Abstract

The method relates to a method for heating zinc pot of galvanizing equipment with large scale. A heating burning chamber is set on two ends of the galvanizing zinc pot, heat amount discharged by the burning chamber communicates in a heating channel on two sides of the zinc pot, the heating channel is disconnected into two parts in a middle segment of the zinc pot, an interface communicated with a smoke channel is set on the disconnecting part. Multi-stage burner nozzles are set in the burning chamber from upper to down, an air flow support device is set on frond end of the burner nozzle on the most bottom for supporting writhing the heat flow generated from the burning chamber. The burning chamber is set on two ends of the zinc pot which leads to no firewall be required, and the zinc pot does not contact with bright fire basically for prolonging working life of the zinc pot, at the same time, the heat amount does not loss in heat conducting process, a structure with two segments is convenient for hot air flowing; in addition, a hot flow support wall outside the burning chamber can make the hot air flowing with method of writhing, accordingly, the heat discharge is more sufficient. Compared with an experiment result, the galvanizing equipment has one third energy consumption of a traditional method.

Description

The method for heating zinc pot of galvanizing equipment with large scale
Technical field
The present invention relates to the zinc liquor heating method of galvanizing equipment, specifically, relate to a kind of main equipment, large-scale steel pipe for example, when carrying out zinc-plated operation, the method that the zinc liquid in the zinc pot is heated.
Background technology
Pot galvanize is a kind of very common industrial means, and the steel piece after zinc-plated can not be corroded in the long time, and aesthetic measure also improves greatly.In galvanized process, especially large-scale workpiece is carried out normally utilizing when zinc-plated tun splendid attire zinc liquid, and container is continued heating, at high temperature unplated piece is put into container and carried out zinc-plated operation.In whole process, it is an important factors that zinc liquid is kept constant temperature.The present container that holds zinc liquid is generally the zinc pot of 50 millimeters of wall thickness, when zinc-plated, utilizes a plurality of boccas that are arranged on zinc pot sidewall simultaneously it to be heated.The rate of heating ratio of this type of heating is very fast, still directly is sprayed onto for fear of flame on the zinc pot this to be caused damage, so need set up fireproof brickwork between bocca at the zinc pot, so will cause the part of heat to run off.Take this type of heating also very big in addition, do not meet the trend and the requirement of current energy-saving and emission-reduction, and cause the raising greatly of production cost for the demand of energy.。
Summary of the invention
It is big to the objective of the invention is to the power consumption that exists at existing zinc-plated heating means, and deficiency such as at the bottom of the Btu utilization provides a kind of heating means of galvanizing equipment with large scale.
Technical scheme of the present invention is: a kind of method for heating zinc pot of galvanizing equipment with large scale, the heating flame chamber is arranged at two ends of zinc-plated zinc pot, the combustion chamber liberated heat circulated in adding in the thermal pit hole of zinc pot both sides, to add the thermal pit hole in the stage casing of zinc pot and block and be two portions, and offer the interface that communicates with flue in the truncated position.
Preferably, set up multistage bocca in the combustion chamber from top to bottom, at the front end of the bocca of bottommost air-flow is set and lifts device, the hot gas flow that makes the combustion chamber produce is lifted to seethe.
Preferably, described air-flow is lifted device for being arranged on bocca the place ahead firebreak, and the height of firebreak is not higher than the set height of bottommost bocca.
Preferably, temperature monitoring apparatus is set, and controlled air door, the switching of the temperature control air door of the smoke outlet that monitors according to temperature monitoring apparatus in the exit of flue.
Preferably, utilize described temperature monitoring apparatus and controlled air door, the temperature of smoke outlet is controlled at 500 ℃-600 ℃.
Beneficial effect of the present invention is: owing to the combustion chamber is arranged at the two ends of zinc pot, therefore need not to be provided with again fireproof brickwork, and the basic flames of anger contacts with the zinc pot, prolonged the work-ing life of zinc pot, simultaneously, loss can not appear in heat in conductive process, and takes the structure of two-part, is convenient to flowing of warm air; In addition, the hot gas flow outside the combustion chamber is lifted wall can make warm air flow in the mode of rolling, thereby heat release is more abundant, and according to experimental result relatively, the power consumption of this galvanizing rig only is 1/3rd of a traditional way.

Fig. 2 is the A-A cross-sectional view of the specific embodiment of the invention;
Fig. 3 is the B-B cross-sectional view of the specific embodiment of the invention.
Embodiment
Specific embodiments of the invention as shown in Figure 1 to Figure 3, a kind of method for heating zinc pot of galvanizing equipment with large scale, this galvanizing rig comprises a zinc pot 2 that is loaded with zinc liquid, and the heating unit that is coated on zinc pot 2 peripheries, described heating unit is a heating stove 1, in heating stove 1, two sides of zinc pot 2 have respectively and add thermal pit hole 8 together, heating flame chamber 4 is arranged at two ends of zinc-plated zinc pot 2, combustion chamber 4 liberated heats are in the circulation in the thermal pit hole 8 that adds of zinc pot 2 both sides, be provided with between the inwall of zinc pot 2 and heating stove 1 and support fore-set 6, and the outside surface of zinc pot 2 is welded with the bracing frame of V-arrangement, and ramming mass 7 is that skeleton waters the outside surface that overlays on zinc pot 2 with the bracing frame.To add thermal pit hole 8 in the stage casing of zinc pot 2 and block and be two portions, and offer the interface that communicates with flue 5 in the truncated position.Set up multistage bocca 3 in the combustion chamber from top to bottom, at the front end of the bocca 3 of bottommost air-flow is set and lifts device, the hot gas flow that makes the combustion chamber produce is lifted to seethe.It is the firebreak 9 that is arranged on bocca the place ahead that described air-flow is lifted device, and the height of this firebreak 9 is not higher than the set height of bottommost bocca.Exit at flue 5 is provided with temperature monitoring apparatus, and controlled air door, the switching of the temperature control air door of the smoke outlet that monitors according to temperature monitoring apparatus.Utilize described temperature monitoring apparatus and controlled air door, the temperature of smoke outlet is controlled at 500 ℃-600 ℃.
During work, inflammable gas in the bocca 3 takes fire and the evolution of heat, hot gas flow stops during by firebreak 9 to be lifted, form an air-flow that makes progress, have influence on multiple tracks hot gas flow from top to bottom simultaneously, in this process, heat is discharged fully, and beginning is flowed in adding thermal pit hole 8, temperature monitoring apparatus is monitored the temperature of spout in process of flowing, if temperature is too high, then closes ventilation opening, the velocity of flow of hot gas flow is slowed down, heat further fully discharges, if the spout temperature is lower, then opens ventilation opening, hot gas flow is flowed improve, as early as possible heating.
