Abstract
The invention relates to a magnetization coal powder spraying-blowing apparatus, which comprises a spraying pipe and a connection pipe, wherein one end of the connection pipe is connected with the spraying pipe through a valve, and the other end of the connection pipe is connected with a coal powder conveying pipeline. The magnetization coal powder spraying-blowing apparatus is characterized in that the outer portion of the connection pipe is sleeved with a permanent magnet sheath, the outer portion of the permanent magnet sheath is wrapped with a layer of a permanent magnet protection sleeve, the connection pipe is a stainless steel connection pipe, and the permanent magnet protection sleeve is a plastic permanent magnet protection sleeve. According to the invention, the permanent magnet sheath is arranged on the connection pipe position to magnetize coal powder passing through the connection pipe so as to achieve reduce a coal powder burning point effect, completely burn coal powder in a blast furnace, achieve blast furnace coke consumption reduction, and promote energy saving and emission reduction of enterprises.
Description
Technical field
The present invention relates to a kind of coal powder blowing device, specifically a kind of magnetization coal injection device.
Background technology
All need to carry out coal injection at metallurgy industry and Thermal Power Generation Industry, the ironmaking system of metallurgy industry particularly, need in the process of carrying out smelting iron and steel to coal injection in blast furnace, to reduce the higher coke usage quantity of price, thereby boost productivity and reduce production costs.At present, the coal dust of blast furnace blowing, and what adopt is hard coal,, because the hard coal burning-point is higher, often in winding-up, can not fully promptly burn to time in blast furnace, has caused the waste of the energy, is unfavorable for the energy-saving and emission-reduction of enterprise.
Nearest research shows, after being magnetized, pulverized anthracite can reduce the burning-point of coal dust, make can fully burning of coal dust, based on above-mentioned achievement in research, developing a kind of coal injection device that magnetizes becomes the present problem that solves that needs with the usage quantity of further saving coke.
Summary of the invention
Technical problem solved by the invention has been to provide a kind of magnetization coal injection device, it overcomes winding-up and enters the inadequate deficiency of coal dust firing in blast furnace, this device sprays in blast furnace after coal dust is magnetized, make the Coal Powder Ignition Point that enters in blast furnace reduce, burn more abundant, thereby realized reducing the purpose that blast furnace fuel consumes.
For solving the problems of the technologies described above; a kind of magnetization coal injection of the present invention device; comprise jet pipe and pipe connecting; one end of described pipe connecting is connected in jet pipe by valve; the other end of described pipe connecting connects the coal dust transfer line; it is characterized in that, the outer cover of described pipe connecting is equipped with the permanent magnet sleeve pipe, outer wrap one deck permanent magnet protective sleeve of permanent magnet sleeve pipe.
Described pipe connecting is the stainless steel pipe connecting.
The permanent magnet protective sleeve that described permanent magnet protective sleeve is plastic material.
The invention has the beneficial effects as follows: a kind of coal injection device that magnetizes of this invention is by arranging the mode of permanent magnet sleeve pipe at the pipe connecting place, to magnetize through the coal dust at pipe connecting place, thereby reach the effect that reduces Coal Powder Ignition Point, make coal dust more abundant in the blast furnace internal combustion, reduce like this blast-furnace coke consumption, can effectively reduce the waste of resource, improved the utilization ratio of the energy, and improved to a certain extent the economic benefit of blast furnace, significant for the energy-saving and emission-reduction of promoting enterprise.
Description of drawings
Fig. 1 is control principle block diagram of the present invention;
In figure: 1-jet pipe, 2-pipe connecting, 3-valve, 4-coal dust transfer line, 5-permanent magnet sleeve pipe, 6-permanent magnet protective sleeve.
Embodiment
, for clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
As shown in Figure 1; a kind of magnetization coal injection of the present invention device; it comprises jet pipe 1 and pipe connecting 2; one end of described pipe connecting 2 is connected in jet pipe 1 by valve 3; the other end of described pipe connecting 2 connects coal dust transfer line 4; the outer cover of described pipe connecting 2 is equipped with permanent magnet sleeve pipe 5, outer wrap one deck permanent magnet protective sleeve 6 of permanent magnet sleeve pipe 5.
Described pipe connecting 2 is the stainless steel pipe connecting.Permanent magnet sleeve pipe 5 can closely be pulled on pipe connecting 2 like this, and permanent magnet sleeve pipe 5 can magnetize pipe connecting 2, thereby reaches the magnetized effect of coal dust through pipe connecting 2.
Described permanent magnet protective sleeve 6 is the permanent magnet protective sleeve of plastic material.Permanent magnet protective sleeve 6 is mainly that permanent magnet sleeve pipe 5 is protected, and also can reduce to a certain extent the interference of extraneous factor for permanent magnet sleeve pipe 5 on the other hand, guarantees the magnetization effect that permanent magnet sleeve pipe 5 is good.
During use, coal dust enters pipe connecting 2 through coal dust transfer line 4, after magnetize at pipe connecting 2 places, sprinkling enters in blast furnace, can reduce the burning-point of coal dust like this, make the coal dust can perfect combustion in blast furnace, for the energy-saving and emission-reduction that realize enterprise, have good effect.
Except the described technical characterictic of above-mentioned specification sheets, be the known technology of those skilled in the art.
