Problems solved by technology

Disadvantages: use hard tap water for heat exchange to produce steam, water quality evaporates and sinks, hard water substances, and scale is formed, which is attached to the inner wall of the straight heat exchange pipe, resulting in thickening of the tank body, a significant decrease in heat transfer rate, and a large amount of unused heat Discharge, waste heat discharge temperature increases, resulting in energy waste
The water pipe heating straight pipe is connected, the volume is high, the heat utilization rate is low, and the exhaust gas discharge temperature is high
[0005] ②. Catering three-door seafood steaming cabinet, dim sum steaming oven, steam water tank heat exchanger adopts blast flame combustion chamber for heat exchange, flat-bottomed flat pan type heating or heat exchange method with a small amount of water pipe heating, and the heat exchange structure volume Small, disadvantages: pan-type heating in the combustion chamber, low heat utilization rate, high exhaust temperature, blast-type combustion, small heat exchanger structure, flat-bottom heating, strong blast directly discharge a large amount of unused heat, resulting in energy consumption a lot of waste
Disadvantages: The edges of the two stamping plates are welded and fixed, which cannot withstand high pressure leak detection, and the gallbladder is shaped
S-type channel stamping plate, the flame passes through smoothly and without obstructions, the heat utilization rate is insufficient, the exhaust gas discharge temperature is high, and energy is wasted

Abstract

The invention discloses a gas steam / hot water / boiled water three-heat-in-one stainless steel round tube and round liner heat exchanger. The heat exchanger comprises a main liner body and an automatic water feeding tank, wherein the main liner body comprises a water holding barrel, a burning chamber, an upper plate, a cover plate and multiple quick heat exchange tubes; a water holding space is formed between the upper plate and the burning chamber; the cover plate is positioned rightly above the upper plate; a tail gas smoke collecting chamber is formed between the cover plate and the upper plate; the heat exchanger is manufactured by using a food grade stainless steel material, accords with the sanitary safety standard of food manufacturing, is high in efficiency of heat utilization design technology, is low in tail gas discharge temperature, saves the energy, protects the environment, is small in volume, and can be matched in multiple forms to be applied to the production of finished products; an innovative energy-saving three-heat-in-one heat exchange technology synchronously provides three heat exchange results of steam, hot water and boiled water; the pressure leakage of high-pressure air of the heat exchanger is detected; the stainless steel structure of the heat exchanger is fixed by a maximum value; the metal fatigue resistance is improved; the heat expansion and cold contraction coefficient is reduced; and the product durability is improved.

Description

technical field [0001] The invention relates to the technology in the field of food sanitation and safety production, in particular to a three-heat heat exchanger of gas, steam, hot water, and boiling water, and a stainless steel round tube and round gallbladder heat exchanger. Background technique [0002] At present, coal-fired atmospheric pressure steam boilers made of iron are widely used in the food processing of tofu rooms and steamed bun rooms. The steam tank heat exchangers of catering steamers, three-door seafood steaming cabinets, and dim sum steamers are mostly made of iron materials. Rust of high quality materials is exchanged with water heat, and water quality produces rust, which does not meet the hygiene and safety standards of food processing and production. [0003] In addition, the following heat transfer technologies are currently available: [0004] ①. The heat exchange between the coal-fired atmospheric pressure steam boiler and water adopts butt weldin...
