Abstract
The utility model relates to a fire-proof air-regulating pipeline which comprises a main pipeline (1). A regulating valve (2) and a fire-proof cover (5) are arranged on the main pipeline (1), wherein the regulating valve (2) is connected below the main pipeline (1), the fire-proof cover (5) is located at the front of the regulating valve (2) and the fire-proof cover (5) is communicated with the main pipeline (1). The fireproof cover (5) can be divided into a settling chamber (5.1) and a gathering chamber (5.2) from top to bottom. A plurality of blocking plates are arranged in the settling chamber (5.1). Dust and smoke enter the settling chamber (5.1) from the front of the settling chamber (5.1). A certain angle exists between the direction of the plurality of the blocking plates (6) and the direction of the dust and the smoke. The lower portion of the regulating valve (2) is rightly opposite to a smoking mouth (4). The smoking mouth (4) is connected with a smoking cover (3). The regulating valve (2) is connected with an electrical appliance control system on the ground. Air quantity can be regulated through the electrical appliance control system. The fire-proof air-regulating pipeline can be used for lowering the temperature of the dust and the smoke. A bag-type dust remover can be prevented from being damaged by the Mars. The fire-proof air-regulating pipeline can be used for prolonging the service life. In addition, the electrical appliance control system can be used for conveniently controlling the regulating valve so as to achieve an energy-saving purpose. Production cost can be reduced.
Description
Technical field
The utility model relates to a kind of anti-thermal transfer wind pipeline.
Background technology
Medium frequency or electric furnace inevitably produce dust and flue gas in the process of using, medium frequency or electric stove dust are exactly that the dust in medium frequency or electric furnace is separated from flue gas, thereby reduce dust pollution and be conducive to further flue gas be carried out the processing such as desulphurization and denitration.Along with the development of society, people's attention is more and more received in environmental protection, and medium frequency or electric stove dust also have been applied to the every field such as thermal power generation.But the dust that produces in medium frequency or electric furnace and flue gas have very high temperature, also with Mars, flash back after sack cleaner bad or damage cloth bag if directly enter in pipeline, and changing cloth bag not only labor intensive and time, and maintenance cost is high and difficulty is large; The temperature of dust and flue gas can be reduced by increasing the flue diameter in addition, but cost can be increased, and easy dust stratification, the waste of material caused.
Simultaneously, the exhaust gas volumn that medium frequency or electric furnace produce is different, simultaneously due to smoking effect before and after pipeline and smoking negative pressure difference, so the temperature of fire door and exhaust gas volumn will be different at different times, so just namely can not control the exhaust gas volumn of every medium frequency or electric furnace, can increase electric weight, cause waste, increase production cost.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of anti-thermal transfer wind pipeline that can regulate air quantity and remove Mars in flue gas is provided.
The purpose of this utility model is achieved in that
A kind of anti-thermal transfer wind pipeline comprises trunk line, and described trunk line is provided with control valve and flameproof enclosure, and wherein control valve is connected to trunk line below, and flameproof enclosure is positioned at control valve the place ahead, and is communicated with trunk line; Described flameproof enclosure is divided into expansion chamber and collecting chamber from top to bottom, is provided with the polylith baffle plate in described expansion chamber, and dust and flue gas enter from the place ahead of expansion chamber, the setting party of described polylith baffle plate to the direction of dust and flue gas with certain angle; Described control valve aligned beneath smoking port, smoking port is connected with range hood; Described control valve is connected with the electrical apparatus control system on ground, regulates the size of air quantity by electrical apparatus control system.
The utility model is prevented the thermal transfer wind pipeline, and the cross section of described control valve is square or circular.
Compared with prior art, the beneficial effects of the utility model are:
The anti-thermal transfer wind pipeline of the utility model can reduce the temperature of dust and flue gas, prevents that Mars from causing damage to sack cleaner, can increase the service life; Control to adjust valve by electrical apparatus control system in addition very convenient, reach energy-conservation purpose, reduced production cost.
Description of drawings
Fig. 1 is the structural representation of the anti-thermal transfer wind pipeline of the utility model.
Wherein:
Trunk line 1
Smoking port 4
Expansion chamber 5.1
Collecting chamber 5.2
Baffle plate 6.
The specific embodiment
Referring to Fig. 1, the utility model is prevented the thermal transfer wind pipeline, comprises trunk line 1, and described trunk line 1 is provided with control valve 2 and flameproof enclosure 5, and wherein control valve 2 is connected to trunk line 1 below, and flameproof enclosure 5 is positioned at control valve 2 the place aheads, and is communicated with trunk line 1.
Described flameproof enclosure 5 is divided into expansion chamber 5.1 and collecting chamber 5.2 from top to bottom, is provided with polylith baffle plate 6 in described expansion chamber 2, and dust and flue gas enter from the place ahead of expansion chamber 5.1, the setting party of described polylith baffle plate 6 to the direction of dust and flue gas with certain angle.
Described control valve 2 aligned beneath smoking ports 4, smoking port 4 is connected with range hood 3.Described control valve 2 is connected with the electrical apparatus control system on ground, regulates the size of air quantity by electrical apparatus control system, and the cross section of described control valve 2 is square or circular.
After dust and flue gas entered expansion chamber 5.1 from trunk line 1, dust and Mars collided to take advantage of a situation to fall after baffle plate 6 and enter collecting chamber 5.2, because expansion chamber 5.1 height are higher than trunk line 1, so flue gas has also obtained cooling in expansion chamber 5.1.After cooling and the flue gas of removing Mars enter after sack cleaner just safelyr from trunk line 1, can not cause the damage of cloth bag, then flue gas is regulated air quantity by the control valve 2 at rear again.It is very convenient that electrical apparatus control system controls to adjust valve 2, and the adjusting by control valve 2 air quantity reaches energy-conservation purpose, has reduced production cost.
