A hollow zone is formed between the inner-side pipeline and the outer-side pipeline. The end socket is connected with a water input pipe which communicates with the inner-side pipeline. A nitrogen input pipe communicating with the hollow zone is arranged on the outer-side pipeline. The inner-side pipeline comprises a first stainless steel pipeline section connected with the end socket, a second stainless steel pipeline section connected with the nozzle, and a metal flexible pipeline section connected between the first stainless steel pipeline section and the second stainless steel pipeline section. By the adoption of the steam atomizing spray gun, steam and water can be mixed to produce mist which cools coal gas.

Description

Steam atomization spray gun
Technical field
The present invention relates to a kind of steam atomization spray gun, it particularly relates to a kind of exterior mixing steam atomization spray gun being undertaken saturated vapor and water at nozzle exterior mixing.
Background technology
In prior art, the atomizing lance for coal gas cooling is all internal-mixing. During normal operation, it is necessary to provide the compressed nitrogen of certain pressure and the water of certain pressure, in the inside of nozzle simultaneously, compressed nitrogen and water, through the strike of several times, produce very tiny granule. After the fine particle after being atomized mixes with coal gas of high temperature, evaporate rapidly at short notice and take away heat, thus reducing temperature and the effect of modified coal gas.
Owing to nozzle is internal-mixing atomization, therefore source of the gas can only select compressed nitrogen (coal gas occasion can not select compression air, easily caused by blast), and saturated vapor can not be selected because saturated vapor with press water 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 big globule, is not tiny granule. Due to cooling is coal gas, selects compression 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 and recycled after blast furnace gas and coal gas dust removal of converter, if selecting nitrogen as source of the gas, owing to coal gas being mixed with nitrogen, 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 precipitate out with the form of aqueous water, without influence on 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, it is necessary to existing atomizing lance is improved.
Summary of the invention
The technical problem to be solved in the present invention is in that, it is provided that a kind of steam atomization spray gun, it can solve the problem that existing internal-mixing atomizing lance cannot select saturated vapor as the problem of source of the gas.
For solving above-mentioned technical problem, the technical solution used in the present invention is in that: a kind of steam atomization spray gun, wherein, including inside pipeline and be sheathed on the outside pipeline outside described inside pipeline, the first end of described inside pipeline and described outside pipeline is connected to end socket, the second end is connected to nozzle, is formed with hollow region between described inside pipeline and described outside pipeline; Described end socket is connected to the water inlet pipe being connected with described inside pipeline, being connected to the saturated vapor input pipe communicated with described hollow region on the pipeline of described outside, described inside pipeline includes the second rustless steel pipeline section that the first rustless steel pipeline section connected with described end socket connects with described nozzle and is connected to the metal hose section between described first rustless steel pipeline section and described second rustless steel pipeline section.
Further, elbow that the first straight length that described water inlet pipe includes connecting with described end socket connects with described first straight length and the second straight length connected with described elbow, the outer surface of described second straight length offers screw thread.
Further, described saturated vapor input pipe includes the Taper Pipe section being connected with described outside pipeline and the 3rd straight length being 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 the steam atomization spray gun of the present invention, have the advantages that and outside pipeline and inside pipeline are set, at nozzle exterior saturated vapor and water high velocity impact, current are knocked into tiny droplet, achieve by the purpose of saturated vapor atomizing pressure water, the water droplet granule after atomization is made to meet D32=100-200um, thus meeting the cooling requirement of coal gas. Meanwhile, steam can also externally side ducts cool down, it is prevented that it is destroyed by coal gas high-temperature. Additionally, the part in the middle of inside pipeline selects metal hose, it is possible to prevent spray gun from being caused deformation by high temperature.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the structural representation of the steam atomization spray gun of the present invention;
Fig. 2 is the left view schematic diagram of Fig. 1.
Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with embodiment and accompanying drawing, the present invention is described in more detail.
The invention discloses a kind of steam atomization spray gun, saturated vapor can be mixed with water by this steam atomization spray gun at nozzle exterior, so that its atomization, coal gas is lowered the temperature.
Referring to Fig. 1, Fig. 2, the steam atomization spray gun of the present invention, including inside pipeline 2 and be sheathed on the outside pipeline 3 outside inside pipeline 2. The first end (left end in Fig. 1) of inside pipeline 2 and outside pipeline 3 is connected to end socket 5, the second end (right-hand member in Fig. 1) is connected to nozzle 1, is formed with hollow region (not indicating in figure) between inside pipeline 2 and outside pipeline 3. End socket 5 is connected to the water inlet pipe 6 being connected with inside pipeline 2, in order to introduce the water into inside pipeline 2; Being connected to, on the pipeline 3 of outside, the saturated vapor input pipe 7 communicated with hollow region, in order to introduce saturated vapor to hollow region, afterwards, water and saturated vapor accelerate by the spiral of nozzle 1 internal structure, at nozzle exterior high velocity impact, formation D32The granule of=100-200um, dispels the heat to coal gas. This mode, not only meet the converter dry dedusting coal gas cooling requirement to cooling water droplet, it is ensured that water droplet evaporates completely within the limited time, the problem occurring without the wet wall in the wet end, and the steam in coal gas precipitates out with the form of the water of liquid after lowering the temperature, without influence on the composition of coal gas.
In Fig. 1, inside pipeline 2 includes three sections, specifically, the second rustless steel pipeline section 203 of connecting with nozzle 1 of the first rustless steel pipeline section 201 connected with end socket 5 and be connected to the metal hose section 202 between the first rustless steel pipeline section 201 and the second rustless steel pipeline section 203. The effect of metal hose section 202 is, it is to avoid spray gun is affected by coal gas of high temperature and causes deformation.
