The control of amount.
Background technology
The compression of alkali chemical industry enterprises chlorine in the prior art more uses turbo-compressor.The work of turbo-compressor
Process：Enter chlorine gas compressor group by dry chlorine, it rotates produced centrifugal force to chlorine by means of the high speed of impeller
Air-flow work done, is allowed to obtain kinetic energy and static energy, so that cl gas flow pressure rise, 0.150MPa is compressed to by chlorine.Then
Deliver to downstream user.
Wherein, turbo-compressor gland seal device uses labyrinth seal, but only one section great runner of resistance of labyrinth seal.
Effectively to prevent chlorine from leaking, employ and take out, inflate the labyrinth seal form being combined.Therefore turbo-compressor must be used and contained
The wet nitrogen less than 50PPM is sealed, and sealed position is bearing.As shown in Fig. 2 sealing nitrogen by turbo-compressor
Tail chlorine in pipe 1 is directly discharged into useless chlorine absorption system.
The course of work of useless chlorine absorption system is as described below.The waste gas containing chlorine is sent to useless chlorine during chlor-alkali production
Absorption tower.Waste gas containing chlorine includes the sealing nitrogen containing chlorine that turbo-compressor is discharged or leaked.Circulating pump
Absorbing liquid containing 15-20% concentration alkali in retort is squeezed into after cooler cooling, absorbing liquid enters useless chlorine absorption tower simultaneously
Sprayed from absorbing liquid distributor.Waste gas containing chlorine, which is passed through from bottom, enters useless chlorine absorption tower, and filler surface with
Absorbing liquid counter current contacting, reaches the purpose of absorption.Absorbing liquid, which is absorbed in waste gas, forms the inflow of semi-finished product liquid instead after chlorine
Answer and continue circular response in tank, until it becomes stopping reaction after finished product.The tail gas formed after waste gas dechlorination is straight through air-introduced machine
