Abstract
A paraformaldehyde production device comprises a reactor, a feeding pipeline, a circulating pipeline, a discharging pipeline and a cleaning pipeline, wherein the discharging pipeline is provided with a discharging valve, the tail end of the cleaning pipeline is connected with the discharging pipeline at the lower end of the discharging valve, and the feeding pipeline is connected with the discharging pipeline at the upper end of the discharging valve by the aid of the circulating pipeline. The discharging valve is used for controlling the cleaning pipeline to clean the feeding pipeline and the discharging pipeline, so that blockage in the pipelines can be prevented effectively.
Description
Technical field
The utility model relates to a kind of Paraformaldehyde 96 production equipment, especially relates to a kind of Paraformaldehyde 96 production equipment that cleans pipeline that has, and this device can effectively prevent the generation that pipeline stops up.
Background technology
In the production process of Paraformaldehyde 96 (the especially Paraformaldehyde 96 of low polymerization degree), formaldehyde solution simmer down to 75～85wt% need be supplied in the reactor then polymerization reaction take place under stopper, catalyzer condition.But so the formaldehyde solution of high density is very easy to autohemagglutination takes place, and generates full-bodied Paraformaldehyde 96, causes the pipeline in the production equipment to stop up, and influences the normal operation of production equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of Paraformaldehyde 96 production equipment that has self-cleaning system at the shortcoming of prior art existence, can effectively prevent the generation that pipeline stops up.
The technical solution of the utility model is: a kind of Paraformaldehyde 96 production equipment, comprise reactor, feed line, circulation line, discharge line, and cleaning pipeline, wherein discharge line is provided with blow-off valve, the end that cleans pipeline links to each other with the discharge line of blow-off valve lower end, and feed line links to each other by the discharge line of circulation line with the blow-off valve upper end.
Further, be provided with high-pressure pump, under meter and vacuum breaker successively on the above-mentioned cleaning pipeline.Wherein, high-pressure pump provides high-pressure cleaning liquid to detergent line, utilizes the tamper in the high pressure washing pipeline; Scavenging solution flow in the under meter monitoring pipeline judges whether pipeline stops up; Vacuum breaker can prevent that the liquid return of inside reactor is to cleaning pipeline.Described scavenging solution mainly is the aqueous solution of formaldehyde.
The beneficial effects of the utility model are: effectively prevent to stop up in the pipeline, and easy and simple to handle, improved production efficiency.

Embodiment
Below in conjunction with Fig. 1 the utility model is described further:
As shown in Figure 1, a kind of Paraformaldehyde 96 production equipment, comprise reactor 1, feed line 2, circulation line 3, discharge line 5, and cleaning pipeline 6, wherein discharge line 5 is provided with blow-off valve 4, the end that cleans pipeline 6 links to each other with the discharge line of blow-off valve 4 lower ends, and feed line 2 links to each other by the discharge line of circulation line with blow-off valve 4 upper ends.Be provided with high-pressure pump 7, under meter 8 and vacuum breaker 9 on the above-mentioned cleaning pipeline 6 successively.
Concrete cleaning operation process is as follows: the formaldehyde among the low concentration formaldehyde NaOH solution tank NaOH A is concentrated into 75～85wt%, pumps into highly concentrated formaldehyde solution jar B, be pumped to then in the reactor 1, add the Paraformaldehyde 96 of stopper, Catalyst Production low polymerization degree; During cleaning, reactor 1 stops discharging, close the discharge port (not shown), open blow-off valve 4, high-pressure pump 7 pumping high-pressure cleaning liquids enter feed line 2 through under meter 8, vacuum breaker 9, blow-off valve 4, circulation line 3, and feed line 2 is cleaned, stable up to the scavenging solution flow that under meter 8 shows, feed line 2 conducting is described; Close blow-off valve 4 then, high-pressure pump 7 pumping high-pressure cleaning liquids enter discharge line 5 through under meter 8, vacuum breaker 9, and discharge line 5 is cleaned, and are stable up to the scavenging solution flow that under meter 8 shows, discharge line 5 conductings are described.
The utility model can pass through or adopt existing techniques in realizing without the technical characterictic of describing; do not repeat them here; certainly; above-mentioned embodiment is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
