Abstract
The utility model relates to a prevent climbing film evaporator of jam. The purpose is that the climbing film evaporator that provides should have the characteristics that the heating pipe difficultly blockked up, production efficiency is high. Technical scheme is: a prevent climbing film evaporator of jam, is including the raw material chamber, heater and the separation chamber that set gradually from lower to upper, the last feed inlet that is equipped with of raw material chamber, be equipped with steam inlet and condensate outlet on the heater, the vertical heating pipe of arranging a plurality of intercommunication raw material chamber and separation chamber in the casing of heater, be equipped with liquid outlet and steam outlet in the separation chamber, the bottom of separation chamber is the last tube sheet with heating pipe upper end switch -on, raw material chamber's top is the lower tube sheet with the switch -on of heating pipe lower extreme, its characterized in that: the heating pipe upwards stretches out the certain height of tube sheet.
Description
Technical field
The utility model relates to a kind of production equipment of polyisobutene, specifically a kind of climbing film evaporator.
Background technology
Need to use climbing film evaporator in the process of producing polyisobutene, its specific works principle is as follows: the feed chamber of heater base introduced by the polyisobutene material after preheating, then continue to rise after heating through heating tube and enter separation chamber's (simultaneously driving subsequent material to enter in heating tube), last in separation chamber through gas-liquid separation, concentrate is discharged by liquid outlet, and steam is discharged by steam (vapor) outlet.
The weak point that existing climbing film evaporator exists is: the concentrate after gas-liquid separation is deposited on the upper perforated plate bottom separation chamber, is easily flowed back in heating tube by the through hole of upper perforated plate and causes heating tube to block, have impact on production efficiency.
Utility model content
The purpose of this utility model overcomes the deficiency in above-mentioned background technology, provides a kind of climbing film evaporator, and this climbing film evaporator should have the feature that heating tube not easily blocks, production efficiency is high.
The technical solution of the utility model is: a kind of anticlogging climbing film evaporator, comprise set gradually from lower to upper feed chamber, heater and separation chamber; Described feed chamber is provided with charging aperture; Described heater is provided with steam inlet and condensation-water drain, is vertically furnished with the heating tube of some connection feed chamber and separation chamber in the housing of heater; Described separation chamber is provided with liquid outlet and steam (vapor) outlet; The bottom of described separation chamber is the upper perforated plate connected with heating tube upper end, and the top of described feed chamber is the lower perforated plate connected with heating tube lower end; It is characterized in that: described heating tube protrudes upward upper perforated plate certain altitude.
Described heating tube protrudes upward upper perforated plate 5-10cm.
The beneficial effects of the utility model are:
In the utility model, the top of heating tube protrudes upward upper perforated plate, can effectively avoid concentrate to flow backwards, heating tube not easily be blocked, thus improves production efficiency.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is the main TV structure schematic diagram of prior art.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, a kind of anticlogging climbing film evaporator, comprises feed chamber 1, heater 2 and separation chamber 3 from lower to upper successively.
Described feed chamber is provided with the charging aperture 11 for inputting polyisobutene material.
Described heater is for heating polyisobutene material; Described heater is provided with steam inlet 21 and condensation-water drain 22, and is vertically furnished with some heating tubes 23 in the housing of heater, and feed chamber connects separation chamber by heating tube; The bottom of described separation chamber is upper perforated plate 51, and heating tube upper end is docked with the through hole of upper perforated plate, and the top of feed chamber is lower perforated plate 52, and heating tube lower end is docked with the through hole of lower perforated plate; External steam inputs heater inner chamber by steam inlet, heats the material through heating tube, and the condensed water produced after external steam cooling is discharged by condensation-water drain.
Described separation chamber is provided with concentrated solution outlet 31 and steam (vapor) outlet 32, and material enters through gas-liquid separation behind separation chamber, and the concentrate of generation is discharged by liquid outlet, and the steam of generation is discharged by steam (vapor) outlet.
Improvements of the present utility model are:
The top 23.1 of described heating tube protrudes upward upper perforated plate certain altitude (being generally 5-10cm), so just can prevent concentrate from flowing backwards, and avoids blocking heating tube (impact reduces evaporation effect), improves production efficiency.
Claims (2)
