Basic ideas of the present invention are, in large greenhouse heating system fire coal or oil burning boiler institute exhaust gas discharged, contain a large amount of carbonic acid gas, utilize chemical reaction, harmful components such as the sulphide that absorption is wherein contained, nitrogen oxide, reach the degree of abundant purification, can be discharged in the greenhouse as carbon-dioxide gasfertilizer.
Technical scheme of the present invention is that large greenhouse carbonic acid gas application device comprises:
The reative cell of a splendid attire reactant liquor, delivery pipe and vent valves are equipped with in its bottom; Its sidewall middle part has the perforate that is arranged above and below to communicate with spray chamber and pump impeller operating room respectively; The filler of filling reactant liquor is arranged at its side wall upper part or top, and the gas outlet is arranged at its top;
A blast tube is arranged on the top of described reative cell, and its air inlet is connected with the boiler exhaust gas road, and the gas outlet communicates with spray chamber by wireway;
One or more spray chambers are installed in the sidewall of above-mentioned reative cell, communicate with it by the reative cell side-wall hole, and described wireway is inserted in its top, and its below communicates with the pump impeller operating room by deflector;
One or more pump impellers operating room is arranged at the below of described spray chamber, and its top communicates with described spray chamber by described deflector, and its side communicates with it by described reative cell side-wall hole;
One or more centrifugal pump impellers are connected with drive link, are arranged in the described pump impeller operating room;
One or more atomizers are connected with drive link, are arranged in the described spray chamber;
One or more electromotor are installed in the sidewall of described reative cell, drive described drive link, centrifugal pump impeller, atomizer rotation by shaft joint or belt.
The course of work of the present invention is, after connecting power supply, the centrifugal pump impeller high speed rotating of motor drives, reactant liquor in the pump impeller operating room is discharged into reative cell, form negative pressure in the pump impeller operating room, the reactant liquor in the spray chamber flows to the pump impeller operating room by deflector, forms negative pressure in the spray chamber, reactant liquor in the reative cell flows to spray chamber simultaneously with the combustion gas that comes from gas pipeline, under the effect of atomizer high speed rotating, the reactant liquor that enters spray chamber is pulverized, and forms atomizing, fully contact with the combustion gas that enters spray chamber, carry out chemical reaction, combustion gas is purified, gas liquid mixture flows into the pump impeller operating room then, entered reative cell by pump impeller, gas-liquid is further contacted, and combustion gas is purified once more, overflows liquid level then, form malleation, send into the greenhouse by the road from the reative cell gas outlet.
Because the present invention utilizes large greenhouse heating system fire coal or oil burning boiler institute exhaust gas discharged to originate as carbonic acid gas, the present invention is relatively simple for structure in addition, so use cost is very low, and can play environmental-protection function.
