produced by a lot of people is all be directly discharged in air, and somebody can simply process, but waste gas and solid particle can not be completely eliminated, and this has resulted in the pollution to atmospheric environment, and therefore we should pay attention to this problem.

Summary of the invention

The present invention is to solve the problems referred to above, it is provided that a kind of tail gas hazard-free processes device, and this device volume is little, simple in construction, and cost of manufacture is low, it is simple to clean;Can fully absorbing the deleterious particle in tail gas, efficiency is high, can fully reduce the exhaust temperature of tail gas simultaneously, protects environment.

For solving above-mentioned technical problem, the invention provides a kind of tail gas hazard-free and process device, mainly include an exhaust gas processing device and a wastewater treatment equipment;Exhaust gas processing device includes casing, some shower nozzles, baffle plate, and waste water collection device mainly includes a wastewater filtering device, and shower nozzle is evenly distributed on casing top end surface, and baffle plate is fixed on the centre of casing by draw-in groove, forms roundabout " U " type passage;Inlet exhaust gas and outlet lay respectively at right left two upper lateral parts of casing, are provided with drainage screen in offgas outlet simultaneously;Wastewater outlet is positioned at box bottom side;Wastewater filtering device is positioned at outside casing, and wastewater outlet is connected with wastewater filtering device by pipeline, and wastewater filtering device is connected with shower nozzle by pipeline, and water enters shower nozzle by suction pump.

Further, along airflow direction, the water smoke droplet size that shower nozzle is sprayed downwardly out changes from fine to coarse.

Further, casing front end is provided with one piece of anterior flat board that can dismantle, and anterior flat board top is provided with an observation window.

Further, the width of baffle plate, equal to the width of casing, is highly the 2/3 of box height.

Further, inlet exhaust gas and offgas outlet are at sustained height, and are provided with drainage screen in offgas outlet.

Further, baffle plate is three pieces, two pieces are stretched into from casing top end surface draw-in groove, it is suspended in casing, distance is box height the 1/3 of distance casing bottom, baffle plate bottom, in other one piece of draw-in groove being arranged on casing bottom end surface, it is positioned at the centre of two pieces of baffle plates, distance is box height the 1/3 of distance casing top, baffle plate top.

Further, the distance of centrally located baffle plate and two side shields is equal, and spacing distance is the 1/4 of casing length, to reach the adsorption effect of the best.

Further, water can recycle.

Further, being placed with solid particle adsorbing material, the solid particle that absorption is got off by current band in defecator, decontamination cycle water makes it to recycle.

During work, shower nozzle produces the water smoke of fully atomization and is full of whole casing, 3 pieces of baffle plates are fixed by draw-in groove, are primarily to the movement locus changing tail gas so that tail gas and water smoke are sufficiently mixed, increase the absorption of exhaust particulate, reducing temperature, final waste water is entered wastewater filtering device by wastewater outlet, and the water being filtrated to get is used further to spraying, to reach the effect of water circulation, save the consumption of water.

The Advantageous Effects that the present invention reaches:

1. in combustion experiment, it is possible to absorb the fine particle added in tail gas and burning other solid particles produced, reduce exhaust temperature.

2., in all kinds of experiments having tail gas, if contained solid particulate matter is a lot, vent gas treatment can be carried out with this device.

3., in all kinds of productive lifes, the process for dust can use this device.

4. for the purification of room air, especially indoor dust, it is possible to use this device.

Accompanying drawing explanation

Fig. 1 is present configuration schematic diagram.

Wherein: 1 shower nozzle;2 draw-in grooves;3 inlet exhaust gas;4 baffle plates;5 wastewater outlets;6 defecators;7 cycling use of waters;8 observation windows;9 offgas outlet;10 drainage screens;11 casings.

Detailed description of the invention

In order to be able to be better understood by the technical characteristic of the present invention, technology contents and its technique effect reached, now the accompanying drawing of the present invention is described in detail in conjunction with the embodiments.

As it is shown in figure 1, the invention provides the device that a kind of tail gas hazard-free processes, mainly include an exhaust gas processing device and a wastewater treatment equipment.Exhaust gas processing device includes casing 11,1,3 pieces of baffle plates 4 of shower nozzle and 1 observation window 8, and waste water collection device mainly includes a wastewater filtering device 6.During work, some shower nozzles produce the water smoke of fully atomization and are full of whole casing, and 3 pieces of baffle plates 4 are fixed by draw-in groove 2, are primarily to the movement locus changing tail gas so that tail gas and water smoke are sufficiently mixed, and increase the absorption of exhaust particulate, reduce temperature.Final waste water is entered wastewater filtering device 6 by wastewater outlet 5, and the cycling use of water 7 being filtrated to get is used further to spraying, to reach the effect of water circulation, saves the consumption of water.

Described inlet exhaust gas 3 and offgas outlet 9 are positioned at sustained height.

It is provided with drainage screen 10 in described offgas outlet 9.

Described anterior flat board is detachable, convenient cleaning.

Described three pieces of baffle plates 4 are fixed by draw-in groove 2.It is used for extending the tail gas time of staying in casing so that tail gas and solid particle and water smoke can be sufficiently mixed, and reaches the effect of dedusting cooling.

Described cycling use of water 7 can be recycled, and reaches to solve the effect of water resource.

The operation principle of the present invention: tail gas enters in casing 11 to walk around baffle plate 4, produces very thin very close water smoke by shower nozzle 1 and to be sufficiently mixed with tail gas, waited until that, near offgas outlet 9, the solid particle in tail gas will be greatly reduced.Waste water in casing 11 then enters into defecator 6 through wastewater outlet 5, and the cycling use of water 7 obtained after filtration is then again passed in shower nozzle 1 and produces water smoke, and tail gas is discharged in air after cooling dedusting again.

Above, announce the present invention with good embodiment, but not be used for limiting the present invention, every take equal replace or equivalent transformation method or technical scheme all in protection scope of the present invention.
