Abstract
The utility model discloses a high contain thermowell for salt waste liquid furnace high temperature zone, including heat-resisting steel casing pipe and thermocouple, the slope of heat-resisting steel casing pipe runs through in the oven, resistant material has been cup jointed in the outside of heat-resisting steel casing pipe, the right-hand member of heat-resisting steel casing pipe is connected with the flange, the thermocouple runs through the back via the middle part of flange and inserts to heat-resisting steel casing intraduct. The utility model uses heat-resistant stainless steel as heat-resistant steel sleeve, then pins are made on the heat-resistant steel sleeve, and a refractory material with a certain thickness is made, thereby protecting the heat-resistant steel sleeve from being corroded and oxidized easily; the heat-resistant steel sleeve has a certain inclination angle, so that the molten salt flowing along the furnace wall cannot flow backwards or fill the heat-resistant steel sleeve, and large molten salt cannot fall down and directly hit a thermocouple, so that the thermocouple is protected.
Description
Technical Field
The utility model relates to a thermowell technical field specifically is a thermowell for high salt waste liquid stove high temperature section.
Background
The original thermocouple connecting pipe is designed to be only provided with a flange interface on the waste liquid furnace, and because the high-salt-content waste liquid furnace has molten salt flowing along the furnace wall, the molten salt falls on a thermocouple sleeve by smashing at a high altitude, and the thermocouple is poor in rigidity at a high temperature and is extremely easy to break by smashing. Therefore, the thermowell for the high-temperature section of the high-salt-content waste liquid furnace is provided.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a high thermocouple sleeve for salt waste liquid furnace high temperature section to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a high contains thermocouple well for salt waste liquid stove high temperature zone, includes heat-resisting steel casing and thermocouple, heat-resisting steel casing slope runs through in the oven, resistant material has been cup jointed in the outside of heat-resisting steel casing, the right-hand member of heat-resisting steel casing is connected with the flange, the thermocouple runs through the back via the middle part of flange and inserts to heat-resisting steel casing inside.
As a further optimization of the technical scheme, the refractory material is fixed on the outer side of the heat-resistant steel sleeve through a plurality of groups of pins which are arranged at equal intervals.
As a further optimization of the technical scheme, the thermocouple is provided with a limiting block integrally formed with the thermocouple, and the limiting block is positioned on the outer side surface of the flange.
As a further optimization of the technical scheme, a plurality of groups of equidistant installation holes are arranged on the flange and are circularly distributed, and the installation holes are used for fixing bolts.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model uses heat-resistant stainless steel as heat-resistant steel sleeve, then pins are made on the heat-resistant steel sleeve, and a refractory material with a certain thickness is made, thereby protecting the heat-resistant steel sleeve from being corroded and oxidized easily;
the heat-resistant steel sleeve has a certain inclination angle, so that the molten salt flowing along the furnace wall cannot flow backwards or fill the heat-resistant steel sleeve, and large molten salt cannot fall down and directly hit a thermocouple, so that the thermocouple is protected.
