Abstract
The utility model relates to a chlorine gas special fire arrestor, and belongs to the field of a flame blocker which permits gas to pass through rather than the flame or burst wave, and the chlorine gas special fire arrestor is composed of a fire arrestor shell body provided with a contact flange. The utility model has the technical key points that the fire arrestor shell body is composed of two parts in a buckling way, wherein, the section of the two parts is crateriform, pottery fire retardant plates provided with millipores and a polyfluortetraethylene fire retardant net are respectively embedded and arranged in the fire arrestor shell body, and the polyfluortetraethylene fire retardant net is positioned between the pottery fire retardant plates provided with millipores. The chlorine gas special fire arrestor provided by the utility model is invented to solve the problem that the chlorine gas special fire arrestor is lack in the prior art, and eliminate the security hidden troubles in the process of the chlorine gas transportation.
Description
Technical field
The utility model belong to allow gas by but the flame block device field that do not allow flame or blast wave to pass through specifically is the special-purpose spark arrester of a kind of chlorine.
Background technology
In the gas course of conveying of chemical industry,, therefore just need in the course of conveying of gas, install various fire-retarding devices additional because many gases are inflammable and explosive.Though chlorine is under normal circumstances nonflammable, not enough or when being doped with inflammable gas such as hydrogen in purity, there has been inflammable and explosive potential safety hazard equally.And chlorine is in production and course of conveying, because self characteristics has the place that is different from other gases again, the spark arrester that other air shooter lines are used can not directly be applied on the chlorine feed-line, for this reason, need satisfy the needs that chlorine is carried at the spark arrester of chlorine design specialized.
The utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, compact, easy for installation, and good flame retardation effect is specially at the special-purpose spark arrester of the chlorine of chlorine pipeline transfer designs.
For achieving the above object, the utility model is achieved through the following technical solutions:
It is the special-purpose spark arrester of a kind of chlorine, comprise the spark arrester housing that has connecting flange, the present technique main points are that the spark arrester housing is that two parts of funnel-shaped structure fasten and to form by section, in the spark arrester housing respectively setting-in have the ceramic fire-proof plate and the polytetrafluoroethylene (PTFE) back-fire relief net of micropore, polytetrafluoroethylene (PTFE) back-fire relief net is between the micropore ceramics fire-proof plate.
In order further to strengthen the back-fire relief effect, the connection place that spark arrester housing two parts fasten adds the ceramic fire-proof plate that has micropore.
In addition, for the ease of producing and installing, polytetrafluoroethylene (PTFE) back-fire relief net is group's flocculent structure, and polytetrafluoroethylene (PTFE) back-fire relief net just can add or reduce according to the size in space in the spark arrester housing like this, carries the needs of back-fire relief requirement to satisfy chlorine.
Appearance of the present utility model has solved the deficiency that does not have the special-purpose spark arrester of chlorine in the prior art, has eliminated the potential safety hazard in the chlorine course of conveying.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: the utility model example structure schematic diagram.
The specific embodiment
As shown in Figure 1, the special-purpose spark arrester of this chlorine, comprise the spark arrester housing 1 that has connecting flange, the present technique main points are that spark arrester housing 1 is that two parts of funnel-shaped structure fasten and to form by section, in the spark arrester housing 1 respectively setting-in have the ceramic fire-proof plate 2 and the polytetrafluoroethylene (PTFE) back-fire relief net 3 of micropore, polytetrafluoroethylene (PTFE) back-fire relief net 3 is between the micropore ceramics fire-proof plate, because of spark arrester housing 1 is that two parts of funnel-shaped structure fasten and to form by section, therefore ceramic fire-proof plate 2 and polytetrafluoroethylene (PTFE) back-fire relief net 3 are respectively by two ceramic fire-proof plate 2-1 independently, 2-2 and polytetrafluoroethylene (PTFE) back-fire relief net 3-1 and 3-2 setting-in successively form.
In order further to strengthen the back-fire relief effect, the connection place that spark arrester housing 1 two parts fasten adds the ceramic fire-proof plate 4 that has micropore.
In addition, for the ease of producing and installing, polytetrafluoroethylene (PTFE) back-fire relief net 3 is group's flocculent structure, and polytetrafluoroethylene (PTFE) back-fire relief net 3 just can add or reduce according to the size in space in the spark arrester housing like this, carries the needs of back-fire relief requirement to satisfy chlorine.
Appearance of the present utility model has solved the deficiency that does not have the special-purpose spark arrester of chlorine in the prior art, has eliminated the potential safety hazard in the chlorine course of conveying.
Claims (3)
1, the special-purpose spark arrester of a kind of chlorine, comprise the spark arrester housing that has connecting flange, it is characterized in that the spark arrester housing is that two parts of funnel-shaped structure fasten and to form by section, in the spark arrester housing respectively setting-in have the ceramic fire-proof plate and the polytetrafluoroethylene (PTFE) back-fire relief net of micropore, polytetrafluoroethylene (PTFE) back-fire relief net is between the micropore ceramics fire-proof plate.
2, the special-purpose spark arrester of chlorine according to claim 1 is characterized in that the connection place that spark arrester housing two parts fasten adds the ceramic fire-proof plate that has micropore.
