Positive propyl ether apparatus for producing of chloroethyl, including the retort, still include blending tank, crude jar, rectification jar and product jar, wherein, set up the blending tank before the retort, set gradually crude jar, rectification jar, product jar after the retort, blending tank, retort, crude jar, rectification jar and product jar are consecutive, the blending tank still links to each other with thionyl chloride head tank, catalyst storage tank, the positive propoxyl group ethanol head tank of 2 - respectively, and rectification tank deck portion links to each other with the thionyl chloride head tank, and rectification tank bottoms portion links to each other with the positive propoxyl group ethanol head tank of 2 -. The utility model discloses simple structure, no waste water produce, heat up in a steamer before the rectification production and can carry out cyclic utilization with the cauldron bed charge, and product quality is stable, and purity is high, and the yield is high, and the water content is low.
Description
Technical field
The utility model belongs to chemical production device field, is specifically related to a kind of chloroethyl positive propyl ether production equipment.
Background technology
Chloroethyl positive propyl ether is one of important source material preparing herbicide pretilachlor, and this weedicide is a kind of efficient, low toxicity major choice bud phase weedicide, is widely used in Rice Cropping field.Along with the fast development of pesticide industry, on the one hand, the demand of chloroethyl positive propyl ether constantly increases; Another aspect it is also proposed higher requirement to the quality of chloroethyl positive propyl ether and technique environmental protection.
There is the problems such as unstable product quality, yield is low, wastewater flow rate is large, structure is loaded down with trivial details in tradition chloroethyl positive propyl ether production equipment, can not meet the requirement of market to product.Therefore develop a kind of efficient, safety, the chloroethyl positive propyl ether production equipment of environmental protection has great importance.
Utility model content
According to above deficiency of the prior art, technical problem to be solved in the utility model is: provide a kind of constant product quality, yield high, produces, structure simple chloroethyl positive propyl ether production equipment without waste water.
The utility model solves the technical scheme that its technical problem adopts:
Described chloroethyl positive propyl ether production equipment, comprise retort, also comprise mixing tank, crude product tank, rectifying tank and products pot, wherein, before retort, mixing tank is set, set gradually crude product tank, rectifying tank, products pot after retort, mixing tank, retort, crude product tank, rectifying tank are connected successively with products pot; Mixing tank is also connected with sulfur oxychloride head tank, catalyzer storage tank, 2-positive propoxy ethanol raw material tank respectively, and rectifying tank top is connected with sulfur oxychloride head tank, and rectifying pot bottom is connected with 2-positive propoxy ethanol raw material tank.
Described mixing tank side arranges sulfur oxychloride head tank and catalyzer storage tank respectively, and mixing tank opposite side arranges 2-positive propoxy ethanol raw material tank.
Principle of work and process:
During work, raw material, after mixing tank mixes, arrives retort, react in retort, the crude product obtained enters crude product tank, after the crude product of crude product tank enters rectifying tank, rectifying heats up in a steamer cover for recycle in sulfur oxychloride before producing, front heating up in a steamer enters sulfur oxychloride head tank from rectifying tank top.The still bed material cover that rectifying produces is used for recycle in 2-positive propoxy ethanol, and still bed material enters 2-positive propoxy ethanol raw material tank from rectifying pot bottom.
The beneficial effect that the utility model has is:
The utility model structure is simple, without waste water generation, rectifying is heated up in a steamer before producing can carry out recycle, constant product quality with still bed material, and purity is high, and yield is high, and water content is low.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1, sulfur oxychloride head tank; 2, catalyzer storage tank; 3, retort; 4, crude product tank; 5, rectifying tank; 6, products pot; 7, mixing tank; 8,2-positive propoxy ethanol raw material tank.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, described chloroethyl positive propyl ether production equipment, comprise retort 3, also comprise mixing tank 7, crude product tank 4, rectifying tank 5 and products pot 6, wherein, arrange mixing tank 7 before retort 3, set gradually crude product tank 4, rectifying tank 5, products pot 6 after retort 3, mixing tank 7, retort 3, crude product tank 4, rectifying tank 5 are connected successively with products pot 6; Mixing tank 7 is also connected with sulfur oxychloride head tank 1, catalyzer storage tank 2,2-positive propoxy ethanol raw material tank 8 respectively, and rectifying tank 5 top is connected with sulfur oxychloride head tank 1, is connected bottom rectifying tank 5 with 2-positive propoxy ethanol raw material tank 8.
Described mixing tank 7 side arranges sulfur oxychloride head tank 1 and catalyzer storage tank 2 respectively, and mixing tank 7 opposite side arranges 2-positive propoxy ethanol raw material tank 8.
During work, raw material is after mixing tank 7 mixes, arrive retort 3, react in retort 3, the crude product obtained enters crude product tank 4, after the crude product of crude product tank 4 enters rectifying tank 5, rectifying heats up in a steamer cover for recycle in sulfur oxychloride before producing, front heating up in a steamer enters sulfur oxychloride head tank 1 from rectifying tank 5 top.The still bed material cover that rectifying produces is used for recycle in 2-positive propoxy ethanol, and still bed material enters 2-positive propoxy ethanol raw material tank 8 bottom rectifying tank 5.In the product introduction products pot 6 that rectifying obtains.The utility model rectifying is heated up in a steamer before producing can carry out recycle, constant product quality with still bed material, and purity is high, and yield is high, and water content is low.
