Abstract
The utility model provides a hot type fibrous filter component is mixed to coil pipe mixes the heating spiral including fibrous filter layer, porous support chassis, hollow metal in its device. The metal is mixed the heating spiral and is installed inside porous skeleton to make the heat transfer effect better rather than the contact, the fibrous filter layer is made on porous skeleton by the winding of activated carbon fiber felt. The utility model discloses a filter element is applicable to air purification equipment, is used for adsorbing the organic component that contains return value to reach the palingenetic effect of desorption through the evacuation and the condition of mixing hot dielectric heating.
Description
Technical field
Hot type fiber filter element mixed by a kind of coil pipe that the utility model relates in filter element field, specifically be applicable to the filter core of the engineering fields such as purification of air, chemical emission improvement, petroleum vapor recovery, be used for adsorbing the volatile organic component with recovery value, and reach the effect of desorption and regeneration by the condition vacuumizing and mix thermal medium heating.
Background technology
Known being used for purifying air, VOC administers, in device for recovering oil and gas, generally adopt one or more group technologies in condensation, absorption and sorption to process.
Sorbing material the most frequently used in absorbing process is granular activated carbon, and active carbon, when reality is filled, due to the impact of self granular size, shape and other condition, often exists void among particles between particle.The connection to each other of these spaces just creates gas circuit short circuit.Gas pollutant, when by active carbon bed, preferentially can pass, result in activated carbon filtration precision not high from these short circuits.And along with the appearance of " GB31570-2015 petroleum refining industry pollutant emission standard ", the defect that active carbon cannot overcome self cannot meet the latest requirement of new national standard.And activated carbon fiber is the widely used Powdered Activated Carbon that continues, the third generation novel absorption material after granular activated carbon is a kind of novel absorption material just grown up in recent years.Activated carbon fiber diameter is at 5 ~ 20um, and specific area is on average at about 1000 ~ 1500m2/g, and average pore size is at 1.0 ~ 4.0nm, and micropore is uniformly distributed in fiber surface, and fast for the absorption small organic molecule matter rate of adsorption, adsorption rate is high, easy desorption.
At present, the activated carbon fiber through reporting, as renovation process during sorbing material, is generally by backwash and regenerations such as steam, hot-air, hot nitrogens.During regeneration, by the reverse blow of medium, the organic component being adsorbed on activated carbon fiber micropore is taken out of, and then realize the recycling of organic component by the step such as condensation, water-oil separating.This regeneration, be that the organic component of absorption is mixed with blowback medium, follow-up when will reclaim, also will carry out both separation, this increases energy consumption undoubtedly and the organic component purity of recovery is reduced.
And on the other hand, by the organic component adsorbed, all be there is effumability, be the desorption and regeneration being conducive to activated carbon fiber under the condition of heating.
real novel content
The purpose of this utility model is the deficiency solving above technology, provides a kind of conduction being conducive to heat, makes the better coil pipe of activated carbon fiber desorption effect mix hot type fiber filter element.
The technical solution of the utility model is:
Hot type fiber filter element mixed by a kind of coil pipe, comprises stephanoporate framework and around the filter course outside stephanoporate framework, what in stephanoporate framework, arrange hollow mixes hot coil, and described filter course is activated carbon fibre filtering layer.
Such scheme comprises further:
Described stephanoporate framework is tubular, and described hot coil of mixing is embedded in stephanoporate framework inside in the shape of a spiral, and the two ends of mixing hot coil are separately positioned on bone porous two ends.
Described stephanoporate framework is tubular, and described hot coil of mixing is embedded in stephanoporate framework inside in the shape of a spiral, the one end of mixing hot coil turn back after with the other end with being arranged on bone porous one end.
Described activated carbon fibre filtering layer is that active carbon fiber felt is centered around outside stephanoporate framework by canoe.This element comprises: the spiral metal of fibrous filter layer, stephanoporate framework, hollow mixes hot coil.
The Advantageous Effects that the utility model has is:
(1) commute VOC absorption precision is high;
(2) desorption process only has energy exchange, does not have mass exchange, therefore ensure that organic purity is reclaimed in desorb, it also avoid the operation of the water-oil separating that wet method desorption brings;
(3) pollution-free to heat medium, after heat exchange, heat medium can reuse or waste heat recycling.
Accompanying drawing explanation
Fig. 1 is that hot type fiber filter element schematic diagram mixed by the utility model coil pipe.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, hot type fiber filter element mixed by a kind of coil pipe, and this element comprises: the spiral metal of fibrous filter layer 5, stephanoporate framework 3, hollow mixes hot coil 2.Metal is mixed hot coil 2 and is arranged on stephanoporate framework 3 inside; Fibrous filter layer 5 is wrapped on stephanoporate framework obtained by active carbon fiber felt.
Described stephanoporate framework (steel, copper or pottery etc.) 3 is in tubular, described metal is mixed hot coil 2 and is embedded in stephanoporate framework 3 inside in the shape of a spiral, the two ends (medium inlet 1 and media outlet 4) that metal mixes hot coil 3 are separately positioned on the two ends of stephanoporate framework 3, or the one end of mixing hot coil turn back after with the other end with being arranged on bone porous one end.
Described fibrous filter layer 5 is centered around outside stephanoporate framework 3 by canoe for active carbon fiber felt.
Application Example
Coil pipe of the present utility model is mixed hot type fiber filter element to be arranged in pressure-resistant seal container, and the air exit of container is connected to stephanoporate framework one end, and air inlet is facing to acf layer.Pass into normal temperature organic exhaust gas at air inlet, waste gas is through acf layer, and organic component is adsorbed by fibrage, and surplus air component is discharged from air exit with purified gas form.After fibrage absorption is saturated, air exit is closed, open vavuum pump to vacuumize from air inlet container, when container inner pressure is negative pressure-10 ~ 80kPa, hot coil is mixed to metal and passes into the heat medium high-temperature steam of 0.1MPa (used herein be), the organic component be attached in carbon fiber hole is departed from, thus makes filter element reach the effect of holomorphosis.
This approach avoid the operation of the water-oil separating that wet method desorption brings, reclaim adsorbate fast more convenient.Medium temperature after companion's heat is also higher, can consider that waste heat recycles.
