Abstract
The utility model relates to an ACR (acrylic resin) emulsion polymerization anti-overflow recovery device, which belongs to the field of resin processing equipment in the chemical industry. The anti-overflow recovery device comprises a reactor kettle, and a feed inlet is arranged at the top of the reactor kettle. The acrylic resin emulsion polymerization anti-overflow recovery device is characterized in that a liquid storage tank is arranged on one side of the reactor kettle, one end of the liquid storage tank is communicated to the top of the reactor kettle via a pipeline, a control valve is mounted on the pipeline in a series connection manner, the other end of the liquid storage tank is communicated with the feed inlet of the reactor kettle through a pipeline, and a diaphragm pump is mounted on the pipeline in a series connection manner. Shortcomings of equipment in the prior art are overcome by the ACR emulsion polymerization anti-overflow recovery device. Since the material storage device which can be adjusted and controlled at any time and can return to delivery in time is added on the reactor kettle, the recovery device has the advantages of simple structure, easiness in implement, fine operation reliability and capabilities of overcoming overflow in operation of the reactor kettle thoroughly and guaranteeing production safety after being used.
Description
Technical field
The utility model belongs to chemical industry resin treatment apparatus field, is specifically related to the anti-still retrieving arrangement that emits of a kind of ACR letex polymerization.
Background technology
PVC processing aid ACR resin is to finish in the mode of letex polymerization.The process of letex polymerization is carried out in enamel reaction still, and the eliminating of reaction heat is an important problem in reaction process, and can it not only be related to the stability of operation control and keep the safety in production, and having a strong impact on the quality and the output of product.For body and high solids solution polymerization, reaction later stage viscosity sharply increases, the heat of reaction system has become the difficulty that is difficult to overcome, not only can cause the local superheating of material, make the debase of product, and the reaction of material is very violent, often causes the material in the reactor outwards to overflow in a large number; In addition, operator are in operating process, because incorrect operation or carelessness, also be easy to make material reaction very violent, cause and emit the still phenomenon, not only cause the loss of a large amount of materials, and bring very big potential safety hazard for normal production, how to address this problem for this reason, make reactor can stablize, move reliably, become the problem of person skilled research.
The utility model content
The purpose of this utility model is at above-mentioned deficiency of the prior art, prior art equipment is improved, provide a kind of simple in structure, easy to implement, working reliability is good, can thoroughly solve the reactor still phenomenon of emitting in service after the use, ensure the anti-still retrieving arrangement that emits of ACR letex polymerization of production safety.
For achieving the above object, the utility model is achieved through the following technical solutions:
It is the anti-still retrieving arrangement that emits of a kind of ACR letex polymerization, comprise reactor, the reactor top is provided with opening for feed, the present technique main points are that a side of reactor is provided with container for storing liquid, one end of container for storing liquid links by overflow passage and reactor top, go here and there cartridge control valve on this overflow passage, the container for storing liquid the other end links by the opening for feed of return line and reactor, string dress surge pump on this return line.
Safety performance when working for further guarantee reactor, the overflow passage at described container for storing liquid top is a three-port structure, the top of this overflow passage is provided with bursting diaphragm.
Described control valve can adopt butterfly valve.
After the deficiency that the utility model exists at prior art equipment is carried out above-mentioned improvement, owing to installed additional and can regulate and control at any time to reactor, and can in time cover the material storage device of conveying, therefore have simple in structure, easy to implement, working reliability is good, can thoroughly solve the reactor still phenomenon of emitting in service after the use, ensures the advantage of production safety.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: mounting structure synoptic diagram of the present utility model.
Among the figure: 1 surge pump; 2 return lines; 3 container for storing liquids; 4 overflow passages; 5 reactors; 6 control valves; 7 three-port structures; 8 bursting diaphragms; 9 opening for feeds.
Embodiment
As shown in Figure 1, the anti-still retrieving arrangement that emits of this ACR letex polymerization, comprise reactor 5, reactor 5 tops are provided with opening for feed 9, the present technique main points are that a side of reactor 5 is provided with container for storing liquid 3, and an end of container for storing liquid 3 links by overflow passage 4 and reactor 5 tops, string cartridge control valve 6 on this overflow passage 4, container for storing liquid 3 the other ends link by the opening for feed 9 of return line 2 with reactor 5, string dress surge pump 1 on this return line 2.
Safety performance when working for further guarantee reactor 5, the pipeline at described container for storing liquid 3 tops is a three-port structure 7, the top of this pipeline is provided with bursting diaphragm 8.
Described control valve 6 can adopt butterfly valve.
When reactor 5 enters working order, when material begins to react, when too fast or misoperation causes the material vigorous reaction owing to material reaction speed, if ON cycle water for cooling and in reactor 5, add water one time, a large amount of heats can't in time be shifted away, and when material is outwards overflowed, open control valve 6, make material enter into container for storing liquid 3 by overflow passage 4.When treating that material reaction speed is slow, the liquid level of reactor 5 the insides also can reduce, and at this moment with the recirculated water service temperature that is cooled to regulation slowly, then control valve 6 is closed.Cause the material that spills in the container for storing liquid 3 because of the material vigorous reaction under surge pump 1 effect, be transported to the charging opening of reactor 5, join in the reactor 5, this part material is reacted normally again through charging opening by return line 2.Operation gets final product and so forth.
After the deficiency that the utility model exists for prior art equipment is carried out above-mentioned improvement, owing to installed additional and can at any time regulate and control for reactor 5, and can in time cover the material storage device of conveying, therefore have simple in structure, easy to implement, functional reliability is good, can thoroughly solve the reactor still phenomenon of emitting in service after the use, ensures the advantage of production safety.
