Description
Technical field
The utility model relates to one wind control device, particularly relates to a kind of rotary kiln burning wind control device, belongs to solid waste disposal technical field.
Background technology
The production process of rotary kiln it is crucial that the degree of automatically control and level, this be related to rotary kiln can realize under equal working condition high conversion, kiln steady running, stop hazardous emission and coal gas energy consumption height. In the production process of rotary kiln, it is achieved energy-saving and emission-reduction and to improve transformation efficiency be that the target pursued produced by rotary kiln, wherein particularly important is the Reasonable Combustion of coal gas, enable is fully used. But in actual production, owing to caloric power of gas fluctuation, pressure transient, air-fuel ratio set the reasons such as unreasonable, often cause the problems such as kiln temperature fluctuation is big, low conversion rate, energy consumption increase.
Practical novel content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art, the utility model provides a kind of rotary kiln burning wind control device, it is possible to total ventilation in control rotary kiln, reduces wind speed in kiln, improve oxygen level in kiln, accelerate the decomposition rate of material.
For achieving the above object, the technical solution adopted in the utility model is: a kind of rotary kiln burning wind control device, comprises housing, frequency conversion tank, the oxygen analyser being connected respectively, negative pressure transmitter and the induced draft fan being connected with frequency conversion tank respectively, gas blower with housing; Described induced draft fan and gas blower outlet air end are connected with rotary kiln by connecting tube; Described frequency conversion tank and housing are connected by control line; Described oxygen analyser is connected to the top of rotary kiln by pipeline; Described negative pressure transmitter is connected to the side of described rotary kiln by breather line.
Improving further as the utility model, described induced draft fan is connected with rotary kiln smoke outlet;Described gas blower is connected with the blast inlet of rotary kiln.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantage:
Rotary kiln burning wind control device of the present utility model, when rotary kiln steady operation, in real time negative pressure in detection kiln, flue gas oxygen content, to parameters such as coal/powder-feeding amount, drum/induced draft fan rotating speeds, by frequency conversion tank, housing control drum/induced draft fan, realize air and the coal gas automatic mixing of rotary kiln, to reach energy-saving and emission-reduction; When pressure changes, after negative pressure transmitters sense, change kiln inner pressure by frequency conversion, kiln temperature deviation is controlled in the scope of ± 5 DEG C, reduce gas consumption 3%, bring considerable economic benefit.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of rotary kiln burning wind control device of the present utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Described in the utility model a kind of rotary kiln burning wind control device as shown in Figure 1, comprises housing 1, frequency conversion tank 2, the oxygen analyser 3 being connected respectively, negative pressure transmitter 4 and the induced draft fan 5 being connected with frequency conversion tank 2 respectively, gas blower 6 with housing 2; Described induced draft fan 5 and gas blower 6 outlet air end are connected with rotary kiln 7 by connecting tube; Described frequency conversion tank 2 and housing 1 are connected by control line 8; Described oxygen analyser 3 is connected to the top of rotary kiln 7 by pipeline 9; Described negative pressure transmitter 4 is connected to the side of described rotary kiln 7 by breather line 10.
Described induced draft fan 5 is connected with rotary kiln smoke outlet; Described gas blower 6 is connected with the blast inlet of rotary kiln.
Oxygen analyser 3 can detect oxygen level in kiln in real time, thus controls the dynamic proportioning of induced draft fan 5 and the relevant work of gas blower 6, air and diesel oil or flammable waste liquid by frequency conversion tank 2 and housing 1, it is to increase fuel firing rate. When producing negative pressure in kiln, numerical value is sent in frequency conversion tank 2 and housing 1 by negative pressure transmitter 4, and then controls induced draft fan 5 and gas blower 6 operating frequency, it is achieved voltage stabilizing work in kiln, to reach the object of stably manufactured.
Below it is only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation. The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
