Description

CO in the direct purification exhaust gases of internal combustion engines 2Processing saving tank arrangement

Technical field:

CO in the direct purification exhaust gases of internal combustion engines ₂Processing saving tank arrangement, belong to atmosphere environmental protection science, exactly be to utilize potassium hydroxide solution to handle CO in the saving jar direct purification exhaust gases of internal combustion engines ₂Device.

Technical background:

In the routine techniques that in the past improvement exhaust gases of internal combustion engines pollutes, pay attention to for the flue dust in the tail gas and carbon hydride, NO more _X, SO ₂Administer purification with harmful gases such as CO, not seeing has CO in pair tail gas ₂The isolated plant of administering.

Summary of the invention:

The purpose of the present utility model is for a large amount of CO to containing in the existing exhaust gases of internal combustion engines directly ₂With minor N O _XCarry out purified treatment, to reduce discharging to the atmosphere greenhouse gases.

The utility model mainly is to be connected the tail gas path by the conventional exhaust gases of internal combustion engines path, the movable joint that in position are provided with adjusting control valve and pressure gauge and safety valve in addition to have the etch-proof potassium hydroxide solution of the cylinder bodily form that a plurality of air inlet tubule spiral shells withhold capping and handle the saving jar and support the related elasticity tray rack mechanically of internal-combustion engine that is fixed on of handling the saving jar and constitute, and it is characterized in that: have weldering and connect the suction tude spiral shell and withhold the etch-proof potassium hydroxide solution of the cylinder bodily form and the CO of capping ₂Reactor has purification CO ₂Integrative-structure with the saving resultant.

Technological scheme is specifically: 1, exhaust gases of internal combustion engines path of the present invention is on all types of conventional exhaust gases of internal combustion engines paths basis, other is provided with adjusting control valve easily, sensitivity is that the pressure gauge of percent point standard atmospheric pressure and pressure limiting are at the safety valve a little more than several percentage points of standard atmospheric pressures, path is divided into 2 parts by connecting movable joint outside adjusting control valve and the front and back, before adjusting control valve and the preceding movable joint is anterior path, is the rear part exhaust path behind adjusting control valve and the back movable joint.The function of adjusting control valve is effectively to control tail gas to enter the amount of handling the saving jar, guarantees that by the control of tail gas a jar interior reaction liquid is no more than 100 ℃, makes it carry out normal reaction; It is for referencial use for regulation and control tail gas amount that manometric function is to provide the anterior gallery pressure registration of tail gas; Automatic vent release of pressure when the function of safety valve is to surpass the security reaction pressure range in the path.The application of control valve, pressure gauge and safety valve is in order to realize that the anterior gallery pressure of tail gas is no more than the normal range (NR) a little more than several percentage points of ambient pressures, and a liquid temperature is no more than 100 ℃ normal reaction conditions in jar.

2, directly be connected in potassium hydroxide treatment saving jar behind the tail gas path movable joint, be divided into cover and two parts of cylinder bodily form tank body of having annular intake pipe and tubule.Sealing can be connected with the front and back movable joint of tail gas path respectively at the annular intake pipe of inwall and the steam outlet pipe at top on the cover, be communicated with a plurality of subsurface air inlet tubules of jar internal reaction that probe on the annular intake pipe in the lid, each parts all has corrosion-resistant coating in the cover, the tank body of reaction cartridge liquid is that the cylinder bodily form is made by anticorrosive, and cover is connected by the spiral shell buckle structure press seal that has sealed loop-pad with tank body.

3, in the various exhaust gases of internal combustion engines of existing conventional, mainly contain a large amount of CO ₂Minor N O _XAnd other harmful gas of trace, in process tank of the present invention, mainly carry out 2KOH+CO ₂=K ₂CO ₃+ H ₂O and KOH+NO _X→ K ₂NO ₃+ H ₂The chemical reaction of O, condition remain on reacting liquid temperature between normal temperature-100 ℃, press in jar a little more than about several percentage points of external atmosphere pressure, disposable canned KOH solution concentration about 35%, reaction back by-product K ₂CO ₃Content should reach stopping more than 80% of by-product mixture ratio.Changing jar re-uses and should be determined by service time and pressure gauge display parameters that experience is in advance measured.

4, the fixing flexible supporting frames of handling the saving jar is that cushion and tray bottom spring members constitute in the pallet by the circular support pallet on band card edge, and it is installed on the appropriate location of the related machinery of internal-combustion engine.

5, chemical reaction charging of the present invention and byproduct for treatment should be handled by specialized department's calibrating purchase and sale.

Advantage after the utility model is realized is: 1, the CO in the purification of exhaust gases of internal combustion engines basically ₂Discharging, 2, by-product is higher than the value that feeds intake, 3, installation cost is low has business development and be worth no environment public hazards.

Description of drawings:

Fig. 1: CO in the direct purification exhaust gases of internal combustion engines ₂Processing saving tank arrangement sectional elevation schematic representation

Sequence number among the figure: 1 exhaust gases of internal combustion engines path front portion, 2 tail gas path exhaust rear portions, 3, the tail gas adjusting control valve, 4 pressure gauges, 5 safety valves, the movable joint of 6 tail gas paths, the anterior stop valve of 7 tail gas paths, 8 are communicated with the air inlet ring pipe of tail gas path, 9 connect the air inlet tubule of ring pipe, 10 cover bodies, the press seal spiral shell button of 11 covers and tank body, 12 sealed loop-pads, 13 annular intake pipe fixing frames, 14 corrosion protection tank bodies, 15 tank body cold-proof heat insulation covers, 16 support pallet, cushion on 17 pallets, 18 supported spring parts.

Embodiment:

The present invention one is for example shown in Figure 1, and the exhaust gases of internal combustion engines path anterior 1 that has adjusting control valve 3 pressure gauges 4 safety valves 5 is connected with cover body 10 with exhaust rear portion 2 usefulness movable joints 6.Annular intake pipe 8 and fixing frame 13 solid weldings are on lid 10 inwalls, a plurality of air inlet tubules 9 are connected and insert on the annular intake pipe 8 under the reaction liquid level, cylinder bodily form corrosion protection tank body 14 is sealed with spiral shell button 11 and seal washer 12 that cover body 10 adopts spiral shell to withhold seal structure, and the integral body of processing saving jar is supported at the bottom of jar along pallet 16 cushions 17 and spring members 18 by the circular card of elasticity tray rack.

When exhaust gases of internal combustion engines by 1 by valve 7 when movable joint enters endless tube 8 tubules 9 and enters the KOH treatment fluid again, a large amount of CO in the tail gas ₂With minor N O _xTo carry out comprehensive chemical reaction in the KOH of disposable tinning solution, generate K ₂CO ₃, K ₂NO ₃And water, remainder of exhaust gas is discharged by tank top path 2.

The normal operation of this device is behind certain hour, the water that produces raises tank level, and pressing thereupon in the path 2 increases, and is presented on the pressure gauge 4 more, or be reflected in the exhaust release of pressure of safety valve 3, at this moment can stop using or more renew jar by measuring good empirical parameter decision in advance.

Elsewhere, in running,, can treat to use again behind the temperature drop artificially with adjusting control valve 3 regulation and control if when solution surpasses 100 ℃ in interim occur jar; Standby tank body winter protection glove 15 can be used in dead season.

Above structure of the present invention and enforcement, demonstrating it especially promptly is purifying internal combustion engine tail gas CO ₂Processor be again the saving jar of by-product potash fertilizer mixed solution.
