Abstract
The invention relates to the field of urban household rubbish incinerating, and discloses a method for controlling the pressure of air cooling walls of a household rubbish incinerator. A pipe from an incinerator room to a primary air fan sequentially passes through a cooling air blower flow control valve, a cooling air blower, a left-air-cooling-wall flow control valve, a right-air-cooling-wall flow control valve, a cooling induced draft fan flow control valve and a cooling induced draft fan. Pressure losses of an air blowing pipe and the air cooling walls are avoided through a pressure head of the cooling air blower. Pressure losses of an air guiding pipe and a pipe of the primary air fan are avoided through a pressure head of the cooling induced draft fan. According to the method, the temperature of the walls of the incinerator can be effectively lowered and easily adjusted, high-temperature hot air of a hearth of the incinerator can be kept leaked into the air cooling walls through micro-positive pressure heat exchanging of the air cooling walls, partial combustion caused by the fact that partial leaked cooling air of the hearth of the incinerator is excessively large in amount is avoided, and the method for controlling the pressure has the good adaptability to changes of fuel of the incinerator.
Description
Technical field
The present invention relates to burning city domestic garbage field, particularly the compress control method of effective cooling incinerator air cooling wall in burning city domestic garbage processing.
Background technology
Air cooling refractory brickwork (be called for short air cooling wall) is boiler room normal temperature air to be delivered to the back side of refractory brick, and refractory brick surface temperature is reduced to approximately 750 ℃ by approximately 1000 ℃, thus prevent slagging scorification generation, adhere to and grow up, the life-span of raising refractory brick.For the air cooling control of pressure within the walls, directly affect cooling-air heat transfer effect, if even pressure is controlled the normal operation that improper meeting causes burning process.Air cooling is when cooling-air pressure is negative pressure within the walls, the incinerator burner hearth high-temperature hot air air cooling wall that bleeds, and air cooling wall can not get effective cooling and causes the adverse effects such as slagging scorification of air cooling wall, shortens refractory brick life; Air cooling is when cooling-air malleation is more than needed within the walls, and the cooling-air incinerator burner hearth that too much bleeds, forms local oxygen-rich area partial combustion, destroys burning air atmosphere in stove, follow-up concentration of flue gas pollutants generated to control etc. all impact.
Summary of the invention
For overcoming in above-mentioned prior art because of the air cooling adverse effect that cooling-air pressure causes within the walls, the present invention proposes one way of life incinerator air cooling wall compress control method, from boiler room to primary air fan pipeline, successively by cooling pressure fan flow control valve, cooling pressure fan, left and right air cooling wall flow control valve, another cooling air-introduced machine flow control valve and another cooling air-introduced machine; Cooling pressure fan pressure head overcomes air-supply pipeline and air cooling wall crushing, and maintains air cooling wall outlet cooling-air pressure-fired; Cooling air-introduced machine pressure head overcomes induced pipe and to primary air fan pipeline crushing.
Above-mentioned cooling pressure fan suction boiler room air, a minute two-way enters respectively left and right air cooling wall forced heat-exchanging, by forced heat-exchanging, effectively reduces incinerator air cooling wall temperature, and the hot-air after heat exchange enters primary air fan through cooling air-introduced machine and melts down burning.
Further, cooling pressure fan flow control valve and cooling air-introduced machine flow control valve are installed respectively before cooling pressure fan and cooling air-introduced machine; Air cooling wall (left side)/(right side) entrance is installed respectively air cooling wall (left side)/(right side) flow control valve.By coolingly giving, air-introduced machine Flux Valve Control and regulate the air mass flow of blower fan separately; Air cooling wall (left side)/(right side) flow control valve is used for distributing cooling air volume separately.
Further, cooling pressure fan pressure head overcomes air-supply pipeline and air cooling wall crushing.Conventionally, cooling-air inlet scoop, boiler room is to cooling air blower inlet pipeline crushing approximately 200 Pa, cooling pressure fan is to air cooling wall entrance pipe crushing approximately 1200 Pa, air cooling wall crushing approximately 1800 Pa, air cooling wall outlet cooling-air pressure approximately 100 Pa, these a few part crushings and pressure provide by cooling pressure fan, and cooling pressure fan pressure head is about 3300 Pa.
Further, cooling pressure fan pressure head maintains air cooling wall outlet cooling-air pressure-fired, pressure-fired be relative pressure higher than atmospheric pressure 0 ~ 200 Pa, during actual motion, take and keep pressure-fired 100 Pa as good.The heat exchange of air cooling wall pressure-fired can maintain the incinerator burner hearth high-temperature hot air air cooling wall that bleeds, and avoids again burning the burner hearth Local cooling wind partial combustion excessive and that cause that bleeds.
Further, cooling air-introduced machine pressure head overcomes induced pipe and to primary air fan pipeline crushing.Conventionally, air cooling wall is exported to the cooling air-introduced machine entrance of furnace wall crushing approximately 1100 Pa, and the cooling air-introduced machine of furnace wall is exported to primary air fan pipeline crushing approximately 100 Pa, and this two parts crushing provides by cooling air-introduced machine, and cooling air-introduced machine pressure head is about 1200 Pa.
One way of life incinerator air cooling wall compress control method of the present invention, can effectively solve the air cooling pressure control problem of cooling-air within the walls, when not affecting the normal operation of burning process, does not make air cooling wall obtain effective cooling.The present invention can effectively reduce incinerator wall temperature and be easy to adjusting; The heat exchange of air cooling wall pressure-fired can maintain the incinerator burner hearth high-temperature hot air air cooling wall that bleeds, and avoids again burning the burner hearth Local cooling wind partial combustion excessive and that cause that bleeds; This compress control method has good adaptability to the variation of incinerator fuel.
