The nozzle is in threaded connection with the slurry pipe, the cover cap is in threaded connection with the air pipe and seals the nozzle in a pressing way, andthe nano-bubble generation device and the booster pump are connected on the slurry pipe in series, so that the water-coal-slurry sprayed out contain a large number of nano-bubbles. The utility modelhas the advantages of improving the combustion efficiency, reducing the content of the residual carbon, lowering the viscosity and facilitating the spraying.
Description
Technical field
The utility model belongs to combustion apparatus, particularly the water-coal-slurry spray gun.
Background technology
Spray gun is a vitals in the cool water mixture burning equipment, though developed at present the spray gun that polytype differs from one another, anti-blocking, anticreep is fiery, certain effect is arranged in the atomizing, but efficiency of combustion is not high, burning back carbon residue content height both wasted energy, again contaminated environment.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes existing spray gun, provides a kind of and can improve efficiency of combustion, reduces the nano bubble water-coal-slurry spray gun of burning back carbon residue content.
The technical solution of the utility model is: nano bubble water-coal-slurry spray gun comprises cover cap, nozzle, locating flange, slurry pipe, left adpting flange, sealing ring, right adpting flange, oil inlet pipe control valve, oil inlet pipe, booster pump, delivery pump, water-coal-slurry inlet valve, scavenging air control valve, scavenging air air inlet pipe, nano-bubble generating apparatus, atomizing air control valve, atomizing air air inlet pipe, tracheae.Be connected in series booster pump successively on the slurry pipe, nano-bubble generating apparatus, delivery pump and water-coal-slurry inlet valve, slurry pipe side is provided with oil inlet pipe and scavenging air air inlet pipe, connect the oil inlet pipe control valve on the oil inlet pipe, connect the scavenging air control valve on the scavenging air air inlet pipe, slurry pipe and tracheae are arranged in concentric circles, sealed at both ends, the slurry pipe is little, tracheae is big, forming the ring-like gas passage that atomized between slurry pipe and the tracheae is communicated with the nozzle center hole by the nozzle inclined hole, the tracheae side is provided with the atomizing air air inlet pipe, connect the atomizing air control valve on the atomizing air air inlet pipe, nozzle is bolted on the slurry pipe, the cover cap is bolted on the tracheae and compresses nozzle and an end of the ring-like gas passage that atomized of sealing, the other end of the ring-like gas passage that atomized is sealed by left adpting flange, and locating flange is socketed on the tracheae cylindrical, and nano-bubble generating apparatus adopts the big cutting type nano-bubble generating apparatus that spirals of gas production.
Using method of the present utility model and operating principle are as follows: during the preheating oil spout, open the oil inlet pipe control valve, pressure oil is in oil inlet pipe advances pulp-entering pipe, enter nozzle center's hole ejection along the slurry pipe, open the atomizing air control valve simultaneously, compressed air enters the ring-like gas passage that atomized through the atomizing air air inlet pipe, enters the nozzle center hole along the nozzle inclined hole again pressure oil atomizing ejection is realized the oil spout preheating.During the water spray coal slurry, the coal slurry inlet valve of fetching boiling water, starting delivery pump and booster pump, water-coal-slurry pumps into nano-bubble generating apparatus by delivery pump, after water-coal-slurry is come out from nano-bubble generating apparatus, become the water-coal-slurry that contains a large amount of nano bubbles, this moment, water-coal-slurry surface can increase and bubble is interior can increase, but strengthening surface oxidation reaction, viscosity reduction simultaneously helps pumping and injection, the nano bubble water-coal-slurry of coming out from nano-bubble generating apparatus enters nozzle center's hole ejection through booster pump pressurization (also can not establish booster pump) after starch pipe, make water-coal-slurry atomizing ejection burning because the nozzle inclined hole is pressed into air simultaneously, can increase substantially efficiency of combustion and reduce the carbon residue discharging and the CO discharging.During termination of pumping, open the scavenging air control valve, the water-coal-slurry in delivery pump, nano-bubble generating apparatus, booster pump, slurry pipe and the nozzle is purged clean.
The utility model compared with prior art, has only increased nano-bubble generating apparatus and booster pump owing to adopt above-mentioned design, and cost increases few, but its efficiency of combustion height, carbon residue is few, and CO content is low, help energy-conserving and environment-protective, the water-coal-slurry viscosity is low simultaneously, helps atomized spray.
