Description
Technical field
The utility model relates to purifying column field, specifically a kind of gas purification tower blowdown filter.
Background technology
Gas purification tower is the fuel of gas turbine and the purifier of blast furnace gas+coke-stove gas.This purifier is divided into multilayer, carries out multistage filtering to coal gas.Its purification process is that electric tar → slightly de-→ roots blower → gas cooler → essence is de-.Wherein thick de-and essence takes off this double-filtration, mainly allowing coal gas by being filled with the absorption filtering material such as coke and active carbon in this double-filtration layer.
After filtering material is when use one section, its adsorption filtration ability can decline.Existing processing mode be with in steam blowing purifying column by materials such as the tar of adsorption filtration, sulphur, benzene, naphthalenes, make these separating substances out with high temperature, thus allow the active carbon in purifying column regain adsorption capacity.In the process of steam blowing, need outlet diffusion valve, the import and export blowoff valve of opening purifying column.Discharge although point steam after large portion purges can pass through diffusion valve (height about 20 meters), still appoint and have quite a few can discharge through import and export blowoff valve, plant area's steam is filled the air, affects the sight line of field personnel.And these steam also with materials such as tar, sulphur, benzene, naphthalenes, are unfavorable for that staff's is healthy.
Utility model content
The utility model is intended to provide a kind of gas purification tower blowdown filter; The steam that this device can be discharged blowoff valve filters, condensation, thus reduces it to the sight line of staff and healthy impact.
A kind of gas purification tower blowdown filter; Comprise first level filtering device and two-stage filter;
Wherein first level filtering device comprises housing, and the top of one end of housing is provided with steam inlet, and middle part is provided with cooling water inlet, and other end sidewall is provided with osculum; Two groups of filters i.e. first group of filter and second group of filter is provided with, two groups of interlaced settings of filter in housing; First group of filter is fixed on case top, and it is highly less than 1/2nd of body height; Second group of filter is fixed on housing bottom, and it is highly greater than the difference of body height and filter height, and second group of filter is provided with through hole, is provided with cooling water in housing;
Two-stage filter, comprises a body, is filled with active carbon in body, and body one end is communicated with the other end of first level filtering device; The other end of body is closed and is arranged draining valve.
Utility model works principle:
By injecting the aqueous solution of certain volume in housing, by the import and export blowoff valve of purifying column access steam inlet, steam is through every block filter time, resistance increases, due to Action of Gravity Field, the materials such as the tar in water vapour are stayed on dividing plate, and part water vapour contacts with cooling water, become condensed water and stay in cooling water; Finally can be discharged into phenol pond by osculum; Uncooled gas can filter through active carbon more further, and the residual harmful substance be mingled with is issued to phenol puddle by draining valve after filtering again.
The utility model, by the setting of dual stage filter apparatus, can make the condensation in device of most steam, reduces the discharge of steam, thus reduces its impact on the sight line of staff; Even if finally have the uncooled steam of sub-fraction to discharge also be through charcoal absorption filtration, less to Health Impact.
Further, described steam inlet is provided with air inlet pipe, and air inlet pipe port is located at below liquid level.
First through cooling water washing, more steam-condensation can be made after steam enters.
Further, described two-stage filter and first level filtering device are for being threaded or clamping.
Be convenient to the disassembly, cleaning of two filters.
Further, the height of described cooling water inlet and osculum is 1/2nd of body height.
Because the cooling water in housing needs timing to change, and in order to vapor pressure too large, cause cooling water to flow into two-stage filter, the liquid level of cooling water can not higher than the bottom of first group of filter.And when changing water, be not easy to the height controlling liquid level, be 1/2nd of body height by the height of entrance and osculum, the aqueous solution in housing just can be prevented too much.Directly osculum is opened during replacing; During cooling, liquid level is at most 1/2nd of body height, can not more than the bottom of first group of filter.
Further, the body of described two-stage filter is provided with charging hole and dumping pit.
This design is for the ease of changing active carbon.
Further, the junction of first level filtering device and two-stage filter is provided with steel wire.
Can prevent active carbon from entering first level filtering device, and steel wire mesh is more, is convenient to steam and passes through, not easily result in blockage.
Further, be radially provided with a division board in described body, body be divided into two chambers, described active carbon is filled in a chamber of first level filtering device; Another chamber wall is provided with air bleeding valve.
The design of two chambers is convenient to active carbon to be fixed in certain space, prevents active carbon from blocking draining valve, and meanwhile, the setting of air bleeding valve, the air pressure being convenient to two-stage filter is equal with the external world, prevents inner formation negative pressure, not easily condensation.
