Abstract

The utility model provides a siliceous whitewashed fluid electric heater of cold hydrogenation, it includes furnace, is provided with the coil pipe in the furnace, the coil pipe periphery is provided with electric heater unit. Prevent effectively that the electrothermal tube surface from forming the protective layer, guaranteed the inside heat -conduction efficiency of electrothermal tube, prevented burning out of electrothermal tube to the damage of whole heater has effectively been avoided.

Description

A kind of cold hydrogenation silicon powder-containing electric heater for fluid

Technical field

The utility model relates to the technical field of electric heater, particularly one cold hydrogenation silicon powder-containing electric heater for fluid.

Background technology

Existing cold hydrogenization of silicon tetrachloride electric heater adopts electrothermal tube heating, and containing a large amount of silica flour in air-flow, in heating process, silicon powder deposit is on electrothermal tube surface; form thermal-protective coating; in the course of time not out, internal temperature is more and more higher for the heat transfer of electrothermal tube inside, until burn out electrothermal tube.

Summary of the invention

For the deficiency that prior art exists; the utility model provides a kind of cold hydrogenation silicon powder-containing fluid heating electric heater, effectively prevents electrothermal tube surface from forming protective layer, ensure that the heat conduction efficiency of electrothermal tube inside; prevent burning out of electrothermal tube, thus avoid the damage of whole heater.

To achieve these goals, the utility model realizes by the following technical solutions: a kind of cold hydrogenation silicon powder-containing fluid heating electric heater, it comprises burner hearth, is provided with coil pipe in burner hearth, and described coil pipe periphery is provided with electric heater unit.

It improves further and is: burner hearth comprises upper furnace and lower hearth, and upper furnace and described lower hearth removably connect; Electric heater unit is heating wire; Be provided with multilayer coil pipe in burner hearth, between multilayer coil pipe, be communicated with formation import, an outlet.

In said structure of the present utility model; owing to being provided with coil pipe in burner hearth; coil pipe periphery is provided with electric heater unit; cold hydrogenation silicon powder-containing fluid passes in coil pipe; by the electric heater unit heating outside coil pipe; effectively prevent electrothermal tube surface from forming protective layer, avoid the damage of burner hearth, thus avoid the damage of whole heater.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model cold hydrogenation silicon powder-containing fluid heating electric heater is further described:

See Fig. 1, Fig. 2 and Fig. 3, a kind of cold hydrogenation silicon powder-containing electric heater for fluid, it comprises burner hearth 1, burner hearth 1 comprises upper furnace 1a and lower hearth 1b, in burner hearth, 1 is provided with three layers of coil pipe 2, formation import 3 is communicated with between three layers of coil pipe, an outlet 4, three layers of coil pipe 2 periphery are provided with electricity and add silk 5, the fluids such as silicon powder-containing silicon tetrachloride or hydrogen walk coil pipe 2 tube side, shell side thermal field is arranged in outside, effectively prevent silicon from forming protective layer on electrothermal tube surface, avoid the damage of burner hearth, thus avoid the damage of whole heater, thorax comprises upper furnace and lower hearth, thermal field is divided two-layer up and down, can conveniently take apart, coil pipe is changed.

Burner hearth 1 periphery is provided with heat-insulation layer 6, prevents heat from leaking, improves the efficiency of heating surface.

Be provided with thermocouple 7 in burner hearth 1, realize the measurement to temperature in burner hearth.

In above-described embodiment, the mounting means of heating wire has multiple, can be arranged on coil pipe periphery, also can layered arrangement, as long as realizing the heating of hydrogenation silicon powder-containing fluid cold in coil pipe is all protection domain of the present utility model.

The number of plies of coil pipe also can be arranged according to the space size of burner hearth.

Silicon powder deposit, in coil pipe, after a period of time, as fire box temperature raises obviously, represents that silica flour thickness seriously hinders heat transfer, opens burner hearth the first half, taken out by this section of coil pipe and change, and puts into or for subsequent use after clearing up.

Silicon powder deposit is in coil pipe, and judge that deposit thickness is by fire box temperature, easy to operate, burner hearth heating part is unaffected, and the life-span is long, solves cold hydrogenation silicon powder-containing fluid heating problem again with lower cost.

Judge whether this cleaning silica flour because this utility model have employed by fire box temperature, burner hearth is unaffected, obtains cold hydrogenation silicon powder-containing fluid heating problem with lower cost.
