Problems solved by technology

However, during the operation, a large amount of tar was deposited on the inner wall of the riser heat exchanger
Environmental pollution caused by tar combustion and heat transfer problems exacerbated by tar adsorption
When the ascending pipe alternates between dry burning and water flow, the metal material of the pipe body is prone to high-temperature oxidation and high-temperature creep, resulting in deformation and water leakage of the cylinder body, affecting the normal production of the coke oven
In this way, the original riser heat exchanger is useless

Embodiment 1

[0040] The turtle net 5 welded in the inner wall of the rising tube heat exchanger, and the tilt heat storage layer 2 is poured, and the heat storage heat storage layer 2 is attached to the inner wall of the rising tube heat exchanger 1. The turtle noodle 5 has a high temperature resistant to high-resistance, which can enhance the fixation effect of the insulation heat storage layer 2, making it more secure.

[0041] A transformation method of a rising tube heat exchanger, including the following steps:

[0042] a. Use a grinding wheel or sand blasting machine to grind the inner wall of the rising tube 1, leak the inner steel pipe;

[0043] b. Welded Turtle Net 5, in the rising tube heat exchanger inner wall welding turtle.com 5;

[0044] c. Rising tube heat exchanger 1 Press: The welded rising tube heat exchanger 1 is pressed according to the pressure on the requirements of the rising tube heat exchanger, and the pressure maintenance time is greater than 30 min;

[0045] Among th...

Embodiment 2

[0051] like Figure 3-4 , The inner wall of the rising tube heat exchanger a plurality of the inner wall of rivet welding, heat storage pouring insulation layer on the rivet, the insulating layer 2 against the heat storage of the riser; embodiment according to the present embodiment , the rivet is welded to a uniform shape of the inner wall of the riser pipe heat exchanger 1, to ensure uniform force, the rivet is a Y-type or T-shaped construction helps prevent heat accumulation layer rigid front insulating collapse the material shrinks uniformly, avoiding cracking.

[0052] The method of transformation of one kind of the riser pipe heat exchanger, comprising the steps of:

[0053] . A coke with a grinder or the blasting machine the riser inner wall of the heat exchanger 1 tar polished clean, leaking pipe wall;

[0054] . B rivet welding: the inner wall of the riser 1 uniformly heat welding said rivet;

[0055] . C suppress rising tube heat exchanger 1: The welded heat exchanger 1 o...

Embodiment 3

[0060] like Figure 5 Shown, the ascending upper, middle and lower average number of welded heat exchanger tube is fixed to the ring bars 3, and between the riser pipe and the middle heat exchanger to the fixed upper ribs, the central ring the lower ring is fixedly connected to the four ribs axially fixed between the fixing rib 34, a plurality of uniformly welded to rivet the riser pipe inner wall, the shape of the rivet is Y or T, hexagonal mesh 5 is mounted in the heat exchanger the mouth of said hoop-shaped holding ribs 3 and 4 of the axially fixed ribs consisting of 3, the ribs 4 is axially fixed, and the placing of the rivets 5 in the hexagonal mesh bars secured to said ring said thermal storage heat insulating layer 2 ,, the heat storage layer 2 against the inner wall of the riser tube heat exchanger 1.

[0061] Specifically, the fixed ring with axially fixed ribs 3 and ribs 4 Stainless steel bar, the riser inner wall of the heat exchanger 1 are welded one week four fixed ba...

Abstract

The invention discloses a water jacket ascension pipe heat exchanger with a heat insulation and storage layer and a transformation method of the water jacket ascension pipe heat exchanger. The water jacket ascension pipe heat exchanger with the heat insulation and storage layer comprises an ascension pipe heat exchanger body, and the heat insulation and storage layer is attached to the inner wall of the ascension pipe heat exchanger. The transformation method of the ascension pipe heat exchanger comprises the steps of polishing the inner wall of the ascension pipe heat exchanger, welding a fixing piece, pressing the ascension pipe heat exchanger, pouring the heat insulation and storage layer, and drying or air-drying and maintaining the heat insulation and storage layer. The problem that the inner wall of an original ascension pipe heat exchanger is coked is solved, meanwhile, the wall temperature change of the inner wall of the original ascension pipe heat exchanger is reduced, high-temperature oxidation and high-temperature creep of a pipe body metal material are reduced, and the service life of the original ascension pipe heat exchanger is prolonged by 3-5 years.

Description

Technical field [0001] The present invention relates to a coke oven rising tube heat exchanger device, and more particularly to a water clamping rising tube heat exchanger having a heat storage layer and a modification thereof. Background technique [0002] The efficient recycling and utilization of the coke oven from the coke oven crashes in the coke process is the main direction of establishing resource saves, environmentally friendly green coking plants, and is also one of the main ways to reduce coke oven energy consumption. [0003] The coal waste of coal waste coal is now widely used. However, the inner wall of the rising tube heat exchanger appears in the operation process. The targeting caused environmental pollution and causes heat transfer problems more deteriorated due to tar adsorption. When the rising tube occurs, the tubular metal material is easily oxidized, high temperature creep, causing the cylindrical deformation, leaking, and affects the normal production of t...
