Orchid connection, water cooling tube and 1 flanged joint of forced air cooled tube, forced air cooled tube are made of two disks, the self cooling pipe of two flanged joint of the second disk forced air cooled tube
One, self cooling pipe is also made of two disks, and export b by the self cooling pipe two of the second disk connects with external equipment material pipe.
The connector uses water-cooling jacket threeway pattern, and threeway bottom is blocked by blind plugging head；Pacify water cooling tube front end
Equipped with dechlorination hydrogen ring.
Hydrogen inlet is provided with the dechlorination hydrogen ring；Water cooling tube chuck front end is provided with hot water inlet latter end chuck and sets
It is equipped with hot water outlet；One chuck front end of forced air cooled tube sets cold wind import；Two chuck end of forced air cooled tube is provided with hot-blast outlet.
Provided by the present invention for the collector of fume colloidal silica production, have the beneficial effect that：
1st, elbow is substituted using the threeway with blind plugging head, it is therefore prevented that erosion corrosion of the air-flow to elbow baffling inner wall, and can stockpile
Impurity in reaction gas flow, reduces impurity content in product, and blind plugging head (2) is dismantled when stopping, anti-in workshop section before can conveniently checking
Answer stove inner wall situation.
2nd, the external hydrogen of dechlorination hydrogen ring and the chlorine reaction in pipeline tail gas, reduce free chlorine contents in tail gas.
3rd, forced air cooled tube chuck can pre- thermal response air, reduce steam consumption.
Equipment erosion corrosion, the reduction product impurity run into existing white carbon accumulation process can be solved, extends and drives
Time, reduces tail gas free chlorine contents, energy-saving, reduces cost.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is the structure diagram of the present invention；Flanged joint section（1）, plug（2）, dechlorination hydrogen ring（3）, water cooling tube（4）, it is air-cooled
Guan Yi（5-1）, forced air cooled tube two（5-2）, self cooling pipe one（6-1）, self cooling pipe two（6-2）, hydrogen inlet（3-1）, hot water inlet（4-
1）, hot water outlet（4-2）, cold wind import（5-1-1）Plus hot-blast outlet（5-2-2）.
Embodiment
Such as Fig. 1, a kind of collector for fume colloidal silica production, including by flange coupling connector, dechlorination hydrogen ring and, water
Cold pipe, forced air cooled tube, self cooling pipe, use jacketed piping, chuck between each pipeline section by flange flanged joint, water cooling tube and forced air cooled tube
The mouth of pipe is sequentially connected using flange.
It is a kind of for fume colloidal silica production collector, including including flanged joint section 1, plug 2, dechlorination hydrogen ring 3,
Water cooling tube 4, one 5-1 of forced air cooled tube, two 5-2 of forced air cooled tube, one 6-1 of self cooling pipe, two 6-2 of self cooling pipe；1 lower nozzle of flanged joint section is led to
First 2 closure of blind plugging is crossed, 1 upper orifice a of flanged joint section is connected with external flanges, the right part mouth of pipe and 3 method of collector dechlorination hydrogen ring
Orchid connection, dechlorination hydrogen ring 3 and 4 flanged joint of water cooling tube, water cooling tube 4 and one 5-1 flanged joints of forced air cooled tube, forced air cooled tube is by two disk groups
Into self cooling one 6-1 of pipe of two 5-2 flanged joints of the second disk forced air cooled tube, self cooling pipe is also made of two disks, passes through the self cooling pipe two of the second disk
6-2 outlets b is connected with external equipment material pipe.
The connector 1 uses water-cooling jacket threeway pattern, and threeway bottom passes through first 2 closure of blind plugging；4 front end of water cooling tube
