The high temperature of coal gas can be utilized with economizer, reduces energy waste, low temperature cyclone dust collectors carry out final dusting to coal gas, finally
Final dedusting and cooling are carried out into cooling system between dedusting.
Preferably, the front end cyclone dust collectors include reflux cyclone dust collectors and high-temperature cyclone dust extractor, and connect successively
Connect.The cyclone dust collectors that flow back are suitable for as the dedusting first step, recyclable a part of coal dust recycling, high-temperature cyclone dust extractor
Just complete the coal gas of high temperature of gasification.
Preferably, multiple filter bags are set in the metal film dust-remover, and filter bag is fixed on metal film dust-remover by card
Interior, the filter bag is made using the metal film of flexible, porous.Metal film is as filter bag, compared to traditional Fiber Materials bag-type dusting
Device, can bear higher temperature, longer life expectancy, while can eliminate electrostatic, and dust removal performance is improved with security performance.
Wherein, anti-blowpipe, anti-blowpipe connection gas bag are set at the filter pocket openings.Anti-blowpipe is used to blow off to be attached to filter bag
The particulate matter on surface.
Preferably, multigroup fin is set in the fin inter cooler, is connected between every group of fin by heat exchanger tube.Pass through heat exchange
Pipe and fin, cooling water can carry out heat exchange so as to cool down to coal gas with coal gas, and cooling water is but not directly contacted with coal gas, subtracts
The generation of sewage is lacked.
The heat exchanger tube both ends of every group of fin connect two different cisterns, two cistern connection coolings respectively
Tower.Two different cisterns place cold water and hot water respectively, and hot water is realized by entering cold water cistern after cooling down tower cooler
Reuse.
The utility model has the following advantages：
1. pair coal gas of high temperature realizes multistage dedusting, coal gas is progressively purified, dust removing effects are more preferable；
2. making full use of coal gas high-temperature, energy waste is reduced；
3. cooling water and coal gas mediate contact, more environmentally-friendly.

Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, cold process system between a kind of novel powdered coal temperature gasification and high dedusting, including gasification furnace 1, front end whirlwind remove
Cooling system between dirt device, waste heat boiler 4, economizer 5, low temperature cyclone dust collectors 6 and dedusting, above device are sequentially connected, front end rotation
Wind deduster includes reflux cyclone dust collectors 2 and high-temperature cyclone dust extractor 3, and is sequentially connected, and cooling system includes metal between dedusting
Film dust-remover 7 and fin inter cooler 8.
Gasification furnace 1 connects source of oxygen 11 and standby fan 12.
Setting is multiple in metal film dust-remover 7 passes through flower using filter bag 71 made of flexible, porous metallic film, filter bag 71
Plate 72 is fixed in metal film dust-remover 7.Metal film dust-remover 7 is divided into two separate spaces by card 72, and two independent empty
Between connect cold precipitator 6 and fin inter cooler 8 respectively, the opening of filter bag 71 is opened positioned at 8 side of connection fin inter cooler, filter bag 71
