The utility model has the advantages that: through the improvement on original production line, can effective recycling tail gas and in time handle, avoid the influence that toxic gas and dust caused to surrounding enviroment.
Description
Technical field
The utility model relates to the tail gas recycle process field on calcium hydroxide production line, is specifically related to the tail gas recycle for calcium hydroxide production line and bootstrap system.
Background technology
At present, existing calcium hydroxide production process is all carried out in calcining kiln body, raw material are respectively coal charge and building stones, toxic gas and a large amount of dust can be produced in calcination process, be respectively carbon monoxide and sulfur dioxide, if be wantonly disposed in air, can cause extreme influence to surrounding enviroment, existing production firm takes high-altitude directly to discharge or takes easy recovery and processing system to process toxic gas, can not reach basic goal.
Utility model content
The purpose of this utility model is exactly is take high-altitude directly to discharge or take easy recovery and processing system to process toxic gas for current above-mentioned existing production firm mostly, the deficiency of basic order can not be reached, and the calcium hydroxide production line with a kind of tail gas recycle process and dust pelletizing system is provided.
The utility model comprises calcium hydroxide production line, calcium hydroxide production line mainly comprises stone crusher pipeline, raw material dispensing line and calcining kiln body, it also has tail gas recycle and bootstrap system, tail gas recycle process and dust pelletizing system comprise at least two cleaning shafts, cyclone dust collectors, tail gas recycle process tank, solution reservoir, the pump housing and waste heat recovery pipeline, cleaning shaft is three-way pipe, be evenly distributed on the external side of calcining kiln, one end communicates with in calcining kiln body, one end is provided with removable cover, the other end is communicated to main pipeline one end jointly, the main pipeline other end communicates with the import of cyclone dust collectors, cyclone dust collectors top is provided with offgas outlet, and communicated with tail gas recycle process tank by tail gas recycle pipeline, tail gas recycle pipeline is provided with air-introduced machine, spray thrower is provided with in tail gas recycle process tank, the entrance point of the pump housing is communicated with by the port of export of pipeline with limy aqueous solution storage tank, the port of export of the pump housing is communicated with the spray thrower in tail gas recycle process tank by pipeline, tail gas recycle process tank is provided with waste heat recovery mouth, waste heat recovery mouth is communicated with in calcining kiln body by pipeline, waste heat recovery pipeline is provided with air-introduced machine.
The utility model has the advantages that: by the improvement on original production line, effectively can reclaim tail gas and process in time, avoiding the impact that toxic gas and dust cause surrounding enviroment.
Accompanying drawing explanation

Detailed description of the invention
As shown in Figure 1, the utility model comprises calcium hydroxide production line, calcium hydroxide production line mainly comprises stone crusher pipeline, raw material dispensing line and calcining kiln body 1, it is characterized in that it also has tail gas recycle and bootstrap system, tail gas recycle process and dust pelletizing system comprise at least two cleaning shafts 2, cyclone dust collectors 3, tail gas recycle process tank 4, solution reservoir 7, the pump housing 8 and waste heat recovery pipeline 9, cleaning shaft 2 is three-way pipe, be evenly distributed on outside calcining kiln body 1, one end communicates with in calcining kiln body 1, one end is provided with removable cover 2-1, the other end is communicated to main pipeline 6 one end jointly, main pipeline 6 other end communicates with the import of cyclone dust collectors 3, cyclone dust collectors 3 top is provided with offgas outlet, and communicated with tail gas recycle process tank 4 by tail gas recycle pipeline 5, tail gas recycle pipeline 5 is provided with air pump, spray thrower 4-1 is provided with in tail gas recycle process tank 4, the entrance point of the pump housing 8 is communicated with by the port of export of pipeline with limy aqueous solution storage tank 7, the port of export of the pump housing 8 is communicated with the spray thrower 4-1 in tail gas recycle process tank 4 by pipeline, tail gas recycle process tank 4 is provided with waste heat recovery mouth, waste heat recovery mouth is communicated with in calcining kiln body 1 by pipeline 9, waste heat recovery pipeline 9 is provided with air-introduced machine.
Embodiment: adopt at least 2 cleaning shafts 2, effectively can improve the rate of recovery of tail gas, the toxic gas produced when cyclone dust collectors 3 pairs of calcining kiln bodies 1 work and dust carry out centralized collection, dust is then concentrated and is dropped down onto in dust bag, toxic gas then enters in tail gas recycle process tank 4 by tail gas recycle pipeline 5 under the effect of air-introduced machine, by the pump housing 8, the liquid in limy aqueous solution storage tank 7 is directed in tail gas recycle process tank 4, and sprayed by spray thrower 4-1, reaction treatment is carried out to the sulfur dioxide gas in toxic gas, carbon monoxide can be applied to metal smelt field after centralized collection again, the effect of removable cover 2-1 is when operation irregularity appears in cleaning shaft 2, removable cover 2-1 can be opened observe in pipeline, it is closed condition during normal production.
Preferred embodiment 1: when after toxic gas tail gas recycle process tank 4, will be directed in calcining kiln body 1 by waste heat recovery pipeline 9 containing the gas had surplus heat by air-introduced machine again, is again carried out by these waste heats utilizing and producing, reaches the object of energy-saving and emission-reduction.
Preferred embodiment 2: the liquid in limy aqueous solution storage tank 7 is directed in tail gas recycle process tank 4 by the pump housing 8, and sprayed by spray thrower 4-1, reaction treatment is carried out to the sulfur dioxide gas in toxic gas, carbon monoxide then in toxic gas is then directed in calcining kiln body 1 by waste heat recovery pipeline 9 again, these waste heats are carried out again utilize and produce, reach the object of energy-saving and emission-reduction.
