Abstract
The invention discloses a super fuel coal fuel gas environmental protection steam boiler. Due to the adoption of principles of classification lamination and fuel coal gas production furnace, a boiler can be heated quickly by inletting the air and supplying the oxygen from the bottom part and can be subjected to secondary air inlet and oxygen supply, petroleum coke and carbon monoxide can be fully burnt, water is supplied for the inner layer of the boiler through the circulating of waste heat at the outer layer when the waste heat is dispersed through the upper part and the periphery of the boiler as the upper part adopts the water inletting, and the utilization rate of fuel coal fuel gas is further increased; and the environment pollution is simultaneously reduced as a dust removing device is adopted.
Description
Technical field:
The present invention relates to a kind of brand-new super coal burning and gas burning environment protection steam boilers, especially can improve coal utilizaton rate, reduce the environmental pollution energy savings.
Background technology:
At present, known coal-fired steam boiler on the market, be coal to be put into lean on the chimney draught of boiler self combustion-supporting in the boiler, the consequence one that produces like this is that carbon monoxide and coal tar can not completing combustion produce environmental pollution, the 2nd, and coal utilizaton rate is low, the 3rd, heat up slow, the 4th, no matter you are boiled with whole water with How much water, wasted so a large amount of resources and time, moreover boiler is a heat dump, it is again a huge radiator simultaneously, and therefore utilization rate coal-fired and combustion gas is low.
Summary of the invention:
For the deficiency that overcomes existing coal burning and gas burning boiler (produces environmental pollution, coal combustion Han utilization rate is low, heat up slow, the waste of carbon monoxide and tar), the invention provides a kind of brand-new high efficient super energy coal burning and gas burning environment protection steam boilers, effectively carbon monoxide and coal tar are fully burnt, improve greatly the utilization rate of coal burning and gas burning and be rapidly heated.
Technical scheme:
Boiler is divided into top, the middle part, bottom and inside and outside two-layer and dust arrester: a producer is set in the boiler bottom, producer is positioned at the boiler bottom center, on every side by water ring around, the below is that the activity grate is put, and what place between the above and the boiler internal quick heater is burner noz(zle) device for the second-time burning air feed; Inside is the boiler internal quick heater, the boiler internal quick heater is comprised of top water heater and following coil pipe and coil pipe protective layer, coil pipe is to be welded by three steel bars to be fixed on up and down in the coil pipe protective layer, above the water heater, it can be water heating in the water heater by standpipe that the standpipe hot-air is arranged, and the Pressure gauge of top and water sealing (sealing water) pipe pass from upper boiler and extend upward, the steam pipe on the quick heater, water thermometer, boiled water pipe are to stretch out by the boiler centre exit; Boiler middle part is made of inner small and outside big two-layer sealing, and the inside is water, is positioned at the periphery of boiler internal quick heater, and the above has water level to take into account steam pipe on handle hole and the boiler quick heater, the extended centre exit of water thermometer boiled water pipe; The boiler internal quick heater is to connect the private water supply pipe by many root beads to be connected with the producer of bottom, and the water source is provided from bottom to top.Upper boiler is that inside and outside taper shape two-layer and that horizontal water tube is up-small and down-big consists of, be positioned on the boiler middle part under the dedusting water pipe, adopt ring flange between them, screw connects maintenance, the boiler middle part is to be positioned on the producer of boiler bottom, be fixedly connected with screw by ring flange, their joint portion is separated by with resistant to elevated temperatures heat-preservation cotton its temperature can not directly be transmitted, advance coal from handle hole and the coal groove at middle part, use again the oxygen supply of blower fan air intake from the bottom, producing high temperature in the boiler internal combustion is that boiler is heated, when carbon monoxide and coal tar enter burner noz(zle) device producer coal gas above the boiler and goes out to manage, carbon monoxide and tar are fully burnt for again its secondary oxygen supply, provide heat for the boiler internal quick heater produces high temperature, dust is extracted in the collection ash bucket by air exhauster and sinks under water, and residual air is then passed basket strainer and discharged.
The beneficial effect of the technology of the present invention;
Because boiler has adopted hierarchical classification and coal for producing steam stove principle, from the bottom air inlet oxygen supply boiler is rapidly heated, with the secondary air oxygen supply, tar and carbon monoxide are fully burnt, when waste heat by top with when spreading all around because what adopt is to intake from the top down, be the water supply of boiler internal layer through outer circulation, therefore further improve the utilization rate of coal burning and gas burning, reduced simultaneously the pollution to environment
