Description
Technical field
The utility model relates to a kind of steam atomization spray gun, specifically, relates to a kind of exterior mixing steam atomization spray gun at nozzle exterior, saturated vapor and water being carried out mixing.
Background technology
In prior art, the atomizing lance for coal gas cooling is all internal-mixing.During normal work, need to provide the compressed nitrogen of certain pressure and the water of certain pressure, in the inside of nozzle, compressed nitrogen and water, through the strike of several times, produce very tiny particle simultaneously.After the fine particle after being atomized mixes with coal gas of high temperature, evaporate and take away heat rapidly at short notice, thus reaching the effect reducing temperature and modified coal gas.
Because nozzle is internal-mixing atomization, therefore source of the gas can only be selected compressed nitrogen (coal gas occasion can not select compressed air, easily set off an explosion), and saturated vapor can not be selected, because saturated vapor and press water are when nozzle interior contacts, low-temperature pressure water and saturated vapor carry out heat exchange, saturated vapour pressure can sharply decline, press water cannot be atomized, and from nozzle ejection is the large globule, is not tiny particle.Due to cooling is coal gas, selects compressed air can cause gas explosion as source of the gas, compressed nitrogen therefore can only be selected as source of the gas.To be recovered after blast furnace gas and coal gas dust removal of converter and be recycled, and if select nitrogen as source of the gas, owing to being mixed with nitrogen in coal gas, the calorific value of coal gas can be reduced.And select saturated vapor as the atomization source of the gas of spray gun, after coal gas cooling, the steam in coal gas can be separated out with the form of aqueous water, can not affect concentration and the calorific value of coal gas.But internal-mixing atomizing lance of the prior art selects saturated vapor cannot realize atomization as source of the gas.For this problem, be necessary to improve existing atomizing lance.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of steam atomization spray gun, and it can solve existing internal-mixing atomizing lance and saturated vapor cannot be selected as the problem of source of the gas.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of steam atomization spray gun, wherein, comprise inside pipeline and be sheathed on the outside pipeline of described inside pipeline outside, the first end of described inside pipeline and described outside pipeline is connected with end socket, the second end is connected with nozzle, is formed with hollow region between described inside pipeline and described outside pipeline; Described end socket is connected with the water inlet pipe be connected with described inside pipeline, described outside pipeline is connected with the saturated vapor input pipe communicated with described hollow region, described inside pipeline includes the second stainless steel pipeline section that the first stainless steel pipeline section of connecting with described end socket connects with described nozzle and the metal hose section be connected between described first stainless steel pipeline section and described second stainless steel pipeline section.
Further, the second straight length that described water inlet pipe comprises the first straight length connected with described end socket, the elbow connected with described first straight length and connects with described elbow, the outer surface of described second straight length offers screw thread.
Further, described saturated vapor input pipe comprises the Taper Pipe section be connected with described outside pipeline and the 3rd straight length be connected with described Taper Pipe section, and the outer surface of described 3rd straight length offers external screw thread.
Further, the external stability of described outside pipeline has locking flange.
Further, described metal hose section is welding type metallic flexible tube section.
Adopt steam atomization spray gun of the present utility model, there is following beneficial effect: outside pipeline and inside pipeline are set, at nozzle exterior saturated vapor and water high velocity impact, current are knocked into tiny droplet, achieve the object with saturated vapor atomizing pressure water, make the water droplet particle after being atomized meet D32=100-200um, thus meet the cooling requirement of coal gas.Meanwhile, steam can also externally side ducts cool, and prevents it from destroying by coal gas high-temperature.In addition, the part in the middle of inside pipeline selects metal hose, can prevent spray gun from causing distortion by high temperature.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of steam atomization spray gun of the present utility model;
Fig. 2 is that schematic diagram is looked on a left side of Fig. 1.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment and accompanying drawing, the utility model is further described.
The utility model discloses a kind of steam atomization spray gun, this steam atomization spray gun can mix with water saturated vapor at nozzle exterior, thus makes it be atomized, and lowers the temperature to coal gas.
See Fig. 1, Fig. 2, steam atomization spray gun of the present utility model, comprises inside pipeline 2 and is sheathed on the outside pipeline 3 of inside pipeline 2 outside.Inside pipeline 2 is connected with end socket 5 with the first end (left end in Fig. 1) of outside pipeline 3, the second end (right-hand member in Fig. 1) is connected with nozzle 1, is formed with hollow region (not indicating in figure) between inside pipeline 2 and outside pipeline 3.End socket 5 is connected with the water inlet pipe 6 be connected with inside pipeline 2, to be introduced into by water in inside pipeline 2; Outside pipeline 3 is connected with the saturated vapor input pipe 7 communicated with hollow region, saturated vapor is introduced into hollow region, afterwards, water and saturated vapor accelerate by the spiral of nozzle 1 internal structure, at nozzle exterior high velocity impact, and formation D
32the particle of=100-200um, dispels the heat to coal gas.This mode, not only meet the cooling of converter dry dedusting coal gas to the requirement of cooling water droplet, ensure that water droplet evaporates completely within the limited time, do not occur wetting the problem of wall in the wet end, and the steam after cooling in coal gas is separated out with the form of the water of liquid state, can not affect the composition of coal gas.
