Abstract
The utility model provides a composite sewage filter of a delayed coking unit. The composite sewage filter can automatically switch different filter nets according to the content of fine coke of cold-cut coke water, and thus the using effect of the composite sewage filter is improved. The composite sewage filter of the delayed coking unit comprises a housing with a water inlet and a water outlet and is characterized in that the water inlet and the water outlet are communicated with each other by several independent water channels, wherein each water channel is internally provided with an electric control valve and a filter net, the water inlet is provided with a sensor for sensing the content of the fine coke of the cold-cut coke water, the sensor and the electric control valves are connected with one control unit; the specifications of the filter nets in the different water channels are different. In the working process, the sensor is used for transmitting the sensed information about the content of the fine coke of the cold-cut coke water to the control unit and the control unit is used for controlling the opening of the different electric control valves according to the different contents of the fine coke, thereby selecting the filter net of the proper specification.
Description
Technical field
The utility model belongs to the petrochemical technology field, specially refers to a kind of compound sewage filter of delayed coking unit.
Background technology
Delayed coking unit in petrochemical industry adopts hydraulic decoking, when operation, can produce the sewage that contains in a large number coke powder, i.e. cold-cut water.Because this cold-cut water recycles, therefore the processing quality of cold-cut water is directly connected to follow-up decoking effect.Due in different production processes, the coke powder content difference of cold-cut water, therefore only adopt single filter plant, if the mesh of screen pack is larger, although flow velocity is very fast, but the problem that there will be poor filtration effect, if the mesh of screen pack is smaller, the flow velocity chance of cold-cut water is slower, can not meet follow-up decoking process, the susceptible to plugging problem of screen pack also easily occurs, have a strong impact on the result of use of effluent filter.
The utility model content
The purpose of this utility model is the compound sewage filter that proposes a kind of delayed coking unit, this kind of compound sewage filter different screen pack that can automatically switch according to the coke powder content of cold-cut water, thus improved the result of use of compound sewage filter.
The compound sewage filter of delayed coking unit of the present utility model comprises the housing that is provided with water inlet, delivery port, key is between described water inlet, delivery port by some independently water channel connections, be provided with electric control valve and screen pack in every water channel, described water inlet is provided with the sensor of the coke powder content for surveying cold-cut water, and described sensor and each electric control valve all are connected with a control module; Screen pack specification difference in described different water channel.
In the course of the work, sensor sends the coke powder content information of the cold-cut water that detects to control module in real time, control module is controlled different electric control valves according to different coke powder content and is opened, thereby make cold-cut water when its coke powder content is different, adopt the screen pack of different size to filter, when the coke powder content of cold-cut water is larger, adopt the screen pack that mesh diameter is larger to filter, when the coke powder content of cold-cut water hour, adopt the screen pack that mesh diameter is less to filter, certainly, can also open several water channels is filtered simultaneously, thereby guarantee the flow velocity of cold-cut water and good filter effect.
Further, the water channel at the screen pack place of the described mesh diameter maximum in line mouth set with housing communicates, and in line mouth is connected with sedimentation basin, can avoid like this cold-cut water that coke powder content is larger to enter into follow-up decoking process.
Further, described every water channel is provided with breast hole at the upstream position of screen pack, with the coke powder gathered for discharge.
The compound sewage filtration device structure of delayed coking unit of the present utility model is simple, convenient to be made, and according to the coke powder content of the cold-cut water different screen pack that automatically switches, thereby has improved the result of use of compound sewage filter, has good practicality.
The accompanying drawing explanation
Fig. 1 is the structural representation (depression angle) of compound sewage filter of the delayed coking unit of embodiment 1.
The specific embodiment
Below contrast accompanying drawing, by the description to embodiment, the specific embodiment of the present utility model is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and operation principle etc.
Embodiment 1:
As shown in Figure 1, the compound sewage filter of the delayed coking unit of the present embodiment comprises the housing 9 that is provided with water inlet 1, delivery port 2, key is between described water inlet 1, delivery port 2 by some independently water channel 3 connections, be provided with electric control valve 4 and screen pack 5 in every water channel 3, every water channel 3 is provided with breast hole 6 at the upstream position of screen pack 5; Described water inlet 1 place is provided with the sensor 7 of the coke powder content for surveying cold-cut water, and described sensor 7 and each electric control valve 4 all are connected with the control module that a single-chip microcomputer is made; The specification different (control module not shown in FIG.) of the screen pack 5 in described different water channel 3.
When sensor 7 can utilize the coke powder content of cold-cut water different, the principle that its light reflectance and refractive index are different, adopt photoelectric sensor to make, and repeats no more herein.
In the course of the work, sensor 7 sends the coke powder content information of the cold-cut water that detects to control module in real time, control module is controlled different electric control valve 4 according to different coke powder content and is opened, thereby make cold-cut water when its coke powder content is different, adopt the screen pack 5 of different size to filter, when the coke powder content of cold-cut water is larger, adopt the screen pack 5 that mesh diameter is larger to filter, when the coke powder content of cold-cut water hour, adopt the screen pack 5 that mesh diameter is less to filter, certainly, can also open several water channels 3 is filtered simultaneously, thereby guarantee the flow velocity of cold-cut water and good filter effect.
Can regularly open breast hole 6, be discharged by breast hole 6 accumulating in the front coke powder of screen pack 5.
The water channel 3(at screen pack 5 places of described mesh diameter maximum i.e. the water channel of below in figure) the in line mouth 8 set with housing 9 communicate, in line mouth 8 is connected with sedimentation basin, can avoids like this cold-cut water that coke powder content is larger to enter into follow-up decoking process.
