technical problem to be solved by this invention is to provide a kind of steam raising plant that accurately can control quantity of steam.
for solving above technical problem, the present invention adopts following technical scheme:
a kind of steam raising plant, comprise multiple Heater group with water inlet and steam (vapor) outlet, described Heater group comprises at least one ptc heater, described steam raising plant also comprises the water supplying unit be connected with described water inlet, and described water supplying unit comprises water inlet pipe, the measuring pump that accurately can control described water inlet pipe flow be arranged on described water inlet pipe.
particularly, be in parallel between described multiple Heater group, each Heater group is connected with described water inlet pipe respectively by water inlet pipe, and described water inlet pipe is provided with magnetic valve.
particularly, described Heater group comprises more than two ptc heaters.
more specifically, described more than two ptc heaters are in series, or two in described more than two ptc heaters are in parallel, are in series between remaining ptc heater.
again particularly, described Heater group is made up of the first ptc heater, the second ptc heater and the 3rd ptc heater, wherein the first ptc heater and the second ptc heater are in parallel, and their water inlet is communicated with described water inlet pipe, the water inlet of the 3rd described ptc heater is communicated with the steam (vapor) outlet of the first ptc heater with the second ptc heater.
particularly, described water supplying unit also comprises the Calibration Column for verifying described measuring pump, and described Calibration Column is connected with the water inlet pipe of the import department near described measuring pump by demarcating arm, and described demarcation arm is provided with hand-operated valve.
particularly, described water supplying unit also comprises the buffer of the flow for stable described water inlet pipe, the counterbalance valve for the pressure of stable described water inlet pipe, and described buffer and described counterbalance valve are separately positioned on the water inlet pipe between described measuring pump and described multiple Heater group.
particularly, described water supplying unit also comprises the flowmeter observing the flow of described water inlet pipe for people on the water inlet pipe that is arranged between described measuring pump and described multiple Heater group.
particularly, described steam raising plant also comprises the steam outlet pipe be connected with described steam (vapor) outlet, the demister for filtering the globule of not vaporizing completely be arranged on described steam outlet pipe.
more specifically, described steam raising plant also comprise be arranged between described water inlet pipe and described steam outlet pipe for people observe liquid level quartzy liquid level gauge, be arranged on Pressure gauge on described steam outlet pipe and thermometer.
beneficial effect of the present invention is:
the present invention by arranging measuring pump on water inlet pipe, and adopt multiple ptc heater to heat, measuring pump accurately can control the influx of water, and ptc heater can dry combustion method, therefore the water flowed into wherein can be changed into water vapour completely, thus accurately can control the quantity of steam of generation, can be used for needing accurately to control in the reaction of steam addition.
