Abstract
The utility model provides a metal burner for preparing methanol synthesis gas. A cooling water inlet and a cooling water outlet which are communicated with the interior of a burner body are formed at the lateral wall of the burner body; a protective steam inlet communicated with the interior of the burner body is also arranged at the lateral wall of the burner body; an oxygen/steam inlet is arranged at the inlet end of the burner body; a protecting sleeve is arranged on the part, extending inside the furnace, of the burner body; a gas distributer is arranged at the front end of the head part of the burner body; and the gas distributor and the burner body are fixed through a diagonal stay rib. By adopting the metal burner, unplanned parking of a converting process system is effectively avoided, so that the metal burner can safely and reliably run for a period of time; and the service life of the metal burner is prolonged.
Description
Technical field
The utility model relates to the pure oxygen metal burner that uses when the preparation methyl methanol syngas.
Background technology
Methyl alcohol is except synthetic ammonia, and unique chemical of being reformed and synthesizing on a large scale through gasification and natural gas via by coal is important carbonizer's basic product and an Organic Chemicals.The raw material of methyl alcohol synthetic technology has multiple, as Sweet natural gas, coke-oven gas, and coal, coal-seam gas, crude oil, heavy oil, tar etc., thereby the producing gas method of its raw material and operational path also vary.
Be the methanol conversion process processed of raw material with Sweet natural gas and coke-oven gas, its synthetic gas (H
2, CO and CO
2) the nucleus equipment of preparation all be burner.Domestic early stage converter adopts heat-resisting mould material mostly, burner all adopts corundum brick to pile up and forms, unstripped gas (Sweet natural gas or coke(oven)gas etc.) is inhomogeneous with oxygen mix, fuel medium local burning in stove often appears, situations such as the interior refractory castable of scaling loss corundum brick burner and stove, the frequent passive parking of enterprise, the maintenance converter, bring hidden danger to safety and production, the converter of scaling loss needs again mould material or corundum brick to be changed simultaneously, maintenance cycle is long, causes the business economic benefit impaired.
Summary of the invention
The purpose of this utility model provides a kind of metal burner for methyl methanol syngas processed, makes the combustion high temperature district break away from the burner head, avoids that burner is carried head and burns out, and has prolonged burner work-ing life.
The technical solution of the utility model is: a kind of metal burner for methyl methanol syngas processed; it is characterized in that being provided with cooling water inlet and the cooling water outlet that feeds burner body inside at the burner body sidewall; on the burner body sidewall, also be provided with the protection steam-in that feeds burner body inside; be provided with oxygen/steam-in at burner body inlet end; stretch into furnace interior at the burner body and be arranged with protection sleeve; be provided with gas distributor in burner body head front position, gas distributor and burner body are fixed by tiltedly drawing rib.
Stuffed heat insulated cotton in protection sleeve wherein.
Be provided with burner and body of heater joint flange at the burner body.
The cooling water inlet is connected with the cooling water outlet flange by the cooling water inlet flange with the burner body sidewall with cooling water outlet.
The protection steam-in is connected by protection steam-in flange with the burner body sidewall.
Oxygen/steam-in is connected by oxygen/steam-in flange with the burner body.
The utility model can mix oxygen by the metal burner effectively uniformly with unstripped gas (Sweet natural gas or coke(oven)gas etc.), fuel medium concentrates on the burning of metal burner shower nozzle leading portion centre, make the combustion high temperature district break away from the burner head, avoid burner body head is burnt out, prolonged burner work-ing life.

Embodiment
As shown in Figure 1; the utility model metal burner comprises: oxygen/steam-in flange 1, protection steam-in flange 2, cooling water inlet flange 3; cooling water outlet flange 4; burner and body of heater joint flange 5, protection sleeve 6, heat insulation foam 7; tiltedly draw rib 8; gas distributor 9, burner body 10, coke(oven)gas/gas inlet 11.
Be provided with cooling water inlet and the cooling water outlet that feeds burner body inside at burner body 10 sidewalls; on burner body 10 sidewalls, also be provided with the protection steam-in that feeds burner body inside; be provided with oxygen/steam-in at burner body 10 inlet ends; stretch into furnace interior at burner body 10 and be arranged with protection sleeve 6; be provided with gas distributor 9 in burner body 10 head front positions, gas distributor 9 and burner body 10 are by tiltedly drawing rib 8 fixing.
As shown in Figure 2, oxygen/steam-in changes into by metal burner inlet end vertical centre axis direction and spraying in the stove, and coke(oven)gas/steam maintenance level sprays into constant along stove internal tangent direction.
Oxygen/steam through preheating enters converter combustion space 12 by oxygen/steam-in by the oxygen burner that heat-resisting mould material and corundum brick are built into, spray into the burning rapidly of 12 backs, combustion space with the coke(oven)gas/steam after being heated to about 660 ℃ by coke(oven)gas/steam-in, gas temperature after the burning can reach more than 1400 ℃, gas carries out conversion reaction by nickel Catalytic Layer 13, removes synthetic ammonia or methyl alcohol through the reforming gas after the conversion reaction by reforming gas outlet 14.Oxygen/steam enters in the stove by the oxygen burner, high-temperature coke furnace gas (Sweet natural gas) burning after moment and the preheating.
The utility model metal burner has changed the shortcoming that oxygen burner combustion flame that former heat-resisting mould material and corundum brick be built into burns near the stove inwall, oxygen combustion flame is concentrated in the burner hearth on the vertical center line, like this with regard to having avoided the high-temperature zone with heat-resisting mould material and the frequent scaling loss of corundum brick and cause the passive parking of converter to bring financial loss to enterprise.
As shown in Figure 2, simultaneously for guarantee pure oxygen metal burner can be in the furnace flame high-temperature zone about 1700 ℃ long-time safe and stable operations, pure oxygen metal burner has been carried out the cooling water circulation design of burner, the cooling water inlet is connected with cooling water outlet flange 4 by cooling water inlet flange 3 with burner body 10 sidewalls with cooling water outlet, utilizes water coolant that the heat of burner outer wall and head is taken away.
As shown in Figure 2, increase protection sleeve 6 and the heat insulation foam of being made by high temperature alloy 7 at the burner external surface simultaneously, farthest protected pure oxygen metal burner can avoid furnace high-temperature for the influence of burner safe and stable operation.
As shown in Figure 2; protect the steam-in to be connected by protection steam-in flange 2 with burner body 10 sidewalls simultaneously; formed one tunnel protection vapour passage; utilize steam to avoid the oxygen combustion flame instability that in start-stop car process, brings during load variations when pure oxygen metal burner and the phenomenon of the tempering ablation pure oxygen metal burner head that causes, thereby prolong pure oxygen metal burner work-ing life.
