Description
Technical field
The utility model relates to a kind of temperature-sensitive pressure-sensitive explosion-protection equipment.
Background technology
Reactor is one of common equipment of oil, petrochemical industry, chemical industry, coal chemical industry, the product needed for some raw material after chemical reaction is produced.A lot of chemical reaction is exothermic reaction, causes reaction system temperature and pressure to raise.Temperature and pressure is the major parameter of reaction system.Once raw material feeding, cooling system etc. go wrong, when rate of heat release is greater than rate of heat transfer, just easily reacts out of control, cause reaction temperature runaway, then cause the temperature and pressure of reaction system sharply to raise.Pressure sharply raises and can not be effectively controlled, and causes pressure to exceed certain limit, cause the destruction of normal operation, even catalyst burnt, initiator reactor blast.
One of measure of reply runaway reaction is on reactor, arrange rupture pressure disc or rupture disk.CN03150258.X provides a kind of reaction unit for implode anti-in bulk technique.It installs a set of reactor immediately below the feeder of airtight reaction vessel internal upper part, or be connected in series one or more reactor successively from top to bottom again under it, under the reactor of most next stage, have conveyer belt and finished bin.Reactor is imported and exported by cylinder, support roller, scraper, guide wheel and heat transferring medium and is formed.But install a kind of explosion-protection equipment separately, once malfunctioning, consequence is serious.Therefore, security is poor, and the easy contaminated environment of material of blast release.
The utility model solves this problem targetedly.
Utility model content
Technical problem to be solved in the utility model is the problem of low, the contaminated environment of safety coefficient in prior art, provides a kind of new temperature-sensitive pressure-sensitive explosion-protection equipment.This device has safety coefficient advantage high, free from environmental pollution.
For solving the problem, the technical solution adopted in the utility model is as follows: a kind of temperature-sensitive pressure-sensitive explosion-protection equipment, comprise the fusible plug (2) that fusible alloy is housed, rupture disk (3), by-pass valve control (4), relief pipeline (5), buffer container (6), rupture disk (3) and fusible plug (2) are arranged on reactor (1) wall, it is characterized in that rupture disk (3) is connected with relief pipeline (5) respectively by pipeline in parallel with fusible plug (2), relief pipeline (5) other end is connected with buffer container (6), relief pipeline (5) is provided with by-pass valve control (4).
In technique scheme, preferably, described rupture disk (3) is positive arch form or counter-arch shaped.
In technique scheme, preferably, described fusible plug (2) cock body has bellmouth, stepped hole or screwed hole to install fusible alloy.
In technique scheme, preferably, described rupture disk (3) and fusible plug (2) are arranged on the wall of reactor (1) gas phase portion.
Reactor temperature and pressure are associations.Pressure raises along with the rising of temperature usually.The present invention can the angle of action from response temperature and response pressure, devises temperature-sensitive (fusible plug), pressure-sensitive (rupture disk) explosion-protection equipment.Its general principle is, when temperature reaches critical-temperature, the fusible alloy of the fusible plug in temperature-sensitive pressure-sensitive explosion-protection equipment melts, and the space stayed after the pressure of reaction system is melted by fusible plug fusible alloy and the pipeline of connection are discharged in buffer container and go; And when pressure reaches critical pressure, rupture disk breaks, the space stayed after the pressure of reaction system is broken by rupture disk and the pipeline of connection are discharged in buffer container and go.
This patent relates to installs temperature-sensitive (fusible plug), pressure-sensitive (rupture disk) explosion-protection equipment in the reactor that may exist temperature runaway simultaneously, when temperature and pressure reaches critical-temperature, pressure, rupture disk breaks, fusible alloy in temperature-sensitive fusible plug melts, pressure in reactor is discharged, simultaneously be disposed to buffer container via pipeline thing of releasing, avoid causing atmosphere pollution, achieve good technique effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of device described in the utility model.
In Fig. 1,1 is reactor; 2 is fusible plug; 3 is rupture disk; 4 is by-pass valve control; 5 is relief pipeline; 6 is buffer container.
Below by embodiment, the utility model is further elaborated, but is not limited only to the present embodiment.
Detailed description of the invention
[embodiment 1]
On device as described in Figure 1, rupture disk (3) and fusible plug (2) are arranged on reactor (1) wall, it is characterized in that rupture disk (3) is connected with relief pipeline (5) respectively by pipeline in parallel with fusible plug (2), relief pipeline (5) other end is connected with buffer container, and relief pipeline (5) is provided with by-pass valve control (4).
Rupture disk (3) is domed rupture disk, and described fusible plug (2) cock body has bellmouth, and to load fusible alloy, fusible alloy is the alloy made with low-melting-point metal elements such as bismuth, lead, tin and cadmiums.The fusing point of fusible alloy can be realized by the content of adjustment low-melting-point metal element according to causing the critical-temperature of temperature runaway.When the temperature in reactor (1) reaches critical-temperature, the fusible alloy of the fusible plug (2) in temperature-sensitive pressure-sensitive explosion-protection equipment melts, and the space stayed after the pressure of reaction system is melted by fusible plug (2) fusible alloy and the relief pipeline (5) of connection are discharged in buffer container (6) and go; And when pressure reaches critical pressure, rupture disk (3) breaks, the relief pipeline (5) of the space stayed after the pressure of reaction system is broken by rupture disk and connection is discharged in buffer container (6) and goes.
[embodiment 2]
According to the condition described in embodiment 1, just rupture disk (3) is counter-arch shaped blasting piece, and fusible plug (2) cock body has stepped hole.
