Abstract

The utility model discloses a thermocouple for a reforming furnace. An inner protection sleeve (2) of two built-in couple cores (1) goes through an outer protection sleeve (3) and is sealed and fixed through a screw thread seal cutting sleeve (4). A flange is welded on the outer wall of the outer protection sleeve. A wiring box and protection cover (7) is welded at the end part of the outer protection sleeve. Couple core wiring posts (6) are welded on the wiring box and protection cover (7). The metal wires of the couple cores (1) are connected with the couple core wiring posts (6). A wiring box end cap (8) is screwed on the wiring box and protection cover (7). The thermocouple for a reforming furnace is formed overall. In the thermocouple, the inner protection sleeve and the outer protection sleeve with a wall thickness of 4-6mm are arranged around the couple cores and are fixed through the screw thread seal cutting sleeve, and the wiring box and protection cover has an blocking effect on medium ejected from a reforming furnace by accident. The service life is prolonged, the usage cost is saved, production potential safety hazards are eliminated, is suitable for usage in a reforming furnace with poor working condition environments of high temperature, high voltage, corrosivity and others for a long time.

Description

Reburner thermopair
Technical field
The utility model relates to temperature plug, especially a kind of for measuring the thermopair of temperature in coal gas reburner.
Background technology
In production run with coal conversion legal system gas making body in reburner, temperature in reburner is for a long time 1500 ℃ of left and right, in reburner, also will maintain elevated pressures, working condition is severe complicated dangerous, thereby the instrument of measuring temperature in reburner has been proposed to very high request.The serviceable life of the common thermocouple in the past using is shorter, often needs to change, and causes use cost to strengthen.Even tend to that thermopair occurs and be burned, high-temperature medium sprays along thermocouple mounting hole the event that jeopardizes safety in production in reburner.
Summary of the invention
The purpose of this utility model is: a kind of reburner thermopair is provided, and this thermopair can increase the service life, and saves use cost, makes medium from unexpected ejection in reburner, not guarantee production safety.
Technical solution of the present utility model is: this thermopair comprises even core, internal protective cover pipe, outside protective case, thread seal cutting ferrule, flange, even core binding post, terminal box hold concurrently protective cover and terminal box end cap, the internal protective cover pipe of built-in two even cores penetrates in outside protective case and by the sealing of thread seal cutting ferrule and fixes, the outer wall welding flange of outside protective case, the end Welding junction box of the outside protective case protective cover of holding concurrently, terminal box is held concurrently on protective cover and is welded even core binding post, the tinsel of even core connects even core binding post, terminal box end cap is screwed in terminal box and holds concurrently on protective cover, entirety forms reburner thermopair.
Wherein, outside protective case is formed by cylindrical, massive stainless steel Drilling operation, and wall thickness is 4-6mm.
The beneficial effects of the utility model are: 1, inside and outside double shielding sleeve pipe is set around even core and is fixed by thread seal cutting ferrule, outside protective case is formed by cylindrical, massive stainless steel Drilling operation, wall thickness is 4-6mm, and this thermopair can increase the service life, and saves use cost; 2, terminal box end cap is screwed in terminal box and holds concurrently on protective cover, and the terminal box protective cover of holding concurrently formed medium from the stopping of unexpected ejection in reburner, made medium from unexpected ejection in reburner, not guarantee production safety; 3, this thermopair can be suitable for using in the reburner of High Temperature High Pressure, corrosivity and other bad working environments environment for a long time, and extend serviceable life, makes medium from unexpected ejection in reburner, not eliminate production safety hidden danger.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 even core, 2 internal protective cover pipes, 3 outside protective cases, 4 thread seal cutting ferrules, 5 flanges, 6 even core binding posts, the 7 terminal boxes protective cover of holding concurrently, 8 terminal box end caps.
Embodiment
As shown in Figure 1, this thermopair comprises even core 1, internal protective cover pipe 2, outside protective case 3, thread seal cutting ferrule 4, flange 5, even core binding post 6, terminal box hold concurrently protective cover 7 and terminal box end cap 8, the internal protective cover pipe 2 of built-in two even cores 1 penetrates in outside protective case 3 and seals fixing by thread seal cutting ferrule 4, the outer wall welding flange 5 of outside protective case, the end Welding junction box of the outside protective case protective cover 7 of holding concurrently, terminal box is held concurrently on protective cover 7 and is welded even core binding post 6, the tinsel of even core 1 connects even core binding post 6, terminal box end cap 8 is screwed in terminal box and holds concurrently on protective cover 7, entirety forms reburner thermopair.
Wherein, outside protective case 3 is formed by cylindrical, massive stainless steel Drilling operation, and wall thickness is 4-6mm.

Claims (2)
