According to the filter drum, the shortcomings of low stability and low reliability of long-time periodic continuous running of the filter drum of the common paraffin filter in the prior art are solved; and due to the design, the filter drum has the advantages of compact structure, convenience for washing, good filter effect, high reliability and long-time periodic continuous and stable running.

Description

The filter cylinder of paraffin press

Technical field

The utility model relates to a kind of filter cylinder of paraffin press.

Background technology

Domestic hydrorefining paraffin wax device is mainly processed through the furfural solvent refining, subtracting two, subtract three-way scale wax after the benzol-kentone dewaxing.State's finished product paraffin at home and abroad is in great demand in market very much at present, is the important component part of each business economic benefit.Contain various impurity in the paraffin, can make heat exchanger or miscellaneous equipment fouling or obstruction on the one hand behind the access to plant, the heat exchange effect of heat exchanger falls and reduces in the pressure that increases equipment.The existence of mechanical admixture has influenced the running life of each pump mechanical seal significantly.The more important thing is that polymer such as solid particle and colloid gets into the refining reaction device in the paraffin, possibly pollute catalyst or make fouling of catalyst, green coke, reduction activity; Cause the reactor bed pressure drop to increase, thereby cause the generation of catalyst failure accident, labor is opened, idle time cost and catalyst costs; Influence the economic benefit of device, must take off contaminant filter to hydrogenating materials paraffin for this reason, heat radiation causes temperature to descend but existing paraffin press is because paraffin is in operation; Viscosity rises very fast, and the filter cake bonding is the jail, causes the flushing difficulty; Its long period is the poor stability of operation continuously, and reliability is low.

Summary of the invention

For the continuous poor stability that moves of the filter cylinder long period that overcomes common paraffin press in the prior art; The problem that reliability is low; The utility model provides a kind of filter cylinder of paraffin press, but the compact conformation of the filter cylinder of this paraffin press, convenient, the good reliability long period continous-stable operation of flushing.

The utility model solves the technical scheme that its technical problem adopted: comprise the filter core in housing and the housing; The top of housing is provided with the medium delivery outlet; Lower part of frame is provided with the medium input port, outside housing, coats companion's thermal jacket, and companion's thermal jacket is provided with companion's hot joining inlet and the outlet of companion's hot joining.

Housing is connected and composed by upper half shell and lower half shell, and upper half shell is provided with the medium delivery outlet, and lower half shell is provided with the medium input port, and companion's thermal jacket is coated on outside the lower half shell.

The utility model is through above-mentioned concrete design, but has the advantage that compact conformation, flushing convenience, good filtration effect, good reliability long period continous-stable move.

Description of drawings

The detailed content of the utility model is described below in conjunction with accompanying drawing and embodiment.

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the structural representation that the utility model is installed and used.

The specific embodiment

As shown in the figure; The utility model comprises the filter core 2 in housing 1 and the housing 1, and the top of housing 1 is provided with medium delivery outlet 3, and the bottom of housing 1 is provided with medium input port 4; Outside housing 1, coat companion's thermal jacket 5, companion's thermal jacket 5 is provided with companion's hot joining inlet 6 and companion's hot joining outlet 7.The further design of the utility model is that housing 1 is connected and composed by upper half shell 1A and lower half shell 1B, and upper half shell 1A is provided with medium delivery outlet 3, and lower half shell 1B is provided with medium input port 4, and companion's thermal jacket 5 is coated on outside the lower half shell 1B.Many filter cores 2 are housed in the filter cylinder; The wedge shape that filter core 2 adopts the 316L stainless steel to be made into is twined silk filter core (25 μ m～50 μ m); The combined filtering operation pressure reduction regulation and control (design of 1KPa～500KPa); Reach 99% greater than (25 μ m～50 μ m) particulate removal rate in the control paraffin, realize controlling exactly paraffin impurity particle degree and operating index requirement continuously.Micro gap between the wedge type silk forms section and helps backwash.During the filter bringing normally into operation; The control valve 9 of often opening of connecting between filter cylinder and the medium input pipe 8 is opened, and the normally closed control valve 11 of connecting between filter cylinder and the blow-off pipe 10 is closed, and the paraffin medium has in the filter cylinder of accompanying thermal jacket 5 through 8 entering of medium input pipe; The paraffin medium is from passing through the many filter cores 2 the filter cylinder down; Outer surface by filter core 2 intercepts the particle foreign material in the raw material, and clean liquid is sent into reactor or container by interior discharge through medium efferent duct 12.Along with the aggregation of holding back on the filter core 2 increases, the differential pressure between medium input pipe 3 and the medium efferent duct 2 increases gradually, and when this differential pressure reached a certain setting value, filter got into the backwash duty.The feedstock oil that has filtered utilizes self pressure reverse flow when filtering, and the solid particle of piling up on the filter core 2 is rinsed out.Above-described embodiment describes the preferred implementation of the filter cylinder of the utility model paraffin press; Be not that design and scope to utility model limits; Under the prerequisite that does not break away from the utility model scheme; Various external form modification and improvement that those skilled in the art make the technical scheme of the utility model all should fall into the protection domain of the filter cylinder of the utility model paraffin press.
