Abstract
The invention relates to a chemical raw material conveying pipeline, in particular to a safety shield for a chemical pipeline. The safety shield for the chemical pipeline comprises an upper housing and a lower housing, wherein edges of the upper housing and the lower housing are connected through bolts to form a cavity for accommodating a chemical pipeline connector; a gas leak detection tube is arranged on the upper housing; the upper housing is further provided with an exhaust pipe matched with the cavity; the exhaust pipe is connected with a suction fan; the upper housing is further provided with a check valve. The safety shield for the chemical pipeline has the benefits that the safety shield for the chemical pipeline can timely treat poisonous gas at a leaking position of the pipeline connector.
Description
Technical field
The invention belongs to industrial chemicals and transport pipeline, particularly Chemical Pipeline Protecting Jacket.
Background technique
In Chemical Manufacture, a lot of industrial chemicals can produce toxic gas in preparation, as contained element sulphur in ore, the gas containing element sulphur is had at leaching process, usually the gas containing element sulphur is toxic gas, and many toxic gases are soluble in water, so just be difficult to be separated toxic gas on source, only have and by pipeline, this part solution with toxic gas is transported in the lump, because pipeline needs to be connected by multistage could form a complete transport channel, be easy to appearance leakage in attachment portion.Once leak, toxic gas will gather around attachment portion, be easy to impact the health of staff.
Summary of the invention
The object of this invention is to provide a kind of can in time to the pipe safety cover that the toxic gas of pipeline junction leak processes.
In order to solve the problem, Chemical Pipeline Protecting Jacket provided by the invention, comprise upper encloser and lower encioser, described upper encloser and lower encioser edge are bolted, form the cavity of an accommodation chemical pipeline connecting head, described upper encloser is arranged the detecting tube being used for Leakage Gas, upper encloser is also provided with the outlet pipe with cavity connects, described outlet pipe connects a negative-pressure air fan, and upper encloser is also provided with one-way valve.
Upper encloser and lower encioser when in use, are buckled in the joint of chemical pipeline by the Chemical Pipeline Protecting Jacket of this programme, joint are formed a cavity, and the outlet pipe of upper encloser is connected fan, to the detection thing of filling in detecting tube for detecting gas.Detecting tube communicates with cavity, detaches in process by negative-pressure air fan to gas leakage, is maintained the air pressure balance in cavity by one-way valve.
The invention has the advantages that: by arranging safety enclosure at connector position, when chemical pipeline joint is leaked.First measured by the detection quality testing in detecting tube, once detecting tube detects the situation of leakage, open negative-pressure air fan and realize detaching cavity, emergency processing can be played before maintenance and leak the effect mentioning and detect gas.
As preferred scheme, between described upper encloser and lower encioser, be provided with Stamping Steel Ribbon; Make before not opening blower fan, can prevent gas from filling and connect punishment leakage.
As preferred scheme, described detecting tube is threaded with upper encloser; When needing in detecting tube to change the detection thing of filling, directly can screw off detecting tube, detection thing is changed.
Finally, described lower encioser is provided with liquid line, oozes out because chemical pipeline joint has a small amount of liquid, collects unified process by the liquid line of lower encioser.
Accompanying drawing explanation
Fig. 1 is the structural representation of Chemical Pipeline Protecting Jacket;
Fig. 2 is the sectional drawing of Chemical Pipeline Protecting Jacket.
Reference character is enumerated: upper encloser 1, one-way valve 2, chemical pipeline 3, detecting tube 4, outlet pipe 5, negative-pressure air fan 6, lower encioser 7, liquid line 8, cavity 9.
Embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
Chemical Pipeline Protecting Jacket as shown in Figure 1, comprises upper encloser 1 and lower encioser 7, and upper encloser 1 and lower encioser 7 edge are bolted, and forms the cavity 9 of accommodation chemical pipeline 3 connecting head; The detecting tube 4 that upper encloser 1 is arranged is for detecting Leakage Gas.Upper encloser 1 arranges tapped hole, detecting tube 4 connecting end arranges outside thread, detecting tube is threaded on upper encloser, upper encloser 1 is also provided with the outlet pipe 5 be communicated with cavity 9, described outlet pipe 5 connects a negative-pressure air fan 6, and upper encloser 1 is also connected with one-way valve 2, one-way valve 2 is communicated with cavity 9.
Upper encloser 1 and lower encioser 7 when in use, are buckled in the joint of chemical pipeline 3 by the Chemical Pipeline Protecting Jacket of this programme, joint are formed a cavity 9, and the outlet pipe 5 of upper encloser 1 is connected upper negative-pressure air fan 6; Detecting tube 4 communicates with cavity 9, to the detection thing of filling in detecting tube 4 for detecting gas.Detach in process by negative-pressure air fan 6 pairs of gas leakages, maintained the air pressure balance in cavity by one-way valve 2.
Stamping Steel Ribbon is provided with between upper encloser 1 and lower encioser 7; Make before not opening negative-pressure air fan 6, can prevent gas from filling joint and leak; Detecting tube 4 is threaded with upper encloser 1; When needing in detecting tube to change the detection thing of filling, directly can screw off detecting tube and detection thing is changed; Lower encioser 7 is provided with liquid line 8, is provided with filtering plug in described liquid line 8, oozes out because chemical pipeline 3 joint has a small amount of liquid, collects unified process by the liquid line 8 of lower encioser 7.
By arranging safety enclosure at connector position, when chemical pipeline joint is leaked.First measured by the detection quality testing in detecting tube, once detecting tube detects the situation of leakage, open negative-pressure air fan and realize detaching cavity, emergency processing can be played before maintenance and leak the effect mentioning and detect gas.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
