Abstract
The invention relates to a biomass gasification station capable of heating a purification chamber. A gasifier and a dry dust collector are located in a pit of a gasification chamber, a spray dust collector in the gasification chamber is connected with the dry dust collector in the pit through a gas delivery pipeline, so that high-temperature equipment is far away from workers, and scald accidents are prevented. In order to meet the heating requirement of the purification chamber, a sealing casing pipe is additionally mounted on the gas delivery pipeline between the spray dust collector and the dry dust collector, two ends of the sealing casing pipe are sequentially connected with an air inlet pipeline and an air outlet pipeline, the air inlet pipeline guides cold air into the sealing casing pipe for heat exchange through an outdoor axial flow fan, hot air formed after heat exchange is guided into the purification chamber through the air outlet pipeline, and heating of the purification chamber is realized. Under the action of heat exchange, the gas delivery pipeline is not in the red-hot state, the aging speed of the gas delivery pipeline is retarded, and the probability of damage to the gas delivery pipeline is reduced, so that the probability of safety accidents is decreased.
Description
Technical field
The invention belongs to biomass gasification technology field, particularly relate to a kind of gasifying biomass station can heated to Clean room.
Background technology
Present stage, gasifying biomass station is built in rural area mostly, be not both with city the gasifying biomass station being built in rural area and lack central heating facility, therefore, the heat that heating in gasification station directly utilizes gasification reaction to produce often, now can cause following problem, because gasifying biomass station forms with Clean room between gasifying, for completing gasification reaction between wherein gasifying, Clean room has been used for gas-purification, and gasification reaction can make the temperatures as high more than 1000 DEG C in vapourizing furnace, the high-temperature fuel gas that gasification reaction generates can export through gas pipe line, and then carry out gas-purification, and gas-purification is divided into dry purification and wet purification, without any cooling measure before high-temperature fuel gas enters wet purification equipment from dry purification equipment, this just causes vapourizing furnace after blow-on, fuel gas transportation pipeline between dry purification equipment and wet purification equipment can be in high temperature always scorch state, along with the increase of time, fuel gas transportation pipeline even there will be red heat phenomenon, potential safety hazard is brought to gasifying biomass station, concrete potential safety hazard is as follows:
1. the fuel gas transportation pipeline being in red heat state can be considered naked light, once there is gas leaking, very likely presence of fire or even explosion hazard in gasification station;
2. the fuel gas transportation pipeline being in red heat state also likely scalds the staff in gasification station;
3. because fuel gas transportation pipeline is in red heat state for a long time, accelerate the aging speed of fuel gas transportation pipeline, and then increase the damaged probability of fuel gas transportation pipeline appearance, once fuel gas transportation pipeline occurs that breakage will there will be gas leaking, thus cause great potential safety hazard.
In order to the pipeline of high temperature and the wet purifying decice that gas leaking easily occurs are left, technician is between gasification and be provided with hermetic fireproof brickwork between Clean room and isolate, although reduce the occurrence probability of security incident, but also reduce gasifying biomass station environmental compatibility, central heating facility is lacked owing to being built in gasifying biomass station, rural area, isolated Clean room can not get the heat that gasification reaction produces, cause Clean room temperature in the winter time can be very low, again because wet purification equipment is difficult to normal operation at low temperatures, particularly temperature is lower than sub-zero zero, wet purification equipment is often caused to occur bursting by freezing phenomenon, therefore, when winter temperature is lower than sub-zero zero, most gasification station can only be stopped work and be waited to produce, although there is indivedual gasification station can be equipped with electric heating facility for Clean room, but electric heating facility needs to consume extra electric energy, not only add running cost, and run counter to the theory of the energy-saving and emission-reduction that biomass gasification technology is advocated.
