The technical scheme of the utility model is that: a jet-suction type flat spray gun comprises an air inlet pipe, a sleeve, a front flange, a sealing gasket, a bolt nut, a support, a water inlet pipe, a rear flange and a spray head;

the sleeve is welded and fixed with the outer wall of the air inlet pipe, an inlet at one end of the air inlet pipe is arranged outside the sleeve, and an outlet at the other end of the air inlet pipe is arranged in the sleeve;

the water inlet pipe is welded and fixed with the sleeve, and the inside of the water inlet pipe is communicated with the inner cavity of the sleeve;

the outer wall of the sleeve is welded and fixed with the front flange;

the support welded fastening is in sheathed tube outer wall, back flange welded fastening in the outside of support, preceding flange and back flange pass through bolt and nut and connect fixedly, preceding flange and back flange between set up sealed pad sealed.

Further, the inlet tube level set up, intake pipe slope set up, inlet tube center pin be 30 with the contained angle of intake pipe center pin.

Furthermore, the vertical section of the nozzle of the spray head is rectangular.

Furthermore, the spray heads are flat and are symmetrically arranged in a mutually inclined manner, and the included angle between the upper surface and the lower surface of each spray head is 30 degrees.

The utility model has the advantages that: the inner structure is of a jet-suction type, the shape of spray is flat, and the spray has a good effect of removing fine dust in smoke. The gas and liquid pressure of the spray gun can be bidirectionally adjusted without interference, and the liquid pressure: 0.5 bar-10 bar, gas pressure: 1.5 bar-10 bar, the regulation ratio can reach 1: 8, forming water mist particles of about 50-120 microns, and separating the water mist particles from the smoke after scaling with fine dust in the smoke so as to achieve the best effect and purpose of dust removal.

The utility model discloses coefficient of heat transfer is high, the impact force increases, adopts to penetrate and inhale formula structure, can the flash mixed evaporation and take away the heat, carries out quenching and tempering to the flue gas simultaneously, makes the temperature fall rapidly to the target value, and the inner passage is unblocked not to have blockked up, and pressure increases and guarantees that dust removal process goes on smoothly, does not have the spiral and spouts the core and spout the seat and do not need regular cleaning, can use various industrial water and turbid circulating water to practice thrift manufacturing cost.
