Abstract
The utility model belongs to the technical field of chemical production, and particularly relates to a compound fertilizer tail-gas washing device. The compound fertilizer tail-gas washing device mainly aims to resolve the technical problems of absorption of waste gas and ammonia in tail gas and environment protection in a production process of compound fertilizer. The compound fertilizer tail-gas washing device comprises a pelletizer, a washer and a cyclone dust collector, wherein the side end face, the upper end face and the lower end face of the washer are communicated with the pelletizer, the cyclone dust collector and a pelletizing washing groove respectively, an induced draft fan is arranged between the washer and the cyclone dust collector, the lower side of the cyclone dust collector is communicated with a pipeline, and a gas outlet of the pipeline is connected with a tail gas washing tower. The compound fertilizer tail-gas washing device is simple in structure, can efficiently absorb and utilize the tail gas produced in a production process of the compound fertilizer, and is low in investment and high in return, the filtered tail gas is clean and can be directly exhausted to the atmosphere, and environment pollution is reduced.
Description
Technical field
The utility model belongs to the chemical production technical field, specifically a kind of composite fertilizer washing tail gas device.
Background technology
Now in chemical fertilizer production enterprise, the composite fertilizer's dust content reduced in composite fertilizer's exhaust emissions more and more is subject to people's attention, current domestic composite fertilizer manufacturing enterprise adopts cylinder to carry out granulation, imperfection due to production technology, the situation that exists dust and ammonia content to exceed standard in the exhaust emissions of granulation process, exist serious pollution to environment.
Summary of the invention
Goal of the invention of the present utility model:
Mainly to have a large amount of dust and ammonia, the technical problem that environmental pollution is serious in order to solve in the tail gas discharged in composite fertilizer's production process.
Summary of the invention of the present utility model:
A kind of composite fertilizer washing tail gas device is provided, comprise comminutor, washer and cyclone dust collectors, the washer side end face, upper surface and lower surface respectively with comminutor, cyclone dust collectors and granulation sink are connected, be provided with air-introduced machine between washer and cyclone dust collectors, the below of cyclone dust collectors is connected with pipeline, the pipeline gas outlet is connected with tail gas washing tower, the tail gas washing tower below pours into the aqueous solution of certain altitude by inlet channel, be provided with valve on inlet channel, centre position at tail gas washing tower is provided with screen pack, top at tail gas washing tower is provided with spray head, be provided with the pipeline be connected with the granulation sink in the bottom of tail gas washing tower, be provided with water pump on pipeline.
The beneficial effects of the utility model are:
Improve greatly composite fertilizer's absorption function of tail gas in process of production, reduced the pollution to atmosphere, protected environment.
the accompanying drawing explanation:
The structural representation that Fig. 1 is composite fertilizer's washing tail gas device.
In figure, 1 is comminutor; 2 is the granulation sink; 3 is washer; 4 is air-introduced machine; 5 is cyclone dust collectors; 6 is water pump; 7 is pipeline; 8 is the aqueous solution, and 9 is inlet channel; 10 is valve; 11 is tail gas washing tower; 12 is screen pack; 13 is spray head.
the specific embodiment:
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
As shown in Figure 1, comminutor 1 is connected with the side end face of washer 3, upper surface and lower surface at washer 3 are connected with respectively cyclone dust collectors 5 and granulation sink 2, air-introduced machine 4 is installed on the pipeline between washer and cyclone dust collectors, thus, composite fertilizer's tail gas of producing in washer through the first washing process, particle and tail gas are separated, the tail gas generated filters a part of waste gas and ammonia through the filtration of cyclone dust collectors, be connected with pipeline 7 below cyclone dust collectors, pipeline 7 supports are connected with tail gas washing tower 11, remaining waste gas and ammonia are in piping flow into tail gas washing tower 11, bottommost in tail gas washing tower 11 is provided with the aqueous solution 8, the aqueous solution 8 flow in tail gas washing tower 11 by inlet channel 9, be provided with valve 10 on inlet channel 9, with the flow of control water, in the centre position of tail gas washing tower 11, screen pack 12 is installed, on the top of tail gas washing tower 11, spray head 13 is installed, remaining waste gas and ammonia are through the absorption of the aqueous solution, the absorption of screen pack and filtration, dilution at the water smoke through the spray head ejection, substantially all will be dissolved in the aqueous solution, filtered fully and diluted, finally by clean exhaust emissions in atmosphere, reduced the pollution to atmosphere, protected environment, bottom at tail gas washing tower 11 can also be provided with the pipeline be connected with the granulation sink, be provided with water pump 6 on pipeline, make ammonia solution further mix with compound fertilizer granules, reach the function that refuse is utilizing, improved the output of composite fertilizer.
