Abstract
The invention discloses chemical equipment for producing neopentyl glycol, and particularly relates to a novel distilled water continuous running process which is used for reforming and applying a distilled water process pipeline. After methyl alcohol is synthesized, the dehydration and the dealcholization are carried out; and then, the rectification is carried out; and finally, finished neopentyl glycol is generated; when a dehydration working procedure is carried out, side product sodium formate is separated by a centrifuge; and waste water generated in the dehydration working procedure flows in a waste water communicating tank through a waste water tank, and then flows in a sewage treatment plant. By using the novel distilled water continuous running process, an original distilled water process pipeline is reformed, and synchronously, one waste water communicating tank is added newly, so that the continuous running of a producing device is achieved from batch production. The water discharging time is shortened greatly; a worker carries out operation without climbing a platform up and down; and the safety production is ensured. The four-kettle continuous running is increased from the original two-kettle running; the work efficiency is improved; the production cost is decreased; and the environmental pollution is reduced.
Description
Technical field: the present invention relates to a kind of chemical plant of producing NSC 6366, specifically is that a kind of zero(ppm) water that the transformation of zero(ppm) water process pipeline is used is moved novel process continuously.
Background technology: during dewatering process when at present producing NSC 6366; Will be when waste discharge with the vacuum pump draining of stopping, but because of water shoot is thinner, so row's primary water needs 70 minutes; Every row's primary water need be gone up lower platform twice; Increase labor strength and hidden danger, influenced production schedule, increased production cost.
Summary of the invention: the not smooth drawback of discharge of wastewater during dewatering process when the present invention has overcome the original production NSC 6366, increase waste water UNICOM jar is provided, make production equipment realize that by batch production a kind of zero(ppm) water that continuous operation is used moves novel process continuously.The objective of the invention is to realize through following technical scheme: described methyl alcohol is after synthesizing; Dewater again and dealcoholysis; Carry out rectifying then, produce the product NSC 6366 at last, when carrying out dehydration procedure, isolate the sub product sodium formiate through whizzer; The waste water that when dehydration procedure, produces flows into waste water UNICOM jar through waste water tank, flows into sewage work again.
The invention has the beneficial effects as follows: because original zero(ppm) water process pipeline is transformed, increase a waste water UNICOM jar simultaneously newly, make production equipment realize continuous operation by batch production.Make water discharge time have 70 minutes to shorten to 1 minute.Workman's operation need not gone up lower platform, only need guarantee safety in production in terrestrial operation.By original two stills operation, be increased to four stills and move continuously, make production throughput on original basis, improve 20%.Increase work efficiency, reduced production cost, reduced environmental pollution.
Description of drawings: Fig. 1 is a process flow sheet of the present invention
Embodiment: embodiment 1: as shown in Figure 1; Described methyl alcohol dewaters and dealcoholysis after synthesizing again, carries out rectifying then; Produce the product NSC 6366 at last; When carrying out dehydration procedure, isolate the sub product sodium formiate through whizzer, the waste water that when dehydration procedure, produces flows into waste water UNICOM jar through waste water tank, flows into sewage work again.
Embodiment 2: as shown in Figure 1, the waste water that produces during described dehydration procedure flows into sewage work through waste water tank.
Embodiment 3: as shown in Figure 1, described waste water tank is for side by side more than two or two.
