Detailed description of the invention
Be described in detail to characteristic sum principle of the present utility model below in conjunction with accompanying drawing, illustrated embodiment, only for explaining the utility model, not limits protection domain of the present utility model with this.
As shown in Figure 1, the waste gas uptake flue 3 that this utility model comprises rotary kiln 1 and is communicated with rotary kiln, waste gas uptake flue is the cylinder pipe vertically arranged.Be connected with the heat entrance of heat exchanger by elbow 4 in the latter half of waste gas uptake flue, be connected with the blower fan 2 of drying to waste gas uptake flue in the latter half of waste gas uptake flue and heat exchanger junction, the waste gas in waste gas uptake flue is blown in heat exchanger 5 by blower fan.In the middle part of described waste gas uptake flue, be provided with valve 6, when needs heat exchange, by valve closing, the waste gas that rotary kiln produces all is entered in heat exchanger by the effect of blower fan and carries out heat exchange utilization.The heat outlet of heat exchanger is communicated with connecting pipe the first half with waste gas uptake flue by expansion joint 7, waste gas after utilizing enters the first half of waste gas uptake flue by the heat outlet of heat exchanger and connecting pipe, be discharged in air by waste gas uptake flue again, thus realize heat exchange.
Heat exchanger comprises shell 53, heat exchange pipeline 54 and turnover reducer pipe 55 etc., and heat exchanger is existing heat exchanger structure.
Heat exchanger is vertically arranged and is fixed by support 9.The elbow be connected with waste gas uptake flue at heat exchanger and connecting pipe place are provided with discharger 8, and because there is certain dust and imperfect combustion particle in waste gas, in the process of waste gas by heat exchanger, dust falls in discharger 8.
Discharger 8 is connected with the input of FU chain-linked conveyer 10, and the output of FU chain-linked conveyer is connected with the raw material silo of rotary kiln.Fall to the dust in discharger 8 and imperfect combustion particle and be dumped into FU chain-linked conveyer by dust discharger 8, dust and imperfect combustion particle are sent back to elevator and enters raw material silo continuation production grog, the effect of dust discharger 8 is that dust is transported to FU chain-linked conveyer, pins wind and unloads discharging.
Be provided with the water inlet 51 be connected with the cold water storage cistern added water from trend heat exchanger in the side of heat exchanger, be provided with delivery port 52 at the opposite side of heat exchanger.Cold water enters heat exchanger from water inlet, and the water after heat exchange flows out to boiler from delivery port, and the hot water in boiler is delivered to each thermal water utilization mechanism by electric pump and delivery pipeline.
Further, the heat entrance of described heat exchanger and heat outlet are the mouth of pipe of reducing.The mouth of pipe effect of turnover reducer pipe is the turnover flow velocity and the direction that change flue gas, eliminates the stagnant area between housing import and export and tube sheet, effective heat exchange area is increased, namely when original heat exchange area is constant, heat exchange efficiency is improved.
This utility model is by being connected the waste gas uptake flue of rotary kiln with heat exchanger, achieve the utilization to heat in waste gas, decrease the waste of heat, simultaneously can also by discharger 8 and FU chain-linked conveyer to the recycling of dust granule in waste gas, reduce the pollution level of waste gas to environment, achieve energy-conserving and environment-protective.The hot water heated by heat exchanger can be used for on-site staff to use, and such as has a bath for warm, decreases fire coal or the energy needed for electrical heating separately.This system is reasonable, easy maintenance, and heat exchanger operation troubles is low, safe and reliable, and floor space is little, at ordinary times without special messenger's operation, has greatly saved coal heating, expense that electrical heating is had a bath, serves energy-saving and cost-reducing object.
Above-described embodiment is only the description carried out preferred embodiment of the present utility model; not scope of the present invention is limited; under the prerequisite not departing from the utility model design spirit; relevant technical staff in the field, to various distortion of the present utility model and improvement, all should expand in the determined protection domain of the utility model claims.
