Description

A kind of piston type chlorine gas compressor and liquifier thereof

One, technical field:

The utility model relates to the machinery that chlorine liquefies under high normal pressure and temperature, especially a kind of piston type chlorine gas compressor and liquifier thereof.

Two, background technique:

The chlorine that chlor-alkali enterprise electrolysis production goes out mostly will be handled its liquefaction, with convenient transportation.Liquefaction process is many to be refrigerant with freon, the pressure that chlorine gas pump is pressurized to chlorine 0.2MPa---0.3MPa liquefies under the low temperature about-30 ℃, and also useful ammonia---calcium chloride indirect refrigeration makes chlorine gas liquefaction.Its apparatus and process mostly exists energy consumption height, equipment multiple footprint big, complicated operation, and maintenance load is big, the expense height, leakage problem is difficult to administer, and environmental pollution serious problems, especially freon are disabled gradually in the world.

Three, summary of the invention:

The purpose of this utility model provides a kind of piston type chlorine gas compressor and the liquifier thereof that chlorine liquefies under high normal pressure and temperature, it has solved the technical problem that exists in the chlorine gas liquefaction, the purpose of this utility model is to realize like this, it is by belt pulley, body, bent axle, connecting rod, crosshead, piston rod, muffler, cylinder block, the one-level cylinder, first stage piston, the one-level Aspirating valves, the one-level outlet valve, cylinder head, the secondary Aspirating valves, the secondary outlet valve, secondary cylinder, second piston, piston rod packing, scraper ring, the import of piston compressor one-level, the piston type chlorine gas compressor, interstage cooler, liquifier, the liquifier chlorine inlet, the liquid chlorine outlet, the waste chlorine outlet, the cooling water outlet and inlet pipe is formed by connecting, crankshaft installed is in body, belt pulley is installed in an end of bent axle, connecting rod is installed on bent axle, crosshead is installed successively, piston rod and piston; In body upper cylinder block and cylinder head are installed, cylinder is installed in cylinder block, piston is housed in the cylinder; One-level Aspirating valves, one-level outlet valve are installed in the cylinder head; The other end at bent axle is equipped with connecting rod, and crosshead, piston rod and piston are installed successively; In body upper cylinder block and cylinder head are installed successively, secondary cylinder is installed in cylinder block, second piston is housed in the secondary cylinder; Secondary Aspirating valves, secondary outlet valve are installed in the cylinder head; Piston rod packing and scraper ring are installed in body; In a side of cylinder head the one-level import of piston compressor is arranged, its opposite side is outlet; The piston type chlorine gas compressor is fixed on the base; One end of muffler is installed in the top of body one end, and the other end of muffler is connected with process pipe; The outlet of secondary import and secondary is arranged, outlet of piston compressor one-level and the middle interstage cooler that is being connected of piston compressor secondary inlet pipeline on the cylinder cap of compressor; The outlet of piston compressor secondary is connected with the liquifier chlorine inlet by pipeline; The liquid chlorine outlet is positioned at liquifier bottom one side, and the waste chlorine outlet is positioned at top one side of liquifier; The cooling water outlet and inlet pipe is positioned at an end of liquifier.

Bent axle rotates under the drive of motor, and connecting rod becomes rotatablely moving of bent axle the to-and-fro motion of crosshead, piston rod and piston; Piston is done in cylinder when the axle stroke, suck chlorine by Aspirating valves, piston is when doing from the axle stroke, compression chlorine is discharged through outlet valve, after cooling by interstage cooler, enter the next stage cylinder again and compress, chlorine just enters into finally to liquefy in the liquifier and is liquid chlorine after discharging; Chlorine liquefier is a kind of multipass shell-and-tube cooler, and chlorine can be condensed into liquid chlorine with gaseous chlorine gas as long as feed the normal temperature industry water in tube side after entering the shell side of liquifier under certain pressure.

The micro-chlorine that compressor spills from piston ring when work is pooled to the upper space of body, drawing back access production system by the muffler that is provided with is on the pipeline of little negative pressure, solve compressor effectively and outwards revealed the difficult problem of chlorine, the working life of filler will have been prolonged greatly, to realize zero breakthrough of revealing of rod seal filler; Also will significantly reduce the number of times of revealing parking maintenance because of filler; Also save the problem of piston rod packing with inert gas seal.
