Abstract
The invention discloses a submerged combustion evaporator. The submerged combustion evaporator comprises an evaporation chamber, wherein a material liquid inlet tube and a finished liquid outlet are arranged on the opposite wall of the evaporation chamber; a gas-steam mixture outlet tube is arranged on the upper surface of the evaporation chamber; the submerged combustion evaporator is characterized in that a mixing drum is arranged on the upper surface of the evaporation chamber, wherein a combustion chamber is arranged on the lower surface of the mixing drum; a fuel gas inlet tube, an air inlet tube and an ignition tube are arranged on the upper surface of the mixing drum; the combustion chamber is in the form of a tube; the lower end of the combustion chamber is in the form of a reverse shuttle; the mixing drum is in the form of a reverse water drop; a thermometer tube is further arranged on the wall of the evaporation chamber; the thermometer tube is inserted in the evaporation chamber from the wall surface and is downwards arranged in an inclined manner; and a liquid discharge tube is further arranged at the bottom of the evaporation chamber. The mixing drum can prolong the mixing time of the fuel gas and the air, so that the mixing is uniform, and the combustion is sufficient; simultaneously, air current entering the combustion chamber is more stable.
Description
Technical field
The present invention relates to evaporator with submerged combustion, belong to the chemical industry equipment field.
Background technology
Make the solution boiling vaporization that contains non-volatile solute and shift out steam, thereby make the unit operations that the solute composition improves in the solution be called evaporation, the equipment that is adopted is called evaporimeter.Evaporator with submerged combustion is a kind of not fixing heat-transfer area; The evaporimeter that efficiency of utilization is high, it is that a certain proportion of burner and air are directly sprayed in the solution, the temperature of combustion gas can be up to 1200 ℃-1800 ℃; Because the temperature difference between gas, liquid is big; And gas produces strong bubbling effect to solution, and moisture is evaporated rapidly, and indirect steam that steams and flue gas are together discharged by the top.But the fuel gas of traditional evaporator with submerged combustion mixes in straight tube with air, directly is passed to the combustion chamber by tubule after the mixing, is provided with ignitron at the entry of combustion chamber end; Fuel gas and air also in time do not mix and just are sent to the combustion chamber, and it is thorough to be difficult to burning, causes the wasting of resources; Simultaneously because burning is insufficient; Gas vapour the ingredients of a mixture can become complicacy, and later separation is difficult, simultaneously because burning is insufficient; The temperature of gas does not reach the ideal effect of expection in the spirt material liquid, makes completion liquid not reach requirement.
Summary of the invention
In order to solve the problem of above-mentioned existence, the invention discloses a kind of evaporator with submerged combustion, the present invention can mix fuel gas and air, and during igniting, sufficient combustion makes full use of fuel gas, also can guarantee ignition temperature simultaneously.
Evaporator with submerged combustion; Comprise vaporization chamber; The vaporization chamber relative wall is provided with the material liquid inlet pipe and goes out pipe with completion liquid; Be provided with gas vapour mixture above the vaporization chamber and go out pipe and it is characterized in that being provided with mixing drum above the said vaporization chamber, be provided with the combustion chamber below the mixing drum, be provided with fuel gas inlet pipe, air inlet pipe and ignitron above the mixing drum.
Said combustion chamber in a tubular form, the lower end, combustion chamber is the shape of falling the shuttle.
Said mixing drum is pouring and drips shape.
Also be provided with temperature gauge pipe on the wall of said vaporization chamber, temperature gauge pipe injects vaporization chamber from wall, is tilted to down installation.
Said vaporization chamber bottom also is provided with discharging tube, and discharging tube is provided with straight down.
Fuel gas of the present invention fully mixes in mixing drum with air, and end blows to the material liquid from the combustion chamber for the internal combustion in the combustion chamber, combustion gas, can guarantee the temperature of combustion gas, makes raw material also reach the temperature requirement of expection, and completion liquid is met the requirements.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, further illustrate the present invention.Should understand the following specific embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention.Need to prove; Describe below the word " preceding " that uses, " back ", " left side ", " right side ", " on " and D score refer to the direction in the accompanying drawing, word " interior " and " outward " refer to respectively towards or away from the direction of specific features geometric center.
Fig. 1 is a structural representation of the present invention, from figure, can see, the present invention includes vaporization chamber 1; Vaporization chamber 1 relative wall is provided with material liquid inlet pipe 12 and goes out pipe 8 with completion liquid, is provided with gas vapour mixture above the vaporization chamber 1 and goes out pipe 7, is provided with mixing drum 4 above the vaporization chamber 1; Be provided with combustion chamber 2 below the mixing drum 4, be provided with fuel gas inlet pipe 6, air inlet pipe 5 and ignitron 3 above the mixing drum 4, combustion chamber 2 in a tubular form; 2 lower ends, combustion chamber are the shape of falling the shuttle, and mixing drum 4 is pouring and drips shape, also are provided with temperature gauge pipe 9 on the wall of vaporization chamber 1; Temperature gauge pipe 9 injects vaporization chamber 1 from wall; Be tilted to down installation, vaporization chamber 1 bottom also is provided with discharging tube 10, and discharging tube 10 is provided with straight down.
Fig. 2 is an air-flow sketch map in the mixing drum of the present invention, and mixing drum 4 is the design that pouring drips shape, and fuel gas gets into mixing drum 4; Because air pressure and gas flowing Relationship; Fuel gas can flow towards both sides, and forms eddy current, can prolong and the Air mixing time; Also make simultaneously the air-flow that gets into the combustion chamber more steady, it is more steady that combustion gas gets into material liquid 11.
The disclosed technological means of the present invention program is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technical scheme of being made up of above technical characterictic combination in any.
