Abstract
The utility model relates to a wellhead device for bioremediation of a contaminated land. The wellhead device comprises a high-density polyethylene (HDPE) pipe, a ball valve, a sealing nut, a butterfly valve, a flow meter, a flange and a Bauer joint; the HDPE pipe is respectively connected with a gas pipe and a perfusion pipe; the ball valve is arranged on the gas pipe; the sealing nut, the butterfly valve and the flower meter are arranged on the perfusion pipe; and the Bauer joint is connected to one end of the perfusion pipe. The gas pipe and the perfusion pipe are organically combined together, so that the wellhead device like a well can have two purposes, realizes multiple purposes in one well and reduces the number of the required well. By connection of the flange, the wellhead device can be flexibly detached, so that the reutilization rate is increased. The work amount is reduced, the cost is saved, the working strength and the working difficulty are reduced, and the wellhead device is convenient to install and use.
Description
[technical field]
The utility model relates to a kind of well head, is specifically related to the dual-purpose wellhead assembly that is used for the contaminated land biological restoration of a kind of air water, belongs to the pipeline engineering technical field, mainly applies to contaminated land, environment remediation engineering.
[background technology]
The soil can produce very large harm to the surrounding enviroment and the inhabitation crowd in soil after being polluted by materials such as organic matter, heavy metals.The household refuse landfill sites of China is after it closes; And after industrial enterprise's resettlements such as chemical industry, pharmacy, coking; The organic matter that exists in the soil can produce multiple secondary pollutions such as percolate, foul gas, poisonous microorganism; Also can occupy a large amount of land resource, thereby and cause its degradation rate very slow because organic pollutant component is complicated, the needs about 100 years of degrade fully; And the heavy metal pollution strong toxicity belongs to permanent pollution.Utilization aerobe reactor technology is repaired the soil of quilt organic matter and heavy metal pollution, strengthens biological the ventilation and increase pollution water supply in media, helps quickening the decomposition rate of microorganism to organic matter, makes it in 2-3, accomplish degraded fully; And under action of microorganisms, the heavy metal form changes, and toxicity also can correspondingly reduce.
And utilize aerobic bioreactor technology to need artificially regulate to the moisture in the contaminated land, air content, process mainly comprise bleed, gas injection and three systems of water filling.And in order to realize that three systems perfectly cooperate and the optimal conditions that reaches microbial action fast; Be employed in different depth more and beat the mode of vertical shaft and carry out, but if three systems dig a well respectively, the well number can be very many in the contaminated land governance process; Both took a lot of work, cost also can be very high.
For solving the problems of the technologies described above, necessary a kind of structure improved wellhead assembly that is used for the contaminated land biological restoration that has is provided, to overcome said defective of the prior art.
[utility model content]
For addressing the above problem; The purpose of the utility model is to provide a kind of wellhead assembly that is used for the contaminated land biological restoration of bleeding with two kinds of functions of water filling that has concurrently; It has realized the merging of extraction well and water injection well; Reduced treatment cost and engineering time,, realized that the perfection of two kinds of functions is merged simultaneously through the control of valve.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: a kind of wellhead assembly that is used for the contaminated land biological restoration, and it comprises HDPE pipe, ball valve, sealing nut, butterfly valve, flowmeter, flange and Bauer joint; Wherein, on said HDPE pipe, be connected with appendix and woven hose respectively; Said ball valve is installed on the appendix; Said sealing nut, butterfly valve and flowmeter are installed on the woven hose; Said Bauer joint is connected in an end of woven hose.
The wellhead assembly that is used for the contaminated land biological restoration of the utility model further is set to: said appendix and woven hose are and are horizontally disposed with, and woven hose is positioned at the appendix top.
The wellhead assembly that is used for the contaminated land biological restoration of the utility model further is set to: said HDPE pipe below is connected with a vertical tube through a flange.
The wellhead assembly that is used for the contaminated land biological restoration of the utility model further is set to: described wellhead assembly different parts is to connect through flange.
Compared with prior art, the utlity model has following beneficial effect: the wellhead assembly that is used for the contaminated land biological restoration of the utility model organically combines appendix and woven hose, makes a well that two kinds of purposes can be arranged; Realized that a well uses more; Reduced the quantity of required well, this had both reduced quantities, had practiced thrift cost; Working strength and difficulty, more convenient installation and use have also been reduced simultaneously.Through the data analysis that the sensor that flowmeter, sealing nut are connected obtains, carry out intermittence to bleeding with water filling with ball valve and butterfly valve and control, realized the cooperation of two-phase fluid function.And a plurality of different parts such as vertical tube, well head top connection woven hose all are to connect through flange bottom the well head, are easy to dismounting, have increased the recycling rate of waterused of wellhead assembly.
[description of drawings]
Fig. 1 is the structural representation of the wellhead assembly that is used for the contaminated land biological restoration of the utility model.
[specific embodiment]
See also shown in the Figure of description 1; The utility model is a kind of wellhead assembly that contaminated land is repaired that is used for; (component-assembled such as (High Density Polyethylene, high density polyethylene (HDPE)) pipe 1, ball valve 2, sealing nut 3, butterfly valve 4, flowmeter 5 and Bauer joint 6 form by HDPE for it.
Wherein, said HDPE manages 1 below and is connected with a vertical tube 8 through a flange 7, and this vertical tube 8 is the gas-liquid common conduit.On said HDPE pipe 1, be connected with appendix 11 and woven hose 12 respectively, woven hose 12 also is connected through flange 7 with HDPE pipe 1.Different parts connects through flange 7, can increase the recycling rate of waterused of wellhead assembly.Said appendix 11 is with woven hose 12 and is horizontally disposed with, and woven hose 12 is positioned at the top of appendix 11.
Further, said ball valve 2 is installed on the appendix 11, and it is used to control appendix 11 and whether bleeds.Said sealing nut 3, butterfly valve 4 and flowmeter 5 are installed on the woven hose 12, and whether said butterfly valve 4 is used to control in the woven hose 12 fluid injections.And the work life period of appendix 11 and woven hose 12 is poor, controls ball valve 2 and butterfly valve 4 respectively through the generation signal of the sensor that connects on the sealing nut, does not produce the phase mutual interference.
Said Bauer joint 6 is connected in an end of woven hose 12, is used to connect infusion tube.
Said sealing nut 3 is main with being used to that humiture, gas sensor (not shown) device of etc.ing are installed, and the seal of gas in utilizing sealing nut 3 modes to connect to guarantee to manage, thus the accuracy of realization data.Said flowmeter 5 is used for the transmission of fluid flow rate signal, thereby pusher flowmeter is generally adopted in the interpolation of control amount of liquid.
The above specific embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection domain of this creation.
