Description
Technical field
The present invention relates to a kind of liquid chlorine transporting system of producing haloflex.
Background technique
Liquid chlorine is yellowish green oily liquids, poisonous, and it is lowpressure liquid gas, and for the liquid condition that keeps liquid chlorine need to be controlled at storage chlorine tank temperature below 35 ℃, storage chlorine tank periphery needs coating thermal insulating material, in case liquid chlorine vaporization becomes gas form.Mostly domestic production haloflex is to adopt logical liquid chlorine.There is enterprise directly to use small-sized liquid chlorine cylinder, have the enterprise of large-scale liquid chlorine holding vessel to adopt canned motorpump or Under Water Pumps that liquid chlorine is transported to reactor.Because chlorine is very active element, can and most elements (or compound) react, in the process of carrying at liquid chlorine can and pipeline or the pump housing in the material generation impurity that reacts, in the pump housing, cause obstruction, thereby affect the normal work of pump, affect the continual and steady output of liquid chlorine, chlorination reaction is exerted an influence, affect quality of product; And need to safeguard cleaning maintenance to the pump housing, impact is produced, wasting manpower and material resources, and also Under Water Pumps is expensive, and user cost is high.Mostly the general liquefied chlorine cistern car process of unloading is to adopt vaporization to unload chlorine method, and the method needs strictly to control temperature and pressure, and makes regular check on and unpick and wash vaporizer, prevent that agene from producing, complicated operation, if agene is cleared up not in time, has certain security risk.
Summary of the invention
The object of the invention is to, for existent defect and deficiency in appeal prior art, provides a kind of liquid chlorine transporting system of producing haloflex.
The technical solution used in the present invention: a kind of liquid chlorine transporting system of producing haloflex, this system comprises A, B, tri-storage chlorine tanks of C, barrier film air compressor, it is characterized in that: described A, B, tri-storage chlorine tank deck faces of C are respectively equipped with suction tude, steam outlet pipe, liquid chlorine inlet tube, each storage chlorine tank bottom surface is respectively equipped with liquid chlorine outer pipe, the steam outlet pipe of each storage chlorine tank is connected on a total steam outlet pipe, each suction tude is connected on a total inlet pipe, each liquid chlorine inlet tube is connected on a total liquid chlorine inlet tube, each liquid chlorine outer pipe is connected on a total liquid chlorine outer pipe, each pipe of each tank is provided with valve control, in the time producing haloflex, total steam outlet pipe is connected with the suction port of diaphragm type compressor, total inlet pipe is connected with the relief opening of diaphragm type compressor, total liquid chlorine outer pipe is connected with workshop reactor, while unloading for liquefied chlorine cistern car, total steam outlet pipe is connected with the suction port of diaphragm type compressor, the relief opening of diaphragm type compressor is connected with tank car pressurized air mouth, the outlet of tank car liquid chlorine is connected with storage chlorine tank liquid chlorine inlet tube.
Principle of the invention explanation: in airtight condition, at a certain temperature, the pressure having in the steam balancing each other with gas or liquid is called saturation vapor pressure, same substance has different vapour tensions under different temperatures, and increase along with the rising of temperature, after the gas in storage chlorine pipe is extracted out, air pressure in this tank reduces, storage chlorine pipe is temperature-resistant, be gas chlorine for the vapor tension that reaches capacity has again part liquid chlorine vaporizing, in the time having pressure difference in the container of two connections, liquid can flow to from one end of high pressure one end of low pressure.
When producing in haloflex process, if use the liquid chlorine of storage chlorine tank B as raw materials, use gas chlorine in storage chlorine tank A to provide highpressure for storing up chlorine tank B, when carrying out, chlorination opens storage chlorine tank A gas phase steam outlet pipe valve and the gas phase suction tude valve of storage chlorine tank B and total steam outlet pipe and suction tude valve, start diaphragm type compressor, chlorine in storage chlorine tank A is through tank A steam outlet pipe, total steam outlet pipe enters cylinder compression by diaphragm type compressor Aspirating valves, now in tank A, for having part liquid chlorine, the vapor tension that reaches capacity is vaporizated into gas chlorine, then in compressor compression after through barrier film engine exhaust valve, total inlet pipe, storage chlorine tank B suction tude enters storage chlorine tank B, making to store up chlorine tank B internal pressure strengthens, thereby liquid chlorine is pressed into workshop reactor continually through the liquid chlorine outlet conduit of storage chlorine tank B.While unloading for tank car, can be transported to again in tank car liquid chlorine tank by using diaphragm type compressor to extract the gas chlorine in storage chlorine tank A out compression, strengthen tank car liquid chlorine tank internal air pressure, utilize the draught head in tank car liquid chlorine tank internal air pressure and storage chlorine tank B or C, liquid chlorine is flowed in storage chlorine tank B or C by tank car liquid chlorine tank.
Beneficial effect of the present invention: be transported to again in another tank by using diaphragm type compressor to extract the gas chlorine in storage chlorine tank out compression, strengthen another tank internal air pressure, utilize pressure difference that liquid chlorine is pressed into reactor or liquid chlorine is entered to store up chlorine tank by tank car liquid chlorine tank pressure, time saving and energy saving, safe and reliable, save again cost.
